Question

All the thing I had packed so carefully were soon in a dreadful mess.为什么thing不加s?

Answer 1

All the thing I had packed so carefully were soon in a dreadful mess.
所有细心包装好的东西一会儿工夫就乱成一团.
语言点:句子结构分析:
本句中的all the things为先行词,其后的定语从句必须由that引导,即（that）I had packed so carefully;不用which,that可以省去.
In a dreadful mess的意思是“乱成一团”,是固定搭配.
我只能说这里thing应该要加s,没加S的话只能把它看成抽象名词东西了.
