I find it easy to get on with her. 我发现她很容易相处。

例:______________________________________.(他感到在学习上集中注意力很难。)【注意】由于介词后通常不能直接跟that从句作宾语,有个别特殊结构就在介词后先接it 作形式宾语,再跟that从句(主要有enjoy, like, dislike, love, hate, prefer, appreciate等表示情绪的动词),如:

It is April First today. // It is some 3000 kilometers from A to B.
