It is +adj doing 什么时候用?It is +adj to do什么时候用? it is + adj.+of/for sb.+to +doing?to是介词吗?介词后加doing? it is adj + doing or to do?会的请帮解答Q1.It is useful/useless/nice/good/interesting/expensive (to do / doing?)这种的it is 加 adj 後面的到底用哪种正确?似乎网上也很多人搞不太清楚有些说只能用 to do sth有些说只 老师问一下,it is +名词+doing对吗it is +adj.+to do和+doing有什么区别? it is+adj+从句 it's adj+to do还是doing? it is no good doing 可以用 to do 代替doing 为什么?平时最熟悉的是it is +adj + to do it作形式主语的问题it's +adj+to do sth是否等于it's+adj+doing sth例如it's wrong to do sth是不是可以说成it's wrong doing sth?如果不能,那么it's+adj+to do sth除了to do sth +is + adj有同义句吗?“动词不定式作主语 it is my frist time to do sth / or doing sth/or do sth? 请教it is no use doing我觉得好乱啊!it is no use doing sth , 但是it is adj + to do ,这叫什么事啊?为什么不能说it is no use to do 呢? “It's + adj.+ to do 不定式”与“It's + adj.+ doing sth.”的区别 类似于it is no use doing,是不是只要it is 后面加的是n.而不是adj.后面就是加动名词的? what is it doing what is it doing it is about doing how is it doing it isn't easy being the new kids at school.为什么用being而不是to beit is +adj+to do sth这里用这样不是说可以 it is +adj+doing sth
