　　答案

　　1.【答案】B。解析：考查強調(diào)句。It was/is…that…,為強調(diào)句基本結(jié)構(gòu)，特點為去掉此結(jié)構(gòu)后句子仍然完整。故選B。

　　2.【答案】B。解析：考查強調(diào)句。強調(diào)句結(jié)構(gòu)：It was +被強調(diào)部分+that/who+其他，判斷是不是強調(diào)句，it was that去掉，整個句子不缺成分，意思完整;題目強調(diào)時間狀語從句when....playground。故選B。

　　3.【答案】A。解析：考查強調(diào)句。強調(diào)句一般疑問句的結(jié)構(gòu)為：Was/Is it+被強調(diào)部分+that+剩余部分?故選A。

　　4.【答案】C。解析：考查強調(diào)句型和定語從句。It is/was... that是強調(diào)句型，去掉后不影響句意;可以強調(diào)除謂語外的任何成分。從句produced TV sets缺少主語，所以排除關(guān)系副詞，排除D;第二空是強調(diào)句的that部分，所以排除A、B。故選C。

　　5.【答案】C。解析：考查強調(diào)句。被強調(diào)部分是at nine o'clock。判斷強調(diào)句和時間狀語從句的區(qū)別就是去掉it is/was...that觀察原句子是否完整，若完整則為強調(diào)句，該題明顯符合。故選C。
