题目列表(包括答案和解析)

Good Housekeeping has discovered that even if a child wear a helmet when she bikes, or skates, it may not protect her from a serious head injury.

Every year, 390,000 children under age 15 go to hospital emergency rooms with bike-related injuries. Of that number, about one third children suffer head injuries and an estimated 200 die. By wearing a helmet, a child can reduce her risk of injury by as much as 85 percent. But remember —— a bicycle helmet must fit properly to be safe. Here are five steps to making sure your child's helmet fits properly.

1) If you haven't bought your child's helmet already, you might want to consider one with a rear stabilizer(稳定杆). A rear stabilizer holds the back of the head gently and helps the helmet stay correctly positioned.

2) The helmet should fit closely and shouldn't slide from side to side or front to back. If your child can put two fingers on both temples inside the helmet, it's too big. Try a smaller size. But if the next size down is too small, use the fit pads(护垫). Fit pads come in different sizes and attach to the helmet with Velcro.

3) Tell your child to open her mouth widely and ask if she can feel the helmet push down onto the top of her head. If she can't, you need to readjust her helmet.

4) To prevent strap slippage, wind a rubber band around the strap where it meets the fastener.

5) Recheck the fit regularly.

You should replace the bicycle helmet:

If she has been in an accident with it.

If the buckle(金属扣) breaks or if a piece breaks off.

If it doesn't have a U.S. Consumer Product Safety Commission, American Society for Testing and Materials, or Snell Memorial Foundation sticker.

If it doesn't fit correctly. Even if the helmet fit perfectly two years ago, it might be too small now.

1.Who is this passage mainly written for?

A. She must buy a smaller size.               

B. She can use some fit pads.

C. She can put fingers on both temples inside the helmet.

阅读理解。
     One end of the lamp wick (灯芯) is immersed (把......浸入......之中) in oil and the other end is not
immersed. When you light the end which is not immersed, it will burst into flame. This is because the oil
is able to rise up the lamp wick thus helping it to burn.
     In the same way, if you immerse the end of a piece of chalk into a glass of water, the water will soon
climb up the chalk making it wet.
     If a piece of ordinary glass tubing is heated in a gas flame until it becomes soft, it can be pull into a tube
of a very small hole. Immerse the tube into water or any other liquid which wets glass, you will find that
the liquid rises to a height of several centimeters. This is known as capillary action. The liquid rises because
there is an attractive force between the liquid and the glass. The attractive force depends on the diameter of
the tube and the type of liquid used.
1. Why can an oil lamp work?
[     ]
A. Because there is oil.
B. Because there is oil climbing up the wick.
C. Because the other end is immersed.
D. Because the wet end is lighted.
2. The passage mentions all the things except _____.
[     ]
A. oil
B. water
C. chalk
D. paper
3. The last sentence means that _____.
[     ]
A. the thinner the diameter, the greater the attractive force
B. the diameter of the tube and the kind of the liquid decide the greatness of the force
C. the thinner the diameter, the smaller the attractive force
D. oil climbs up higher than water
4. The liquid rises up a tube because _____.
[     ]
A. the tube is thin
B. the glass has an attractive force
C. the liquid tends to rise up
D. both glass and liquid act on each other
5. The passage mainly talks about _____.
[     ]
A. an oil lamp B. an ordinary tubing
C. liquid climbing up things
D. capillary action

The benefits of keeping a journal (日志)

If you want to grow, one important thing you should do is keeping a journal. It may seem simple, but it can make a big difference in your life. I have been keeping journals for years. Writing all the lessons I learn and all the ideas I get has become a habit for me.    1.   Here are some benefits you will get by keeping a journal.

◆ It prevents you from losing an idea. Have you ever gotten an idea only to lose it later because you didn’t write it down?   2.   But then I developed the habit of writing down every idea that came into my mind as soon as possible. If I’m away from my computer, I usually write it down on a piece of paper that I bring wherever I go. I will then transfer the idea to the journal in my computer.

◆ It helps you review all the lessons you’ve learned. By reviewing your journal, you can quickly see the lessons you’ve learned and the ideas you’ve gotten.    3.   You can use the ideas to propel (鞭策) yourself forward.

   4.   After keeping a journal for years, you can look back at it and see how far you’ve gone. Things that were big problems in the past might seem small today. The raw ideas you had in the past might have been realized today.

◆ It helps you expand your ideas. When you try to come up with a sentence to express an idea, you are thinking actively about it.    5.   In the end, you will expand your ideas.

A.I often experienced that myself.

B.It trains you to express your thoughts.

C.It allows you to see your progress over time.

D.Just use whatever tool you feel comfortable with.

E. Thinking actively helps you connect your idea to another idea.

F. And to be honest, I can’t imagine what my life would be like without it.

G. Then you can do whatever necessary to avoid repeating the same mistakes.
