答案选C
He __doesn't know why she came .
主句谓语是现在时 宾语从句可以根据情况 用 不同的时态
选项A B 错 因为 不符合 主句谓语是过去时 宾语从句也必须是过去时 这一原则
选项D 第二空 错
2 答案选C It's quite a small room.注意quite和very的用法 就行了
quite a small room= a very small room

第一题根据时态来选择，“他不知道”是一般现在式，“她为什么...”是一般过去式，所以选C
第二题quite是一个修饰程度的词，有固定用法 quite a ....,如果要选very的话应改为 a very

第一题
时态的包含性。后一空是描述已经发生的事情，时态不能早于前一空。D合乎语法但语意不合常理（he是个智障才可能发生）

第二题
表示“这是一个相当xx的yy”，用“it's quite a xx yy”。
much不能直接修饰small
very a更是胡扯

首先看从句，问原因，问她为什么做了某事，肯定是这件事she 已经做过了，所以只能是动词的过去式，排除A.B.D He 不知道原因，可以是过去不知道也可以是现在不知道
quite a +形容词是固定搭配 其他搭配不对

首先第一句是宾语从句，“他不知道”是一个持续的动作，该用现在时，所以AB排除；“她笑”是过去的动作，要用过去式，所以选C。
第二题一看选项就知道应该是A或C，因为quite是adv,所以不能直接与形容词small直接连用，所以选C

1ABD选项的第二个答案都不是第三人称复数形式，而且AB的时态也是不符的，只有came是过去式所以选C
2quiet应放在数词前，very放在数词后，much不能修饰形容词原级

。你好。题目解答如下：
。He _____ know why she ______ 。
A. didn't , laugh ——laugh的前面是she该用三单形式。或者是过去式。故排除。
B. didn't , leave——leave也和laugh是一样的道理。
D. doesn't , cry——解释同上。
。故综合来看，答案是D。

。It's ____ small room.
这里的room解释不是房屋。而是空间。由此可推出A，B是不正确的。
room的前面修饰一般不用very。
。所以答案是C. quite a
。望采纳。

收起

第一题后面一个空一定要填第三人称单数或者是过去式，不能用动词原形，所以除了c其他都不能选。
第二题a是不对的，见c ，b没有这种搭配，much是和不可数名词搭配的，d正确的是 a very
