问题描述：
John's success has nothing to do with good luck.It is years of hard work__has made him what he is
打不开了后面是today.选项A why B when C which D that为什么不选C呢而选D呢能不能分析一下
答
强调句型 ：It is + 被强调部分+ that + 其他
这里强调的是years of hard work
答
选C,
因为这是一个强调句,
强调句的固定句型是It is …+that从句,
要判断一个句子是强调句,只要看它去掉了It is和that后句子能否仍然成立.
若成立,则是强调句
