特殊疑問句是就句中的某一部分提問的疑問句.它的句首用疑問詞,句尾的聲調(diào)下降.它與一般疑問句的區(qū)別在于：它不能用yes 或no來回答.常用的疑問代詞有what,which,who,whom,whose,疑問副詞有when,where,why和how等.例如：

　　What's this in English?

　　What color is it?

　　How much are these pants?

　　When is your birthday?

　　特殊疑問句的構(gòu)成可分兩類：

　　1. 當(dāng)疑問代詞做主語或修飾主語時(shí),它的語序和陳述句相同.例如：

　　Who are in the classroom?

　　Who is your English teacher?

　　What's your favorite color?

　　2. 當(dāng)疑問代詞作表語、賓語或修飾表語和賓語,或疑問副詞作狀語或修飾狀語時(shí),它要用倒裝詞序.有一點(diǎn)需要說明的是：當(dāng)疑問代詞或疑問副詞修飾的名詞是介詞的賓語時(shí),除正式語體外通常要把介詞放在句尾.例如：

　　What do you do?

　　Why do you like koalas?

　　What's she doing?

　　Who are you looking at?
