八年級英語重要知識點(diǎn)
一般疑問句
一、不用疑問詞，但需要用yes或no回答的疑問句，叫一般疑問句。句末用問號“?”。
一般疑問句的基本用法及結(jié)構(gòu)一般疑問句用于對某一情況提出疑問，通?？捎脃es和no來回答，讀時用升調(diào)。其基本結(jié)構(gòu)是“be / have / 助動詞+主語+謂語(表語)”：
Is he interested in going? 他有興趣去嗎?
Have you ever been to Japan? 你到過日本嗎?
Does she often have colds? 她常常感冒嗎?
Did you ask her which to buy? 你問沒問她該買哪一個?
二、陳述句變一般疑問句的方法
1.動詞be的疑問式：動詞be根據(jù)不同的時態(tài)和人稱可以有am， is， are， was， were等不同形式，可用作連系動詞(表示“是”、“在”等)和助動詞(用于構(gòu)成進(jìn)行時態(tài)和被動語態(tài)等)，但不管何種情況，構(gòu)成疑問式時，一律將動詞be的適當(dāng)形式置于句首：句型：Be動詞+主語～?
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，他沒生氣。
Were the babies crying last night?(進(jìn)行時)
昨天晚上這些孩子們一直在哭嗎?
Yes，they were.是的，他們在哭。
No，they weren't.不，他們沒哭。
Is English spoken all over the world?(被動語態(tài))
全世界都說英語嗎?
Yes，it is.是的。
No，it isn't.不。

初二期末英語語法知識點(diǎn)總結(jié)歸納
1.由that引導(dǎo)，由于that沒有任何意義，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。這類賓語從句通常表達(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連接兩個并列的賓語從句時，第二個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)的賓語從句的謂語動詞有：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、什么、哪個、什么時候、什么地方、怎樣、為什么”等特殊疑問意義。
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，對否，有否”等一般疑問意義。
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.
在這類賓語從句中要注意兩點(diǎn)：
(1)if引導(dǎo)賓語從句和狀語從句的區(qū)別
if引導(dǎo)賓語從句時意為“是否”，從句中該用什么時態(tài)就應(yīng)用什么時態(tài)。
if引導(dǎo)條件狀語從句時意為“假如”，從句中應(yīng)用一般現(xiàn)在時代替一般將來時。
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)賓語從句時多數(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，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.
