【導(dǎo)讀】can表示現(xiàn)在的能力，could表示過(guò)去具有某種能力。力、克服困難做成某事，相當(dāng)于managed。此時(shí)could不是can的過(guò)去式，它表示推測(cè)的可能性比can小。will與would均可用于主語(yǔ)是第二人稱的疑問(wèn)句中，表示征求。意見(jiàn)或提出請(qǐng)求，此時(shí)would并不表示過(guò)去，而表示委婉語(yǔ)氣。★表示習(xí)慣和傾向性?！飐hould表示義務(wù)或責(zé)任、建議或勸告、推斷等。should還可以表示驚訝、失望、遺憾等情感，此時(shí)意為“竟會(huì)”?！颿an’t可表否定的推測(cè)和判斷，意為“不可能”。II.從括號(hào)內(nèi)選擇合適的內(nèi)容完成下面對(duì)話。
