1、2022春七年級(jí)英語下冊(cè) Unit 7 Abilities語法專練課時(shí)作業(yè) （新版）牛津版
這三個(gè)詞都是情態(tài)動(dòng)詞。情態(tài)動(dòng)詞本身有一定的意義,但沒有人稱和數(shù)的變化,需要和實(shí)義動(dòng)詞一起構(gòu)成句子的謂語部分,表示說話者的情感、態(tài)度和語氣。
1.can和could表示能力。
(1)can意為“能,會(huì)”,用來表示某人現(xiàn)在的能力;could是can的過去式,用來表示某人過去的能力。例如:
I couldn’t understand his words last year,but now I can.去年我還不能理解他的話,但現(xiàn)在我能理解了。
(2)can表示能力時(shí),與be able to同義,二者
2、一般可互換,但can只有一般現(xiàn)在時(shí)和一般過去時(shí)兩種時(shí)態(tài),而be able to中的be動(dòng)詞的形式根據(jù)句子所用時(shí)態(tài)變化。例如:
You will be able to pass the exam tomorrow.明天你能通過考試。
2.can,could和may表示許可。
情態(tài)動(dòng)詞can,could和may可以用來表示請(qǐng)求或許可。情態(tài)動(dòng)詞could表示一種委婉的語氣,比can表達(dá)更有禮貌,常用于問句中。may較正式。
注意:對(duì)情態(tài)動(dòng)詞could的回答不能用could,只能用can。例如:
—Could I borrow your ruler?我可以借你的尺子嗎?
—Yes,you
3、can./Sorry,you can’t.是的,你可以。/對(duì)不起,你不可以。
