3,一般疑問句:是指詢問事實(shí)的句子,此類句子必須用"yes",或"no"來回答.

　　如:Are you a student ？Yes, I am No, I'm not.

　　Is she a doctor？ Yes, she is. No, she isn't.

　　Does he work in a hospital ？Yes, he does. / No, he doesn't.

　　Did you watch TV yesterday evening? Yes, I did. / No, I didn't.

　　注意:

　　一般疑問句是在肯定句的基礎(chǔ)上,

　　①把動(dòng)詞be調(diào)到首位,其他照寫,末尾標(biāo)點(diǎn)符號(hào)變成問號(hào)即可.

　　②沒有動(dòng)詞be的句子則要在句首加上一個(gè)助動(dòng)詞(do,does,did)再把緊跟在后面的動(dòng)詞變回原形,末尾標(biāo)點(diǎn)符號(hào)變成問號(hào)即可.

　　這三個(gè)助動(dòng)詞也要根據(jù)人稱和時(shí)態(tài)來選擇,其中"does"只用于一般現(xiàn)在時(shí)主語是第三人稱單數(shù)的情況,而"did"只用于一般過去時(shí),不論主語是什么人稱和數(shù),都用"did" .一般疑問句有個(gè)重要的原則就是問和答要一致,即問句里的第一個(gè)單詞(助動(dòng)詞)和簡(jiǎn)略答句里的這個(gè)詞是一致的.

　　4,特殊疑問句:以特殊疑問詞(what , where , who , which , when , whose , why , how等)開頭引導(dǎo)的句子.此類句子應(yīng)該問什么就答什么,不能用"yes ,no"來回答.如:

　　What is this？

　　Where are you going？

　　Who played football with you yesterday afternoon？

　　When do you usually get up？

　　Why do you like spring best ？

　　How are you？

　　注意:

　　其中how又可以和其他一些形容詞連用組成特殊疑問詞組用來提問,如: how many(多少(數(shù)量)), how much(多少(錢)), how tall(多高), how long(多長(zhǎng)), how big(多大), how heavy(多重)

　　例句:How many pencils do you have ？

　　How many girls can you see ？

　　how many 用來提問可數(shù)名詞的數(shù)量,主要有以上三種搭配,

　　How many + 名詞復(fù)數(shù) + do you have 你有多少……

　　How many + 名詞復(fù)數(shù) + can you see 你能看見多少……

　　How many + 名詞復(fù)數(shù) + are there… 有多少……

　　七 完全縮略形式

　　1、簡(jiǎn)縮形式的變法：把倒數(shù)第二個(gè)字母，通常是元音字母變成' 但are除外，are要把a(bǔ)打成' 。Eg:he is=he's they are=they're

　　2、簡(jiǎn)縮形式和完全形式的漢語意思相同。

　　3、把完全形式變成簡(jiǎn)縮形式時(shí)，一定要注意第一個(gè)字母的大小變化。Eg:What is =What's

　　4、記住一個(gè)特殊變化;let's =let us 讓我們(不要把' 變成i) 5、記住：thisis 沒有簡(jiǎn)縮形式this's(錯(cuò)誤)

　　5.常見的縮略形式：

　　I'm=I am he's=he is she's=she is they're=they

　　are you're=you are there's=there is they're=they are

　　can't=can not don't=do not doesn't=does not

　　isn't=is not aren't=are not let's=let us

　　won't=will not I'll=I will wasn't=was not
