英语语法问题

These books are for you____
A, to choose B, to choose out C, to choose from
求语法详细分析
尤其是不定式主被动问题麻烦配合例句讲解
答: C
译：这些书是供你（从中）挑选用的。
这题用来分析不定式的主被动不妥。此题也没有被动不定式选项，主要考查choose sth. 与choose from sth.的区别。
如问不定式作定语的情况，则应记住：其逻辑主语就是被它所修饰的名词，跟据这个名词和这个不定式动词之间的关系决定用主动还是被动：The years to come =The years that are to come, 用主动。 The house to be built next year= the house which is to be built next year 用被动。
但是要注意这两种句型：
Sb. have sth. to do.
give sb. sth. to do
虽然sth. 是被do, 但sb. 与 do之间有逻辑上的主谓关系,所以仍用主动不定式。如：I have some clothes to wash. 是我洗衣服。如果不是我洗，还是得用被动不定式：I have some clothes to be washed. ( by others). 我有一些衣服要拿去洗。
另外there be句型，两种都可以，区别不太大。
There is sth. to do / to be done.

C you can choose from these books 不定式修饰book 你想那个句子 the question is hard (for you) to answer. 不需要被动，因为有逻辑主语you
被动是这样的：there is much to be done (by us)
秘书问经理： do you have anything to be typed (by me)? 强调被别人 ，不是听话的对象
秘书说自己：i have something to type

选C. choose from表示从……中选取。choose+名词表示选择什么
不定式作定语表示尚未发生的动作，如: I have some books for you to read.
Give me a piece of paper to write on.
以上都表示主动关系。

C.
