题目内容
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.

黎明文化寒假作业系列答案Long, long ago there was a very foolish thief. Do you know what he did one day? When he wanted to steal (偷) the bell on his neighbor’s door, he walked up to the door, took hold of (抓住) the bell and pulled hard. The bell made a very loud noise. The thief was afraid and went home.
Then he sat down to think, “I must do something about the noise,” he said. He thought and thought. At last he had an idea. “Ah, I’ll put some cotton in my ears.
