19．-Bob is always complaining about not having any money．
-The problem is that he doesn't work hard and never ____．（　　）
A．doesB．hadC．hasD．did

分析 ----Bob 總是抱怨沒錢．
---問題是他不努力工作，也從來沒有什么錢．

解答 答案：C
由于"that he doesn't work hard and never ____"用于系動詞is 之后；故本句是表語從句，其中，由并列連詞and連接的兩個謂語在時態(tài)上應保持一致，故此處應使用一般現(xiàn)在時，描述了Bob的現(xiàn)狀，即：他不努力工作，也沒有錢．故選C

點評 本題考查了一般現(xiàn)在時的用法．在本題中，由于此處的兩個謂語是由并列連詞and連接連在一起的，故前后的時態(tài)應保持一致；另外，在做類似的時態(tài)題時，還可以根據(jù)句意判斷出動作發(fā)生的時間或者根據(jù)問句以及答語的時態(tài)，來確定空缺處的時態(tài)；最后，應熟練掌握一般現(xiàn)在時態(tài)的意義及用法．

14．閱讀下面的短文，然后按照要求寫一篇150詞左右的英語短文．
Education does Count（excerpt）-Bill Gates
Hundreds of students send me e-mail each year asking for advice about education．They want to know what to study，or whether it's OK to drop out of college since that's what I did．
My basic advice is simple and heartfelt．"Get the best education you can．Take advantage of high school and college．Learn how to learn．"
It's true that I dropped out of college to start Microsoft，but I was at Harvard for three years before dropping out-and I'd love to have the time to go back．As I've said before，nobody should drop out of college unless they believe they face the opportunity of a lifetime．And even then they should reconsider．
In my company's early years，we had a bright part-time programmer who threatened to drop out of high school to work full-time．We told him no．
Quite a few of out people didn't finish college，but we discourage dropping out．
Having a diploma certainly helps somebody who is looking to us for a job．
There's not a perfect correlation between attitudes in high school and success in later life，of course．But it's a real mistake not to take the opportunity to learn a huge range of subjects，to learn to work with people in high school，and to get the grades that will help you get into a good college．
【寫作內(nèi)容】
1．以約30個詞概括這段短文的內(nèi)容；

   （1）為什么有些學生想中途放棄學業(yè)去創(chuàng)業(yè)；
（2）你認為讀書與事業(yè)之間的關系是怎樣的；
（3）你自己有何打算．
【寫作要求】
1．在作文中可以使用自己親身的經(jīng)歷或虛構的故事，也可以參照閱讀材料的內(nèi)容但不得直接引用原文中的句子；
2．作文中不能出現(xiàn)真實姓名和學校名稱．
[評分標準]
概括準確，語言規(guī)范，內(nèi)容合適，篇章連貫．
