　�、� should可表示“勸告”、“建議”、“驚奇”等意思。We should speak to old people politely.(我們應(yīng)該禮貌地對(duì)老人講話)

　�、醱ould表示過(guò)去的“意愿”、“決心”等。He would sit near the fire every time he returned home.(每次他回到家中總要坐在火爐邊)

　　would也可以表示現(xiàn)在的情況,表達(dá)說(shuō)話人向?qū)Ψ教岢龅囊��?語(yǔ)氣比“will”婉轉(zhuǎn)、客氣。在日常會(huì)話中,“我想要…”通常用“I would like to”或“I should(I’d) like to”來(lái)表示。如：Would you like to have a rest at the moment?(你現(xiàn)在想要休息一下嗎？)
