关于英语从句的题目解析
A recent study showed how the temperature,______ water freezes,can be changed using electric charges．
\x05A．at which \x05B．for which \x05C．in which \x05D．with which
A．at which \x05B．for which \x05C．in which \x05D．with which
为什么?请问整句话怎么解释?

"the temperature,______water freezes"的意思是水结冰的温度,横线部分可以用"when"来代替,如果用"介词+which“的形式,关键是看与先行词"the temperature"搭配的介词什么,这里"at the temperature"是习惯性用法,因此选A.
一般来说,做定语从句最简单的方法是将答案带入从句进行检验,这里定语从句的从句部分即是"water freezes at the temperature",for、in 和 with明显是不对的.
