　　答案

　　1.【答案】B。解析：考查强调句。It was/is…that…,为强调句基本结构，特点为去掉此结构后句子仍然完整。故选B。

　　2.【答案】B。解析：考查强调句。强调句结构：It was +被强调部分+that/who+其他，判断是不是强调句，it was that去掉，整个句子不缺成分，意思完整;题目强调时间状语从句when....playground。故选B。

　　3.【答案】A。解析：考查强调句。强调句一般疑问句的结构为：Was/Is it+被强调部分+that+剩余部分?故选A。

　　4.【答案】C。解析：考查强调句型和定语从句。It is/was... that是强调句型，去掉后不影响句意;可以强调除谓语外的任何成分。从句produced TV sets缺少主语，所以排除关系副词，排除D;第二空是强调句的that部分，所以排除A、B。故选C。

　　5.【答案】C。解析：考查强调句。被强调部分是at nine o'clock。判断强调句和时间状语从句的区别就是去掉it is/was...that观察原句子是否完整，若完整则为强调句，该题明显符合。故选C。
