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 (病态地) 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.

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(邪恶) 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(委员会) 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.

3.Most people wrongly believe that when people reach old age,their families place them in nursing homes.They (57)are left(leave) in the hands of strangers for the rest of their lives.Their grown children visit them (58)occasionally(occasion),but more often,they do not have any regular visitors.The truth is that the idea is an unfortunate myth-an (59)imaginable(imagine) story.In fact,family members provide the most care(60)that elderly people need.Samuel Prestoon,a sociologist,has studied (61)how the American family is changing.He has reported that by the time the average American couple reach 40 years of age,they have more parents than children.Moreover,because people today live longer after an illness than before,family members must provide long-term care.More (62)psychologists (psychology) have found that all caregivers believe that they are the best people for the job.Social workers interviewed caregivers to find out why they took (63)on the responsibility of caring for (64)an elderly relative.Many caregivers thought they had obligation    9   (help) their relatives,stating that helping others make them feel more useful.Most hoped th at by helping someone,they would deserve care when they became old and dependent.Caring for the elderly and
(64)being taken(take) care of can be a mutually satisfying experience for everyone who might be involved.

5.In China,there are various means of transport for day-to-day living:subways,buses,cars,and even bikes…but taxis rank high on the list.
Taxis are certainly the most convenient means of transport,as(41)itrequires little effort to raise your arm to call a cab.Besides,fares in China are(42)affordable(afford).They start in daytime hours in the capital at RMB 13yuan for (43)thefirst 3kilometers,after which you pay another RMB 2.3yuan per kilometer.This is far less expensive(44)thanthat in European(45)capitals (capital).In London,for example,two kilometers'ride could cost you about RMB 63yuan.
