1、引導(dǎo)目的狀語從句時(shí),表示“以便；為了”,從句中常使用can/could/may/might/will/would/should等情態(tài)動(dòng)詞或助動(dòng)詞；引導(dǎo)結(jié)果狀語從句時(shí),從句中一般不用can和may等詞,在so that前可以用逗號(hào),意思是“因此;所以”.如：

　　The little boy saved every coin so that he could buy his mother a present on Mother's day.

　　小男孩存了每一個(gè)硬幣，以便在母親節(jié)給母親買禮物。

　　2、so...that..，so＋形容詞或副詞＋that...引導(dǎo)結(jié)果狀語從句.意思是“如此……以致于……”.如：

　　When the football fans saw Beckham,they got so excited that they cried out.

　　當(dāng)球迷看到貝克漢姆時(shí)，他們激動(dòng)得哭了起來。
