【題目】閱讀材料，回答問題．
材料一：20世紀90年代以來，中國的老齡化進程加快．65歲及以上老年人口占總人口的比例由1990年的5.57%上升到2000年的6.96%，目前中國人口已經進入老年型．預計到2040年，65歲及以上老年人口占總人口的比例將超過20%．同時，老年人口高齡化趨勢日益明顯。
（1）讀材料一，我國人口面臨的問題是： ． 為了緩解此問題我國于2015年10月29日已正式啟動政策．
（2）請你結合材料談一談，我國人口老齡化有哪些特點？（二點即可）
（3）上述我國人口問題帶來的社會問題有（一點即可）
【答案】
（1）人口老齡化；全面二胎
（2）老年人口數量大；老年人口增長快
（3）勞動力短缺．
【解析】進入新世紀以來，我國人口老齡化速度明顯加快，老齡化問題日趨突出，這是不可回避的事實，計劃生育是我國的基本國策，近期內穩定低生育水平仍是解決我國人口問題的主要對策，提高城市人口的比例不是解決人口老齡化的根本措施，我國人口老齡化加快，帶來社會養老負擔加重，勞動力短缺．因此，積極、妥善解決人口老齡化問題是正確合理的對策．（1）讀材料一，我國人口面臨的問題是：人口老齡化．為了緩解此問題我國于2015年10月29日已正式啟動全面二胎政策．（2）根據材料談一談，我國人口老齡化的特點有老年人口數量大，老年人口增長快等．（3）上述我國人口問題帶來的社會問題有勞動力短缺、養老負擔加重等．（4）我國人口老齡化加快，帶來社會養老負擔加重，勞動力短缺等．所以答案是：（1）人口老齡化；全面二胎．（2）老年人口數量大；老年人口增長快；（3）勞動力短缺．

【題目】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 anap, 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?
A. People always ask questions in their dreams.
B. People never dream in their last REM cycle.
C. The first REM cycle is the shortest of the five.
D. It’s impossible for people to remember their dreams.
【2】According to the article, why do people sometimes have the same dream again and again?
A. Because they are worried about something.
B. Because they often watch interesting color films.
C. Because they want to remember the dream clearly.
D. Because other people ask them too many questions.
【3】The underlined word “nap” in Paragraph 5 most probably means “___________”.
A. A long walk B. a kind of drink
C. a short sleep D. a deep sleep
【4】According to the article, which of the following is not an advantage of a daily nap?
A. We can run much faster.
B. We can learn things more easily.
C. We can become happier.
D. We can remember things better.
【5】According to the article, which of the following is true?
A. Dreaming is harmful to our health.
B. The longer we dream, the better we sleep.
C. We should fall into a deep sleep after lunch.
D. We’ll feel better after a 20-minute nap at noon.
