情態動詞can表示邀請。

句型結構：Can+主語(you)+動詞原形+其它?例如：Canyouetomyparty?Canyougoshoppingwithme?Howtomakeaninvitation?

Summary

有時can也可以換成could,用could更禮貌。can是一個常見的情態動詞，表示說話人的語氣或情態，基本意思是“能；會”。它沒有人稱和數的變化，在句子中不能單獨作謂語，其后必須跟實義動詞原形。

Summarycan可以表示邀請。表示邀請時，could比can更禮貌、更委婉。同時，can還有其他用法。1.MybrothercanswimbutIcan’t.表能力，“能夠；會”2.CanIreadyournewbook?表許可，“可以；能夠”3.Thebookcan’tbeJack’sbecausehisisblue.表推測，常用于否定“不可能”或者疑問句“可能”

Summary情態動詞有：may/might,can/could,must,haveto,shall/should,will/would,need等。不能獨立作謂語，只能和動詞原形一起構成謂語沒有人稱和數的變化。(haveto除外)否定形式：在其之后加not(haveto除外)。疑問形式：情態動詞提到主語之前(haveto除外)。

may/might情態動詞含義及用法例句may/might可能可以

MightIaskyouaquestion?

Thereportsaysthatitmightrain．
