    can 和 be able to 的差別

    can 是助動詞

    be able to / 的 able 是形容詞,所以必需和be動詞在一起。

    be able be 可以和所有助動詞一起用,不定是 will

    因助動詞,和助動詞不可一起用,所以助動詞後面的 "可以" 一定要用 be able to

    例如 :

    I will can skate in a month. X

    I will be able to skate in a month. O

    I should can swim for one hour. X

    I should be able to swim for one hour. O

    I might be able to go home at 6 : 00. X

    I must be able to pass the test. O

    You had better be able to do this.

    希望對你有幫助。

    一個完整的句子只能有一個助動詞喔

    順帶一提

    像can 跟 be able to一樣可以互換的助動詞有:

    should= ought to +R.V

    例:Students should study hard. = Students ought to study hard.

    must = have to+R.V

    例:We must be a helpful person.(語氣較強烈)= We have to be a

    helpful person(語氣較婉轉)

    will 則可以替換成be going to 或是shall

    shall多用在第1人稱,未來簡單式

    例: I shall die no matter what things happen to me.

    對阿

    因為will是助動詞,can也是助動詞

    兩個助動詞並不能放在一起喔

    不過can和be able to都是一樣的意思→能

    他們兩個之間的差別是can是助動詞,而be able to不是
