Prof. Mednick is a psychiatrist at the University of California. Her study involved the analysis of 77 adults. Each participant was given several wordassociated creative tasks. All tasks were given in the morning, with participants being shown a number of groups of 3 words, for example: cookie, heart and sixteen. They were asked to e up with a word that would be associated with all three given terms—like sweet. Sometime later, after some participants were allowed to sleep, they were asked to perform the same tasks and some new ones. It is worth mentioning that while some people slept, researchers used brain scans to see the type of sleep each participant entered. Researchers consider that sleeping on a problem in most cases leads to elucidation(解釋). They say when a person enters a phase called Rapid Eye Movement (REM) during sleep, it increases the effect. Such phase takes place right before we awake and according to scientists it helps our brain make links between unrelated subjects.3．閱讀理解故選D。不要成為那些不讀傳記的人群的一員。我發(fā)現(xiàn)好的傳記讓人放松。t be counted among their number.可知，首先，我覺(jué)得好的傳記很吸引人。 （4）考查推理判斷。故A選項(xiàng)作者認(rèn)為傳記閱讀令人愉快是正確的。的確，沒(méi)有什么事情比悠閑地度過(guò)夜晚，進(jìn)入另一個(gè)世界更令我放松。 （3）考查細(xì)節(jié)理解。故判斷出第三段劃線的other items指的是某個(gè)時(shí)期的故事。第一家商店吸引了你，但你會(huì)驚喜地發(fā)現(xiàn)，還有其它的商品吸引了你的注意力。根據(jù)第三段中的A good biographer tells not only the story of a person, but also of their times.
