Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A, B, C and D. You should decide on the best choice and mark the corresponding letter on the Answer Sheet with a single line through the centre.
Passage One Air pollution can spread from city to city. It even spreads from one country to another. Some northern European countries have had “black snow”
from pollutants that have traveled through the air from other countries and have fallen with the snow. So air pollution is really a global problem. Air pollution can kill babies, older people, and those who have respiratory（呼吸的）diseases. As found in cities, air pollution increases the risks of certain lung diseases. Air pollution can cause both airplane and car accidents because it cuts down visibility（能见度）. There are other possible health dangers from air pollution that we don’t know much about. For example, scientists are trying to find out whether chemicals that reach us from the air may cause changes in our cells. These changes might cause babies to be born with serious birth defects. Scientists are trying to learn how all the many chemicals are apt（易于的）to take into our bodies from air, water, food, and even medicines act together to affect our health and the way our bodies work. That is another reason why it is so important to begin to control pollution now instead of waiting until we learn all the answers. Air pollution costs us a lot of money. It corrodes（侵蚀）our buildings. It damages farm crops and forests. It has a destructive effect on our works of art. The cost of all this damage to our government is great. It would be much more worthwhile, both for us and for the government, to spend our tax dollars on air pollution birth problems C. man’s behavior D. the nervous system 3.

Passage Two
Stiletto heels could be banned from the workplace because of health and safety reasons, according to British Trade Union bosses. The Trade Union Congress, predominantly male, has proposed a motion arguing that high heels are disrespectful to women while they also contribute to long term injuries. They propose instead that women wear “sensible shoes” with an inch heel limit in an attempt to avoid future foot and back pain as well as injuries. The motion is due to be debated at next month’s conference. The motion states: “Congress believes high heels may look glamorous on the Hollywood catwalks but are completely in appropriate for the day-to-day working environment. Feet bear the burden of daily life, and for many workers prolonged standing, badly fitted footwear,

and in particular high heels can be a hazard. Around two million days a year are lost through sickness as a result of lower limb disorders. Wearing high heels can cause long-term foot problems and also serious foot, knee and back pain and damaged joints. Many employers in the retail sector force women workers to wear high heels as part of their dress code. More must be done to raise awareness of this problem so that women workers and their feet are protected.”
Nadline Dorries, the Tory Member of Parliament, however criticized the motion and said the extra height heels give women can help them when in the workplace. “I’m 5ft 3in and need every inch of my Christian Louboutin heels to look my male colleagues in the eye,” she said. “If high heels were banned in Westminster, no one would be able to find me. The Trade Union leaders need to get real, stop using obvious sexist tactics by discussing women
