this is what we call a chain reaction还是this is what is we call it a chain reaction?
问题描述:
this is what we call a chain reaction还是this is what is we call it a chain reaction?
答
前者.
在句子中,有两个谓语,就有一个连接词;有三个谓语,就有两个连接词.
这里is、call都是谓语,所以有一个连接词what,如果再多一个is,则缺连接词了.
其实what we call a chain reaction是一个表语从句,作系动词is的表语.句子意思是“这就是我们所说的连锁反应”.
