CanIuseyourtelephone?我能用一下你的电话吗？CouldIuseyourtelephone?我能用一下您的电话吗？2.can和beabletocan和beableto都可以解释为“能够、可以”。可以表示“有能力来做某事、有时间来做某事，有办法来完成某事”等等。我们在区别他们时，需要注意的Grammara.在表示现在或过去的智力、体力、技能等方面的“能力”时,can、could常可与beableto互换。Icanswimnow.=Iamabletoswim.我会游泳。b.can表示“能够做某事”，不一定就真的做了。而beableto表示“有能力做某事”。说明是真的尝试过了，做过了这件事情。所以赶拍胸脯说自己有这个能力。比如：

Icanswim300metersnowandlastyearIwasabletoswim100meters.我现在能够游300米，去年我可以游100米的。这句话中，第一部分“Icanswim300metersnow”，表示“我现在能够游300米”只是说说而已，并不说明已经游过了。而后面部分“lastyearIwasabletoswim100meters”，表示我去年的确是游过了，可以游100米的。

Grammarc.beableto有比can更多的形式。从时态上来说：can做为情态动词，只有现在时和过去时。而beableto则有比can更多的形式，除了现在时和过去时，还有将来时和完成时。

Hewillcomeifhecan.=Hewillcomeifheisableto.Icanseeyoutomorrow.＝I’llbeabletoseeyoutomorrow.（将来时使用willbeableto结构）

Icouldn’tunderstandhim.=Iwasn’tabletounderstandhim.（过去时使用was/wereableto结构）Hesaidhecouldseemenextweek.=Hesaidhewouldbeabletoseemenextweek.(过去将来时使用wouldbeableto结构)

请大家注意，如果要体现将来时和完成时，那只能用beableto。因为can作为情态动词只有现在时和过去时。Grammar综合上面的几点，我们简单总结一下：can和beableto在表示个人能力时，一般可以进行互换。Can表示“能够做某事”，是未经尝试过的能力；而beableto则多表示“有能力做某事”多为已经过事实验证的。Can用于现在时和过去时；而beableto由于有个be动
