高一英语第二单元中If you’ll excuse me now.这个句子对吗？人教版 当if 引导表示将来概念的条件状语从句时，通常不会出现will，而是用一般现在时或者现在完成时。否则，句子就会被视为是错句。 但在人教版高中英语第一册上第8页中却出现了这样一个句子：If you’ll excuse me now.这是否意味着教材出错了呢？答案显然是否定的，因为will在下列情况下就可以用于if状语从句。 一、当will 用作情态动词表示客气请求时 1．Now if you will take off your clothes, Emperor, we will fit the new suit on you in front of the mirror. 2．If you will kindly wait a moment, I’ll be with you in a minute. 二、当will 意为“be willing to”时 1. If you will just sign here please, I’ll give you the money. 2. If you will take the trouble to read this letter carefully, you will see what he means. 三、will表示决心、坚持或允诺时 1. If you will eat too much pastry, you can’t complain if you get fat. 2. If you will go, you may go at once. 四、如果if 条件状语从句指的是主句动作的结果时，可以用will. 1. If it will make you happier, I’ll stop smoking. 2. I’m willing to lend you $ 10000 if it will enable you to own that flat. 本文来源：https://www.wddqw.com/doc/720a59d70b75f46527d3240c844769eae009a38a.html
