[專題輔導(dǎo)]怎樣簡(jiǎn)化狀語(yǔ)從句？
我們?cè)谟⒄Z(yǔ)寫作中經(jīng)常要用到狀語(yǔ)從句，狀語(yǔ)從句是指句子用作狀語(yǔ)時(shí)，起副詞作用的句子。狀語(yǔ)從句中的從句可以修飾謂語(yǔ)、非謂語(yǔ)動(dòng)詞、定語(yǔ)、狀語(yǔ)或整個(gè)句子。對(duì)于一個(gè)初學(xué)寫作的人來說，學(xué)會(huì)簡(jiǎn)化狀語(yǔ)從句，會(huì)使整篇文章顯得條理很清楚，今天小編給大家?guī)碓鯓雍?jiǎn)化狀語(yǔ)從句。
1.以after和before引導(dǎo)的狀語(yǔ)從句的主語(yǔ)若與主句主語(yǔ)一致時(shí)，可用after和before與從句謂語(yǔ)動(dòng)詞的動(dòng)名詞(短語(yǔ))形式構(gòu)成介詞短語(yǔ)作狀語(yǔ)。
例如：
after she sang，she left the rich man's house.(簡(jiǎn)化前)
after singing，she left the richman's house.(簡(jiǎn)化后)
2.以as soon as引導(dǎo)的狀語(yǔ)從句的主語(yǔ)若與主句主語(yǔ)一致時(shí)，可用on十v-ing形式簡(jiǎn)化狀語(yǔ)從句，此時(shí)的動(dòng)詞為非延續(xù)性動(dòng)詞。例如：
dr.bethune began to operateon the wounded soldiers as soon as he arived at the village.(簡(jiǎn)化前)
dr.bethune began to operateon the wounded soldiers on arriving at the village.(簡(jiǎn)化后)
3.時(shí)間狀語(yǔ)從句和條件狀語(yǔ)從句的主語(yǔ)和主句主語(yǔ)一致時(shí)，有時(shí)可簡(jiǎn)化為不定式作狀語(yǔ)。例如：
she stopped when she saw her husband.(簡(jiǎn)化前)
she stopped to see her husband.(簡(jiǎn)化后)
if you want to understand the farmers，you must go to the countryside.(簡(jiǎn)化前)

4.結(jié)果狀語(yǔ)從句和目的狀語(yǔ)從句的主語(yǔ)與主句主語(yǔ)一致時(shí)，可以簡(jiǎn)化為不定式作狀語(yǔ);若兩者主語(yǔ)不一致時(shí)，則應(yīng)簡(jiǎn)化為不定式的復(fù)合結(jié)構(gòu)作狀語(yǔ)。例如：
he was so tied that he couldn't go any further.(簡(jiǎn)化前)
he was too tied to go any further.(簡(jiǎn)化后)
i came here so that i could ask some questions.(簡(jiǎn)化前)
i came here(in order) to ask some questions.(簡(jiǎn)化后)
5.以when，while引導(dǎo)的時(shí)間狀語(yǔ)從句和以if引導(dǎo)的條件狀語(yǔ)從句，如果從句主語(yǔ)和主句主語(yǔ)一致時(shí)，可簡(jiǎn)化為現(xiàn)在分詞狀語(yǔ)，表示謂語(yǔ)動(dòng)作發(fā)生在該狀語(yǔ)動(dòng)作的進(jìn)行過程之中。
例如：
when he turned on the radio，he found it broken.(簡(jiǎn)化前)

not knowing chinese，i tried to speak to her in english.(簡(jiǎn)化后)
要注意的是，形容詞短語(yǔ)也可用作表示原因的狀語(yǔ)，用以代替原因狀語(yǔ)從句，放在句首、句末均可，但一般應(yīng)加逗號(hào)。例如：
as he was thirsty and eager to get a little rest，he went into the tea-house.(簡(jiǎn)化前)
thirsty and eager to get a little rest，he went into the tea-house.(簡(jiǎn)化后)
7.在時(shí)間、原因、條件等狀語(yǔ)從句中，若從句和主句主語(yǔ)不一致時(shí)，可簡(jiǎn)化為分詞復(fù)合結(jié)構(gòu)作狀語(yǔ)。有時(shí)也可簡(jiǎn)化為“with/without名詞或代詞十分詞(短語(yǔ))”形式作狀語(yǔ)。例如：
