every Sunday 与 on every Sunday 的用法

问题描述

every Sunday, every Monday, every Tuesday 等，肯定是没有问题的：

I go to church every Sunday. 我每星期天都上教堂做礼拜。

The rubbish is collected every Tuesday. 垃圾每星期二收走。

但可以用 on every Sunday, on every Monday, on every Tuesday等吗？因为在某体的某一天，英语习惯上是用介词 on 的，这里的介词 on 是被省略了，还是习惯上就不能用？

老师答疑

陈老师：

▲张道真与温志达合编的《英语语法大全》在1637节指出：……从理论上可以看作是介词短语，其中 at, on 或 in 省略：

He came (in) every year.

He left (on) last Sunday.

We shall meet (at) next Christmas.

▲但夸克等人在《英语语法大全》中则认为下面的句子是对的：

Every Sunday we usually go for a walk.

但下面一句则是不可接受的：

* On every Sunday we usually go for a walk.

▲所以，你作为学生最好是这样来理解：on every Sunday,on every Monday, on every Tuesday 等表达中的介词 on 是必须要省略的。

谢谢陈老师的解答！
