32、He worked and overcame thousands of .Finally，he entered a university in he wrote many story books.Up till now， only forty，he has been very famous around the country.第一处：ready后加to。考查动词不定式。be ready to do sth.为固定用法，意为“准备好做某事；乐于做某事”。第二处：but改为and/so。考查连词。Mike乐于助人，因此他在社区很受欢迎。根据语境可知，此处用and/so连接两个并列分句。第三处：u
33、s改为me。考查代词。第二段谈及的都是Mike与作者本人之间的事，所以us改为me。第四处：about改为with。考查介词。Mike用他自己的经历鼓励作者。with在此意为“以，使用”。第五处：删除to。考查介词。tell sb.sth.为固定用法，意为“告诉某人某事”。第六处：has改为had。考查时态。根据句中的As a little boy可知，此处叙述的是过去的事，故用一般过去时。第七处：hardly改为hard。考查副词。Mike学习努力，克服了很多困难。hard“努力地”，符合语境。hardly意为“几乎不”。第八处：difficulty改为difficulties。考查名词的数。根据句中的thousands of可知，此处用名词的复数形式。第九处：that改为which。考查定语从句。定语从句的先行词为university，关系词作介词in的宾语，所以用“in which”引导定语从句。第十处：aging改为aged。考查形容词。aged为形容词，意为“岁”，符合语境。
