3. if表示“如果”和“是否”的用法。
（1）在if引导的条件状语从句中，当主句是一般将来时，从句应用一般现在时表示 一般将来时。
如：如果明天不下雨，我们就去动物园。 If it doesn’t rain tomorrow, we will go to the zoo.
（2）if表示“是否”时，if或whether引导的是宾语从句（当从句中含有or not时， 常用whether)，宾语从句的时态由句意决定。
today.
易错点突破
2. 使用and和or时要注意以下几点。
（1）一般情况下，否定句中的and要变为or. 如：那个女孩既不会唱歌也不会跳舞。 The girl can't sing or dance.
（2）连接的两个部分都有否定词，应使用and连接。 如：大部分人认为月球上没有水和空气。 Most people think there is no water or no air on the moon.
