中高考语法：不定式的被动语态To be done／to have been do
不定式的被动语态在初中阶段有所涉及；高中阶段在人教版选修性必修四的附录附有语法讲解。但内容不多。
此种结构不难；但如果搞不清句子的结构（主动还是被动），会是理解文章、高考考试的一障碍。
本文对此种结构进行分析。
一 、一般情况基本结构 to be done
不定式to do sth ,如果有表示被动，则要用不定式的被动语态， 即 to be done的结构。
构成由来： 1. 被动语态的基本结构 be+ done(done指的是动词的过去分词) +2. 不定式to do sth
在一般不定式的被动语态基本结构 to be done中， 这时不定式to do sth 中的 do （泛指任何动词）变成be（被动语态的基本结构中 be+ done的be）；表示被动，+ done(动词的过去分词) 。因此，结构为： to be done（的结构）
例如：It`s important for the figures to be updated regularly.
figure数据 和update（更新） 间有被动关系，数据是被更新。此句的主动结构是：
It is adj(形容词) for sb to do sth. 可以是： It`s important for us to update the figures regularly.变成被动，即是： It`s important for the figures to be updated regularly.
详见 中高考句型 It is adj(形容词) for/ of sb to do sth详细分析
再如：
It is not unusual for teenagers of your generation to be attracted to computer games and the online world. (人教版高中英语必修一 unit 1 Teenage Life )
二、 不定式的完成时的被动语态 to have been done
：：to be done(一般被动)+ have done sth (完成时)= to have been done；不定式的完成时的被动语态。
注：比较少见。
理解: 表示（不定式do）动作发生在 谓语动作之前，且是被动。例句:
I`m honored to have been given the chance to stand here and let my voice heard by all.---given the chance (被动)动作在stand here（及后面动作）前
三、 使用情况，举例分析（句子中，如果是主动语态，使用的短语或句子结构） （参考 英语中to 的常见意思及用法详解）
1 I wish to be sent to work in the western region. （人教版选修性必修四 附录 语法 例句） Wish to do 的结构
2 It's a great honour for me to be invited to Mary's birthday party. （人教版选修性必修四 附录 语法 例句）
It is n (for sb) to do sth 的结构 （详见 中高考句型 It is adj(形容词) for/ of sb to do sth详细分析
3 The progress to be made soon is of great importance. 不定式作定语： to be made 作为progress定语，翻译为“要被制作/完成的”
4 The meeting is to be held next Sunday. be(am, is ,are ) to do 表示将来的意思。作表语
四、思考：教材、高考链接（试着判断，句子中，如果是主动语态，使用的主动语态的短语或句子结构）：
1 Additionally, from time to time I will assign group work to be completed in class or short assignments to be completed at home, both of which will be graded. （2022高考全国卷I）
2 She immediately became the first woman ever to be hired as a resident physician in the OB-GYN department of the PUMC Hospital. (She immediately became the first woman ever to be hired as a resident physician in the OB-GYN department of the PUMC Hospital. (人教版高中英语必修三 unit 2 morals and virtues )
