1.the average number of hours that an American’s person spends on TV is 5, 好像直接说average time of xxx is 5 hours 更好吧,虽说字数重要,但你那样写冗繁了.
2.what is worse, five of which must be with television,这里的后面这句用的不对,which指代什么呢?句子前面没有24小时啊,个人以为不妥
3The most frequent topics people now talk with each other are always from television shows, talk with是不是该用talk about with?
4And unfortunately, the topics always have nothing to do with the technology, the culture, the education field, instead, the scandal of a movie star, the complex and bored plot of soap opera occupies the talking.这个句子是不是太长了,而且里头连贯性不是很好,我觉得切成两个句子挺好的,而且这个用来证明你的观点太牵强了,个人以为不好.
小可水平不高,可能所说的也有错误,楼主自己斟酌,祝楼主考试顺利
