（2）疑問句（Interrogatives）

陳述句	疑問句
（1）I am a boy.	Am I a boy？
（2）Mary has a bicycle.	Has Mary a bicycle？ Does Mary have a bicycle？（美）
（3）He went to Boston yesterday.	Did he go to Boston yesterday？
（4）John can speak English.	Can John speak English？
（5）There are two girls in the room.	Are there two girls in the room？
（6）Here is a house.	Is here a house？

由上諸例可知，疑問句是將主語和動詞的位置顛倒而構成的。

例（1）（2）僅限于 be 和 have 兩動詞，即它們不需助動詞，但在 have 的場合，美國人常用助動詞 do 來構成疑問句，又 dare、need、used 等亦不需用 do。

例（3）表示凡無助動詞的句子變為疑問句時，必須用助動詞 do。

例（4）表示凡有助動詞的句子變為疑問句時，則將（第一個）助動詞放在主語之前即可。

例（5）和（6）表示 there 和 here 雖非主語，但在疑問句時，仍將動詞放在它們之前。

有疑問詞的疑問句

1. 主語為疑問代詞，或為疑問形容詞所修飾時，則句法與陳述句者同，只加一問號（？）于句尾即可。

例：Who made that voice？

How many pieces are left？

2. 但在疑問副詞（why、when、what time，etc）的場合，則主語和動詞的位置仍須顛倒，而將疑問副詞放在句首。

例：Why（when、what time，etc）did John go to school？

注意：1. 否定陳述句改為問句時，通例將動詞放在主語前即可，但也有將 not 隨動詞置于主語之前者，在此等場合，最好用縮短形，如 Didn’t、Haven’t、Aren’t 等。

I did not read much. →Didn’t I read much？Did I not read much？

Jack is not ill. →Is not（Isn’t）Jack ill？Is Jack not ill？

2. have 用為“吃、學習”等意時，則概用 do 來作成疑問句。

例：Do you have dinner at seven？Does Bessie have any lessons in the afternoon？
