I agree, if you use 赶紧, it sounds a bit more polite than 快 which in this case is the major difference between the 2 usages.

Shouldn't it be 时间过去得很快? With 得 instead of 的? Thanks for the help anyway.

<p>赶紧 is an adverb and modifies the verb that follows it. It has the meaning of "hurry up to do something".</p>

<p>For examples, </p>

<p>赶紧走  hurry up and go</p>

<p>赶紧吃  hurry up and eat</p>

<p>赶紧跟她道歉 hurry up and apologise to her</p>

<p>快 in you example sentence functions as an adverb. It has the meaning of "do something quickly." </p>

<p>你们赶紧走吧 "Hurry up and go" and 你们快走吧 "go quickly" means essentially the same thing.</p>

<p>But the word 快, in other contexts, can also be an adjective, which you can modify using 很，太，非常, etc. </p>

<p>時間過得很快</p>

<p>時間過得太快</p>

<p>時間過得非常快</p>

<p>But you cannot do the same with 赶紧. This usage of 快 is very different from 赶紧.</p>

赶紧 is an adverb and modifies the verb that follows it. It has the meaning of "hurry up to do something".

For examples,

赶紧走 hurry up and go

赶紧吃 hurry up and eat

赶紧跟她道歉 hurry up and apologise to her

快 in you example sentence functions as an adverb. It has the meaning of "do something quickly."

你们赶紧走吧 "Hurry up and go" and 你们快走吧 "go quickly" means essentially the same thing.

But the word 快, in other contexts, can also be an adjective, which you can modify using 很，太，非常, etc.

時間過得很快

時間過得太快

時間過得非常快

But you cannot do the same with 赶紧. This usage of 快 is very different from 赶紧.

In the usage of the sentence `“你们赶紧/快走吧”`

Yes you can use both indiscriminately.

The only different between “赶紧” and “快” in the sentence above is the number of words.

* `赶紧` means you have to do it now
* `快` got other usage but one of them is same as `赶紧`

In my opinion, if I have to use `快` in the above sentence it would be like I'm shouting `快走吧！！` shorten the number of sounds I have to pronounce.

Then I will use `赶紧` in the above sentence it would be like I'm talking gently `你们赶紧走吧`

There are excerpts from The Contemporary Chinese Dictionary,which is authority of the Chinese language.

First，We talk about the discussion of answer above.
Though 'fast' and 'past' can be translated respectively as 快的 and 过去的, in Chinese, no expression like 时间过的真快.


As the dictionary says in Interpretation 3: 的 used after a predicate verb to emphasize the perpetrator,time,place or method and the usage is only legal in past tense.
For 得，in interpretation 3: used after verb or adjective to express the result or extent.

If we directly translate the sentence into English:
时间  过      得  真        快
Time passed     really   fast

得 has no corresponding translation.
Noticeably, both of them is light tone in the circumstance.
In addition , in some ROC period or earlier literatures we can see they used 的 instead of 得.
Okay,let's talk about 赶紧 and 赶快.

They both are adverb, the prior means seize the opportunity firmly, without any delay and the later means to seize the opportunity,speed up.

In an emergency, we use 赶紧 more, such as 赶紧走！(Go quickly!),赶紧加工（Accelerate the process of machining）.
In some situations we also use 赶快: 赶快，否则你会迟到！（Hurry up, or you'll be late!），赶快上车（Get on quickly）。
