6.Both men and women are living longer these days in industrialized countries.(36)A In general,they can expect to live six or seven years more than men.One reason for this is biological.
One important biological factor that helps women live longer is the difference in hormones between men and women.(37)G Between the ages of about 12and 50,women produce hormones that are involved in fertility(生育能力).These hormones also have a positive effect on the heart and blood flow.In fact,women are less likely to have high blood pressure or to die from heart attacks.
(38)DThey help the body defend itself against some kinds of infections.This means that women generally get sick less often and less seriously than men.The common cold is a good example:women,on average,get fewer colds than men.(39)CScientists are still not exactly sure how genes influence aging,but they believe that they do.Some think that a woman's body cells have a tendency(向) to age more slowly than a man's.Others think that a man's body cells have a tendency to age more quickly.(40)E

A.However,women,on average,live longer.
B.The biological factor plays an important part.
C.Women are also helped by their female genes.
D.The female hormones also protect the body in another way.
E.Recent research seems to support both of these possibilities.
F.Therefore,women are more healthy than men and can live a better life.
G.Hormones are chemicals which are produced by the body to control carious body functions.

分析 文章是一篇科技報道,講述了女人比男人長壽的原因.現(xiàn)代社會人們普遍比過去長壽了,但女人更長壽.其中一個重要的原因是生物因素:女人和男人的生物荷爾蒙不同,女性因為生育的原因,分泌的荷爾蒙對心臟和血液都有良性的影響,讓女人更少受高血壓和心臟病的困擾.同時,女性荷爾蒙還可以對抗感染,就連普通的感冒,女人也比男人更有抵抗力.科學(xué)家們現(xiàn)在還沒弄清楚基因是如何影響人肌體的老化,但可以肯定的是女性的身體細(xì)胞老化的速度比男人慢.

解答 36.A 文章后面說they can expect to live six or seven years more than men.她們比男人可以多活六到七年,可以推測前面應(yīng)該講的是女人.故選A.
37.G 文章前一句說One important biological factor that helps women live longer is the difference in hormones between men and women.男女荷爾蒙不同;后一句說women produce hormones that are involved in fertility女性的荷爾蒙與生育有關(guān),可以知道這里講的應(yīng)該是荷爾蒙的問題.故選G.
38.D 前面說到These hormones also have a positive effect on the heart and blood flow.荷爾蒙對心臟和血液有好處;后面說They help the body defend itself against some kinds of infections.它們還可以對抗感染,可以推測這里講的應(yīng)該是荷爾蒙保護(hù)身體的另外一種方式.故選D.
39.C 后面一句是Scientists are still not exactly sure how genes influence aging科學(xué)家們還不清楚基因是如何對抗衰老的,可以知道前面應(yīng)該說的是基因.故選C.
40.E 文章最后說Some think that a woman's body cells have a tendency(向) to age more slowly than a man's.Others think that a man's body cells have a tendency to age more quickly.女性身體細(xì)胞老化得比男人慢,或者說男人的細(xì)胞必女人老化得快.這兩種可能性都得到了目前研究的支持,故選E.

點評 七選五是一類完成性閱讀.在題型上和完形填空很類似,不同之處在于一個是選詞,一個是選句子.解題時,要在理解文章整體的情況下,充分考慮語境和空格前后的句子,注意句子之間的邏輯聯(lián)系.尤其要學(xué)會把握信息詞(選項中出現(xiàn)的與文章中相同或相近的詞),快速準(zhǔn)確的選出最符合文章原意的答案.

1.El Nifio,a Spanish term for"the Christ child",was named by South American fisherman who noticed that the global weather pattern,which happens every two to seven years,reduced the amount of fishes caught around Christmas.El Nifio sees warm water,collected over several years in the western Pacific,flow back eastwards when winds that normally blow westwards weaken,or sometimes the other way round.
The weather effects both good and bad,are felt in many places.Rich countries gain more from powerful Nifio,on balance,than they lose.A study found that a strong Nifio in 1997 helped American's economy grow by 15 billion,partly because of better agricultural harvest,farmers in the Midwest gained from extra rain.The total rise in agricultural in rich countries in growth than the fall in poor ones.
But in Indonesia extremely dry forests are in flames.A multi-year drought (干旱)in south-east Brazil is becoming worse.Though heavy rains brought about by El Nino may relieve the drought in California,they are likely to cause surface flooding and other disasters.
The most recent powerful Nino,in 1997-98,killed around 21,000 people and caused damage worth $36 billion around the globe.But such Ninos come with months of warning,and so much is known about how they happen that governments can prepare.According to the Overseas Development Institute (ODI),however,just 12% of disaster-relief funding in the past two decades has gone on reducing risks in advance,rather than recovery and rebuilding afterwards.This is despite evidence that a dollar spent on risk-reduction saves at least two on reconstruction.
Simple improvements to infrastructure (基礎(chǔ)設(shè)施)can reduce the spread of disease.Better sewers (下水道)make it less likely that heavy rain is followed by an outbreak of the disease of bad stomach.Stronger bridges mean villages are less likely to be left without food and medicine after floods.According to a paper in 2011 by Mr Hsiang and co-authors,civil conflict is related to El Nino's harmful effects-and the poorer the country,the stronger the link.Though the relationship may not be causal,helping divided communities to prepare for disasters would at least reduce the risk that those disasters are followed by killing and wounding people.Since the poorest are least likely to make up for their losses from disasters linked to El Nino,reducing their losses needs to be the priority.

61.What can we learn about El Nino in Paragraph 1?D
A.It is named after a South American fisherman.
B.It takes place almost every year all over the world.
C.It forces fishermen to stop catching fish around Christmas.
D.It sees the changes of water flow direction in the ocean.
62.What may El Ninos bring about to the countries affected?C
A.Agricultural harvests in rich countries fall.
B.Droughts become more harmful than floods.
C.Rich countries'gains are greater than their losses.
D.Poor countries suffer less from droughts economically.
63.The data provided by ODI in Paragraph 4 suggest thatA
A.more investment should go to risk reduction
B.governments of poor countries need more aid
C.victims of El Nino deserve more compensation
D.recovery and reconstruction should come first
64.What is the author's purpose in writing the passage?D
A.To introduce El Nino and its origin.
B.To explain the consequences of El Nino.
C.To show ways of fighting against El Nino.
D.To urge people to prepare for El Nino.
