It makes us wonder . why can't scientists find a cure (疗法) for the common cold if they can send a man to the moon? The answer is easy. There are hundreds of kinds of cold viruses (病毒) 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 brings congestion (堵塞) with 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 runny 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 ways of dealing with colds. In the United States and some other countries, for example, people might eat chicken soup to feel better. Some people drink warm water. Other people take medicine. There is one interesting thing to notesome scientists say taking medicine when you have a cold is actually bad for you. The virus stays in you longer because your body doesn't have a way to fight with it and kill it. Bodies can do an amazing job on their own. There is a joke, however, on taking medicine when you have a cold. It goes like this： It takes about 1 week to get over a cold if you don't take medicine, but only 7 days to get over a cold if you take medicine. 【文章大意】 本文是说明文，话题是日常生活类。文章主要说明了感冒的症状和应对感 冒的方法。 1Why does blood rush to our nose when we have a cold?

But in my research, I've found that the truth is quite different. Technology, it turns out, has made being alone seem like a problem that needs solving. When young people are alone, even for a minute or two, they feel the need to connect, to get on Facebook or some other social networks and chat. But in connecting, they often end up feeling more isolated. Why? Because by being in constant (不断的) connection, they lose the ability to feel satisfied with their own company (独处) Facebook can help us keep in touch with our friends, but we too often use it instead of spending facetoface time with them. And since we feel the need to keep up with them online, we don't have moments of loneliness where we can collect our thoughts and learn how to be comfortable being alone. Sherry Turkle, Professor Facebook connects more of us to more of our friends and family in more places than we have ever been connected before. Yes, Facebook is a huge time sinkmaybe the biggest ever. Many people post useless stuff. And seeing too much of your friends' lives can make you jealous (嫉妒的), but it won't make you lonely. Jane，a former student of mine, who is back in New York after living abroad for ten years, told me that Facebook helps her a lot. The first time she moved back to New York from abroad, she felt disconnected from her family and friends. Now, because of lots of photos and information updates (更新), she knows what is happening with her friends all the time. In fact, if you are lonely in real life，you will be lonely online as well.
