▲高考英語(yǔ)語(yǔ)法必考知識(shí)點(diǎn):目的狀語(yǔ)從句
目的狀語(yǔ)從句:從句部分是用以補(bǔ)充說(shuō)明主句中謂語(yǔ)動(dòng)詞發(fā)生的目的的狀語(yǔ)從句。
表示目的狀語(yǔ)的從句可以由that, so that, in order that, lest, for fear that, in case等詞引導(dǎo);
目的狀語(yǔ)從句的謂語(yǔ)常含有may, might, can, could, should, will, would等情態(tài)動(dòng)詞。
例如:
You must speak louder so that /in order that you can be heard by all.
He wrote the name down for fear that(lest) he should forget it.
Better takes more clothes in case the weather is cold.
引導(dǎo)目的狀語(yǔ)從句常用的連詞有:
Say it louder(so)that everyone can hear you.
大聲說(shuō),以便大家都能聽(tīng)到你。
I am telling you that lest you should make a mistake.
我告訴你這一點(diǎn),以免你搞錯(cuò)。
學(xué)習(xí)目的狀語(yǔ)從句應(yīng)注意以下:
(1)目的狀語(yǔ)從句中常含有can,could,may,might,should等情態(tài)動(dòng)詞。
I got up early so that I could catch the first bus.
我起得很早,目的是為了趕上頭班公共汽車(chē)。
(2)在口語(yǔ)中so可以引導(dǎo)目的狀語(yǔ)從句。
We'll sit nearer the front so we can hear better.
我們坐的靠前一點(diǎn),因此,我們聽(tīng)得清楚一點(diǎn)。
【注意】in order that與in order to的區(qū)別:
in order that+從句
in order to+動(dòng)詞原形 ( in order to后面加的那個(gè)不叫目的狀語(yǔ)從句,叫目的狀語(yǔ))
in order to 為了,后接動(dòng)詞原形,做目的狀語(yǔ)。
i get up early in order to catch the early bus.
in order that 為了,后接從句,做目的狀語(yǔ)。
i get up early in order that i can catch the early bus.
目的狀語(yǔ)從句的一個(gè)特點(diǎn):
由于目的都是未來(lái)的行為,所以從句中一般用表示未來(lái)可能性時(shí)態(tài),
當(dāng)然還可以用will,would,can,等
▲高考英語(yǔ)語(yǔ)法必考知識(shí)點(diǎn):目的狀語(yǔ)從句的用法
目的狀語(yǔ)從句可以由表示“為了, 以便”的so that(有時(shí)省略so), in order that和表示“以免, 以防”的lest, for fear that, in case引導(dǎo)(lest, for fear that后的目的狀語(yǔ)從句一般要用“可以省略的should+動(dòng)詞原形”的虛擬語(yǔ)氣形式; in case后的目的狀語(yǔ)從句多用虛擬語(yǔ)氣, 但也可用陳述語(yǔ)氣)。例如: They set out early that they might arrive in time. 他們?cè)琰c(diǎn)動(dòng)身, 以便及時(shí)到達(dá)。// She takes notes carefully in class so that she may use them when she reviews her lessons after class. 她在課堂上認(rèn)真記筆記, 以便她能在課后很好地復(fù)習(xí)功課。// He shouted at the top of his voice in order that he might be heard. 他盡力大聲叫喊, 以便別人能聽(tīng)見(jiàn)。// I will not make a noise lest I (should) disturb you. 我不出聲, 以免打攪你。// He is working hard for fear that he (should) fail. 他認(rèn)真學(xué)習(xí), 以免考不及格。// Take your umbrella in case it rains. 帶上雨傘, 以防下雨。
如果表示“為了, 以便”的目的狀語(yǔ)從句的主語(yǔ)與主句的主語(yǔ)相同, 可用in order to或 so as to取代該目的狀語(yǔ)從句, 注意體會(huì)以下例句: He hurried through his work in order to catch the train. 他匆匆干完手中的活, 為的是能趕上火車(chē)。// I sent the plans in order for you to study them fully before the meeting. 我寄上這些計(jì)劃以使你會(huì)前充分研究一下。 // The desks are kept some distance apart, so as to prevent cheating. 這些書(shū)桌都隔著一段距離擺放, 以防作弊。 // I came so early as to catch the first train. 我起得早, 以便能趕上頭班火車(chē)。
