Have you ever seen people building houses? To build a house , you need workers. They use their hands , tools(工具) and machines to put things together. Building the ISS（國際太空站） is the same. The difference is that the workers are astronauts. They walk in space and use robots’ arms and hands to do their work.
In the space station ,astronauts are comfortable. The temperature there is about 21℃.But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(陰暗處)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes----spacesuits.
Spacesuits also keep astronauts safe from flying rubbish(垃圾)in space.Each time people go into space , they leave rubbish there. So astronauts should be careful because there’s a lot of rubbish, some rubbish goes many times as fast as a plane !
Space walking is not easy , and it can be dangerous. So getting ready for it takes a lot of time to learn. Astronauts will need to do 160 space walks to finish their work in the ISS. That will take about 1,900man-hour of work.
小題1:What’s the temperature in the space station?
A. 21℃            B120℃             C. -85℃               D.-21℃
小題2:The astronauts work in space with                  
A．scientists’ handsB．tools in their hands
C．robots’ arms and hands D．workers’ hands
小題3:Which of following is TRUE according to the passage?
A．Space walking is very comfortable
B．Space walking is difficult
C．Astronauts needn’t wear spacesuits when walking in space.
D．Space walking is very safe
小題4:What does the underlined word“spacesuit”mean in Chinese?
A．太空服B．防暴服C．羽絨服D．雨衣
小題5:Which of following is not TRUE according to the passage?
A．Spacesuits can keep astronauts warm
B．Spacesuits can keep astronauts safe
C．Flying rubbish in space goes very slowly
D．Outside the station ,it can be too cold or hot for people.

小題1:A
小題1:C
小題1:B
小題1:A
小題1:C

小題1:A太空站的溫度是多少？根據(jù)In the space station ,astronauts are comfortable. The temperature there is about 21℃.所以選A。
小題1:C宇航員在太空中用什么工作？根據(jù)use robots’ arms and hands to do their work，順藤摸瓜，所以選C.
小題1:B 根據(jù)文章下面那句話是真實的？根據(jù)文中But outside the station , it can be too hot or cold for people. In the sunlight, it’s about 120℃. In the shadow(陰暗處)of the station, it’s about -85℃ . So when astronauts walk in space , they have to wear heavy clothes，所以在太空中行走是很困難的。
小題1:A space 太空，空間；Suit，套裝，合成詞太空服。根據(jù)文意也可推斷是太空服。
小題1:C根據(jù)文意那句不是真實的？some rubbish goes many times as fast as a plane，這句話說一些垃圾的速度是飛機的好幾倍，所以C 跟文意不符。

All students need to have good habits(好習(xí)慣): When you have good study habits, you learn things quickly. You also remember them easily.
Do you like to study in the living room? This is not a good place because it is usually too noisy. The telephone bell rings there; the TV is there, and sometimes it is a good place for your pet dog or cats to play and rest. You need to study in a quiet place, like your bedroom. A quiet place will help you only think about one thing, and you will learn better.
Before you begin to study, do not forget to clean your desk. A good desk light is important, too. You’ll feel tired easily if there is not enough light(光線). So you should have a clean and bright lamp. To tell you the truth, the most important is that you should put your heart into your study.

閱讀短文，根據(jù)其內(nèi)容回答問題。
Phys ed (physical education) is making a comeback, but with a difference. The new way is to teach skills that are useful beyond gym class, like lifting weights, balancing their diets and building physical endurance（耐力）.
Considering that 15% of American children 6 to 18 are overweight, supporters say more money and thought must be put into phys ed curriculum. In many cases, that may mean not just replacing the old gym-class model with fitness programs but also starting up phys ed programs because school boards（教育委員會）often “cut P.E. completely or decrease（減少）its teachers or the days it is offered,” says Alicia Moag-Stahlberg, the director of Action for Health Kids. The difference in phys ed programs is its short of a national standard.
The wisdom of the new idea has some scientific support. Researchers at the University of Wisconsin have showed how successful the fit-for-life model of gym class can be. They observed how 50 overweight children lost more weight when they cycled and skied cross-country than when they played sports. The researchers have also found that teaching group sports like football results in less overall（全體的）movement, partly because the students who are unwilling to do may sit on the bench.
Another problem with simply teaching group sports in gym class is that only a small part of students continue playing them after finishing their high school. The new method teaches skills that translate to adulthood, which means kids are given skills and experiences so they can lead a physically active life in their future.
小題1:Is the new Phys ed program different from the one before?
小題2:What does the new P.E. program teach the students?
小題3:According to the passage, what do some school boards do with P.E?
小題4:What are the problems with simply teaching group sports?
小題5:What’s the passage mainly about?

Sitting on exercise balls brings more than a smile to students and teachers.
Some fourth-graders at Conrad Weiser West Elementary School in Womelsdorf love their new chairs-—probably because they're not really chairs at all.
The kids are sitting on the air-filled balls. But different from those just for exercise, these have small legs that keep them from rolling. Sitting on a chair all day in school can make anyone want to move around. So, more and more teachers are letting students have a ball. By using exercise balls instead of common chairs, teachers find students' posture(姿勢) and attention improved.
Dotti Pownall, a fifth-grader teacher in West Virginia, has been using balls as chairs since December 2008. "The students love them." she says. Pownall took a survey of her students. She found that 80 percent, thought sitting on the balls helped them concentrate(專注) better:
"Besides, they’re fun,b" says Pownall.
According to WittFitt,b a company that has sold balls to more than 200 schools, they can improve kids' posture and classroom behavior.
Exercise ball chairs are getting popular in classrooms, from preschool to college. Some adults (成人) even use them at work.
Lisa Witt felt so strongly about the use of balls as chairs that she started WittFitt. She said the company not only encourages the use of balls but also educates teachers and students on how to use them. "We sell balls in 24 states in America, three provinces in Canada and Japan." says Witt.
小題1:Sitting on exercise balls can______.
A．improve students' attentionB．make students smarter

小題2:According to the passage, the company WittFitt______.
A．began to produce balls in 2008 B．sells balls in 24 countries

A．exercise balls have no legsB．Pownall works as a teacher
C．students hate exercise balls D．exercise balls are filled with sand
小題4:The passage mainly tells us about______.
