阅读理解Whatdoesitfeelliketobreakab

阅读理解What does it feel like to break a bone (骨头)? It’s different for everyone, but the pain is often sharp (严重). 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 fortable, 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 (钢钉) 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 (细胞) and tiny blood vessels (血脉). These cover both ends of the broken part, and close up the break until the bone is as whole and strong as before.1.Which of the following is the best title for the passage?A.How to Know if a Bone is BrokenB.How Broken Bones Heal ThemselvesC.Common Causes (原因) of Broken BonesD.What You Should Know about Broken Bones2.When someone breaks his bone, the following should be done except ______.A.asking the doctor for helpB.forting the hurt personC.moving the injured partD.staying calm3.Which is the correct order to treat the break? a. take an x-ray  b. use metal pins to set it  c. put it back to its normal place  d. put on castA.a→b→c→dB.a→c→b→dC.a→d→c→bD.d→a→b→c
