Question

【题目】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(倾向) to age more slowly than a man’s. Others think that a man’s body cells have a tendency to age more quickly. 【5】

【1】A

【2】G

【3】D

【4】C

【5】E

【解析】本文论述女性比男性寿命长的原因。

【1】A 文章后面说they can expect to live six or seven years more than men．她们比男人可以多活六到七年，可以推测前面应该讲的是女人．故选A．

【2】G 文章前一句说One important biological factor that helps women live longer is the difference in hormones between men and women．男女荷尔蒙不同；后一句说women produce hormones that are involved in fertility女性的荷尔蒙与生育有关，可以知道这里讲的应该是荷尔蒙的问题．故选G．

【3】D 前面说到These hormones also have a positive effect on the heart and blood flow．荷尔蒙对心脏和血液有好处；后面说They help the body defend itself against some kinds of infections．它们还可以对抗感染，可以推测这里讲的应该是荷尔蒙保护身体的另外一种方式．故选D．

【4】C 后面一句是Scientists are still not exactly sure how genes influence aging科学家们还不清楚基因是如何对抗衰老的，可以知道前面应该说的是基因．故选C．

【5】E 文章最后说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．女性身体细胞老化得比男人慢，或者说男人的细胞必女人老化得快．这两种可能性都得到了目前研究的支持，故选E．
