动词不定式主动表被动的情况:
在某些情况下,虽然表示被动意思, 用的却是不定式的主动形式。常见的有下列几种情况:
一、在某些固定句型中, 动词不定式作定语, 用主动形式表被动意义。
1)have(give, show)sth. to do
在这种句型中的不定式与前边的名词有动宾关系, 又和句中另一名词或代词构成主谓关系。例如: I have a lot of things to do this afternoon. to do与things是动宾关系, 与I是主谓关系。否则, 在表示被动意义时, 仍需要被动式。试比较:
Have you anything to do this afternoon? 今天下午你有事要做吗?
(to do是由you发出的)
Have you anything to be taken to your parents? 你有要带给你父母的东西吗? (谁带不得而知)再如:
Plea get me something to read. 请给我弄点读的材料。
He'll show you the right path to take. 他会给你指出要走的正确的路。

2)It(This, That)+be+a/an+adj. + n. +to do
50个好句在这种句型中, 不定式与前面的名词有动宾关系。动词不定式可改为动词不定式复合结构。例如: This is a difficult question to answer. 这是个难答的问题。
question与to answer为动宾关系。to answer可改为 for me to answer。再如:
It is an easy ntence to translate. 这个句子很容易翻译。
3)There +be +n. +to do
在此句型中, 觉的多音字组词用来修饰主语的不定式, 可用主动式, 也可用被动式, 只是侧重点不同。用主动式作定语, 重点在人, 用被动式作定语, 重点在物。例如:
没有时间可以耽误。可译成:
There is no time to lo(to be lost). 用 to lo可看成象雄大藏经for us to lo; 用to be lost, 谁 lost time不明确。
但下述两句用主动不定式与被动不定式意义不同:
a. There is nothing to do now. (=We have nothing to do now. )现在没事干。
b. There is nothing to be done. (=We can do nothing now. )现在没办法了。
a. There is nothing to e. (男人泡妞nothing worth eing)没有东西值得看。
b. There is nothing to be en. (nothing there at all)看不见什么东西。
二、在某些“形容词+不定式”的结构中, 不定式有被动意义, 与句子主语构成动宾关系。其句型有:
1)n. +be+adj. +to do

The job is very easy to do. 这工作很容易做。
2)n. +be+too+adj. +to do
The thing is too small to e. 这东西太小看不见。
I was too excited to say a word. 我激动得连一句话也说不出。
3)n. +be +adj. +enough to do
The box is light enough to carry. 这盒子轻得可带走。
The book is cheap enough to buy. 这本书很便宜可以买。
但下列两句可用不定式的主动式, 也可用被动式:
This plant is fit to eat /to be eaten. 这种植物可以食用。
The cake is ready to eat /to be eaten. 这块饼可以吃了。
三、某些动词, 如to let, to blame (责备), to ek(寻找)用主动式表被动意义。
例如:
The hou is to let. 这房子要出租。
Who is to blame for it? 这得怪谁?
The reason is not far to ek. 这理由不难找到。
