There is very simple way of measuring the height of a water-tower, which we cannot measure by climbing.
Suppose, for example, that we wish to find out the height of the water-tower, AB, in a factory. We first of all go to where the water-tower is standing and measure a distance of, say, 25 feet from it. Then we take a stick, and stand it in the ground at the spot we have just marked.
Let us suppose the stick we are using is 4 feet in height. We now walk farther away from the water –tower in the same straight line as when we measured off the distance of 25 feet. We go from the water-tower until we come to point E, where with our head on the ground, we see the top of the stick and the top of the water-tower in the same height line---that is, the top of the stick just covers the highest part of the water-tower. Every schoolboy can work out the height of the water-tower now.
Suppose that the line CE is five feet. We know that the stick is 4 feet high and the distance BE is 30 feet. Thus, 5 is to 4 as 30 is to AB.
【小題1】If we want to know how high a tall tree is,_______.
A. we have to climb up the tree
B. we have no way out
C. we must cut down the tree
D we needn’t climb up the tree
【小題2】 According to the passage, which of the following is correct?

【小題3】It is clear from this that the problem can be settled by _________.

A.a(chǎn) child
B.the boy who has little schooling
C.everyone
D.a(chǎn) girl at middle school
【小題4】To measure a water-tower in this way, _________.
A.no tool is needed
B.Besides a stick, tape-measure (卷尺) or at least a ruler is necessary.
C.we have to use nothing but a stick
D.we have to prepare a set of expensive tools

Exercise is one of the few factors with a positive role in long-term control of body weight. Unfortunately, that message has not gotten through to the average American, who would rather try switching to "light" beer and low-calorie bread than increase physical efforts. The Centers for Disease Control, for example, found that fewer than one-fourth of overweight adults who were trying to lose weight said they were combining exercise with their diet.
In rejecting exercise, some people may be discouraged too much by caloric-expenditure(熱量消耗)charts; for example, one would have to quickly walk hard three miles just to work off the 275 calories in one delicious Danish pastry(小甜餅). Even exercise professionals accept half a point here. "Exercise by itself is a very tough way to lose weight," says York Onnen, program director of the President's Council on Physical Fitness and Sports.
Still, exercise's supporting role in weight reduction is vital. A study at the Boston University Medical Center of overweight police officers and other public employees confirmed that those who dieted without exercise regained almost all their old weight, while those who worked exercise into their daily routine maintained their new weight.
If you have been sedentary (極少活動的) and decide to start walking one mile a day, the added exercise could burn an extra 100 calories daily. In a year's time, assuming no increase in food intake, you could lose ten pounds. By increasing the distance of your walks gradually and making other dietary adjustments, you may lose even more weight.
【小題1】What is said about the average American in the passage?

A.They tend to hate "light" beer and low-calorie bread.
B.They usually ignore the effect of exercise on losing weight.
C.Most of them were combining exercise with their diet.
D.They know the actors that play a positive role in keeping down body weight.
【小題2】"Even exercise professionals accept half a point here" means "They          ".
A.a(chǎn)gree that the calories in a small piece of pastry can be easy to work off by exercise
B.partially believe diet plays a supporting role in weight reduction
C.a(chǎn)re not fully convinced that dieting can help maintain one's new weight
D.a(chǎn)re not sufficiently informed of the positive role of exercise in losing weight
【小題3】What was confirmed by the Boston University Medical Center's study?
A.Controlling one's calorie intake is more important than doing exercise.
B.Even occasional exercise can help reduce weight.
C.Weight reduction is impossible without exercise.
D.One could lose ten pounds in a year's time if there's no increase in food intake.
【小題4】What is the author's purpose in writing this article?
A.To stress the importance of maintaining proper weight.
B.To support the statement made by York Onnen.
C.To show the most effective way to lose weight.
D.To introduce the study of the Boston University Medical Center.

It is hardly surprising that clothing manufacturers (生產(chǎn)商)follow certain uniform standards for various features(特征)of clothes. What seems strange, however, is that the standard adopted for women is the opposite of the one for men. Take a look at the way your clothes button. Men’s clothes tend to button from the right, and women’s from the left. Considering most of the world’s population--men and women are right-handed, the men’s standard would appear to make more sense for women. So why do women’s clothes button from the left?
History really seems to matter here. Button first appeared only on the clothes of the rich in the 17th century, when rich women were dressed by servants. For the mostly right-handed servants, having women’s shirts button from the left would be easier. On the other hand, having men’s shirts button form the right made sense, too. Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt.
Today women are seldom dressed by servants, but buttoning from the left is still the standard for them. Is it interesting? Actually, a standard, once set, resists change. At a time when all women’s shirts buttoned from the left, it would have been risky for any single manufacture to offer women’s shirts that buttoned the right. After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch. Besides from the right, since anyone who noticed that would believe they were wearing men’s shirts.
【小題1】What is surprising about the standard of the clothing industry?

A.It has been followed by the industry for over 400 years.
B.It is different for men’s clothing and women’s.
C.It works better with men than with women.
D.It fails to consider right-handed people.
【小題2】What do we know about the rich men in the 17th century?
A.They tended to wear clothes without buttons.
B.They were interested in the historical matters.
C.They were mostly dressed by servants.
D.They drew their swords from the left.
【小題3】Women’s clothes still button from the left today because        .
A.a(chǎn)dopting men’s style is improper for women
B.manufacturers should follow standards
C.modern women dress themselves
D.customs are hard to change
【小題4】The passage is mainly developed by          .
A.a(chǎn)nalyzing cause B.making comparisons

For as long as humans have lived on the earth, they have made use of various forms of communication. Generally, this expression of thoughts and feelings has been in the form of oral speech. When there is a spoken language problem, communication can be carried out through sign language, in which gestures stand for letters, words, and ideas. Tourists and people unable to hear or speak have often had to turn to this form of expression. When gestures describe words or ideas, they can often be used internationally. When used for spelling words however, where each gesture stands for a single letter, people must share the same written language.
Body language sends ideas or thoughts by certain actions, either meaningfully or not. A wink can be a way of showing that the person is only joking. A nod means agreement, while shaking the head indicates disagreement.
Other forms of language can be found in Braille (a reading system of raised dots read with the fingertips used by the blind), signal flags, Morse code, and smoke signals. Road maps and picture signs also guide and warn people. While language is the most common form of communication, other systems and techniques also express human thoughts and feelings.
【小題1】Which of the following ways can not be used as a form of communication?

A.oral speech B.sign language C.body language D.thought
【小題2】What does the author mainly want to say?  
A.People can communicate in many different ways.
B.Everybody uses only one form of communication.

A serious problem for today's society is who should be responsible for our elderly and how to improve their lives. It is not only a financial problem but also a question of the system we want for our society. I would like to suggest several possible solutions to this problem.
First, employers should take the responsibility for their retired employees. To make this possible, a percentage of profits should be set aside for this purpose. But when a company must take life-long responsibility for its employees, it may suffer from a commercial disadvantage due to higher employee costs.
Another way of solving the problem is to return the responsibility to the individual. This means each person must save during his working years to pay for his years of retirement. This does not seem a very fair model since some people have enough trouble paying for their daily life without trying to earn extra to cover their retirement years. This means the government might have to step in to care for the poor.
In addition, the government could take responsibility for the care of the elderly. This could be financed through government taxes to increase the level of pensions. Furthermore, some institutions should be created for senior citizens, which can help provide a comfortable life for them. Unfortunately, as the present situation in our country shows, this is not a truly viable answer. The government can seldom afford to care for the elderly, particularly when it is busy trying to care for the young.
One further solution is that the government or social organizations establish some working places especially for the elderly where they are independent.
To sum up, all these options have advantages and disadvantages. Therefore, it is reasonable to expect that some combination of these options may be needed to provide the care we hope to give to our elderly generations.
【小題1】What is the passage mainly about?

A.The problems faced by the old in society.
B.Why we should take responsibility for the old.
C.How we can improve the lives of the old.
D.Where the old can go to get their pensions.
【小題2】The underlined word "viable" most probably means"       ".
A.impossible B.practical C.useful D.important
【小題3】What is the writer's main purpose in writing this article?
A.To point out the need for government support for old people.
B.To make general readers aware of the problems of retired people.
C.To discuss some possible solutions to an important social problem.
D.To instruct retired people on how they can have a happier life.
【小題4】The text is most likely to be found in a book about____.  
A.social science B.historical events
C.political problem D.political systems

Since we are social beings, the quality of our lives depends in large measure on our interpersonal relationships.One strength of the human condition is our tendency to give and receive support from one another under stressful circumstances.Social support consists of the exchange of resources among people based on their interpersonal ties.Those of us with strong support systems appear better able to deal with major life changes and daily difficulties.People with strong social ties live longer and have better health than those without such ties.Studies over a range of illnesses, from depression to heart disease, show that the presence of social support helps people protect themselves from illness, and the absence of such support makes poor health more likely.
Social support cushions stress in a number of ways.First, friends, relatives and coworkers may let us know that they value us.Our self respect is strengthened when we feel accepted by others despite our faults and difficulties.Second, other people often provide us with informational support.They help us to explain and understand our problems and find solutions to them.Third, we typically find social companionship supportive.Engaging in leisure time activities with others helps us to meet our social needs while at the same time distract(轉(zhuǎn)移…注意力)us from our worries and troubles.Finally, other people may give us important support—financial aid, material resources, and needed services—that reduces stress by helping us solve and deal with our problems.

From now on, never spend your precious time thinking of reasons for your failures and shortcomings. Instead, realize that the seeds of success were planted within you when you were born. Only you have the power to make those seeds grow.
The seeds, and the power to grow them, are contained in the best machine ever created: the human mind. Success is a choice and not a chance. You were born a winner. You can be a success if only you make the right choice.
You cannot be successful without first developing your self-esteem(自尊). Your level of self-esteem is always based on the degree of control that you are able to have over yourself, and thus over your life. People with low self-esteem are people who do not believe that they have any power, or responsibility for their lives. They are leaves tossed(搖擺) by the winds of chance blown about with any sudden change in the weather.
You can control your life only to the degree that you believe that you are responsible for everything that happens in your life. Failures think that everything happens by accident and chance. Successful people realize that they are responsible.
Everything happens as a result of something. If we can identify the cause, we can control the effect. We are responsible for what we choose to think and believe. One generally rises to the level that one expects. We are responsible for setting our expectations. Our success is dependent upon our level of confidence.
In short, in all areas of your life, whether they are financial, physical, emotional, or spiritual, you are responsible. Once you recognize this, accept it, and firmly believe it, you are on the road to success.
【小題1】People with low self-esteem are compared to leaves because they ______.

A.a(chǎn)re easily affected by windy weather
B.a(chǎn)re ready to change their minds
C.don’t have the power to face their fate
D.can’t control themselves
【小題2】 Losers would think that ______.
A.their failure is only because of bad luck
B.they don’t make efforts to succeed
C.working hard will lead to success
D.success is the result of hard work
【小題3】It can be inferred from paragraph 5 that ______.
A.success is a chance
B.We are what we make us
C.thoughts and beliefs are the result of creative mind
D.developing confidence is the only way to future success
【小題4】The last paragraph serves as ______.
A.the proof of the author’s points

A person, like a commodity(商品), needs packaging. But going too far is absolutely undesirable. A little exaggeration(夸張) will do no harm when it shows the person’s unique qualities to their advantages. To show personal attractiveness in a casual and natural way, it is important for one to have a clear knowledge of oneself. A skilled packager knows how to add art to nature without any signs of embellishment so that the person so packaged is not a commodity, but a human being, lively and lovely.
A young person, especially a female, shining with beauty and full of life, has all the favor granted. Youth however, comes and goes in a flash. Packaging for the middle-aged is primarily to hide the marks made by years. If you still enjoy life enough to keep self-confidence and work at pioneering work, you are unique in your natural qualities, and your attractiveness and grace will remain. Elderly people are beautiful if their river of life has been, through plains, mountains and jungles, running its course as it should. You have really lived your life, which now arrives at a self - satisfied stage of quietness and calmness with no interest in fame or wealth. There is no need to make use of hair dyeing. The snow-capped mountain itself is a beautiful scene of fairyland. Let your looks change from young to old in step with the natural ageing process so as to keep in harmony with nature, for harmony itself is beauty, while the other way round will only end in unpleasantness. To be in the company of the elderly is like reading a thick book of good edition, which attracts one so much that one is unwilling to part with it. As long as one finds where one stands, one knows how to package oneself, just as a commodity sets up its brand by the right packaging.
【小題1】The underlined word in the first paragraph is closest to the word ______ in meaning.

A.decoration B.clarification C.movement D.identification
【小題2】It can be concluded from the text that ______.
A.people should be packaged at all ages
B.people should be packaged in a special way
C.elderly people also care about packaging
D.proper packaging makes people attractive
【小題3】For the middle-aged, attractiveness ______ .
A.hardly exists B.is the strongest
C.comes from the inside D.comes from the appearance
【小題4】According to the author, if you want to keep in harmony with nature, you should ______.[源
A.dye your hair B.make up at a young age
C.follow the ageing process D.give up fame and wealth
【小題5】The underlined sentence means that elderly people ______.
A.a(chǎn)re usually packaged like a finely-made book
B.experience a lot and have rich knowledge of life
C.do a lot of traveling and can give you much information
D.enjoy reading thick books about beautiful nature and fairyland
