概念: 置于動詞、介詞等詞性后面，在句子中起賓語作用的從句叫做賓語從句供屉。
賓語從句分為三類:
動詞的賓語從句、介詞的賓語從句溺蕉、形容詞的賓語從句
賓語從句的語序必須是陳述語序伶丐，
謂語動詞、介詞疯特、動詞不定式哗魂、v.-ing 形式后面都能帶賓語從句，
有些形容詞(afraid漓雅，sure录别， glad 等)之后也可以帶賓語從句。
構成：【主語 + 謂語 + 引導詞 + 句子】
He suggested that we should leave the hotel.
他建議我們應該馬上離開賓館邻吞。
引導詞
that, whether, if, what, who, which, whose, whoever, whatever, whichever, when, where, why, how 與主語從句基本相同
高頻考點:連接詞 時態(tài) 語序
連接詞
- that 沒有實際意義组题，只做連接使用；兩上以上 that 賓從抱冷，第一個可省略崔列，后面不可省；
He said (that) the film was interesting and that he enjoyed seeing it.
- what, who, whose, which, whom 等連接代詞,主語赵讯、賓語盈咳、定語.
I don' t know what they are going to do.
I don' t know who stole the money.
I don' t know whom you are taking care of.
- when， where边翼， why鱼响， how 連接副詞，時問狀語组底、地點狀語丈积、原因狀語、方式狀語债鸡。
I don' t know when he leaves.
I don't know where he goes.
I don't know why he leaves.
I don't know how he finds her.
- If/whether 連接副詞 “是否” whether 可以與 not 連用桶癣，但 if 不可以
He asked me if Miss Gao was a teacher.
He asked me whether Miss Gao was a teacher.
He asked me whether Miss Gao was a teacher or not.
I don’t know if/whether it will rain tomorrow.
時態(tài)
- 主現(xiàn)，從隨便娘锁；主句是(一般現(xiàn)在牙寞、現(xiàn)在進行、現(xiàn)在完成)莫秆，從句可任選時態(tài)
I remember he gave me a book yesterday.
I remember he has given me the book.
I remember he will leave tomorrow.
- 主過去间雀，從過去：主句是過去的某種時態(tài)(一般過去、過去進行镊屎、過去完成惹挟、過去將來)，從句也用過去的時態(tài)缝驳。
He told me that he would take part in the competition.
He told me that he had finished his homework.
- 客觀真理很一般:從句是客觀真理连锯，不受主句影響，永遠用一般現(xiàn)在時用狱。
He told me that the earth is round
The teacher will tell us why light travels faster than sound.
語序
- 從句一定要使用陳述句語序
陳述句語序：引導詞 + 主 + 謂
I don’t know what he eats.
I don’t know where he eats.
I don’t know when he eats.
I don’t know why he eats.
I don’t know if he eats.
- 主語是第一人稱运怖，謂語是
think、believe夏伊、suppose時摇展，從句的否定要放在主句中。
I don’t think you are right
I don’t believe he will come.
如何辨別使用哪個引導詞溺忧，句子中缺失哪個含義就用哪個詞咏连，沒有含義用 that
形式賓語在賓語從句中的使用:
通常說來,當主句有賓語補足語,同時句子的賓語又是一個從句時, 這時,通常采用 it 做形式賓語,而真正的賓語則放在句子的結尾。
我認為你好好學英語是必要的鲁森。
I think it necessary that you should study English hard.
完成時:
- 現(xiàn)在完成時——過去發(fā)生的動作祟滴，一直持續(xù)到現(xiàn)在，或對現(xiàn)在還有影響歌溉。
It has rained for half a year. (雨從過去開始下垄懂，一直持續(xù)到現(xiàn)在，所以用現(xiàn)在完成時)
時間狀語:already、yet埠偿、just、never榜晦、ever冠蒋、before、since乾胶、up to now - 過去完成時——在過去某個點以前就已經發(fā)生的動作抖剿，即“過去的過去”完成的動作。
When he got there, the train had left. (火車離開识窿，是在他到的那個時刻以前發(fā)生的斩郎，同時火車離開是 一個持續(xù)性的過程，所以用過去完成時)
時間狀語:by the time/end of +過去時間;
when/before/after+過去時間 - 將來完成時——在將來某個點以前就發(fā)生的動作喻频。
When we get there tomorrow, the train will have left. (火車離開缩宜，是在明天到來以前發(fā)生的，同時火 車離開時一個持續(xù)性的過程甥温，所以用將來完成時)
時間狀語:by the time/end of +將來時間; when/before/after+將來時間
例句:You will have reached Shanghai by this time tomorrow.
表語從句
謂語動詞是系動詞時锻煌。Be 動詞,部分感官動詞 hear, look, sound 等,一些其他動詞 appear, remain prove 等
引導詞：與主語從句基本相同
差異：
- 不能有 if
- 除了引導主語從句的那些引導詞之外,表語從句還可以用 as if(好似), as though(好像), because 來引導
我的決定是所有人都在明天七點離開賓館。
My decision is that all the people should leave the hotel at 7:00 tomorrow.
