Module 4 Seeing the doctor重点语法讲练（含答案）2024-2025学年外研版八年级英语下册

Module 4重点语法讲练 2024-2025学年外研版八年级英语下册 现在完成时(3)语法讲解与练习 一、现在完成时与for/since连用 现在完成时表示某一行为或状态从过去某时开始，一直持续到现在，可能刚刚结束，也可能继续下去。 - for + 时间段：表示动作持续的时间长度 - since + 时间点/从句：表示动作开始的具体时间 例句： 1. Jim has studied Chinese for five years. 吉姆学习汉语五年了。 2. They have worked here since three years ago. 他们自从三年前就在这里工作。 3. I have taught English since I came to this school. 自从我来到这所学校，我就教英语。 注意： 1. for后接时间段，since后接过去的时间点或从句 2. 对for或since引导的时间状语提问用how long 二、非延续性动词的用法 英语中有些动词表示的动作不能延续，被称为非延续性动词。在现在完成时中： 1. 不能与表示一段时间的状语连用（否定句除外） 2. 若要与时间段连用，需要： - 用"be+形容词/副词"或"be+介词短语"替换 - 用对应的延续性动词或短语替换 常用转换： | 非延续性动词 | 延续性表达 | | begin/start | be on | | go there | be there | | come back | be back | | open | be open | | die | be dead | | finish | be over | | leave | be away | | borrow | keep | | buy | have | | put on | wear | 助记口诀： 非延续性动词不能延，肯定句中不延时间段； be加形/副把位占，keep，have常顶班。 练习题 一、用for或since填空 1.
