Hi, guys! I am having a hard time over here... in these sentences; a- It's difficult to study in a foreign country. b- ... and it's important to realize this fact. Why instead "to study" and "to realize" I cannot say "studying" and "realizing". Verb + adjective + infinitive? if so, why I can say both way these ones: I am happy to see you. I am happy seeing you. or It is nice to meet you. It is nice meeting you.

one this one, please. "... my making that score last Saturday was a reason for my family and me to celebrate." on my book is written just like the way above... but I was wondering if the best way would be ".... for my family and I to celebrate." grazie!

Hi everyone! Why " The first two movies I saw I kissed my girlfriend on her face and lips and so on..." and not "The two first movies I saw I kissed my girlfriend on her face and lips and so on..."
