語(yǔ)法拓展
特殊疑問(wèn)句
特殊疑問(wèn)句是對(duì)句中某一部分內(nèi)容提出疑問(wèn)的問(wèn)句，是指以“what, who,when,where,why,how等”開頭的疑問(wèn)句，也稱wh-疑問(wèn)句。特殊疑問(wèn)句與一般疑問(wèn)句不一樣，它不能用yes或no回答。
1.構(gòu)成：疑問(wèn)詞+其他句子成分？其中，疑問(wèn)詞包括疑問(wèn)代詞和疑問(wèn)副詞兩種。
疑問(wèn)代詞有：what,who,which,whose,whom
疑問(wèn)副詞有：how,why,when,where
（1）倒裝句結(jié)構(gòu)：疑問(wèn)詞+一般疑問(wèn)句？此時(shí)，疑問(wèn)詞及其所修飾的部分不作主語(yǔ)，即作賓語(yǔ)、定語(yǔ)、表語(yǔ)、狀語(yǔ)等。
What do you like for lunch?（作賓語(yǔ)）
（2）陳述句結(jié)構(gòu)：疑問(wèn)句+謂語(yǔ)動(dòng)詞+賓語(yǔ)/表語(yǔ)/狀語(yǔ)？此時(shí)，疑問(wèn)詞及其所修飾的部分作主語(yǔ)。
Who teaches you math?（作主語(yǔ)）
Whose shoes are on the chair?（與名詞一起作主語(yǔ)）
2.疑問(wèn)詞小結(jié)：
（1）針對(duì)事物的名詞提出疑問(wèn)，疑問(wèn)詞用what。
What's your favorite subject?
（2）對(duì)指人的名詞或代詞提問(wèn)用who。 Who's he?
（3）對(duì)具體時(shí)間提出疑問(wèn)，用when。
When do you play basketball?
（4）對(duì)地點(diǎn)提出疑問(wèn)，用where。 Where's my pen?
（5）對(duì)原因提出疑問(wèn)，用why。 Why do you like art?
（6）對(duì)方式、程度、價(jià)格等提出疑問(wèn)用how。
