【小知識(shí)】簡(jiǎn)化賓語(yǔ)從句常用方法
同學(xué)們常會(huì)遇到把含有賓語(yǔ)從句的復(fù)合句轉(zhuǎn)化為簡(jiǎn)單句，使其與原句意思相同（或相近）的試題。下面就介紹幾種常用的簡(jiǎn)化賓語(yǔ)從句的方法：

方法一：當(dāng)主句謂語(yǔ)動(dòng)詞是hope， decide， wish， choose， agree， promise等，且賓語(yǔ)從句的主語(yǔ)與主句主語(yǔ)一致時(shí)，賓語(yǔ)從句可簡(jiǎn)化為不定式結(jié)構(gòu)。例如：
Li Ming hopes he will be back very soon. →Li Ming hopes to be back very soon.
We decided that we would help him. →We decided to help him.

方法二：當(dāng)主句謂語(yǔ)動(dòng)詞是know， learn， remember， forget， tell等動(dòng)詞，且主句主語(yǔ)與從句主語(yǔ)一致時(shí)，賓語(yǔ)從句可簡(jiǎn)化為“疑問(wèn)詞+不定式”結(jié)構(gòu)。例如：
She has forgotten how she can open the window. →She has forgotten how to open the window.
注：當(dāng)主句謂語(yǔ)動(dòng)詞是tell， ask， show， teach等動(dòng)詞，且后帶雙賓語(yǔ)，從句主語(yǔ)和間接賓語(yǔ)一致時(shí)，賓語(yǔ)從句可簡(jiǎn)化為“疑問(wèn)詞+不定式”結(jié)構(gòu)。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：當(dāng)主句的謂語(yǔ)動(dòng)詞是order（命令），require（需要）等時(shí)，如果主句和從句的主語(yǔ)不一致，賓語(yǔ)從句可簡(jiǎn)化為“名詞（代詞）+不定式”結(jié)構(gòu)。例如：
The headmaster ordered that we should start at once. → The headmaster ordered us to start at once.
