Sentences are made of small packages of words that are able to express a complete sense of thoughts. Sentences make easy to understand the others ideas and help to learn information. Without using sentences, we cannot express our thoughts, emptions, feelings, ideas or general speeches as well.
Now we are going to learn about the types of sentences according to their structure. Before this, we have to know the structure of sentence.
What is Sentence Structure?

Types of sentence according to structure
Every meaningful thing has its own structure. You know what, there is nothing in this world which don’t have a basic structure.

Like – buildings have their own structure chair, table, furniture all have their structures. Foods, chemicals, we writing with pen on paper or board, all have structures. Our talks, sentences also have structures. Structure means formation of something. A simple declarative sentence basically have the following structure. i.e –
Sub + verb + object.
Ex – (a). I read a book.
(b) People visit learnitech website.
It is a very simple structured sentence that express only a general idea. If you want to express something negative, then your sentence structure will be:
Sub + Auxiliary Verb + not + main verb + object.
Ex – I do not read a book.
Here, we should learn about clause to get broad knowledge about sentence structure. We cannot understand the structure of sentence without knowing clause.

What is Clause?
A clause is a unit of some words that consists of a subject of a word. A clause is different from a phrase. Phrase do not contain subject plus verb. For example –
In the morning, at the night, to your home, at the college, before sleep etc.
Types of clause:
There are basically two major types of clause. i.e.
  1. Main or independent or principal clause.
  2. Subordinate or dependent clause.
Example: He is buying a pant which is nice.
Here the first part “He is buying a pant” is Independent clause. And the other part “which is nice” is dependent clause.
Independent clause can be a complete sentence alone. On the other hand, dependent clause cannot be a complete sentence.
Phrase:
We can identify phrases by some excellent tricks.
See ‘I saw a bird.’
Here ‘I’ subject, ‘saw’ finite verb or main verb, and ‘a bird’ is object.
Now, ‘I saw a bird having red feathers’. Look here, the object is extended to ‘a bird having red feathers’. This object says as only one element or noun and they have no main verb or finite verb. So these group of words are unable to make a complete sentence. This type of word groups are called phrase.
In other words, a phrase can be defined as a group of words that have no subject and no finite verb and acts as a small element of any sentence.
Example- ‘I like to take exercise in the morning’. The underlined part is a phrase.
Now it’s time to learn the structure of sentence. According to structure, sentences are of three types.
  1. Simple sentence
  2. Complex sentence
  3. Compound sentence
Simple sentence:
Simple sentence is consist of only one main or independent clause.
Example: I saw the picture.
Here this sentence is consist of a subject (I), a main verb (saw) and an object (the picture) and it expresses a definite and complete idea or thought.
Structural pattern: Subject +finite verb +object + complement.
A simple sentence does not contain any dependent clauses or any conjunction between two independent clauses. It doesn’t have more than one main or independent clauses.
Simple SentenceNot Simple Sentence
Tina works well.Tina works well and confidently.
Dipu likes football.Although Dipu likes football, he hates cricket.
But remember a simple sentence may have a subject which contains conjunction.
Example: Ruma and Suma are the best friends. And underlined “Ruma and Suma” is a subject, not a clause.
Complex sentence:
A complex sentence consists of one or more main or independent clause and one or more dependent clause.
For example – ‘If you work hard, you will prosper in life’.
Here, ‘If you work hard’ is a dependent or subordinate clause. And ‘you will prosper in life’ is main clause.
In a complex sentence, dependent or subordinate clause always begins with some conjunctions. These are – who, where, when, which, while, how, whether, if, that, because, since, as, though, although, till, until, unless, before, after, so that, so……that, whatever, wherever, whoever, whenever etc.
Examples are-
  1. Though he is poor, he is honest.
  2. We eat so that we may live.
  3. I do not know where he lives in.
  4. I will wait for you till night.
  5. I cannot go out since it has been raining for two hours.
Compound sentence:
A compound sentence is a type of sentence which has more than one independent or main or principal clause connected by one or more coordinate conjunctions.
Conjunctions generally use in compound sentence are – and, but, or, both….and, not only…..but also, for, also, yet, not yet, no less than, thus, so, else, still, therefore, otherwise, either…..or, neither…..nor, as well as, accordingly, moreover, nevertheless, on the contrary, while, whereas, however, while, only, consequently etc.
Examples are –
  1. Not only Toma but also Ruma went there.
  2. You must do it or you will be fired.
  3. The teacher taught me that do not tell a lie.
  4. She assured me that she will come.
  5. Either Rafi or Kafi will do the work.

Chinese smartphone player Xiaomi has become the fifth largest smartphone brand in Russia during Q3 2017, according to the latest research from Counterpoint's Market Monitor service. "Xiaomi grew by 325 per cent YoY and was the fastest growing smartphone brand in Russia in both online as well as offline sales," the Associate Director at Counterpoint Research (Counterpoint Technology Market Research), Tarun Pathak, said in a statement.

Smartphone shipments in Russia grew by 7 percent annually and 38 per cent sequentially during Q3 2017. "The Russian handset market grew during this quarter driven by aggressive marketing campaigns by new Chinese brands and subsequent price cuts from all the leading retail chains as consumer spending during third quarter of the year normally remains high due to the new academic year and a 'back-to-school' uptick," said Minakshi Sharma, Research Associate at Counterpoint Research (Counterpoint Technology Market Research).
The online channel smartphone contribution has increased from 12 per cent to 15 per cent YoY in Russia. During this quarter, Xiaomi and Apple were among the leading smartphone brands in online sales. "Apple reached record sales during the third quarter, growing 56 per cent YoY due to a drop in the prices of its previous generation iPhone models, prior to the launch of the new iPhones," Pathak said.
Samsung led the overall and smartphone market with market shares of 20 per cent and 29 per cent respectively during Q3 2017. Global brands captured almost 58 per cent of the smartphone market followed by Chinese brands with 32 per cent market share. Xiaomi (325 per cent), Bright and Quick (177 per cent) and Huawei (140 per cent) were the fastest growing Chinese brands YoY.
However, local smartphone brands like Tele2 and Prestigio grew by 61 per cent and 54 per cent QoQ respectively.

This robot can follow pedestrian traffic rules
NEW YORK: Engineers at Massachusetts Institute of Technology (MIT) have designed an autonomous robot that can keep pace with foot traffic while observing the general social codes that pedestrians follow to avoid oncoming obstacles while keeping up a steady walking pace.

In drive tests, the robot, which resembles a knee-high kiosk on wheels, successfully avoided collisions while keeping up with the average flow of pedestrians, said the researchers who have detailed their robotic design in a paper scheduled to be presented at the IEEE Conference on Intelligent Robots and Systems to be held in Vancouver, Canada, in September.

"Socially aware navigation is a central capability for mobile robots operating in environments that require frequent interactions with pedestrians," said lead author of the study Yu Fan (Steven) Chen.


"For instance, small robots could operate on sidewalks for package and food delivery. Similarly, personal mobility devices could transport people in large, crowded spaces, such as shopping malls, airports, and hospitals," Chen said.

In order for a robot to make its way autonomously through a heavily trafficked environment, it must solve four main challenges -- localisation (knowing where it is in the world), perception (recognising its surroundings), motion planning (identifying the optimal path to a given destination), and control (physically executing its desired path).

Chen and his colleagues used standard approaches to solve the problems of localisation and perception.


For the latter, they outfitted the robot with off-the-shelf sensors, such as webcams, a depth sensor, and a high-resolution lidar sensor.

For the problem of localisation, they used open-source algorithms to map the robot's environment and determine its position. To control the robot, they employed standard methods used to drive autonomous ground vehicles.


For motion planning, the researchers used reinforcement learning, a type of machine learning approach, in which they performed computer simulations to train a robot to take certain paths, given the speed and trajectory of other objects in the environment.


The team also incorporated social norms into this offline training phase, in which they encouraged the robot in simulations to pass on the right, and penalised the robot when it passed on the left.


"We want it to be travelling naturally among people and not be intrusive," study co-author Michael Everett said.


"We want it to be following the same rules as everyone else," Everett added.

LONDON: Scientists have created a new algorithm that enables smartwatches to not only record your exercise session but also detect when you are brushing your teeth or cooking, an advance that will provide a richer and more accurate picture of your daily life.

Current smartwatches can recognise a limited number of particular activities, including yoga and running, but these are programmed in advance.

The new method, developed by researchers from University of Sussex in the UK, enables the technology to discover activities as they happen, not just simply when exercising, but also when brushing your teeth or cutting vegetables.

Traditional models "cluster" together bursts of activity to estimate what a person has been doing, and for how long, researchers said.

For example, a series of continuous steps may be clustered into a walk. Where they falter is that they do not account for pauses or interruptions in the activity, and, so, a walk interrupted with two short stops would be clustered into three separate walks.


The new algorithm tracks ongoing activity, paying close attention to transitioning, as well as the activity itself. In the example above, it assumes that the walk will continue following the short pauses, and therefore holds the data while it waits.

"Current activity-recognition systems usually fail because they are limited to recognising a predefined set of activities, whereas of course human activities are not limited and change with time," said Hristijan Gjoreski of the University of Sussex.


"Here we present a new machine-learning approach that detects new human activities as they happen in real time, and which outperforms competing approaches," Gjoreski said.


Future smartwatches will be able to better analyse and understand our activities by automatically discovering when we engage in some new type of activity.


"This new method for activity discovery paints a far richer, more accurate, picture of daily human life," said Daniel Roggen of University of Sussex.


"As well as for fitness and lifestyle trackers, this can be used in health care scenarios and in fields such as consumer behaviour research," he added.

The system was trained with data from only 1,000 people, and more data would improve it considerably.

WASHINGTON: Scientists have reconstructed faces from people's DNA, an advance that challenges the idea that genetic databases can be anonymous.

Research institutions regularly collect thousands of human genomes to understand diseases.

Most promise volunteers that their identity will be protected.

However, the study published in the journal Proceedings of the National Academy of Sciences shows that in the long run, such anonymity may not be possible.

By training an algorithm to link genetic information with facial features and voices, researchers were able to identify people from their genomes.

"The genome contains all the information that determines your identity. It is used in criminal courts around the world to identify people," said Craig Venter, from the US-based company Human Longevity Inc.


Given a sample of ten people, researchers were able to match headshots with the genome 80% of the time.


The system was trained with data from only 1,000 people, and more data would improve it considerably.


"People need to understand these issues, and not be made these false promises that they will be kept secret," Venter was quoted as saying by 'The Times'.


"Just like Google and others now sell advertising to you based on what is in your searches and emails, you could get adverts targeted to you based on what's in your genome," Venter said.


Medical insurance companies could use the data to find out what diseases a person is susceptible to, and alter their premiums accordingly.

It can take a while to find the optimum video settings for games. Once you've established that performance-quality trade-off, however, you'll see that it was worth the effort.

A top of the line gaming laptop is never going to reach the performance of a similarly-priced gaming desktop. But that doesn't mean that you can't play the latest games. Rather, it just puts a bit of extra pressure on you to ensure that your laptop is optimised for games.

With desktop computers, you can upgrade the hardware. Laptop users will probably know that they can only replace the memory (and perhaps the hard drive) with an upgrade. So, what can you do to ensure your favourite games will play well on your laptop?

These 10 tips (mostly intended for Windows 10) will definitely make a difference.

1. Keep Your Laptop Clean and Dust-Free
First things first. You'll only enjoy improved performance on your laptop with a proactive attitude to physical maintenance. Dust and dirt are the enemies of performance. This detritus will reduce airflow, resulting in a computer that gets too hot.

Once the heat builds, the processor, GPU, and most other components will slow down. This doesn't make for an effective gaming machine.

The best way to deal with this is to remove the dust. Obviously, this isn't the simplest of tasks. Your laptop is probably sealed, and if it isn't, opening it will almost certainly invalidate the warranty. The solution is to use some very specific cleaning techniques. Although intended for a MacBook, our cleaning tips will help for most laptops.


But it isn't just the vents on your laptop that you need to keep clear. If you're using the keyboard regularly (a staple of PC gaming) it's important to ensure there is no dust, food, or other matter able to cause sticky keys. For that matter, you don't want a mucky screen, either.

Our guide to cleaning your laptop computer will help here.

2. Update Your Drivers
There was a time when having the right drivers installed on a Windows PC was considered something of a joke. It was usually initiated by the hardcore Apple Mac users, and worked simply because those computers had such a limited range of hardware available. Any devices that would work already had the drivers installed.

Of course, the situation has moved on somewhat. These days, computers running Windows, macOS, and Linux operating systems are almost all based around the same hardware, with the same architecture. This means that whatever the operating system, keeping device drivers up to date is vital. Fortunately, it's no longer a hassle, either. Instead, it's a slight inconvenience that has been largely swallowed up into the standard OS updates.

However, when it comes to graphic drivers, you might need a more hands-on approach. While Intel graphics — largely unsuitable for hardcore gaming — will enjoy updated drivers via a Windows update, your third-party graphics provider doesn't offer that option. Instead, it's vital that you ensure the management software (such as Nvidia GeForce or AMD Gaming Evolved) is set to automatically update.

3. Install the Latest DirectX Version
A collection of software tools that facilitate the graphics in a video game, DirectX is vital to gaming on Windows (and even on the Xbox consoles). Various iterations of DirectX have seen release over the years. For instance, the last version of DirectX to run on Windows XP was DirectX 9.0. If you're looking for ways to improve performance on your laptop, you shouldn't be running this...

Launched in 2015, DirectX 12 is the latest version, and you should have it installed on your computer. Manual installation of this is rare, however. In most cases, a new version of DirectX gets automatically installed when a new game requires it. At other times, installation of DirectX occurs as part of Windows Update.


To check your current DirectX version, press WIN + R to open the Run menu and enter dxdiag. Wait for the DirectX Diagnostic Tool (DXDiag) to load, then open the Render tab. Here, you'll find information about your dedicated graphics card. In the Drivers pane, look for Direct3D DDI — this should be numbered according to the latest version of DirectX.

As well as having your graphic drivers up to date, it is worth ensuring that your audio drivers are fit for gaming. You can check your audio driver status in the Sound tab of DXDiag, where the date of the installed driver can be found. Note also that Input device drivers are summarized here too.

DXDiag is a good way of checking if your gaming-related hardware is missing any drivers. But if in doubt, run a Windows Update, or manually update the device drivers.

4. Overclock the GPU
Perhaps a bit risky for the beginner, overclocking can force some additional performance out of the graphics card. Tools are available for both AMD and Nvidia GPUs, so you shouldn't have too much trouble with this.

The main problems are with power and heat. Overclocking uses more electricity, so you'll need to adjust your computer's power settings appropriately (see below). But overclocking also increases the heat of the GPU. Usually, this is handled by the laptop's built-in cooling system. This network of heatsinks and fans must be regularly cleaned, as outlined in #1. If not, your laptop will automatically shut down — as a safety precaution — as soon as it gets too hot.

Looking for an overclocking tool for your GPU? The most popular at present is MSI Afterburner, which is suitable for Nvidia and AMD graphics cards.

You can enjoy good results with overclocking, but it is something you must do with care. Our guide to overlocking your GPU safely should help here.

5. Adjust Your Computer's Power Settings
We're focusing on improving performance, and few devices can enjoy improved operation without effective power management. When it comes to laptops — devices that are intended for use away from a permanent power source — power management is a big deal.

Windows gives you some detailed power management options, but using a laptop often means that these are overlooked in favor of maintaining the battery. This makes sense, but for a strong gaming experience, you should have your laptop connected to a power outlet.

Once this is done, it's time to look at your computer's power settings. In Windows 10, you can open Settings > System > Power and sleep > Additional power settings and select the High performance option. It's also worth clicking Change plan settings > Change advanced power settings to check you haven't previously adjusted anything here. You don't want less-than-optimum power settings when squeezing gaming performance from your laptop.

6. Employ Game Mode in Windows 10
This is a tip that anyone can use. Windows 10 is equipped with an Xbox app (if you've removed it, you can re-download it from the Windows Store) which includes several features. Along with screen recording and streaming, the Xbox app also features a Game Mode setting.


To activate this, call up the Xbox panel by pressing WIN + G after the game has launched (preferably with the game menu on screen) and click Settings. In the General tab, click the check in the Use Game Mode for this game box.

Once enabled, this Windows 10 Game Mode will ensure that the OS runs the game with optimum settings, which may involve closing or suspending some background tasks.

7. Close Background Apps
We're assuming you're running Windows 10 for many of these tips. But if not, you don't have Game Mode. Fortunately, there is a manual change you can make to your laptop before you launch a game. Before you click Play in Steam, or double-click the icon on your desktop, ensure all other apps (and even games) are closed.

Once you've done that, take a look at the System Tray. This part of the Windows taskbar lists apps that are running in the background. Right-click each icon and close it. You may like to keep your graphics card management app or a voice chat tool like Discord open, of course!

All that should be running in the taskbar before you launch the game is your digital download service... or nothing at all.

8. Online Gamers: Check Your Network Speed
Gaming performance for your laptop is mostly determined by your hardware, drivers, and how your computer is configured. But if you're playing online games, there is one other element to take into account: your internet connection speed.

Trouble with online gaming is usually centered around lag. This can be due to problems with your internet connection, but often a slow connection between your laptop and the router is to blame. In most cases, your wireless network card will have the most up-to-date drivers, thanks to Windows Update, or whatever system updates your OS has downloaded.


If there's no change after applying updates, consider a wired Ethernet connection to the router. You should also check our tips on reducing lag in online gaming.

9. Manage Automatic Updates

Automatic updates can be a big pain. Take Windows Update, for instance, which can download updates in the background, before reminding you periodically that the update needs installing. Not only can the downloaded update impact performance (peer-to-peer networking shares the updates with other machines), so too can the reminders.

Unfortunately, you can't disable Windows Updates permanently, so you have the following options:

  • Keep your computer offline.
  • Install updates as soon as prompted.
It's unlikely that you'll be able to completely disconnect from the internet if you're using a gaming laptop, so installing those updates as soon as possible is the best answer.

However, it isn't only the operating system that pushes updates out. Digital delivery systems such as Steam use them too. There's a chance that a second game will download updates in the background while you're playing another game. To avoid it, open Steam, and head to Steam > Settings. In the Downloads tab, ensure the Allow downloads during gameplay check box is cleared. Click OK to confirm this change.

You can also manage update rules for individual games. Right-click the game in the Steam menu, select Properties > Updates, and check you're satisfied with the options for Automatic updates and Background downloads. Further tips on managing Steam downloads can potentially improve your laptop gaming performance too.


10. Adjust Texture and Shader Settings


Finally, it's worth looking at your graphics card settings. Here, you'll find master controls for texture and shader details, which will determine how your games look. The memory available to your laptop's GPU limits what options are available here, so it's usually good to select a configuration that offers performance over looks. In short, high-resolution textures will consume your RAM, impacting frame rate.


Note that you can also give individual games their own texture and shader preferences here. This is useful if an older game is capable of running with high settings. Meanwhile, you'll still be able to adjust individual games' video settings as they play, from the video/display settings screen.


It can take a while to find the optimum video settings for games. Once you've established that performance-quality trade-off, however, you'll see that it was worth the effort.
