语法与词汇 23.China is investigating whether its new energy vehicle sector suffers from overcapacity as both traditional carmakers and newcomers have been______in recent years.
【正确答案】 B
【答案解析】本题考查习语。分析句子结构可知,have been______这一动作是由traditional carmakers and newcomers发出的,故用主动语态,首先排除[A]项和[C]项。jump/climb/get on the bandwagon为习语,意为“赶时髦,赶浪头”,是“中国正在调查新能源汽车行业是否存在产能过剩问题”的原因,符合语义,故答案为[B]项。jump on the wagon意为“跳上马车”;overcapacity意为“产能过剩”;bandstand意为“(有篷的室外)乐队演奏台”。
