get on 的意思很多，要看语境才能准确翻译。get on 常有赶快做继续做（go on) 的意思。
例如：
-Hey, Li Hua, haven't see you for a couple of days. Do you have another draft of that application essay for me to check?（是啊，我们好几天没见了。 我一直忙著上课， 我的申请还没写好呢。）
-Well, you'd better get on it! It's due next week! （我得get on it，那是什麼意思？）
-I said, you'd better get on it. To get on it means to take care of something or start working on an important task. （噢， get on it就是动手处理某件重要的事情。 没错，没错，我的确该动手修改那申请书了。）
-That's right! You'd better get on it right away. By the way, I'm going to be busy on Thursday, so you'd better have it ready by noon tomorrow.（你星期四没有时间， 那就是说我非得在明天中午以前交给你。）
-Yes. If you can give it to me around noon tomorrow, I'll get on it right away and have the corrections ready by Thursday morning.（星期四上午你就能改完。那太好了。 谢谢你。 你知道吗？我现在千头万绪，忙得不可开交，我这个月的电话账单还没付呢。）
-Really? You'd better get on that! If you wait too long, they'll charge a big fee, and it might damage your credit score.（我知道，所以心里著急呢！过期不付要罚很多钱， 而且还会影响我的信誉。 这我都知道。可是我事太多， 我的汽车还没有重新登记呢。 ）
- What? If the police notice that you are driving a car with an out of date registration, you'll get a big ticket, or worse! You'd better get on that!
（是啊， 这件事一定得赶快办。 我可不想让警察发现我的车没登记，真要罚钱，我可受不了。可是我就是不喜欢填表， 要花很多时间。）
-That kind of thinking definitely won't cut it if you want to go to graduate school. Filling out forms for grant proposals is one of the main things that professors and graduate students do.
（那也是，研究生要申请研究经费都要填表。 看来我是得改变这种想法了。）
* 这段对话 get on it ， 意思是赶快处理。
