In the classroom,I read the para10-11.The word “shifted” in the first sentence of para11. puzzled me .In my mind, “shift”means change or move,but, in this sentence,it’s not the proper meaning.I read it again carefully,and still can’t understand the currect meaning.I must have to look it up in the dictionary.However,
I only have the electric dictionary nearby.So I decide to finish my work after coming back my dorm.
After returning my dorm,I continuing my work.I look it up in the LONGMAN ,there is a meaning interestes me.That means “to change a situation, discussion etc by giving special attention to one idea or subject instead of to a previous one”.I think I get it.In terms of narcissistic showoff,the purpose of them is to get admirition from other people.So the word “shift” here is vivid.Go on, “brooding darkly”also take me attention.In LONGMAN, “brood” means “keep thinking about something that you are worried or upset about” ,and “darkly” means “in a sad, angry, or threatening way”.So I can understand the sentense.The author observed the person carefully.
