Itis recommended that the system of buying train tickets in real names ------ out during the Spring Festival选A后半部分是一句从句，所所以缺谓语，不能用非谓语，C不对由时间状语during the Spring Festival知道是发生在将来的，所以用将来时，又是被动，所以选A有不会的可以再问我

B这是高一的难度。当谓语动词是require, recommend, order, command, request, suggest, advise等动词时，主语从句要用should do这种虚拟语气，should可以省略。
