    A cold is the most common illness among us.这里有一些建议来防止感冒。

    Drink lots of hot water. This is an effective way to stop a cold. You'd better take at least 8 to 10 glasses a day.

    Check your temperature often. If your temperature is lower than 102 degrees F, don't care much about it. With your body temperature being higher than normal, it will be difficult for the viruses (病毒)to grow. In other words, having a low-grade fever (up to 102°F) is your body's way to protect itself from viruses.

    Make your sore throat feel better. Chicken soup or any kind of sour soup you like, is an excellent choice.

    Gel enough rest and slay warm. You should get enough sleep. Make sure to keep yourself warm and dry because you may feel cold at that time. If you are starting to sweat a lot, change your clothes immediately. You do not allow your sweat to just dry especially on your chest and back. As much as possible, wear cotton-made clothes to allow your skin to breathe and make you feel more comfortable.

    Long long ago there was a thief. Do you know what he did one day？When he wanted to steal(偷)the bell on his neighbour'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(棉花)in my ears. Then I won't be able to hear the noise." The next day he went to the door of his neighbour, and took hold of the bell. This time he pulled even harder. The bell rang loudly, but the thief did not hear anything. With another hard pull he got the bell off the door. Just then the neighbour came out.

    "Steal my bell? I'll teach you a lesson," the angry man shouted. And he hit the thief on the nose.

    The thief did not know how the neighbour found out he was stealing the bell." Why did he come out just then?" he wondered.

    Do you know what makes lightning (闪电)? {#blank#}1{#/blank#}

    Lightning strikes happen when ice and water in clouds rub (摩擦) together, and cause atmospheric (大气层的) changes. When this happens, it creates a static charge (静电). Lightning can strike inside the cloud, between two clouds or between a cloud and the earth. {#blank#}2{#/blank#}

    Lightning can be very dangerous. Every year, lightning kills people because it can start big fires or because it reaches a temperature of 28,000℃. About 1,000 people are hit by lightning every year in the United States, and about 100 of them die as a result.

    {#blank#}3{#/blank#}Scientists think that there are more than three million lightning strikes every day in the world. An American man, Roy Sullivan, who worked in a park, survived from the most lightning strikes. {#blank#}4{#/blank#}And he keeps the highest world record.

    Lightning is sure not something to play with. When lightning strikes, it's best to stay inside a large building. {#blank#}5{#/blank#}Also, do not lie down on the ground, or the electricity may go through you and cause a heart problem.
