Everyone knows we can’t live a happy life without good health. As for students, we can’t study well if we don’t have enough sleep. Sleep is important to everyone as well as students. However, 【1】 start before 8:00am, which means that most students have to wake up at about 6:30am. This makes 2 almost impossible for teenagers to sleep for nine hours that the National Sleep Foundation(NSF, 国家爱睡眠基金会) suggested. Students’ health condition and their grades would 3 if teenagers could sleep for as long as the suggested number of hours.

4 to the NSF, it is normal for teenagers to go to bed late. Only about 15% of teenagers fall asleep 5 10:45pm, about 5%go to bed about 10:45, and about 80% go to bed after 11:00pm. Many teenagers have sleeping problems.

What’s more, doctors say that lack(缺少) of sleep is the top health problem. If it is true, why can’t something be 6 to help students get more sleep? Studies show that teenagers who sleep for nine and a half hours are late for class less often and have 7 health problems.

Another benefit(益处) of starting classes later is that students’ grades would improve. Enough sleep helps students pay more attention to 8 their teachers say. And then they can have more chances to get better grades.

It is really important for teenagers to get enough sleep so that they may stay healthy and get good grades. To let students make it, classes do need to begin later.

【题目】The first robot was invented in the 1920s. Robots have appeared in many American films. In some films, they are stronger, faster and cleverer than people.

In real life, robots are mainly used in factories. They do some dangerous and difficult jobs for humans. Robots also help disabled people, for example, blind people. Today many blind people have a guide dog to help them. In the future, guide dogs might be robot dogs.

One kind of robot guide dog has wheels. It moves in front of the owner. It is very clever. It knows the speed of its owner’s walk. The owner wears a special belt. The belt sends instructions to the owner from the dog, such as “Stop here” “Turn left” or “Turn right”.

In the United States, another kind of robot helps disabled people to take care of themselves in their daily life. The robot hears the sound of its owner’s voice. It follows instructions such as. “Turn the page” or “Make a cup of coffee”.

Robots are also used in American hospitals. They can do simple jobs. At one hospital, for example, a robot takes meals from the kitchen to patients’ rooms. It never gets lost because this robot has a map of the hospital in its computer memory.

Though robots can help people in many different ways, they will never take the place of humans.
