she made the birthday cake herself to give it to her boy friend______her love for him
问题描述：
she made the birthday cake herself to give it to her boy friend______her love for him
a in order to show
b for showing
选a 为什么b错
答
in order to do sth 是固定搭配,表示为了做某事
for doing是错误表达,for 是一个介词,而那个句子需要一个谓语动词,用for 与句子中不能表达一个完整的句子.
