强调句和定语从句的区分

各位小伙伴，先看看下面的两组句子。。。 A (1) It was last year when you taught me how to drive. (2) It was last year that you taught me how to drive. 这两句有一句是错误的，你发现了吗？如果找到了， 那么你就掌握这个知识点了》》》 开讲了!!! A组中的(1)句是错误的。因为之前讲过when=in which 没有in last year，这个短语。（2）句是强调时间状语 B (1)It is on the island that they spent 10 years. (2)It is the island where they spent 10years. B组 第一句是强调句，强调地点状语on the island 第二句是定语从句，先行词为the island 方法 把It is/was........that......去掉后句子意思、结构完整则是强调句； 如果去掉It is/was .....引导词.....后成分短缺为定语从句。
