中考英語難點(diǎn)語法詳解
在初中英語教學(xué)中,語法的學(xué)習(xí)屬于初級階段,對以后系統(tǒng)學(xué)習(xí)英語至關(guān)重要。接下來學(xué)習(xí)啦小編為你整理了中考英語難點(diǎn)語法詳解,一起來看看吧。
中考英語難點(diǎn)語法詳解:what的三種用法
引導(dǎo)名詞性從句的what在從句中作主語、賓語、表語或定語。
(1)具有疑問代詞性質(zhì)的what:意為“什么,什么樣的”。如:
I don’t know what he needs. 我不知道他需要什么。(what在賓語從句中作賓語)
(2)在名詞前表示感嘆的what:意為“多么”。如:
Only then did I recognize what silly mistakes I had made. 只是在那時(shí)我才意識到我犯了多么愚蠢的錯(cuò)誤。(what在賓語從句中作定語)
(3)具有關(guān)系代詞性質(zhì)的what:意為“所……的”。
相當(dāng)于“the+名詞+that”或者all that,即好像是既包括了先行詞也包含了關(guān)系代詞,因此,有學(xué)者稱之為關(guān)系代詞型what。如:
What (=The thing that) happened after that was interesting. 后來發(fā)生的事挺有意思。(what在主語從句中作主語)
China is not what (=the China that) used to be. (what在表語從句中作表語)
The boy dived into water and after what (the time that) seemed to be a long time, he came up again. 他跳進(jìn)水里,過了好像很久之后,他才又從水里出來。(what在賓語從句中作主語)
中考英語難點(diǎn)語法詳解:since和for
Since 用來說明動(dòng)作起始時(shí)間,for用來說明動(dòng)作延續(xù)時(shí)間長度。例如:
I have lived here for more than twenty years.我住在這兒二十多年了。
I have lived here since I was born. 我從出生起就住在這兒了。
注意:并非有for 作為時(shí)間狀語的句子都用現(xiàn)在完成時(shí)。
I worked here for more than twenty years. (我現(xiàn)在已不在這里工作。)
I have worked here for many years.(現(xiàn)在我仍在這里工作。)
注意:用句型轉(zhuǎn)換的方法,很容易排除非延續(xù)動(dòng)詞在有for/since結(jié)構(gòu)的完成時(shí)中的誤用。
(1)(對)Tom has studied Russian for three years. = Tom began to study Russian three years ago, and is still studying it now.
(2)(錯(cuò))Harry has got married for six years. = Harry began to get married six years ago, and is still getting married now.
顯然,第二句不對,它應(yīng)改為 Harry got married six years ago. 或 Harry has been married for six years.
中考英語難點(diǎn)語法詳解:will與would的區(qū)別
1.表示意愿時(shí)的區(qū)別
will 表示現(xiàn)在的意愿,would 表示過去的意愿:
Go where you will. 你愿到哪里就到哪里。
She asked if I would go with them. 她問我是否愿意同他們一起去。
2.表示征求意見或提出請求的區(qū)別
主要用于第二人稱的疑問句中,will 和 would 均可用,would 此時(shí)并不表示過去,而表示委婉語氣:
Won’t you take off your coat? 你要不要把大衣脫掉?
Will you please post the letter for me? 請幫我寄了這封信好嗎?
3.表示習(xí)慣和傾向性的區(qū)別
will 表示現(xiàn)在的習(xí)慣,would 表示過去的習(xí)慣:
This window won’t open. 這扇窗戶經(jīng)常打不開。
When he was a child, he would often go skating. 他小時(shí)候經(jīng)常去滑冰。
would like / would love可視為習(xí)語,意為“想要”,其后接名詞、代詞或不定式:
I would like a cup of tea. 我想要杯茶。
We would love to go with him. 我們想同他一起去。
