Question

harry used to consider it a great joke to go into expensive cosmetic shops and make outrageous requests for goods that do not exist.请问这句里面it后面为什么没有is?

Answer 1

It 作形式宾语
用来替代作宾语的从句、动词不定式、动名词,而把真正作宾语的从句、动词不定式、动名词置于句尾.
It 作形式宾语的常见句型：
1.verb+ it+ adj./noun (for/of) to do/clause (verb=think,believe,suppose,consider,feel,make,keep…)
这句话是把it看作是a great joke(一个天大的笑话).并不是it作主语,所以不用加be动词.
