8.One in ten teens says they use"study drugs"to improve their performance in school.So-called"study-drugs"refer to prescription medicines(处方药) used to treat ADHD(注意力缺乏症).But most of parents have no understanding of the problem,a new study finds.
In January,2013,researchers from the University of Michigan Mott Children's Hospital did a national survey of more than seven hundred families with teens.They found that only one percent of parents believe their child has taken a study drug.
Yet in a 2012 University of Michigan study,ten percent of second-year high school students and twelve percent of third-year students say they use a study drug.
The misuse of stuffy drugs didn't come to the attention of almost all parents."What we found in this survey is a clear mismatch(不相符),"said Dr.Matthew Davis,one of the researchers."It is a mismatch between what parents believe and what their children were reporting."
"We know teens believe that these drugs can improve their grade,"Davis said."But these prescription medicines are drugs.And teens who use them without a prescription are taking a serious risk."
The new survey showed that fifty-four percent of white parents were"very concerned"about their child taking study drugs,compared with thirty-eight percent of the Hispanic (拉美的) parents and thirty-seven percent of black parents.
However,just twenty-seven percent of parents surveyed talked to their teens about using study drugs.Of these parents,forty-one percent were black,twenty-seven percent were white and seventeen percent were Hispanic.
Students with a prescription for an ADHD drug should be required to keep their medicines in a safe place.Seventy-nine percent of parents think so,the survey shows.This may help preventitfrom being shared or used by other students.
32.According to paragraph 4,Dr.Davis thinks.D

5.Conventional wisdom is a major barrier to innovation(创新)that threatens the survival of companies everywhere.It's based on the assumption that old ideas will always work,so they shouldn't be challenged.While this may be a valid assumption in situations that don't change,it's unlikely to hold true in a changing situation.In today's rapid changing global environment,old methods often don't work,and stubbornly using them can lead to major problems.
    Most people seem to agree with conventional wisdom because it gives one a false sense of security.If everyone else believes it,then it must be true.Individuals who use conventional wisdom are certain that they are right,and being right is good.They want to continue using old ideas rather than take risks with changes that might not work.In 1977,Ken Olsen,co-founder and CEO of Digital Equipment Corporation(DEC),stated"There is no reason for any individual to have a computer in his home."Despite being a dominant leader in the computer industry,DEC no longer exists.
    People seem to forget that since innovation is a change,there can be no innovation without change.Unfortunately,conventional wisdom prevents leaders,followers and companies from changing and therefore innovating.If companies don't innovate,but their competitors do,the future is likely to be problematic.Breaking from conventional wisdom has led to many of the most innovative companies and products in history across many industries,so it has a powerful effect on business success.
    Ted Turner(founder of CNN) knew little,if anything,about the news business,but he knew it was inconvenient to watch news only at the dinner hour,as was common before CNN.Turner's solution was to create a cable channel devoted to news 24 hours a day.The news establishment reflected conventional wisdom at the time,and predicted his idea would fail because no one wanted to watch the news all day.However,it doesn't take a rocket scientist to understand that viewers don't have to watch the news all day for the CNN to work.Viewers just have to watch when they want to get information.Due to conventional thinking,the critics failed to recognize the opportunity that was clear to Ted.They assumed that only what was familiar to them could work in the future.
    Conventional wisdom prevents creativity,flexibility and risk-taking,so unconventional leaders enthusiastically break from it.To survive,boom and maintain competitive advantage,companies must be flexible when reacting to change.
32.DEC has disappeared probably becauseA.
A.the CEO stuck to the conventional ideas
B.the consumers didn't like its products
C.the leaders lacked the sense of security
D.the employees took many risks with changes
33.The founding of CNN is used as an example to proveC.
A.missing opportunities could lead to failure
B.watching news at the dinner hour is convenient
C.changing could contribute to business success
D.conventional wisdom influences business success
34.What does the underlined part probably mean?C
A.Rocket scientists can ensure the CNN works properly.
B.It's easy to know people needn't watch the news all the time.
C.It's necessary to understand when people watch the news.
D.Most of the viewers don't like to watch the news at work.
35.The passage is mainly written to tell us thatD.
A.old methods are changing with time
B.opportunities lead to business success
C.successful companies need wise leaders
D.conventional wisdom limits innovation.

9.A new study has found no evidence that sunscreen,commonly used to reduce the risk of skin cancer,actually increases the risk.
Researchers from the University of Iowa based their findings on a review of 18earlier studies that looked at the association between sunscreen use and melanoma.They said that they found flaws in studies that had reported associations between sunscreen use and higher risk of melanoma.
Most health experts believe that by protecting the skin form the harmful effects of the sun,sunscreen helps prevent skin cancer,which is increasing in incidence faster than any other cancer in the United States.
But question have been raise about sunscreen and whether it may have the opposite effect,perhaps by allowing people to remain exposed to the sun longer without burning.
The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer---people with fair skin and freckles,for example-are more likely to use sunscreen.As a result,it may appear that sunscreen users get cancer more often.
The studies,which generally relied on volunteers to recall their use,were also unable to prove how well the products had been applied,said the new study.
13.The underlined word"flaws"in the 2nd paragraph most probably meansC.
A.evidences        B.facts       C.faults               D.failures
14.We can learn from the passage thatD.
A.sunscreen users get skin cancer more often
B.the volunteers have proved the effects of sunscreen
C.the new study was based on the experiences of volunteers
D.the number of skin caner patients is increasing in America
15.Which of the following can be the best title for this passage?A
A.Sunscreen to Prevent Skin Cancer
B.Sunscreen to Increase Skin Cancer
C.Skin Cancer Caused by Sunscreen
D.Skin Cancer Caused by Freckles.
