We can use the present perfect and the present perfect continuous to talk about actions, unfinished actions that started in the past, and are still true now.

我们可以用现在和现在进行谈论动作，从过去开始的未的但现在仍然进行的动作。

Now 'gone' is the one to use when it's an unfinished action that started in the past and affects the present moment.

而谈论开始于过去的、未的并影响现在的动作，用“gone”。

So these are three common phrases that you can use with the present perfect when you are talking about unfinished time, again, from the past until now.

所以这个常用的短语，你可以用它们在谈论从过去到现在为止的未间使用现在。

The present perfect is used here because the action, visiting Paris, happened at some point in the past, and it is still relevant to the present.

此处使用现在，因为“参观巴黎” 这一行为发生在过去的某个刻，且至今仍与现在相关。 虽然具体参观间未明确指出， 但重点在于截至目前为止的体验。

Now, this is especially important when we are talking about unfinished time, from a time in the past until now.

现在，当我们谈论从过去某个间直到现在的未间，这一点尤其重要。
