March 16th is World Sleep Day. This year’s slogan (標(biāo)語) is “Breathe Easily, Sleep Well”. Its aim is to celebrate the benefits of good and healthy sleep.

Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep Foundation in the US, adults need seven to nine hours of sleep every night. For students aged 10 to 17, a healthy amount is about eight to nine hours per night.

But many students don’t get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don’t get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can’t fall asleep quickly. For others, they may even have insomnia which might keep them awake (醒著的)all night.

These sleeping problems greatly affect people’s lives. Experts have shown that lack of sleep for teenagers leads to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, the lack of sleep may make them depressed (沮喪的).

Luckily, with good sleeping habits, it is easier to fall asleep. Some of these good habits include avoiding drinks that make people excited late in the day, going to sleep at the same time each night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.

1.If Li Hong is 15years old, how much sleep does she need every night?

A. 10-12 hours. B. 8-9 hours.

C. 7 hours. D. Less than 7 hours.

2.What might happen if teenagers don’t get enough sleep?

A. They might do well in sports.

B. Their bodies and brains might grow better.

C. They might feel depressed.

D. They might not be able to finish their schoolwork.

3.The underlined word “insomnia” means “_______” in Chinese.

A. 健忘癥 B. 肥胖癥

C. 多動癥 D. 失眠癥

4.Which of the following are good sleeping habits?

a. Sleeping in a bright place. 

b. Going to bed at the same time.

c. Sleeping in a dark and quiet place.    

d. Drinking something that makes you excited.

A. a-b B. a-c

Ladies and gentlemen, today I’m going to share something amazed about dolphins. For ages, the sailors have said that it is good luck to see dolphins swimming alongside boats. Their presence meant that land is near, which will be vital informations if a boat and its crew are in danger. Some dolphins have even protected sailors which suffer shipwreck from sharks. There is no wonder that these unique and fascinating creatures have long known as our friends.

Dolphins are thought to be intelligent animals because of its quick ability to learn. They seem to communicate with each other through a combination of whistles and clicks. While scientists don’t know exact what they are talking about, it is thought that dolphins are telling each other that food is nearby, or warn each other of approaching danger.

Next fall when you see geese heading south for the winter or flying in “ V” formation (隊形), you might consider what science has discovered as to why they fly that way.

As each bird spreads its wings，it creates an uplift (上升力) for bird immediately following. By flying in “ V” formation the whole flock (鳥群) adds at least 71% greater flying range, than if each bird flies on its own. People who share a common direction arid sense of community can get where they are going more quickly and easily because they are traveling on the thrust (推動力) of one another.

When a goose falls out of the formation, it suddenly feels the drag and resistance of trying to go it alone and quickly gets back into formation to take advantage of the lifting power of the bird in front. If we have as much sense as a goose, we will stay in formation with those who are headed the same way we are. When the head goose gets tired, it flies backwards and another goose flies point. It is sensible to take turns doing demanding jobs, whether it is with people or with geese flying south.

Geese honk (雁叫) from behind to encourage those up front to keep up their speed. What do we say when we honk from behind?

Finally and this is important, when a goose gets sick or is wounded by gunshots, and falls out of formation, two other geese fall out with that goose and follow it down to lend help and protection. They stay with the fallen goose until it is able to fly or until it dies, and only then do they launch out on their own, or with another formation to catch up with their group. If we have the sense of a goose, we will stand by each other like that.

1.The first three paragraphs chiefly deal with .

A. scientific discovery about geese.

B. the importance of flight formation.

C. the advantages of “V” formation.

D. the reasons for geese’s flight.

2.The phrase which can best replace “stand by” in the last sentence is “ ”.

A. be against. B. support.

C. sit by. D. obey.

3.What does the author want us to learn from the geese?

A. Teamwork. B. Sympathy.

C. Kindness. D. Intelligence.
