我們在學習和運用賓語從句時，應該注意以下四點：
    一、引導詞的使用
    1. 當賓語從句由陳述句變化而來時，用that來引導從句，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. 當賓語從句是由一般疑問句變化而來時，要用if或whether來引導從句。例如：
    David asked his mother if/ whether she liked the dinner last night.
    3. 當賓語從句是由特殊疑問句變化而來時，原句中的疑問詞充當連接代詞（如who， whose， what， which）或連接副詞（如when， where， why， how），引導賓語從句。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、時態(tài)的呼應
    1. 如果主句是一般現(xiàn)在時、一般將來時或祈使句時，賓語從句可根據(jù)情況使用各種時態(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，賓語從句應使用過去時態(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、自然現(xiàn)象或科學真理等，從句不受主句時態(tài)限制，仍用一般現(xiàn)在時。例如：
    Our teacher told us that light travels faster than sound.
    四、否定轉移
    當主句的謂語動詞為think， believe， suppose等動詞，且主語為第一人稱時，從句的否定要轉移到主句上。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？
