本文主要讲述了年轻人不仅要会用电脑而且要学会维护电脑，不能放在潮湿的地方，也不能放在特别冷或特别热的地方，要保持电脑键盘的整洁。眼睛和屏幕要保持高度一致，并最好使用电脑专用眼镜。

【1】根据上文Keep your computer in a cool, dry room.以及后面的Moisture (潮湿) is also bad for them.可知这里说的是电脑存放的环境，根据所给选项，B选项意思是太热或太冷都对电脑不好，故选B。

【2】根据后文Smoke of all kinds is very bad for many parts of a computer and can cause many problems.可知这里说的是任何形式的烟都对电脑不好，结合所给选项，故选E。

【3】根据后文描述Pieces of food and even a little water in the keyboard can also cause many problems.键盘里的食物碎屑和水会导致很多问题，故这里说不要让食物和水靠近你的电脑，故选C。

【4】根据前文Make sure that the keyboard and screen (屏幕) are the correct height (高度) for you.所以如果键盘和屏幕高度不合适的话，会导致我们身体不适，故选D。
