【题目】 The real reason why prices ____ , and still are, too high is complex, and no short discussion can satisfactorily explain this problem.

A. were B. will be

C. have been D. had been

【答案】A

【解析】

试题分析:本题考查动词时态。

结合句意“过去价格太高,现在仍然太高的原因很复杂...”可知,此处 and 连接两个并列的系动词,后者是对现在事实的描述,为一般现在时;前者是对过去事实的描述,应用一般过去时,又主语 prices 为复数,故用系动词用 were,A项正确。will be 为一般将来时,have been 为现在完成时,had been 为过去完成时,均不符合句子时态。故正确答案为A。

Dear Mr.Zhang,

We have held a discussion whether it is good or not for a top student to share a desk with a slower student.Some are for the idea.It is well known that everyone had strengths as well as weaknesses.Although slower students are not good at lessons,they might do good in another fields.In addition,top students can help slower ones with their lessons, which benefit them too.However,others don't hold the same view.They think some slower ones are always making the trouble,such as break school rules.Besides,slower students often ask top students question,which affects our studies.

In my opinion,I support the idea so we can make progress together.

Yours,

Li Hua

【题目】A new research shows that in Britain more and more people are returning to the old tradition that the whole family has a meal at table. Worrying about the obesity(肥胖症) and breakdown of a family, people change their eating habits so greatly, according to analysis. They find the number of the family having a meal together increases by 5% from 2002 to 2004, and most people who have meals with their family come from the rich social class.

The new discovery makes doctors and the people struggling against obesity extremely excited. Giving up the tradition that the whole family have a meal together is exactly one of the reasons for a series of problems including children’s overweight. If a child has a meal in front of the television or the computer alone, he will often eat some fast food.

Jason Collins is one of the persons returning to the old tradition. Collins is a manager of a bake house. He finds after he gets used to having a meal at home with his child, the child becomes much more obedient(听话的). Dr. Jin is a child psychologist, and she expresses welcome to this result of the study. She says it can make parents have a very good chance to chat with the child when the whole family have a meal together.

1What makes people change their eating habit back to the old tradition in Britain?

A. Worrying about their children

B. Worrying about some social problems

C. Worrying about the living expense

D. Worrying about health and family problems
