20.-May I go home now?
-____________you've finished your work,you may.(  )
A.Even thoughB.Every timeC.Now thatD.If only

分析 --我现在可以回家了吗?
--既然你已经完成了你的工作,你可以.

解答 答案C.
even though"尽管,即使",引导让步状语从句;every time"每当",引导时间状语从句.now that"既然",用法等于since,引导原因状语从句.if only"但愿,要是",用于使用虚拟语气的句子中.分析可知前后两句话之间是逻辑上的"因果"关系,再结合句子所表达的意思可知答案选C.

点评 本题考查从属连词的用法.连词的用法辨析,要注意分析主从句之间的逻辑关系,再确定相应的连词,同时注意不同的连词的语义及用法区别.

12.阅读下面的短文,然后按照要求写一篇150词左右的英语短文.
Good morning,ladies and gentlemen.This is Li Hua from Senior Three.I'm here today to share with you a good lesson from an overseas Chinese student living in Germany.It is a true story.
After years of hard work,this Chinese student graduated with amazing academic achievements.Everyone thought he was going to get a good job easily and have a bright future.But to his disappointment,he was not even allowed the chance for an interview!The third time he was turned down,he couldn't help telephoning the company to ask why they didn't want him.The answer was simple."We don't hire dishonest people in Germany."
What was wrong you might wonder?The truth is,shortly after he arrived in Germany,this clever student found that it was easy to skip buying subway tickets.So,to save money,he often went without a ticket.As a result,he had been caught without a ticket in the subway three times.
From this story,we learn that we may get short-term benefits by dishonest means,but the truth will come out sooner or later and the cost is high.So remember:honesty is the best policy.
That's all for my speech.Thank you!
