Imaginitive story ;

Though it was in the middle of the day, the room was in complete darkness. Only silence filled the gloomy room.
A second later the comforter was rustled a bit and then a pale-looking girl came out. Her eyes were blank and her hair was all messed up. Blinking a few times, she drew (let out) a long sigh.

The girl was about to turn on the (lights?) switch of the room but then plunked down on the bed as if she ran out of any energy.
Through the window  a sound reached her ears  - kids' shouts, people's chatters, and birds' chirping.

Guided by instinct, when she drew the curtains aside, the sunlight flooded in. Her eyes grew misty as viewing the colorful and lively scenes, sitting still.

I really enjoyed reading this great imagination and the words you choose where really colorful!

on time simply - a good customer/ reliable customer not on time - poor customer/ unreliable customer something abit more idiomatic would be" getting him to pay is like beating blood out of a stone"

i will die, you can kill me and i still will not answer to a person like you answer to - give reasons for doing something so it means, i will not give you an answer because you are not important enough for me to need to

About Chinese food

I like Chinese food, especially hotpot, eating hotpot in the winter is really great. Chinese food is not only delicious but also nutritious. Food is cooked and tastes quite different in each province in China, I prefer to Chuan food which is a little spicy hot. Some food material ingredients can be cooked in many different ways, especially during the period of Chinese New Year, each family will make many varieties  types of food, all the relatives gather together and celebrate.This year I also tried some food from other countries but I like Chinese food the most.

Me too Chinese food is really delicious!!

some scientific words have interesting roots that can give you a good idea about the meaning of words particularly words with latin roots. one example is biology - anything with the ology ending mean study of. but yea id agree with the other guys to it could be confusing

both can be used in a situation like you walk into a room with friends "hey guys whats happening/ whats going on?" whats going on can be used if something is going wrong for example, something is on fire in the office " WHATS GOING ON?!?!" intonation can play a big part in how these phrases sound as well. you can make it condescending, questioning, surprised, angry etc....

Some i have come across - burning through cash - spending money quickly - pissing his(or her) money away - drinking too much and spending all your money on it
