用can提出直接建議（常用于口語，語氣較隨意）Wecaneatinarestaurantthisevening.今晚我們可以在餐館吃飯。

could表示有禮貌的請求，語氣委婉，常用于非熟人之間或晚輩對長輩、下級對上級的場合?！狢ouldyoutellusifitsnowsinwinterinAustralia?—Sure.—請告訴我們，澳大利亞冬天下雪嗎？—當(dāng)然可以。用could提出委婉建議（語氣更禮貌、含蓄，適合正式或陌生場景）MaybeIcouldgiveyoualift/ridetothesupermarket.

也許我可以讓你搭我的車去超市。Youcouldtryreadingtheinstructionsbeforeusing.

你可以試著在用前先讀一下說明書。could的其他用法如下：(1)could為can的過去式，表示能力。Hecouldrideabikeattheageoffive.他五歲時就會騎自行車了。拓展(2)表示可能性，指對過去、現(xiàn)在或?qū)淼哪撤N可能的推測。ThebookcouldbeLily’sbecauseshelikesreadingbooks.

那本書可能是莉莉的，因為她喜歡看書。(3)表示建議。Youcouldgotherebybus.你可以乘公共汽車去那兒。4.
