●She pretends that she will be helped with her work. (宾语从句动词使用被动语态的一般将来时)
= She pretends to be helped with her work. 她假装有人要帮助她干活。
不定式一般式被动式"to be helped with her work”表示将来被动, 相当于that she will be helped with her work
●She pretends that she has been helped with her work. (宾语从句动词使用被动语态的现在完成时)
= She pretends to have been helped with her work.
她假装她的工作是在别人帮助下完成的。
不定式完成被动式"to have been helped with her work”表示过去被动，相当于that she has been helped with her work.
2) 我们再以不及物动词 seem，appear, happen为例进行分析
● It seems that Sharon is a brave girl.
= Sharon seems to be a brave girl. 莎朗似乎是个勇敢的女孩。
seem 是不及物动词，that引导的从句担当主语，it是形式主语。当句子以简单句形式出现时，从句的主语担当主语，seem, appear, happen后面的非谓语动词只允许使用动词不定式的各种形式担当表语, 而不可以使用动名词。
● It happened that Harrison was sleeping in the room.
= Harrison happened to be sleeping in the room.
碰巧当时哈里森正在屋里睡觉。
不定式to be sleeping担当不及物动词happened的表语，源自was sleeping。
* 不可以说：Harrison happened ╳sleeping in the room.
不及物动词happened不可以跟动名词sleeping担当表语。
