He was so angry when he couldn't find anything to write me a ticket for that he gave me the finger as he drove away.

    【分析】（1） to write me a ticket for 是动词不定式短语，作 anything 的定语。（2）so...that...引导结果状语从句（这里的 so 是程度副词，后面接形容词或者副词的原级形式）。（3）when he couldn't find anything to write me a ticket for 和 as he drove away 是时间状语从句。

应该是：to write me a ticket for that

不定式作“目的状语”，for that 指“为纠纷或违章的事”。

write sb. sth. 给某人写书面的东西。如：write me a letter （给我写信）

He was so angry when he couldn't find anything to write me a ticket for that he gave me the finger as he drove away.

【翻译】当他找不到任何东西给我开罚单时，他非常生气，开车走的时候还骂人。
