區(qū)分賓語(yǔ)從句、定于從句和狀語(yǔ)從句賓語(yǔ)從句和狀語(yǔ)從句，都叫做主從復(fù)合句。賓語(yǔ)從句主要是中考必考的，是初中階段必掌握的從句，賓語(yǔ)從句主要是掌握三要素，所謂賓語(yǔ)從句，就是賓語(yǔ)在主從復(fù)合句當(dāng)中充當(dāng)賓語(yǔ)的一個(gè)句子，叫做賓語(yǔ)從句。主句的謂語(yǔ)動(dòng)詞是及物動(dòng)詞，后面如果是詞或者是短語(yǔ)的話，是簡(jiǎn)單句，如果是句子的話，肯定是賓語(yǔ)從句。I know that he good at English.就是賓語(yǔ)從句，三要素，一要素是要注意連詞，連詞一共學(xué)了三類連詞，一類連詞是that口語(yǔ)當(dāng)中可以省略，就像剛才說(shuō)的那一句，I hear he is good at English.還有疑問(wèn)代詞、疑問(wèn)副詞，how where when，疑問(wèn)代詞、疑問(wèn)副詞。還有一類連詞weather是否的意思，不是狀語(yǔ)從句當(dāng)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(yǔ)從句要注意if是連詞。第二要素是語(yǔ)序，要用陳述舉語(yǔ)序。比如說(shuō)你家有幾口人，我們都說(shuō)How many people are there in you family?但是這是簡(jiǎn)單句，一旦說(shuō)成賓語(yǔ)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 ?
