He is () his thirties
A at B in C for D with
答案是B
As a matter of fact,his students learn a lot () him
A from B by C for D with
答案是A
A at B in C for D with
答案是B
As a matter of fact,his students learn a lot () him
A from B by C for D with
答案是A
He is (in) his thirties
in是指在一段时间中，他30多岁，是在30到40间，所以只能用in。如果用at,是指某个确切的点，显然不合；另外，用for和with都不合。
As a matter of fact,his students learn a lot (from) him
从他那里学到,自然是用from.如果是由他教的，那就要用by；同他一起学的，用with；为他而学，用for.
B
他现在三十多岁.
A
learn from sb
向某人学习.
in one's thirties
是固定结构了，表示某人多少岁，同样也可以说
我今年20几了：I am in my twenties.B
learn from sb
向某人学习.
固定用法!
我个人的选择是B
