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`
