Question

谁来帮我看一篇阅读啊，高中英语

Have you ever had the strange feeling that you were being watched? You turned around and，sure enough，someone was looking right at you!
Some parapsychologists(心理学家)say that humans have a natural ability to sense when someone is looking at them．To study whether such “a sixth sense” really exists．Robert Baker，a psychologist at the University of Kentucky，performed several experiments．
In the first one，Baker sat behind unsuspecting people in public places and stared at tile backs of their heads for 5 to 15 minutes．The subjects were eating，drinking，reading，studying，
watching TV，or working at a computer．Baker made sure that the people could not tell that he was sitting behind them during those periods．Later，when he questioned the suspects，
almost all of them said they had no idea that someone was
staring at them．
For the second experiment，Baker told Subjects that they would be stared at from time to time from behind a two-way mirror in a lab setting．The people had to write down when they felt they were being stared at and when they weren’t．Baker found that the Subjects were no better at telling when they were stared at than if they had just guessed．
Baker's experiment concludes again that people do not have the ability to sense when they are being stared at．If you doubt the outcome of his two experiments，I suggest you repeat the experiments and see for yourselves．

In the second experiment,the subjects________.
A.could tell when they were stared at and when they weren't
B.could tell when they were stared at but couldn't tell when they weren't
C.couldn't tell when they were stared at but could tell when they weren't
D.couldn't tell when they were stared at or when they weren't

Answer 1

翻译：
在第二段的第一个实验中，那些受试者们_____。
A.能够分辨出他们是否被盯着
B.能够分辨出他们何时被盯着但不能分辨出什么时候没被盯着
C.和B相反
D.不能分辨出他们是否被盯着

由文中可知，他们根本不存在所谓的第六感，他们没法知道是否被人看着，只是人们一直以来的错误认识
【have no idea可以看出】
