补全短文。根据短文内容，从短文后的A-F选项中选出适当的选项补全短文。（共5 小题，计5分）
【小题1】Is this true? Maybe it is, or we won't be healthy and clever.
【小题2】Children of our age need nine hours sleep every day. If we don't go to bed early, we won't have enough sleep. Then we can't think properly and can't do our work properly. We will not be clever.
【小题3】This is not good for them. We must go to bed at night when it is dark. The dark helps us to sleep. When the daytime comes, we must get up. This is the time for exercise.
【小题4】Exercise keeps a strong body.
【小题5】This is very important. Blood takes food to all parts of our body. The brain also needs blood. We think with our blood. We can think better if we keep our body healthy and take exercise.
A. The body must have enough sleep．
B. Exercise helps the blood (血液) go around inside the body.
C. But it’s necessary to take some exercise every day.
D. Everyone must go to bed early and get up early.
E. If we lack (缺少) exercise, we will become weak.
F. Some people go to bed late and get up late.
D

(答案→)D 解析：短文大意：每一个人都必须早睡早起。身体必须有足够的睡眠，锻炼有助于血液的循环。如果我们不早点上床睡觉，我们就不会有足够的睡眠。我们就不能正确地思考，也不能正常工作。我们将不聪明。【小题1】根据后文叙述可知选D，每一个人都必须早睡早起。【小题2】根据We will not be clever.和If we don't go to bed early, we won't have enough sleep.可知选A，身体必须有足够的睡眠。【小题3】根据This is not good for them. We must go to bed at night when it is dark 可知选F，有的人晚睡晚起。【小题4】根据Exercise keeps a strong body 可知选 E，如果我们缺乏运动，我们就会变得虚弱。【小题5】根据Blood takes food to all parts of our body和We can think better if we keep our body healthy and take exercise.可知选B，锻炼有助于血液的循环。
