初二英語必備知識點
1. 賓語從句的含義
在主句中做賓語的從句叫做賓語從句。
如：She knew that the teacher had seen the film.
她知道這位老師看過這部電影。
“that the teacher had seen the film”做 knew 的賓語，同時又是由連接詞 that 引導的從句，所以它叫做賓語從句。
2. 賓語從句的分類
(1)動詞賓語從句：顧名思義，它是位于動詞后面的賓語從句。
如：He asked whose handwriting was the best in our class.他問我們班上誰的書法最好。
(2)介詞賓語從句：顧名思義，它是位于介詞后面的賓語從句。
如：I agree with what you said just now.我同意你剛才說的話。
(3)形容詞賓語從句：顧名思義，它是位于形容詞后面的賓語從句。
如：I am afraid that I will be late. 恐怕我要遲到了。
3. 引導名詞性從句的連接詞
(1)that：沒有含義，在賓語從句中不做成分
(2)whether/if：表示是否，在賓語從句中不做成分。
I don't know if /whether he still lives here after so many years. 我不知道這么多年后，他是否還住在這里。
(3)連接代詞：what, which, who, whom, whose(在賓語從句中做主、賓、表和定語)
連接副詞：where, when, how, why(在賓語從句中做狀語)
The small children don't know what is in their stockings.(what 在賓語從句中做主語)
這些小孩子不知道什么在他們的長筒襪里。
Could you tell me why you were late for the meeting this morning?(why 在賓語從句中做原因狀語)
你能告訴我為什么你今天早上開會遲到嗎?
4. 在做賓語從句的題目時應注意兩點
(1)時態：
①當主句是現在時態時，賓語從句可以根據需要使用任何時態。
I don't know when he will come back.我不知道他將何時回來。
He tells me that his sister came back yesterday.他告訴我他姐姐昨天回來了。
②當主句是過去時態時，賓語從句必須是一種過去的時態。
She asked me if I knew whose pen it was.她問我是否知道這是誰的鋼筆。
He said that he could finish his work before supper.他說他會在晚飯前完成工作。
③當表示客觀事實或普遍真理的句子做賓語從句時，任何時候都用一般現在時。
The teacher said that the earth goes round the sun.老師說過地球繞著太陽轉。
