问题描述:

I didn't go to this party last night ,because() I changed my mind
a on second thought
b on the second thought
选哪个,为什么,

on second thought 固定搭配。
thought 不止是think 的过去式和过去分词,它还可以作为名词,意思是考虑,思量。second, 表面意思是第二,second thought 就是再想一遍,也就是汉语中三思的意思啦。前面不需要加the, 因为是固定搭配的。

C.on second thoughts 理由:on second thoughts 意为“进一步考虑后,经再三考虑之后,经重新考虑”,对应后面的话“我改变了主意”。 C on second

a on second thought
这是个固定短语,表示“经过深思熟虑以后”

b on the second thought
second 是序数词,前面加定冠词 the 。
