八年級上冊英語語法 必背知識點(diǎn)匯總

八年級學(xué)生學(xué)習(xí)英語需要掌握的語法相對多一點(diǎn)，下面初三網(wǎng)小編為大家總結(jié)了八年級上冊英語語法，僅供大家參考。

初二英語語法知識

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。

八年級必背的英語知識點(diǎn)

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.

英語if引導(dǎo)的英語知識點(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.
