What is the reason for pain? Pain hurts us, but could it be good for us? Is pain in fact helpful?
Pain is the body's way to tell us that something is wrong so that we stop what we are doing to protect the body. For example, if you break your leg, pain stops you from walking on it. If you didn't feel any pain, you would continue walking around and you could hurt your leg more. But why does it continue to hurt even after you have stopped walking on your injured leg? That is
because your body needs you to rest in order to have the energy to mend the broken bone.
But how does pain work? We have special cells in our skin, in our eyes, and inside our bodies, too. When something goes wrong, these cells send messages to the brain. The brain then makes us feel pain so we will stop doing whatever is causing the pain. Put your hand on a hot pan, and your hand's skin cells tell your muscles and your brain. Your muscles are able to quickly move your hand away from the heat. At the same time, your brain gets the message that something is wrong and that you need to care for your hand. These things all happen in less than a second.
But do you know that the brain itself cannot feel pain? In fact, sometimes when doctors perform an operation on the brain, they do not put the person to sleep. Because the person does not feel any pain in the brain, it is thought to be much safer if the person is awake while the doctors work.

答案
文章主要介绍了疼痛的原因、作用和工作机制。
1. A 词义猜测题。根据文章第一段中“That is because your body needs you to rest in order to have the energy to mend the broken bone.”可知，你的身体需要你休息，以便有能量来修复骨折，因此mend的意思是“修复”，与heal意思相近。
2. A 推理判断题。根据文章第一段中“If you didn't feel any pain, you would continue walking around and you could hurt your leg more.”可推知，无法感知疼痛的人更经常受伤。
3. B 细节理解题。根据文章第三段中“Because the person does not feel any pain in the brain, it is thought to be much safer if the person is awake while the doctors work.”可知，因为大脑本身感觉不到疼痛，所以医生操作时患者保持清醒更安全。
4. B 主旨大意题。根据文章第一段中“Pain is the body's way to tell us that something is wrong so that we stop what we are doing to protect the body.”以及全文可知，文章主要讨论疼痛如何帮助身体自我保护。
