The art of reading fiction is largely a matter of inferring meanings. To infer means to understand facts which are not directly stated---only suggested. Inference is one of the commonest ways of knowing things: a child holds his knee and cries; this action implies his feeling; an observer infers that the child is hurt. To infer accurately in everyday life requires caution in observing; to infer skillfully in fiction requires caution in reading; both require disciplined imagination.
The short-story reader can expect to find certain basic elements in any story. For example, all stories involve a person or persons, in a particular setting, faced with a demand for a response. The response called for may be a physical action, such as defeating an adversary(對手) or escaping from a danger; or it may be a mental action, such as adjusting to others or within oneself. In either case, the short story is a description in two ways: first, it shows the motives for a given human action; second, it makes a point about the general human situation. Such descriptions, however, rather than being stated directly, usually are implied by the elements of the story.
When the reader of a story understands all the facts and their interrelationships, he is ready to infer the significance of the story as a whole---its comment on the human situation. This comment, or theme, is the seed from which the story grew. It is also the idea by which all the separate elements of the story are governed, while these in turn further shape and modify the theme. In addition to action, character, and setting, these elements include structure, mood, tone, and point of view.
Fiction reading requires an awareness of all the ways in which a story communicates. It also requires attention to detail. What the author provides is a network of points which serve as clues to his meaning. He invites the reader to develop the meaning by inference, actually to create much of the story himself and so make it part of his own experience.
小題1:According to the author, "infer" means ________ .
A．knowingfactsbeyondthestatement
B．lookingformoreevidencesforthestatement
C．findingoutadifferentmeaningfromthestatement
D．a(chǎn)ddingsomefactstothestatement
小題2:What is inferring in fiction based on?
A．Readers’guessing. B．Thebasicelementsofthestory.
C．Thesettingofthestory. D．Theinterrelationshipsbetweenpeopleinthestory.
小題3:What is the implied meaning of the last sentence?

There is no question that teenagers need rules, which is often not a difficult thing for parents to give. What can be more challenging is giving teenagers their freedom. It can be difficult to draw the line between the two. However, some issues cannot be changed by discussion and require firm rules. For instance, rules should be established concerning driving the family car.
I will admit that I have no problem coming up with rules. To me they make life easier and they leave no room for questioning. What can be more difficult, however, is giving my teens their freedom. I guess there are really two primary reasons for this. One is that I sometimes am afraid to give them freedom. The second is that I’m not always so sure what the freedom should be.
It helps that I have a husband with whom I can discuss these problems. We talk about them, give our thoughts and then we come up with an agreement. Sometimes one of us might be more unwilling but we know that there comes a time when we really do have to learn how to let go of the reins (韁繩) a bit.
If we try to make life have nothing but rules, we are more likely to see our teen’s rebelling (反抗). They need to know that while we do have certain expectations, we also trust them to begin making their own choices and decisions. How else can they do that unless they are given the space and room to do it?
It’s really all about balance and I will be the first to admit that it can be a challenge to carry out. However, it is a necessary part of growing up. Yes, teens definitely need rules but they also need freedom.
小題1:According to the text, we can infer that the writer________.
A．refuses to give her children freedom
B．finds it difficult to make rules
C．doesn’t have a good relationship with her children
D．has trouble in giving freedom to her children
小題2:According to the writer, only rules without freedom will make the children _______.
A．strong-willedB．rebelliousC．weakD．independent
小題3:Which of the following is TRUE according to the text?
A．Rules are difficult to make for parents.
B．Rules and freedom are similarly important.
C．We should give children freedom as much as possible.
D．Rules are more important than freedom.
小題4:What does the underlined word “them” in Paragraph 3 probably refer to?
A．Problems.B．Children.C．Rules. D．Reasons.

Over the past decade, cheating—an act of academic dishonesty—has become more and more common.
The latest statistics shows more than two thirds of high school students admitted cheating on an exam last year, and—even more surprising—often the best students cheat to get to the top of their class—and they don’t think it is wrong. It’s not a big deal. Everybody is doing it.
It is a big deal! Cheating is basically wrong and must be punished.
If students easily get away with it, they might be encouraged to do it again. They won’t realize that this—in the broadest sense—is an attack on our society, which is based on values like honesty and fairness. The present spreading of cheating indicates a loss of those values and cannot be tolerated. An appropriate punishment for cheating incidents would make students aware of their misbehavior.
If no one were punished for cheating, who would ever study for an exam? Tons of papers would be lifted from websites, writing crib sheets would be more important than reviewing the subjects, and highly sophisticated cheating arts would be invented. Knowledge would only exist on the Internet and on cleverly created cheat sheets, but not in the minds of the students—a rather bad precondition to enrich our society wisely and intelligently.
Students have to learn that they have to learn. Only doing what’s right will bring them a feeling of pride and accomplishment and create self-confidence—the building blocks for a successful and satisfying life and a society that keeps its values.
小題1:What is more surprising is that       .
A．cheating is very common in schools
B．over 2/3 of the students cheat last year
C．even the best students cheat on exams
D．teachers are not aware of the problems
小題2:How do they make the students realize their misbehavior?
A．By letting them getting away with it.
B．By telling them what is right.
C．By catching them on the spot.
D．By giving them some punishment.
小題3:How can students create self-confidence?
A．By knowing they have to learn.
B．By doing what is right.
C．By learning the right things.
D．By being punished when cheating.
小題4:What does the underlined word “l(fā)ifted” mean?
A．takenB．removedC．copiedD．written

Education is not an end , but a means to an end. In other words, we do not educate children only for the purpose of educating them. Our purpose is to fit them for life.
In many modern countries it has for some time been fashionable（流行的）to think that by free education for all whether rich or poor, clever or stupid --- one can solve all the problems of society and build a perfect nation. But we can already see that free education for all is not enough: we find in such countries a far larger number of people with university degrees（學(xué)位）they refuse to do what they think "low" work; and in fact, work with hands is thought to be dirty and shameful in such countries. But we have only to think a moment to understand that the work of a completely uneducated farmer is far more important than that of a professor: we can live without education, but we die if we have no food. If no one cleaned our streets and took the rubbish away from our houses, we should get terrible diseases in our towns…
In fact, when we say that all of us must be educated to fit us for life, it means that we must be educated in such a way that, firstly, each of us can do whatever work suited to his brains and ability, and secondly, that we can realize that all jobs are necessary to society, and that it is very bad to be unwilling to do one's work. Only such a type of education can be considered valuable to society.
小題1:In the writer’s opinion,_________
A．free education for all probably leads to a perfect world
B．a(chǎn)ll the social problems can’t be solved by education
C．education can solve most of the world’s problems
D．free education will help to solve all the problems of society
小題2:The writer wants to prove that _______
A．a(chǎn) farmer is more important than a professor
B．our society needs free education for all
C．our society needs all kinds of jobs
D．work with hands is the most important
小題3:The purpose of education is to ________
A．build a perfect worldB．let everyone receive education
C．choose officials for the countryD．prepare children mainly for their future work
小題4:What is mainly discussed in the text?
A．The type of educationB．The value of education
C．The means of educationD．The system of education
小題5:What can we learn from the text?
A．Work with hands is thought to be shameful in some modern countries.
B．In all modern countries, free education has been fashionable.
C．A perfect nation can solve all the problems of society.
D．A professor is far more important than a farmer.

China_is_going_green. In order to reduce air pollution and oil­shortages, automobile manufacturers have announced their plans to develop hybrid vehicles (混合燃料汽車) for the Chinese market. Toyota's hybrid car Prius will be ready to drive in China this week. Let's have a look at the new car.
Any vehicle is a hybrid when it combines two or more sources of power. Hybrid cars run off a rechargeable battery and gasoline. Hybrid cars have special engines, which are smaller than traditional gasoline engines. They run at 99 percent of their power when the car is cruising (勻速行駛). A specially designed battery motor provides extra power for running up hills or when extra acceleration is needed.
Step into a Prius, and turn on the engine. The first thing you notice is how much quieter it is than a traditional car. At this point, the car's gasoline engine is dormant (休眠). The electric motor will provide power until the car reaches about 24 km/h. If you stay at a low speed, you are effectively driving an electric car, with no gasoline being used, and no waste gas gives off.
The onboard(車載的) computer makes the decision about when to use a gas engine, when to go electric, and when to use a combination of the two. If you go over 24 km/h, when you step on the gas pedal (油門), you are actually telling the computer how fast you want to go.
The electronic motor recharges automatically using a set of batteries. When driving at high speed, the gasoline engine not only powers the car, but also charges the batteries. Any time you use the brake, the electric motor in the wheels will work like a generator and produce electricity to recharge the batteries. As a consequence, the car's batteries will last for around 200,000 miles.
小題1:The author writes this passage mainly to________.
A．teach people how to drive a hybrid car
B．introduce a new kind of “green” car
C．show how to save their gasoline when driving a car
D．a(chǎn)nnounce plans to develop hybrid vehicles for China
小題2:The first sentence probably refers to ________.
A．there will be more and more green land in China
B．China is still young and lacking experience
