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(rèn)識(shí)她。 
so．．．that，too．．．to和enough to是初中英語教材中的重要結(jié)構(gòu)。在一定條件下它們可以相互轉(zhuǎn)換。
一、so．．．that與too．．．to的轉(zhuǎn)換
當(dāng)that引導(dǎo)的從句為否定式時(shí)，從句主語與主語的主語相同時(shí)，so．．．that可轉(zhuǎn)換為too．．．to結(jié)構(gòu)；若從句主語與主句的主語不相同時(shí)，so．．．that可轉(zhuǎn)換為too．．．for sb．to結(jié)構(gòu)。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(zhuǎn)換
1．當(dāng)that引導(dǎo)的從句為肯定式時(shí)，若從句主語與主句主語相同時(shí)，so．．．that可轉(zhuǎn)換為 enough to結(jié)構(gòu)；若從句主語與主句主語不相同時(shí)，so．．．that可轉(zhuǎn)換為enough for sb．to結(jié)構(gòu)。例如：
Tom is so old that he can go to school．→Tom is old enough to go to school．
2．當(dāng)that引導(dǎo)的從句為否定式時(shí)，若從句主語與主句主語相同時(shí)，so．．．that可轉(zhuǎn)換為enough to的否定結(jié)構(gòu)；若從句主語與主句主語不相同時(shí)，so．．．that可轉(zhuǎn)換為 enough for sb．to的否定結(jié)構(gòu)。注意：轉(zhuǎn)換后的形容詞（副詞）要用其相應(yīng)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(shí)，enough to可以轉(zhuǎn)換為too．．．to結(jié)構(gòu)。但轉(zhuǎn)換后的too．．．to結(jié)構(gòu)中的形容詞（副詞）要用其相應(yīng)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(diǎn)：考查固定短語用法。
