选择题
______ 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
答案:D
题目分析: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。
