试题解析

肾囊肿

肾囊肿是成年人肾脏最常见的一种结构异常,可以为单侧或双侧,一个或多个,直径一般2cm左右,也有直径达10cm的囊肿,多发于男性。随着年龄的增长,发生率越来越高,单纯肾囊肿一般没有症状,只有当囊肿压迫引起血管闭塞或尿路梗阻时可出现相应表现,有可能对肾功能产生影响。当囊肿超过5cm,应进行相应的治疗,包括囊液抽吸术并囊内注射硬化剂或行手术治疗。我们通常见到的肾脏囊肿中,大多数是单纯肾囊肿,而遗传性肾脏囊肿性疾病所占比例相对较小。小于20岁者几乎没有单纯性肾囊肿,如果小于20岁的个体出现囊肿,要高度怀疑肾脏先天发育问题或遗传性肾脏囊肿性疾病。随着年龄的增长,肾囊肿的发生率越来越高,30~40岁间单纯肾囊肿的发生率为10%左右,到80岁时,单纯性肾囊肿的发生率达到50%以上。单纯肾囊肿多发于男性。

Passage 1People often complained about not getting"a good night's sleep", but sleep patterns differ from person to person. Most adults require six to eight hours of sleep to function well, while others survive on only a few hours. Still, most people today think of sleep as one continuous period of downtime. This is not the way people used to sleep. According to researchers in earlier times, people divided sleep by first sleep a few hours, waking up, then going back to sleep.Before the 18th century, people had no gas or electricity in their homes. Fire, candles, or oil lamps were the common forms of lighting. This lack of artificial lighting in homes contributed to people's sleep patterns. It made sense for people to go to bed early. If you live in this time period, you might be a hard-working farmer, and you would come home, eat and quickly fall into bed exhausted. You would probably go to sleep at 9:00 or 10:00 P.M. In this first period of sleep-called first sleep-you would typically sleep until midnight or shortly afterwards.Halfway through the night during a period some call the watch, or watching period. When you came out of first sleep, you would stay in bed and relax quietly. You might talk with a bedfellow, meditate on the day's events or the meaning of a dream, or just let your mind wander. If you enjoyed writing or drawing, you might get out of bed to write a poem or story or draw a picture.Then you would start to feel sleepy, so would return to bed and fall asleep again for your second sleep. This period would continue until early morning when daylight arrived. Again, with no artificial lighting in homes, people naturally woke up early to take advantage of sunlight.Today, human may consider divided sleep a strange habit, but sleep researchers say that it is actually a more natural sleep pattern. Dr. Thomas Wehr of the U.S. National Institute of Mental Health has studied human sleep. He thinks that modern sleep problems occur because the orderly, natural way of sleep is breaking through the more recent continuous sleep pattern. Wehr and other scientists believe that artificial lighting has altered the way people sleep. In a research study, he asked 15 adults to rest and sleep in darkness for 14 hours(from 6:00 P.M. to 8:00 A.M.). At first, the subjects took a few hours to get to sleep, and then slept 11 hours a night. Then overtime, they switched to divided sleep. They fell asleep for about 3 or 5 hours in the evening, stay awake for an hour of two and the slept again for four hours till early morning.Unlike the people in the study, we modern humans generally do not practice divided sleep. However, many of us have the experience of waking up in the middle of the night. We usually consider this a sleeping "problem", but perhaps we should look at it as natural behavior. Divided sleep may be the way we should all be sleeping.A first sleep followed by a relation period and a second period of sleep could help all of us to beat the stress of our fast-paced lives.What conclusion does the writer make about divided sleep?
