我们再给大家介绍一个由eye 组成的俗语：To keep one's eye on the ball.To
keep one's eye on the ball这个常用语原先是来自球类运动，如网球、高尔夫
球、垒球等。你一定要把眼睛看准了才能打到这些球。下面这个垒球运动员说的
话就能说明问题：

    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. 这位垒球手说：“我们那
时正在芝加哥和当地一个球队比赛，看球的人群又喊又嚷，还挥动手绢想分散我
们的注意力。可是，我集中精力，使出所有的劲儿来打球，结果打了一个本垒打。

    这下，当我沿着垒跑的时候，芝加哥的观众就变得很安静了。“

    让我们来举一个汽车推销员的例子吧。这个人家里有些事不顺心，使他在工
作时很分散精力。于是，他的老板就把他叫到办公室去对他说：

    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. 这
位老板说：“汤姆，你的销售量在过去半年里一直很低。你在这段时间里一共才
卖了十七辆汽车。你还是集中注意力地工作，否则，你恐怕得另找工作了。”

    还有一个由eye 这个字组成的、非常有用的习惯用语是eye-opener. Eye-opener
是一个字。

    Eye-opener有两个意思，一个是表示惊奇，就像下面这个女子所表达的情绪
：

    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.
这个被抛弃的妻子说：“当然，约翰和我是有一些矛盾，就像大多数夫妻一样。

    但是，我一直认为我们的婚姻是有牢固基础的。所以，当我打开他留在厨房
桌上的信，知道他和他以前大学里的女朋友出走了的时候，我真是非常惊奇。“

    Eye-opener的另一意思是：开阔了眼界。请听下面这个例子：

    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.
这句话的意思是：“看到宇航员在登上月球时拍的那些有关地球的彩色照片真是
开了眼界。我从来也不知道我们的地球在空间是这么美丽、这么孤单。”
