小學(xué)四年級英語考點(diǎn)之一般疑問句及特殊疑問句

字號:

句子基本是:簡單陳述句,由簡單陳述句轉(zhuǎn)變成肯定句,否定句,疑問句。疑問句是用來提出問題。英語中有四種疑問句: 一般疑問句、特殊疑問句、選擇疑問句和反意疑問句。我們現(xiàn)在已經(jīng)接觸到了前兩種疑問句。后兩種疑問句以后我們還會學(xué)到.
     一般疑問句:
    英語中要用 yes和no 來回答的疑問句叫一般疑問句。如:
    1)Is it hot ?Yes, it is .\No, it isn’t.—— be動詞引導(dǎo)
    2)Is it a car ?Yes, it is .\No, it isn’t .—— be動詞引導(dǎo)
    3)Is this your ruler ?Yes, it is .\No, it isn’t .—— be動詞引導(dǎo)
    4)Do you like bananas ?——含實義動詞
      Yes, I like bananas. \ No, I don’t like bananas.
    5)Can Ming hear a drill ?——含情態(tài)動詞
