the other day 的用法
这是一个短语，意思是“几天前”，等于a few days ago. 有时也指过去不确定的某一天。
我们还可以说：the other night, the other week, etc.
Examples:
1. I fell across a friend of mine in the Friendship Department Store the other day.
前几天我在友谊商店偶然遇见了我的一位朋友。
2. I saw your friend the other day.
前几天我看到过你的朋友。
3. I am calling about what we discussed the other day.

7. As we reported the other day, Dell shut its general customer forums.
8. The other day I called my classmate,and he said that he was ill in bed.
9. It was Mary and Dick who gave me these things the other day.
[附] 偶尔我们也能见到 in other day 的说法，它不能算作是短语，相当于中文的“换一天”、“改天”吧，用在一般将来时的句子里。
Cannot help doing sth. 的用法
该短语的意思是：“禁不住做某事”。
例如：
1、When he heard the news, he couldn't help crying.
当他听到这个消息时，禁不住哭了起来。
2、Have a lot of doubt, he can not help asking them question.
因为他有些疑问，他禁不住向他们提问。
3、She can not help smiling.
她禁不住微笑起来。
4、She cannot help eating up the whole bucket of ice-cream.
她控不制自己，把整个冰淇淋都吃掉了。
5、I can not help think the same.
我不禁也有同样的想法。
但是要注意，如果can't help后接的不是动名词，那么，这里就是一般的否定句式，help仍然要翻译为“帮助”。
例如：
1、But one hundred and ninety is their final bid. I can not help it.
但190美元是他们的最终出价，我也没有办法。
2、Mum, I'm so busy .So I can't help to clean the room today.
妈妈，我很忙。所以，今天我不能帮你打扫房间了。
