八年級(jí)英語(yǔ)重要知識(shí)點(diǎn)
一般疑問(wèn)句
一、不用疑問(wèn)詞,但需要用yes或no回答的疑問(wèn)句,叫一般疑問(wèn)句。句末用問(wèn)號(hào)“?”。
一般疑問(wèn)句的基本用法及結(jié)構(gòu)一般疑問(wèn)句用于對(duì)某一情況提出疑問(wèn),通??捎脃es和no來(lái)回答,讀時(shí)用升調(diào)。其基本結(jié)構(gòu)是“be / have / 助動(dòng)詞+主語(yǔ)+謂語(yǔ)(表語(yǔ))”:
Is he interested in going? 他有興趣去嗎?
Have you ever been to Japan? 你到過(guò)日本嗎?
Does she often have colds? 她常常感冒嗎?
Did you ask her which to buy? 你問(wèn)沒(méi)問(wèn)她該買(mǎi)哪一個(gè)?
二、陳述句變一般疑問(wèn)句的方法
1.動(dòng)詞be的疑問(wèn)式:動(dòng)詞be根據(jù)不同的時(shí)態(tài)和人稱(chēng)可以有am, is, are, was, were等不同形式,可用作連系動(dòng)詞(表示“是”、“在”等)和助動(dòng)詞(用于構(gòu)成進(jìn)行時(shí)態(tài)和被動(dòng)語(yǔ)態(tài)等),但不管何種情況,構(gòu)成疑問(wèn)式時(shí),一律將動(dòng)詞be的適當(dāng)形式置于句首:句型:Be動(dòng)詞+主語(yǔ)~?
Is your father angry?你父親生氣了嗎?
Yes,he is.是的,他生氣了。
No,he isn't.不,他沒(méi)生氣。
Were the babies crying last night?(進(jìn)行時(shí))
昨天晚上這些孩子們一直在哭嗎?
Yes,they were.是的,他們?cè)诳蕖?/p>
No,they weren't.不,他們沒(méi)哭。
Is English spoken all over the world?(被動(dòng)語(yǔ)態(tài))
全世界都說(shuō)英語(yǔ)嗎?
Yes,it is.是的。

初二期末英語(yǔ)語(yǔ)法知識(shí)點(diǎn)總結(jié)歸納
1.由that引導(dǎo),由于that沒(méi)有任何意義,也不充當(dāng)任何句子成分。因此that在非正式文體中可以省略。這類(lèi)賓語(yǔ)從句通常表達(dá)一種陳述意義。
e.g.He told me (that) he would go to Wuhan.
Tom says (that) he must study hard.
She told me (that) she was a student.
(1)如果由and連接兩個(gè)并列的賓語(yǔ)從句時(shí),第二個(gè)that則不能省略。
e.g.She said she liked English very much and that she didn’t like math at all.
(2)常接that引導(dǎo)的賓語(yǔ)從句的謂語(yǔ)動(dòng)詞有:believe, expect, explain, feel, hear, hope, imagine, prefer, promise, report, say, see, tell, think, understand, warn, wish等。
2.由連接代詞或連接副詞who, whose, what, which, when, where, how, why引導(dǎo),含有“誰(shuí)、什么、哪個(gè)、什么時(shí)候、什么地方、怎樣、為什么”等特殊疑問(wèn)意義。
e.g.Do you know who they’re talking about?
Can you tell me what they’re looking for?
I don’t know where she has gone.
I wonder how she can find us.
She didn’t tell me where her hometown was.
3.由從屬連詞whether和if引導(dǎo),含有“是否,能否,對(duì)否,有否”等一般疑問(wèn)意義。
e.g.She asked me if I could help her.
Jim wanted to know whether I had taken his English book.
Please tell me whether you can come or not.
在這類(lèi)賓語(yǔ)從句中要注意兩點(diǎn):
(1)if引導(dǎo)賓語(yǔ)從句和狀語(yǔ)從句的區(qū)別
if引導(dǎo)賓語(yǔ)從句時(shí)意為“是否”,從句中該用什么時(shí)態(tài)就應(yīng)用什么時(shí)態(tài)。
if引導(dǎo)條件狀語(yǔ)從句時(shí)意為“假如”,從句中應(yīng)用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí)。
e.g.She wanted to know if you were a teacher.
I don’t know if the letter is yours.
They’ll go boating if it is fine tomorrow.
I’ll give it to her if she comes next week.
(2)if引導(dǎo)賓語(yǔ)從句時(shí)多數(shù)情況下可以與whether互換,但如果要突出“究竟是……還是不……”這層意思時(shí),通常用whether,并在后面的加上“or not”,即一般要選擇whether構(gòu)成whether…or not的結(jié)構(gòu)。
e.g.Please find out whether the money is his or not.
Let me know whether you can come or not.
I want to know whether you can help me or not.
