點(diǎn)總結(jié)
在句子中起賓語作用的從句叫做賓語從句。賓語從句要抓住三要素:引導(dǎo)詞、語序和時(shí)態(tài)。
一、.引導(dǎo)詞
1.從句為陳述句,常選擇引導(dǎo)詞that,that引導(dǎo)賓語從句無意義,不充當(dāng)句子成分常省略。例句:He told us (that) they would help us through the whole work.
2.從句為一般疑問句,常選擇引導(dǎo)詞if或whether,表示“是否”。在 whether … or not 結(jié)構(gòu)中不能用 if 替換。例句:I don’t know if there will be a bus any more.
3. 從句為特殊疑問句,常選擇what,when,where,which,who,how等的疑問代詞、副詞作引導(dǎo)詞。 例句:He didn’t tell me when we should meet again.
二、判斷時(shí)態(tài)情況:
1.主句是一般現(xiàn)在時(shí),從句可以為各種時(shí)態(tài)。   
2.主句是一般過去時(shí),從句要用相應(yīng)過去時(shí)態(tài)。
注意:從句描繪客觀事實(shí)、真理、自然現(xiàn)象等,從句時(shí)態(tài)不受主句時(shí)態(tài)限制,仍用一般現(xiàn)在時(shí)。
例句:He answered that he was listening to me.
Father told me that practice makes perfect .
三、賓語從句的語序要用陳述句語序
陳述句語序,就是主語在前,謂語動(dòng)詞在后。  
錯(cuò)誤: He is wondering when can he finish this difficult job.  
正確: He is wondering when he can finish this difficult job.
注意:賓語從句的否定轉(zhuǎn)移
主句的謂語動(dòng)詞是think,believe,imagine,suppose,consider,expect,fancy,guess等,并且主句的主語是第一人稱而且為一般現(xiàn)在時(shí),從句的否定詞一般要轉(zhuǎn)移到主句上來,其反義疑問句一般與賓語從句一致.  例如; I don’t think he will come to my party.而不能說成I think he won’t come to my party.
常見考法
對(duì)于賓語從句的考查,多以單選的形式考查靈活運(yùn)用的。一般情況下,常從引導(dǎo)詞的選擇、時(shí)態(tài)的一致性及從句的陳述語序方面考查。
典型例題:Please tell me ______ last year.
A.where does your sister work B where did your sister work
C .where your sister works D where your sister worked
解析:本題考查對(duì)賓語從句的掌握。賓語從句要用陳述語序,所以排除A和 B;last year 表示過去時(shí) ,所以排除 C 。
答案:D
誤區(qū)提醒
賓語從句的語序要用陳述句語序 ,但要注意當(dāng)疑問詞為主語時(shí),句式為:疑問詞+謂語+其他 ,問句和陳述句語序一樣。
典型例題:I didn't know ?
A. What wrong was with her B.what was wrong with her
C .what wrong is with her D.what is wrong with her
解析:主句是一般過去時(shí),從句要用相應(yīng)過去時(shí)態(tài),所以排除C和D;在what was wrong with her中,what作主語,所以問句本身又是陳述句語序,不用變化。
答案: B
