重点语法归纳
一、if 引导的条件状语从句（主将从现）
1. 基本含义：
if 意为如果，引导条件状语从句，表示如果某事发生，就会出现某种结果。
重点语法归纳
2. 时态规则
主句：一般将来时（will /won’t + 动词原形）
从句：一般现在时（表将来）
口诀：主将从现，主情从现，主祈从现
重点语法归纳
3. 结构
主将从现（最常用）
If you try hard, you will make your dream come true.
如果你努力，你会实现梦想。
主情从现（主句含情态动词 can/may/should）
If you keep trying, you can succeed.
如果你坚持尝试，你可以成功。
重点语法归纳
主祈从现（主句为祈使句）
If you are free, please come to my home.
如果你有空，请来我家。
3. 易错点
if 引导条件状语从句，不能用将来时，从句只用一般现在时。
从句可放句首或句末；放句首时，后面加逗号。
If it rains tomorrow, we will stay at home.
= We will stay at home if it rains tomorrow.
重点语法归纳
二、宾语从句 if /whether（是否）
if /whether 意为是否，用于宾语从句，常放在动词后（know, wonder, ask, tell 等）。
重点语法归纳
二、情态动词表推测（may/might/must/can’t）
2. 用法区别
一般情况，if = whether，可互换
例：I wonder if/whether he will come. 我想知道他是否会来。
只能用 whether，不能用 if 的情况
后面直接接 or not：whether…or not
例：I don’t know whether he will come or not.
介词后：about whether…
不定式 to do 前：whether to do
重点语法归纳
二、情态动词表推测（may/might/must/can’t）
3. 时态呼应
主句为一般现在时，从句时态根据实际；
主句为一般过去时，从句用相应过去时态。
