Here are some examples:
* Me parece que hace frío. (It seems to me that it's cold.)
* Me parece que deberías ir al doctor. (I think you should go to the doctor.)
* Me parece que es una buena idea. (It seems to me that it's a good idea.)
The literal translation of "me parece que" is "it seems to me that," but it's more natural to say "I think that" in English.
