单项选择题
"In the past we were a lonely car maker, but we had good business," says Bernd Engelstadter, technical executive director at Shanghai Volkswagen, adding to he arrived in China seven years ago "competition was not a problem".
A．that
B．when
C．that when
D．when that
答案
参考答案：C
解析：[分析]结构应用 adding…这部分在句中是现在分词短语做伴随状语，而伴随状语从句中又带一个复合句表示：当他七年前到中国时“竞争不是个问题”，因此adding后应是一个that引导的从句，在这一从句中的时间状语应用when来连接；因此C为答案。
