how to recite English words very effectively I found it's too easy to forget sometimes，how long did you spent on this？and do you have some useful techniques？

Cooking Does eveybody have an life experience like that if you were living or working in a community for a long time，maybe more than two years，you may be fed up with all the restaurants around that place，sometimes you even hate them，all the dishes just turn to be the horrible relatives，then you don·t want to contact them very frequently，because that，I used to cook by myself，I bought some cookbooks from the bookstore，and tried to find some techniques and details on the net，then I did some experiment，but sometimes I can·t find all those food material，or I am in a hurry，then I used to out of the regulations，I called them“fast-food”，today is Saturday，I am too lazy to do a sophisticated food，I just used some mushrooms and three eggs to made a pie for dinner.

Two questions I have been studying English formally for five months,but still when I talk with people use English,I am used to describe things use some simple or familiar words to build a sentence,and I think it`s a bad habit,although I have remembered some new words on purpose, but between the conversation，all the new words just disappeared from my mind，I just can not handled them. and there is another question,I found that when I talk with someone face to face,I can mainly understand what does he or she mean,but when I see a movie or a teleplay,I am so easy to get into confusion,are there many differences between the real dialogues and the moive dialogues?or just because my English is on a lower level,can you guys give some suggestions or some solutions?thank you.
