B. how did the living things come into being
C. of how the living things come into being

为什么选C不选A?

Answer 1

1. 是定语从句，其中all是先行词，that为引导词。此处并非是非限制性定语从句，因为非限制性定语从句是指先行词与引导词之间有逗号。
2. 警察确定凶手就是那个人，他的枪被发现就在死者身旁。
3. C 此处all the food是先行词，引导词that在定语从句we eat中作eat的宾语，故可以把that省略。剩下了we eat。

追问

后三题呢？

追答

后三题：1. C 不选B，因为当定语从句先行词有such修饰时，定语从句引导词必须用as，as在从句中作主语；而such...that结构中的that是不作任何成分（that引导的是状语从句）.
2. A that在定语从句中作spent的宾语。when是副词，不能在从句中作宾语，故被排除。
3. C 一个从句只能有一个引导词，而A中有两个引导词，即that和how，故排除A；而C则可以，of后接的how引导的宾语从句（用陈述句语序）。

追问

第二题为什么不选C?
第三题how是引导词？这不是定语从句吗？

追答

2. 第二题不选C，因为“介词+which”的作用相当于when等副词，也是不能充当从句中spent的宾语。
3. 第三题中的how引导的从句是介词of后的宾语从句，并不是定语从句。

Answer 2

我同意上面两位高人的看法。
类似于这道的选择题我见过，选项是only
that,all
what,all
that,only
that
选项应该是all
that，因为主句缺主语，all作主语，that
I
need
是一个由that引导的定语从句，先行词是不定代词all。

Answer 3

1. all that=what，此处引导主语从句，不定式做目的状语

2. 警察确定尸体旁的枪就是凶手的。

3. C 几乎所有我们的食物都来源于动物和植物。  Nearly all the food （that）we eat、、、that引导定语从句在句中做宾语成分，被省略。

Answer 4

这句不是非限制性定语从句，是一般的句子，all that=what
警察确定凶手的枪是被发现躺在尸体的旁边。
几乎所有的食物来自动植物。food不可数且是用that引导的定语从句三单
