sometimes 放前面要加逗號嗎?

Question

I go to the department store sometimes.

可以把sometimes 移到前面變成:

Sometimes I go to the department store. ??????????????????

或是

Sometimes , I go tho the department store. ????????????????//

或是
I sometimes go to the department store???????????????????

Answer 1

不用加逗號!!
所以用第一句" Sometimes I go to the department store. " 就可以了!!
因為sometimes屬於頻率副詞,所以也可以放在be動詞後 或 一般動詞前,所以可改成:
I sometimes go to the department store. ( 一般動詞前 )
I am sometimes late for school. ( be動詞後 )

Answer 2

我覺得I sometimes go to the department store.
比較常用
