综合自测系列答案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 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 (匀速行驶). 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.

Almost every day we come across situations in which we have to make decisions one way or another. Choice, we are given to believe, is a right. But for a good many people in the world, in rich and poor countries, choice is a luxury, something __41__but hard to get, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, a false idea created by companies and advertisers hoping to sell their products.
The endless choice gives birth to anxiety in people’s lives. Buying something as basic as a coffee pot is not exactly __42__. Easy access to a wide range of everyday goods leads to a sense of powerlessness in many people, __43__in the costomer giving up and walking away, or just buying an unsuitable item that is not really wanted. Recent studies in England have shown that many electrical goods __44__ in almost every family are not __45__ needed. More difficult decision-making is then either avoided or trusted into the hands of the __46__, lifestyle instructors, or advisors.
It is not just the availability of the goods that is the problem, but the speed with which new types of products come on the market. Advances in __47__ and production help quicken the process. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The __48__ example is computers, which are almost out-of-date once they are bought. This indeed makes selection a problem. So gone are the days when one could just walk with ease into a shop and buy one thing: no choice, no __49__.
