Last week, I bought an alarm system for about $ 450. It consisted of a control unit with three small units. I put the control unit in the sitting-room and fastened the other units by the front door, back door and living-room windows. The instructions told us to choose three numbers, so we chose 4, 9 and 1, the last three numbers of our telephone number.
Now I must explain how the alarm works:
l There is a power siren(警報(bào)器) in the control unit. It makes a very loud noise.
2 Each of the small units sends out beams or rays in different directions. If anything moves, it breaks a beam. This sends a signal to the control unit. The siren makes a noise which you can hear 50 meters away.
3. When we go to bed, I press the three buttons numbered 4, 9 and 1. Then we have 30 seconds to get out of the room before the alarm starts to work.
That night I slept soundly because I was sure that no burglar(夜賊) could get into our house. However, at about 2:10 a. m., I woke up and heard the siren. “There must be a burglar in the house,” Mary said. “What shall we do?”“I’ll go and see who’s there,” I said. “Stay here. Don’t make a noise.”I went downstairs quietly. When I reached the living-room, I switched on my torch and looked round the room. Then I turned the light on. I switched the siren off and searched the rooms downstairs. There was nothing wrong except that the back door was unlocked. I locked it, reset the alarm and went back to bed. About an hour later, the alarm started again. I jumped out of bed, fell over a chair in the dark and bumped into the bedroom door. Mary woke up and started hitting me with a torch. “Hey! Wait a minute!” I whispered. “It’s only me. I’m going downstairs to see what’s wrong.”I went down into the living-room and listened for a moment. The only sound I could hear was the siren. I turned on the light and then switched the siren off. As I did so, I glanced across at the curtains in front of the windows. I saw a house lizard (a kind of small animal) disappear behind the curtains.“Oh!” I said to myself. “That’s our burglar. ”When the lizard moved, it started the siren. I guessed that the alarm had been made in Europe, where there are no house lizards. Well. I won’t finish this story but if you want an alarm system free of charge, let me know. I’ll send you ours. We bought a dog this morning. It knows the difference between a lizard and a burglar.

Without most people realizing it, there has been a revolution in office work over the last ten years. Before that time, large computers were only used by large, rich companies that could afford the investment. With the advancement of technology, small computers have come onto the market, which are capable of doing the work that used to be done by much larger and expensive computers, so now most smaller companies can use them
The main development in small computers has been in the field of word processors（處理器）, or WPS as they are often called. 60% of British offices are now estimated to have a word processor and this percentage is growing fast.
There are many advantages in using a word processor for both secretary and manager. The secretary is freed from a lot of daily work, such as re-typing letters and storing papers. He or she can use this time to do other more interesting work for the boss. From a manager’s point of view, secretarial time is being made better use of and money can be saved by doing daily jobs automatically outside office hours.
But is it all good? If a lot of daily secretarial work can be done automatically, surely this will mean that fewer secretaries will be needed. Another worry is the increasing medical problems related to work with visual display units（顯示器）. The case of a slow loss of sight among people using word processors seems to have risen greatly. It is also feared that if a woman works at a VDU for long hours, the unborn child in her body might be killed. Safety screens to put over a VDU have been invented but few companies in England bother to buy them.
Whatever the arguments for and against word processor, they are a key feature of this revolution in office practice.
小題1:Ten years ago, smaller companies did not use large computers because_________.
A．these companies had not enough money to buy such expensive computers
B．these computers could not do the work that small computers can do today
C．these computers did not come onto the market
D．these companies did not need to use this new technology
小題2:According to the writer, the main feature of the revolution in office work over the last ten years is __________.
A．the saving of time and money
B．the use of computers in small companies
C．the wide use of word processors
D．the decreasing number of secretaries
小題3:It is implied in the passage that with the use of word processors _________.
A．some secretaries will lose their jobs
B．daily jobs can be done automatically outside office hours
C．medical problems related to work with a VDU have increased greatly
D．the British companies will make less money
小題4:Which of the following statements is NOT true?
A．There are both advantages and disadvantages in using a word processor.
B．The British companies care much for the health of the people using word processors.
C．The technology in the field of computers has been greatly advanced over the last ten years.
D．Using word processors, secretaries can get more time to do more interesting work for their bosses.
小題5:It can be concluded from the passage that ________.
A．safety screens are of poor quality
B．working at a VDU for a long time is good for one’s health
C．more and more British offices will use word processors
D．British companies will need fewer and fewer managers

Some expressions in English can be really puzzling. Have a look at the following to see how it challenges your brainpower.
Homeric laughter
The "Homer" in this expression is the Greek poet. People laugh differently. Some laugh silently, while others tend to laugh loudly. "Homeric laughter" refers to laughter of the latter kind. It is at times uncontrollable, and the entire body shakes during the process. This kind of laughter is called Homeric laughter because this is how the gods laughed in Homer's classics.
A three-ring circus
When you refer to a situation as being a three-ring circus, you are saying that it is a situation of complete confusion. There are so many activities taking place all together that they leave you confused or annoyed. The expression comes from the world of entertainment — the circus. The area where the artists perform their acts is called the "ring". In the past, some of the circuses were so grand that they had three acts taking place simultaneously in three different "rings". The audience had to decide which "ring" they wanted to focus on.
In the swim (of things)
When someone is in the swim of things, the individual is actively participating in the things happening around him, as in "I've been ill, but soon I’ll be back in the swim of thing." In the world of fishing, fishermen use the word "swim" to refer to the section of the lake/river where fish can be found in plenty. So, if you are a fisherman and wish to catch a lot offish, where would you be? You would be "in the swim".
Chickens have come home to roost
The word "roost" refers to the place where birds rest. It could be anything — the branch of a tree, a henhouse, etc. The expression is normally used to mean that the bad things that someone did in the past have come back to bite or upset the individual. In other words, one has to face the consequences of the deeds done in the past. The original form of this 700-year-old expression was "curses are like chickens; they always come home to roost".
小題1:Which of the following can best describe the picture?
A．Homeric laughterB．A three-ring circus
C．In the swim (of things)D．Chickens have come home to roost
小題2:What does the underlined word "simultaneously'(Paragraph 3) mean?
A．At the same time.B．Step by step.
C．All of a sudden.D．One after another.
小題3:lf you want to know more about such expressions, which website will you probably visit?
A．www.chinadaily.com.cn/sports/China.html
B．www.chinadaily.com.cn/world/university.html
C．www.chinadaily.com.cn/culuture/language.html
D．www.chinadaily.com.cn/entertainment/fashion.html

Parents whose children show a special interest in a particular sport feel it very difficult to make a decision about their children’s careers. Should they allow their children to train to become top sports men and women? For many children it means starting school work very young, and going out with friends and other interests have to take a second place. It’s very difficult to explain to a young child why he or she has to train five hours a day, even at the weekend, when most of his or her friends are playing.?
Another problem is of course money. In many countries money for training is available from government for the very best young sportsmen and women. If this help can not be given, it means that it is the parents who have to find the time and the money to support their child’s development—and sports clothes, transport to competitions, special equipment, etc. can all be very expensive.?  
Many parents are worried that it is dangerous to start serious training in a sport at an early age. Some doctors agree that young muscles may be damaged by training before they are properly developed. Professional trainers, however, believe that it is only by training young that you can reach the top as a successful sports person. It is clear that very few people do reach the top, and both parents and children should be prepared for failure even after many years of training.?
小題1:This article is most probably taken from________.?
A．a(chǎn) letter
B．a(chǎn)n advertisement?
C．a(chǎn) personal diary
D．a(chǎn) newspaper article?
小題2:According to the passage, parents whose children show a special interest in a sport _______.
A．feel uncertain if they should let their children train to be sports men or women
B．try to get financial（財(cái)務(wù)的）support from the government for their children’s training
C．have to get medical advice from doctors about training methods?
D．prefer their children to be trained as young as possible
小題3:The underlined phrase“to take a second place”means_________.?
A．to repeat the activities at some other place?
B．to become less important?
C．a(chǎn)ll things considered, they are of poor quality?
D．to happen again

Most American students have to say goodbye to fancy (高檔的) fruits these days. In school restaurants across the country, cheaper fruits like apples and oranges have taken their place.
“People are afraid to spend now.” said Linda Morrow, who owns a shoe and handbag store. “They don’t know what the future will bring”. During the financial crisis (金融危機(jī)), several of the country’s biggest banks have been forced to sell or close. This has made lots of Americans afraid to buy expensive things.
The crisis began last year. Experts (專家) think it was because US banks lend money too easily. Last year a lot of people and companies, who borrowed money, found themselves unable to pay it back. This left the banks, as well as the people who put their money in the banks, without money. Since the banks borrowed money between themselves and even across borders (國界), the whole world was in trouble.
This month the US government agreed on a $700 billion plan to try to save the financial market. But no one is sure whether it will help or not. Last week presidents from 20 countries promised to work together to find a way out of the money trouble.
小題1:This passage is probably taken from ___________.
A．a(chǎn) story bookB．a(chǎn) novelC．a(chǎn) newspaperD．a(chǎn)n advertisement
小題2:Why are people in the US afraid to spend?
A．Because they think it’s unnecessary
B．Because they don’t have the habit of spending money
C．Because they worry about their future
D．Because they don’t have any money
小題3:From the passage, we still don’t know ________.
A．when the financial crisis began
B．when the financial crisis will end
C．why some of the US banks closed
D．whether the crisis has spread to other countries
小題4:The best title for the passage is ___________.
A．Ways to Save Money

Facial expressions carry meaning that is determined by situations and relationships. For example, in American culture the smile is in general an expression of pleasure. Yet it also has other uses. A woman’s smile at a police officer does not carry the same meaning as the smile she gives to a young child. A smile may show love or politeness. It can also hide true feelings. For example, many people in Russia consider smiling at strangers in public to be unusual and even improper. Yet many Americans smile freely at strangers in public places (although this is less common in big cities). Some Russians believe that Americans smile in the wrong places; some Americans believe that Russians don’t smile enough. In Southeast Asian culture, a smile is frequently used to cover painful feelings. Vietnamese people may tell a sad story but end the story with a smile.
Our faces show emotions (情感), but we should not attempt（嘗試）to “read” people from another culture as we would “read” someone from our own culture. The fact that members of one culture do not express their emotions as openly as do members of another does not mean that they do not experience emotions. Rather, there are cultural differences in the amount of facial expressions permitted. For example, in public and in formal situations many Japanese do not show their emotions as freely as Americans do. When with friends, Japanese and Americans seem to show their emotions similarly.
It is difficult to conclude about Americans and facial expressiveness because of personal and cultural differences in the United States. People from certain cultural backgrounds in the United States seem to be more facially expressive than others. The key is to try not to judge people whose ways of showing emotion are different. If we judge according to our own cultural habits, we may make the mistake of “reading” the other person incorrectly.
小題1:What does the smile usually mean in the U.S.?
A．Love.B．Politeness.C．Joy. D．Thankfulness.
小題2:The author mentions the smile of the Vietnamese to prove that smile can ___ .
A．show friendliness to strangersB．be used to hide true feelings
C．be used in the wrong placesD．show personal habits
小題3:What should we do before attempting to “read” people?
A．Learn about their relations with others.
B．Understand their cultural backgrounds.
C．Find out about their past experience.
D．Figure out what they will do next.
小題4:What would be the best title for the test?
A．Cultural Differences B．Smiles and Relationship
C．Facial ExpressivenessD．Habits and Emotions

A group of teenagers: they laugh and talk over each other, dance and make faces — you wouldn’t believe they had just played on the same stage as famous American singers Kid Cudi and Eminem.
These seven kids, all under the age of 20, are members of the band Kids These Days (KTD).
Fresh out of high school, the band already has done things that most teens couldn’t even imagine. They played at festivals including the recent SXSW in Austin and Lollapalooza in their hometown, Chicago, to crowds of loyal fans.
KTD uses a mix of hip-hop, jazz, blues and classic rock to make a sound of their own.
“KTD simply mixes most, if not all of my favourite music styles,” said Kamia Jones, as Chicago high school student.“I like that they aren’t afraid to be different and that their music is real and speaks to the soul.”
The band formed two years ago. Now, as well as local fans, they are becoming popular around the world. Their facebook page is filled with supportive posts from admirers from California to Tokyo.
“It’s really strange to me that people from London, Australia and Russia... They have heard
of us and they like our music because it’s really cool feeling,” says Marcie Stewart, who plays keyboard for the band.
Despite their recent fame, KTD is a group of normal teenagers and they remain very close to one another. While talking to the reporters, they dance and make fun of each other.
When asked what advice they would give to other teen musicians, Greg Landfair, KTD’s drummer, said, “Keep your heart in it. Never lose the music and what you are doing, because that’s what you’re here for. Let the music always be first.”
小題1:KTD’s music is popular among teenagers mainly because ________.
A．it is about the strange life of teenagers
B．it mixes many music styles teenagers love into their music

小題2:What do we know about KTD?
