前面三个空in 和at都可以填的
第四个空只能填at at the table是固定短语,坐在桌子旁就餐的意思.
in 和 at 后面跟地点的时候通常是 in 跟较大的地方 at 跟较小的地方.不过这里的较大和较小是相对而言的.
如:通常说:in China,in Shanghai
at the school
但是 in the school,in the classroom也是完全正确的.

在表示时间的时候
AT是钟表时间 比如 在3点
而IN则是比较大的时间 如 月,年。。。
在表示地点的时候
AT是很小的地点
IN则是大地点
还有在具体的短语中
如At the weekend .....
