情态动词must, can, could表示推测
我们学习过情态动词can和could表示“能够”，表示对现在或将来的推测，意为“会，可能”，往往用于否定句和疑问句。用于疑问句时，can比could表示的“可能性”要大；用于否定句时，cannot (can’t) 表示“不可能”。如：
You can’t be serious!
你不是认真的吧！
could则可用于肯定句、否定句和疑问句。在以下例句中，can和could均表示可能：
He could be in pain.他可能很疼。
That could be harmful!那可能有害！
Can/Could this be true?这有可能是真的吗？
