Dreams

Studies show that in dreams things are seen and heard rather than thought. In terms of the senses, visual experience is present in almost all dreams; auditory experience in 40 to 50 percent; and touch, taste, smell, and pain in a relatively small percentage. A considerable amount of emotion is commonly present, usually a pure and single emotion such as fear, anger, or Joy.
Two clearly distinguishable states of sleep exist. The first state, called NREM-sleep (non- rapid-eye-movement sleep), occupies most of the sleep period and is associated with a relatively low pulse and blood pressure, and few or no reports of dreaming. The second type of sleep, known as REM-sleep ( rapid-eye-movement sleep) occurs cyclically during the sleep period with rapid eye movements and frequent dream reports. Typically, a person has four or five periods of REM-sleep during the night, whether the dreams are remembered often, rarely, or not at all; th
A. one, we "see" our dreams, and two, we "think" our dreams
B. one, we are happy, and two, we are angry
C. one, dreams put new information into our memories, and two, dreams have real meanings in pictures different from our logical thinking
D. we have pictures in dreams because one, we have slow eye movements, and two, we have rapid eye movements

[单项选择]There are plenty of studies which show that dogs act as social catalysts (催化剂), helping their owners forge intimate, long-term relationships with other people. But does that apply to the workplace Christopher Honts and his colleagues at Central Michigan University were surprised to find that there was not much research on this question, and decided to put that right. They wondered in particular if the mere presence of a dog in the office might make people collaborate more effectively. And, they found that it could.
To reach this conclusion, they carried out two experiments. In the first, they brought together 12 groups of four individuals and told each group to come up with a 15-second advertisement for a made-up product. Everyone was asked to contribute ideas for the ad, but ultimately the group had to decide on only one. Some of the groups had a dog underfoot throughout, while the others had none. After the task, all the volunteers had to answer a questionnaire on how they felt
A. We should have many dogs in the offices.

How many things can you see in the night sky A lot! On a clear night you might see the Moon, some planets, and thousands of sparkling stars. You can see even more with a telescope.
But scientists believe there are some things in the sky that we will never see. We won’t see them with the biggest telescope in the world, on the clearest night of the year. That’s because they’re invisible. They’re the mysterious dead stars called black holes.
As a star’s gases burn, they give off light and heat. But when the gas runs out, the star stops burning and begins to die.
As the star cools, the outer layers of the star pull in toward the center. The star squashes (挤压) into a smaller and smaller ball. If the star was very small, the star ends up as a cold, dark ball called a black dwarf. If the star was very big, it keeps squashing inward until it’s packed together tighter than anything in the universe.
Imagine if the E
A. ordinary
B. bright
C. strange
D. common
