解答 When I turned 18last July，I decided to learn driving．My brother volunteers to teach me，but he lacked of patience．Whenever I made the mistake he would get angry with me．I felt such discouraged that I wanted to give up．Before knowing what I was thinking，my friend Torn encouraged me∧learn in a driving school．I followed his advice and under the guidance of my coach，I regained confidence．With time goes on，I found driving not only interesting but also very easily．At last，I passed the driving test at the first attempt．At that moment，I got really exciting and could hardly keep back my tear．
详解：
1．volunteers改为volunteered；考查动词的时态，本文讲述过去发生的事情，要用一般过去时．
2．去掉of；考查动词，此处lack用作及物动词，后面可直接跟宾语，故去掉of．
3．the改为a；考查冠词，此处mistake是可数名词，在文中第一次出现，要用不定冠词a泛指"一个"．
4．such改为so；考查近义词辨析，在so/such…that结构中，such后面跟名词，so后面跟形容词或副词，此处discouraged是形容词，故用so．
5．Before改为After；考查句意，分析句意为"知道了我的想法以后，朋友Torn鼓励我…"，故用After．
6．me后面加to；考查动词不定式，encourage sb to do sth是固定搭配，意为"鼓励某人做某事"．
7．goes改为going；考查with复合结构，with是介词，后面跟名词或名词性短语，又time与动词go存在逻辑上的主谓关系，故用going．
8．easily改为easy；考查形容词，此处用形容词easy与前面的interesting构成并列成分，作宾补．
9．exctiing改为excited；考查分词作形容词，现在分词作形容词修饰物，过去分词作形容词修饰人，此处主语为I，故用过去分词形式．
10．tear改为tears；考查名词，tear是可数名词，结合句意应该用复数形式．
点评 短文改错时首先要通读全文，了解文章基本大意，然后细读短文，分析句子结构和句群关系，运用所掌握的词汇，语法，固定搭配等基础知识找出文中错误并加以修改．
