Step 2 Grammar learning
1．不定式的被动形式
当不定式与逻辑主语之间是被动关系时，即不定式的逻辑主语是不定式所表示动作的承受者，不定式一般要用被动形式。其被动式可以分为两种：一般式和完成式。
(1)一般式：t be dne，表示不定式动作在谓语动词之后或者同时发生。
It is a great hnr_t_be_invited_t speak here. 很荣幸被邀请在这里讲话。
The nvel is said_t_be_published_next mnth. 据说这本小说下月要出版。
(2)完成式：t have been dne，表示不定式动作发生在谓语动词之前。
The bk is said t_have_been_translated_int six languages. 这本书据说已经被翻译成六种语言。
The bss preferred_t_have_been_given_mre wrk t d.
老板宁愿被分给更多的工作做。
2.不定式被动形式的作用
(1)作主语
It's an hnr t_be_invited t the ceremny. 很荣幸被邀请赴宴。
It's a pity t_be_kept in the huse in such fine weather. 在这样好的天气被关在家里真是遗憾。
(2)作表语
The letter is_t_be_sent_by airmail. 这封信笺要空邮。
(3)作宾语
She didn't like t_be_treated as a child. 她不喜欢被当成孩子。
The by asked t_be_given an pprtunity t try again.
那男孩要求给他再试一次的机会。
(4)作宾语补足语
I'd like my bedrm t_be_cleaned. 我想整理一下我的卧室。
(5)作定语
He was the last ne_t_be_asked t speak at the meeting. 他是最后一个在会上被邀请发言的人。
(6)作状语
His mther left the small village，never_t_be_seen again. 他母亲离开了那个小山村，再也没有人见过她。
3．不定式有些要注意的地方
(1)感官动词和一些使役动词的不定式的主动形式要省去t，但在变成被动语态后需要加上t，能这样用的动词或动词词组有：make，have，let，see，hear，ntice，listen t，watch等。如：
We ften see him act like that.＝He is ften seen t act like that.
我们常常看到他那样做。
(2)在can't help but，have nthing t d but结构中，介词but后的不定式省去t。如：
I can't_help_but suspect his mtive.
我不禁怀疑起他的动机。
I have_nthing_t_d_but_watch TV.
我没什么事情可做，除了看电视。
(3)不定式有时要用主动形式表示被动意义
①形容词以及含有形容词的名词后的不定式，一般用主动形式表示被动意义，其中形容词常见的有easy，difficult，imprtant，impssible等。如：
The wrk is impssible_t_finish in tw days. 工作不可能两天之内完成。
English is nt s easy_t_learn. 英语并不好学。
②一些固定用法，如“挨骂，受责备，受批评” 用be t blame；“(东西等)出租”用t let。
He is t blame fr what he has dne.
他应为他所做的受责备。 The huse is t let.房子要出租。
