How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.

There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.

“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.

“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”

Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

71.The first paragraph is meant to__________.

A. ask some questions                        B. introduce the topic

C. satisfy readers’ curiosity                 D. describe an academic fact

【答案】B

【解析】通过两个问题引出话题。

72.Which of the following is true of James Watson？

A. He is strongly in favor of the present genetic tests.

B. He is more likely to suffer from Alzheimer’s disease.

C. He believes genetic mapping can help cure any disease.

D. He doesn’t want to know his chance of getting a disease.

【答案】D

【解析】根据第二段Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’。“James Watson要求如果他的基因表明他有很高的老年痴呆症的可能不要告诉他。”

73.According to Paragraphs 3 and 4, if a person is at a higher genetic risk, it is__________.

A. advisable not to let him know          B. impossible to hide his disease

C. better to inform him immediately      D. necessary to remove his anxiety

【答案】A

【解析】根据这两个自然段可知，如果你提前被告知你将来可能患某种可怕的疾病会mess you up。

74.The underlined part“freak out”in Paragraph 5 is closest in meaning to“_________”.

A. break down                     B. drop out            C. leave off            D. turn away

【答案】A

【解析】根据下文But的转折，以及no significant difference可知，freak out的意思是A（精神垮掉）。

75.The study led by Dr. Green indicates that people__________.

A. prefer to hear good news         B. tend to find out the truth

C. can accept some bad news              D. have the right to be informed

【答案】C

【解析】根据第五段内容 In fact, most people think they can handle it可知答案选C.

Don't blame genes for aging facial skin. A new study of twins suggests you can   1   those coarse(粗糙的) wrinkles, brown or pink spots, and dilated(膨胀的) blood vessels on too much time in the sun, smoking, and being overweight.

Because twins share genes, but may have  2  exposures to environmental factors, studying twins allows an, "opportunity to control for genetic susceptibility(敏感性)," Dr. Elma D. Baron, at Case Western Reserve School of Medicine in Cleveland, Ohio, and colleagues  3  in the latest issue of Archives of Dermatology.

Their analysis of environmental skin-damaging factors in 65 pairs of twins hints that skin aging is  4  more to environment and lifestyle than  5   factors.

But when it   6   skin cancer, the researchers say their findings support previous reports that   7  environment and genes affect skin cancer risk.

Baron's team   8   facial skin of 130 twins, 18 to 77 years old, who lived  9   in the northern Midwest and Eastern regions of the U.S. who were  10   the Twins Days Festival in Ohio in August 2002.

At this time, each of the twins also  11    reported how their skin burned or tanned  12    sunscreen(防晒霜), their weight, and their history of skin cancer, smoking, and alcohol drinking.

The study group   13   of 52 fraternal and 10 identical twin pairs, plus 3 pairs who were unsure of their twin status. Identical(同卵的) twins share all of their genes and fraternal twins share only about half.

From these data, the researchers  14  strong ties, outside of twin status, between smoking, older age, and being overweight, and having facial skin with evidence of environmental  15 

 16   contrast, sunscreen use and drinking alcohol appeared correlated with   17    skin damage.

Baron and colleagues say the current findings, which highlight ties between facial   18  and potentially avoidable  19   factors -- such as smoking, being overweight, and   20   overexposure to the sun's damaging rays -- may help motivate people to minimize these risky behaviors.
