Air-conditioners

In recent years, the air- conditioner has become one of the many indispensable electrical appliances for thousands upon thousands of families, especially those in the south, where the intense heat overwhelms the earth throughout the summer. The advantages of the air- conditioner are self - evident. Armed with the ability to refrigerate, the air- conditioner makes you feel refreshing and comfortable no matter how hot it is outside. Thus it guarantees the efficiency of your work and the quality of your rest. Without it there would be no knowing what would happen to you in the dog days. Moreover, it can also create a proper condition in summer for the operation of computers -- the best friends of yours in the information age. Too high a temperature would make computers work improperly, causing much inconvenience for your daily life and work.

With all the advantages the air- conditioner offers, its disadvantages are also obvious. To begin with, the installment of the air - conditioner always involves the hole making in the wall, which undoubtedly makes the wall less pleasing to the eye than if not. Besides, the air- conditioned environment may make you more and more dependent on the air - conditioner, thus physically weakening your ability to cope with hot weather. Most important, the air - conditioned environment provides poor ventilation, and sometimes may even give rise to a strange kind of smell, which makes you feel dizzy and sick. Consequently, you will be in no mood for enjoying the cool air produced by the air- condi-
tioner.

All things considered, I think its advantages outweigh its disadvantages. Actually, nothing in the world is perfect. It is unwise to make light of the favorable aspects of a thing on account of its unfavorable aspects. The same is true of the attitude you take towards the air - conditioner.

A person may also become knowledgeable through other ways such as listening to the radio or watching television. The best way to acquire knowledge, however, is through reading.

Reading as a means of obtaining knowledge has a number of advantages over many other ways. To begin with, it is the most consistent way of getting knowledge. One can read regularly but few people can travel in the same way. Secondly, reading can ensure a thorough grasp of what you are interested in. This is hardly so when one is listening to the radio or watching TV. Finally, reading is the most flexible of all the ways to obtain knowledge. For example, one can always read for ten minutes before going to bed, but it is not always possible for him to converse with others at such a late hour.

However, there exists one problem about reading. There are all kinds of Books in society. Some are good, while others are bad.
