Get cold feet 表示临到最后一刻失去勇气、打起退堂鼓。一个人已决定结婚、搬家或跳伞，却在行动前害怕起来，开始怀疑决定，甚至退出，就可以这样说。这个习语偏口语；如果确实放弃了计划，IELTS 作文中可以用更中性的 decided not to go ahead。

get/have cold feet (about + noun/-ing)
- Tom got cold feet the night before his wedding, but he turned up at the church in the end.
- I was going to quit my job and travel for a year, but I got cold feet.
- Two investors got cold feet about the project when the costs started to rise.
修改原因
修改前He got cold legs and didn't sign the contract.
修改后He got cold feet and didn't sign the contract.
Legs 与 feet 都是身体部位词，容易混淆，但这个习语固定使用 feet，而且必须是复数。修改后的句子只把 legs 换成了 feet。
Have second thoughts 语气较轻，表示重新考虑、产生疑虑，但不一定改变决定：I had second thoughts about the flat, but I signed the contract anyway。Get cold feet 更强调害怕而退缩，常导致退出。如果脚真的冷了，直接说 My feet are cold。
动手练习
Maria had booked a parachute jump for her birthday, but when she saw the tiny plane, she ___ and went home.
查看答案
got cold feet — Maria 已经预订跳伞，却看到小飞机后害怕，临时退出并回家，因此选 got cold feet。Itchy feet 表示想动身去旅行的冲动，而她此时是放弃活动回家。
回想你或认识的人临到行动前突然胆怯的一次经历。说清楚本来准备做什么，以及最后的结果。
My brother got cold feet before his first job interview in English, so he moved it to the following week.
