19.Air pollution is a leading cause of cancer and classified among 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."Our task was to evaluate the air everyone breathes rather than focus on specific air pollutants,"the IARC'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 223,000 people worldwide,and there was also convincing evidence that it increases the risk of bladder (膀胱) cancer.Loomis said people in Asia,Eastern North America,some places in Central America and Mexico,as well as North Africa have relatively high exposure(暴露).Developing countries with large populations and booming manufacturing sectors,such as China,are particularly at risk.This week,Harbin,the capital city of Heilongjiang province,became the first Chinese city to officially suspendclasses due to serious smog,really good for teachers and students.
Many developed countries face similar problems,although to a lesser(较少的、次要的) degree than most developing nations.Between 91 and 96 percent of Europeans living in cities are exposed to levels of PM2.5-tiny particles with a diameter of less than 2.5 micrometers-that are higher than the WHO safety limits.
Although both the composition and levels of air pollution can vary dramatically from one location to the other,the IARC said its conclusions apply to all areas 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.
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.The underlined word"suspend"in Paragraph 2 probably meansC.
A.accelerate B.acknowledge C.delay D.decline
62.Why should the international community take action without further delay?A
A.A large number of people worldwide are exposed to air pollution.
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.The composition and levels of air pollution vary from place to place.
63.What might be the best title of the passage?D
A.PM2.5,bad effect.
B.Safety limits of air pollution.
C.Signals of air pollution.
D.Air pollution,cancer risk.

There are increasing fears of global warming.Consequently,many countries are focusing on the switch to a low carbon economy.This shift will lead to major changes in the supply and use of electricity.To meet these challenges,countries are investing in Smart Grid (智能电网) technology.This system aims to provide the electricity industry with a better understanding of power generation and demand to create a more efficient power network.
77.E
Smart Grid technology basically involves the application of a computer system to the electricity network.The computer system can be used to collect information about supply and demand and improve engineer's ability to manage the system.With better information about electricity demand,the network will be able to increase the amount of electricity delivered per unit generated,leading to potential reductions in fuel needs and carbon emissions (排放).
78.A
Smart Grid technology is profitable to consumers too.They will be able to collect real-time information on their energy use for each appliance.Varying tariffs (收费标准) throughout the day will give customers the motivation to use appliances at times when supply greatly exceeds (超过) demand,leading to great reductions in bills.
79.F
With these changes comes a range of things to be overcome.The first involves managing the supply and demand.Sources of renewable energy,such as wind,wave and solar,are unpredictable,and nuclear power,which is also set to increase as nations switch to alternative energy sources,is inflexible.A second problem is the fact that many renewable power generation sources are located in remote areas,such as windy uplands and coastal regions.
80.D
Although Smart Technology is still in its infancy,experimental plans to promote and test it are already underway.Consumers are currently testing the new smart meters which can be used in their homes to manage electricity use.Cities are investing money into smart energy,due to the high population density and high energy use.It is here where Smart Technology is likely to be promoted first,making use of a range of sustainable (可持续的) power sources,transport solutions.
Research is preliminary,but several studies(38)Cpeople who spend most of their days sitting are more likely to be fat,have a heart attack or even die.
