【語法透視】：一般疑問句的用法解析
一般疑問句
一般疑問句也可稱為 "yes / no questions"，因這種問句通常用yes / no來回答，相當於漢語中的"……嗎?"其語序是：系動詞be / 助動詞/ 情態動詞＋主語＋其他成分? 如：
Are you from Japan?
Yes I am. / No I'm not.
Is her sister doing her homework now?
Yes she is. / No she isn't.
Does he work in a bank?
Yes he does. / No he doesn't.
Do you live near your school?
Yes I do. / No I don't.
Can you speak French?
Yes I can. / No I can't.
May I go home now?
Yes you may. / No you mustn't.
注意：
1.將陳述句變為一般疑問句時，如句中有be 動詞（am/ is /are）時，可直接將它們提至主語前。如主語為第一人稱，應將其改為第二人稱。如：
I'm in Class 2, Grade 1. →Are you in Class 2, Grade 1?
We're watching TV. →Are you watching TV?
2.陳述句中有情態動詞（can, may, must …）時，可直接將它們提至主語前，即可成為一般疑問句。如：
He can swim now. →Can he swim now?
The children may come with us. → May the children come with us?
3.陳述句中只有一個實義動詞作謂語且其時態為一般現在時，變為一般疑問句時要在句首加do或does 主語後的實義動詞用原形。如：
I like these animals. →Do you like these animals?
She wants to go to the movies. → Does she want to go to the movies?
4.一般疑問句一般讀升調。
5.一般疑問句有時不用yes或 no 回答。如：
—Are they in town now?
—I think so.
—May I sit here?
—Certainly.
—Does he like soccer?
—Sorry I don't know.
