The food guide pyramid(金字塔)was the model for healthy eating in the United States. Now it has been replaced(代替)by a colorful plate—called MyPlate—with some of the same messages: Eat different kinds of foods, and eat less of some foods and more of others.
The pyramid has six parts to show the five food groups and fats, oils and sweets. Basic(基本的)foods are at the bottom(底部)and include bread and rice. In two middle parts are vegetables and fruits. In two top parts are milk and cheese, and meat, fish, eggs and so on.
The plate has four parts: vegetables, fruits, grains, and protein, and a side order of dairy(乳制品)in blue. The big message is that fruits and vegetables take up half the plate and the vegetable part is a little bigger than the fruit part. The grain part is bigger than the protein part. The MyPlate seems to be encouraging us to eat different food groups at each meal.
First Lady, Michelle Obama, has introduced the plate. And she will use it with her family. She said the pyramid just wasn’t easy enough for parents and kids to follow.

核心考点
试题【The food guide pyramid(金字塔)was the model for healthy eating in the United States】;主要考察你对科普环保类等知识点的理解。[详细]
举一反三
In America, most people don’t get enough sleep. Children aged 5 to 12 are advised to sleep 10 to 11 hours every night, but most of them can’t sleep that long. A study found that about 41 million American workers got less than six hours of sleep every night. Scientists worry that parents are passing their bad sleeping habits down to their children.
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.

Last week, 169 Junior One students at No. 35 Middle School of Shenyang took their first no teacher exam. After the teacher handed out the exam papers, he left the room and never came back. A student collected in the papers when the exam was over.
“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.
小题1:Why did No. 35 Middle School of Shenyang hold a no – teacher exam?
A.Because the teachers were too busy with their work.
B.Because it wanted to show the students the importance of honesty.
C.Because the students didn’t need their teachers to invigilate.
D.Because the headmaster wanted to know who cheats in exams.
小题2:How many students don’t agree to no-teacher-exams mentioned in this passage?
A.OneB.TwoC.ThreeD.Four
小题3:What does the underlined word “them” in the last paragraph refer to(指代)?
A.StudentsB.TeachersC.InvigilatorsD.No-teacher exams
小题4:Which of the following is TRUE according to the passage?
A.More students will cheat if there are no invigilators in exams.
B.No-teachers exams can make students honest and get good grades.
C.Most students are worried about having no invigilators in class exams.
D.Some students may feel relaxed if there are no invigilators in exams.

What is the first thing you want to do when you see someone yawn(打哈欠)?You want to yawn, too! Yawning is contagious.
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.
小题1:The underlined word “contagious” in Paragraph 1 means _________.
A.helpful to our health

C.hard to understand
D.getting into one trouble after another

③People yawn to cool down their brains  
④People yawn to get rid of carbon dioxide.
