If 條件句基本概念
If 子句表示 條件成立時,主要子句的事情會發生。
基本句型:

If 條件句的重要規則
1️⃣ If 子句不用未來式

正確:If it rains, I won’t go.
因為 If 子句要用現在式表示未來。
2️⃣ If 子句可放句首或句尾
If Joe studies hard, he will get good grades.
= Joe will get good grades if Joe studies hard.
3️⃣ 主句也可以是祈使句或情態動詞

If it stops snowing, we can go out.如果雪停了,我們可以出去。
二、Although / Though 讓步子句

Although he is young, he is very brave.雖然他年紀小,但他很勇敢。
重要文法提醒
1️⃣ Although / Though 不可和 but 同時使用
錯誤:
Although he was tired, but he kept working.
正確:
Although he was tired, he kept working.
2️⃣ 可以放句首或句中

= We played outside although it rained.

If | 如果(條件) | If it rains, I won’t go out. |
Although / Though | 雖然(讓步) | Although it rains, I will go out. |
簡單理解:
If → 條件成立才發生
