【解析】
1．考查定语从句。本句是含有定语从句的复合句，先行词是one afternoon，关系副词在定语从句中作时间状语，所以此处应用表示时间的when。故将where改为when。
2．考查连词。句意：突然一个足球落在我前边并且差点打到我。“足球落下来”与“打到我”两个动作是顺承关系，不是转折关系。故将but改为and。
3．考查there be句型。句意：这项决定有两个原因。句中的they在前边句中找不到指代关系，且后边句子中的one与the other是对这两个原因的解释，故此处要用there be句型。故将they改为there。
4．考查连词。句意：在高中学化学的时候，我重新考虑了自己的目标并决定变成一名医生。“重新考虑”与“决定变成一名医生”之间是顺承关系，不是选择关系。故将or改为and。
5．考查定语从句。先行词environment在从句中作主语，指物，关系代词用that/which。故把what改为that/which。
6．考查连词。根据he agreed可知，和前面的句子是顺承关系，故把but改成and。
7．考查定语从句。which they raised fish是非限制*定语从句，先行词是a small pond，在从句中作地点状语，所以用关系副词引导。故把which改成where。
8．考查连词。句意：句意：我父母在我小的时候教会我的游戏后来在我生活中是非常有用的。表示“当我还是个孩子的时候”，故把where改成when。
9．考查连词。句意：每个人都沉默，等着看谁会被叫起来大声读他或她的文章。根据语境可知，his and her paragraph应该是选择关系，故把and改成or。
10．考查连词。句意：在进入车之前，我认为我已经明白了教练的指示，但是一旦我上了车，我的大脑一片空白。此处是转折关系，故把so改成but。
11．考查固定句型。句意：在过去的几年里，我不仅生理上成长了，而且在精神上也有成长。本句运用了not only…but also句型，故把and改成but。
12．考查定语从句。that is on the rooftop of their house.是非限制*定语从句，此处不能用that，根据先行词是their garden，故把that改成which。
13．考查定语从句。“the things ”后面句子是定语从句，修饰the things，需用作主语的关系代词引导。故把they改成which或that。
