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. Like 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 a meeting on Monday, 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? Its for living a better life. Dirty air is definitely not a better life，”he said. China needs to develop its economy and invest(投资) in hightech. 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 Earth. What the public wants is a strong and beautiful China. The great efforts must be made to promote ecological progress and build a beautiful China. The words have shown the central governments resolution to address the environmental issue.【文章大意】文章谈到的是经济发展和环境保护之间的关系，我们需要经济发展，但不能以牺牲环境为代价。1The effect of smog doesnt include _.Athe rising of PM 2. 5 readingsBmore people suffering diseasesCthe increase of peoples incomeDpatients increased in hospital解析：C细节理解题。根据第一段中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 and heart diseases.烟雾引起PM 2.5指数的增加，患病的人增多，因而医院的病人增多，人们的收入的增加并不是由于烟雾的影响。2To make China stronger we have to develop economy, but _.Awe have to sacrifice air as the priceBthe dirty air is not what we wantCecological progress can be ignoredDthe smog is the only byproduct解析：B细节理解题。根据最后一段第一句What the public wants is a strong and beautiful China.我们为了使中国变得更加强大而发展经济，但是不能牺牲我们的空气质量。3The underlined word “they” in Paragraph 6 refers to _.Ahuman beingsBother plantsCspace technologiesDindustrial development解析：A词义猜测题。根据该句中的so that one day all human beings can migrate to the red planet because they have destroyed Earth.这里用代词代替前面出现的human beings。4From the last two paragraphs we can infer that _.Ahightech can completely solve the problem of pollutionBspace technologies should be developed in a large scaleCwe can move to the Mars after the Earth has been destroyedDwe must protect the environment while developing economy解析：D推理判断题。根据最后一句The words have shown the central governments resolution to address the environmental issue.可知当发展经济的时候我们要保护环境。.完形填空The green sea turtle is a large turtle.
