Question

高中英语，定语从句

The schools themselves admit that not all children will be successful in the job__ they are being trained.
A in which B for which
为何选B不选C

Answer 1

答案：B.

翻译：学校自己也承认，不是所有的孩子都会在他们为之而正在接受培训/训练的工作/职业中成功。

解释：
1. 定语从句如果使用关系代词，必须记住关系代词等同于先行词，并在定语从句中充当一定的成分。
2. 此题中，which = the job，做介词for的宾语，代入定语从句中为：
for which they are being trained
= they are being trained for which
= they are being trained for the job
句意为：他们正在为了这份职业而被培训/训练
3. 如果使用in which，则定语从句为：
in which they are being trained
= they are being trained in which
= they are being trained in the job
句意为：他们正在工作中被培训/训练
4. 两相比较，肯定是for which更符合句意。

Answer 2

不知道C选项是什么。不过train for sth.这个短语的意思是为某事而进行的培训。

这句话的翻译就是：校方承认，在接受此项工作培训的孩子当中，不是所有的人都能有所成就。

希望可以帮到你！

Answer 3

trian sb for 为。。。而培养/培训/训练某人 是固定的搭配 因此在要用B
