1.a)Do you notice the boy _____the street now?(cross)
b)Did you notice the boy_____the street just now?(cross)
a填crossing,b填cross,我想知道为啥。
2.a)The doctor advised each of us_____more exercise.(take)
b)The doctor advised/suggested we_____more exercise.(take)
a填to take,b填take,我想知道为啥b填take,a和b两个句子有什么区别吗?
3.a)She was the only girl_____to go to the party yesterday.(invite)
b)One of the girls _____to the next party will be an American.(invite)
a填invited,b填to be invited,我想知道这个不定式和过去分词作定语有什么区别,我觉得a和b填哪种形式都可以。
4.就是我想知道过去分词作宾补的时候可不可以用不定式代替,比如We saw a cow tied to a big tree.可否改成We saw a cow to be tied to a big tree.又比如She found her handbag stolen.可否改成She found her handbag to be stolen.如果可以的话,那有没有特殊的情况不可以改?
问题挺多的,希望大家帮帮忙。
