　　一、定義

　　賓語(yǔ)從句就是一個(gè)句子的賓語(yǔ)部分是由另一個(gè)句子來充當(dāng)。賓語(yǔ)從句需要用引導(dǎo)詞來引導(dǎo)。學(xué)好賓語(yǔ)從句，必須過“三關(guān)”。即引導(dǎo)詞關(guān)、語(yǔ)序關(guān)、時(shí)態(tài)關(guān)。

　　二、引導(dǎo)詞關(guān)

　　引導(dǎo)賓語(yǔ)從句的引導(dǎo)詞分為三類，即:

　　1)。That在從句中不充當(dāng)任何成分，也無實(shí)義，只是起到連接的作用。

　　通常在say, think, wish , hope, see, believe, agree, expect, hear , feel等動(dòng)詞后加that，引導(dǎo)賓語(yǔ)從句。連詞that在口語(yǔ)中常被省略。󰀀

　　如：He said that he was a student.

　　I thought that he was wrong.󰀀

　　☆注意：A) 引導(dǎo)賓語(yǔ)從句的that ?？梢允÷?但下列情況下不能省略。

　　(1)and連接兩個(gè)或兩個(gè)以上的賓語(yǔ)從句，除第一個(gè)從句中的that以外,后面從句中的 that不能省略。

　　如：I know (that) he is a good student and that he likes basketball.

　　(2)、that引導(dǎo)的賓語(yǔ)從句作介詞賓語(yǔ)時(shí)，that不能省略。

　　如： I know nothing about him except that he is from the south.

　　(3)、主句謂語(yǔ)動(dòng)詞與that從句之間有插入語(yǔ)，that不可省略。

　　如：We decided, considering his age, that we would not let him do the job.

　　B) 常這樣用的動(dòng)詞有find,feel,consider,make,believe 等。

　　如：He doesn’t want it to be known that he is going away.

　　C) think, believe, imagine, suppose, consider, expect, fancy,guess等表示主觀看法或認(rèn)識(shí)的動(dòng)詞,.

　　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.) I don’t believe that he is a good student, is he? 我認(rèn)為他不是個(gè)好學(xué)生，不是嗎? I don’t think you are right.

　　I don’t believe that they have finished their work.

　　比較：she believes that I am not a good student.

　　2)?？梢曰Q。

　　如：I don't know whether/if I should go to the party tomorrow.

　　注意：在以下情況中，只能用whether。

　　I will give you whatever you want.

　　You can meet whoever you want to see.

　　I told him where he should go.

　　I don't know why he is so angry.

　　You can come whenever you are free.

　　4)另外：賓語(yǔ)從句可做動(dòng)詞賓語(yǔ),介詞賓語(yǔ),及某些形容詞甚至是副詞的賓語(yǔ). 例如：

　　1、He said that he was a student.(that從句是said的賓語(yǔ))

　　2、賓語(yǔ)從句作介詞的賓語(yǔ)，常常有兩種情況：

　　B)用that,whether引導(dǎo)的介詞賓語(yǔ)從句
