GRAMMAR 一問

i could fly in the sky-->啱
fly 係動詞
can係助动詞

過去式的被動句
e.g.She was killed yesterday.
was=過去
killED=被動

Um..."I could fly in the sky" is not bad, ut I don hear that a lot, cuz ppl may mix up with the polite form of "can".

I would say "I used to be able to fly." (I don think you need "in the sky." When you fly, of course you fly in the sky)

i could fly in the sky
fly 係動詞
過去式的被動句係甘樣
I had did.....by (n)

i can flew in the sky before

好d

i could fly in the sky 係岩,
你都可以講 I used to fly in the sky.
意思係一樣


I can flew in the sky係錯嫁
can 後面要 bare infinitive
所以唔可以用flew,要用fly



CAN 係 modal verb
fly 先自係verb


passive voice
係唔會用do did does
所以你錯咗喇
應該係
Subject + was /were + ppt(過去分詞)+ by + Object

eg. Sally ate the fish yesterday.←active voice
改為 The fish was eaten by Sally yesterday.←passive voice
