[精美语篇]
We are now living in an information age, in which TV, cells and the Web are widely used. It seems that many people can't enjoy themselves without them.
However, if I had to give up one of them, I would turn off the TV rather than switch off my cell or cut off the Internet. I could do without TV because few shows take my fancy and there're too many commercials. Besides, most programs on TV are also available elsewhere.
As for cells and the Web, they are more necessary to me because a cell can make me keep in touch with my friends and family while the Internet can provide me with almost all information.
高频单词
1．assist (vt.) 帮助；协助→assistance (n.) 帮助；协助→assistant (n.) 助手；助理。
