萬籟俱寂，夜深人靜，窗外的細雨沙沙的打在梧桐樹上，遠方的親人不知過得還好不好。家鄉(xiāng)位于一個四面繞水的小島上，想想生我養(yǎng)我的母親河，童年的一幕幕映入腦?！x開故土故然心傷，然男兒志在四方，只是歲月匆匆，想起滔滔東逝的江水，不禁感嘆：逝者如斯夫。
I always say when I have more time，I'd like to catch up on spending more time with my girlfriend.
（譯文：我總是說當我有更多時間的時候，我要趕出多點的時間陪陪女友。）
是的，時間就像流水一般，失去的不再來，所以一定要catch up on something you have to do.這里catch up on something 意思就是“趕上某事，趕趕時間把某事完成”。 Catch up 這個片語大家可能都知道是追趕（come to; overtake）的意思。如：You have to work hard in order to catch up with the rest of the class.（譯文：你要用功以便追上班里其他人。）而catch up on something常指趕趕時間完成原本應該做而暫時沒有做的事情, it means to do what needs to be done because you have not been able to do it until now. Fox example:
Now, I need to catch up on cleaning my bedroom, reading as well. But I think, the most important thing is to catch up on sleep. That's the best bet.
（譯文：現(xiàn)在我需要打掃我的寢室，趕一趕要讀的書，但我想最重要的還是趕一趕睡眠，這是選擇。）
俗話說得好，時間就是袋子里的水，要靠擠才出得來.我們必須找出時間來catch up on something, 看看下面這個句子是如何說的。
It's not difficult to find extra time. I have the feeling if something to catch up on is truly important, the time to do may already be there, the only thing we have to do is to track the time down.
（譯文：找點額外的時間并不難，我有這樣的感覺：如果一些需要趕趕時間來完成的事情很重要，時間總是有的，我們要做的就是把它找出來。）
在這個例句中，我們又看到了另一個片語track something down它的意思是“追查、尋找某事”，track是“足跡”的意思，看到足跡就能追蹤到留下足跡的人或動物了，所以這個片語應該很好理解吧！這個片語也可以寫作track down something. To track someone or something down means to find them after a long difficult search, especially by following evidence that has been left behind.
讓我們看一看英文解釋：
Tracks are marks left in the ground by the feet of animals or people, or by the wheels of vehicles. If you track animals or people, you try to follow them by looking for the signs that they have left behind, like their tracks in the ground or other signs that they were there. To track someone or something down means to find them after a long difficult search as they didn't want to be found. For example, police track criminals down. Investigators track the truth down.
從上面這段話我們可以看出，這個片語主要指通過一些努力，克服一些困難或根據(jù)一些證據(jù)、線索而查到、找到。接下來再看兩個例子：
The police have tracked down the escaped convict.
（譯文：警察已追捕到逃犯。）
I always tried to track down different restaurants to eat Chinese food when I was abroad.
（譯文：當我在國外時總是盡力找些不同的地方品嘗中國菜。）
結束語：在這一講里，我們主要圍繞時間話題為大家介紹了兩個片語catch up on something趕上某事，往往有補充、補償?shù)囊馕对诶锩?，如趕作業(yè)，趕瞌睡等。第二個片語是track something down意思是追趕上某事、追查到某事。
