Grammarfocus

情態(tài)動(dòng)詞can表示邀請(qǐng)。

句型結(jié)構(gòu)：Can+主語(yǔ)(you)+動(dòng)詞原形+其它?例如：Canyouetomyparty?Canyougoshoppingwithme?Howtomakeaninvitation?

Summary

有時(shí)can也可以換成could,用could更禮貌。can是一個(gè)常見(jiàn)的情態(tài)動(dòng)詞，表示說(shuō)話人的語(yǔ)氣或情態(tài)，基本意思是“能；會(huì)”。它沒(méi)有人稱(chēng)和數(shù)的變化，在句子中不能單獨(dú)作謂語(yǔ)，其后必須跟實(shí)義動(dòng)詞原形。

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

Summary情態(tài)動(dòng)詞有：may/might,can/could,must,haveto,shall/should,will/would,need等。不能獨(dú)立作謂語(yǔ)，只能和動(dòng)詞原形一起構(gòu)成謂語(yǔ)沒(méi)有人稱(chēng)和數(shù)的變化。(haveto除外)否定形式：在其之后加not(haveto除外)。疑問(wèn)形式：情態(tài)動(dòng)詞提到主語(yǔ)之前(haveto除外)。

may/might情態(tài)動(dòng)詞含義及用法例句may/might可能可以

MightIaskyouaquestion?

Thereportsaysthatitmightrain．

Hesaidhemightetomorrow.表示請(qǐng)求，許可，意為“可以”，語(yǔ)氣比may更委婉。表示推測(cè)，意為“可能”，語(yǔ)氣較委婉，可能性低于may。may的過(guò)去式,意為“可能”haveto的意思是“必須、不得不”強(qiáng)調(diào)由于客觀原因而必須做某事。性質(zhì)如下：

havetohaveto后接動(dòng)詞原形；haveto有人稱(chēng)、數(shù)和時(shí)態(tài)的變化；第三人稱(chēng)單數(shù)形式為hasto,過(guò)去式是hadto；

疑問(wèn)形式和否定形式要借助于助動(dòng)詞do,does或did1.Tomhastogohomeonfoot.否定句______________________________疑問(wèn)句______________________________肯/否定回答__________________________Tomdoesn’thavetogohomeonfoot.DoesTomhavetogohomeonfoot?Yes,hedoes./No,hedoesn’t.PracticePractice2.Lilyhadtogohomeonfootlastnight.否定句______________________________疑問(wèn)句______________________________肯/否定回答__________________________Lilydidn’thavetogohomeonfootlastnight.DidLilyhavetogohomeonfootlastnight?Yes,shedid./No,shedidn’t.must“必須”沒(méi)有人稱(chēng)和數(shù)的變化。
