Question

Researchers have found more evidence that suggests a relationship between races and rates of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.
Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2,000 people in the study developed lung cancer.
Researchers say genetics might help explain the racial and ethnic differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference.
African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer.
Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine."

A．Whites—Native Hawaiians

B．Africans—Americans—Latinos

A．the larger amount of smoking than white people

B．the living style or habit of the blacks

C．the depth of cigarette smoke into their lungs

D．the physical strength to react to cigarette smoke

小題3:People in the new study are made up of _____.

A．heavy smokers in America	B．the black and white people
C．the Asians and Hawaiians	D．smokers and non-smokers

小題4:The production of BiDil referred to in the last paragraph is to _____.

A．explain different races react to some diseases differently

B．tell the readers that racial differences exist in smokers

C．show a big step people have taken in the medicine area

D．support the idea that it is easy for blacks to have cancers

試題分析：本文簡(jiǎn)述了肺癌和種族的關(guān)系，同時(shí)進(jìn)一步說(shuō)明同一種疾病對(duì)不同的種族也許會(huì)有不同的影響。
小題1:B 排序題。根據(jù)第一段2,3行A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.說(shuō)明B的順序正確。
小題2:C 推理題。根據(jù)第四段But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer. 說(shuō)明肺部吸入的煙的程度影響決定了人們患癌癥的可能性大小。故C正確。
小題3:D 細(xì)節(jié)題。根據(jù)第二段3,4行They included present and former smokers and people who never smoked說(shuō)明接受調(diào)查的是中有抽煙的也有不抽煙的。故D正確。
小題4:A 推理題。最后一段的中心思想是第一句Scientists know that some diseases effect different groups differently.下面所列舉的例子正是為了解釋這個(gè)中心思想，故A的說(shuō)法正確。
點(diǎn)評(píng)：本文簡(jiǎn)述了肺癌和種族的關(guān)系，同時(shí)進(jìn)一步說(shuō)明同一種疾病對(duì)不同的種族也許會(huì)有不同的影響。此類文章的最大的障礙是詞匯以及考生對(duì)閱讀內(nèi)容的不熟悉，需要考生在閱讀的時(shí)候有足夠的耐心，同上抓住文章的中心，不要受其他信息的影響。要根據(jù)題目及選項(xiàng)以及文章的上下文串聯(lián)合理的判斷推理。
