A full moon slightly affects people's sleep, reports a Swiss team of scientists. Even people's sleep in a lab without windows experienced a small shortfall in sleep once a month. To test the moon's effect, 33 adult volunteers of both sexes and various ages spent several nights in a sleep lab. As they slept, researchers recorded their brain activity, eye movements and hormone levels. On nights closer to a full moon, the subjects took an average of five minutes longer to fall asleep, and slept for 20 minutes less. In addition, brain activity decreased by 30 percent during the sleep stage that the brain normally uses to recover from its daylight work. And levels of hormone that help control sleep cycles dropped. On these nights, the sleepers complained of poor sleep quality even though they were unaware of the moon's cycle. On the bright side, not a single participant turned into a werewolf. The Swiss team doesn't know how the moon affects sleep. The gravity of the moon causes ocean tides to rise and fall. But that force is too weak to affect sleep, Gajochen says. He believed some body's biological clock may be tied to the moon cycles. There may be another explanation, says David Dinges. This sleep researcher at the University Of Pennsylvania in Philadelphia says that the body clock is very sensitive to light at night. Volunteer's sleep could have been affected by exposure to extra moonlight before arriving at the lab. Question: The passage is mainly about _ . Options: A: the sleeping problems caused by the moon's cycles B: the influence of the moon on human sleeping habits C: the moon's effect on sleeping and its possible reasons D: the ways to improve sleep quality on a full moon night

Read the article and select the best answer. Article: A rainfores is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16degC.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere,warming the rest of the world .Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world. In the past hundred years, humans have begun destroying rainforests in search of three major resources : land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example,a lot of carbon dioxide in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit . There are two main reasons for _ . Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world' s wood supply. Rainforests are often called the world's drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests. Question: .What might be the best title for the text? Options: A: How to Save Rainforests B: How to Protect Nature C: Rainforests and the Environment D: Rainforests and Medical Development

Ques: Read the article and select the best answer. Article: The story began on a downtown Brooklyn street corner. An elderly man had fallen down while crossing the street , and an ambulance rushed him to the nearest hospital. There, when he came to now and again, the old man repeatedly called for his son. From a worn letter located in his pocket, an emergency-room nurse learned that his son was a sailor stationed in North Carolina Camp. Obviously there were no other relatives. Someone at the hospital called the Red Cross office in Brooklyn, and a request for the son to rush to Brooklyn was sent. Because time was short--the patient was dying, so they found the young man and rushed him to the airport in time to catch the only plane that night enable him to reach his dying father. It was dusk when the nurse took the tired, anxious sailor to the bedside. "Your son is here," she said to the old man. She had to repeat the words several times before the patient's eyes opened. The medicine he had been given because of the pain from his heart attack made his eyes weak and only saw the young man in uniform( ) standing outside the oxygen tent. He extended his hand. The sailor wrapped his strong fingers around the old man's, releasing a message of love and encouragement. The nurse brought him a chair, so the sailor could sit by the bed. Nights are long in hospitals, but all through the night the young sailor sat there, holding the old man's hand and offering words of hope and strength. It was nearly dawn when the patient died. The sailor placed his lifeless hand he had been holding on the bed, and went to inform the nurse. "Who was the man?" the sailor asked. "He was your father." the nurse answered surprisingly. "No, he wasn't," the sailor replied." I never saw him before in my life." "Why didn't you say something when I took you to him?" she asked. "I knew immediately there'd been a mistake, but I also knew he needed his son, and his son just wasn't here. When I realized he was too sick to tell whether or not I was his son, I guessed he really needed me. So I stayed." Two... Question: In the hospital _ .
