Does he have relatives here?是正確的
一般陳述句是 He has relatives here.這里的動詞根據(jù)主語變成第三人稱單數(shù)的has 如果是疑問句當然也要用助動詞do的三單形式does來提問 但是此時動詞就是不必再變了 也就是只需要變一個
has 三單一（第三人稱單數(shù)）
have 原型咯
had 是過去時態(tài)的
He had a nice weekend.他周末度的很愉快(那么現(xiàn)在已經(jīng)是新的一周了)
_______(am,is,are,do,does) you friends?
這個句子很搞笑 確是如一樓所言 看不懂
但是莎士比亞有句話 Friend or foe?(是朋友還是敵人)
省略了 Is he a friend or foe?或者 Are you a friend (of mine) or foe(against me)?
所以 Are you friends?(試探性詢問)對方是不是朋友.這個實在很弱智的題目（我的意思是這個出題者很NC）
因為 沒有人會這么問呀.
當然也不排除一樓的 Are they your friends?
課本也可能出錯喲
如果是Are you friends?= Are you (my) friends?
Yes,we are.(雙方要握手了)
No,we aren't.(要開打了)
如果是Are they your friends?（他們是你朋友嗎?）
Yes,they are.
No,they aren't.
趨勢一：他們不是 我們要和他們開打了（怎么覺得我最近挺暴力的）
趨勢二：他們 我不認識呀（路過 沒事 沒事）
最后那個.
Does he have a roommate?是正確的
看第一問題的解釋吧
He has a roommate.
Has he a roommate?
Does he have a roommate.都是正確的
再比如 He sees the film with me.
Does he see the film with you?
