Even if you don't have to work, eat or sleep, you won't be able to get through all information on blogs and social networks. The problem we face is that much of this information seems very interesting at first glance. Actually, much of the information is unimportant, disposable and it distracts us from more meaningful pursuits. Worse still, when we spend lots of time consuming information from our social media streams, we may find it hard to concentrate on what we’re doing and we have a tendency to forget what we have consumed anyway.

A new study from Sweden’s KTH Royal Institute of Technology has found that too much social media exposure actually reduces your ability to process information and depletes (耗尽) your short-term working memory.

Our working memory plays a critical role in our capacity to filter (过滤) information and remember what is valuable but it is not a limitless resource. Erik Fransen, a professor in Computer Science at KTH and the leader of this is new study on social media overload says this can explain why our capacity (容量) for processing information begins to fail when we attempt to put more information in the working memory.

In fact, when you try to process the information like speech or video, you are going to need partly the same system of working memory, so you are reducing your own working memory capacity. And when you try to store many things in your working memory, you get less good at processing information.

It is the periods of downtime of your brain—preferably disconnected from the distractions of your computer or smartphone—that are needed for memory consolidation (巩固) and transferring important information to your exposure to new information. Besides, you can empty your mind of thoughts quickly to relax completely, go for a short walk or spend a few minutes listening to music. This will help you improve your capacity to process information and increase your productivity.

1.What can we learn about social media overload from Paragraph 1?

A. It distracts our attention.　　 B. It is beneficial to us.

C. It brings us whatever we want.　　 D. It keeps us informed of everything.

2.Why does your capacity for processing information begin to fall sometimes?

A. Much of the information is unimportant.

B. Your working memory is a limited resource.

C. You're less good at processing information.

D. You don't make the most of your brain.

3.Which is recommended to relax your brain?

A. Thinking over things carefully.　　 B. Listening to music for a while.

C. Taking enough physical exercise.　　 D. Focusing more on the present.

高三英语单项填空困难题查看答案及解析

根据短文内容，从短文后的选项中选出能填人空白处的最佳选项。选项中有两项为多余选项。

Can't sleep? You turn all night never seeming to get comfortable, never seeming to feel like you are even close to sleep? I bet you've tried a few different solutions too, warm milk or maybe even sleeping pills. The reason why you can't sleep could be because of many different things. 　　 1.　 　 However, if you want simple solutions to sleep better then the following steps can help you get that great night's sleep:

1. Sleep on your side.

Sleeping on your side is an acquired taste if all you have been doing is stomach sleeping. The side position is best for your neck and for improving breathing which is a common cause for frequently waking. 　　 2.

2. Find the right pillow.

Finding the right pillow is vitally important.　 3. In the side sleeping position the pillow should fill the entire space between your neck and the mattress(床垫).Your head should not be tipped up or down but be in line with your spine（脊椎）．

3. No digital entertainment before bed.

Avoid any forms of digital entertainment at least one hour prior to bed. Digital entertainment means movies, TV, Xbox, computer/laptop use, even a kindle.　 　 4. Trying reading a few pages of non-fiction instead.

4. 5.　

When you eat and got to bed shortly after what happens is that your stomach is still full of food. This prevents you from breathing properly and can lead to a very disturbed sleep.

A. Having a sound sleep is my dream.

B. Wait three hours after eating.

C. There are five steps to have better sleep.

D. Stay away from all forms.

E. Always get a check from a health care provider if you have specific concerns.

F. The best pillows are formed to support the neck.

G. Try placing a pillow between your knees in order to prevent rolling onto your stomach.

What do you use to get around town? A car? A bike? Your feet ? perhaps you should try a segway!

The Segway is perfect for short journeys. It’s an electric vehicle that consists of a platform between two wheels, with a pole that connects the platform to the handlebars. To ride it , you step up onto the platform, and control the Segway by moving your body. Lean forwards to go faster, and back-wards to slow down.

On older models, direction was controlled by a twist grip（扭转把手）on the left handlebar. This varies the speeds between the two motors, and a decrease in the speed of the left wheel would turn the Segway to the left . With newer models you simply lean to the left or right. Meanwhile, a gyroscope （陀螺仪）detects your movements and prevents the machine from falling over. The Segway has a maximum speed of 19 km per hour and a range of about 38 km. after that, you need to plug it and recharge the battery.

Segways are used for a variety of purposes. People with mobility problems can now enjoy walks in the country with their friends and family. Some golfers see them as an alternative to the golf cart . And dog owners now have an easier way to take the dog to the park. A few police forces use Segways, too. They allow officers to move quickly while maintaining contact with the public. They’re also becoming a common sight on airport . However, the most popular use is in tourism , particularly for city tours . Visit any major tourist city in summer, sit outside a cafe for a while and there’s a good chance you’ll see a group of tourists passing on Segways.
