When you feel sad, tears will roll down your cheeks. When you are happy, especially when you laugh very hard, tears also will roll down your face. But tears have a more important job than showing how you feel.
Tears keep your eyes clean and healthy. They washed away dirt and germs(细菌) and other things that get in your eyes. Your eyes also need tears to keep them wet. Your eyes must be wet so that they can move smoothly. Your eyes are busy looking here and there all day long. They move quickly from one thing to another. If you didn't have tears, your eyes couldn't move, and soon you would be blind.
But where do these tears come from?
Under each eyelid(眼睑) are tiny sacs called tear glands. That's where tears are made. Every time you blink your eyes, some tears are pushed out of these glands. The tears wash over your eyes and soothe(滋润) them.
When you're not laughing or crying your tears away, where do they go? They go away through small holes in your lower eyelid. Some of there holes lead into your nose. Many times when you cry, the tears drip down through your nose-and it starts to run. The drops that fall from your nose are your tears.
Maybe you don't like baths, but your eyes can't do without them.

1.A(主旨大意题.这篇短文的主题就是告诉我们怎样以及为什么人会流眼泪.) 2.C(综合概括题.综合短文第二段中Tears keep your eyes clean and healthy.They wash away dirt and germs and other things that get in your eyes.的内容,我们不难判断出眼泪的主要功能就是把眼泪里的脏东西洗掉.) 3.B(生活常识题.人们不是哭或高兴而眼中有泪的话,一定是空气中有灰尘或者是风太大.) 4.A(该题考查事实细节.由短文第二段中Your eyes must be wet so that they can move smoothly.可知,没有眼泪的滋润,眼球就不会转动那么灵活.) 5.B(细节题.短文倒数第二段中Every time you blink your eyes,some tears are pushed out of these glands.说明,不停地眨眼就会出眼泪.) |
