完形填空 先通读下面的短文，掌握其大意，然后在每小题所给的四个选项中，选出可以填入空白处的最佳选项。（本大题共10小题，每小题1分，共10分）
Homesick is a compound （复合的） word made up of “home” and “sick”。 You know
15 each word means on its own, of course. But think about what the words mean when they are 16 together. “Homesick” means “Thinking of home, unhappy away from home.” In other words, it means “sick for home”。
Now think for a minute 17 the word SEASICK. If you change the word “home” in the definition （定义） to the word “sea”， would the definition 18 “seasick” ? Does seasick mean “thinking of sea, unhappy away from sea”？ It means something quite 19 . Seasick means “made sick by the only place where you are on the sea.” It means “sick because of the sea.” When you are homesick, the only place you want to be is at home. When you are seasick, the 20 place you want to be is at sea.
Have you ever 21 a person being heartsick? Heartsick does not mean that something is wrong with a person’s heart. People are heartsick when they are 22 down deep inside as if （好像） their hearts are broken.
And so, when you are carsick, you are “made sick by the movement of a car on the road.” You are sick because of the car, not sick for it.
You can see, then, that 2 3 compound words are what they seem at first glance （一瞥）。 Think about the compound words, such as handshake and 24 . Perhaps you may write definitions for them. It must be helpful to know something like this in your English study.
