She is ill.What a pity! But next time when you are free, you must tell me.Ok, I will. But I have to wait until my mom gets better.(2) need的使用l 课文原句重现：That means you don't need to water the garden. l 结构：此句中的need为实义动词，其否定形式要借助助动词do来完成，即dont need tol 语法：need的用法1. need用作情态动词时，表示“需要”，后面直接跟动词原形，且无人称、数的变化，常用于疑问句和否定句中。e.g. Need I finish my homework now? 我需要现在完成作业吗？ 2. need作实义动词时，常用于以下几种情况： A) need sth.
