　　賓語(yǔ)從句的意義

　　賓語(yǔ)從句在復(fù)合句中作主句的賓語(yǔ)。賓語(yǔ)從句通常由連詞(that， whether， if)、連接代詞(which， what， who， whose， whom)或連接副詞(where， how， when， why)等引導(dǎo)。及物動(dòng)詞、介詞或某些系表結(jié)構(gòu)后可帶賓語(yǔ)從句。

　　句型結(jié)構(gòu)：主語(yǔ)+謂語(yǔ)+引導(dǎo)詞+主語(yǔ)+謂語(yǔ)(+其他成分)

　　賓語(yǔ)從句時(shí)態(tài)

　　主句是一般現(xiàn)在時(shí)，從句根據(jù)實(shí)際情況使用任何時(shí)態(tài)。

　　主句是一般過(guò)去時(shí)，從句須用過(guò)去時(shí)態(tài)的某種形式。
