In December of 2006，I was the single parent raising my daughter whom was six years old at the time．I didn't have much money，and I wanted to buy a Christmas tree．I took my daughter along with me．As we were choosing a Christmas tree within my budget，my daughter wanted a big tall tree than that planned one．I told my daughter we can't afford a taller tree．Someone must have heard of our conversation．When I went to paying for the tree，the clerk said the customer before me had paid for my tree．I∧shocked．I was very thankful to what the stranger had done for us．That day I promised to me that I would pay it forward．
详
1．the改为a；冠词错误．此处泛指任何一个单身家长，故用不定冠词．single词首音素是辅音，故不定冠词用a．
2．whom改为who；连词错误．此处为定语从句，whom在引导定语从句时，先行词一般为定语从句中的逻辑宾语．本句先行词my daughter为下文定语从句的逻辑主语．故用who．
3．and改为but；连词错误．句意为转折关系，and表示并列关系，故改为but但是，表示转折关系．
4．big改为bigger；比较级错误．根据下文连词than可知此处表示比较关系，故此处用形容词比较级作定语．
5．can't改为couldn't；时态错误．句意：我告诉我的女儿我们买不起一棵更高的树．此处情态动词需要与主句谓语told保持时态一致，也用一般过去时态．can的过去式是could．故改为couldn‘t．
6．去掉of；动词搭配错误．根据后两句描述可知此处指的是有人听到了我们的谈话．hear of听说．hear听见．此处强调的是听见，故去掉of．
7．paying改为pay；非谓语动词错误．此处to为不定式符号，后面动词用原形．
8．加was；语态错误．根据前一句描述可知我被震惊了．本句主语是动作对象，故用被动语态．句中动作发生在过去，故用一般过去时态．I是第一人称，故be动词用am的过去式was．
9．to改为for短语搭配错误．句意：我非常感激这个陌生人对我们做的事情．be thankful for因为某事而感激．
10．me改为myself；代词错误．句意：那天我就对自己承诺说，我一定要把这份爱传递出去．此处指的是主语本人，故用反身代词myself我自己．
