A new study found the greater the improvement in people’s handwashing habits at airports, the more noticeable the effect on slowing the infectious (传染的) diseases, including the flu. The findings were published in late December, 2019, just before the recent coronavirus (冠状病毒) outbreak, but the study' s authors say that its results would apply to any such disease and are relevant to the present outbreak.
People can be surprisingly casual about washing their hands, even in crowded locations like airports where people from many different locations are touching surfaces such as chair armrests, check-in entrances, security checkpoint trays, and restroom doorknobs and taps. On average, only about 20 percent of people at airports have clean hands. The others are potentially polluting everything they touch with whatever infections they may be carrying.
Improving handwashing at all of the world's airports to be three times that rate, so that 60 percent of travelers have clean hands at any given time, would have the greatest effect, potentially slowing global disease spread by almost 70 percent, the researchers found. Adopting such measures at so many airports and reaching such a high level of obedience may be impractical, but the new study suggests that it could potentially be accomplished through education, posters, public announcements, and perhaps improving access to handwashing facilities. It could slow the global rate of the spread of a disease by about 24 percent, they found.
The findings are consistent with recommendations made by both the U. S. Centers for Disease Control and the World Health Organization. Both have indicated that hand hygiene (卫生) is the most efficient and cost-effective way to control disease spread. While both organizations say that other measures can also play a useful role in limiting disease spread, such as use of surgical face masks, airport closures, and travel limitations, hand hygiene is still the first line of defense-and an easy one for individuals to implement.
1.What is most people’s attitude to handwashing?
A.Favorable. B.Careless.
C.Doubtful. D.Cautious.
2.What did the study suggest on increasing handwashing rate at airports?
A.Establishing higher hygiene standards.
B.Making handwashing fun and enjoyable.
C.Passing special laws to require handwashing.
D.Raising people's awareness of handwashing.
3.Why does the author mention the World Health Organization?
A.To introduce other measures.
B.To stress the importance of it.
C.To tell who carried out the study.
D.To make the study results more convincing.
4.What is the text mainly about?
A.People have many good habits at airports.
B.Handwashing reduces infectious diseases.
C.New coronavirus is breaking out.
D.There is great improvement in handwashing.

A new study has found that cats can connect with people in the same way as dogs and children.The research, published in Current Biology, suggests the social abilities of cats to form human attachments has been greatly underestimated.The study notes that more cats live with humans than dogs do worldwide.But historically, more scientific research has centered on the social relationships between people and dogs.
The researchers designed experiments similar to methods used to measure human attachment behaviors.For example, other studies have observed how babies react to being reunited with caregivers after being separated for short periods.
About 70 cats were studied.The hehavior of the animals was observed by experts who divided them into two groups.64 percent were judged to be “securely attached”to caregivers, while 36 percent were found to be “insecurely attached.”The cats with secure attachments showed several signs of “reduced stress”levels, the study found.These cats were found to be more comfortable and effectively balanced their attention between the person and their surroundings.However, the cats with an insecure attachment showed clear signs of stress.These included shaking of the tail, repeated licking or staying completely away from the caregiver.
She added that the results showed that the level of secure and insecure attachments in cats is very close to those measured in human babies.In humans, research has found that 65 percent of babies are also securely attached to their caregivers.The researchers also were interested in finding out if socialization training would change the results.
But after a six-week training program for the cats, there were no major differences. “Once an attachment style has been established between the cat and its caregiver, it appears to remain relatively stable overtime, even after a training and socialization intervention(干预), ”Vitale said.
1.What does the study mentioned in this passage show?
A.Cats’social ability is little thought of.
B.Dogs have more sociable personalities than cats.
C.Historically, dog is much smarter than cats.
D.Cats have bad social relationships with dogs.
2.What will happen if the cats feel unsafe?
A.They tend to attack their caregivers.
B.They are going to shake their tails.
C.They will stay close to their caretakers.
D.They are likely to balance their attention.
3.What can we infer from the last two paragraphs?
A.Attachment level in babies is higher than in cats.
B.Training program plays an important role in the results.
C.Researchers feel insecure when experimenting with cats.
D.It’s hard to make changes to attachment styles between cats and caregivers.

In a six-week study, experts found people who played online games designed to improve their cognitive(认知的) skills didn't get any smarter.
More than 8,600 people aged 18 to 60 were asked to play online brain games designed by the researchers to improve their memory, reasoning and other skills for at least 10 minutes a day, three times a week. They were compared to more than 2,700 people who didn't play any brain games, but spent a similar amount of time surfing the Internet and answering general knowledge questions. All participants were given a sort of I.Q test before and after the experiment.
Researchers said the people who did the brain training didn't do any better on the test after six weeks than people who had simply been on the Internet. On some sections of the test, the people who surfed the Net scored higher than those playing the games.
"If you're (playing these games) because they're fun, that's absolutely fine," said Adrian Owen, the study's lead author. "But if you're expecting (these games) to improve your I.Q., our data suggests this isn't the case," he said during a press briefing on Tuesday.
One maker of brain games said the company's games have been proven to boost brain power.
"Their conclusion would be like saying, 'I cannot run a mile in under 4 minutes and therefore it is impossible to do so," Aldrich said in a statement.
"There is precious little evidence to suggest the skills used in these games transfer to the real world," said Art Kramer, who was not linked to the study and has no ties to any companies that make brain training games.
Instead of playing brain games, Kramer said people would be better off getting some exercise. He said physical activity can spark(激发) new connections between nerves and produce new brain cells. "Fitness changes the building blocks of the brain's structure," he said.
1.. It can be inferred that the online brain games mentioned in the text are_____________.
A. costly B. unreliable C. illegal D. effective
2.. Which of the following statements is true about the experiment in the second paragraph?
A. The experiment lasted for a week.
B. Age didn’t affect the result of the research.
C. Every person played online brain games three times a day.
D. People who didn’t play online brain games did better in I.Q test
3.. What can we learn from the text?
A. Playing games which are fun can improve your I.Q.
B. There is a lot of evidence to suggest skills can transfer to the real world.
C. Do physical activity can boost your brain power.
D. Playing online games can spark new brain cells
4.The underlined sentence suggests that ___________.
A. The research was not linked to the study
B. Those playing the games can score higher in the test
C. playing the games can spark new connections between nerves
D. This isn’t the case that these games can improve your I.Q.

A new study has found that it may be possible to train people to be more intelligent，increasing the brainpower they had at birth.
Until now，it has been widely assumed that the kind of mental ability that allows us to solve new problems without having any relevant previous experience—what psychologists call fluid intelligence—is innate and cannot be taught（though people can raise their grades on tests of it by practicing）.
But in the new study，researchers describe a method for improving this skill，along with experiments to prove it works.
The key, researchers found, was carefully structured training in working memory—the kind that allows memorization of a telephone number just long enough to dial it. This type of memory is closely related to fluid intelligence，so the researchers reasoned that improving it might lead to improvements in fluid intelligence.
First they measured fluid intelligence of volunteers using standard tests. Then they trained each in a complicated memory task—the child’s card game，in which they had to recall a card they saw and heard. During the course, they needed to ignore irrelevant items，monitor ongoing performance，manage two tasks at the same time and connect related items to one another in space and time.
The four groups experienced a half-hour of training daily for 8，12，17 and 19 days，respectively. To make sure they were not just improving their test-taking skills，the researchers compared them with control groups that took the tests without the training.
The results, published Monday in The Proceedings of the National Academy of Sciences，were striking. Improvement in the trained groups was a lot greater. Moreover，the longer they trained, the higher their scores were. All performers，from the weakest to the strongest，showed significant improvement.
“Our results show you can increase your intelligence with proper training.”said Dr Jaeggi, a co-author of the paper.“No one knows how long the gains will last after training stops，”he added，“and the experiment’s design did not allow the researchers to determine whether more training would continue to produce further gains.”
67．The researchers thought the key to improving the intelligence was ______________.
A．memorizing telephone numbers
B．improving working memory
C．training in concentration
D．recalling a card
68．The following aspects of the training help increase intelligence EXCEPT___________.
A．ignoring irrelevant items
B．monitoring ongoing performance
C．managing two tasks at the same time
D．using previous experience
69．When the experiment was conducted，the researchers______________.
A．trained the four groups for the same period of time
B．only made comparisons between the four groups
C．compared the four groups with control groups
D．trained the four groups together
70．By writing the article，the writer intends to ______________.
A．inform the readers of a new study
B．call on people to be trained to increase intelligence
C．prove one’s born brainpower can be improved
D．tell people the improved intelligence will last forever

Many people don't realize the importance of music education in the schools today. A new study showed, however, music education is extremely important.
In college, music education is one of the largest programs. Teachers have to learn general education materials and techniques. They must learn to play every instrument; they must learn music history and music theory; they must learn instrument repair and teaching methods; they must learn conducting and so much more. At the same time, much of our culture and tradition is absorbed in music.
Music plays a very important role in our education.
Music helps with math and science. Students learn to count, and how to multiply and divide. Students also use science to help them discover what sounds good together and what doesn’t. Students also need science to understand something called the “overtone series", which is about how music is produced by vibration（颤动）and why.
Students learn a lot about languages through music．Many songs are written in other languages, including ancient ones. Students must learn to translate these works to understand what they are singing about. A song is likely to be a famous short work set to music; so students are exposed to that very often while singing.
Students learn a huge amount of cooperation （协作）of body parts through music, so parts of the body can work better together. Students must use motor（肌肉运动的）skills in order to play an instrument. Singers and wind（管乐器）players must learn breath control and be in good shape to play.
Students learn about art. Some famous pieces were written about important pieces of art, and students learn about the artists and styles as they're playing the music.
Music education also brings higher thinking to our children. It allows them to think about complex patterns. Students have to be aware of what every other musician does at every time. In that way, it develops cooperation, as well. They tend to develop more ability for learning.
As one can see, music is very important to education.
1. What can we infer about learning music in college?
A. It is an easy task without much effort.
B. It attracts more and more people to learn.
C. It is such a challenging job to finish
D. It has no value to our future life.
2. Music benefits us a lot in many ways except for_______.
A. making us a scientist later.
B. improving language ability
C. bettering cooperation of body parts.
D. making us think more about how to learn well
3. The underlined word “that” in Para. 5 refers to “_________”
A. the music B. the workC. the culture D. the language
4. What can we know from the passage?
A. A good achievement of science is vital to music learning.
B. Learning music to a higher level on one’s own is impossible
C. People have long known the importance of music to our growth.
D. Music has benefits to the all—around development of human beings.

A new study explores the custom of tipping in the United States. Many Americans give tips to people who perform a job for them, especially workers in the service industry. They pay a little extra to people cutting their hair, driving them across town or serving them a meal at a restaurant.
The researchers found that men give bigger tips to restaurant workers than women. And people who live in the northern US are more generous with tips than those living in the South. People who earn $ 50, 000 or more a year give bigger tips than those who earn less than $50, 000. There is one likely reason: the wealthier Americans have more money to spend.
Michael Lynn is a professor of consumer behavior and marketing at the Cornell University School of Hotel Administration in New York. In other words, he knows a lot about the issue of tipping. In earlier surveys, Lynn said he found mixed results on the generosity of men and women when it comes to tipping. In some studies, men gave bigger tips than women. In others, women gave more money.
Lynn’s own research in American restaurants found that men give bigger tips when the restaurant server is a woman and women give more when the server is a man. Tips are very important to service employees. People who work at restaurants often get most of their earnings from tips.
Nationwide, Americans generally tip between 15 to 20 percent at restaurants and leave from $2 to S 10 a day for the people who clean their hotel rooms. Tips of 15 percent of the reading on the meter (计价器) are also common for people who drive taxis.
But here is something to keep in mind. If you are able to give the person serving you a tip or a bigger one than what is expected, your generosity will be welcome. Many service workers do not make much money, and even an extra dollar or two can make a difference in their lives.
1.What is paragraph I mainly about?
A. A study in a restaurant. B. A job offering a lot of tips.
C. The service industry in the US. D. The custom of tipping in the US.
2.What is Lynn’s finding in American restaurants?
A. People give more tips to the opposite sex server.
B. People are always more generous to service employers.
C. Men give the same tips to the women restaurant servers as women.
D. Men always give more tips to the men restaurant servers than women.
3.How much tips do Americans generally pay if the reading on the taximeter is $100?
A. $2. B. $10.
C. $15. D. $20.
4.What is the authors attitude towards tipping?
A. Doubtful. B. Critical.
C. Uncaring. D. Supportive.
