考点5. 名词性从句是复合句时,不要忘了带that (双连接词)
改错:
① The question was that whether he could get a job at the center.
② You have no idea that how busy we were those days.
③ It is well known what a person eats causes changes in the body.
答案及解析:
①去掉that,。后面whether本身就起着连接作用。
②去掉that。 who, how, when, what等本身就有两个作用:作从句的成分;起连接作用。
③在what前面加that。what只是把主语从句的两个分句连接起来,但其作为一个整体来作主语从句时还需要用that引导。
