【题目】判断对错(2X 5 = 10)
(1)D点的经纬度是20度W,45度S ( )
(2)B点位于中纬度 ( )
(3)A点位于西半球和南半球 ( )
(4)C点位于D点的正南方向 ( )
(5)D点位于E点的东南方向 ( )
【答案】(1)×
(2)×
(3)√
(4)√
(5)√
【解析】(1)根据经纬度的变化规律,纬度向北变大为北纬,用N表示,向南变大为南纬,用S表示;经度向东变大为东经,用E表示;向西变大为西经,用W表示;那么D点的经纬度是(20°E,50°N)。
(2)纬度划分,0°~30°为低纬度地区,30°~60°为中纬度地区,60°~90°为高纬度地区,所以B点位于低纬度。
(3)赤道---划分南北半球的分界线;20°W和160°E---划分东西半球的分界线(即从20°W向东到160°E为东半球,从160°E向东至为20°W为西半球),所以A点位于西半球和南半球。
(4)和(5)根据经线指示南北方向,纬线指示东西方向判定:C点位于D点的正南方向 D点位于E点的东南方向。

【题目】A
Do you remember your dreams? Do people have the same dreams? Why do I dream?
There are many questions about dreams. We dream during the REM(快速眼动) stage of sleep. We have about five periods of REM sleep during the night. The first REM cycle(周期) lasts about 10 minutes. As the night goes on, the REM cycle gets longer. By early morning, the REM cycle can last up to 90 minutes. Usually, it is in this last REM cycle that we remember our dreams.
Dreams change as people age. People may have several dreams each night. Some are like films and usually in color. They come to us over and over again. That may be because the dreamer is worrying about something and trying to find the answer. Sometimes we wake up with a good feeling from a dream. But often we can’t remember the dreams clearly.
It is reported that too much dreaming is bad for our health. The more we sleep, the longer we dream. The mind is hard at work. That is why we may have a long sleep and still feel tired when we wake up.
Do you feel a little sleepy after lunch? Well, that’s normal. Your body naturally slows down then. What should you do about it? Don’t drink coffee, take a nap, instead. There are many advantages of a daily nap. First of all, you can remember things better and make fewer mistakes. Also, you can learn things more easily after taking a nap. A 20-minute nap can reduce your pressure. Finally, a nap can make you cheerful.
But, there are some simple rules you should follow about taking a nap. First, take a nap at noon, about eight hours after you wake up. In general, a 20-minute nap is the best. If you sleep longer, you may fall into a deep sleep. After waking up, you will feel worse. Also, you should set an alarm clock. That way, you can fully relax during the nap. You don’t have to keep looking at the clock so that you don’t oversleep. Now, next time you feel sleepy after lunch, don’t get stressed. Put your head down, close your eyes and take a nap.
