the cake is being made by the girl 为什么和my homework was finished by me 不一样为什么不能用 the cke is made by the girl为什么不能用the cake is made by the girl
the cake is being made by the girl用is being表示这块蛋糕正在被这个女孩制作,而the cake made by the girl是指这块的蛋糕是被这个女孩做的 .
my homework was finished by me是被动语态,换为主动语态就是I finished my homework.含有过去式的句子变被动语态就是was\were + 动词的过去分词.

the cake is being made by the girl 现在进行时态，强调的是动作此时此刻正在进行。如果用the cake is made by the girl,是一般现在时态，表示经常性的动作。你想想合理吗
这里是强调动作在进行。
希望对你有帮助。
