13．Air pollution is a leading cause of cancer and classified among Group 1，or top，human carcinogens （致癌物质），said the International Agency for Research on Cancer （IARC），which is the World Health Organization's （WHO） cancer agency，on Oct 17，2013．
The most widely used system for classifying carcinogens comes from the IARC，which places them into five groups．Group 1carcinogens definitely cause cancer in humans．Group 2A is probably carcinogenic to humans，Group 2B is possibly carcinogenic，the carcinogenicity of Group 3in humans is unclassifiable，and Group 4is probably not carcinogenic to humans．Only a little more than 100are classified as Group 1cancer-causing substances，including ultraviolet radiation and tobacco smoke．
"Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants，"the lARC's Dana Loomis said in a statement．"The results from the reviewed studies point in the same direction：the risk of developing lung cancer is significantly increased in people exposed to air pollution．"
In 2010，lung cancer resulting from air pollution killed 223，000people worldwide，and there was also convincing evidence that it increases the risk of bladder （膀腕） cancer，according to the IARC．
Air pollution is already known to raise risks for a wide range of illnesses，including respiratory and heart diseases．
Air pollution is global，although the levels of it vary over space and time．
Loomis said people in Asia，eastern North America，some places in Central America and Mexico，as well as North Africa have relatively high exposure．Developing countries with large populations and booming manufacturing sectors，such as China，are particularly at risk．
Many cities in China，such as Beijing，frequently see smog．This week，Harbin，the capital city of Heilongjiang province，became the first Chinese city to officially suspend classes due to serious smog
Many developed countries face similar problems，although to a lesser degree than most developing nations．In Europe，levels of many pollutants have fallen．But between 91and 96percent of Europeans living in cities are exposed to levels of PM2.5-tiny particles with a diameter of less than 2.5micrometers-that are higher than the WHO safety limits，says a report published by the European Environment Agency on Oct 15．
Although both the composition and levels of air pollution can vary dramatically from one location to the other，the 1ARC said its conclusions apply to all regions of the world．
"Given the scale of the exposure affecting people worldwide，this report should send a strong signal to the international community to take action without further delay，"said Christopher Wild，director of the IARC．

59．What might be the best title of the passage？C
A．Signals of air pollution
B．Safety limits of air pollution
C．Air pollution，cancer risk
D．Air pollution，smog risk
60．What's the main task of IARC？B
A．To focus on cancer-causing substances．
B．To evaluate the air quality．
C．To study the developing risk of cancer．
D．To send signals to the international community．
61．Why should the international community take action without further delay？D
A．The composition and levels of air pollution vary from place to place．
B．More and more people in developing countries are exposed to air pollution．
C．Developed countries face air pollution，the level of which is higher than the safety limits．
D．A large number of people worldwide are exposed to air pollution．

9．People who do not get enough vitamin A in their diet may develop night blindness．But in the developing world a lack of vitamin A causes much more serious harm to children．The World Health Organization links the lack of vitamin A to as many as 250.000 child deaths every year．

   Dan Gustafson heads the Washington office of the United Nations Food and Agriculture Organization． He points toefforts in the past to increase the popularity of other nutritious crops． He says most of these efforts failed because organizers of the campaigns did not consider what people wanted to eat．But Mr．Gustafson sees a better chance for the efforts to increase the popularity of the orange sweet potato in Africa． For one thing，except for the color，the vegetable is similar to what people already use．

16．Why are people interested in eating raw foods or whole foods？One reason is that eating these types of food reduces the risk of acid accumulation in your body．
Raw and whole foods are usually digested more efficiently than cooked and refined foods．When we cook foods，we destroy the natural enzymes（酶）that are part of the food in its raw form．These enzymes were intended by nature to help us digest the food．When we consume food without these natural enzymes，our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream．In both instances，the result is obesity．When too many nutrients are absorbed at once，the body grows fat．Improperly digested food moves slowly through the digestive tract，where it becomes increasingly acidic （酸性的）．To protect its vital organs from this acidic waste，the body changes the acid into fat and stores it safely away from the organs．
Processed foods contain chemical elements，which might confuse the appetite mechanism that tells us when we've had enough to eat； as a result，people often overeat．Processed foods also upset the digestive cycle．The body will either identify these foods as allergens and then store them safely away from the organs as fat，or the remains of undigested food will become acidic and enter the bloodstream as acid waste，which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body's cells．The body's metabolism（新陈代谢） becomes inactive，and the result is weight gain and obesity．
The accumulation of acid in the digestive tract makes digestion increasingly inefficient．When that happens，even healthy foods can become acidic and the food allergies will become more common．
To stop this vicious（恶性的） circle in its tracks，people need to consume food and supplements that will neutralize （使…中和）the acid already accumulated in body．Eating the right types of raw and whole foods can help．It's also important to restore your enzyme balance．You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production．If you truly want to change and help your body heal itself，you need to take an active approach．-Raw and whole foods can be your choice．

31．What is the main purpose of this passage？A
A．To advocate eating more raw and whole foods．
B．To tell the differences between raw and processed foods．
C．To inform people of the harm of processed foods．
D．To warn people of the problem of obesity．
32．It can be inferred from Para.2thatB．
A．it is essential for people to protect their vital organs
B．foods with natural enzymes help people keep fit
C．we'd better be cautious about raw and whole foods
D．giving up cooked and refined foods is a new lifestyle
33．Processed foods are unhealthy because theyC．
A．destroy body's cells
B．are difficult to digest
C．may lead to obesity
D．stop body's metabolism
34．What is likely to be talked about following the last paragraph？D
A．Active approaches to avoid acid．
B．Different causes of acid accumulation．
C．Correct ways to cook raw foods．
D．Suitable types of raw and whole foods．
35．What can we learn from the text？B
A．Processed foods are good for our appetite mechanism．
B．Eating the right types of raw and whole foods does good to our body．
C．The accumulation of acid in the digestive tract makes digestion more effective．
D．Processed foods also comfort the digestive tract．

Men are also living far longer，although their numbers are far fewer．There were an estimated 92male centenarians in 1961and just below 2，000in 2010．
