详解：
1．去掉of 考查词语用法．think是动词，用副词修饰，a lot意为"许多，大量"是副词；a lot of后接名词．
2．加to 考查动词不定式．此处动词不定式表示目的，作目的状语．
3．habit改为habits 考查名词复数．habit是可数名词，其前有some修饰时用复数形式．
4．see改为seeing 考查动名词．seeing movies与playing computer games并列，作为such as的列举对象．
5．other改为another 考查词词语用法．for one reason…for another reason…意为"一个原因是…； 另一个原因是…"，是固定搭配．
6．don't改为doesn't 考查主谓一致．buying a laptop computer是动名词作主语，谓语动词用单数形式．
7．去掉a 考查冠词．progress是不可数名词，其前不加不定冠词a．
8．but改为and 考查连词．put和work并列，作need的并列宾语．
9．had改为have 考查动词时态．全文讲述的是一般事实，用一般现在时态．
10．to改为with 考查词语用法．agree with意为"与某人〔观点〕一致，同意〔赞同〕某人的意见"，是固定搭配．
点评 高考短文改错题的形式有说明文，短文故事，书信等，具有很强的实用性．短文的内容和语言都符合高中学生的实际，从表面上看类似一篇学生习作．首先，通读全文，了解短文大意，把握全篇的时态、人称及行文逻辑，在通读全文时把一些容易的错误先改好，再进行逐句改错．其次，要进行逐个句子的改错．这是要对文中的词法、句法和语篇着重分析和特别注意．最后把改好的短文再阅读一遍，检查答案是否正确，感觉是否还有不妥之处，最终形成定稿．
