It is easy to miss amid the day-to-day headlines of global economic recession, but there is a less obvious kind of social upheaval（剧变）underway that is fast changing both the face of the planet and the way human beings live. That change is the rapid growth in urbanization. In 2008, for the first time in human history, more than half the world’s population was living in towns and cities. And as a recently published paper shows, the process of urbanization will only accelerate in the decades to come—with an enormous impact on biodiversity and potentially on climate change.

As Karen Seto, the lead author of the paper, points out, the wave of urbanization isn’t just about the migration of people into urban environments, but about the environments themselves becoming bigger to provide enough room for all those people. The rapid expansion of urban areas will have a huge impact on biodiversity hotspots and on carbon emissions in those urban areas.

Humans are the ultimate invasive species-when they move into new territory, they often displace the wildlife that was already living there. And as land is cleared for those new cities—especially in the dense tropical forests-carbon will be released into the atmosphere as well. It’s true that as people in developing nations move from the countryside to the city, the shift may reduce the pressure on land, which could in turn be good for the environment. This is especially so in desperately poor countries, where residents in the countryside slash and burn forests each growing season to clear space for farming. But the real difference is that in developing nations, the move from rural areas to cities often leads to an accompanying increase in income—and that increase leads to an increase in the consumption of food and energy, which in turn causes a rise in carbon emissions. Getting enough to eat and enjoying the safety and comfort of living fully on the grid is certainly a good thing-but it does carry an environmental price.

The urbanization wave can’t be stopped—and it shouldn’t be. But Seto’s paper does underscore the importance of managing that transition. If we do it the right way, we can reduce urbanization’s impacts on the environment “There’s an enormous opportunity here, and a lot of pressure and responsibility to think about how we urbanize,” says Seto. “One thing that's clear is that we can’t build cities he way we have over the last couple of hundred years. The scale of this transition won’t allow that.” We’re headed towards an urban planet no matter what, but whether it becomes heaven or hell is up to us.

E-waste is fast becoming a serious global problem. 1.

The source of e-waste

We live in a society that constantly produces and consumes electronic products. It is often cheaper to buy new pieces of equipment than to repair old ones. Also, through clever advertising, companies persuade consumers to replace their old TVs, mobile phones and computers for the latest models. E-waste is created when we throw away electronic equipment like this. In the EU alone, about 8.7 million tonnes of e-waste is produced each year. 2.

The problem with e-waste

Burying e-waste in landfills or burning it causes serious problems for the environment. 3. These substances can then leak into the ground in landfills or pollute the air when they are burnt.

Global recycling schemes (计划)

4. However, their schemes are not always managed properly and sometimes electronics are just sent to poor countries such as Ghana. Here they are often burnt in public areas, which is very bad for people’s health. Setting up recycling programs in the countries that create e-waste could solve this problem. E-cycling centres could recycle the parts that we can reuse and properly dispose of the rest.

Take-back policy

Another solution to e-waste is to make manufacturers responsible for their used products. This could mean forcing them to take back old products which are no longer wanted. 5.

Consuming less

We can all reduce the amount of waste we produce by buying electrical products only when we have to.

A.In recent years, many countries have started recycling e-waste.

B.They should then make sure they are properly recycled or reused.

C.Sadly, just over one million tonnes is recycled.

D.This report will examine this problem and provide some possible solutions.

E.By resisting the temptation to buy a product just to have the latest version, we cut down on e-waste.

F.Electronics contain dangerous chemicals and metals.

G.Both manufacturers and consumers must accept their responsibilities and make efforts to keep it to a minimum.

Libraries everywhere in the world have always been people’s only access to important sources of information.  This historical function of libraries has worked out for centuries and has made libraries a necessity to people.  Now, that function has been called into question by the fast development of digital media over the past several decades. In order to continue to hold the public interest, libraries everywhere are forced to develop means of granting access to these expensive new services to average people.

In the past, the publishing industry maintained the rights of libraries to freely provide published materials on the condition that libraries bought so many of their books. Since the new electronic publications can easily be copied in their completeness by the library readers, the publishing industry is reconsidering its former support of the library system. There have even been attempts to stop libraries from delivering digital media.

In addition to the reluctant cooperation of the publishing industry, there is the problem that the newer forms of information are much more specialized than those which they replace. Deciding how to transfer already limited resources is increasingly difficult as there are more methods. While a single reference index(索引) might have covered an entire field in the past, now there are frequently several specialized indexes available in electronic form. Above all, in order to continue to make use of the newer technology, libraries must decide which kinds of material are most useful to the majority of their readers. There are many different solutions being applied, but only the process of trial and error will help find out the most effective method.

（Note: Answer the questions or complete the statements in NO MORE THAN 20 WORDS）

1. What has been called into question?

2. In the past, publishers cooperate with libraries because ______________.

3. The most important way to use the new technology is to determine ________

4. According to the passage, how can best solutions be found?

The way we cook is important. In many countries, the two sources of heat used for cooking are natural gas or electric stoves. The World Health Organization(WHO) warns that millions of people are dying every year from indoor air pollution. The WHO finds that poor cooking, heating and lighting technologies are killing millions of people each year.

Indoor air pollution results from the use of dangerous fuels and cook stoves in the home. WHO officials say nearly three billion people are unable to use clean fuels and technologies for cooking, heating and lighting. And they say more than seven million people die from exposure to indoor or outdoor air pollution each year. Of that number, the WHO says about 4.3 million people die from household air pollution given off　 by simple biomass(生物燃料）and coal stoves.

These findings show that the home use of poisonous fuels is to blame for many of these deaths. These fuels include wood, coal, animal waste and so on. Carlos Dora is Coordinator in the WHO’ s Department of Public Health, Environmental and Social Determinants of Health. He says people should not use unprocessed coal and kerosene(煤油）fuel indoors. He says opening a window or door to let out the harmful air will not correct the situation. It will only pollute the outdoors. “New technologies and clean fuels can rid people of this problem.”

The United Nations found that more than 95 percent of families in sub-Saharan Africa depend on solid fuels for cooking. It says huge populations in India, China and Latin American countries, such as Guatemala and Peru, are also at risk.

Nigel Bruce is a professor of Public Health at the University of Liverpool. He says researchers are developing good stoves and other equipment to burn fuels in a more efficient way.“There are already many technologies for clean fuels available now. An effective and reasonably low-cost ethanol(酒精）stove that is made by Dometic (a Sweden-based company)is now being tested out. Another interesting development is electric induction stoves.” In India, you can buy an induction stove for about $8. And in Africa you can buy a solar lamp for less than $1.

1.How is Paragraph 2 mainly developed?

A. By making classifications.　　 B. By listing numbers.

C. By following time order.　　　　 D. By describing a process.

2.According to Carlos Dora, what is the best solution to indoor air pollution?

A. People should use an effective air cleaner.

B. People should use new technologies and clean fuels.

C. People should open a window or door to let out the harmful air.

D. People should prevent themselves from being exposed to harmful air..

3.What can we learn from the passage?

A. Most of the deaths from indoor pollution are in developing countries.

B. Burning solid fuels can help limit indoor air pollution .

C. People can buy ethanol stoves made by Dometic in India.

D. There are already two technologies for clean fuels available for use.

4.Which would be the best title for the passage?

A. The way we cook is changing.

B. Cause of indoor air pollution.

C. The development of electric stoves.

D. Indoor air pollution kills millions each year.
