But for scientists, working out what is going on in an actor39。 Now, researchers have said actors show different patterns of brain activity depending on whether they are in character or not. almost like the character is possessing you. Once inside the MRI scanner, the actors were asked to answer a number of questions, such as: would they go to the party? And would they tell their parents that they had fallen in love? The results revealed that the brain activity differed depending on the situation being tested. The team found that when the actors were in character, they use some thirdperson knowledge or inferences about their character. However, Philip Davis, a professor at the University of Liverpool, was unimpressed by the research, saying acting is about far more than pretending to be someone — it involves embodying (體現(xiàn)) the text and language.（1）How did Dr Brown39。By scanning the brain activity of some actors.B.By interviewing some theatre teachers.D.s research?

The data included brain scans, which the researchers used to look for visual signs of reduced glucose uptake（葡萄糖吸收）.It is an objective marker of the sort of reduced brain function that goes along with expected, glucose uptake was reduced in those with AD. What the researchers also discovered was that glucose uptake was reduced in those with mild cognitive damage who also showed evidence of reduced illness awareness. Finally, the researchers found that those who had reduced illness awareness were more likely to develop AD than those without.（1）What can be implied from paragraph 1？ A.The memory of the young is better than the old.C.s disease.D.s a rare phenomenon when young people forget something.（2）What statement does the researchers in the new study agree with?
