单选题
The current emergency in Mexico City that has taken over our lives is nothing. I could ever have imagined for me or my children. We are living in an environmental crisis, an air-pollution emergency of unprecedented severity. What it really means is that just to breathe here is to play a dangerous game with your health.
As patents, what terrorizes us most are reports that children are at higher risk because they breathe more times per minute. What more can we do to protect them and ourselves? Our pediatrician's (儿科医师的) medical recommendation was simple: abandon the city permanently. We are foreigners and we are among the small minority that can afford to leave. We arc here because of my husband's work. We are fascinated by Mexico--its history and rich culture. We know that for us, this is a temporary danger. However, we cannot stand for much longer the fear we feel for our boys. We cannot stop them from breathing.
But for millions, there is no choice. Their lives, their jobs, their futures depend on being here. Thousands of Mexicans arrive each day in this city, desperate for economic opportunities. Thousands more are born here each day. Entire families work in the streets and practically live there. It is a familiar sight: as parents hawk goods at stoplights, their children play in the grassy highway dividers, breathing exhaust fumes. I feel guilty complaining about my personal situation; we won't be here long enough for our children to form the impression that skies are colored only gray.
And yet the government cannot do what it must to end this problem. For any country, especially a developing Third World economy like Mexico, the idea of barring from the capital city enough cars, closing enough factories and spending the necessary billions on public transportation is simply not an option. So when things get bad, as in the current emergency, Mexico takes half measures--prohibiting some more cars from circulating, stopping some factories from producing--that even its own officials concede aren't adequate.
The word "emergency" implies the unusual. But when daily life itself is an emergency, the concept loses its meaning. It is human nature to try to adapt to that which we cannot change or to mislead ourselves into believing we can adapt.
单选题 According to the passage, the current emergency in Mexico City refers to ______ .
【正确答案】 A
【答案解析】[解析] 文章第一段中讲到“We are living in an environmental crisis,an air-pollution emergency of unprecedenmd severity.”我们正生活于一场环境危机中,生活在一个空气污染空前严重的非常时期。可见,墨西哥城目前的紧急情况指的是严重的空气污染。
单选题 Which of the following statements is NOT true according to the passage?
【正确答案】 C
【答案解析】[解析] 文章第二段第1句话说“因为孩子每分钟呼吸的次数更多,所以他们的危险更大”,可见A项正确;第3句话说“我们是外国人,……”,可见B项正确;第5句话说“我们为墨西哥着迷,为它的历史和丰富的文化着迷”,可见D项也正确。文中没有说作者丈夫的职业,只是说了儿科医师对他们的建议:永远离开这座城市,所以C项不对。
单选题 The word "hawk" (Paragraph 3) most probably means ______ .
【正确答案】 A
【答案解析】[解析] 文章第三段讲到,对于数百万的人来说,他们别无选择;全家人都在马路上干活,甚至生活也在这里;这种情形很常见——父母在交通指示灯下兜售物品时,他们的孩子就在长满草的公路隔离带上玩耍,呼吸着车辆排出的废气。可见,该词的意思应该是“出售”。
单选题 The Mexican government takes half measures to solve the pollution problem because ______ .
【正确答案】 A
【答案解析】[解析] 文章第四段中讲到:墨西哥政府不能实施控制空气污染的必要措施,因为对于墨西哥来说,控制首都足够的车辆、关闭足够的工厂以及在公共交通上投资数十亿必需的费用这样的想法是不可能的选择;当情况变严重时,墨西哥城采取折中办法——禁止更多的车辆运行、让一些工厂停止生产。由此可以看出,在墨西哥车辆和工厂占据着重要的地位,政府在空气受到污染时亦没有采取必要的措施来关闭和控制,只能做出折中选择。
单选题 The purpose of the passage is to ______ .
【正确答案】 C
【答案解析】[解析] 题目问的是作者写这篇文章的目的。从整篇文章来看:第一段作者讲到:墨西哥城正处在一种空气污染空前严重的状况下,人们的健康受到威胁。第二段讲到:作为父母,对孩子的担心。第三段讲到:对于数百万来这座城市挣钱的人,他们别无选择。第三段讲到:对于这个问题政府也不能采取更有效的措施。第四段:作者把这个问题上升到了人性的角度。因此整篇文章都说出了对空气污染极大的担忧。
