题目内容

14．Language experts claim that children _________ to the English-speaking environment will pick up English quickly．（　　）

	A．	being exposed		B．	having been exposed
	C．	to be exposed		D．	exposed

分析语言专家宣称身处英语语言环境中的儿童会在不知不觉中快速学会英语．

解答答案：D 句中expose作children的后置定语；expose sb to sth让自己暴露在某物下，句中expose与children构成动宾关系，且句意表达的是客观事实，要用表示被动的过去分词．故选D．

点评过去分词是非谓语动词的一种，用法很灵活，分为简单式done（表示与谓语同时或几乎同时发生的动作）；完成式having been done（表示先于谓语的动作）．学习时，要把握其用法特征：表示被动和完成．同时还要注意区分现在分词和不定式．

"This is your suspect，how would you recognize him？"
The first blonde answers，"That's easy．We'll catch him fast because he only has one eye!"

while I check his file and I'll get back to you on that．"He  leaves the room and goes to his office，checks the suspect's file in his computer，and comes back with a beaming smile on his face．
"Wow!I can't believe it…it's TRUE!The suspect does in fact wear contact lenses．Good
work!How were you able to make such an acute observation？"
"That's easy，"the blonde replied．"He can't wear regular glasses because he only has one eye and one ear．"

9．阅读下面短文，并按照题目要求用英语回答问题．
Sleeplessness in Seattle？Hardly．West Virginia is where people are really staying awake，according to the first government study to monitor state-by-state differences in sleeplessness．West Virginians'lack of sleep was about double the national rate，perhaps a side effect of health problems such as obesity（肥胖），experts said．
Nearly I in 5 West Virginians said they did not get a single good night's sleep in the previous month．The national average was about 1 in l 0，according to a federal health survey．Tennessee，Kentucky and Oklahoma also were notably above average with nearly 1 in 7 people reporting in a lack of sleep．In contrast，North Dakota was below average，with only 1 in 1 3 reporting that degree of sleeplessness．Health officials do not know the exact reasons for the differences．
In．the survey，people weren't required to answer the question why they were not able to get enough rest or sleep．But experts noted several possible explanations：West Virginia ranks at or near the bottom of the nation in several important measurements of health，including obesity，smoking，heart disease and the proportion of adults with disabilities．
Studies have increasingly found that sleeping problems often occurred among people with certain health problems，including obesity．"You would expect to see poorer sleep within a chronically（慢慢地） diseased population"，noted Dr Ronald Chervin，a sleep disorders expert in University of Michigan．
Financial stress and work shifts（倒班）can play roles in sleeplessness，too，Chervin added．He suggested those may be contributing factors in West Virginia，an economically depressed state with tens of thousands of people working in coal mining．
The report was based on results of an annual telephone survey of more than 400，000 Americans，including at least 3，900 in each state．The survey did not include people who use only cellphones．
56．What is the main idea of Paragraph 1？（No more than 15 words．）
West Virginians suffer from lack of sleep the most perhaps due to health problems．
57．What does the underlined word"notably"in Paragraph 2 mean？（No more than 3 words．）Highly
58．What was the possible reason for the high rate of sleeplessness in West Virginia according to Paragraph 3？（No more than 12 words．）West Virginia had a low level of several important measurements of health．
59．List three factors that contribute to sleeplessness based on the passage．（No more than 8 words．）
（1）being too fat（2）financial stress（3）work shifts
60．How was the research carried out？（No more than 10 words．）By interviewing over 400，000 Americans on the telephone．．
