eng problem

動詞方面有兩種：連綴動詞及動作動詞。很明顯動作動詞就是表示主詞「在做甚麼」。如 hit (擊)，kiss (吻)。致於連綴動詞就是表示主詞「是甚麼」。be 就是最常用的連綴動詞，而 be 因為主詞的第幾身作出變化如 am，is，are：
I am a boy. / It is a dog. / They are students.
然後又因為時間性再變身如 was，were：
I was a baby. / We were babies.
還有 been 同 being (簡直十八變)

輔助動詞： (沒有字意)
do 可輔助主要動作動詞構成否定句或問句。
e.g. She dances. / She does not dance. / Does she dance?
be 在主要動詞前，而主要動詞加 -ing ，那就是作進行式。在講成進行式的問句時亦會將輔助動詞 (be) 放到句子頭。
e.g. You are reading a book. --> Are you reading a book?

Are < means 是否
Do 後面 + verb 動詞(for example: walk)

Are you a boy??<< 後面無verb 就用are
Do you (love) me? love 係動詞 所以用do
如果係過去式的話
i did my homework yesterday < 變返Questions
(Did)<<變過去式 you do(<<還原) your homework yesterday?

幾時用do?
1)They are do the homework.
2)l am doing my homework.

幾時用are去問人野?
1)What are you doing?
2)Are you want to watch TV?

Do (sbd) + VERB ~~~~

Are (sbd) + ADV ~~~~

do is followed by a verb but are is followed by an adjective
