tyger老师一直引导我们，要学会存疑。
上次25讲在整理课堂笔记的
在lesson 31 学习中，遇到几个问题
自己查了查，不知道理解的对不
1.for与of对比
相同：定语后置
不同：for“给”的意思
of“的”的意思
of: Frank used to the head of a very large business company.
for: Frank used to make spare parts for areoplances.
2.people与person
不同：people“人”
person“一个人”
所以In a few years the small workshop had become a larger factory which employed seven hundred and twenty-eight people.
3.used to、always与be used to
