Everybody hates rats. But in the earthquake places of the world – Japan, Los Angeles, Turkey – rats will soon be man’s new best friends.
What happens after an earthquake? We send in rescue(救援) dogs. Why? Because they can smell people. Dogs save lives. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal. This is sent to a small radio on its back, and then the rescuers follow the radio signals. When the rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “ ‘Robot’ noses don’t work well when there are other smells around. Rats are good at that.” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity.
The “ rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “ It would be fantastic. A rat would get into spaces we couldn’t get to and a rat would get out if it wasn’t safe.” Perhaps for the first time in history, people will be happy to see a rat in a building ( but only after an earthquake, of course.)

A.take the place of man in rescue jobs
B.find the positions of people alive who are trapped in buildings

小题2:The underlined word “that” in Paragraph 4 refers to(所指)  _________

A.the nose made by the rat
B.the rat’s unusual behavior
C.the signal sent by the radio on the rat’s back
D.the smell given off by the person

The rapid growth of Smartphones and electronic tablets(平板电脑)is making the Internet favourite for Americans reading news, a report said.
News consumption online increased 17% last year from the year before. Television news, newspapers, radio and magazines all lost audience last year. For the first time, the number of people who get news online at least three times a week is larger than the number of people who get news from the newspapers. TV news has been the most popular since the 1960s. It has replaced the afternoon newspapers. But now the online news seems to be more popular than the TV news.
People are used to having the Internet available on phones or small tablets. In December, 2010, 41% of Americans said they got most of their news on the Internet, more than double the 17% who said that a year earlier, the report said. In January, 2011, 7% of Americans owned electronic tablets, nearly double what it was three months earlier. It was the fastest-growing new digital technology, ahead of mobile phones when they were introduced. The online ad income was expected to surpass(超过)print newspaper ad income for the first time in 2010.
The news business used to be the intermediary(中介). You needed newspapers and TV stations to reach your customers. In this age of the computer, it’s the software developers that you need.

The world itself is becoming much smaller by using modern traffic and TV, telephone and so on. Life today is much easier than it was hundreds of years ago, but it has also brought new problems. One of the biggest is pollution (污染). Pollution comes in many ways. We see it, smell it, drink it and even hear it.
The more people, the more pollution. Many years ago, the problem was not so serious because there were not so many people. Man is now slowly polluting the whole world.
Air pollution is still the most serious. It’s bad to all living things in the world. Water pollution kills our fish and pollutes our drinking water. Noise pollution makes us become angry more easily.
Many countries are making rules to fight pollution. They stop people from burning coal (煤) in houses and factories in the city.
The pollution of SO2 is now the most dangerous problem of air pollution. It is caused by heavy traffic. It is sure that if there are fewer people driving, there will be less air pollution.

A famous study was done in a school by a professor (教授) from a university. At the start of the school year, the teachers were given the names of five children. They were told that these five were the most excellent students in the class. But the fact was that these students were only average(中等),and they were not the best students at all. Well, guess what? At the end of the year, all the five average students scored among the highest in the class.
  What made these average students change so much to become top students?The only difference was the change in their teachers’ attitude(态度). Because the teachers believed that these five kids were the top students,they expected(期望) more from them. And so these five average students began to believe and expect more from themselves. So they worked harder to do as well as they could.
  Do you know why? If you expect the best from people, they’ll usually want to give you their best. A great leader said, “Treat(对待) a person just how he appears to be on the outside, and you’ll make him even worse. But treat a person like he’s already a success,and you’ll help make him the best he can be.”
  Like the true story of 7-year-old Johnny, his teacher got so angry with him that one day she said,“Johnny,you’re the naughtiest(最顽皮的) boy in this class. I’m sure you’ll never change.” The next year Johnny had a new teacher. And on the first day of class,she met with Johnny after school and said,“Johnny, I’ve heard a lot about you! But do you know that I don’t believe a word of it.” And every day after that, this new teacher treated Johnny as if he was one of the smartest students even when Johnny did naughty things. Later on, Johnny became a school leader. Because that’s the power of our belief(信任) and attitude(态度) toward children.
小题1:The professor started his research(研究)by _______.
A.teaching the five children himself
B.asking the five children to find a new teacher
C.telling the five students to work harder than ever before
D.telling the teacher the five students were the best in the class
小题2:The five average students became top students mainly because of ________.
A.the professor’s study
B.the teachers’ hard work
C.the change in the teachers’ attitude

A.To let us know how good his new teacher was.
B.To show the importance of encouragement.
C.To show that the boy was clever enough.
D.To let us know the famous boy.
小题4:The writer writes the passage mainly by ______.

小题5:What does the passage mainly tell us?

C.Only teachers can make you a top student.
D.Attitude and belief can change a person.
It’s cool, it’s hot, and everyone is doing it. People talk about it often, and friends tell other friends how good they look. Sound like a fashion? In fact, it’s another trend (流行趋势): “blog”. What’s a blog? A blog is a personal online diary. The word “blogger” means a person who writes diaries online.
Many bloggers are teenagers who log (进入) onto websites to discuss anything in their lives. Many of today’s teenagers are not afraid to openly discuss everything in their lives. Teenagers complain about parents and homework. They share diaries, post songs from the latest bands (乐队) and show pictures of theirs. They write their own poems, say something about their girlfriends or boyfriends and complain to each other or offer support. But mostly they just write down what they do every day.
However, many parents are worried about these young bloggers. Parents see the kids talking about how they got drunk last weekend and how they don’t like studying. They are using language that is surprising to their parents. Besides hearing from their friends, teen bloggers also get messages from strangers. Most of the time, it’s older men asking to meet teenage girls. “These strange men are dangerous for my kids. They sometimes teach my kids bad words,” said Cara Cabral, a mother of two.
Many teenagers and young adults know it’s not safe to use blogs on the Internet. They know they are putting information about themselves in a place they can be seen by anyone. But teenagers are unwilling to give up these new communication tools that have become a way of life for many of them.
小题1:The word “it” means ________ in the sentence “People talk about it”.
A.the InternetB.the blogC.the websiteD.talking online
小题2:Parents think it’s dangerous for their kids to use blogs because _______.
A.their kids use a surprising language
B.their kids talk about how they don’t like studying

小题3:Which of the following is NOT true according to (依据) the passage?  
A.It’s easy for teenagers to give up blogging.
B.Many teenagers know it’s not safe to use the blog on the Internet.
C.A blogger’s information about himself can be seen by anyone on the Internet.
D.Most of today’s teenagers aren’t afraid to openly discuss everything in their lives.
