In a book called Magnificent Obsession,by Lloyd C.Douglas,a description is given of people helping others but doing it secretly.When difficult problems worried an individual,friends nearby would meet to discuss possible solution without the individual knowing their actions.When a solution was agreed upon,one or two of the friends would carry out the plan and solve the problems secretly,to the great delight of the worried individual.The helpers would stand by privately,contented with their success.No reward was given to the problem solvers,not even a sincere “thank you”,because they were never known.

This concept is popular today but in a different way.The phrase “pay_it_forward” is now used when one person helps another.However,the person being helped may not be able to repay the person or group that helped them.So rather than return the favor to their helpers,they are supposed to help someone else in the future,which means they pay it forward.It is the sense of responsibility that makes us want to give back in equal measure to the one who has helped us.But,in this case,the responsibility turns to helping someone in the future.

Suppose your elderly grandmother pays part of your schooling.She may tell you there is no need to repay her because it is a gift from someone who loves you very much.Nothing would please her more than to have you use her money to get a good education.

You may never be able to repay her for such a gift.However,she not only gave you some money,but she provided you with an example that you should also help other people who need it.

People with serious needs are everywhere.Many are children who need better clothes,more books and even better schools.Some are elderly people who can’t afford their medicine or a doctor’s care.Consider how you can “pay it forward”rather than pay money back to your grandmother.

Woman Uses Daughter's Key to "Steal" Car

Charlie Vansant, a college student of Athens, Ohio, who reported that his car was stolen, got a surprise when he learned a woman had mistaken it for her daughter's car and taken it — using her key.

Kate Anderson became an accidental car thief when picking up her daughter's car near an Ohio University building last week. Anderson spotted the Toyota Camry(丰田凯美瑞)and used her daughter's key to unlock the car, start the engine and drive home — without realizing that the car wasn't her daughter's.

When Charlie Vansant left class a short time later, he found only an empty parking spot. He first assumed the car had been towed, but when the police couldn't find a record of it, they took a theft report.

The morning after Anderson took the car, her daughter discovered the Camry in the driveway wasn't hers. Anderson said she was able to find Vansant's name on paperwork in the glove compartment and look up his phone number on the website for the university.

When Anderson told Charlie the car was in her driveway, "It sounded really suspicious at first, as she wanted to hold the thing for ransom (赎金) , ” said Vansant. He eventually went to the house with a police officer, where he was reunited with his car. According to the police report, the case was closed "because of mistaken car identity", and Anderson wasn't charged.

Vansant seemed to blame the car company more than the "thief". "Her key fitted not only my lock, but my ignition(点火装置)as well — so high-five for Toyota, I guess." he said.

1. What does the underlined word "towed" mean in paragraph 3?

A. sold B. damaged.

C. stolen. D. removed

2.Which of the following is NOT true according to the passage?

D. Mrs. Anderson used her daughter's key to unlock Charlie's car and drive home.

3. What does Charlie mean by "high-five for Toyota"?

A. He should thank Toyota for returning his car.

B. He is blaming Toyota for the poor quality of car keys.

C. He wants to celebrate with Toyota for getting his car back.

D. He thinks highly of Toyota for producing large quantities of cars.

4.What is likely to happen next according to the passage?

A. Mrs. Anderson was charged with stealing a car.

B. Charlie blamed Mrs. Anderson for mistakenly taking his car.

C. Charlie would ask the Toyota Company to give him an explanation.

D. The Toyota Company would give Charlie a new car as compensation.

Parents and the Young

It is natural that young people are often uncomfortable when they are with their parents.

1. They often think that their parents are out of touch with modern ways, that they are too serious and too strict with their children, and that they seldom give their children a free hand.

It is time that parents often find it difficult to win their children’s trust and they always forget how they themselves felt when young. 2. It is one of their ways to show that they have grown up and they can face any difficult situation. Adults worry more easily. Most of them plan things ahead.

Young people make their parents angry with their choices in clothes, in entertainment and in music. But they do not mean to cause any trouble: It just shows that they feel cut off from the adult’s world, and they have not yet been accepted into their world. 3. And if their parents do not like their music or entertainment or clothes or their way of speech, this will make the young people very happy.

Sometimes you are so proud of yourself that you do not want your parents to say “yes” to what you do. 4. It is natural enough, after being a child for so many years, when you were completely under your parents’ control.

5. If your parents see that you have a high sense of responsibility, they will give you the right to do what you want to do.

A. Parents should understand young people.

B. Young people like to live with their parents.

C. Young people like to act without much thinking.

D. They say that their parents don’t understand them.

E. All you want is to be left alone and do what you like.

F. If you plan to control your life, you’d better win your parents.

G. That’s why young people want to make a new culture of their own.

Sharks have lived in the oceans for over 450 million years. There are now about 360 species of sharks, whose size, behavior, and other characteristics differ widely.

Sharks range in size from the 0.1 meter long dwarf-dog shark to the 18-metre long whale shark — the world’s biggest fish. The whale shark, like two other large shark species — the basking shark and the megamouth shark — are harmless to people because they feed on plants and small aquatic animals.

Sharks have extremely sensitive sense organs. Some sharks can detect the scent(气味) of decaying fish or blood even when it is diluted(稀释) to only one part per million parts of seawater. They can probably hear underwater sounds that originate as far as 3 kilometers away and can tell the direction from which underwater sounds are coming.

Sharks are key predators(肉食动物) in the world’s oceans, helping control the numbers of many other ocean predators. Without sharks, the oceans would be overcrowded with dead and dying fish.

Every year, we catch and kill over 100 million sharks, mostly for food and for their fins. Dried shark fins are used to make shark fin soup, which makes a profit for the sellers. Other sharks are killed for sport and out of fear. Sharks are vulnerable to overfishing because it takes most species 10 to 15 years to begin reproducing and they produce only a few offspring.

Influenced by movies and popular novels, most people see sharks as people-eating monsters. This is far from the truth. Every year, a few types of sharks injure about 100 people worldwide and kill about 25. Most attacks are by great white sharks, which often feed on sea lions and other marine mammals. They sometimes mistake human swimmers for their normal prey, especially if they are wearing black wet suits.

If you are a typical ocean-goer, your chances of being killed by an unprovoked(无缘无故的) attack by a shark are about 1 in 100 million. You are more likely to be killed by a pig than by a shark.

Sharks help save human lives. In addition to providing people with food, they are helping us learn how to fight cancer, bacteria and viruses. Sharks are very healthy and have aging processes similar to ours. Their highly effective immune system allows wounds to heal quickly without becoming infected, and their blood is being studied in connection with AIDS research.

Sharks are among the few animals in the world that almost never get cancer and eye cataracts. Understanding why can help us improve human health. Chemicals extracted from shark cartilage(软骨) have killed cancerous tumors in laboratory animals, and these chemicals may someday help prolong our life.

Sharks are needed in the world’s ocean ecosystems. Although they don’t need us, we need them. We are much more dangerous to sharks than they are to us. For every shark that bites a person, we kill one million sharks.

1.Which statement best expresses the main idea of the article?

A. There are many different species of sharks, but only a few of them are dangerous to humans.

B. Sharks are important to the ocean ecosystem and they are a valuable resource for humans.

C. Although some sharks are dangerous to humans, they can help save human lives.

D. Sharks always eat small fishes and they are an essential part of the world’s oceans.

2.Which question is NOT answered in the article?

A. How long does a shark live?

B. How many people are killed by sharks each year?

C. Why are sharks important in medical research?

D. What do humans kill sharks for?

3.It can be inferred from the passage that ______________.
