第三单元的语法知识:

情态动词could构成问句常用于委婉地提出请求或寻求许可,意为“可以,能”;语气比can更委婉、客气;但并不表示过去,其答语没有固定格式,符合语境即可;

提出请求:

Could you please take out the rubbish?

你可以把垃圾倒了吗?

Could you please pass me the salt?

你能把盐递给我吗?

Could you please lend me some money?

你能借我点钱吗?

寻求许可:

Could I go out for dinner with my friends?

我可以和朋友出去吃饭吗?

(考点)以must开头的一般疑问句,其否定回答使用needn’t或don’t have to;

The minute 与 as soon as 均可引导时间状语从句,表“一...就...”;强调主句与从句的动作几乎同时发生;

当主句为一般将来时,从句使用一般现在时,即“主将从现”;
