　　Electronic Dictionaries

　　In recent years electronic dictionaries have become very popular as a study aid among students.

Compared with a traditional dictionary, this kind of new dictionary has many advantages. First, in comparison with a traditional dictionary, it is obviously very handy and convenient. Besides, due to its multifunction, it is also very helpful. It can not only translate words from English to Chinese, but vise versa. Some even can teach a learner how to pronounce a word. Most important of all, most of the entries in electronic dictionaries are comparatively updated.

On the other hand, an electronic dictionary has its disadvantages. To begin with, the definitions in the entries are very limited. In addition, there are not enough explanations, patterns, or examples to illustrate the correct usage of a word. Last but least, constant use of this study aid make people too much attached to the dictionary andbecome lazy, which will lead them to form a passive and lazy attitude towards learning.

　　As far as I am concerned, we should use it properly and should have a good English dictionary at hand and treat the electronic one as a makeshift（权宜之计）, when necessary.

　　 Internet and Our Life

Internet is now one of the best forms of media，with its swiftness and interactivity．Internet is becoming the foundation of our modem society．

With the assistance of Internet，more people can now communicate with one another more freely and quickly．Internet also serves to be a great source of wisdom and creation．It is already becoming the electronic library of the future，giving vent to creativity and ingenuity unparalleled in human history．But Internet is a double-bladed sword．Its ability to distribute information and connect people around the world is often abused by us．Junk mail proliferates the Internet．Every year，many young people are deceived  by their online friends The damage we have suffered from Internet is also too revere to recover．

Indeed，Internet access connects many of us to a world of information at the touch of a button．Internet is such an integral part of our life．In order to have Internet serve us human-beings well，we must not take its negative sides for granted．Web sites，especially the web sites available to the young children，must be strictly censored．It is time we took effective measures to minimize the side effects of Internet．

　　 Cell  Phones

Nowadays，with the rapid development of IT and information industry，cell phones play

a dominant role in people’s life．But，like everything else，they have both favorable and unfavorable aspects．

On the one hand，the mobile phone is portable and convenient．Being wireless，you can carry them everywhere with great ease．You can reach a person wherever and however far away he is．On the other hand，it is a Mend indeed．Whenever you come across trouble，you can call for help immediately．

However，just as every coin has two sides，the cell phone also has its many disadvantages．Some people complain that mobile phones give unpleasant noise on some important occasions when the owner forgets to turn them off．And it also cuts into people’s spare time，because with the mobile phone the boss can easily reach them and call them to duty during their spare time．Worst of all，the electromagnetic wave emitted from the phone is said to be harmful to people’s health and does often cause headaches to the owner．  

In my opinion，with its expenses greatly reduced and China’s entry into WTO，the cell phone，will face an even brighter future in its development．They have changed the way we communicate an．d have made our life more convenient，and thus will stay in people’s life．
