【诵读·积累】
(2010·安徽高考)假设你将参加某英语杂志社开展的一次征文活动, 征文的内容要求你在电视、手机(cell)和网络三者中, 放弃其中一个并陈述理由。请你以“Which would you give up: TV, cell, or Web? ”为题, 写一篇英语短文。
写作要点:1. 电视、手机和网络的普及;2. 自己的选择;3. 陈述理由。
Which would you give up: TV, cell, or Web?
①We are now living in an information age, in which TV, cells and the Web are widely used. ②It seems that many people cannot 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. ③I 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. I need a cell to keep in touch with my friends and family, and almost all information can be gathered on the Internet.
