Question

I met with old friend Tim,who I saw two years ago last time.

Answer 1

答案：B

beginning of term :开学.

at the beginning of term :开学的时候.

这里的固定搭配是 ” at + 时间点“ ,而不止是”at the beginning of",只从后者看问题很容易犯错误,因为如果of后面的句子成分不正确,前面选择了这个短语最后还是会犯错.

本句中额外考察的短语是“beginning of term” 开学,省略了term前的定语the,具有一定的混淆性.
