Many people catch a cold in the springtime or fall. It makes us wonder if scientists can send a man to the moon, why can''t they find a cure for the common cold? The answer is easy. There''re actually hundreds of kinds of cold viruses out there. You never know which one you will get, so there isn''t a cure for each one.
When a virus attacks your body, your body works hard to get rid of it. Blood rushes to your nose and causes a blockage in it. You feel terrible because you can''t breathe well, but your body is actually eating the virus. Your temperature rises and you get a fever, but the heat of your body is killing the virus. You also have a running nose to stop the virus from getting to your cells. You may feel miserable, but actually your wonderful body is doing everything it can to kill the cold.
Different people have different remedies for colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people take hot baths and drink warm liquids. Other people take medicines to relieve various symptoms of colds. There is one interesting thing to note: Some scientists say taking medicines when you have a cold is actually bad for you. The virus stays in you longer because your body doesn''t develop a way to fight it and kill it.
【正确答案】
B
【答案解析】According to the passage, why haven''t the scientists find a cure for the common cold? 选项B、C中的kinds of cold viruses和type of cold表明问题很可能涉及到感冒病毒或感冒的种类，因此听音频时应重点留意与此相关的内容。选项D不大符合常理，是答案的可能性很小。题干对应文中的设问句if…, why can''t they…? 其后便是答案。hundreds of kinds of 在此处等于 many kinds of。因此B项为答案。
【正确答案】
D
【答案解析】What does the speaker say about the symptoms of the common cold? 选项中的动词reveal，indicate，tell，show表明They很可能是指一种现象，结合主题分析考虑，该现象应与感冒有关。作者在提到各种感冒症状(can''t breathe well，temperature rises and you get a fever，a running nose)之后都强调出现这些症状的同时，身体实际正在吃掉、杀死病毒或防御病毒的入侵。选项D中的fighting the virus是对此的最佳概括，为正确答案。
【正确答案】
A
【答案解析】What do some scientists say about taking medicines for the common cold according to the passage? 选项C中的when combined with other remedies说明It本身也是一种治疗方法，各项中的动词does harm, cause damage, work better, help则表明问题很可能与这种治疗方法的效果有关。四个选项中只有A项”弊大于利”与文中的is actually bad for you相符合，因此A项为答案。
