In this sense, cell phones can provide an effective way to get information timely, since they are becoming more and more advanced.

眾所周知，在21 世紀最有價值的東西就是信息。因此，獲取最新信息對于每個人來說都是十分重要的。從這個角度來講，日益先進的手機能夠為我們及時獲取信息提供一種十分有效地方式。擁有一部手機，我們可以發電子郵件，瀏覽網頁，從而對于外部信息可以了如指掌。因此，我認為手機是現代大學生的必需品。

Cell phone are oot necessary for college students.

手機并不是大學生的必備品。

Nowadays, cell phones are owned by more and more college students. But for most of them , the most important usage of cell phone is to send messages. To some extent , it ’s just a kind of entertainment for them, rather than a necessity.

如今，越來越多的大學生擁有手機。而對于他們中的大多數來說，手機最重要的用途是發短信。從某種程度上講，手機成為了他們的一種娛樂工具，而非生活的必需品。

Besides, cell phones can waste a lot of time. Many students send messages to each other rather frequently , becoming the so called "clan of thumb culture" ( 拇指一族). As a result, their talking are time-consuming and inefficient. Therefor, I think cell phones are not necessary for college students.

另外，手機浪費了大量的時間。許多學生因太過頻繁的發送短信而變成了所謂的“拇指一族”，而他們的談話其實是瑯費時間，毫無效率。因此，手機對于大學生來講并非必需品。
