2) 要不要 it的问题:
先看两个句子:
We sometimes find it difficult to get rid of a bad habit. 该句的原始结构可理解为:We sometimes find difficult. 括号部分为宾语,difficult为宾语补足语
The doctor has made it clear to you that there is nothing wrong with your stomach.该句的原始结构可理解为:The doctor has made clear. 括号部分为宾语,clear为宾语补足语
归纳:
n 在主语 + 宾语 + 宾语补足语结构中,当宾语是动词不定式或句子时,要用it作形式宾语,将动词不定式或句子移到句子的后面去。
n 考试时,判断要不要 it,主要看句子后面有没有动词不定式或句子,若有,要选 it
n 宾语、宾语补足语倒装:当宾语较长,宾语补足语较短时,为了句子结构均衡,往往采用倒装,这里不存在it的使用问题, 对下句作出判断:
The development of ultrasound has made ______ early diagnosis of some fatal diseases.
A. it possible
B. possible
C. it is
D. it
该题的正确答案应为B,因为句子采用了倒装形式,原结构为:
The development of ultrasound has made possible.
