你说的是这两个句式的用法吧?这两种说法都对,但第一个更地道,所以在很多地方能见到类似的句子. I think it +adj.+ to do sth(这句中的it作形式宾语,指代真正的宾语to do sth) I think it is +adj.+ to do sth(这句中it is +adj.+ to do sth是由that引导的宾语从句,但that被省略了.it在从句中作形式主语,指代真正的主语to do sth) 你的句子并没有写完整,我给你举个例子吧 I think it important for the students to learn English well.我认为学生学好英语很重要.(这句绝对是地道的英语比I think it is important for the students to learn English well. 要好得多.)
