I finished my last work of the week and could hardly wait to get home, take off my nursing shoes, and relax.

　 As I approached(走近) my 　36 , I saw one of my 　37 standing by the bus stop. I thought it would only take a couple of extra minutes to give her a ride home, and besides, it was 　38 cold to be standing outside on the coldest 　39 in January. I didn’t know where she lived, but I was 40 I would be able to find my way back.

　 We 　41 about our work as I drove and before we knew it, we arrived at 　42 house. I started driving back. 　43 looked familiar, but at first that didn’t bother me. But soon I 　44 something wrong. I 　45 nothing. But I told myself to stay 　46 .

　 I was beyond neighborhoods, streets and 　47 streetlights. I no longer knew where I was now. How could I be so stupid! I looked down at my 　48 . It was now 2:30 a.m. My gas was slowly running out. I 　49 the car and turned off the engine. In total defeat, I put my head down on the wheel, 　50 . Then I raised my head and 51 a shadow down the road in front of me. I turned my headlights on. A car! I drove a little 52 .got out of my car and knocked on the window of that car. An elderly man 　53 rolled his window down.

　 I said that I didn’t know how to get back into town. In silence, he started driving. I ran back to my car and drove 　54 him. Finally I recognized a(n) 　55 street. As I turned to head home, the car disappeared. Then I pulled into my driveway (车道) when the warning light for my gas tank (汽油箱) turned on.

　 Though so many years have passed, I still thank the old man from my deepest heart.

　　China is going green. In order to reduce air pollution and oil-shortages, automobile manufacturers have announced their plans to develop hybrid vehicles（混合燃料汽车）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 on 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（巡航）. 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（车载的）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（油门）, 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.

    The petrol tank is fitted at the back of the car where it is out of the way, yet easily filled at a gas station. Tanks are in various capacity (溶量) but they usually hold enough petrol for 250-300 miles running. Because the tank is at the opposite end of the car from the carburetor, which is fitted high up on the engine, a pump is needed to draw the petrol from one to the other, as it is from the carburetor that the petrol in finally fed into the engine. Pumps can be of two kinds: electrically operated or mechanically driven from the engine.

    1. The text tells the reason why ________.

    A. there are different types of tanks in capacity

    B. the tank is designed at the back of the car

    C. the pump in mechanically driven from the engine

    D. the petrol is fed into the engine the carburetor

    2. It is necessary to use a pump to send petrol to carburetor because ________.

    A. the engine needs supply with a certain amount of petrol

    B. the pump can press the petrol to recycle

    C. the carburetor has difficulty in drawing petrol from the tank

    D. the tank isn’t fitted in proper position

    3. According to the text one tube (管道) of the ________ may be joined to the ________ directly.

    A. pump, engine　　　　　　　　　　　　　　　　 B. carburetor, engine

C. tank, carburetor　　　　　　　　　　　　　　 D. engine, tank

In cars of normal design, the petrol (汽油) system is made up of three parts: storage tanks (储油箱), a pump and a carburetor (汽化器).

    The petrol tank is fitted at the back of the car where it is out of the way, yet easily filled at a gas station. Tanks are in various capacity (溶量) but they usually hold enough petrol for 250-300 miles running. Because the tank is at the opposite end of the car from the carburetor, which is fitted high up on the engine, a pump is needed to draw the petrol from one to the other, as it is from the carburetor that the petrol in finally fed into the engine. Pumps can be of two kinds: electrically operated or mechanically driven from the engine.
