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.

Eating the right thing
A good diet is a fundamental part of sport these days. Aston Villa manager Martin O’Neill’s sport and health experts have chosen a secret weapon --- organic food (food grown without chemicals). Fitness manager Jim Henry eats with his players and said: “I chose to switch to organic food for Aston Villa because I’ve read studies showing that organic food has higher levels of vitamins, minerals and antioxidants.” He believes that the best way to get these is to eat the very best fresh food.
What to eat after the match
Head chef at Aston Villa, lan Edge, feeds players with the best food as soon as they finish an away match. He says: “Food is very important to sports stars and particularly after a game. There is an hour of opportunity when they need to eat to get the best muscle strength, so I hand out meals on the coach on the way home. If we can make one per cent difference to the players by using organic food, then it is worth it.”
Teaching healthy eating
Everyone at Aston Villa enjoys organic food at their training ground. But the club is also worried about the unhealthy diet among local children who prefer sweets and unhealthy fast food. As part of their work in the community, Aston Villa has opened up their kitchen and invited children from local schools to come and learn how to cook with the help of the Villa head chef. Villa midfielder, Nigel ReoCoker, visited the children on the opening day. “The kitchen promotes healthy eating and a healthy lifestyle.” he said.
A final word from the kitchen
