From Mozart to pop music, tons of people enjoy listening to various types of music while they paint, write, or draw. Many believe that music helps improve creativity. But an international study is challenging that viewpoint. 1.
To come to their conclusions, researchers had participants complete verbal (文字的) problems designed to inspire creativity while sitting in a quiet room. 2. They found that background music significantly hurt the participants, ability to complete tasks associated with verbal creativity.
The tasks were simple word games. 3. Then, they were asked to find a single word associated with all three that could be combined to form a common phrase or word. Participants completed the tasks in either a quiet room, or while exposed to three different types of music: music with unfamiliar lines, instrumental music, or music with familiar lines.
Dr. McLatchie and his colleagues conclude that music interferes with (干扰) the verbal working memory of the brain. 4.Also, as far as the library background noises having seemingly no effect, the researchers believe that is the case because library noises create an environment of steady state that doesn't interrupt concentration.
"5.Instead, they demonstrate that music, regardless of the presence of its content, consistently interrupts creative performance in insight problem solving," the study reads.
A. And this in turn holds back creativity.
B. It has nothing to do with the positive reaction.
C. Then again, they were tested while music was played in the background.
D. Psychologists say that their findings indicate music actually blocks creativity.
E. For example, participants were given three words, such as dress, dial, and flower.
F. Before the experiment, the participants didn't study the music they would listen.
G. To conclude, the findings here challenge the popular view that music builds up creativity.
“ 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
The kakapo, a bird that lives in New Zealand, is not designed for survival. Weighing up to 4 kilograms, it is the world's fattest parrot. It mates (交配) only when the rimu tree is in fruit, which happens every few years. It developed gradually in the absence of land-based natural enemies, so instead of flying above the trees it walks like a duck across the dry forest floor. When it moves unsteadily across something that might kill it, it will stand still.
Such unusual characteristics turned it into fast food for human settlers, and for the cats and rats they brought with them. It seemed to have disappeared by the 1970s, until scientists came across two undiscovered populations in the country's south. These survivors were eventually moved to small enemy-free islands, where researchers have spent decades trying to get them to breed (繁殖).
The scientists' patience is finally rewarded. The rimu was in fruit this year, and more than 80 chicks hatched, making this the best breeding season on record. Many have survived into adolescence, increasing the number of adult kakapos by a third, to 200 birds.
Another danger to the kakapo is a lack of genetic diversity. This is one reason why fewer than half of kakapo eggs hatch. By arranging the genome (基因组) of every living bird, scientists can identify closely-related individuals and put them on different islands. Every bird is fitted with something to track its slightest movement. If a female mates with an "unsuitable” male, the process can be stopped.
All these efforts cost almost New Zealand $1.3 million this breeding season. Yet the kakapo's future still looks unsafe. Earlier this year a severe disease tore through the population. And tiny as the number of kakapos is, space is running out on the two islands where most of them live. New enemy-free settlement must soon be found.
1.Which of the following is a danger for the survival of the kakapo?
A.It is the smallest bird in the world. B.It lacks exercise and usually stands still.
C.It adapts slowly in genetic development. D.It can't respond actively when facing danger.
2.In what way may the scientists' patience be rewarded?
A.They hatched 80 kakapos' eggs this year.
B.They tried to make the rimu tree in fruit this year.
C.Two survivors were moved to enemy-free islands.
D.50 chicks hatched have survived into adults this year.
3.Why did the scientists put kakapo in different islands?
A.To stop closely-related kakapos mating. B.To increase the population of kakapo.
C.To stop females mating with males. D.To hatch more kakapos' eggs.
4.According to the author, the efforts to protect the kakapo in New Zealand are _______.
A.successful B.unsafe
C.doubtful D.inadequate
That morning，I dropped our eldest at kindergarten and returned home to let our two younger children play while I worked on my medical report. It was wonderful, but it hit me that my career in hospital wasn't making a difference in anyone's life. I needed something that would stretch my limits and push me to grow. My career enabled me to work from home. I could work from home, and become a foster（领养）mother, providing safety for a child who needed it desperately.
On Monday morning, I picked up the phone and dialed the number I had googled for the nearest Department of Children’ Services. The man on the other end was receptive to my questions and explained the next step of training, involving eight weeks of classes designed to prepare and educate foster parents. We continued through all the classes, the home visits , background checks, and seemingly endless steps.
Five long months after we were approved , the phone Tang. In the middle of the night , I woke my husband and rushed to East Tennessee Children's Hospital- Our placement was waiting for us in the emergency room, sick and lack of nutrition. It didn't take long for us to realize the full depth of her suffering. Six months later, her half-brother came to us by our request. We now had five children under our care.
On August 12, 2016, our family of seven walked into a small courtroom. The children's lawyer and social worker were there. With just a few words, our adoption was finalized. These two amazing children weren't going home, because they were already home. We are their forever family5 and they are our forever children. We may not be able to change the entire world, but we have changed the world entirely for our new children.
