We all know that a good night's rest helps us stay healthy. After we sleep for 7 or 8 hours in bed and {#blank#}1{#/blank#} up next morning, our mind is better prepared to memorize and learn something.

    But what about getting a rest during the middle of the day?

    Scientists say, “Short periods of sleep, napping (小睡), may help learning and memory. Napping can help young children learn better. It can {#blank#}2{#/blank#}  help older people remember longer.”

    Take China as an example. Chinese people are used to napping after lunch.

    Recently researchers made a survey among nearly 3,000 Chinese people over 65 years old. The researchers asked them {#blank#}3{#/blank#} they napped and for how long. They found that about 60 percent of them took a nap and they napped for 60 to 90 minutes. The research shows that napping for about an hour is the best.

    However, these are the findings for those  {#blank#}4{#/blank#} the age of 65. Doctors say that napping for about an hour may be too  {#blank#}5{#/blank#} for young and healthy people. And they believe that half an hour is enough to {#blank#}6{#/blank#} young and healthy people from feeling tired. By doing so, {#blank#}7{#/blank#} will help them stay awake.

    Doctors also say, “If you have trouble falling asleep at {#blank#}8{#/blank#} , take a daytime nap for less than 45 minutes and don't nap after 3 p.m. in the afternoon.

    In the new century, people invented some "smart clothes". They {#blank#}1{#/blank#} (use) not only for covering your body, but also for many kinds of uses. Some kinds of smart clothes have come into the market. A German clothing maker has invented the"MP3 blue jacket". This kind of jacket has two functions. It is both an MP3 player {#blank#}2{#/blank#} a mobile phone. Besides, {#blank#}3{#/blank#} English company has developed a cloth keyboard that can be put onto your pants. You can control your computer with it {#blank#}4{#/blank#} (easy) anywhere. The keyboard can be washed {#blank#}5{#/blank#} it gets dirty. And it can be even ironed.

    As the technology improves, smart clothes will become much {#blank#}6{#/blank#} (smart). Researchers are developing clothes {#blank#}7{#/blank#} can show your body temperature and heat you up before you feel cold. Other smart clothes to wear are special medical ones. They can tell the doctor when you are {#blank#}8{#/blank#} danger. This technology can also provide important information about your environment. Shirts can warn you of high pollution levels. Jackets with GPS technology can keep you from {#blank#}9{#/blank#} (get) lost.

    People have begun {#blank#}10{#/blank#} (love) the idea. Probably, smart clothes will be common on Paris streets, and even in your own home one day.

    Now more and more Chinese teenagers find life more difficult without their parents. They don't know how {#blank#}1{#/blank#}(do) housework {#blank#}2{#/blank#} their parents almost do everything at home. That is a big problem.

    Joy is a fourteen-year-old girl. One day, her parents went away on a trip, so she was alone at home. At first she {#blank#}3{#/blank#}(think) she would be happy because her parents were not in. She could do what she liked. But when it was six o'clock in the afternoon, she felt {#blank#}4{#/blank#}(hunger)."Oh, it's time {#blank#}5{#/blank#}(have) dinner. Where can I get my dinner?" she said to {#blank#}6{#/blank#}(she). Later she found some meat and vegetables in the fridge, {#blank#}7{#/blank#} she didn't know how to cook them. At that moment, she missed her parents very much. At last she could only go to the supermarket to buy some food to eat.

    Many teenagers have {#blank#}8{#/blank#} same problem. So I think they should learn some life skills, like {#blank#}9{#/blank#}(cook), tidying up their rooms or dressing themselves. They shouldn't depend {#blank#}10{#/blank#} their parents too much.

    Doing homework not only can help children master the knowledge they have learnt but also can train their abilities of finishing the work alone, {#blank#}1{#/blank#} (plan) the time and doing the {#blank#}2{#/blank#} (duty). But some children don't like to complete the work .Why? There are some reasons.

    Some children feel it is very difficult {#blank#}3{#/blank#} (do) their homework, because they can't understand their teacher {#blank#}4{#/blank#} (clear), and can't follow their teacher's teaching process. Maybe there is something wrong with their intelligence.

    But some children's intelligence is normal. They are even {#blank#}5{#/blank#} (clever), but they don't listen to the teacher {#blank#}6{#/blank#} (careful). It is hard for them {#blank#}7{#/blank#} (sit) well and pay attention to anything. It needs to carry on the attention centralized (集中注意力) training {#blank#}8{#/blank#} (help) the children.

    Some children love their teacher and then they like the subject. Their interest depends on the teacher who {#blank#}9{#/blank#} (teach) them. So every teacher should be {#blank#}10{#/blank#} (help) and kind. It can make children love you and the subject you teach. So they can do their homework happily.
