Do you know that it is your own immune system working against the virus that makes you uncomfortable when getting a cold, but not the virus itself? So when you have got a strong immune system and the virus is strong enough too, you will possibly get terrible cold symptoms( 症状) ?
Vitamin C won’t stop a cold
It is claimed that Vitamin C helps by increasing white blood cells. However, many tests have shown that it does not prevent colds. At best, it only slightly reduces the rime of symptoms.
Staying indoors won’t protect you
One of the most likely sources of cold viruses is your computer mouse or desk. A study of the cold virus in offices found that 47% of desktops, 46% of computer mice and 45% of telephones had cold viruses on them.
Wrapping up warm won’t protect you
Colds are more common in autumn and winter. That’s because the cool, wet and cold weather drives people indoors, where viruses may more easily jump from one person to another. And the distinct peak in colds(感冒高峰) is in September and early January, which is likely due to the return of students to schools and colleges after the summer and winter vacation.

Americans use many expressions with the word dog. People in the United States love their dogs and treat them well. They take their dogs for walks, let them play outside and give them good food and medical care. However, dogs without owners to care for them lead a different kind of life. The expression, to lead a dog’s life, describes a person who has an unhappy existence.
Some people say we live in a dog-eat-dog world. That means many people are competing for the same things, like good jobs. They say that to be successful, a person has to work like a dog. This means they have to work very, very hard. Such hard work can make people dog-tired. And, the situation（状况） would be even worse if they became sick as a dog.
A Cavalier King Charles Spaniel (the name of a kind of dog), is groomed for months before competing in the Oklahoma City Summer Classic Dog Show and can be the winner sometimes. So people say every dog has its day. This means that every person enjoys a successful period during his or her life. To be successful, people often have to learn new skills. Yet, some people say that you can never teach an old dog new tricks. They believe that older people do not like to learn new things and will not change the way they do things.
Some people are compared to dogs in bad ways. People who are unkind or uncaring can be described as meaner than a junkyard dog(比垃圾场的狗更凶狠). Junkyard dogs live in places where people throw away things they do not want. Mean dogs are often used to guard this place. They bark or attack people who try to enter the place. However, sometimes a person who appears to be mean and threatening is really not so bad. We say barking dogs never bark.
Dog expressions are also used to describe the weather. The dog days of summer are the hottest days of the year. A rainstorm may cool the weather. But we do not want it to rain too hard. We do not want it to rain cats and dogs.What does this passage mainly talk about?
