同学你好~
Because of the busmen's strike, which begins on Tuesday and may last a week
这部分是介词短语because of引导的原因状语
其中which begins on Tuesday and may last a week是非限定性定语从句，修饰strike

car owners have offered to give rides to people going to work 这部分是主句
其中have offered作谓语，是现在完成时
offer sth to sb，这里是双宾语结构
going to work是现在分词短语作定语，修饰people

祝同学学习进步~
