ugust Wilson's Pittsburgh Cycle consists of ten plays,nine of which are set in Pittsburgh's Hill District,an African American neighborhood,and each of which is set in a different decade of the twentieth century.
分析一下这句话的句子结构就不难看出其它选项的错误:这是一个并列复合句,主句是
August Wilson's Pittsburgh Cycle consists of ten plays ,后面由 and 连接两个并列的由 which 引导的定语从句表示“比赛”的时间和地点,先行词(被修饰语)都是 “plays”,B、C 、D 答案中 them 不能起到引导从句的作用.如果将 plays 后面的逗号改为句号,则 B 答案成立,但 are 必须改为 is.E答案中最明显的错误是“ and each have(应该是 has)”,当然还有其它问题.
不能谈的太多,如仍有疑问,欢迎追问探讨!
