初二英语(宾语从句)

1 Step 1 宾语从句学习 一、宾语从句的断定 定义：宾语从句，顾名思义，是一个用作宾语的句子。例如： I don't know if / whether my father will come back tomorrow. （我不知道明天我爸爸是否会回来。） Tom can't decide which sweater he should buy. （汤姆不能决定应该买哪一件羊毛衫。） We all know（that）the sun rises in the east. （我们都知道太阳在东方升起。） 二、宾语从句应注意三点：连接词、时态、语序 2 .1 连接词 宾语从句的连接词分为三类： 1. 引导陈述句用that（在口语或非正式文体中常常省略）。 2. 引导一般疑问句用if 或whether。 注意：下列几种情况通常使用whether：（1）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；（2）在介词之后用whether；（3）在不定式前用whether 等。 3. 引导特殊疑问句，只需用原来的特殊疑问词。 一Excuse me，could you tell me__________? —There's a bank on the second floor．You can make it there．[黄冈市] A. where I can change money B. how I can get to the bank C. if there's a bank near here D. where the bank is [答案]A． 2 .2 ．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 that Lily was listening to the music. B. Lucy says that Lily will go home. → Lucy said that Lily would go home. C. L...
