2)第三人称单数作主语时,用_____构成一般疑问句,回答用_______________.
do
do或don’t

have意为“有”,表示某人拥有某物。have在句子中有两种形式,即have和has。have用于第一人称(I, we)、第二人称(you)以及第三人称复数(they)和其他复数名词;而has则用于第三人称单数(he, she, it)和单数名词。
如:
I have an apple. 我有一个苹果。
Mary has an orange. 玛丽有一个桔子。
2) have/has句子的一般疑问句是在句首加助动词do或does,句尾用问号构成。除第三人称单数前用does外,其他都用do。第三人称单数前加does后,句中的谓语动词has应改为have。作简略回答时,肯定回答为:“Yes, 主语 + do/does.” ,否定回答为:“No, 主语 + don’t/doesn’t. ” 。
