Question

Peter was so excited ______ he received an invitation from his friend to attend the wedding.

A．where

B．that

C．why

D．when

Answer 1

D

试题分析：考查状语从句。状语从句：when he received an invitation from his friend to attend the wedding.修饰整个一句话Peter was so excited句意：当他收到来自朋友的婚礼请柬的时候，他非常高兴。根据句意说明D正确。
点评：：状语从句的考查要从句意出发，同时要注意所使用连接词的用法，疑问副词在句中做状语，疑问代词在句中做主语，宾语，表语或者定语。
