Everybody hates rats. But in the earthquake capitals 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 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(信號(hào)).This is sent to a small radio on its back, and then the rescuers follow the radio signals. When 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, “Robots’ 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 could 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’s rescue jobs

任務(wù)型閱讀(每小題1分, 滿分10分)
Nowadays, more and more people are using email, but sometimes we use it too much or use it inappropriately. To get the most out of email we need to use it carefully and sensibly. These are some simple tips to help you make a better use of email.
It is good to have separate email accounts for separate purposes. For example, you may have one for business and one for social activities. This means you can check the personal email in the evening without having to think about business. If you see an important message from your boss, it could ruin your weekend or evening. After all, most people want to relax themselves and get away from work at the end of the day. Don't allow email to make you a slave to work. Some people feel it is inconvenient to check 2 different email accounts. But the relative inconvenience is easily outweighed by the benefits.
Many people ignore the title of an email. If the subject changes don’t keep using an old “re: irrelevant title.” A good title increases the chance that people will actually read your email rather than just leaving it for later. A bad title may even get deleted as spam.(垃圾郵件)
Emails can be brief and to the point. If the message has to be long, make sure it is broken up into different sections, which are easy to read. But, generally you should aim to keep it less than 5 sentences. This is good for both the writer and the reader.
If somebody sends some important documents, files or message, make sure you, at least, acknowledge their receipt(接收). Otherwise they may be uncertain that you’ve got them. It doesn't have to be long; it can be quite short.
If you find yourself sending similar answers to many people, write a draft message and save it in your drafts folder (or write it in Word). You can use this standard response for emailing many people. Don’t forget to personalize it by adding their names.
Having a signature looks professional and saves typing the same information. Remember people may wish to contact you through other ways. So make sure you have a phone number and address in your email. If relevant, add any qualifications and websites that you have. This gives people a chance to find out more about you.

The film “Avatar” has received great popularity around the world. It turned out to be a great success. The film got $1 billion in ticket sales in a very short time. The story in the film happens on an alien planet called Pandora where many strange species live. Among the planet’s inhabitants(居民,棲息動(dòng)物),the one that has the most similarities with humans is the Na’vi, and it is the struggle between the Ma’vi and human invaders(入侵者) that forms the story of the film.
As to the factors(因素) leading to the film’s success, many think that the entertaining feast(盛宴) for the eyes and the wonderful story shouldn’t be forgotten, but the new language invented especially for the film which provides audiences with a new experience also plays an important part.
In order to increase the truthfulness of an alien race(外星人), the film’s director James Cameron asked an expert in languages from the University of Southern California to invent a language for the Na’vi. Professor Paul Frommer combined the languages spoken among Indians, Africans and mid-Asians and worked with James Caneron for four years to create the Na’vi language based on the original 30 words that the director had already come up with.
According to Professor Frommer, the most important characteristic of the Na’vi language is that it could be pronounced. “This is an alien language but obviously it has to be spoken by human actors and actresses,” Professor Frommer told the BBC, “it has to sound natural and it should make human beings comfortable when using it.”
The language has a vocabulary of around 1000 words but Progessor Formmer hopes to enlarge the vocabulary in possible follow-ups to the film and in video games. The professor hopes that one day his creation will be as successful as the Klingon alien language from the “Star Trek”films. “There’s a translation of Hamlet into Klingon and it has received great popularity among the audiences,” says Professor Frommer,“if anything like this happens to the Na’vi language, I’d be very happy.”
1. What do we know about“Avatar” from this passage?
A. The story in it is a moving love story.    
B. It brings the producer $1 billion in total.
C. The story in it happens on an alien planet.
D. It talks about humans and aliens’ friendship.
2. The director of “Avatar” James Cameron had a language invented for the Na’vi to     
A. make the film a whole mystery          B. make the Na’vi more believable
C. make the Na’vi different from humans    D. make the film have specific characteristics
3. Who first created the basic words of the Na’vi language?
A. Paul Frommer.        B. An Indian.    C. James Cameron     D. Hamlet.
4. The important feature of the Na’vi language is that      
A. it can be spoken by humans         B. it has just 30 original words
C. it has a vocabulary of 1000 words.    D. it is like the Klingon alien language
5. We can infer from the passage that       
A. James Cameron will produce follow-ups to “Avatar”
B. the Na’vi language is another kind of the Klingon language
C. the director believes the Na’vi language will be popular
D. Paul Frommer hopes to add new words to the Na’vi language

Have you ever posted letters to your friends or parents? If so, you must have put stamps on the letters before you sent them. But, how did people receive letters before stamps were invented, and who came up with the idea of using stamps?
In the past, stamps and envelopes were not used. When people wanted to send a letter, they would close the paper with a seal(封。. The person who got the letter had to pay for it. Because costs at that time were very high, most people refused to accept letters. In fact, the sender would often place secret marks on the outside of the letter. The person who was sent the letter would read the secret message. Then, they would refuse to accept the letter and did not have to pay for it.
In Britain, Sir Rowland Hill introduced the “Post Office Reforms” in 1837. He decided that letters could go to any place in the country for a penny even if the letter had to go far away. The cost was to be paid by the sender of the letter. Payment was recorded by placing a small piece of coloured paper on the letter, the stamp! On May 6,1840, the first stamp called the “Penny Black” was born. Because the stamp was printed in black, the stamp became known as the “Penny Black”. This is now the world’s most famous stamp. This new system spread fast.

第一節(jié):(共15小題,每題2分,共30分)
閱讀下面四篇短文,從四個(gè)選項(xiàng)(A、B、C、D)中,選出最佳選項(xiàng),并在答題卡上將該項(xiàng)涂黑。
A
Recently, a professor of philosophy in the United States has written a book called Money and the Meaning of Life. He has discovered that how we deal with money in our day-to-day life has more meaning than we usually think. One of the exercises he asked his students to do is to keep record of every penny they spend for a week. From the way they spend their money, they can see what they really value in life.
He says our relation with others often becomes clearly defined when money enters the picture. You might have wonderful friendship with somebody and you think that you are a very good friend. But you will know him only when you ask him to lend you some money. If he does, it brings something to the relationship that seems stronger than ever before. Or it can suddenly weaken the relationship if he doesn’t. This person may say that he has a certain feeling, but if it is not carried out in the money world, there is something less real about it.
Since money is so important to us, we consider those who possess a lot of it to be very important. The author interviewed some millionaires in researching his book.
Question: What is the most surprising thing you have discovered abotrt being rich, because you are a self-made man?
Answer: The most surprising thing is how people give me so much respect. I am nothing. I do not know much. All I am is rich.
People just have an idea of making more and more money, but what is it for? How much do I need for any given purposes in my life? In his book, the professor uncovered an important need in modern society: to bring back the idea that money is an instrument rather than the end. Money plays an important role in the material world, but expecting money to bring happiness may be missing the meaning of life.
56. The author seems to believe that asking your friend to lend you some money_______.
A. is a good way to test your friendship     B. will do harm to your friendship
C. will strengthen your friendship           D. is a good way to break off your friendship
57. What can we learn about the millionaire from his answer in the interview?
A. He does not feel that he is well educated.
B. He does not think that he is a very important person.
C. He doesn’t think that being rich is worth so much attention.
D. He does not consider himself to be very successful
58. What does the American professor of philosophy want to explain in his book?
A. Money is an end.         B. Money is a means.
C. Money is everything.      D. Money is unimportant.
59. Which of the following might the author disagree with?
A. Money is important in modern society.
B. The meaning of life does not completely lie in money.
C. Wealth will surely bring the owner happiness.
D. Happiness is not necessarily the result of wealth.
