3a
Fill in the blanks with the correct forms of
the verbs in brackets.
1. know; do 句意“我不知道明晚参加迈克的生日聚会的事怎么做？”
don't 后跟动词原形；what to+动词形式，复合不定式结构。
2. think 本句表达一客观事实，主语parents是复数形式，故用一般现在时
态。句意：我父母认为我应当为下周的英语考试而学习。
3. go; will be 本句是含 if 条件状语从句的主从复合句；应遵循主将从现原
则。句意：如果我去参加聚会，他们会很失望。
4. tells; have 本句为 but 连接的并列句，后半句为一般现在时，故前半句
也应是一般现在时，主语 Mike 是第三人称单数形式，故填 tells；
don't 后跟动词原形。

在英语里, 当句子的主句为将来时态时, 它所引导的时间状语从句和条件状语从句都使用一般现在时来表示将来时间, 这在英语里被称为“主将从现”。主句的将来时态并不仅限于我们这一课里所学习到的“will＋动词原形”构成的一般将来时, 还包括be going to＋动词原形、be doing所表示的一般将来时以及我们以后会学到的其他的将来时态。例如:
What is he going to do when he grows up
他长大了想干什么？
We are leaving for Amoy tomorrow if it doesn’t rain.
