考点精讲
考点01 宾语从句连接词
引导宾语从句的连接词有三种,分别为:
A. 连词 if / whether :原来的直接引语为一般疑问句。
Will he come back tomorrow? Do you know?
→ Do you know if / whether he will come back tomorrow?
B. 连接代词或连接副词:原来的直接引语为特殊疑问句。
Which sweater should Tom buy? Tom can't decide.
→ Tom can't decide which sweater he should buy.
C. 连词 that : 宾语从句是原来直接引语中的陈述句
The sun rises in the east. We all know.
→ We all know (that) the sun rises in the east.
例1: He said ________ she would leave the message on the headmaster's desk.
A. that B. where C. which D. what
例2:A: Could you tell me ________ she is looking for? B: Her cousin, Susan.
A. that B. whose C. who D. which
简析:宾语从句中常有如下三类连接词:
1). 由that 引导的宾语从句。当由陈述句充当宾语从句时,用that引导,that无词义,可以省略。
He said (that ) he could finish his work before supper.他说他会在晚饭前完成工作。
I am glad (that) you have come.我很高兴你来了。
2) . 由if 或whether 引导的宾语从句。当由一般疑问句充当宾语从句时,用if或whether引导,意为“是否”。
I don't know if /whether he still lives here after so many years.我不知道这么多年后他是否还住在这儿。在具有选择意义,又有or或or not时,尤其是直接与or not连用时,往往用whether(if…or not也可以使用)。
Let me know whether /if he will come or not.(=Let me know whether or not he will come)让我知道他是否能来。
I wonder whether we stay or whether we go.我不知道我们是去还是留。
3). 由疑问代词和疑问副词引导的宾语从句。如果宾语从句原来是特殊疑问句,只需用原来的特殊疑问词引导。疑问代词或疑问副词有意义,并在从句中充当一定的句子成分。
Could you tell me why you were late for the meeting this morning?
你能告诉我今天早上你为什么开会迟到吗?
Do you know when we are going to Beijing?
你知道我们什么时候去北京吗?
考点02 宾语从句的时态:
1、如果主句谓语动词为一般现在时,那么宾语从句的谓语动词的时态可以根据具体情况,该用哪种时态,就用哪种时态。
2、如果主句谓语动词的时态为一般过去时,根据主从句时态一致的原则,从句谓语动词的时态可以使用相应的过去时态。
1)宾语从句中的一般现在时变为一般过去时:
is / am / are → was / were; do / does → did; may → might; need → needed can → could .
2)宾语从句中的一般将来时变为过去将来时: is /am / are going to do → was / were going to do; will do → would do .
3)宾语从句中的现在完成时变为过去完成时: has / have done → had done .
4)宾语从句中的现在进行时变为过去进行时: is / am / are doing → was / were doing .
A. Lucy says that Lily is listening to the music.
→ Lucy said t
