英语语法高手进
我搞了几个句子 尤其是语法方面 我要用来写作文的
第一句：Believe it or not,look around yourself and you can,I bet,easily find that digital products have found their way into our daily life.As a result,never before has so much controversy been aroused concerning these high-tech products,ranging from computers to Mp4s.
第二句：Of the millions who saw Haley’s comet in 1986,how many people will live long enough to see it return in the twenty-first century.这句如果是对的话 主语应该是how many people吧
第三句：Long before children are able to speak or understand a language,they communicate through facial expressions and by making noises.这句是原句 只是我比较奇怪两个分句之间是否要加连词and,难道因为前面有Long before 就可以不加了么
暂时就这么多了
