A new study shows that workers should take their full vacation time. There are two reasons. First, when workers take breaks, they are less stressed (有压力的) and happier on the job. Second, workers will actually work harder when they come back. The study says that managers should take their full vacation time too. That’s because if workers see their managers at work all the time, they think they are expected to do the same.

Canadians are usually offered two to three weeks of paid vacation (带薪假期) when they start a job. However, one fourth of Canadian workers don’t take their full vacation time because they are afraid of having too much work to do when they get back. And most of them think they will be better workers in their managers’ eyes by 　　 ▲　　 .

In the USA, the situation is even worse. Over a half of working Americans don’t use all of their vacation time. One of the biggest reasons is that they have too much work. It’s surprising that the United States is the only developed country in the world without a law (法规) to make employers (雇主) offer their workers paid vacation. Some other countries, for example, Germany, Australia and Japan, make employers offer their workers at least four weeks of paid vacation.

1.According to the new study, it’s ______ for both workers and managers to take full vacation time.

A. bad　　 B. easy

C. helpful　　 D. impossible

2.Which of the following can be put in 　　 ▲　　 ?

A. asking for less

B. working at home

C. taking less vacation time

D. listening to them all the time

3.Many working Americans don’t take full vacation time. What’s the main reason?

A. They love their jobs a lot.

B. There’s too much work to do.

C. They want to make more money.

D. Their managers are always working.

4.Alice, a Canadian, has got a job in Germany. The job should include at least ______ paid vacation.

A. four weeks’　　 B. three weeks’

C. two weeks’　　 D. one week’s

5.The above reading is probably ______.

A. a story　　 B. a notice

It might be fun to use your smartphone, but be careful. Too much screen time may be harmful to your health.

First, it is bad for your eyes. A researcher called Sarah Hinkley says the problem comes from the blue light that the screen gives out. Looking at a smartphone for a long time can cause eye strain（劳损）, headaches and dry eyes. So it is a good idea to take a break every 15 minutes when you are working at a computer or using a smartphone.

Second, screen use can do harm to children’s brains. A new study shows that using screens too much can affect（影响） how children’s brains grow. If children use screens for more than one hour a day, they might have lower levels of white matter in their brains. White matter is a key to the development of language and reading skills. So it is wise to cut down the time of children using all kinds of screens.

Third, using screens too much will affect your sleep. According to a study, about 95% of the people between the ages of 13 and 64 use electronics before bed, especially the young people under 20. Doctors say that the light from those electronics at night may make you excited before you go to bed. Then it’s hard for you to get enough sleep. So you’d better turn off smartphones, TVs, and all other screens an hour before your bedtime.

To keep healthy, doctors and researchers strongly advise that you shouldn’t use screens for long hours.

1.The blue light from your screens can cause ________.

A.eyestrain B.headaches C.dry eyes D.all of the above

2.According to the passage, you can’t sleep well because you ________.

A.take a break every 15 minutes B.have lower levels of white matter

C.use screens too much before bed D.are the people from 13 to 64

3.Which of the following is NOT true according to the passage?

A.Using smartphones for long hours does harm to your eyes.

B.A lot of screen time affects children’s brain growth.

C.The light from electronics at night may make you excited.

D.People of all ages mustn’t use electronics.

4.You may read the passage in ________.

A.a science magazine B.a travel diary C.a guide book D.a novel

5.What is the main idea of the passage?

A.The ways to keep healthy. B.The harm of using screens too much.

C.The ways to use screens. D.The advantages of using screens.

Wake up, boys and girls! Put up your hand if you try to repair your tired body by sleeping in(睡懒觉)on weekends. A new study says the habit might not be a good idea for your health.

The ten-day study came out in the magazine Current Biology. Volunteers were divided into three groups. The first group enjoyed nine hours' sleep each night. The second group was allowed to sleep only five hours each night. The third group was given five hours' sleep Monday through Friday.1.But they were put back on the short sleep schedule the next Monday.

Both the second and third groups ate more snacks at night and put on weight. They also saw a decrease (减少) in insulin sensitivity (胰岛素敏感性), a warning sign for diabetes (糖尿病). Researchers have long known a tack (缺乏) of sleep can increase health risks.2.

"Even though people in the third group slept as much as they could on the weekend, it was not enough," said Dr Kenneth Wright, who led the study. "When they went back to the short sleep schedule the next week, their body failed to control blood sugar. 3.

So what should we do if sleeping in over the weekend is not a good choice? 4. Cut out the "sleep stealers" such as watching television shows or spending time on computers or mobile phones. Always remember. Getting enough sleep is as important as having good caring habits or doing exercise regularly.

A.That was partly because their biological clock (生物钟) had been changed.

B.People can repair their tired body by sleeping in on weekends.

C.But it was surprising that the third group had been worse than the second one.

D.Dr Wright gave advice in two words: sleep longer.

E.And then they were allowed to sleep as much as they liked over a weekend.

For some students, getting better grades can seem like an impossible task sometimes. With the challenges（挑战）of school, just paying attention in class or studying hard isn’t always enough. But what if there were other ways for students to improve their grades? For parents and students who have ever wondered if this is possible, now you can rest easy. Research suggests that a person who likes doing activities can improve their grades.

Scientists think that those students who are active are not just exercising their bodies, but also exercising their brains（大脑）. In turn, they can be able to improve their grades at school.

In the most recent study, researchers found that when children played for half an hour each day, they were better at organizing（组织）their schoolwork as well as doing project work and learning traditionally “difficult” subjects, such as maths.

What does this mean for children who aren’t active? Researchers think that if kids don’t get enough activities, they are going to be at a disadvantage when it comes to school performance.

In the research experiment, a group of children skipped with ropes（跳绳）, played basketball and did a number of other games or exercises. Another group of children didn’t do any activities. They took part in testing both before experiment and after the experiment. Testing was mainly for maths and reading skills. Results showed that the children in the activity group did better on the tests than those who had no activity.

All work and no play will not only make Jack a dull（迟钝的）boy, but will also negatively（消极地）affect his grades in school, according to a new study published in the Journal of Pediatrics.

Parents complain（抱怨）children today are actually less active and they always worry about their grades. Dr. Belton, an expert, said,“If you’d like to see your kids do better in school, have them close their books, set down their pencils and go outside to play.”
