初中英语语法大全汇总初中英语语法练习题二轮复习从句
从句是相对于主句而言的，即它是从属于某一个主句，而不能单独作一个句子。在英语中，主要有三大从句，即名词性从句（包括主语从句，宾语从句，表语从句，同位语从句）、形容词性从句（即定语从句）、副词性从句（即状语从句，包括时间、条件、结果、目的、原因、让步、地点、方式等）。

宾语从句的复合句转化为简单句（六种方法），使其与原句意思相同（或相近）的初中英语语法练习题试题。 

方法一：当主句谓语动词是hope， decide， wish， choose， agree， promise（和主观决定有关）等，且宾语从句的主语与主句主语一致时，宾语从句可简化为不定式结构。例如：
Li Ming hopes he will be back very soon. →Li Ming hopes to be back very so on. 
We decided that we would help him. →We decided to help him. 

方法二：当主句谓语动 词是know， learn， remember， forget， tell（和记忆认知有关）等动词，且主句主语与从句主语一致时，宾语从句可简化为“ 疑问词+不定式”结构。例如：
She has forgotten how she can open the window. →She has forgotten how to open the window. 

注：当主句谓语动词是tell， ask， show， teach等动词，且后带双宾语，从句主语和间接宾语一致时，宾语从句可简化为“疑问词+不定式”结构。例如： 
Could you tell me how I can get to the station？ →Could you tell me how to get to the station？ 

方法三：当主句的谓语动词是order（命令），require（需要）等时，如果主句和从句的主语不一致，宾语从句可简化为“名词（代词）+不定式”结构。例如：
The headmaster ordered that w e should start at once. → The headmaster ordered us to start at once. 

方法四：某些动词后的宾语从句，可以用介词加动名词（短语）等其他英语记单词方法形式简化。例如：
He insisted that he should go with us. →He insisted on g oing with us. 
The poor boy doesn’t know when and where he was born. →The poor boy doesn’t know the time and the place of his birth. 

方法五：某些动词后面的宾语从句可转化为“宾语+V-ing形式（作宾语补足语）”结构。例如：
Liu Ping found that there was a wallet lying on the ground. → Liu Ping found a wallet lying on the ground. 

方法六：动词seem后的宾语从句，也可以用不定式（短语）来简化，但句型需要进行适当的变化。例如 ：
It seemed that the boys were going to win. →The boys seemed to win.

除上述方法外，还有一些特殊句式的转化。例如：
I found that it was difficult to learn English well. →I found it difficult to learn English well.

Soon we found that the ground was covered with thick snow. →Soon we found the ground covered with thick snow.

They found that the box was very heavy. →They fo und the box very heavy
