If you are sending a text, watching the TV or listening to the radio, you may want to stop and give this your full attention. Multi-tasking shrinks (萎缩) the brain, research suggests.
A study found that men and women who frequently used several types of technology at the same time had less grey matter in a key part of the brain. University of Sussex researchers said, “Simultaneously using mobile phones, laptops and other media devices could be changing the structure of our brains.”
The finding follows research which has linked multi-tasking with a shortened attention span, depression, anxiety and lower grades at school. The researchers began by asking 75 healthy men and women how often they divided their attention between different types of technology. This could mean sending a text message while listening to music and checking email, or speaking on the phone while watching TV and surfing the web. The volunteers were then given brain scans which showed they had less grey matter in a region called the anterior cingulate cortex (ACC). The findings held even when differences in personality were taken into account.
The study, published in the journal PLOS ONE, is the first to make a link between multi-tasking and the structure of the brain.
Researcher Kep Kee Loh said, “Media multi-tasking is becoming more common in our lives today and there is increasing concern about its impacts on our cognition and social-emotional well-being.”
He added that more research is needed to prove that multi-tasking shrinks the brain. This is because it is also possible that people with less grey matter in the ACC are more drawn to using lots of small devices simultaneously.
Scientists have previously demonstrated brain structure can be changed on prolonged exposure to new environments and experience. Other studies have shown that training — such as learning to juggle or taxi drivers learning the map of London — can increase grey-matter densities (密度) in certain parts. Experts have also warned of the harmful impact technology can have on our memory and attention span.
1.According to Kep Kee Loh, ________.
A. the link between multi-tasking and brain shrinkage needs further research
B. people with less grey matter in the ACC are more attracted to multi-tasking
C. multi-tasking has harmful impacts on our cognition and social-emotional well-being
D. multi-tasking leads to a shortened attention span, depression, anxiety and lower grades
2.Which of the following is NOT mentioned in the passage?
A. What multi-tasking is probably linked with.
B. How researchers draw inferences about multi-tasking.
C. How different health conditions affect brain structure.
D. Significance and limits of the research from University of Sussex .
3.The purpose of the passage is to ________.
A. compare the latest research with previous ones

Some people are so rude!
Who sends an email or a text message that just says “Thank you”？ Who leaves a voice mail message rather than texts you? Who asks for a fact easily found on Google? Don’t these people realize that they’re wasting your time?
Maybe I’m the rude one for not appreciating life’s little politeness. But many social agreed standards just don’t make sense to people drowning in digital communication.
In texts, you don’t have to declare who you are or even say hello. Email, too, is slower than a text. Voice mail is a now impolite way of trying to connect.
My father learned this lesson after leaving me a dozen voice mail messages, none of which I listened to. Exasperated, he called my sister to express his dissatisfaction that I never returned his phone calls. “Why are you leaving him voice mail？” my sister asked. “Just text him.”
In the age of the smartphone, there is no reason to ask onceacceptable questions about: the weather forecast, a business’s phone number, or directions to a house, a restaurant, which can be easily found on Google Maps. But people still ask these things. And when you answer, they respond with a thankyou email.
How to handle these differing standards? Easy. Consider your audience. Some people, especially older ones, appreciate a thankyou message. Others, like me, want no reply.
The anthropologist (人类学家) Margaret Mead once said that in traditional societies, the young learn from the old. But in modern societies, the old can also learn from the young. Here’s hoping that politeness never goes out of fashion but that timewasting forms of communication do.
1.What does the underlined word “Exasperated” mean in the fifth paragraph?
A.Worried. B.Surprised.
C.Annoyed. D.Tired.
2.Why didn’t the writer reply to his father?
A.He liked text messages better.
B.He enjoyed checking his voice mail.
C.He didn’t receive any voice mail messages.
D.He didn’t want to talk with his father.
3.Which of the following does the writer agree to?
A.People needn’t learn from one another in traditional societies.
B.Dealing with voice mail should vary with each individual.
C.People needn’t turn to Google for help when in trouble.
D.Declaring who you are or saying hello in texts is necessary.
4.What’s the best title for this passage?
A.Nowadays: what should we do with text messages?
B.Nowadays: do you like leaving others a voice message?
C.Nowadays: what means should we use in communication?
D.Nowadays: do you need a thankyou message?

The earth is dying before us yet we sit and watch. If the TV or the game system breaks, we run off to the stores to get it fixed immediately no matter what the cost. Why aren’t we willing to fix our earth? Are our televisions and game systems more important to us than where we live? Where shall we continue to live, until the end of time?
The earth is our home and cannot be replaced. We must take care of it. We have come up with so much technology that limits us instead of helping us. Take that game system we run to repair. What does it do? It occupies kids’ time! The earth has already given kids plenty of entertainment in the forms of fields and hills, forests and plains, water and land. However, instead of using what the earth has given us, and helping kids by giving them exercise as they run around, we decide to ruin kids’ minds with game systems that glue them to the screen for hours, and make them ignore their homework and chores. We have polluted this earth by making these things which do not even help in any way!
We have already messed up this world, we have ruined the air, water, and animals that it has so willingly provided for us. We need to stop this destruction of life and bring back the world we had before. It will not be easy, but everybody can help! What about something as simple as turning the lights off when you leave a room? Recycling what can be recycled? Picking up litter? Donating money to an environmental organization? None of these things are very hard. We can’t just always say, “Oh, the earth is a mess. Ah, well, those big companies that are polluting so much can stop and fix it.” Instead, we need to help out. It’s not only those big companies; it’s everyday things that we do too that are ruining the earth. So stop and think about what you can do to make a difference to our world!

You can find language pollution whenever you open a newspaper or turn on your TV set, listen to a popular song at various advertisements. Language pollution exists almost everywhere and can be seen in the following places:
1. Chinese characters are written in the complex (复杂的 ) form. Although simplified Chinese characters were accepted for use many years ago, it seems that more and more people like Chinese characters written in the complex form.
2. Many goods are produced in China but carry foreign names, which sound strange and have no meaning at all.
3. Words and expressions being used have a bad meaning. "Ba"(霸), which means bully in Chinese, is one example. Now there are a lot of goods, restaurants, even factories or firms, with "Ba" in their names.
4. There are too many incorrect grammatical expressions. Some films have strange names and incorrect grammatical structures. "Ai ni mei shang liang', which means "I love you without consulting", is grammatically incorrect and this kind of expression is now becoming popular.
Some language experts point out that language pollution must be done away with, which is an idea shared by myself and many others.

If you like texting and are trying to lose weight, a new study found that using texting(发短信) to track diet and exercise habits may help you lose weight.
Previous research has shown that keeping food and exercise diaries improves the likelihood of success when you are using it to lose weight. Using a computer or a pen and paper to record information, however, can be a burden and cause some people to give up.
Duke University researchers said using text messages to track eating and exercise habits can save time, and increase the chances that people will stick with their weight-loss rules.
The study included 26 obese/fat women with an average age of 38. The women used daily texting as part of their weight-loss program. The text messages focused on tracking personalized goals, such as avoiding sugary drinks or walking 10,000 steps a day. Messages also provided brief feedback (反馈) and tips.
Every morning, the women received a text from an automated system that said, “Please text yesterday’s personal information of steps you walked and how many sugary drinks you had.” Based on the women's responses to the text message, the system sent another text with personalized feedback and tips.
After six months, the women who used daily texting lost an average of nearly 3 pounds, while another group of women who used traditional methods to keep food and exercise diaries gained an average of 2.5 pounds, according to the study, which was published in the Journal of Medical Internet Research.
“Text messaging has become popular and may be an effective method to simplify tracking of diet and exercise behavior,” Dori Steinberg, who was responsible for this research, said.
Steinberg said, “Text messaging offers several advantages compared to other self-monitoring methods. Unlike web-based diet and exercise diaries, data in a text message can be entered quickly on nearly all cell phone platforms so it is very convenient to receive feedback. Besides, because of the limited number of words used in text messages, it saves time.”
1.According to the study, traditional methods _________.
A. are easier for people to lose weight
B. may cause people to give up losing weight
C. provide brief feedback and tips
D. are easy to track diet and exercise behavior
2.Which is NOT true about text messaging according to Steinberg?
A. It saves time.
B. It saves money.
C. It can be entered quickly.
D. It is easy to receive feedback.
3.What’s the best title for the text?
A. Texting helps keep healthy
B. Texting saves time and money
C. Texting provides brief feedback and tips
D. Texting can help you lose weight
4.What’s Dori Steinberg’s attitude towards text messaging?
A. Unknown. B. Negative.
C. Positive. D. Unconcerned.

Text messaging, or simply “texting”, which allows people to send and receive messages on mobile phones, becomes very popular today.
The advantages of texting are obvious. Texting helps to save money. If you have a few words to greet your families and friends on their birthdays or on some important festivals, sending messages can be cheaper than phone calling. Texting helps to save time. Even if you want to send a message to 100 people, you can do it one second. Texting helps you to “talk” to someone when he is too busy to answer the phone. Texting can also help you to “talk” to someone secretly if you don’t want others to hear what you are talking on the phone. These advantages are so amazing that many people are crazy about it. They hold mobile phones in hands all day long, send dozens of messages each day, and even text while driving or walking.
However, texting has its disadvantages. Junk（垃圾）messages may come into your mobile phone box now and then. When your phone box gets too full, you can’t receive any more messages. You may therefore miss some important information.
What’s more, if you don’t do texting properly, for example texting while driving or walking, it can be dangerous. It can cause injuries and even death. It is reported that about 6,000 people are killed and half a million were injured for this reason each year. In Fort Lee, a small town in New Jersey, USA, three people died because they walked into traffic while texting in 2011. Two researchers at Stony Brook University, New York found that texters are 60% more probably to have an accident than others. When people are texting, they don’t notice other people or things around them. To reduce traffic accidents, no drivers of the USA are now allowed to text while driving. About 32 countries have passed laws forbidding the use of mobile phones while driving.
Texting is a wonderful way of communication. However, only when we use it properly, can we fully enjoy the fun it brings.
1.How many advantages of texting are mentioned in the passage?
A. Three. B. Four. C. Five. D. Six.
2.When your phone box gets full because of junk messages, what will happen?
A. Your phone will break down.
B. Your phone can’t get through.
C. Your phone can’t get messages any more.
D. You lose contact with others.
3.What did the researchers at Stony Brook University find?
A. Texting can cause accidents more easily.
B. Texting while walking can cause death.
C. Calling while driving is easier to have accidents.
D. Many people were killed and injured.
4.According to the passage, which of the following statements is true?
A. Drivers are allowed to text in the USA.
B. Text while walking is dangerous.
C. Junk texting cannot prevent you receiving messages.
D. The advantages of texting are not obvious.
