英語相似詞辨析(141):so that,so…that

字號:

so that,so…that
    連詞so that和so…that…的涵義和用法并不相同。
    So that的意思是“為了”、“俾使”、“以致”,它引導(dǎo)目的狀語從句和結(jié)果狀語從句。例:
    They opened a technical training course so that the managers and clerks could attend it during their spare time.
    他們開了一個技術(shù)訓(xùn)練班,使經(jīng)理和職員們在業(yè)余的時間可以去上課。
    Please switch the light on so that we can see what it is.
    請開燈,讓我們看一下它是什么東西。
    During the earthquake their house fell with a crash,so that they had to find a new abode.
    地震時,他們的房子嘩啦一聲倒塌了,所以他們必須要找一個新的住處。
    So… that…的意思是“如此地…以致于…”,它引導(dǎo)結(jié)果狀語從句。在口語中,so…that…的that常被省去。例:
    She felt so sad that tears came to her eyes.
    她非常悲傷,淚水盈眶??荚嚧?BR>    John was so drunk(that)he could not stand still.
    約翰醉得站也站不住了。
    He spoke so rapidly(that)we could hardly follow him.
    他說得很快,我們很難聽清楚他在說什么??荚嚧?BR>    應(yīng)當在此指出,有許多英語語法書都提到,so that 在引導(dǎo)結(jié)果狀語從句時,是用陳述語氣,在引導(dǎo)目的狀語從句時,要用虛擬語氣。例如:
    She locked her child in the house when she went out so that it might not be able to go outside and get hurt;but a fire broke out and the door was locked so that the child burnt alive.
    第一個so that引導(dǎo)的是目的狀語從句,第二個so that引導(dǎo)的是結(jié)果狀語從句。事實上,在現(xiàn)代英語中,有不少人在so that引導(dǎo)的目的狀語從句中,是用陳述語氣代替虛擬語氣的(如本節(jié)中的第二個例句中。“wecan see”代替“we could see”)。
