Play time is in short supply for young children these days and the lifelong consequences for developing children can be more serious than many people realize.
An article in the most recent issue of the American Journal of Play details not only how much children’s play time has declined, but how this lack of play affects emotional development, leading to the rise of anxiety, depression, and problems of attention and self control. “Since about 1955, children’s free play has been continually declining, at least partly because adults have applied ever-increasing control over children’s activities.” says the author Peter Gray, Ph. D, Professor of Psychology at Boston College.
We can describe the unstructured freely-chosen play as a testing ground for life. It provides critical life experiences without which young children cannot develop into confident and competent adults. So kids need more of it, not less. Because play is how young children learn important social and emotional skills such as sharing, cooperating, communicating, and empathizing. It helps them develop fit bodies, strong minds, and brave hearts, so they can take on new challenges and risky situations.
Gray’s article is meant to serve as a wake-up call regarding the effects of lost play. We must know that lack of childhood free play time is a huge loss that must be paid attention to for the sake of our children and society. But parents who keep a lookout over and disturb their children’s play are a big part of the problem. It is hard to find groups of children outdoors at all, and, if you do find them, they are likely to be wearing school uniforms and following the directions of coaches while their parents dutifully watch and cheer.
Actually, when children are in charge of their own play, it provides a foundation for their future mental health as older children and adults. Play gives children a chance to find and develop a connection to their own self-identified and self-guided interest. It is through play that children first learn to make decisions, solve problems, improve self-control, and follow rules. Play helps children make friends and learn to get along with each other as equals. Most importantly, play is a source of happiness.
When parents realize the major role that free play can take in the development of emotionally healthy children and adults, they may wish to reassess the priorities ruling their children’s lives. The needs for childcare, academic and athletic success and children’s safety is important. But perhaps parents can begin to identify small changes——such as openings in the schedule, backing off from quite so many supervised (有监督的) activities, and possibly slightly less keeping watch on the playground that would start the slow returning to the direction of free, imaginative-directed play.
1.What do we know from the first two paragraphs?
A. The rise of children’s anxiety is more serious than people realize.
B. Lack of play time leads to kids’ unhealthy emotional development.
C. More young children are suffering from depression due to free play.
D. Playing too much leads to problems of kids’ attention and self control.
2.According to Peter Gray, unstructured freely-chosen play _______ .
A. is full of challenges and risky situations
B. should be balanced with adult-directed activities
C. does harm to children’s confidence and competence
D. has good effect on children’s social and emotional skills
3.The article is intended for ____________.
A. parents B. teachers
C. coaches D. children
4.Which of the following would be the best title for the text?
A. Do Children Need More Self-guided Play?
B. Are Children Interested in Guided Play?

“ New and improved. ” These words are put in so many marketing campaigns that we tend to accept them as linked. But many new drugs aren't an improvement over the best existing drug for a given condition, and the fast drug-approval processes in recent years have added to the uncertainty about their advantages.
A recent report in the British Medical Journal, "New Drugs: Where Did We Go Wrong and What Can We Do Better?, analysed the issue, The authors looked at 216 drugs approved between 2011 and 2017 ; 152 were newly developed, and 64 were existing medicine approved for new uses. Only 25% offered a major advantage over the established treatment, and fully 58% had no confirmed added benefit to reduce symptoms or improve health-related quality of life.
"This doesn’t mean there's no added benefit," lead author Wieseler said. “It just means we have no positive proof. Either we have no studies or have studies not good enough. ” Wieseler and her co-authors work for a German institute which evaluates new treatments and advises on whether the country's health care system should pay a premium ( 占)for them. Such organizations , known as health technology assessment ( HTA) agencies, work a little differently in the US, says Sean Tunis,a researcher in Baltimore: “ If payers think a new drug isn't better than an existing drug,these agencies will require .that hospitals try the cheaper drug first. ”
Germany's HTA demands trials to prove that a new treatment beats the existing standard. This isn't always practical For one thing, such studies can be expensive and time-consuming, with no guarantee of success. Secondly, it can discourage companies from attempting to develop new alternatives. This is already happening. Drug developers are increasingly focused on areas where there are no good treatments to compete with, such as rare diseases.
This lack of meaningful data to guide patients is a major point of Wieseler's paper- With accelerated approval, there are more products approved, with a greater amount of uncertainty about risks and benefits. But there are other solutions besides drug trials. One idea is to require postmarket studies to track the effectiveness of newly approved drugs—a step too often neglected.
1.What message does the recent report convey?
A.Many new drugs have no improved advantages.
B.The approval processes for new drugs are too fast.
C.Improved drugs have advantages over old ones.
D.Before 2017 no improvement was made to drugs.
2.What will US HTA agencies do when no advantage is found in new drugs?
A.Remove government premium on them.
B.Get hospitals to use the cheaper drugs.
C.Arrange financial support for the patients.
D.Put new drugs on further trials and studies.
3.What's the disadvantage of Germany's HTA trial demands?
A.Making drug companies think of illegal ways to cut cost.
B.Pushing companies to try alternatives for existing drugs.
C.Getting patients to depend on the government for support.
D.Holding companies back from improving existing drugs.
4.What is the best title for the text?
A.The Advantage of Existing Drugs
B.Misunderstanding of New and Old Drugs
C.A Dilemma with New Drug Alternatives
D.Peopled Preference for New or Old Drugs

高三英语单项填空简单题查看答案及解析
Back in old times, people had little knowledge about the universe and nature. Things we now consider to be common sense were mysteries to our ancestors.
Over the years, major breakthroughs have been made in science and many phenomena have been explained. But still, there are always questions we can't yet answer, and The Guardian has listed some of them.
1. What makes us human?
Just looking at your DNA won't tell you - human DNA is 99 percent identical to that of the chimpanzee and, believe it or not, 50 percent identical to a banana's! A lot of the things we once thought were unique about us - language and tool use, recognizing ourselves in the mirror and so on – have since been seen in other animals. Perhaps it's our culture that makes the difference or maybe our ability to use fire. It's also possible that our capacity (能力) for co-operation and our trading skills are what make us unique.
2. Why do we dream?
Given the fact that we spend around a third of our lives sleeping, shouldn't we know everything about it? Unfortunately, scientists are still searching for a complete explanation of what happens when we sleep and why we dream.
Austrian psychologist Sigmund Freud believed dreams were the expressions of wishes that we can't fulfill in our real lives. Others have wondered whether dreams are just random "noise" coming from a sleeping brain.
3. Could we someday live forever?
Apart from accidents, most people die because of diseases that can be treated and aging. And since many diseases, such as diabetes(糖尿病) and cancer, are diseases of aging, treating aging itself could be the key to extending our lives.
Our knowledge of what causes us to age - and what allows some animals to live longer than others - is expanding rapidly. And though we haven't quite worked out all the details, we've worked out some pieces of the puzzles such as DNA damage and metabolism (新陈代谢), which are all leading to the invention of drugs that can slow down the aging process.
If we're lucky enough to lengthen our lives, we might even get to see the day when all of these questions are answered.
1.The main point of the passage is ______.
A. to inform people of the knowledge about the universe and nature
B. to introduce major breakthroughs that have been made in science
C. to present some questions we can't yet answer
D. to explain what were once mysteries to our ancestors
2.Chimpanzees and bananas are mentioned as examples to prove that ______.
A. human beings are actually not different from other animals
B. animals have completely different DNA from that of plants
C. both animals and plants share the same amount of DNA
D. DNA alone is not good enough to make humans different
3.The underlined word "identical" is closest in meaning to ______.
A. mysterious B. unique C. advanced D. same
4.Which of the following statements is TRUE according to the passage?
A. What were mysteries to our ancestors are considered to be common sense now.
B. Now we know much more about dreams than our ancestors did in the past.
C. With the invention of new drugs people can possibly live even longer.
D. If all the diseases can be treated people can theoretically live forever.
