1．将by改为for    考查介词的用法     本句的意思是：从前，有位国王让一位画家为他画画；by"通过，被"；故用for"为，为了"
2．去掉to     考查动词的用法    want是及物动词，其后可直接跟名词作宾语，故去掉to
3．在picture前加the   考查冠词的用法    picture在此处是第二次出现，指为国王画的那幅画；故加the
4．将finish的改为finished    考查形容词的用法   此处用作定语修饰名词picture；表示被动，已完成的动作；意为：那副已完成的画；故用由过去分词转化来的形容词
5．将or改为and      考查连词的用法   根据句意（没有阴影，画面中的一切看起来既平整又不真实）可知，此处表示并列而不是选择关系，故用and
6．将was改为is     考查时态    此处讲述的是该故事给人们留下的启示，指的是它的现实意义，故用一般现在时
7．将 completely改为complete    考查形容词的用法      此处用来修饰名词 picture，故用形容词；意为：一副完整的图画
8．将needs改为need     考查主谓一致    由于本句的主语是People（集体名词：人们），故谓语动词使用原形
9．将lesson改为lessons       考查名词的单复数      根据句意"我们经常在悲伤的时候学到一些经验教训"可知，此处指的不只是一个经验教训；故用名词的复数形式lessons
10．将that改为what       考查连接代词的用法     此处用在动词短语 think about之后，用来引导宾语从句，并且在该从句中作宾语，意为：所学习到的东西；因为that在宾语从句中，没有任何意义，也不作句子成分，只起连接作用；故用what
