He wants to tell the children ________________________________.
A.how important it is to protect our environment
B.how important to protect our environment
C.how important is to protect our environment
A.how important it is to protect our environment
B.how important to protect our environment
C.how important is to protect our environment
A,it 是形式主语，不能省略，后面的 to ......才是真正的主语，
He wants to tell the children ________________________________.
A.how important it is to protect our environment
B.how important to protect our environment
C.how important is to protect our environment
应该选A
从整体上来讲,这个句子可分为三个部分
第一部分是He wants to tell the children
意思是说他想要告诉孩子们
第二部分是how important it is
want to后面是从句,疑问句应改成陈述句语气,所以是
how important it is
第三部分是to protect our environment
是用来修饰形式主语it的
所以这道题目的答案是A
A.(tell sb. to do sth. 然后本句要用陈述语气,所以是it is)
选A
how+adj+it is!
表感叹吧！
B
important+to+句子
A,it 是形式主语，不能省略，后面的 to ......才是真正的主语
