We live in the computer age. People use computers to do much of their work. But few people know how to look after them. Remember the following when you use your computer:
    ① Keep your computer in a cool ,dry room. Too much or too little heat is bad for computers. Damp (潮湿) is also bad for them.
    ② Do not let people smoke near your computer. Smoke of all kinds is very bad for many parts of a computer.
    ③ Do not eat or drink when you are near your computer. Pieces of food and a little water in the keyboard are also bad for a computer.

斗 鹅

    列宁从小就特别喜欢读书，不到五岁就识字了。上学前，他就成了图书馆的小读者啦！因为家里的书和杂志已经不够他读了。

    有一天，列宁正兴冲冲地捧着刚借来的新书回家，快到门口了，遇到邻居养的一群大鹅。大鹅不知道他手里拿的什么东西，就跑着叫着，朝着他扑了过来……

    跑，已经来不及了。如果把书扔掉，随便抓起一根棍子，就可以抵挡了。可是，不能！那样会把书弄坏的。于是，列宁把书紧紧地抱在胸前。

    大鹅一步步向他走近了。这时，列宁急得躺倒在地上，脸朝天，用两只脚抵挡这群大鹅的进攻。

    姐姐听到叫喊声，赶来了，扶起了他。幼小的列宁，衣服虽然弄脏了，可看到手中的书被保护得好好的，一本也没有弄坏，脸上露出了胜利的微笑。
