你认为做什么事的时候时间过得最快: Could some explain the meaning of this sentence
Is this sentence easier to understand now?
你认为：做什么事的时候，时间过得最快？
时间过得最快 =&gt; Time passes the fastest. This is relatively easy to parse, I reckon.
The first part of the sentence is trickier. &quot;X的时候&quot; means &quot;when X&quot;. At first glance X seems like it might be the whole 你认为做什么 clause or only 做什么. But 认为 is used to talk about one's opinion, so 你认为做什么 as a standalone clause doesn't make sense. That means &quot;做什么事的时候&quot; (&quot;when doing what thing&quot;) is correct; and the question is &quot;What is it that when you do it time flies the fastest?&quot;
An answer to this question would be 我认为玩电脑的时候时间过得最快 (I think time flies the fastest when (I'm) playing computer games).
