推荐信要求的是“departmental-online” 实在不知道这是个什么东西，我申的是CIVIL ENGINEERING. 这个学校貌似应该是只有一个网申系统，但是却搞出了三个选项：Please check the Departmental Information to determine the details for letters of recommendation as they apply to your major and degree goal. The department information will state either "Graduate Division online", "Department online", or "Paper". If your department accepts "Department online" or "Paper" only, please contact your program for more details.
The application states that recommenders use a "Departmental-Online" system. This means that applicants need to enter their recommenders' information onto the application, and then submit the entire, completed application. Once the application is received by CEE, an e-mail message is generated to you. This can take up to 5 business days.
这是系里面的说明，到底什么意思，系里的申请链接又直接连回了所谓的 "Graduate Division online"
