Question

In recent years，smog has become a hot word all over China．For instance in January，Beijing saw only five days without smog．The rising PM 2.5 readings terrified many people，and some health experts said that whenever the smog gets serious，hospitals receive more patients suffering acute respiratory  （呼吸道的）  and heart diseases．
     Later，news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe．
      So the need to emphasize environmental protection while developing the economy is heard everywhere．
     Smog especially is a common concern．As a popular online post said，air may be the only thing that is equal for everyone．despite your income or vocation．People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices，but they breathe the same air as everyone else．
      At an important meeting，many representatives have expressed their concerns about the air quality，too．One talked about his experience in Beijing"After taking a taxi from the capital airport to my hotel，which took about an hour．I washed my nose and found the inside of my nose was black．We should ask ourselves this question：Why do we want to develop？It's for living a better life．Dirty  air is definitely not a better life．"he said．
     China needs to develop its economy and invest in  high-tech．Every Chinese wants a strong country．But without blue sky，clean water and safe food，the achievements in the economy will become meaningless．Space technologies are not to be developed for building a base on Mars so that one day all  human beings can migrate to the red planet because they have destroyed the Earth．
     What the public wants  is a strong and beautiful China．President Xi Jinping spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China．The words have shown the central government's resolution to address the environment issue．

Answer 1

68．B 细节理解题．根据第一段The rising PM 2.5 readings terrified many people，and some health experts said that whenever the smog gets serious，hospitals receive more patients suffering acute respiratory  （呼吸道的）  and heart diseases．可知雾霾导致了PM 2.5读数的上升，更多的人患上疾病，住进了医院．故选B．
69．C 细节理解题．根据第四段Smog especially is a common concern．As a popular online post said，air may be the only thing that is equal for everyone．despite your income or vocation．可知烟雾成为了一个普遍关注的问题，因为没人可以避免它．故选C．
70．A 推理判断题．根据倒数第二段可知中国需要发展经济，但是如果没有适合生存的环境，其他都毫无意义；再根据最后一段可知人们需要的是一个强大、美丽的中国．结合两段意思可推知，最后两段主要说的是在发展经济的同时要注意保护环境．故选A．
