Sleep is essential for a person’s wellbeing. ...

Sleep is essential for a person’s wellbeing. Researchers have found that sleep loss increases a person’s risk of developing serious medical conditions. Now, a new study has found that getting enough sleep is also the key to improving academic performance.

Jeffrey Grossman, who led the research, was not trying to find the correlation (相关性) between sleep and grades when he handed out Fitbits to the students in his class. Instead, the professor hoped the popular wrist-worn electronic device (装置), which tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.

As part of the research, a quarter of the participants chose a fitness class specially created for the study. After the school term ended, the researchers carefully analysed the data. Much to Grossman’s surprise, they found no measurable difference in test performance between the group that had been physically active and the group that had not.

However, the study presented a surprising viewpoint in the journal Science of Learning. Going through the large amount of data, Grossman noticed an interesting trend (走向) from the participants sleep patterns. There was a straight-line relationship between the average amount of sleep and his/her grade on the exams.

Besides, it was not enough for students to just head to bed early the night before a test. Grossman says: “We’ve heard the phrase ‘Get a good night’s sleep, you’ve got a big day tomorrow.’ It turns out this does not relate at all to test performance. Instead, it’s the sleep you get during the days when learning is happening that matters most.”

The time students went to bed each night was similarly important. Those who went to bed in the early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student.

The research does not prove that sleep is the only component that helps improve academic performance. However, Grossman says the results are a strong indication that sleep really matters. Who knew getting A’s just required some extra ZZZ’s?

1.What’s Grossman’s original purpose by using Fitbits in the research?

A.To improve students sleep patterns.

B.To regulate students’ daily behavior.

C.To monitor students’ physical condition.

D.To find effects of physical exercise on grades.

2.What did Grossman think of the research result?

A.It was unexpected. B.It was changeable

C.It was unreliable. D.It was fruitless.

3.What plays a more important part in test performance?

A.Sleep in the learning stage. B.Average amount of sleep during tests.

C.Sleep quality the night before the test. D.A regular bedtime.

4.What is the best title for the text?

A.Be Physically Active and Sleep More

B.Enough Sleep Benefits Our Wellbeing

C.Catch ZZZ’s for Good Test Performance

D.The More Exercise, the Better Schoolwork

A polished resume is essential for a successful school or job application. A clear structure and well-organized content can be the difference between success and failure.

Structuring your resume

(1) Create a header with your name and contact information. There are also down loadable templates(模板) available online. If none of them appeals to you, however, you can always use your own design.

(2) Use a chronological(时间顺序排列的)resume. In a chronological resume, you list your work and education experiences, starting with your most recent experience.

(3) Include your relevant education, awards or training. Typically, your highest academic qualification is the only one you need to include on your resume.

If you had a cumulative(累积的)GPA of 3.5 or higher, feel free to include it. Otherwise, it would be best to leave it out. If you re listing more than one degree, include your GPA on both of them, if possible.

(4) List work experience, including relevant volunteer work and internships. Use specific job titles and short explanations that tell potential employers exactly what you did, what skills you gained and how they could be useful in a new job.

(5) Try a functional resume, if you lack direct work experience. With a functional resume you can highlight your specific skills and resources without having to list previous jobs. A functional resume emphasizes what you can do rather than what you've done.

For a long time hikers in Japan have considered a bear bell essential. Its tinny ring is said to scare off huge creatures. Nowadays, however, bear bells are increasingly useful on the way to the shops as well as in the wild. “The number of animals - whether bears, boars or monkeys --is expanding, and they are going into villages and towns”, says Hiroto Enari of　 Yamagata University.

Japan is home to many species of wild animals, including both black and brown bears. Estimates of their numbers are unstable, but since the 2000s the number of bear sightings has been rising. There were close to 1 3 , 000 in 2018 alone. The reappearance has its roots in the truth : the shrinking of Japan’s population is especially sharp in rural areas, where it is more serious by ongoing urbanization. The reducing quantity of people, in turn, has emboldened (使大胆)animals. Bears are less limited about entering villages in broad daylight if there are few folks around, Mr Enari says. Indeed, the biggest jumps in sightings have been where the population is falling fastest.

Hunting is declining in Japan, too. Government data suggest that the average hunter is now 68 years old. The country’s many forests and mountains provide an expansive habitat for wild animals. Indeed, the true wilderness is growing as foresters and farmers die off. Bears become particularly bold in years when acorns (橡实)are scarce, sneaking into orchards (果园)to steal fruits.

While some welcome their reappearance? others suffer from it. Every year bears injure scores of people, and kill a handful. Deer cause damage to farmland and speed up erosion by, for example, eating up grass. Simple solutions, such as changing the layout around villages or putting up fences, are rarely used. Instead, many bears are captured or killed. In 2013 the government decided to halve the number of certain types of deer, boars and monkeys by 2023. Japan is struggling to adapt to the changing power balance between animals and people”, says Mr Enari.

1.In Japan, what were the bear bells first used for?

A.Warning people of bears’　 appearance.

B.Safeguarding the shops and villages.

C.Driving away various wild animals.

D.Scaring off bears for the hikers.

2.What can we learn from paragraph 2?

A.It is hard to see a brown bear in Japan.

B.The number of bear sightings has declined since 2000.

C.Japan’s reducing population is a main cause for bears’ reappearance.

D.Bears appear most frequently where the population increases fastest.

3.What is the other cause for wild animals’ reappearance?

A.The increase of forests. B.The decline of hunting.

C.The reduction of their habitats. D.The death of foresters and farmers.

4.What is the last paragraph mainly about?

A.The problem wild animals bring about and related measures to handle it.

B.Japanese people’s attitude to the reappearance of wild animals.

C.Methods for killing wild animals and the government’s attitude to them.

D.The wild animals’ future Japanese experts expect.

It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations.

Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few possibilities of a commercial return, and Lee’s is one of them.

The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities.

Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary (多学科的) team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”

1.By “a one-way street” (Line 1, Para. 1), the author means ________.

A. university researchers know little about the commercial world

B. there is little exchange between industry and academia

C. few industrial scientists would quit to work in a university

D. few university professors are willing to do industrial research

2.The word “deterrent” (Line 3, Para. 1) most probably refers to something that ________.

A. keeps someone from taking action

B. helps to move the traffic

C. attracts people’s attention

D. brings someone a financial burden

3.What was Helen Lee’s major consideration when she changed her job in the middle of her career?

A. Flexible work hours.

B. Her research interests.

C. Her preference for the lifestyle on campus.

D. Prospects of academic accomplishments.

4.Guy Grant chose to work as a researcher at Cambridge in order to ________.

A．do financially more rewarding work

B．raise his status in the academic world

C．enrich his experience in medical research

D．take advantage of better intellectual opportunities

5.What contribution can industrial scientists make when they come to teach in a university?

A．Increase its graduates’ competitiveness in the job market

B．Develop its students’ potential in research.

C．Help it to obtain financial support from industry.

D．Adapt its research to practical applications.
