    1. "Is that doctor happy every day?"

    此為否定句。其肯定句為 "That doctor is happy every day."

    一般以 Do/Does 為開頭的疑問句的句型裡面,至少要有一個主要動詞,如:feel、think、start。

    如果我們將這句話的 be 動詞改為主要動詞,則可以用 Does 的形式來提問問題。

    例:Does that doctor feel happy every day? (主要動詞 = feel)

    例:Do you play piano every day? (主要動詞 = play)

    be 動詞 (am/is/are) 為聯繫動詞,並不是主要動詞。

    聯繫動詞主要是連接主詞與受詞之間的關係,在用法上通常是在主詞之後並接形容詞或是名詞。

    例:My friend is skinny. --> be 動詞 形容詞

    例:She is a teacher. --> be 動詞 a/the/an 名詞

    2. "Do his dog and cat drink milk?"

    dog 跟 cat 同樣都是第三人稱的單數,而連接這兩個主詞的 and 就如同中文的 "和" 的意思

    藉由 "and" 把 dog & cat 由單數的第三人稱主詞變為複數

    所以提問問題的時候必須要用 "do" 而不是 "does"

    例:Do Tom and his friend play basketball in the park every day?

    例:Do they ride bicycle to school every morning?

    如果主詞是單數形式,則要用 "does" 而不是 "do"

    例:Does his cat drink milk?

    例:Does his dog drink milk?

    例:Does Tom play basketball in the park every day?

    例:Does Tom's friend play basketball in the park every day?

    Is that doctor happy everyday?

    因happy是形容詞,不是動詞,故要以be動詞Is來造疑問句。例句:Is his girlfriend beautiful? (他女朋友漂亮嗎?)beautiful(漂亮的)是形容詞,故句中要有be動詞才完整。

    Do his dog and cat drink milk?

    主詞是his dog and cat,是複數第三人,drink是動詞,故要用助動詞Do來造疑問句。例句:Do your parents know the teacher?(你父母認識這位老師嗎?)parents(父母、雙親)是複數,know是動詞,故要以Do來造疑問句。

    這個句子把它改回成直述句,你就比較看的懂了

    That doctor is happy every day.

    S + be V + SC.

    happy是形容詞當主詞的補語

    形容詞前要用be 動詞連接

    所以只能用 is

    E.g. Jenny is beautiful.

    Is Jenny beautiful?

    第二句 Do his dog and cat drink milk?

    因為主詞是二隻動物,要看成複數,所以疑問句的助動詞要用do

    E.g. Do the girls go to the park on Sundays?

    1. 因為happy是形容詞, 要用動詞來修飾它

    2. 因為一個句子不能有2個動詞..........
