I have been reading a book about Henry Ford．He was an eldest son of a farmer in Michigan．His father hoped he would help him on the farm，and Henry was not interested in farm work at all．He did everything he could∧keep away from it．Therefore，Henry was not a lazy boy．He was addicted in mechanical work．Later，Henry took a job as a mechanic，showing greatly interest in steam engines．In 1908，he had built the famous"Model T"．This car was∧popular that it was unchanging for twenty years．Five years after that，he started the Ford Motor Company，what made the US a nation on wheels and helped the US become what it is now．
详
1．an改为the 考查冠词．eldest是形容词最高级，其前加定冠词the．
2．and改为but 考查连词．前后两个单句表示转折关系，而非并列关系，用连词but．
3．加to 考查动词不定式．he could do是定语从句修饰先行词everything，因主句中有did，从句中的do要省略，此处动词不定式表示目的，作目的状语．
4．Therefore改为However 考查副词．however表示转折，尤其用于谈及一个既成事实时，表示转折，其意为"可是""仍然"等．可放在句首、句中或句末，通常用逗号与句子其他成分隔开．
5．in改为to 考查介词．be addicted to意为"沉迷于"，是固定搭配．
6．greatly改为great 考查形容词．interest是名词，要用形容词修饰．
7．the改为a 考查冠词．Model是可数名词，单数形式前加不定冠词a表示泛指．
8．加so 考查固定搭配．so…that…意为"如此/这么…以致于…"，句型中的so是副词，常常用来修饰形容词或副词，常用句型为：主语+谓语+so+adj．/adv．+that从句．
9．unchanging改为unchanged 考查动词语态．it与unchange之间是动宾关系，要用一般过去时的被动语态．
10．what改为which 考查定语从句．分析句子结构可知这是一个定语从句，先行词是前面整个句子，在从句中作主语，用关系代词which．
