China is going green. In order to reduce air pollution and oil shortages, 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.

1.The author writes this passage mainly to________.

A. teach people how to drive a hybrid car

B. show how to save their gasoline when driving a car

C. introduce a new kind of "green" car

D. announce plans to develop hybrid vehicles for China

2.The first sentence probably refers to ________.

A. there will be more and more green land in China

B. China has started producing environmentally friendly cars

C. China's new cars are combinations of different green models

D. China is still young and lacking experience

3.What is the most important feature of hybrid cars?

A. They have smaller engines than traditional gasoline ones.

B. They are much quieter than traditional cars.

C. They only use 99 percent of their power to run up hills.

D. They are powered by both a rechargeable battery and gasoline.

The drug store was closing for the night. Young Alfred Higgins, the shop-assistant, was ready to go home. Mr. Carr, the boss, stared at him and said: “Hold on, Alfred. Maybe you'd be good enough to take the things out of your pockets and leave them here before you go.” Alfred's face got red. After a little hesitation, he took out what he had stolen. Mr. Carr said, “Maybe I should call your mother and let her know I'm going to have to put you in prison.”

Alfred thought his mother would come rushing in, eyes burning with anger. But, to his surprise, she arrived wearing a smile. “Hello, I'm Alfred's mother. Is he in trouble?” she said. Mr. Carr was surprised, too. He had expected Alfred's mother to come in nervously, shaking with fear, asking with wet eyes for a mercy for her son. But no, she was most calm, quiet and pleasant and was making Mr. Carr feel guilty…. Soon Mr. Carr was shaking his head in agreement with what she was saying. “Of course”, he said, “I don't want to be cruel. You are right. Sometimes, a little good advice is the best thing for a boy at certain times in his life and it often takes the youths long time to get sense into their heads.” And he warmly shook Mrs. Higgins's hand.

Back home, without even looking at Alfred, she said, “You are a bad luck. It is one thing after another, always has been. Why do you stand there so stupidly? Go to bed.” In his bedroom, Alfred heard his mother in the kitchen. There was no shame in him, just pride in his mother's strength. He felt he must tell her how great she was. As he got to the kitchen, he saw his mother drinking a cup of tea. He was shocked by what he saw. His mother's face was a frightened, broken one. It was not the same cool, bright face he saw earlier in the drug store. As she lifted the tea cup, her hand shook. And some of the tea splashed on the table. Her lips moved nervously. She looked very old. He watched his mother without making a sound. The picture of his mother made him want to cry. He felt his youth coming to an end. He saw all the troubles he brought his mother in her shaking hand and the deep lines of worry in her grey face. It seemed to him for the first time he had ever really seen his mother.

1.Which of the following is probably said by Mrs. Higgins while talking to Mr. Carr?

A. “Please, for God's sake, you know, he is just a kid.”

B. “I can't believe it! You are treating my son like that!”

C. “Punishment makes sense because it teaches about the law.”

D. “You know, it takes time for a youth to truly grow up.”

2.What does the underlined phrase "his mother's strength"(Para. 3) refer to?

A. Mrs. Higgins's attitude towards parental sufferings.

B. Mrs. Higgins's calmness and communicating skills.

C. Mrs. Higgins's love and care for her son Alfred.

D. Mrs. Higgins's greatness as a woman.

3.After the incident, young Alfred would probably ________.

A. change his attitudes towards life

B. feel ashamed of her mother

C. learn to live an independent life

D. hate Mr. Carr for hurting her mother

根據(jù)短文內(nèi)容，從短文后的選項中選出能填入空白處的最佳選項。選項中有兩項為多余選項。

Although many Chinese students say that their knowledge of English grammar is good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student, they always say, “My spoken English is poor.” 1. I would like to suggest that there may be some reasons for their problems with spoken English.

First, they fail to find suitable words to express themselves due to a limited vocabulary. 2. However, you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow you as long as you use the words that you know.

_3. Sometimes they make mistakes when they are speaking because they are shy and nervous. Yet students should remember that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate following the rules for grammar and using them to get your message across. But to talk to someone in English, as quickly and well as you can, even though sometimes you may use a wrong word or tense, but it doesn’t matter. 4.

The third reason is that not enough attention is paid to listening. You have one mouth but two ears! All the hearing is necessary for you to start speaking.

Fourth, most Chinese students are reactive rather than proactive(主動的) language learners. Instead of actively seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them and wonder why their English always remains poor. 5.

A. Second, they are afraid of making mistakes.

B. They may try to avoid making similar mistakes next time.

C. Obviously the better answer is to expand their vocabulary.

D. However, their spoken English does not have to remain “poor”!

E. The second reason lies in the reluctance (不愿) of using what has just been learned.

F. The person you are speaking to will understand you and make allowances for any mistakes he hears.

G. If you have this proactive outlook, then you will see English opportunities wherever you go.

That cold January night, I was growing sick of my life in San Francisco. There I was, walking home at one in the morning after a tiring practice at the theatre. With opening night only a week away, I was still learning my lines(臺詞). I was having trouble dealing with my part-time job at the bank and my acting at night at the same time. As I walked, I thought seriously about giving up both acting and San Francisco. City life had become too much for me.

As I walked down empty streets under tall buildings, I felt very small and cold. I began running, both to keep warm and to keep away from any possible robbers (搶劫犯). Very few people were still out except a few sad-looking homeless people under blankets.

About a block from my apartment, I heard a sound behind me. I turned quickly, half expecting to see someone with a knife or a gun. The street was empty. All I saw was a shining streetlight. Still, the noise had made me nervous, so I started to run faster. Not until I reached my apartment building and unlocked the door did I realize what the noise had been. It had been my wallet falling to the sidewalk.

Suddenly I wasn’t cold or tired anymore. I ran out of the door and back to where I’d heard the noise. Although I searched the sidewalk anxiously for fifteen minutes, my wallet was nowhere to be found.

Just as I was about to give up the search, I heard the garbage truck (垃圾車) pull up to the sidewalk next to me. When a voice called from the inside, “ Alisa Camacho ?” I thought I was dreaming. How could this man know my name? The door opened, and out jumped a small red-haired man with an amused look in his eye. “Is this what you’re looking for?” he asked, holding up a small square shape.

It was nearly 3 A.M. by the time I got into bed. I wouldn’t get much sleep that night, but I had gotten my wallet back. I also had gotten back some enjoyment of city life. I realized that the city couldn’t be a bad place as long as people were willing to help each other.
