I'll get it for you _I could remember who last borrowed it A if only B on condition that

问题描述:

I'll get it for you _I could remember who last borrowed it A if only B on condition that
请详解,说明到底选哪个以及另一个错误的原因

I'll get it for you _I could remember who last borrowed it A if only B on condition that
选B 解释为 如果
翻译
我会帮你拿到它如果我记得谁借走了
A 【if only】解释为要是...就好了
意思不对
有不会的可以再问我我也觉得选B,可是答案给的是A,解释的是A后面接虚拟语气。if only有个“只要”的意思吧,也说得通,只是我不知道B哪里错了。。嗯~看来因该是A因为【on condition that】=【if】要用主将从现这边后面用的是一般过去时,表示对将来的虚拟,所以不能选B
