15．A new report says there are now more obese people in the world than there are underweight people．Researchers from Imperial College London wrote the report．
The researchers examined health records from about 20million people for what they called the"world's biggest obesity study．"For the study，the researchers compared the body measurements of almost 20million adults．They found that from=1975to 2014，global obesity rates for men increased from 3.2percent of the population to 10.8percent．For women，it rose from 6.4percent to 14.9percent．The study found that more than 2.3percent of men and 5percent of women are considered severely obese．A severely obese individual has a body mass index （or BMI） of over 35kilograms per square meter．BMI is a way to measure a person's height compared to their weight．The study also found that about 1percent of men and 2percent of women are considered"morbidly （病態(tài)地） obese．"Such people have difficulty with simple activities because they are overweight．The researchers say there are now=55million morbidly obese adults worldwide．
Majid Ezzati is the chief writer of the report．He writes that"the number of people across the globe whose weight poses a serious threat to their health is greater than ever before．He adds that this epidemic （流行病） of severe obesity is too extensive to be dealt with just medications．He says coordinated global initiatives are needed to  tackle this crisis．These initiatives include looking at the"price of healthy food compared to unhealthy food，or taxing high sugar and highly-processed foods （深加工食品）．"
The researchers warn if the problem of obesity worsens，18percent of men and=21percent of women will be obese by 2025．

29．D．詞義猜測(cè)題．該下劃線詞所在的句子大意"他說需要全球一致的新方案才能解決這個(gè)危機(jī)"．由此可知，該詞的含義是"解決"，與D項(xiàng)意義相同．
30．A．文章結(jié)構(gòu)題．文章第三段首先提出了問題，然后給讀者解釋了如何解決該問題．因此，正確答案應(yīng)為A項(xiàng)，即"告知和解釋"．

5．American society is not nap（午睡）friendly．In fact，says David Dinges，a sleep specialist at the University of Pennsylvania School of Medicine．"There's even a ban against admitting we need sleep．"Nobody wants to be caught napping or found asleep at work．A proverb says："Some sleep five hours，nature requires seven，laziness nine and wickedness（邪惡） eleven．"
Wrong!The way not to fall asleep at work is to take naps when you need them．"We have to totally change our attitude toward napping，"says Dr William Dement of Stanford University，the godfather of sleep research．
Last year a national commission（委員會(huì)） led by Dement put forward an "American sleep debt" which one member said was as important as the national debt．The commission was concerned about the dangers of sleepiness：people causing industrial accidents of falling asleep while working．This may be why we have a new sleep policy in the White House．According to recent reports，our President is trying to take a half-hour nap every afternoon．
About 60percent of American adults nap when given the opportunity．We seem to have"a mid-afternoon quiet state"，or"a secondary sleep gate"．Sleeping 15minutes to two hours in the early afternoon can reduce stress and make us refreshed．Clearly，we were born to nap．
We Superstars of Napping don't nap just to make up for the lost sleep after a night shift（夜班）．Rather，we take it，whenever，wherever and at whatever time we feel like it．I myself have napped in buses，cars，planes and on boats； on floors and beds； and in libraries，offices and museums．
56．It is commonly accepted in American society that too much sleep isA．
A．unreasonable B．unfit      C．harmful      D．unfriendly
57．The research done by the Dement commission shows thatC．
A．Americans who sleep too much usually get into debts
B．the commission blamed the national debts on people's sleep
C．not enough sleep is no good for Americans and their country
D．napping at work has caused America many industrial and traffic accidents
58．The writer writes this passage in order toD．
A．warn us of the risks of napping
B．show us the dangers of sleeplessness
C．introduce a national commission on sleepiness in America
D．convince the readers of the necessity of napping
59．From the passage，we can learn that"American sleep debt"is the result ofA．
A．the wrong attitude the Americans traditionally hold toward sleep
B．the sleep policy made by the American government
C．the rapid development of American industry
D．the Americans'worry about the dangers of sleepiness
60．The last paragraph tells us that it isD．
A．preferable to have a sound sleep after a night shift
B．good practice not to nap at work
C．essential to make up for lost sleep
D．natural to take a nap whenever we feel the need for it．
