  Different from popular thoughts, colds are not caused by bad weather. Colds are caused by viruses(病毒) in the body, and you are better out on the snowy day than you are in a warm room, with your friends, who just may be passing the virus around. If you feel a chill(寒戰(zhàn)) when you are coming down with a cold, you are already sick. A chill is an early sign of the cold.

  The virus can spread through air when a cold-sufferer(感冒患者) coughs or sneezes(打噴嚏). Surprisingly, this is not the most usual way of spreading. Many studies have now show that most colds are “caught” by hands. A cold-sufferer rubs her nose, so spreading the virus to her hand. Then a friend comes to visit her. They shake(握) their hands. The friend then gets something to eat by hand, and several days later she catches a cold. Although some parents pick up their children's tissues(紙巾) and carefully throw them away, they fail to wash their hands. They'll catch the colds, too.

  Cold viruses can also be spread by objects, for example, telephones, plates. The cold-sufferer as well as other members of the house, by washing their hands often, will stop the viruses from spreading in a way.

  Every night the stars seem to move slowly round the sky in a great circle(圓周).But one star is dif-ferent from others.It looks as if it never moved.To us, it is always in exactly the same place all thetime.It is called the Pole Star(北極星).It is not a very bright star, but it is very important.Sailors use the Pole Star to find out where they are moving to.

  The amazing(令人驚奇的)thing is that the stars are all so far away.If you travelled in the space-ship for a hundred years you would still not reach the nearest star!

  A star is really a great ball of burning gas(燃燒的氣體),like the sun.Some stars are much bigger than the sun, But they are all so far away from us that they just look like dots(圓點)of light.

  On the clearest night you can count about 2 000 stars.This may seem a lot, but with a telescope you can see many more.The better the telescope, the more stars you can see.Scientists tell us there are millions and millions of stars.No one know exactly how many there are.
