5、（注意在回答中不可用could）。例如： Could I have the television on? 我能看電視嗎？ Yes, you can. / No, you can't. 可以/不可以。 在否定句、疑問句中表示推測(cè)或懷疑。例如：He couldn't be a bad man. 他不大可能是壞人(2) may/might 表示允許或請(qǐng)求；表示沒有把握的推測(cè)；may 放在句首，表示祝愿。might 表示推測(cè)時(shí)，不表示時(shí)態(tài)，只是可能性比may 小。(3) will/would 克表示請(qǐng)求、許諾、同意、過去的習(xí)慣等。但需要注意： would like；would like
