题目内容

14．________on the fact，I firmly believe that the report should be reliable．（　　）

A．

Basing

B．

To be base

C．

Based

D．

To base

分析我坚信以事实为根据的这份报告应该是可信的．

解答答案：C
句中有逗号分隔，没有连词，要用非谓语动词；base与report之间构成动宾关系，要用过去分词来构成，即the report is based on the fact；句意表达的是事实，不能用不定式来表示．故选C．

点评过去分词是非谓语动词的一种，用法很灵活，分为简单式done（表示与谓语同时或几乎同时发生的动作）；完成式having been done（表示先于谓语的动作）．学习时，要把握其用法特征：表示被动和完成．同时还要注意区分现在分词和不定式．

5．Fortunately（ fortunate），the storm did only a little damage to the crops．

9．Blind tasting is a very strange activity．Contrary to what many people imagine，it has nothing to do with blindfolds．It involves tasting a wine without seeing the label （商标） and it can deliver shocking surprises．I tasted seven champagnes （香槟） blind with a group of professionals recently．There was a shock when they discovered the wine most of them preferred carried a label they regarded as their least favorite．That sort of result is especially common with champagne，the most image-driven rather than quality-driven wine of all．But it happens all the time when wine is tasted blind．
Because I'm interested in how wines really taste instead of how I think they should，I taste wine blind as often as I can，especially when assessing similar young wines．But blind tasting when you know absolutely nothing about the wine in front of you is something completely different．The most difficult Master of Wine exams include three sessions during which you have a dozen glasses in front of you and nothing more helpful than a printed exam paper asking you to identify （鉴定） each wine as closely as possible，and assess its quality．
Now that the MW is behind me，I taste wine completely blind only very rarely，and never in public．So my blind tastings these days are round the dinner table with good friends and once a year when I act as a judge，with Hugh Johnson，in the Oxford vs Cambridge wine-tasting competition．This is the most extraordinary match，always held before the Boat Race but taken just as seriously nowadays．This year's taste-off took place at the end of last month，as usual in the Oxford and Cambridge Club on Pall Mall in London．
25．Which of the following is true about Blind tasting？D
A．Blind tasting is the professional way to identify a wine．
B．Blind tasting usually has the right result．
C．Blind tasting means tasting a wine with one's eyes covered．
D．Blind tasting is tasting a wine without seeing the label．

C．The writer made no mistakes．
D．Champagnes can not be tasted blind．
27．What can we infer from the last paragraph？B
A．The Boat Race is taken more seriously than the wine race．
B．The Oxford v Cambridge wine-tasting competition is held annually．
C．I didn't act as a judge last year．
D．Pall Mall is chosen as the competition place for the first time．

6．Mobile phone （手机） has become a problem for middle schools．Some middle schools in Australia have banned （禁止） students from carrying mobile phones during school hours．

Many teachers said students should not have mobile phones at school，but if there was a good reason，they could leave their phones at school office．They also said there were many reasons why the students should not have mobile phones at school：they were easy to lose and were a distraction from studies．
Many people say that they understand why parents would want their children to have phones，but they think schools should let the students know when they can use their mobile phones．

3．Not all memories are sweet．Some people spend all their lives trying to forget bad experiences．Violence and traffic accidents can leave people with terrible physical and emotional scars．Often they relive these experiences in nightmares．
Now American researchers think they are close to developing a pill，which will help people forget bad memories．The pill is designed to be taken immediately after a frightening experience．They hope it might reduce，or possibly wipe out，the effect of painful memories．
In November，experts tested a drug on people in the US and France．The drug stops the body releasing chemicals that fix memories in the brain．So far the research has suggested that only the emotional effects of memories may be reduced，not that the memories are wiped out．They are not sure to what degree people's memories are affected．
The research has caused a great deal of argument．Some think it is a bad idea，while others support it．Supporters say it could lead to pills that prevent or treat soldiers'troubling memories after war．They say that there are many people who suffer from terrible memories．
"Some memories can ruin people's lives．They come back to you when you don't want to have them in a daydream or nightmare．They usually come with very painful emotions，"said Roger Pitman，a professor of psychiatry at Harvard Medical School．"This could relieve a lot of that suffering．"
But those who are against the research say that maybe the pills can change people's memories and changing memories is very dangerous because memories give us our identity．They also help us all avoid the mistakes of the past．
"All of us can think of bad events in our lives that were terrible at the time but make us who we are．I'm not sure we want to wipe those memories out．"Said Rebcca Dresser，a medical ethicist．
24．The passage is mainly aboutD
A．a new medical invention
B．a new research on the pill
C．an argument about the research on the pill
D．a way of wiping out painful memories
25．The drug tested on people canA

A．Some memories can ruin people's lives．
B．People want to get rid of bad memories．
C．The pill will reduce people's sufferings from bad memories．
D．Experiencing bad events makes us different from others．
27．We can infer from the passage thatB
A．the pills will certainly stop people's emotional memories
B．people doubt the effect of the pills
C．taking the pill will do harm to people's physical health
D．the pill has already been produced and used by the public in the US．

4．If you think that running marathons will help you live a long and healthy life，new research may come as a shock．According to a recent scientific study，people who do a very strenuous workout are as likely to die as people who do no exercise at all．
Scientists in Denmark have been studying over 1，000joggers （慢跑者）and non-joggers for 12years．The death rates from the sample group indicate that people who jog at a moderate pace two or three times a week for less than two and a half hours in total are least likely to die．The best speed to jog at was found to be about 5miles per hour．The research suggests that people who jog more than three times a week or at higher speeds of over 7mph die at the same rate as non-joggers．The scientists think that this is because strenuous exercise causes structural changes to the heart and arteries（动脉）．Over time，this can cause serious injuries．
Peter Schnohr，a researcher in Copenhagen，said，"If your goal is to decrease risk of death and improve life expectancy（寿命），jogging a few times a week at a moderate （适度的）pace is a good strategy．Anything more is not just unnecessary，and it may be harmful．"
The implications （暗示）of this are that moderate forms of exercise such as tai chi，yoga and brisk （轻快的）walking may be better for us than"iron man"events，triathlons and long-distance running and cycling．According to Jacob Louis Marott，another researcher involved in the study，"You don't actually have to do that much to have a good impact on your health．And perhaps you shouldn't actually do too much"．
