2015年10月16日，中国与印度尼西亚正式签署了共同建设和运营雅万高铁（雅加达至万隆）项目协议，标志着中国高铁走出去取得历史性突破。下图为雅万高铁示意图。此日，雅加达与上海相比（ ）A. 雅加达正午太阳高度更小B. 雅加达日落更晚C. 上海太阳高度日变化幅度更大D. 上海物影转动角度更大 答案：【答案】B【解析】因为10月16日，太阳直射点南移到赤道以南，雅加达纬度为南纬6度，上海位于北纬30度多，所以雅加达正午太阳高度角更大；上海太阳高度日变化幅度更小，故AC项错误。因为该日太阳直射南半球，昼长自南向北递减，雅加达比上海的昼长长，所以日落更晚；上海昼长短，物影转动角度Looking for a low-cost path to self-knowledge? A way to mine your subconscious① for clues to your motivations, desires and fears? No need to have years of treatment or analysis. Just look to your dreams. “You can ignore your dreams, but you are really doing harm to yourself,” says Lauri Quinn Loewenberg. “If so, you’re letting red flags pass you by, letting great ideas pass you by.” Some sleep researchers believe dreams are more directly related to our moods and emotions and can serve as tools to self-understanding. Dreams occur during the REM (rapid eye movement) cycles of sleep each night. For adults, that means about every 90 minutes. The first period of REM sleep may be short, 5 to 10 minutes, followed by longer periods, finally reaching an hour or more in the fourth or fifth period. When people are dreaming, brain scans show a lot of activities. The brain is online during dreams. The experiences you have during the day are connected during dream sleep. People we know or experiences we’ve had at different times in our lives may be different in the same dream. AmyBeth Gilstrap has had the same recurring② dream that annoyed her since Hurricane Katrina drove her and her daughter and friends out of New Orleans. Ms. Gilstrap says, “It is always spies. My job is to get people to some place.” She’s certain the dream is related to her effort in the hurricane to help several families leave. Sometimes her cats also are part of that dream. That’s because she went back into New Orleans, before it was allowed, to rescue her cats. Today, through brain scans scientists have known that the parts of the brain that control emotion and long-term memory are active during REM sleep. 1.
