When your alarm clock rings and you drag yourself out of bed, you probably wonder： Why on earth does school have to start so early?

Fortunately, there is a new law to support—or better still, science.

A law in California, passed on Oct 13, requires that public middle schools begin classes no earlier than 8：00 am and that high schools start no earlier than 8：30 am. The law will go into effect by July 1, 2022.

Starting school at 8：00 or 8：30 in the morning may not sound like too big of a change, but it could mean one more hour of sleep for students who used to start school at 7:30 or even earlier.

"The effect of that one hour is something they will be feeling as 40-year-old adults," Sumit Bhargava, a sleep expert at Stanford University, told The New York Times. He said that not having enough sleep can affect students' mental health and increase the risk of being overweight and diabetes （糖尿病）.

In the short run, students' school performances should improve almost immediately. Kyla Wahlstrom, a researcher at the University of Minnesota's College of Education, found that students who have enough sleep are alert in class and get much more satisfying grades.

Some might say that asking students to go to bed earlier could have been a much easier solution than changing the school timetable across an entire state. But according to the American Academy of Sleep Medicine, teenagers go through biological changes when they enter puberty （青春期）,which makes it difficult for them to fall asleep before 11：00 pm. So when school starts at 8：00 or earlier, they can hardly get the ideal 8.5-9.5 hours of sleep that experts suggest they need to do their best in the daytime.

This is why when the new law came out, its author, Anthony Portantino, said, "Generations of children will come to appreciate this historic day and our governor for taking action."

1.Which of the following is TRUE about the law?

A.The law has not been put into practice.

B.The law requires schools to start later than 8：30am.

C.The law will be passed by July 1, 2022.

D.The law is made by a university in California.

2.What does the underlined word alert in Paragraph 6 probably mean?

A.Friendly. B.Sharp.

C.Calm. D.Honest.

3.For a better academic performance in the daytime, how long do teenagers probably need to sleep?

A.About 8 hours. B.About 9 hours.

C.At least 10 hours. D.At most 8. 5 hours.

4.What's the main idea of the text?

A.Lack of sleep could lead to health problems.

B.The amount of sleep people need changes with age.

C.A new law lets students sleep longer.

D.Sleeping problems are leading problems for teenagers.

If you ever have the desire to break out into song—in the shower, in the car, maybe at your neighbor's karaoke night—you should embrace it whole-heartedly. This ancient art not only makes you feel good, it can also improve your well-being, reduce your feelings of pain, and even extend your life.

Using your voice to sing, rather than simply carryout a conversation, offers unique benefits because singing affects our bodies. Also, studies link singing with a lower heart rate，decreased blood pressure and reduced stress according to Patricia Preston-Roberts, a music therapist. She uses song to help patients who suffer from a variety of problems.

Singing, particularly in a group, seems to benefit the elderly particularly well. As part of a three-year study examining how singing affects the health of those fifty-five and older, a Senior Singers Chorus was formed by the Levine School of Music in Washington, D. C. The seniors involved in the chorus, as well as seniors in two separate arts groups about writing and painting, showed significant health improvements compared to those in the control groups (控制组).Obviously, the arts groups reported thirty fewer doctors' visits, fewer eyesight problems, less depression, and less need for medication.

Even lead researcher Dr. Gene D. Cohen, director of the Center on Aging at George Washington University, was surprised at how big an effect the seniors' arts participation had on their health. Cohen said, “The average age of all the subjects was eighty. This is higher than life expectancy. So, if an effect were to be achieved, one would ordinarily expect to see less decline (下降) compared to the control group. The fact that there was so much improvement in many areas was the surprising factor." The seniors also noticed health improvements and they reported feeling better both in daily life and while singing.

The part of the brain that works with speech is different from the part that processes music. “People seem to enjoy doing something jointly with other people. There are a lot of facts that being socially involved is good for people with dementia (老年痴呆).”Ballard said.

The arts are showing up as a treatment tool in hospitals across the country. If you are thinking of volunteering, singing at a hospital may be a good choice—not only for the patients, but also for yourself.

1.In the first paragraph, the author ________.

A. expresses a desire for singing

B. offers some advice on singing

C. puts forward his point of view

D. states the importance of health

2.Why was Cohen surprised at the results of the study?

A. The study was not expensive as expected.

B. Arts acted as a treatment tool in hospitals.

C. People's health in the arts group improved greatly.

D. The seniors themselves noticed health improvements.

3.What is the author's attitude towards arts?

A. Doubtful.　　 B. Positive.

C. Negative.　　 D. Worried.

4.What would be the best title for the passage?

A. How to Avoid Getting Dementia

B. How Seniors Live a Healthy Life

C. How to Keep Our Brains Healthy

D. How Singing Improves Your Health

The key to happiness is how quickly you can get back your focus on what`s important.

——Anonymous

Sixteen years ago I learned this lesson in the back of a New York City taxi cab. Here`s what happened. I hopped in a taxi，and we took off for Grand Central Station. We were driving in the right lane when，all of a sudden，a black car jumped out of a parking space right in front of us. My taxi driver slammed on his brakes，skidded，and missed the other car`s back end by just inches!

The driver of the other car，who almost caused a big accident，started yelling bad words at us. My taxi driver just smiled and waved at the guy. And I mean，he was friendly.  So，I said，"Why did you just do that？This guy almost ruined your car and sent us to the hospital！"And this is when my taxi driver told me what I now call "The Law of the Garbage Truck. "

Many people are like garbage （rubbish）trucks. They run around full of garbage，full of frustration， full of anger，and full of disappointment. As their garbage piles up，they need a place to dump it. And if you let them，they`ll dump it on you. When someone wants to dump on you，don`t take it personally. You just smile，wave，wish them well，and move on. You`ll be happy with what you did.

I started thinking，how often do I led Garbage Trucks run right over me？And how often do I　take their garbage and spread it to other people at work，at home，or on the streets？It was that day I said，"I`m not going to do anymore. "

Successful people do not let Garbage Trucks take over their day. What about you？If you let more garbage trucks pass you by，you`ll be happier. Life`s too short to wake up in the morning with regrets. So，Love the people who treat you right. Forget about the ones who don`t.

1.What happened one day when the author was taking a taxi？

2.How did the taxi driver respond to the behaviour of the driver of the black car？

3.What does the taxi driver think of people according to Paragraph 3？

4.What can we infer from Paragraph 4？

If you are in a crowd, a first and most important thing is to make yourself familiar with your surroundings(周围的事物) and mentally notice alternate exits. No matter where you are, make sure you always know how to get out.

Make sure you know the type of ground you are standing on. For example, in a crowd of moving people wet ground can be dangerous, causing you to fall. You should know the general atmosphere of the event, as panic situations can often be predicted. When in danger, a few seconds can make all the difference, giving you the possibility of taking advantage of your escape route. Always stay closer to the escape route

If you find yourself in the middle of a moving crowd, do not fight against the pressure, do not stand still or sit down, because you could easily get injured or even be killed by being stepped on by other people. Instead, move in the same direction of the crowd; take advantage of any space that may open up to move sideways to the crowd movement where the flow is weaker. Keep　 your hands up by your chest, which will protect your chest during the movement.

If you fall, get up quickly. If you can’t get up because you are injured, get someone to pull you back up. If you fall and can not get up, keep moving by crawling(爬行)in the same direction of the crowd. Do not lie on your stomach or back, as this is dangerous for your body.

The worst situation is to be pushed by the crowd against an immovable object. Try to shun

High walls, as the crowd pressure can build up rapidly. After you’re pushed forward, the way you move is on a diagonal(斜线). There’s always space between people. You work your way out that way till you get out of the crowd.

1. When you are in a crowd the first thing you do is ____.

A. fight against the pressure

B. stay closer to an immovable object

C. move in the same direction of the crowd

D. be familiar with the surroundings

2.When you are in the middle of a moving crowd, ____.

A. you must go to the exit quickly

B. you must not stand still or sit down

C. you’d better stop moving forward

D. you should push your way out

3.The underlined word “shun” in the last paragraph probably means ____.

A. leave for　　　　 B. keep off
