Grammar Focus (P35)
表示推测的情态动词。
在英语中，表示对某件事物的确定程度，即表示推测的时候，我们通常会用到以下情态动词，must, might, could, may, can’t, couldn’t.
一. can和could的区别和用法
1. can表示体力和脑力方面的能力, 或根据客观条件能做某种动作的“能力”。 例如：
Can you speak English？
Can you make a cake？
can用在否定句和疑问句中时有时表示说话人的 “猜测”或 “不肯定”。
例如：
Can the news be true？
(在日常会话中, can可代替may表示“允许”, may比较正式)
2. could 是 can的过去式, 表示过去有过的能力和可能性, 还有怀疑和不肯定的意思(在否定和疑问句中)。
e. g.
She couldn’t skate when she was five years old. （能力）
At that time we thought the story could be true． （可能性）
could用来提问, 是有礼貌的请求 Could.... Please 语气较为婉转。
2. might的用法:
a. might可以代替may, 表示现在时间的动作，但语气较为婉转客气或更加不肯定。
e. g.
Might I take a suggestion？
b. might用来表示现在时间时, 还可表示”规劝”。
