his favorite subject is English.（对划线部分提问）答案是（what）（is）his favorite subject,可以
说what does吗?如果不可以,是不是可以说what does he favorite subject呢?
答
what does不可以。
what does he favorite subject也不可以。what does he favorite subject？这个问句就是不符合语法的，首先favorite subject（最喜欢的学科）是名词，所以用he就不行，要用物主代词his；而does是助动词do的第三人称，是可以用在有动词的问题中的，比如what does he like best?like是动词。这里应该用系动词is。
答
His favorite subject is English.
Is his favorite subject English?
What is his favorite subjiect?
为了避免错误,把句子先变为一般疑问句,再变为特殊疑问句,这样就不会错了.
