19、从句中不作句子成分,也无词汇意义,在口语中或非正式文体中常被省略。例如: He knew(that)he should work hard. .连词whether或if:它们起连接作用,在从句中不作句子成分,作是否解,口语中多用if。例如: Do you know whether he will ride here at 8 tomorrow morning? .连接代词who,whom ,whose,what, which:它们起连接作用,作句子成分,各有其自己的意义。例如: The teacher asked the new student which class he was in? .

20、连接副词when,where, why,how:起连接作用,分别作时间、地点、原因、方式状语,各有其自己的意义。例如: I wonder where he got so much money.对他从哪里弄到那么多钱我感到疑惑。(where在从句中作地点状语,修饰got,意为哪里;什么地方。) 第二,牢记宾语从句的语序是陈述句语序,即连接词+主语+谓语+其他。这里特别强调的是,它的主语和谓语的语序是陈述句的语序,不是疑问句的倒装语序。 例如:You must remember what your teacher said. 第三,注意时态的呼应。 宾语从句中谓语动词的时态,常常受主句谓语时态的制

21、约,这种现象称为时态的呼应。 例如: 汉译英:我原以为你今天有空的。 误:I thought(that)you are free today. 正:I thought(that)you would be free today. 错句中宾语从句用are很可能是因为有 today,但因为主句谓语是thought,所以从句谓语就该用过去将来时would be了。 这种时态的呼应,如果主句谓语是现在时或将来时,宾语从句的谓语时态不受限制. 另外,如果主句时态是过去时,宾语从句一般要随着改为相应的过去时(即一般过去时、过去进行时、过去完成时、过去将来时等)。中考真题全解 1-Why does Peter
