Renting a color television makes more sense than buying. Here‘s why:
1. The longer you rent (租), the less you pay. Each year the monthly rate is reduced. You can reach a low rate of not much more than $12 a week.
2. Service is fast and free. We can have your set installed (安装) in two days. If anything goes wrong, we‘ll have it fixed the same day or lend you another set while we‘re mending it. And don‘t forget: service and spare parts are free!
3. If you don‘t have an aerial (天线), we‘ll install one for you, and that will be free, too. All you have to pay is the installation charge (安装费)!
4. You can choose from all kinds of models, and what‘s more, if after a certain period of time, and you would like a new model, you can change. How‘s that for service?
5. No deposit (押金) is needed. You pay only the monthly rental fee. But if you pay in advance, you can save money. Pay twelve months‘ fees when you begin to hire, and we‘ll give you a month‘s hire without charge.
6. If you decide that you want to stop renting and buy the set you have on hire, this can be arranged—with a generous allowance (折扣) for the fees already paid. 1. From the passage we know _______________________. A. the more you rent, the less you pay

We have known for a long time that flowers of different plants open and close at different time of day. This is so familiar that there seems to be no need to ask the reason for it. Yet no one really understands why flowers open and close like this at particular times. The process (过程) is not as simple as we might think, as recent experiments have shown. In one study, flowers were kept in constant (连续的) darkness. We might expect that the flowers, without any information about the time of day, did not open as they normally do. In fact, they continued to open at their usual time. This suggests that they have some mysterious (神秘的) way of knowing the time. Their sense of time does not depend on information from the outside world; it is, so to speak, inside them, a kind of ―inner clock‖.
This discovery (发现) may not seem to be very important. However, it was later found that not just plants but also animals —including man —have this ―inner clock‖ which controls the working of their bodies and influences (影响) their activities. Men, then, are also influenced by this mysterious power. Whether we wish it or not, it affects such things in our life as our need for sleep, our need for food.
In the past, this did not matter very much because people lived in natural condition. In the modern world, things are different; now there are spacemen, airplane pilots and, in ordinary life, a lot of people who have to work at night. It would be very useful, then, to know more about the ―inner clock‖. Such ordinary things as flowers might help us understand more about ourselves.
1. A recent experiment showed that ________________. A. different flowers open and close at different times of day
B. for their opening and closing, flowers do not need information from the outside world C. flowers are influenced by weak light even when they are in a dark room D. flowers can be used for telling the time 2. The ―inner clock‖ _________________________.
A. is an unimportant discovery B. is only found in animals C. has not been understood by far D. has an effect on human life
