宁波英语口语培训班哪家好

宾语从句是初中阶段英语教学的，学生学习的难点。是在平时测试，在竞赛或中考中，牵涉到宾语从句用法的试题，所占的分值也比。现将初中阶段涉及到的宾语从句归纳如下，供同学们学习时参考。

一 . 宾语从句的判断

宾语从句，顾名思义，是用作宾语的句子。例如：

I don't know if / whether my father will come back tomorrow.

（我不知道明天我爸爸会回来。）

Tom can't decide which sweater he should buy. （汤姆决定应该买哪一件羊毛衫。）

We all know （ that ） the sun rises in the east. （都知道太阳在东方升起。）

二 . 辨别主句和宾语从句

引导宾语从句的连接词有三种，分别为： A. 连词 if / whether ； B. 连接代词或连接副词； C. 连词 that .原来的直接引语为疑问句，变成间接引语时，就了 A 种宾语从句。原来的直接引语为特殊疑问句，变成间接引语时，就了 B 种宾语从句。 C 种宾语从句是原来直接引语中的陈述句。如将两个句子组成含有宾语从句的主从复合句，会有几种情况：

1. Will he come back tomorrow？ Do you know？

→ Do you know if / whether he will come back tomorrow？

2. Which sweater should Tom buy？ Tom can't decide.

→ Tom can't decide which sweater he should buy.

3. The sun rises in the east. We all know.

→ We all know that the sun rises in the east.

三 . 当主句的谓语动词为现在时时，从句中的谓语动词的时态

主句谓语动词为现在时，那么宾语从句的谓语动词的时态可以情况，该用哪种时态，就用哪种时态。

主句谓语动词的时态为时，主从句时态的原则，从句谓语动词的时态可以使用的时态。如宾语从句中的现在时变为时： is / am / are → was / were； do / does → did； may → might； need → needed can → could .将来时变为将来时： is /am / are going to do → was / were going to do； will do → would do .现在时变为时： has / have done → had done .现在时变为时： is / am / are doing → was / were doing .

请看下列句子：

Lucy says that Lily is listening to the music. → Lucy said that Lily was listening to the music.

Lucy says that Lily will go home. → Lucy said that Lily would go home.

Lucy says that Lily gets up at five. → Lucy said that Lily got up at five.

Lucy says that Lily has never been to Guangzhou. → Lucy said that Lily had never been to Guangzhou.

四 . 做题时考虑的问题

人称代词要作的变动。例如：

Do you have any cheaper ones？ Mother asked the shopkeeper.

Mother asked the shopkeeper if / whether you had any cheaper one.

（妈妈问你们还有更便宜的。）（误）

Mother asked the shopkeeper if / whether they had any cheaper ones.

（妈妈问还有更便宜的。）（正）

当你遇到宾语从句的时候，如都能从几个考虑，，难题就可以迎刃而解了。
