英語(yǔ)語(yǔ)法：名詞性從句學(xué)習(xí)中的易錯(cuò)點(diǎn)總結(jié)

字號(hào)： 小 中 大

由一個(gè)主句和一個(gè)或一個(gè)以上的從句構(gòu)成的句子叫復(fù)合句。在復(fù)合句中主句是全句的主體，從句是全句的一個(gè)成分，不能獨(dú)立。從句通常是用關(guān)聯(lián)詞來(lái)引導(dǎo)的。在這里關(guān)聯(lián)詞還起聯(lián)系從句和主句的作用。下面是整理發(fā)布的名詞性從句學(xué)習(xí)中的易錯(cuò)點(diǎn)總結(jié)，歡迎閱讀參考！更多相關(guān)訊息請(qǐng)關(guān)注！
    

    一、從句的種類：
    

         主語(yǔ)從句、賓語(yǔ)從句、表語(yǔ)從句、同位語(yǔ)從句，定語(yǔ)從句和狀語(yǔ)從句
    

    二、名詞性從句的連接詞
    

    1. 單純連詞
    

    在從句中不補(bǔ)充當(dāng)任何成分，只起到連接從句的功能。
    

    that 沒(méi)有實(shí)際意義，而whether/ if 在句子中表示“是否” 的意義。
    

    Eg : That the prices of rice will go up is certain. (that引導(dǎo)主語(yǔ)從句，補(bǔ)充當(dāng)任何成分)
    

           He asked if I could come to see him this weekend.
    

         形式主語(yǔ)it 代替主語(yǔ)從句位于句首時(shí)，常見(jiàn)的幾種情況：
    
         ① It + adj +that 從句(大多數(shù)情況下that從句后用should+動(dòng)詞原形)
    

          Adj: necessary  right  clear  unlikely  strange  obvious  natural  important
    

          Eg: It is necessary to learn English well.
    

          ② It +系動(dòng)詞+名詞+that 從句
    

          Non: a pity  an honor  good news  a wonder  a fact  no wonder  no surpeise
    

          Eg: It is a fact that you are a good boy.
    

          ③ It +be + 過(guò)去分詞+that從句
    

          過(guò)去分詞：said / heard/ reported/ told/ decided/suggested/thought/considered/ hoped/ announced 
    

          Eg: It is announced that the plan has been canceled.
    

         注意：
         It + be+ suggested/ advised/ ordered/ requested/ insisted/ demand+ that從句， that從句要用should +動(dòng)詞原形，should可以省略。
    

         Eg: It is suggested that you (should ) spend more time in studying English .
    

         當(dāng)suggest表示“表明”時(shí)，不可以用虛擬語(yǔ)氣
    

         Eg: It suggests that you are an honest boy.
    

         Insist 表示“堅(jiān)持某種說(shuō)法（事情已經(jīng)發(fā)生過(guò)了）”，不用虛擬語(yǔ)氣。
    

         表示“堅(jiān)持要做（事情沒(méi)有發(fā)生）”，要用虛擬語(yǔ)氣。
    

         Eg: she insisted that I have never done such thing .
    

               She insisted that I study abroad.
    

         ④It +動(dòng)詞（+賓語(yǔ)或狀語(yǔ)）+that 從句
    

         動(dòng)詞如： appear(顯得)/ happen(碰巧)/ matter(重要)/ occur(出現(xiàn))/ turn out(結(jié)果是)
    

         Eg: It happened to me that I was away when he came.主語(yǔ)從句不可位于句首的五種情況：
    

         注意：
         （1）if 引導(dǎo)的主語(yǔ)從句不可居于復(fù)合句句首。
    

         （2）It is said /reported?結(jié)構(gòu)中的主語(yǔ)從句不可提前。
    

           正確表達(dá)：It is said that President Jiang will visit our school next week.
    

           錯(cuò)誤表達(dá)：That President Jiang will visit our school next week is said.
    

         （3）It happens/occurs?結(jié)構(gòu)中的主語(yǔ)從句不可提前。
    

           正確表達(dá)：It occurred to him that he failed in the examination.
    

          錯(cuò)誤表達(dá)：That he failed in the examination occurred to him.
    

         （4）It doesn’t matter how/whether ?結(jié)構(gòu)中的主語(yǔ)從句不可提前。
    

           正確表達(dá)：It doesn’t matter whether he is wrong or not.
    

           錯(cuò)誤表達(dá)：Whether he is wrong or not doesn’t matter.
    

         （5）含主語(yǔ)從句的復(fù)合句是疑問(wèn)句時(shí)，主語(yǔ)從句不可提前。
    

           正確表達(dá)：Is it likely that it will rain in the evening?
    

          錯(cuò)誤表達(dá)：Is that will rain in the evening likely?
