三、閱讀測驗:(一)　　Do we have enough sleep?  How many hours should we sleep every day?  When we were babies, we slept for about twenty hours.  After we grow up, we should sleep for at least six or seven hours.  Why is sleeping important for us?  If we have enough sleep, we won’t feel tired and we can do our work or learn better.  We can also be energetic.  We will be healthy and won’t get sick easily.  Sleeping can help us grow and learn well.  If we have good and enough sleep, our skin can keep beautiful.  Even if we get older, we can still look young and pretty.　　Now we are busy studying or working, and it may not be easy for us to fall asleep at night.  How can we do?  To get good sleep, we should turn off the lights before we go to bed.  It shouldn’t be too cold or too hot in our bedrooms.  If we want to take a nap after lunch, fifteen or twenty minutes is enough.  Taking a nap too long makes it difficult for us to fall asleep at night.  We shouldn’t drink coffee before we go to bed.  Doing some exercise can also help us sleep.  We shouldn’t think about other things when we are ready to sleep.  For our health, we all need to sleep well.
