Unit 5 Fun Clubs重點(diǎn)語(yǔ)法歸納（記憶版）
情態(tài)動(dòng)詞can的用法
一、基本用法
can是情態(tài)動(dòng)詞，表示說(shuō)話人的主觀看法或語(yǔ)氣。它沒(méi)有人稱和數(shù)的變化，也不能單獨(dú)在句子中做謂語(yǔ)，但它可以與其后的不帶to的動(dòng)詞不定式一起構(gòu)成復(fù)合謂語(yǔ)。
1.can表示能力，常被譯成“能，會(huì)”。過(guò)去式could，否定形式 couldn't。
I can sing English songs.我會(huì)唱英語(yǔ)歌曲。
2.表示請(qǐng)求或許可，常被用來(lái)請(qǐng)求對(duì)方的許可，或表示說(shuō)話人自己的許可。
Can I help you？我能幫你忙嗎？
Can you go to the picnic with us tomorrow？明天你能和我們一起去野餐嗎？
3.can的否定式和縮略式。can的否定形式是can not或 cannot，其縮略形式是can't。
注意 can的陳述句變?yōu)橐蓡?wèn)句時(shí)，應(yīng)直接將can移到主語(yǔ)前面。肯定答語(yǔ)為“Yes，主語(yǔ)+can.”，否定答語(yǔ)為“No，主語(yǔ)+can't.”。
二、特殊用法
1.“can't+動(dòng)詞原形”，一定不可能，表示一種有把握的否定推測(cè)。
It's Sunday today. Mr.Li can't be in the office.今天是星期天。李老師不可能在辦公室。
2.can表示“請(qǐng)求，許可”時(shí)，相當(dāng)于may，但語(yǔ)氣沒(méi)有may嚴(yán)肅。Can I...？意思是“我可以/能……嗎？”。肯定回答：Yes, you can./Yes, please./Certainly./Of course./Sure.等。否定回答：No,you can't/mustn't./Sorry.../ I'm afraid not.等。
三、難點(diǎn)突破
can/could表示“請(qǐng)求”及“許可”含義時(shí)，could比can的語(yǔ)氣更加委婉、客氣，常用于“Could I/you...？”句式中，表示“我/你能……嗎？的意思。肯定回答用can/may，不用 could。
—Could I look at your pictures？我能看看你的照片嗎？
—Of course,you can.當(dāng)然了，你可以看。
