基本信息
to see one time is better than to hear a hundred times. to persevere means victory! 注①：在很多情况下，特别是在口语中，常采用先行it代替主语，而把不定式后置： it’s a great pleasure to be here. it is not an easy thing to master a language. 注②：这种后置不定式的结构也适用于某些谓语动词不是系动词的句子，如： it took us five hours to get there. it made us very angry to hear him talk like that.
