______ once every two years, whether it is a car, a bus or a lorry, is the rule that all drivers must obey in our country.

A．Having been examined	B．Examined
C．Examining	D．Being examined

答案

D

解析

试题分析：考查动名词做主语，whether it is a car, a bus or a lorry,是插入语，暂时现不看，可以看出is是谓语，前面的是主语，a car, a bus or a lorry和examine是被动关系，用动名词的被动作主语，句意：不管是汽车，公共汽车还是货车每年检查两次是我们国家司机必须遵守的规定。选D。
点评：此类题目首先要分析句子成分，弄清在句中的作用，再做题，作主语的时候要看成分分析。
