2、般疑問(wèn)句的特點(diǎn),1）由be動(dòng)詞(is,am, are)來(lái)開(kāi)頭 eg: Is she your teacher? 2）由情態(tài)動(dòng)詞( 如：can will ）來(lái)開(kāi)頭 eg: Can you give me a hand? 3）由助動(dòng)詞（如：do， does ）來(lái)開(kāi)頭 eg: Does he play sports every day,一般疑問(wèn)句的回答,一般疑問(wèn)句常用Yes或No回答. 肯定回答： Yes,主語(yǔ)be (情態(tài)動(dòng)詞、助動(dòng)詞) 否定回答： No,主語(yǔ)be (情態(tài)動(dòng)詞、助動(dòng)詞) not,如何將一個(gè)肯定的陳述句改為一般疑問(wèn)句,秘訣一：找be動(dòng)詞或情態(tài)動(dòng)詞,看句中有無(wú)be動(dòng)詞或情態(tài)動(dòng)詞，如有，把

(你在哪個(gè)班？) Im in Class Four, Grade Five. (我在五年級(jí)四班。,特殊疑問(wèn)句其實(shí)就是用疑問(wèn)詞引導(dǎo)的疑問(wèn)句它的結(jié)構(gòu)就是,特殊疑問(wèn)句 = 特殊疑問(wèn)詞+ 一般疑問(wèn)句,常用的特殊疑問(wèn)詞,What-問(wèn)“什么” When-問(wèn)“什么時(shí)候” Where- 問(wèn)地點(diǎn)“哪里” Which-問(wèn)“哪一個(gè) Why
