CanIuseyourtelephone?我能用一下你的電話嗎？CouldIuseyourtelephone?我能用一下您的電話嗎？2.can和beabletocan和beableto都可以解釋為“能夠、可以”。可以表示“有能力來做某事、有時間來做某事，有辦法來完成某事”等等。我們在區(qū)別他們時，需要注意的Grammara.在表示現(xiàn)在或過去的智力、體力、技能等方面的“能力”時,can、could?？膳cbeableto互換。Icanswimnow.=Iamabletoswim.我會游泳。b.can表示“能夠做某事”，不一定就真的做了。而beableto表示“有能力做某事”。說明是真的嘗試過了，做過了這件事情。所以趕拍胸脯說自己有這個能力。比如：

Icanswim300metersnowandlastyearIwasabletoswim100meters.我現(xiàn)在能夠游300米，去年我可以游100米的。這句話中，第一部分“Icanswim300metersnow”，表示“我現(xiàn)在能夠游300米”只是說說而已，并不說明已經(jīng)游過了。而后面部分“l(fā)astyearIwasabletoswim100meters”，表示我去年的確是游過了，可以游100米的。

Grammarc.beableto有比can更多的形式。從時態(tài)上來說：can做為情態(tài)動詞，只有現(xiàn)在時和過去時。而beableto則有比can更多的形式，除了現(xiàn)在時和過去時，還有將來時和完成時。

Hewillcomeifhecan.=Hewillcomeifheisableto.Icanseeyoutomorrow.＝I’llbeabletoseeyoutomorrow.（將來時使用willbeableto結(jié)構(gòu)）

Icouldn’tunderstandhim.=Iwasn’tabletounderstandhim.（過去時使用was/wereableto結(jié)構(gòu)）Hesaidhecouldseemenextweek.=Hesaidhewouldbeabletoseemenextweek.(過去將來時使用wouldbeableto結(jié)構(gòu))

請大家注意，如果要體現(xiàn)將來時和完成時，那只能用beableto。因為can作為情態(tài)動詞只有現(xiàn)在時和過去時。Grammar綜合上面的幾點，我們簡單總結(jié)一下：can和beableto在表示個人能力時，一般可以進行互換。Can表示“能夠做某事”，是未經(jīng)嘗試過的能力；而beableto則多表示“有能力做某事”多為已經(jīng)過事實驗證的。Can用于現(xiàn)在時和過去時；而beableto由于有個be動
