Take a look inside a high school classroom. You will most likely find a teacher at the front of the class and students sitting at their desks. Yet, look closer, and you might notice a familiar scene: many of these students are not paying attention. Instead, they are dozing off(打盹)or even completely asleep.

Today, the majority of high school students are not getting enough sleep. This lack(缺乏)of sleep is a serious problem, especially as students are doing more than ever with their time. They come to school early, spend hours listening to teachers and taking tests, then run off to practices and meetings, and come home to be faced with even more work. And the homework load these days is not light; teachers give hours worth of homework each night.

Most kids need at least nine hours of sleep per night in order to function properly. Yet the period of this nine hours shifts as a child gets older. After puberty(青春期), the body's internal clock changes so that it is difficult for teens to fall asleep before 11 p. m. So even if a student falls asleep at eleven, they would need to sleep until at least 8 a. m. to get a full night's sleep. Considering the time at which most high schools in this country begin, those nine hours are clearly being shortened. Few high schools start after 8 a. m.

However, there are schools that have paid attention to this research and pushed backward the start of their school day. In schools where the start time is after 8:30 in the morning, the teachers believe that there has been a real change in their students. They note that the students miss class less, pay more attention in class, perform better in class, and report lower levels of depression(沮丧), The researchers of these studies say that the results are quite important and that more schools should consider pushing backward their start time of their school day.

1. Which of the following would the author agree with?
A.High school students must go to bed before 10 p. m.
B.High schools should begin their school day at a later time
C.Most schools should push forward the start of their school day.
D.Kids should shorten their sleep time gradually as they grow older.
2. The second paragraph mainly discusses ________.
A.why high school students should get more sleep
B.what's life like for high school students at present
C.why high school students feel sleepy in the classroom
D.how to lighten high school students' homework load
3. The underlined word "shifts" probably means "________”.
A.arrivesB.reducesC.increasesD.changes

【推荐2】In China, many people are leaving the countryside to find jobs in the cities, because the countryside is much poorer than the city, and often there isn’t much work there. Services such as hospital and transport are usually much better in the city than in the countryside. They hope that their lives will improve when they move to the city.
But in the big cities of Europe like London or Paris, people are moving out of the city. These rich families want to live a quieter life. They are tired of the noise and the dirt of the city, and they are tired of the crowded streets, crowded trains and buses. They don’t want to live in the cities any more. They want a house with a garden in the countryside, and breathe the fresh air there.
So they move out of the cities. Some don’t go very far, just a little way out of the city, to the towns near the cities; other people move to the real countryside with sheep, cows and green fields. There, they start new lives and try to make new friends.
Not all those who move from the city to the countryside are happy. After two or three years, many people who have done this feel that it was a big mistake. They don’t make so much money and there isn’t much work to do. People in the countryside are very different and aren’t always very friendly.
As a result, quite a lot of people who have moved to the countryside move back to the city. “_______________________________” they say.

【推荐3】A study from a team of South Korean researchers suggests that eating alone often may lead to poor eating habits and poor food choices. And the study found that people who ate alone more than twice a week had a greater risk of developing high blood pressure and heart disease.

For children, eating with their families is not only about stopping bad outcomes(结果)— it is also about developing good ones.

In 2014, the Organization for Economic Cooperation and Development(OECD)looked at data from nearly three-quarters of the world’s countries. Among its findings was the fact that students who shared a main meal with their families were less likely(有可能的)to drop out of school. Children who eat a main meal with their families are also less likely to abuse drugs and alcohol(吸毒酗酒).

In the report, titled “The Importance of Family Dinners(VIII)” researchers say that “teens who have frequent(经常的)family dinners are more likely to say their parents know a lot about what’s going on in their lives”. They also say that when teens think they are closer to their parents, they are less likely to use drugs and alcohol.

Another study from the University of Montreal found that children who ate with their families experience long-term health benefits(好处). These children were in better health and drank fewer sugary soft drinks. These children also seemed to have better social skills and they were friendlier.
