八年級英語語法知識點賓語從句
1.語序
無論主句是陳述句還是疑問句,賓語從句都必須使用陳述語序,即“主句+連詞+賓語從句(主語+謂語+……)”句式。根據連接詞在從句中所擔任的不同成分,可分爲以下四種:
(1)連接詞+謂語。連接詞在從句中作主語。常見的連接詞有: who, what, which等。如:
Could you tell me who knows the answer,please?你能告訴我誰知道答案嗎?
The small children don't know what is in their stockings.這些小孩子不知道襪子裏有什麼東西。
I don't know which belongs to my father.
(2)連接詞+名詞+謂語。連接詞在從句中作主語的定語。常見的連接詞有:whose, what, which, how many, how much等。如:
He asked whose handwriting was the best in our class.他問我們班上誰的書法最好。
The teacher asked us how many people there were in the room.老師問我們房間裏有多少人。
(3)連接詞+主語+謂語。連接詞在從句中作賓語、狀語或表語。常見的連接詞有:who(m), what, which, how many, how much, when, why, how, where, if /whether(在句中不充當任何成分)。如:
He hasn't decided if he'll go on a trip to Wuxi.他還沒決定是否去無錫旅行。
Could you tell me what I should do with the money ?你能告訴我我如何處理這筆錢嗎?
(4)連接詞+名詞+主語+謂語。連接詞在從句中作賓語或表語的定語。常見的連接詞有:what, which, how many, how much, how等。如:
Do you know which class he is in ?你知道他在哪個班嗎?
She asked me if I knew whose pen it was.她問我是否知道這是誰的鋼筆。
2.連接詞
(1)當由陳述句充當賓語從句時,用that引導,that無詞義,在口語或非正式文體中常省略。如:
He said that he could finish his work before supper.他說他會在晚飯前完成工作。
(2)當由一般疑問句充當賓語從句時,用if或whether引導,意爲“是否”。如:
I don't know if /whether he still lives here after so many years.
但在下列情況下只能用whether:
①在具有選擇意義,又有or或or not時,尤其是直接與or not連用時,往往用whether(if…or not也可以使用)。如:
Let me know whether /if he will come or not.(=Let me know whethe or not he will come)
I don't know whether/if he does any washing or not.(=I don't know whether or not he does any washing.)
I wonder whether we stay or whether we go.
②在介詞之後用whether。如:
I'm interested in whether he likes English.我關心的`是他是否喜歡英語。
We're thinking about whether we can finish the work on time.
I worry about whether I hurt her feelings.我擔心是否傷了她的感情。
③在不定式前用whether。如:
He hasn't decided whether to visit the old man.他尚未決定是否拜訪那位老人。
I don't know whether to go.我不知去否。
He hasn't decided whether to go by bus or by train.他還未決定是乘公共汽車去還是坐火車去。
④whether置於句首時,不能換用if。如:
Whether this is true or not, I can't say.這是否真的我說不上來。
⑤引導主語從句和表語從句時宜用whether。如:
Whether she will come or not is still a question.她是否能來還是個問題。
The question is whether we can catch the bus.問題是我們能否趕上公共汽車。
⑥ 若用if會引起歧義時,則用whether。如:
Please let me know if you like the book.可理解爲:a. Please let me know whether you like the book.請告訴我你是否喜歡這本書。B. If you like the book, please let me know.你如果喜歡這本書,請告訴我。
(3)如果賓語從句原來是特殊疑問句,只需用原來的特殊疑問詞引導。如:
Could you tell me why you were late for the meeting this morning?
八年級英語知識重點一、現在分詞的構成的注意要點
1)動詞以單個e 結尾去掉e, 加ing,如:
love _loving
argue _ arguing
2)動詞以 —ee結尾直接加ing,如:
agree_ agreeing
see _ seeing
3)動詞爲單音節:以單一元音字母 + 單一輔音字母結尾輔音字母雙寫,再加ing,如:
hit _ hitting
run _running
4)動詞爲雙音節或者多音節:最後一個音節爲重讀音節,以單一元音字母 + 單一輔音字母結尾輔音字母雙寫,再加ing,如:
begin__ beginning
admit__ admitting
5)以 y 結尾的動詞直接加ing,如:
carry __carrying
enjoy__enjoying
二、現在進行時態的肯定式、否定式、疑問式及簡略回答。
1)肯定式:be+v-ing
She is singing in the next room.
2)否定式:be+not+v-ing
The students aren’t cleaning the room.
3)一般問句:be動詞提前。
肯定答語Yes,主語+be。
否定答語No,主語+be not。
Are you playing the computer game? Yes, I am. /No, I am not.
4)特殊問句:對謂語動詞進行提問的:What+be +主語+doing+其他?
What is the old man doing under the tree?
對其他成份進行提問的,疑問詞+一般疑問句?
