如何判斷so that引導(dǎo)的目的狀語從句與結(jié)果狀語從句,？

so that后既可跟目的狀語從句,也可跟結(jié)果狀語從句。如何判斷?下面的方去可幫助你解決問題,。

一.當(dāng)表達(dá)的含義是“ 為了... 以....時(shí),，為目的狀語從句;當(dāng) 表達(dá)的是以至.....因此”含義時(shí),為結(jié)果狀語從句。例如:

If you do know,，answer in a loud- enough voice so that all the class mayhear.(目的狀語從句)如果你的確知道,應(yīng)大聲回答,，以便讓全班學(xué)生都可以聽見。

It rained hard the day before yesterday ,so that she had to stay at home. (結(jié)果狀語從句)前天雨下得很大,，因此她只好呆在家里,。

二、當(dāng)從句的謂語動(dòng)詞有情態(tài)動(dòng)詞can,could,may,might等時(shí),是目的狀語從句;當(dāng)從句里沒有情態(tài)動(dòng)詞,，且謂語動(dòng)詞是一-般 現(xiàn)在時(shí)(過去時(shí)),、現(xiàn)在完成時(shí)等時(shí)態(tài)時(shí),是結(jié)果狀語從句。例如:

We stopped at Salt Lake City so that we could( might ) visit the monument to seagulls.(目的狀語從句)我們在鹽湖城逗留,，以便可以參觀為海鷗修的紀(jì)念碑,。

They have walked a long way , so that they are all tired. ( 結(jié)果狀語從句)他們走了很長的路,所以都很累。

三,、當(dāng)從句之前的so that可用in order that代替時(shí),，是目的狀語從句;反之,是結(jié)果狀語從句。例如:

We now study hard so that we may work well in the future. ( = We now study hard in order that we may work well in the future. )(目的狀語從句)我們現(xiàn)在努力學(xué)習(xí)是為了將來更好地工作,。

四,、當(dāng)so that之前有逗號時(shí),是結(jié)果狀語從句;反之,是目的狀語從句。例如:

The story is very interesting,so that I like it very much. (結(jié)果狀語從后,、這部小說很有趣,，因而我非常喜歡。
