do的用法知识点考点复习锦囊妙计 1、do all sb.can to do sth. do what sb.can to do sth. 尽某人的所能做某事 all 后面为that 所引导的定语从句，that在从句中作宾语已被省略；can后面为避免重复省略了do; 后面的to do sth.为不定式（短语）作目的状语。all(that)sb.can(do)相当于宾语从句what sb.can(do)。 ①I’ll do all I can to help you.我将尽力帮助你。 ②He did all he could to improve his spoken English. 他尽了最大努力来提高英语口语水平。 2、Do give her my regards. 请一定代我她问好。 助动词do及其变化形式可在肯定句中用来强调动词，意为“务必；一定；的确；真的”,加强了句子的语气。 ①Do be careful! 一定要小心 ②I do like you.我真的喜欢你。 ③She does work very hard.她学习确实很努力。 ④—Why didn’t you tell him?你为什么不告诉他？ —I did tell him.我告诉他了。 3、do sb. a favourdo sb. a favour或do a favour for sb.给某人帮个忙，如果有to do sth.则常用do sb.the favour to do sth.如： ①I wonder if you can do me a favour? 我不知道你能不能帮我个忙？（没有说干何事） ②Please do me the favour to open the door, I want to go out. 麻烦你给我开一下门，我要出去。 1.
