Question

【題目】Both men and women are living longer these days in industrialized countries. 【1】 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. 【2】 Between the ages of about 12 and 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.

【3】 They help the body defend itself against some kinds of infections. This means thatwomen 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.

【4】 Scientists are still not exactly sure how influence aging, but they believe that they do. Some think that a woman’s body cells have a tendency(傾向) to age more slowly than a man’s. Others think that a man’s body cells have a tendency to age more quickly. 【5】

Answer 1

【答案】

【1】A

【2】G

【3】D

【4】C

【5】E

【解析】本文論述女性比男性壽命長的原因。

【1】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．

【2】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．

【3】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．

【4】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．

【5】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．
