Smoking, ____ some smokers, might ease their anxiety sometimes, but ____ the addiction caused by their constant practice, it is really hard to give up.

A. according to; due to    B. according to ;because 

C. as to; since             D. thanks to;if

A


解析:

該題介詞短語意義辨析。首先應(yīng)從句子結(jié)構(gòu)入手，找出句子的主要成分：Smoking might ease their anxiety but it is really hard to give up。其中的兩個介詞短語分別充當(dāng)狀語。因為句子中的addiction是被過去分詞短語修飾的名詞，因此它前面不能用連詞，只能用介詞；而且后的but分句表示轉(zhuǎn)折，因此只能選擇due to。本句的意思是：一些吸煙者認為，吸煙可能有時會緩解其緊張的情緒，但是，由于這種連續(xù)不斷的行為所形成的煙癮是很難戒掉的。

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."

1.Which of the following orders is from higher to lower risk of having lung cancer?

A．Whites—Native Hawaiians

B．Africans—Americans—Latinos

C．Asians—Native Hawaiians

D．Africans—Americans—Native Hawaiians

2.Researchers agree that it is _____ that may probably determine black people’s risk of lung cancer.

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

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

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
