Question

find it+adj+to do对么

Answer 1

1 It is important to drink enough water every day.
it形式主语，没有意思的，to drink enough water every day真正主语，意思是：每天喝足够的水很重要。你看，主语那么长，而谓语就is important 那么短，是不是头重脚轻啊，为了句子平衡，使用了形式主语，而把真正主语放在后面，所以句型：it‘s+adj+to do 的意思是：做某事怎么样。
2 Doctors think it is important to drink enough water every day.
这时候It is important to drink enough water every day.
是宾语从句，作think的宾语。因为think 可以形成think+ 宾语+宾语补足语，所以此句可改成Doctors think it important to drink enough water every day.
也就是少了be动词is.此时，it是形式宾语
important为宾语补足语to drink enough water every day为真正宾语。
能这样用的，除了find外，常见的还有：find,believe等
