A that B which C when D where

The boy found himself in a situation ___ it was hard to make a choice,so he asked his parents for advice.A that B which C when D where
D where
situation之后的定语从句用where

选B where ,引导定语从句,从定语从句的结构来看,定语从句不缺主语和宾语,引导词where在从句中充当的是状语。那么为什么不用which呢,什么时候用which什么时候用where。

句中的先行词是situations,表示“情形,情况”,引导词依然用的是where,表示“在这种情况之下”。这里的定语从句也是不缺主语或宾语的,where在从句中充当的是状语。

选B where ,引导定语从句,从定语从句的结构来看,定语从句不缺主语和宾语,引导词where在从句中充当的是状语。那么为什么不用which呢,什么时候用which什么时候用where。

句中的先行词是situations,表示“情形,情况”,引导词依然用的是where,表示“在这种情况之下”。这里的定语从句也是不缺主语或宾语的,where在从句中充当的是状语。

如何判断是否使用where来引导定语从句了。此外,我们需要仔细体会例句中where指代先行词时所表达的含义,分别是“在……样的语言中”“在……中”“在……样的状态下”,这些含义都带有抽象的地点意义。因而,我们在日后的学习和考试中应当谨记:
用where引导的定语从句,先行词不一定是表示地点的名词,因为先行词也可能是含有抽象地点意义的名词。由此,我们总结如下:
先行词是表示“地点”或任何含有“抽象地点意义”的名词用where引导定语从句
例子:

1.Remember that the best relationship is one where your love for each other is greater than your need for each other.
请记住,最深的感情关系表现为彼此间的爱超过彼此间的需要。
点评:这里where引导的定语从句修饰先行词one,也就是relationship (此处one指代的是relationship)。Relationship不是地点名词,但此处却用了where来引导,where在这里表示“在这样的感情关系下”。从定语从句的结构来看,定语从句不缺主语和宾语,引导词where在从句中充当的是状语。
2. Cheating is most likely in situations where the vital interests are high and the chances of getting caught are low. 欺诈行为在这种情况下最有可能发生:利益重大,而且欺诈行为被发现的可能性小。
点评:句中的先行词是situations,表示“情形,情况”,引导词依然用的是where,表示“在这种情况之下”。这里的定语从句也是不缺主语或宾语的,where在从句中充当的是状语。

3. Until such time as mankind has the sense to lower its population to the point where the planet can provide a comfortable support for all, peoplewill have to accept more “unnatural food”.除非人类能够意识到要把人口减少到这样的程度——使地球能为所有人提供足够的食物,否则人们将不得不接受更多的“人造食品”。
点评:这里的先行词是point,表示“某种程度,某种状况”,引导词where指代point,表示“在这种程度下”。这里定语从句也是不缺主语和宾语的,where在从句中充当的仍然是状语。
从上面三个例句中,我们可以发现以下两点:第一,即使先行词不是表示地点的词,定语从句也能够使用关系副词where来引导;第二,上面三个例句中,
where分别指代relationship、situation和point,分别表示“在……关系中”“在……情况下”“达到……程度”,这些词虽然不是表示地点的名词,但在从句中表达的是“某个点或状态”的含义。我们可以把这类名词解释成“含有抽象地点意义的名词”,此类词也能用关系副词where来进行引导。
先行词不表示地点时,如何判断是否使用Where引导定语从句当先行词不是表示地点的名词时,该如何判断是否使用where引导定语从句呢?由上文给出的例句可知,含有抽象地点意义的名词能用关系副词where来引导,并且在每个例句的点评中都反复强调“定语从句不缺主语和宾语,where在从句中充当的是状语”。
