We know mosquitoes very well. Mosquitoes fly everywhere. They can be found almost all over the world, and there are more than 2,500 kinds of them.
No one likes mosquito. But the mosquito may decide if she loves you. She? Yes, she. The male(雄性) mosquito doesn’t bite! Only the female(雌性)mosquito bites because she needs blood(血)to lay eggs. She is always looking for things or people she wants to bite. If she likes what she finds, she bites. But if she doesn’t like your blood, she will turn to someone else for more delicious blood. Next time a mosquito bites you, just remember you are chosen. You’re different from others!
If the mosquito likes you, she lands on your body without letting you know. She bites you so quickly quietly that you may not feel anything different. After she bites , you will have an itch(痒) on your body because she puts something from her mouth together with your blood. When the itch begins, she has flown away.
And then what happens? Well, after her delicious dinner, the mosquito feels tired. She wants to find a place to have a good rest. There, in a tree or on a wall, she begins to lay eggs, hundreds of eggs.

小题1:Mosquitoes means “蚊子” in Chinese.
小题2:All mosquitoes like to bite people for blood.

解析

试题分析:这篇短文介绍了蚊子的相关知识。雄性蚊子并不咬人,雌性蚊子因为需要血来产卵所以会吸血。它们会选择自己喜欢的血型来咬,而且咬的速度很快,让你都感觉不到异样。等你感到疼痛时,它已经飞走了。吸完血后它要找个地方休息然后产卵。
小题1:词意推测题。根据文中描述得知,文章描述的mosquito即为“蚊子“,故此题正确。
小题2:细节理解题。根据文中第二段内容The male(雄性) mosquito doesn’t bite!雄性蚊子并不咬人;故此题错误。
小题3:细节理解题。根据文中第四段内容Well, after her delicious dinner, the mosquito feels tired.在吃完美味的晚餐后,蚊子会觉得累;故此题错误。
小题4:细节理解题。根据文中第三段内容She bites you so quickly quietly that you may not feel anything different.它咬你很快,你可能都感觉不到有异样;故此题正确。
小题5:细节理解题。根据文中第三段内容When the itch begins, she has flown away.当疼痛开始的时候,它已经飞走了。故此题正确。

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.

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.
小题1: Scientists worry that_______ may cause children to sleep less.
A.too much homework
B.pressure from parents
C.TV and computer games
D.parents’ bad sleeping habits
小题2: Scientists did the new study in order to know_______.
A.why children can’t get enough sleep
B.how long children should sleep every night
C.what children like to do before they go to sleep

小题3: Who helped do some new study, children with less sleep_______.
A.Teachers. B.Parents. C.Scientists. D.Psychologists.
小题4:According to the new study, children with less sleep_______.
A.were more likely to feel excited
B.were more active in playing games
C.had more problems paying attention
D.didn’t want to answer questions in class
小题5:The new study was done in_______.

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.
