语法
一般将来时
概念：一般将来时表示将来某个时间要发生的动作或存在的状态，也表示将来经常或反复发生的动作。
构成：
(1) will + 动词原形
例句：I will play football tomorrow.
讲解：will 是一般将来时的助动词，没有人称和数的变化，不管主语是 I、you、he、she、it 还是 they，后面都直接跟动词原形。
练习：请用 will + 动词原形翻译下列句子。她下周将去看望她的祖父母。我们明天将打扫教室。
(2) be going to + 动词原形
例句：He is going to visit his uncle this weekend.
讲解：be 动词要根据主语的人称和数进行变化。begoingto结构强调事先经过考虑的打算、计划，也可表示有迹象表明即将发生某事。
练习：用 be going to + 动词原形改写下列句子：They will have a party tonight. I will buy a new book tomorrow.
