答案：
文章大意：本文介绍了跑马拉松前要做的准备工作和训练内容，包括鞋子的选择以及如何循序渐进地增加训练时间和运动量。
1．c 文章第一句概括介绍了跑马拉松前要做的准备工作和训练内容，空格后面一句是说买跑鞋的问题，所以c项before you begin your training放在此处可起到承上启下的作用。
2．e 上一句说如果跑鞋看起来挺合适，多穿几天再次核实鞋是否合脚。e项if they still feel good，you can begin running in them(如果这双鞋子穿起来仍然感觉不错，那么你就可以穿着跑步了。)是上一句的延伸，故选e项。
3．a 根据本段第一句during the first week...和第三句but during the next week...给出的提示，可知本空说的是时间，a项after six days符合语境。句意为：在第一周，不要考虑距离，每天比前一天多跑五分钟。六天之后休息一天是明智的。
4．d 前面提到第一周不要考虑跑的距离，但是从第二周开始，每次跑步至少要跑1.5英里，可知本段是说要循序渐进加大训练量，这与d项(每天都要增加0.5英里)表达的信息一致，故选d项。
