我們再給大家介紹一個由eye 組成的俗語：To keep one's eye on the ball.To
keep one's eye on the ball這個常用語原先是來自球類運動，如網球、高爾夫
球、壘球等。你一定要把眼睛看準了才能打到這些球。下面這個壘球運動員說的
話就能說明問題：

    例句-1： We were playing Chicago there and the crowd was yelling and
booing and waving handkerchiefs to distract us. But I kept my eye on the
ball， swung as hard as I could and hit a home run. That Chicago crowd
sure quieted down as I jogged around the bases. 這位壘球手說：“我們那
時正在芝加哥和當地一個球隊比賽，看球的人群又喊又嚷，還揮動手絹想分散我
們的注意力�？墒牵�我集中精力，使出所有的勁兒來打球，結果打了一個本壘打。

    這下，當我沿著壘跑的時候，芝加哥的觀眾就變得很安靜了。“

    讓我們來舉一個汽車推銷員的例子吧。這個人家里有些事不順心，使他在工
作時很分散精力。于是，他的老板就把他叫到辦公室去對他說：

    例句-2： Tom， your sales record is way down the past six months.
You've only sold 17 cars all this time. You'd better start keeping your
eye on the ball ， or you'll find yourself looking for another job. 這
位老板說：“湯姆，你的銷售量在過去半年里一直很低。你在這段時間里一共才
賣了十七輛汽車。你還是集中注意力地工作，否則，你恐怕得另找工作了。”

    還有一個由eye 這個字組成的、非常有用的習慣用語是eye-opener. Eye-opener
是一個字。

    Eye-opener有兩個意思，一個是表示驚奇，就像下面這個女子所表達的情緒
：

    例句-3： Of course， John and I have had a few problems ， just like
most married couples. But I always felt we had a good ， solid marriage.
So it was a terrible eye-opener when I opened the letter he'd left on
the kitchen table and found out he'd run off with his old college sweetheart.
這個被拋棄的妻子說：“當然，約翰和我是有一些矛盾，就像大多數夫妻一樣。

    但是，我一直認為我們的婚姻是有牢固基礎的。所以，當我打開他留在廚房
桌上的信，知道他和他以前大學里的女朋友出走了的時候，我真是非常驚奇。“

    Eye-opener的另一意思是：開闊了眼界。請聽下面這個例子：

    例句-4： Seeing those color films the astronauts took off the earth
on their flight to the moon was certainly an eye-opener. I never realized
how beautiful and how lonely our planet looks hanging there in space.
這句話的意思是：“看到宇航員在登上月球時拍的那些有關地球的彩色照片真是
開了眼界。我從來也不知道我們的地球在空間是這么美麗、這么孤單。”
