A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below l6℃．Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate．Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world．

    In the past hundred years，humans have begun destroying rainforests in search of three major resources(资源): land for crops，wood for paper and other products，land for raising farm animals．This action affects the environment as a whole．For example，a lot of carbon dioxide(二氧化碳) in the air comes from burning the rainforests．People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

    There are two main reasons for this．Firstly，when people cut down trees，generally they can only use the land for a year or two．Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world’s wood supply．

    Rainforests are often called the world’s drug store．More than 25％ of the medicines we use today come from plants in rainforests．However，fewer than l％of rainforest plants have been examined for their medical value．It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests．

Rainforests can help to adjust the climate because they                ．

  A．reflect more heat into the atmosphere

  B．bring about high rainfall throughout the world

  C．rarely cause the temperature to drop lower than l6℃

  D．reduce the effect of heat from the sun on the earth

What does the word “this” underlined in the third paragraph refer to? 

  A．We will lose much more than we can gain．

  B．Humans have begun destroying rainforests．

  C．People have a strong desire for resources．

  D．Much carbon dioxide comes from burning rainforests．

It can be inferred from the text that      . 

  A．we can get enough resources without rainforests

  B．there is great medicine potential in rainforests

  C．we will grow fewer kinds of crops in the gained land

  D．the level of annual rainfall affects wind patterns

What might be the best title for the text? 

   A．How to Save Rainforests                B．How to Protect Nature

   C．Rainforests and the Environment        D．Rainforests and Medical Development

Cutting meat production and consumption by 30 percent would help to reduce carbon emissions(排放) and improve health in the most meat-loving nations, scientists said on Wednesday.

Using prediction models, British and Australian researchers   1   that improving efficiency, increasing carbon capture and  2   fossil fuel dependence in farming would not be enough to   3    emissions targets.

But combining these steps  4   a 30 percent reduction in livestock（家畜）  5   in major meat-producing nations and a similar  6   in meat-eating, would lead to "substantial population health benefits" and cut emissions, they said.

The study found that in Britain, a 30 percent  7  intake of animal-source saturated（饱和的） fat by adults would reduce the  8   of premature（过早的） deaths from heart disease by some 17 percent -- equivalent to 18,000 premature deaths reduced in one year.

In Sao Paulo, Brazil, it could mean as  9   as 1,000 premature deaths reduced in a year, they said.

  10   the United Nations Food and Agricultural Organization, 18 percent of all greenhouse gas emissions are from meat production and experts say rising  11   for meat, particularly in countries with growing economies, could  12   livestock production up by 85 percent from 2000 levels  13   2030.

The scientists said global action was needed to maximize the benefits of cutting meat production and  14 , and that the environmental  15   "may apply only in those countries that currently have high production levels."

The study was  16   in The Lancet medical journal as part of a series in climate change and health  17   the Copenhagen global climate summit scheduled next month.

In a second study, British scientists found that increased walking and cycling, and  18   cars, would have a much greater impact on health  19   low-emission vehicles in rich and middle-income countries.

Andrew Haines, director of the London School of Hygiene and Tropical Medicine and head of the research series, said delegates at Copenhagen needed "to understand the potential  20   impacts of their plans."

A new factory that turns used wine bottles into green sand could revolutionize the recycling industry and help to filter（过滤）the nation's drinking water.

For the last 100 years special high grade white sand quarried（开采）at Leighton Buzzard in Bedfordshire has been used to filter tap water to remove bacteria and impurities—but this may no longer be necessary.

The green sand has already been successfully tested by water companies and is being used in 50 swimming pools in Scotland to keep the water clean.

Backed by one million pounds from the European Union and the Department for Environment, Food and Rural Affairs(Defar),a company based in Scotland is building a factory to turn beverage bottles back into the sand from which they were made.

The idea is not only to avoid using up increasingly scarce sand in Scotland and avoid any further quarrying but also to solve a crisis in the recycles only 750 000 tones of it.

Howard Dryden, the scientist and managing director of the company has spent six years working on what he calls Active Filtration Meadia, or AFM, the recycled glass. He says he needs bottles that have already contained drinkable liquids to be sure that drinking water would not be polluted.

"The fact is that tests show that AFM does the job better than glass, it is easier to clean and reuse and has all sorts of properties that make it ideal for other applications, "he claimed. He also thinks the market will be able to take 250 000 tones of green sand a year. The plan is to build five or six factories in cites in UK where the bottles come from to cut down on transport.

The factory will be completed this month and is expected to go into full production on January 14 next year. Once it is providing a "regular" product, the government's drinking water inspectorate will be asked to perform tests and approve it for general use by water companies.

It may no longer be necessary to use high-grade white sand to keep water clean because_____.

there is no need to keep water clean

A new factory has been set up

The green sand has been used to keep the water clean

White sand is being use up

According to the passage ,the new idea can do the following except_____.

A. avoiding using up increasingly scarce sand

B. avoiding further quarrying of white sand

C. solving the crisis in the recycling industry

D. cutting down the cost on transport

Tests show that ______ in keeping the water clean.

A .AFM is more efficient than white sand

B.AFM is more efficient than glass

C. glass is more efficient than AFM

D. white sand is more efficient than green sand

The underlined word "Backed" in the third paragraph can best be replaced by"_____".

A. Allowed             B. Opposed

C. Supported            D. Forbidden

What would be the best title for the passage?

A. Revolution in the Recycling for the Industry.

B. Modern Technology an New Markets.

C. Revolution in Environmental Protection.

D. Unlocking the Benefits of Green Sand.
