如果可以的话，我想告诉你我生活中发生的事情。If it is okay, I'd like to tell you about something that happened to me.

Is this sentence grammatically correct?  Is it a natural way to say it?  If not, please advise.

Hi everybody.  I'm new to this group.  Anyway...

As part of my studying strategy, I want to practice answering prefabricated questions such as these questions made for ESL students.  The problem is, I don't know of any lists of Mandarin questions out there.  Is anyone aware of such a list?

Thanks a bunch.

...between 在+verb and 正在 + verb?
