What does it feel like to break a bone (骨頭)? It’s different for everyone, but the pain is often sharp (嚴(yán)重). If the break is small, however, the person may not feel much pain at all. If you think that you or someone else has broken a bone, the most important things to do are to stay calm, make the hurt person comfortable, and call the doctor. Do not move the injured body part since movement could make it worse.
To treat the break, the doctor will need to take an X-ray. This gives the doctor the information he or she needs to set (接上) the bone: to put it back to its normal place. If the bone is large or it is broken in more than one place, the doctor may need to use metal pins (鋼釘) to set it. After the bone has been set, the next step is usually putting on a cast, the special, hard thing that will keep the bone in place for a month or two.
Your bones are excellent at healing themselves. Broken bones will produce many new cells (細(xì)胞) and tiny blood vessels (血脈). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.
【小題1】 Which of the following is the best title for the passage?
A．How to Know if a Bone is Broken
B．How Broken Bones Heal Themselves
C．Common Causes (原因) of Broken Bones
D．What You Should Know about Broken Bones

A．a(chǎn)sking the doctor for helpB．comforting the hurt person
C．moving the injured partD．staying calm

a. take an x-ray  b. use metal pins to set it  c. put it back to its normal place  d. put on cast
A．a(chǎn)→b→c→dB．a(chǎn)→c→b→dC．a(chǎn)→d→c→bD．d→a→b→c
【小題4】The underlined word “heal” in Paragraph 3 is closest in meaning to “______”.
A．break againB．become worse C．wound or hurtD．become healthy again
【小題5】 Where would you probably read this passage?
A．In a story book.B．On a poster.C．In a health care book.D．In a chemistry book.

閱讀短文，根據(jù)短文內(nèi)容回答問題。（共10分，每小題2分）

Homework is a big part of going to school. Unluckily, homework has to be done outside class—during times when you would probably much rather be doing something else, for example, you like going to a birthday party instead of copying out a whole Chinese text. Luckily, there are several things you can do to make homework less work

First, be sure you understand the task. Write it down in your notebook if you need to, and don’t be afraid to ask questions about what’s expected. If you want, you can also ask how long the special homework task should take to finish, so you can plan your time.

Second, use any small pieces of time you have in school to work on your homework. Many schools have study halls that allow students to study or get homework done. The more work you can get done in school means the less you’ll have to do that night.

What if you don’t have time in school to get homework done? You’ll need to think about how much homework you have for a given night and what else is going on that day, and then plan your time. Most high school students have more than two hours of homework a night. If it’s a heavy homework day and it seems like you got a task in every subject but gym and lunch, you’ll need to spend more time on homework. It’s a good idea to come up with some kind of homework timetable, especially if you enjoy sports or activities or have an after-school job.

1.Is homework a big part of going to school?

2.What do students like doing outside class?

3.Where can students study or do their homework in school?

4.How long do most high school students spend on their homework a night?

5.What advice does the writer give students on homework in the passage?
