I agree the author’s thought. From now on, many people use computer with internet to talk. That’s really convenient, if I see this paragraph, I might steal want to use the Net. Why it is not good? That because we can forget a lot of words. We do not correct the correct words. After several months or years, we can forget almost 20 percent of words we have learned. So net is convenient but there are some dark and horrible things behind it.
