can/could用法考点
1.1.表示能力，意为“能，会”。could是can的过去式，表示过去的能力。
辨析：can和be able to的区别
情态动 用法
词
can 只能用于一般现在时和一般过去时。
be able to 可用于各种时态。表示经过努力做成某事只能用 be able to.
Will you be able to camera the lecture tomorrow?明天你能把讲座录下来吗？
1.2.表示推测，意为“可能”，常用于否定句和疑问句中。could既可以表示过
去的可能性，又可以表示现在的可能性，其语气更弱一些。
例句This can't be the right road.不可能是这条路。
1.3.表示请求或允许，常用于“Can/Could l/you...?”句型中。could不表示过去，
而是表示委婉的请求，但答语只能用can.例－Could you help me work out the problem?你能帮我做出这道题吗？
－Yes,I can.是的，可以。
