问题描述：
Many people gave money and food to c____ after the earthquake in Yingjiang Yunnan.
答案里面是charities,但是课本里有give it to charity为什么这里是单数呢?是固定搭配吗?
还有一个，keep sb.out 是不是“ 不让某人进去” 的意思？
答
不是固定搭配的是根据句意、语境选择的 Many people gave money and food to charities after the earthquake in Yingjiang Yunnan.云南盈江地震之后,很多人捐了很多钱和实物给慈善机构.（因为不可能只捐给一个慈善...还有一个，keep sb. out 是不是“ 不让某人进去” 的意思？keep sb out of （sth) 不让入内 这个用法肯定要有（of sth)不让进入（sth）
