11.Millions of dollars'worth damage______ by the tornado(龙卷风) which swept across the south of America last night.(  )
A.had been causedB.will be causedC.was causedD.has been caused

分析 成千上万美元的价值毁坏由龙卷风产生了,这次龙卷风昨晚席卷了美国南部.

解答 答案:D 考查时态辨析.虽然龙卷风发生在昨晚,但对现在产生了影响,即产生了成千上万美元的价值毁坏,要用现在完成时态.A项是过去完成时态,表示产生的毁坏在昨晚之前;B项是一般将来时态,这里没有表示将来的时间;C项是一般过去时态,表示产生的毁坏与现在没有关系,这显然不符合题意.

点评 解答此类问题要了解各种时态的基本含义,并区别各种时态之意的差异,了解某些时态的特殊用法,然后结合语境选择正确答案.

16.Hi,Nancy!Thank you for writing to me.I enjoy getting letters from students in China and I'll be happy to exchange letters with you.
The first thing I want to tell you is that if the boys are calling you names it is their fault,not yours.Boys,at your age,are different from girls.They are trying to prove that they are manly and they often do this by choosing someone who can't really fight back.This is,of course,wrong but it happens and it is generally referred to as bullying.In general,the boys know they are bigger and stronger than you are,so they can make fun of you and make you cry and then laugh about it.If you let them see that they are hurting you,they will only do it more.It isn't that they want to hurt you; they simply want to make themselves feel superior.It's stupid but it is very common.
The best way of getting the boys to stop calling you names is to simply ignore them,knowing that the names can't hurt you and that the boys are being stupid.If you can laugh at them,they will get tired of trying to make you cry.Then they will give up and begin to notice you as a young woman.I suspect some of them actually like you and are laughing at you just to get your attention.Again,it's stupid but it happens.In reality,you can control this situation by not letting them see you getting hurt.Laugh at them,tell them they are acting like children and they should grow up and then walk away with your head held high.
One more thing,Nancy.It is very important that you stop hurting yourself.If someone else hurts you it is bad enough but you shouldn't make it worse by then hurting yourself.Even sticking a pen into your finger can cause an infection and give you a lot of trouble and besides,it hurts.The next time you are frustrated by a bunch of stupid boys,write to me.You and I can talk about anything you like,about China,about Canada,about travel,anything.Having a conversation with me is better than sticking holes in your fingers,as least I hope it is.
I wish you all the best and I hope to hear from you again soon.If you get a chance,please send me your picture.
Best wishes.
Brad

55.Which of the following is not the reason why boys make fun of Nancy?A
A.Nancy is a naughty girl
B.They want to prove they are manly
C.They want to make themselves feel superior
D.Some boys like Nancy and want to get her attention
56.The underlined word"bullying"in Paragraph 2meansB.
A.to pity a weaker person
B.to frighten or hurt a weaker person
C.to learn from a weaker person
D.to help a weaker person
57.According to Brad's advice,the next time the boys call Nancy names,she should do the following exceptD.
A.to ignore them
B.to laugh at them
C.not to let them see her getting hurt

3.I worked as a manager in a company for a number of years.I liked my job,and was doing well there,but our company was bought by a large company and most of the managers at our place lost their jobs.That was when I decided to do something I'd always wanted to do---become a freelance(自由撰稿的) writer.Changing professions has meant that my lifestyle has changed in a number of ways.
The main difference for me now is that I have a much more flexible( 灵活的) schedule.I work about as much as I did before---between 45and 50hours a week---but my schedule is much less rigid (刻板的) than it used to be.Before,I worked from 8a.m.to 5p.m.every day,with a few extra hours on weekends.Now,however,I work when I feel like it.For instance,sometimes I work until midnight or 2a.m.,then sleep until noon.I really prefer this kind of schedule.It seems more natural to me.
I alse decided that it was about time I began to pay more attention to my health.While I was working as a manager,I never exercised.I already felt tired after work,so I just came home in the evening and watched TV.However,last year I joined a health club and began to do regular exercise.As a result I have lost over 10pounds and I feel much better.I've also started to eat more healthfully.I used to eat a lot of fast food,but now I do my own shopping.I buy lots of fruits and vegetables and cook them at home.
Of course,not all the changes have been that east.For example,I don't feel as safe financially as I used to.When I was working as a manager,I never worried much about money.I could always count on getting my paycheck every two weeks.Working freelance,I don't have a regular paycheck.So now I have to make sure that there's enough money until the next check arrives.
All in all,I really like my current lifestyle.Of course,that doesn't mean I'll never want to have a"regular"job.But for me,at least,it suits me.

71.The author decided to become a freelance writer becauseA.
A.he had always liked writing
B.he hadn't liked to work in the company
C.the boss didn't like him
D.the boss had another person to do the job
72.What is the main difference the job change brought to the author?C
A.That he doesn't need to work hard.
B.That he can earn much more money.
C.That he can change his schedule as he likes.
D.That he can watch TV as long as he likes.
73.What is his chief problem now?D
A.He has no job to do.
B.He must work harder than before.
C.His health has changed worse than before.
D.He has to worry about money.
74.At the end of the passage,the author indicates thatB.
A.he wants to have a regular job
B.he is not going to change his lifestyle in the near future
C.he wants to change his lifestyle in the near future
D.he must change his job to earn more money.
75.Which of the following is True according to the passage?B
A.The author likes to work in the company very much.
B.The author's lifestyle has changed in a number of ways.
C.The author doesn't like to do exercise.
D.The author does want to change his job to earn more money.
