In the study, Reut Gruber and some other scientists either added or reduced on hour of sleep for healthy children aged 7 to 11. They watched the children for five nights. They wanted to know if the amount of sleep can affect a child’s behavior.
Before the study began, students were asked to sleep the same amount of hours as usual. Their teachers were asked to record their behavior. After five nights of the records, scientists found that those who slept one hour less behaved worse than those who slept one hour more. Students with less sleep were more likely to feel sad and had more problems paying attention.
The scientists chose to study children in their homes instead of in a laboratory, because they wanted to find out how everyday changes might affect children’s behavior at school. “In the study, nobody became a talent, and nobody became crazy. But small changes in children can really make a big difference,” says Gruber.

“That test was not only a test of knowledge, but also a test of morality(道德). We wanted to show the students how important honesty(诚实)is,” said the school’s headmaster. Next year, it wants 80% of its exams to be without teachers. But students have different ideas.
“I was happy and excited during the exam because my teachers trusted(信任)me,” said a 15-year –old girl in Class 11.
“Schools must trust students a lot and do not use invigilators(监考人)in exams. But I think it is too early. Some students will cheat(作弊)if there are no invigilators. And the students will not be able to ask for help when they need,” said another student.
“I don’t like having invigilators in exams. When they walk around the classroom, they make me nervous. I would get higher marks without them in the room because I would feel more relaxed,” a third student said.
“I think it’s very important to have invigilators in exams. Many students want to check their answers with each other after they have finished papers. And invigilators can also keep the classroom in order when something unusual happens. They may make me nervous, but I still think we need them,” a girl student said.
No-teacher exams may be a good idea. But before using them, schools must tell students the importance of honesty and try to find ways to solve something unusual in exams.

A.More students will cheat if there are no invigilators in exams. |
B.No-teachers exams can make students honest and get good grades. |

D.Some students may feel relaxed if there are no invigilators in exams. |
Scientists have found that all people yawn. Babies start to yawn even before they are born. The earliest yawn takes place when a baby is still inside its mother. When young children are about one year old, they start to yawn when they see others yawning. That’s why scientists seem to think yawning is contagious.
It’s no secret that yawning is contagious, but why do we yawn? Well, scientists are not really sure.
Some think we yawn because we feel bored. Recently scientists studied two groups of students between the ages of 17 and 19. One group watched music videos, and the other watched a boring color test. Scientists compared the numbers of their yawns and found that the color test group yawned more times than the video group.
Another reason for yawning has to do with breathing. Some scientists believe that when we are bored or tired, we breathe more slowly. As our breathing slows down, we cannot get rid of (去除)enough carbon dioxide, our bodies will tell the brains(大脑)to breathe deeply. The result is a big yawn.
In 2007, scientists suggested a new reason. They said that the reason why people yawned was to cool down their brains. These scientists found that people who were warmer than others yawned more often.
Scientists are still trying to find out why yawning happens and why it is so contagious. But they are only sure that when one person yawns, almost everyone else nearby wants to yawn, too.
