I would appreciate if与I would appreciate it if辨析

问题描述

底下是TOEIC 全真试题的摘录:

I would appreciate if you would set aside the whole day on March 3 so that I can meet with you.

这里的 appreciate 是及物动词，为何不用加 it? 谢谢！

老师答疑

陈老师：

有人认为 I would appreciate if…或 I would appreciate it if…都可以用，但在现代英语中通常是有 it 的，即这类句式中的 it 通常不宜省略。

比如《葛传椝英语惯用法词典》就认为：

I shall appreciate it if you will give me his address 里的 it 最好不要省去。

注：该词典认为“it 最好不要省去”，那言外之意就是，省略 it 也不是完全不可以。

但《剑桥高级英语词典》则认为：

Common mistake : would appreciate

Remember: “would appreciate” is usually followed by “it”. Don’t say “I would appreciate if...”, say “I would appreciate it if...”:

I would appreciate if you could pick me up from the airport.

所以，我觉得你的句子要么就是引文有误（即TOEIC的原题可能是有 it 的，但引用它的人把 it 给漏了），要么它就是使用了一种不常用的用法。所以，给你的建议是：自己在使用这类用法是最好加上这个 it。

黎老师：

《牛津英语用法指南》第三版447.3节指出：在 would appreciate 之后，it 用作 if 从句的先行宾语。I would appreciate it if you would keep me informed .如能随时告知情况，我将非常感激。（不能说：I would appreciate if you would ...）

所以，你的问题中的 I would appreciate if…应该改为 I would appreciate it if…
