高 等 教 育

强和弟弟都接到了名牌大学的录取通知书。强用借来的钱送走了弟弟,就随本家哥去沿海一个港口城市打工。

那城市很美,强的眼睛就不够用了。本家哥说,不赖吧?强说,不赖。本家哥说,不赖是不赖,可总归不是自各儿的家,人家瞧不起咱。强说自各儿瞧起自各儿就行。

强和本家哥在码头的一个仓库给人家缝补篷布。强很能干,做的活精细,看到丢弃的线头碎布也给拾起来留作备用。

那夜暴风骤起,强从床上爬起来,冲到雨帘中。本家哥劝不住他,骂他是戆蛋。

在露天仓垛里,强察看了一垛又一垛,加固被掀动的篷布。待老板驾车赶过来,他已成了个水人儿。老板见所储物资丝毫无损,当场就要给他加薪,他就说不啦,我只是看我修补的篷布牢不牢。

老板见他如此诚实,就想把另一个公司交给他,让他当经理。强说我不行,让文化高的人干吧。老板说我看你行——比文化高的是人身上的那种东西!

强就当了经理。

公司刚开张,需要招聘几个大专以上文化程度的年轻人当业务员,就在报纸上做了广告。本家哥闻讯赶来,说给我弄个美差干干。强说,你不行。本家哥说,看大门也不行吗?强说,不行,你不会把这里当成自各儿的家。本家哥脸涨得紫红,骂道,你真没良心。强说,把自各儿的事干好才算有良心。

公司进了几个有文凭的年轻人,业务红红火火地开展起来。过了些日子,那几个受过高等教育的年轻人知道了他的底细,心里就起毛说,就凭我们的学历,怎么窝在他手下?强知道了并不恼,说,我们既然在一起儿共事,就把事办好吧,我这个经理的帽谁都可以戴,可有价值的并不在这顶帽上……

那几个大学生面面相觑,就不吭声了。

一外商听说这个公司很有发展前途,想洽谈一项合作项目。强的助手说,这可是条大鱼哪,咱得好好接待。强说,对头。

外商来了,是位外籍华人,还带着翻译、秘书一行。

强用英语问,先生,会汉语吗?

那外商一愣,说,会的。强就说我们用母语谈好吗?

外商就道了一声“OK”。谈完了,强说,我们共进晚餐怎么样?外商迟疑地点了点头。

晚餐很简单,但有特色,所有的盘子都尽了,只剩下两个小笼包子。强对服务小姐说,请把这两个包子装进食品袋里,我带走。虽说这些话很自然,他的助手却紧张起来,不住地看那外商。那外商站起来,抓住强的手紧紧握着,说,OK,明天我们就签合同!

事成之后,老板设宴款待外商,强和他的助手都去了。

席间,外商轻声问强,你受过什么教育?为什么能做得这么好?

强说,我家很穷,父母不识字。可他们对我和弟弟的教育是从一粒米、一根线开始的。后来我的父亲去世,母亲辛辛苦苦地供我们上学。她说俺不指望你们高人一等,能做好自各儿的事就中……

在一旁的老板眼里渗出亮亮的液体,他端起一杯酒,说,我提议敬她老人家一杯——你受过人生最好的教育——把母亲接来吧!

阅读理解。

     It's no secret that the world has become a very fastpaced place. Free time has been replaced by

cyber (网络的) time to the point where my family feels the need to comment on my presence at the

dinner table. With all these options and distractions (使人分心的事) it can be hard to spend quality

time with the people you love.

     My Dad and I have always worked around this. Over years we've learned how to watch in silence

while enjoying each other's company and by now we know what to comment on during the commercials.

     Once we were watching one of our favourite shows. At the commercial he turned to me and asked

if I liked going to school.

     I thought about the question for a few moments before admitting that I did.

     "Do you look forward to going?"

     This question seemed easier to answer, but I thought it over.

     "Not all the time. Sometimes, there are classes that I dread. But then there are people I want to see

or things I want to do, so I guess it evens out."

     Dad nodded.

     "You see these characters on the show? They like going to work. They look forward to it. They are

so idealistic that they go to work every day, believing they can change the world. That's why we like to

watch them."

     I thought about what he was saying.

     "Do you look forward to going to work?" I asked.

     Dad paused.

     "I honestly don't think about it. It's not something I anticipate or dread. It's just something that I do.

I always looked forward to going to school, though. I wanted to learn. Now that I think about it, when

I first started working I did look forward to it. That's what's important. Do something that you enjoy

doing. Do something that you will look forward to. Otherwise, what's the point?"

     Now I have learned that sometimes it's not the length of the talk that's important but what's said during

the talk. It is still possible to have quality time during a commercial break.

1. The father quoted the characters on the show to say that a person should have ________. 

A. dream     

B. belief

C. doubt                              

D. love

2. According to the passage, why doesn't the boy want to go to school?

A. He is afraid of being made fun of.                  

B. He has something important to do.

C. He loses interest in some classes.                    

D. He falls behind other classmates.

3. The underlined word "point" means ________.  

A. mark              

B. topic

C. lesson            

D. goal

4. What's the main idea of this passage? 

A. Children can have quality time with their parents.

B. Children feel happy when talking with parents.

C. Parents and children can enjoy the same TV show.

D. Children are unwilling to stay with their parents.
