1. What's the difference between "go over" and "observation"?
2. I'm reading a story book. I want to describe character's personality. Can you tell me about common expessions in detail?
#1 "Go over"
is a verb. It means to study or peruse something. For example, "I should go over
my science textbook one more time before the test tomorrow".
is a noun. It is something you have seen or noticed. For example: "On her trip to the zoo, she wrote down her observations
about the size, shape, and habits of the animals she saw".
I'm not sure I understand what you need. Are you looking for vocabulary that can be used to describe a person's character or personality? Here are some good websites with personality vocabulary and definitions: http://esl.fis.edu/vocab/q1/f-char1.htm http://esl.fis.edu/vocab/q1/f-peop2.htm
I hope this helps you.
