应该选哪个？？是不没正确答案啊？答案怎么选D？？

Answer 1

The service is available there three mornings a week at telephone.
从这句我们可以看出电话服务是每周三个早晨有。

答案D every other morning except Sunday是正确的.
一周除了周日，还剩下6天，every other morning指的是“隔一天的一天”，也就是说电话服务除了周日，都是隔天服务，周一没有，周二有，周三没有，周四有，周五没有，周六有...一周三早晨有，所以选D.

Answer 2

文中提到的The service is available there three mornings a week，意思就是说每周开通三个早晨。

答案D：every other morning except Sunday 除了周日每隔一天开一次,算一下其实也就是三天么，是和文中的意思一样哦`
