A.Submit your design work.

B.Pay 300 pounds in advance.

参考答案：D

参考解析：

细节理解题。根据How to apply下的“submit a 300-word statement of interest outlining your relevant experience or practice and why you would like to join the Architecture Summer School.”可知，填完申请表后再提交一份300字的兴趣声明，概述你的相关经验或实践，以及为什么你想加入建筑暑期学校。D项“描述你加入这个学校的原因”符合题意。故选D。
