For years , many people would not believe that smoke could attack so many parts of the body in so many ways . Study shows , however , that tobacco isn’t one single thing .  At least 60% of it is gas—20 different kinds of gas . And one of these is the deadly carbon monoxide (CO) (一氧化碳).
In factories , the amount of this gas in the air is measured , and it must be kept under fixed , safe level . But there is 640 times this safe amount in cigarette smoke .
Oxygen is carried through your body by the red blood cells . But this poison gas , CO, will get to the blood cells before the oxygen can . So , if you smoke your blood carries five to ten times more of this deadly gas than is normal . To make up for this , your body must make more red cells .
The oxygen in your blood passes into your tissues(組織). But here again CO makes trouble . It keeps the oxygen from passing into your tissues as fast as it should . Because of this , cigarette country is always about 8000 feet above sea level . Someone who smokes and lives at sea level gets as little oxygen as a nonsmoker at an altitude(高度)of nearly two miles .This happens to everyone who smokes , no matter how old or how young . Anyone who competes in sports can tell you that those who smoke run out of breath more quickly than those who do not .
1.The gas amount in cigarette smoke is______________.
A.640 times higher than the gas safe levels in factories
B.640 times lower than the gas safe levels in factories
C.640 times as much as that in factories
D.a(chǎn)s dangerous as that in factories
2.If you smoke , ______________ .
A.your blood carries more oxygen than is normal
B.your blood carries much more CO than is normal
C.you can have five to ten times of blood than usual
D.your blood will be poisonous
3.Those who smoke______________.
A.a(chǎn)ll live at sea level
B.don’t live at an altitude of two miles
C.breathe as much oxygen as non-smokers
D.only get the same amount of oxygen at the sea level as non-smokers at an altitude of nearly 2 miles
4.Smokers are______________.
A.easily hurt              B.easily excited      C.easily tired         D.healthy

You may be spending far too many of your present moments in efforts to win the approval of others, or in being concerned with some disapproval that you have encountered.We all enjoy applause, compliments(恭維)and praise, and approval in itself is not unhealthy. Approval-seeking is a misleading zone only when it becomes a need rather than a want.
If you want the approval, you are simply happy to have the recognition of the other people. But if you need it, you are going to break down if you don’t get it. That’s when the self-destructive forces move in. Similarly, when approval-seeking becomes a need, you give up a large part of yourself to the “outside person” whose advocacy(擁護)you must have. If they disapprove, then you are immobilized(使喪失機動性)(even in a small way). In such a case, you have chosen to wear yourself——worth on your sleeve for someone to rub or not to rub as they see fit. You feel good inside only if they decide to praise you.
The need for approval of another person is bad enough, but the real trouble comes with the need for the approval of everyone for every act. If you carry around such a need, then you are bound for a great deal of misery and frustration in your life. Moreover, you will be incorporating a wish——washy (軟弱無力的)non-person self-image that will result in the kind of self-rejection.
The need for approval must go! No question makes there. It must be completely got rid of from your life if you are to gain personal fulfillment. Such need is a psychological dead end, with absolutely no benefits to you.
1.Approval-seeking is healthy when________
A.you need the approval
B.you only want the approval
C.you need the approval of everyone for every act
D.you don’t care about the approval
2.The self-destructive forces move in when________
A.you need the approval and you get it
B.you want the approval and you get it    
C.you need the approval but you don’t get it
D.you want the approval but you don’t get it
3.What does the sentence” You hven chosen to wear your self-worth on your sleeve for someone to rub or not to rub as they see fit.” mean?
A.You have decided to give up yourself worth in order to get the approval.
B.You have decided to change yourself worth in order to get the approval.
C.You have decided to show yourself worth to others and allow them to make a judgment.
D.You have decided to put yourself worth in other’s hand and allow them to keep it or hurt it as they like.
4.The need for the approval of everyone for every act will enentually result in________
A.self-rejection        B.real troubles    C.misery     D.frustration
5.What can we infer from the passage?
A.People can benefit from the need of the approval.
B.Both the want and need for approval are unhealthy.
C.The need for the approval is a destructive feeling and people must get rid of it.
D.Since everyone enjoys praise and compliment, approval-seeking is a natural human need.

As you may expect, life in space is much different from life on earth. So of course people need some time to get used to it. How do they live, work and play up there?
Space food keeps getting more like the food we eat at home on the earth. In the past, astronauts could eat only freeze-dried food. But now the space station has water, microwave ovens and fridges. So astronauts can eat more usual kinds of food, like fruit, vegetables and ice cream!
All people in the ISS(國際空間站)have their own rooms. There’s no gravity, so they have to attach themselves to their beds, or they’ll float away! That may seem like a hard way to sleep, but astronauts say that sleeping in space is actually not too bad.
This is more important in space than on Earth. There’s not much gravity in space. Astronauts don’t stand up, sit down or walk in space, so their muscles don’t have to work much. They exercise on bikes and other machines for about two hours every day while they’re in space. In this way, they can still keep strong and healthy when they get back home.
Easy things like brushing your teeth can be hard in space with low gravity. Water doesn’t flow out of a tap, it floats in a bubble(水泡)! Astronauts used a special hose(軟管)to take showers. And when they’re finished, they use a vacuum(真空的)hose to suck the dirty water off of their bodies. How do you go to the toilet in space? They use a special “air toilet”. It uses air, not water, to take everything away.
What do astronauts do when they aren’t working? They read books, play cards, listen to music or send e-mail to their friends and family. Sometimes they just sit and look out the window. Doesn’t sound like much fun? But what if you could see planet Earth out of your window, with a sunset or sunrise every 45 minutes?
1. Which of the following can be the title of this passage?
A. Life In Space.    B. Space Food.      C. Showers In Space.     D. A Visit To Space
2.From this passage we know that _______.
A. astronauts eat quite different food in space from what they eat on the earth
B. astronauts ate only fruit in space in the past
C. astronauts can only eat freeze-dried food now
D. astronauts can only eat fruit and vegetables now
3.Astronauts attach themselves to bed so as to ________.
A. keep themselves warm                                 B. prevent themselves from floating away
C. have a good sleep                                         D. feel better
4.Astronauts have to do exercise for two hours every day because ________.
A. they have nothing to do in space             B. they are told to do so
C. they do so to keep healthy                      D. they do so to prevent them from sleeping
5.From the last paragraph we can guess that ________.
A. the sun moves fast around the earth 
B. the earth circles round the sun very fast
C. the earth is very small
D. the spaceship circles round the earth once every 90 imnutes

Our plan was to drive into Cambridge, catch the 7:34 train to Liverpool Street Station, then to separate and meet again for lunch.We should have arrived at Liverpool at 9:19, but due to a typical London fog, the train had to move along so slowly that it wasn’t until 10:30 that it got there.In spite of our late arrival, Joan, my wife’s sister, decided that she would go to see the Crown Jewels in the Tower of London while we went shopping.It was only after her sister had disappeared into the fog that my wife realized that we hadn’t decided where we should meet for lunch.Since I had our three tickets for the concert in my pocket, this was indeed a problem.There seemed to be nothing we could do except taking a taxi to the Tower of London, and try to find her there.Needless to say, we didn’t find her.
It was now one o’clock, and the concert began at 2:30.“Perhaps she will think of waiting outside the concert hall,” suggested my wife hopefully.By this time the fog was so thick that road traffic had to stop, and the only way to get there was by underground railway.Hand in hand we felt our way along the road to where we thought the nearest station should be.An hour later we were still trying to find it.Just as I was about to lose my temper completely when we met a blind man tapping his way confidently through the fog.With his help we found Tower Hill tube station just fifty yards down the road.
By now it was far too late even to try to get to the concert hall before the performance began at 2:30, so we decided to return to Cambridge.It took seven long hours instead of the usual two to make that journey.Nor were we able to get any food and drink on the train.Tired and hungry we finally reached home at ten, opening the door to the sound of the telephone bell.It was Joan; she had seen the Crown Jewels, had managed to get another ticket for concert, and had had a wonderful dinner at a restaurant near the hotel where she decided to stay for the night.Now she was ringing to discover whether we had had an equally successful day.
1.Why was Joan separated from her sister and her brother-in-law?
A.they could not see each other because of the fog.
B.Joan had not seen Crown Jewels.
C.They planned to do different things until lunch time.

2.What did the writer plan to do in the afternoon?

A.They lost their way in the fog
B.they forgot to make necessary arrangement

D.the couple couldn’t find the underground station
4.It’s quite clear that for Joan the trip to London had been ________.

閱讀下列短文,從每題所給的四個選項中,選出最佳答案
A couple of years ago, I received a $ 600 insurance dividend (保險股息).Sitting at the kitchen table, my wife and I discussed what we might do with the money. I realized now that the refrigerator overheard our talk. The very next day it went wrong. The repairman told us we needed a new unit. Cost:$600. Not long after that, we got a refund(賠償金)from the shop, enough to pay for a trip to Mexico. “I’ve something to tell you,” I said to my wife in a low voice. “How about the living-room?” she suggested. I remembered the color TV set was there. “No, not there. Let’s go out.” I showed her the check as we stood on the driveway. We held each other excitedly and hardly noticed the rain. My car was parked within5 meters. I didn’t think anything about it at the time. As I started for the airport the next day, the car began making strange sounds. Changing the engine cost about $ 1, 000.
Then I looked through our financial records. I discovered that during the last ten years we spent all our “found money” repairing a hot water heater, a television and a stove.
I never mention money in front of our mechanical equipment. But if this article is published and I am paid for, the word processor(文字信息處理機)is going to go for sure. It’ll know.

C. The TV set              D. The engine of the car

It is easy to understand the way a culture approaches disagreements by looking at the communication styles in that culture. In societies where open discussion is encouraged, conflict is much more common and accepted. On the other hand, cultures that strive to reduce conflicts and maintain harmony do not see such interaction appropriate, particularly in the workplace.
In Australia, Great Britain, and the United States, for example, disagreements are considered a natural part of communication. People in these countries typically have open and honest discussions, even if people’s differences of opinion lead to confrontation(對抗,對立). In business setting, this may mean debating with a colleague or a supervisor over the approach to a task. Or, co-workers might have a discussion about whether an agenda(議程)item during a meeting is suitable or not. Conflict is not necessarily negative ,though. And many people feel that debating an issue is as rewarding as resolving it. Successful conflict resolution(沖突解決) is also seen as a valuable skill, most people at the management level are expected to be very good at handling conflicts that arise in the workplace.
The Asian style of communication is quite different. In almost parts of eastern Asia, individuals present their ideas and then wait for others to do the same. They prefer to seek agreement from a group without rejecting another’s opinions out loud. In business meetings, subordinates (下級) will hardly disagree openly with their supervisor. This shows respect for supervisor, and it reflects the cultural importance placed on politeness and building harmony and trust.
1. The best title for this passage is ______.
A. Approaching Disagreements                    B. Differences of Opinion
C. Culture and Communication                    D. Conflict Resolution
2. In Australia, people would consider disagreement______.
A. a negative part of communication             B. necessary in their communication
C. normal and beneficial                            D. Unimportant in communication
3. Which of the following is true according to the author?
A. Subordinates in the USA don’t try to show their respect in the supervisors.
B. Asian people at management level are not good at handling conflicts.
C. People in Asia always try to avoid conflicts.
D. People in some western countries like to have conflicts.
4. What does the underlined word “harmony” probably mean?
A. Difference           B. Agreement     C. Respects        D. Communication

Divorce is bad for environment
US researchers raised a new theory on Monday: divorce is bad for the environment.
The global trend toward higher divorce rates has created more households with fewer People,
scientists at Michigan State University reported in the Proceedings of the National Academy of
Sciences.
More households means more houses,fuel and water are Heeded for them,the researchers  wrote.“Globally,the number of households is increasing much faster than the number ofpeople,”said co-author “Jack” Liu in a telephone interview. “Even in regions with declining populationn, we see substantial increase in the number of households. Divorce is the main reason for reducingthe number of people in a household,” he said.
The average divorced person’s household is about 40 to 50 percent smaller than the average married person’s household, Liu said. But whether there are three or six people in a house ,the amount of fuel needed to heat them is about the same. In the United States, divorced households used 74 billion kilowatt—hours of electricity and 2.850 trillion liters of water in 2005, half of which could have been saved if households had stayed the same size as when they were married.
In the United States and 11 other countries between 1998 and 2002, if divorced households had combined to have the same average household size as married households, there could have been 7.4 million fewer households.
The number of divorced households in those countries ranged from 40,000 in Costa Rica to
almost 16 million in the United States around 2000. The number of rooms per person in divorced households was 33 percent to 95 percent greater than in married households.
“If you really want to get divorced, maybe you can remarry with somebody else, or live together with somebody else you like”, Liu said.
1. In America when the number of households is_________, the number of people in a house is__________.
A. increasing, decreasing               B. decreasing, increasing
C. increasing, increasing                   D. decreasing, decreasing
2. What does the word “substantial” in the third paragraph mean?
A. Great        B. Little           C. Sudden                D. Timely
3. How much electricity would have been saved without so many people getting divorced in America in 2005?
A. 7.4 million kilowatt-hours                 B. 16 million kilowatt-hours
C. 37 billion kilowatt-hours             D. about 30 billion kilowatt-hours
4. The last paragraph is the writer’s_________for people.

Because of the development of agriculture, the area of land affected by sand has gradually increased. During the 1950s and 1960s the land affected by sand expanded on average into 1,600 square kilometers per year. By the 1990s, the area had reached 2,500 square kilometers per year.  This kind of situation is particularly serious in many regions upwind(逆風(fēng)的) from Beijing. Fengning City in Hebei Province and Duolun City in Inner Mongolia lie to the north of Beijing, and in the last 50 years the population of these two cities has grown by 2 to 3 times. In order to obtain more resources, the inhabitants have been busy with  heavy farming, tree-cutting and keeping animals. The result is that the soil which has sustained damage, and the sand layer below the earth is now exposed on the ground and the ground is rapidly being controlled by the spread of sand.
China has already noticed this problem, and has take measures to save the land. Nowadays, some land used for farming has returned to forestland and grassland. The Chinese government announced that it would invest more than RMB 600,000,000 to control Beijing’s sandstorms in the coming years. Only by decreasing the damage caused by man and restoring the natural environment will it be possible to well control the sources of the sand and dust. We hope in the not-distant future, we will solve the problem successfully and effectively.  
63. Compared with 50s and 60s, the land affected by sand increased by _____ square kilometers by the 1990s.
A. 1,600        B. 2,500         C. 900          D. 1,100
