单选题
A study by a group of dentists has concluded that regular use of a certain brand of mouthwash is as effective as flossing in preventing gum disease. The mouthwash company has released a television ad suggesting that people who do not like flossing can now rely solely on mouthwash and brushing to maintain good dental health. A leading manufacturer of dental floss brought a lawsuit against the mouthwash company demanding that the advertisement be discontinued on the grounds that it is misleading. Which of the following, if true, provides the strongest support for the dental floss company’s claim that the advertisement is misleading?
A
The dental floss manufacturer is concerned that it will lose market share in the dental health market because the advertisement encourages people to switch from dental floss to mouthwash.
B
The dental floss company claims in its own advertisements that brushing and flossing after every meal is the most effective way to maintain good dental health.
C
Although mouthwash is an effective deterrent to gum disease, it is less effective than dental floss at removing plaque and preventing cavities between teeth.
D
Per usage, mouthwash is three times more expensive than dental floss, if the recommended amounts of both products are used.
E
The dentists who conducted the study on the effectiveness of mouthwash in preventing gum disease obtained their funding for the study from a company that manufactures mouthwash.

US to Start $3.2 Billion Child Health Study in January
A study that will cost$3.2 billion and last more than two decades to track the health of 100,000 US children from before birth to age 21 will be launched in January,US health officials said on Friday.
Officials from the US government's National Institutes of Health said they hope the study,to be conducted at 105 locations throughout the United States,can help identify early-life influences that affect later development,with the goal of learning new ways to treat or prevent illness.
The study will examine hereditary（遗传的）and environmental factors such as exposure to certain chemicals that affect health.
Researchers will collect genetic and biological samples from people in the study as well as samples from the homes of the women and their babies including air,water,dust and materials used to construct their residences,the NIH said.
Officials said more than $200 million has been spent already and the study is projected to cost$3.2 billion.
"We anticipate that in the long term（从长远来说）,what we learn from the study will result in a significant savings in the nation's health care costs,"Dr. Duane Alexander,who heads the NIH's Eunice Kennedy Shriver National Institute of Child Health and Human Development,told reporters.
The study will begin in January when the University of North Carolina and the Mount Sinai School of Medicine in New York start signing up（签订协议）pregnant women whose babies will then be followed to age 21.
Some of the early findings will be about factors behind pre-term birth（早产）,which has become more common in recent years,according to Dr. Peter Scheidt of the NIH,who heads the study.
The people taking part will be from rural,urban and suburban areas,from all income and educational levels and from all racial groups,the NIH said.The aim of the study is to find new ways to______.
A:conduct research
B:track public health
C:prevent or treat illness
D:speed up development答案：C解析：短文的第二段提到了此项研究的goal，即aim，这便是learning new ways to treat or prevent illness。
A、B、C三项在短文的第四段都有提及。D项不正确，应该是samples from the homes of the women and their babies including air,water,dust and materials used to construct their residences（参加研究的妇女及其婴儿家中的空气与水等物质）。
短文的第六段说到，预计从长远的角度讲，此项研究将节约大笔国家卫生保健费用。
短文的第一段及倒数第三段都说到，这些婴儿将从出生前一直被跟踪到 21岁。
A、B、C三项在短文的最后一段都有提及，而D是错误的，因为研究对象都是怀孕的妇女，不是所有年龄段的人们。 -

The study found a link between blue light 12 --blue light is 13 by smartphones and tables--and increasedhunger. It found that exposure to the light increases hunger levels for severalhours and even increases hunger levels 14 eating a meal.
Results of the US study show thatblue-enriched light exposure, compared with 15 light exposure, was 16 with an increase in hunger that began 15minutes after light onset and was still present almost two hours after themeal. Blue light exposure has also already been shown to decreased 17 in the evening, increasing the risk ofinsomnia.
Study co-author Ivy Cheung, of NorthwesternUniversity in Chicago, said, "A single three-hour exposure toblue-enriched light in the evening 18 impacted hunger andglucose metabolism." "These results are important because theysuggest that 19 environmental light exposure for humansmay represent a novel 20 of influencing food intake patterns andmetabolism."
The study group 21 10 healthy adults with regular sleep and eating schedules who received
22 carbohydrate-rich meals. They completed afour-day trial 23 dim light conditions, which involvedexposure to less than 20 lux during 16 hours 24 and less than three lux duringeight hours of sleep. On day three they were exposed to three hours of 260 lux,blue-enriched light starting 10.5 hours after waking up, and the effects werecompared with dim light exposure on day two.
Ms Cheung said more research is needed todetermine the 25 of action involved in the relationshipbetween light exposure, hunger and metabolism.A.consisted
B.composed
C.concluded
D.comprised答案：D解析：考查动词辨析。consist“由……组成，包括”，与of连用；compose“包括”，一般用于be composed of；conclude“推断出，总结”；comprise“包括，由……组成，构成”，后面可接宾语。故选D。 -

Bhas enabled
Cto enable
Denabling
正确答案： A解析：
句意：公共图书馆的扩建使我们能给赞助人提供更多房间供其进行小组学习。
空格前为句子的主语，此句缺少谓语，因此要选择谓语，所以非谓语动词to enable和enabling不能选，enable意为“使能够，使成为可能”，具有使动意义的动词，其前不能加was，所以应该用has enabled。
