I saidI hope to visit Paris again.2.动词不定式的进展式：表示与主动词同时发生且动作正在进展。eg:The two cheats pretented to be working hard.3.动词不定式的完成式：表示不定式动作发生于主动词之前。eg:She seems to have seen this film.He happened to have gone out when I went to see him4.动词不定式的被动式：表示与逻辑主语之间的被动关系。eg:The meeting to be held tomorrow is about how to stop the pollution.I want to have been told the news earlier.动词不定式的句法功能不定式的句法功能是做主语，表语，宾语，宾语补足语，主语补足语，定语，目的状语和结果状语，分别给出一个例句：1 To master a foreign language is necessary for a college student.(主语)2 Your job is to wash dishes.表语3 She promised to give him a
