  原标题:复合句之宾语从句考点大观

  从句做宾语的复合句叫宾语从句,有关宾语从句的考点多集中在以下五个方面:

  注意使用正确的引导词

  (1)当宾语从句由陈述句变化而来时,用that引导从句,其中that并无具体意义,可以省略

  He said (that) the bank was near the hotel.

  他说银行就在宾馆附近.

  (2)当宾语从句由一般疑问句变化而来时,可用if 或whether 来引导,意为是否.

  She asked me if(whether)she could join us.

  她问我是否可以加入我们的队伍.

  (3)当宾语从句由特殊疑问句变化而来时, 特殊疑问词就是从句的引导词,如who, whose, what, which, when, where, why, how等

  Do you know who broke the door?

  你知道谁弄坏了门吗?

  Can you tell me where the bank is?

  你能告诉我银行在哪吗?

  注意使用陈述语序

  所有的宾语从句都要使用陈述语序,如:

  When did the train leave? I want to know.变为I want to know when the train left.

  我想知道火车什么时候离开的.

  Do they often play basketball? He asked. 变为 He asked if they often played basketball.

  他问他们是否经常打篮球.

  注意正确使用时态

  (1)如果主句是一般现在时,一般将来时或祈使句时,宾语从句时态不受限制,根据实际表达需求来确定.

  He will tell us that he has been able to look after himself.

  他将告诉我们他已经能照顾自己.

  告诉他我们将什么时候出发.

  (2)如果主句是一般过去时,从句必须是过去的某种时态.

  He said that he was born in Beijing in 1985.

  他说他1985年出生在北京.

  (3)如果从句陈述的是客观事实,真理时,时态也要用一般现在时.

  He said that light travels faster than sound.

  他说光比声音传播的快.

  否定前移的问题

  在宾语从句中,当主句的谓语是think, believe, imagine, expect, suppose等时,且主语为I ,we时,从句中表示否定意义的not 要移到think, believe, imagine, expect, suppose前面.

  I don’t think he is right.

  我认为他不对.

  注意:如果主语不是I ,we,则not 不前移.

  She thinks her answer isn’t right.

  她认为她的答案不正确.

  只能用whether不能用if 的情况

  if和whether在引导宾语从句时,一般可以交换使用,但在以下5中情况中只能用whether不能用if.

  (1)引导主语从句时

  Whether he will help us is doubtful.

  他是否会帮助我们仍有疑问.

  (2)引导表语或同位语从句时

  The problem is whether we will start soon.

  问题是我们是否一会儿出发.

  (3)用在介词后时

  Everything is depends on whether it is fine tomorrow.

  所有的事都取决于明天天气是否晴朗.

  (4)与or not 连用时

  I asked him whether he knew the answer or not.

  我问他是否知道答案.

  (5)在动词不定式之前

  She doesn’t know whether to leave or stay.

  她不知道是走还是留.
