Sleep, considered a luxury by many, is essential for a person's wellbeing. Researchers have found that insufficient sleep and tiredness increase a person's risk of developing severe medical conditions, such as obesity (being very overweight), high blood sugar levels, and heart disease. Now, a new study has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Gross, the university science professor who led the research, was not trying to find the relationship between sleep and grades when he handed out smart watches to the 100 students in his chemistry class. Instead, the professor hoped the wrist-worm devices, which track a person's physical activity, would show a connection between exercise and academic achievement.
While Gross's data showed no relationship between these two factors, the study found something surprising. As the researchers were analyzing their data, they noticed that there was a straight-line relationship between the average amount of sleep a student got and their results in the course's 11 quizzes, three midterm tests, and the final exam.
Even more interesting, it was not sufficient for students to just head to bed early the night before a test. 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 early hours of the morning performed poorly, even if the total sleep time was the same as a higher-performing student. "When you go to bed matters," Gross says, "If you go to bed at 10, or 12, or 1 at night, and sleep for seven hours, your performance is the same. But if you go to bed after 2, your performance starts to go down even if you get the same seven hours. So, quantity isn't everything."
Perhaps the most interesting was the huge impact that small differences in sleep patterns had on the students' grades. The overall course grades for students averaging six and a half hours of sleep each night were 25% lower than students who averaged just one hour more sleep. Similarly, students who varied their bedtime by even one hour each night had grades that dropped 45% below those with more regular bedtimes.
Who knew getting A's just required some extra ZZZ's?
1.Based on his original objectives, which best describes Professor Gross's research findings?
A.Accidental. B.Complete. C.Convincing. D.Doubtful.
2.Who were the people taking part in the study?
A.Middle school chemistry students. B.Volunteers from different universities.
C.Professor Gross's own students. D.University student athletes.
3.How did Professor Gross's team measure academic performance?
A.Making the students wear a special watch.
B.Using students' university entrance test results.
C.Giving the students regular after class quizzes.
D.Using the students' normal test and quiz grades.
4.Based on the study's findings, who is likely to perform best academically.
A.A person who has a good night's sleep the night before an important test.
B.A person whose normal bedtime varies between 9 p.m. and 12 p.m.
C.A person who sleeps from 11 p.m. to 6 a.m. each day.
D.A person who sleeps for a total of 7 hours each night.

Sleep, considered a luxury by many, is essential for a person’s wellbeing. Researchers have found that insufficient sleep increases a person’s risk of developing severe medical conditions. such as obesity, diabetes, and cardiovascular diseases. Now, a new study by Boston’s Massachusetts Institute of Technology ( MIT) has found that getting sufficient sleep is also the key to improving academic performance.
Jeffrey Grossman, who led the research. was not trying to find the link between sleep and grades when he handed out Fitbits to the 100 students in his introduction to Solid-State Chemistry class. Instead, the professor of Computational Materials Science hoped the popular wrist-worn device which. tracks a person’s activity 24/7, would show a connection between physical exercise and academic achievement.
However, the study, published in the journal “Science Learning” on October 1, 2019, discovered a surprising insight. Then was a straight-line relationship between the average amount of sleep a student got and his/her grade on the 11 quizzes, three midterms, and the final exam administered during the semester.
Even more interesting, it was also not sufficient for students to just head to bed early the night before a test. Instead, it’s the sleep you get during the days when learning is happening that matters most.

For many people shopping is considered to be one of the favorite activities. For most of them it is just buying some new clothes or presents for close people. But there is another way for whom shopping is much more than just enjoyable activity, it is a real addiction that in many cases leads to a financial disaster, as well as it brings troubles to person’s life and family.
So why can shopping be so addictive? What are the possible signs to be aware of? And how is it possible to stop the need of spending?
“Some of the new evidence suggests that some people, maybe 10%-15%, may have a genetic preference to an addictive behavior, coupled with an environment in which the particular behavior is caused, but no one really knows why.” However, it is much better understood as to why “shopaholics” continue with their unhealthy and destructive behaviors. Individuals get pleasure from their addiction the same way as if they were under drugs.
And when is it really possible to determine whether simple shopping has crossed the border and has already turned into addiction?
Shopaholics go out and buy things much more often than other people do. They often buy things they do not need. Many shopping addicts go on shopping binges(放纵) all year long and may be forced to buy certain items, such as shoes, clothing or kitchen items. Some just will buy anything. Many times they will spend over their budget limits and get into deep financial trouble, spending well above their income. While someone else will think many times if they can afford this or that thing, shop addicts will not recognize the boundaries of a budget.
1.We can learn from the 3rd paragraph that .
A. shopping addiction is mainly caused by genetic factors
B. shopping addicts are also addicted to drugs
C. the real cause of shopping addiction is known already
D. shopaholics can’t control their unhealthy and destructive behaviors
2.The last paragraph is mainly about .
A. the destructive behaviors of shopaholics
B. the early signs of shopping addiction
C. the problems of shopaholics
D. the binge of shopaholics
3.What could be most probably discussed in the paragraph to follow the passage?
A. How to treat shopping addiction.
B. What really causes shopping addiction.
C. When shopping addiction takes place.
D. What kind of people can become shopping addicts.
4. It can be inferred from the passage that .
A. shopping addiction can’t cause serious problems
B. shopping addicts only want enjoyable activities through buying
C. it’s not a good idea to let a shopping addict pay by credit cards

Choosing the right university for you is a big decision with many factors to consider. The institution that you choose will not only be the one that ensures your academic goals, but it will also be where you will live, learn, play sports, socialize and work for several years. Therefore, before you start filling out those university application forms, take a step back and consider the many variables that affect the “fit” of a university to your unique personality and educational goals. Take a look at the following factors, and decide which ones mean the most to you.
Consider your educational goals. You will discover that different schools are more recognized or progressive in your chosen field of study than others. For this reason, talk to advisors, professionals in your field, or go to clubs organized by the alumni（校友）. When you check out school ranking for your major, you may find that your first choice is not really a match, while another fits perfectly.
Consider costs. It will be no surprise to you at this point that not all schools cost the same. Some of the more famous schools are so because they are difficult to get into and difficult to pay for. Don’t let this necessarily stop you. Just keep this consideration in mind as you narrow your list of potential schools.
Choosing a university should not be done only on reputation, but also take the academic programs and overall environment into consideration. Be aware that reputations are sometimes out of date or overstated, so first-hand experience is often beneficial.
Once you’ve identified the factors that are most important to you, you’ve taken the first steps towards making a successful choice. Make sure you pick a university that will serve your needs throughout your university career.
1.What does the passage mainly talk about?(No more than 10 words.)
2.How many factors do you need to consider before choosing a university according to the passage? And list at least three of them.(No more than 15 words.)
3.According to the passage, what kind of university is it best for you to choose?(No more than15 words.)
________
4.What does the underlined word variables means in Paragraph One?(Only one word.)
________
5.In your opinion, what other things do we need to take into consideration before choosing a university besides the things mentioned in the passage? (No more than 20 words.)
________

For many of us, a little time with our smartphones or iPads before sleep is the highlight of the night. But would you still think it is relaxing if you knew that it damages or destroys your sleep? Scientists say that's exactly what it does.
In ancient times, when there were no lamps, telephones or smartphones, the sun was the main source of light. When the sun went down, our brains took that as a signal to start producing melatonin(褪黑素), a chemical that helps us sleep.
However, a healthy amount of melatonin can only be produced in complete darkness.Any light in your bedroom—even the one on the alarm clock or the charging indicator on your cellphone—could disturb the process, not to mention something as bright as smartphone and iPad screens. We tend to hold these much closer than a television or laptop, which allows them to shoot far more light straight into our eyes.
“This is particularly worrisome in populations such as young adults and adolescents, who already tend to be night_owls，” said researcher Brittany Wood at Rensselaer Polytechnic Institute.“Lack of sleep among teens is leading to depression, selfharm, low concentration and poor performance at school，” she added.
While all lights are the enemy of sleep, not all colors of light have the same effect. Our eyes are particularly sensitive to blue light, which is common during the day. Most of the light coming from electronic screens is blue light and it fools our brain into thinking it's still daytime. By contrast, orange or red light has less influence on melatonin production, because our brains recognize it as a signal that the day is ending, according to The Telegraph.
Asking yourself to keep your hands off your smartphone before bedtime might seem unreasonable, but you should at least remember to dim the screen or hold it farther away from your eyes. You could also wear a pair of orange sunglasses that take away the harmful blue light.
1.According to the passage, we can know ________.
A．it's a good habit to play with smartphones or iPads late into night
B．scientists suggest we should avoid using smartphones or iPads
C．darkness makes a great impact on the amount of melatonin
D．the sun was the only source of light in ancient times
the sun was the main source of light.”可知D项为错误结论。
2.Which of the following is TRUE according to the passage?
A．The darker it is, the more melatonin will be produced.
B．The lighter it is, the more melatonin will be produced.
C．The more melatonin you have, the worse you'll sleep.
D．The more electrical equipment you have, the more melatonin will be produced.
3.The underlined part in Paragraph 4 refers to those ________.
A．who are young adults or adolescents
B．who don't perform well in school
C．who are addicted to a television or laptop
D．who are short of sleep at night and perform poorly in daily life
4.In the writer's opinion, which is a correct suggestion?
A．You should go to bed when the sun goes down.
B．You should use an orange or red light electronic screen.
C．You should wear a pair of blue sunglasses when sleeping.
D．You should avoid blue light as possible as you can before bedtime.
