解析試題分析：句意：李娜是如此著名以致于所有在中國的網(wǎng)球迷都認識她。 
so．．．that，too．．．to和enough to是初中英語教材中的重要結構。在一定條件下它們可以相互轉換。
一、so．．．that與too．．．to的轉換
當that引導的從句為否定式時，從句主語與主語的主語相同時，so．．．that可轉換為too．．．to結構；若從句主語與主句的主語不相同時，so．．．that可轉換為too．．．for sb．to結構。例如： He is so young that he can't go to school．→ He is too young to go to school．
二、so．．．that與enough to的轉換
1．當that引導的從句為肯定式時，若從句主語與主句主語相同時，so．．．that可轉換為 enough to結構；若從句主語與主句主語不相同時，so．．．that可轉換為enough for sb．to結構。例如：
Tom is so old that he can go to school．→Tom is old enough to go to school．
2．當that引導的從句為否定式時，若從句主語與主句主語相同時，so．．．that可轉換為enough to的否定結構；若從句主語與主句主語不相同時，so．．．that可轉換為 enough for sb．to的否定結構。注意：轉換后的形容詞（副詞）要用其相應的反義詞。例如：
The man is so old that he can't go to work．→The man isn't young enough to go to work．
三、enough to的句式為否定式時，enough to可以轉換為too．．．to結構。但轉換后的too．．．to結構中的形容詞（副詞）要用其相應的反義詞。例如：
He is not old enough to do the job．→He is too young to do the job．
Tom didn't walk slowly enough for us to keep up with him．→Tom walked too fast for us to keep up with him．
故選D
考點：考查固定短語用法。
