如果你仲對小學英文堂有d記憶,可能會記得一個名詞,叫做第三身單數(third person singular)。
第一身係我(I),第二身係你(you),第三身係他/她/它/牠(he/she/it)。
當動詞接住第三身名詞時,呢個名詞又係單數(即係得一個他/她/它/牠),動詞就加 s,叫做 third person singular -s。所以:
Don't put the dictionary away, i needs it 錯,因為係第一身。
Don't put the dictionary away, we needs it 都錯,因為唔係單數。
咁明唔明?
The sentence on your exercise is wrong.
You are correct that I/you/we - do not need to put "s".
So the correct sentence should be :
Don't put the dictionary away, I need it.
