我們在學(xué)習(xí)和運(yùn)用賓語從句時(shí)，應(yīng)該注意以下四點(diǎn)：
一、引導(dǎo)詞的使用
1. 當(dāng)賓語從句由陳述句變化而來時(shí)，用that來引導(dǎo)從句，that常無具體意義，一般可省略。例如：
Lin Tao thought（that）the TV play was very boring.
2. 當(dāng)賓語從句是由一般疑問句變化而來時(shí)，要用if或whether來引導(dǎo)從句。例如：
David asked his mother if/ whether she liked the dinner last night.
3. 當(dāng)賓語從句是由特殊疑問句變化而來時(shí)，原句中的疑問詞充當(dāng)連接代詞（如who， whose， what， which）或連接副詞（如when， where， why， how），引導(dǎo)賓語從句。例如：
Do you know what we can do on the island？
I don’t know why Jane was late for school this morning.
二、語序的陳述化
賓語從句一般要用陳述句語序。例如：
When did he leave？ I want to know. →I want to know when he left.
Does the shop close at six every day？ Do you know？ →Do you know if/ whether the shop closes at six every day？
三、時(shí)態(tài)的呼應(yīng)
1. 如果主句是一般現(xiàn)在時(shí)、一般將來時(shí)或祈使句時(shí)，賓語從句可根據(jù)情況使用各種時(shí)態(tài)。例如：
I hear she is here today（she was here yesterday/ she will be here tomorrow.）
2. 如果主句是一般過去時(shí)，賓語從句應(yīng)使用過去時(shí)態(tài)的某種形式。例如：
He said he was watching TV（he had swept the floor/ he would play football after school）。
3. 如賓語從句所敘述的是客觀事實(shí)、自然現(xiàn)象或科學(xué)真理等，從句不受主句時(shí)態(tài)限制，仍用一般現(xiàn)在時(shí)。例如：
Our teacher told us that light travels faster than sound.
四、否定轉(zhuǎn)移
當(dāng)主句的謂語動(dòng)詞為think， believe， suppose等動(dòng)詞，且主語為第一人稱時(shí)，從句的否定要轉(zhuǎn)移到主句上。例如：
I don’t believe he is here on time， is he？
I don’t think Tom is the best student in his class， is he？
