Group 1 carcinogens definitely cause cancer in humans. Group 2A is probably carcinogenic to humans, Group 2B is possibly carcinogenic, the carcinogenicity of Group 3 in humans is unclassifiable, and Group 4 is probably not carcinogenic to humans. Only a little more than 100 are classified as Group 1 cancer-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 lARCs 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 2020, lung cancer resulting from air pollution killed 223,000 people 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 smogMany developed countries face similar problems, although to a lesser degree than most developing nations. In Europe, levels of many pollutants have fallen. But between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5tiny particles with a diameter of less than 2.5 micrometersthat 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.1、What might be the best title of the passage?ASignals of air pollutionBSafety limits of air pollutionCAir pollution, cancer riskDAir pollution, smog risk2、Whats the main task of IARC?ATo focus on cancer-causing substances.BTo evaluate the air quality.CTo study the developing risk of cancer.DTo send signals to the international

D由 (2020山东临沂高三一模)改编Children will find it more difficult to buy cigarettes as vending machines(自动售货机)selling tobacco will be officially banned in England today.According to the British Heart Foundation(BHF),around 200,000 young people start smoking regularly in England each year and 11 percent of 11-to-15-year-old regular smokers in England and Wales get their cigarettes from vending machines.Betty McBride, Director of Policy and Communications at the British Heart Foundation,said,“Thousands of children who are at risk of addiction regularly get tobacco from these machines,which of course,dont ask them to prove their age.With the tobacco industry increasingly depending on young smokers to keep their profits,theyre fighting tooth and nail to stop any changes that might hit their bottom line.”The ban, which makes it illegal to sell tobacco from vending machines and requires shopkeepers to ensure all tobacco advertising on the machines is removed,comes into force in England today.It is the first ban in Europe to prohibit selling cigarettes from vending machines,which shows the determination of England to fight against smoking.Other measures to protect young people from the dangers of smoking are also on the way.In April 2020 large retailers(零售商)in England and Scotland will have to get rid of all tobacco displays and small shops will be expected to do that from April 2020.Wales and Northern Ireland also plan to make similar regulations.The UK Government is due to begin a public consultation before the end of the year on whether to introduce plain packaging for cigarettes which would reduce their marketing appeal to young people,help to make health warnings more effective and,alongside other measures,help to reduce the number of smokers in the long term.9.According to the text,vending machines selling cigarettes.A.offer cheaper productsB.have more varieties of productsC.dont check buyers personal informationD.keep a record of every

year.Unfortunately，the water there is far too deep for even the tallest windmills(see picture)to touch bottom. An experiment under way off the coast of Norway，however，could help put them anywhere.The project, called Hywind，is the worlds first largescale deepwater wind turbine(涡轮发电机)Although it uses a fairly standard 152ton,2.3megawatt turbine，Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture)，a technology Hywinds creator，the Norwegian company StatoilHydro，has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cables(缆索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves.Hywinds stability(稳定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but its difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spars centre of gravity must be moved much closer to the oceans surface. To do that, the company plans to design a new kind of wind turbine, one whose gearbox(变速箱) sits at sea level rather than behind the blades(see picture)Hywind is a test run, but the benefits for perfecting floating windfarm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing off shore windmills are planted. Deepsea farms are invisible from land, which helps overcome the windmillaseyesore objection. If the technology catches on, it will open up vast areas of the planets surface to one of the best lowcarbon power sources available.本文为科普短文，讲述世界上第一个深海风力发电机涡轮发电机以及它的发电原理及好处。9The Hywind project uses totally new technology to ensure the stability of_.A. the cables which tie the spar to the ocean floorB. the spar which is floating in deepsea waterC. the blades driven by strong and steady sea windD. the stones filled in the spar below the sea surface答案：B。细节理解题。由文章第二段特别是“these will keep the spar stable and prevent the turbine from moving up and down in the waves”可知B项正确。10To balance a bigger turbine high on a floating spar, a new type of turbine is to be designed with its gearbox sitting_.A. on the sea floor B. on the spar topC. at sea level D. behind the blades答案：C。细节理解题。由文章第三段最后一句“.one whose gearbox sits at sea level rather than behind the blades.”可知C项正确。11Wide applications of deepwater wind power technology can_.A. solve the technical problems of deepwater windmillsB. make financial profits by producing more turbinesC. settle the arguments about environmental problemsD. explore lowcarbon power resources available at sea答案：D。细节理解题。由文章最后一句“.it will open up vast areas of the planets surface to one of the best lowcarbon power sources available.”可知D项正确。
