【題目】判斷對錯(2X 5 = 10)
(1)D點的經(jīng)緯度是20度W,45度S ( )
(2)B點位于中緯度 ( )
(3)A點位于西半球和南半球 ( )
(4)C點位于D點的正南方向 ( )
(5)D點位于E點的東南方向 ( )
【答案】(1)×
(2)×
(3)√
(4)√
(5)√
【解析】(1)根據(jù)經(jīng)緯度的變化規(guī)律,緯度向北變大為北緯,用N表示,向南變大為南緯,用S表示;經(jīng)度向東變大為東經(jīng),用E表示;向西變大為西經(jīng),用W表示;那么D點的經(jīng)緯度是(20°E,50°N)。
(2)緯度劃分,0°~30°為低緯度地區(qū),30°~60°為中緯度地區(qū),60°~90°為高緯度地區(qū),所以B點位于低緯度。
(3)赤道---劃分南北半球的分界線;20°W和160°E---劃分東西半球的分界線(即從20°W向東到160°E為東半球,從160°E向東至為20°W為西半球),所以A點位于西半球和南半球。
(4)和(5)根據(jù)經(jīng)線指示南北方向,緯線指示東西方向判定:C點位于D點的正南方向 D點位于E點的東南方向。

【題目】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(快速眼動) 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.
【1】According to the article, which of the following is true?
