Unit 10 By the time I got outside, the bus had already left.

(1)so...that在這里引導結果狀語從句，表示“如此……以至于……”，so強調形容詞或副詞，that后面接從句，常用于下面的結構中：
 
例如：
the computer is so useful that each of us wants to buy one.
計算機太有用了，我們每個人都想買一臺。
he ran so fast that we couldn’t catch up with him. 他跑得太快，我們追不上他。
he had so many falls that he could ride a bike at last.
他摔了很多跤，終于學會了騎車。
there’s so much noise in the meeting room that i can’t hear the speaker clearly.
會議室里的噪音太大，我聽不清演講者的發言。
知識拓展：
so...that句型轉換的四種方法：
◎當從句的主語與主句中的主語一致，且that從句是否定式時，常用too...to...轉換。
the little girl was so tired that she couldn’t walk farther.
=the little girl was too tired to walk farther.
這個小女孩太累了，她不能再走更遠的路了。
◎當從句的主語與主句中的主語不一致，且that從句是否定式時，常用too...for sb to do sth轉換。
the work is so difficult that we can’t finish it in time.
=the work is too difficult for us to finish it in time.
這份工作太難了，我們不能按時完成。
◎當從句的主語與主句中的主語一致，且that從句是肯定式時，常用...enough to do sth轉換。
he is so strong that he can lift the heavy box.
=he is strong enough to lift the heavy box.他強壯得足以舉起那個重箱子。
◎當從句的主語與主句中的主語不一致，且that從句是肯定式時，常用...enough for sb to do sth轉換。
he spoke so clearly that i could hear him.
=he spoke clearly enough for me to hear him.他說得很清楚，我能聽明白。
特別提示：
so that連在一起使用，意為“為了，以便”，表示目的，此時主句和從句的主語不一定一致；另外，還可以引導結果狀語從句，前面一般用逗號。
speak louder so that we can hear you. 你說大聲點兒，以便我們能聽得見。
she was ill, so that she was unable to go with you. 她病了，不能和你一起去了。
