情態助動詞真的有點小難,因為同一個字可以用在不同地方,所以容易混淆。不過多練習一定有幫助。首先要知道他們用在什麼地方,再來注意日常生活聽到的是不是跟學到的依樣,有機會的時候把他們用出來,這樣就會記住了。
最近很懶散的潔西要好好振作一下了,有關文法的問題的話,歡迎提問,會盡力回答。 看影片或許會比較清楚,有不清楚的地方。
情態助動詞用來表示說話者的態度,比方說某些事是可能發生的,必須的,適合的,要求許可的等等。很多時候情態助動詞有不同的用法。
情態助動詞:can, could, may, might, must, ought to, should, will, would, shall, had better
情態助動詞片語:be able to, be going to, be supposed to, have to, have got to
A Ability 表能力:can, could, be able to
a can 用來表示體能,常與感官動詞連用,表示已經學會的技能,表可能性,非正式時表允許。否定
是 cannot 或 can’t。
I can do 50 push-ups. sit-ups
She can see the tower from here.
They can speak French.
You can easily find a good restaurant in Taipei.
You can give me a call before 9 p.m.
He can’t play basketball.
What’s in the soup? I can taste something funny.
b could 表示過去的能力,否定是 could not 或 couldn’t
I couldn’t speak English when I was little.
She could ride a bike when she was 7.
c be able to 可以用再現在,過去,未來。現在式多用 can ,而不用 be able to 。表達過去 could 跟 was/were able to 都可以,未來跟不定詞後面用 be able to 。
He’s able to swim.
He can swim.
My parents weren’t able to use the computer a year ago.
My parents couldn’t use the computer a year ago.
I will be able to finish it on time.
He wants to be able to ski.
練習一:填入 can, could, be able to,儘可能用 can 跟 could 。有些句子是否定的。Longman P118
