區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句，都叫做主從復合句。賓語從句主要是中考必考的，是初中階段必掌握的從句，賓語從句主要是掌握三要素，所謂賓語從句，就是賓語在主從復合句當中充當賓語的一個句子，叫做賓語從句。主句的謂語動詞是及物動詞，后面如果是詞或者是短語的話，是簡單句，如果是句子的話，肯定是賓語從句。I know that he good at English.就是賓語從句，三要素，一要素是要注意連詞，連詞一共學了三類連詞，一類連詞是that口語當中可以省略，就像剛才說的那一句，I hear he is good at English.還有疑問代詞、疑問副詞，how where when，疑問代詞、疑問副詞。還有一類連詞weather是否的意思，不是狀語從句當中的如果，這一定要和如果區(qū)分開，這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序，要用陳述舉語序。比如說你家有幾口人，我們都說How many people are there in you family?但是這是簡單句，一旦說成賓語從句，你可以告訴我你家有幾口人嗎？Could you tell me how many people there are in you family ?
