第1题,1. By 1994 the young Einstein had gained world fame. He accepted the offer to become a professor at the Prussian Academy of Science in Berlin. He had few duties, little teaching and unlimited opportunities for study, but soon his peace and quiet were broken by the First World War. Einstein hated violence. The misery of war affected him deeply, and he sat unhappily in his office doing little. He lost interest in his research. Only when peace came in 1918 was he able to get back to work.
In the years following World War I honors were increasingly heaped on him. He became the head of the Kaiser Whihem Institute of Theoretical Physics. In 1921he won the Nobel Prize, and he was honored in Germany until the rise of Nazism when he was driven from Germany because he was a Jew.

An attempt to study this was made by two researchers using a series of silent films. They had two actors play the parts of an executive (经理) and a visitor, and switch roles each time. The scene had one man at his desk playing the part of an executive, while the other, playing the part of a visitor, knocks at the door, opens it and approaches the desk to discuss some business matter. The audience watching the films was asked to rate the executive and the visitor in terms of status. A certain set of rules about status began to emerge from the ratings. The visitor showed the least amount of status when he stopped just inside the door to talk across the room to the seated man. He was considered to have more status when he walked halfway up to the desk, and he had the most status when he walked directly up to the desk and stood right in front of the seated executive. A. B. how to tell the differences between an executive and a visitor A. C. A study revealing a set of rules about the status of businessmen. A. C. the lower his status &n
The experiment revealed that people who were unable to dream became nervous, easily upset, and hungrier. As soon as they were able to sleep without interruptions they lost their nervousness and became normal again; however, they then had more dreams than usual. It was as if they were catching up on their dreams.
To check these findings, the researchers carried on a control experiment. Again they woke people during the night, but during non-dreaming periods. These people did not change their daytime behavior. And when they were allowed to sleep without interruptions (打断), the number of their dreams did not increase.
Experiments like these have caused scientists to ask if dreams serve a purpose. Researchers know, for example, that some people who go for days without sleep will suffer from hallucinations (幻觉). Certain people even begin to show signs of mental illness. Some researchers believe that people become this way because they cannot have their usual numbers of dreams. According to this theory dreaming helps people to lead normal lives.
Another thing that affected the status of the visitor in the eyes of the observers was the time between knocking and entering. For the seated executive, his status was also affected by the time between hearing the knock and answering. The quicker the visitor entered the room, the more status he had. The longer the executive took to answer, the more status he had.
C. how to tell businessmen at a glance
D. how businessmen indicate status
D. It is a good method to use a series of silent film in research. A. C. the more it affected his status D. the higher his status
