A
Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone（臭氧） levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.

Several animal species including gorillas in Rwanda and tigers in Bangladesh could risk extinction if the impact of climate change and extreme weather on their habitats is not addressed, a UN report showed on Sunday.
Launched on the sidelines of global climate negotiations in Durban, the report by the United Nations Food and Agriculture Organization shows how higher temperatures, the rise in sea levels, deforestation and excessive land use have damaged the habitats of certain species, especially in Africa.
“Many ecosystems have already been stressed by increasing population, historical and recent deforestation, unsustainable management practices and even invasive (入侵的) species,” Eduardo Rojas-Briales, assistant director general at the FAO's forestry department, said at the launch of the report.
The most affected areas include mountains, isolated islands and coastal areas, which limit the possibilities for animals to migrate elsewhere and create new habitats.
“The remaining populations become surrounded in very small ecosystems, they have inbreeding (近亲交配) problems ... and at the end these species may disappear,” he added.
Other examples of affected animals included elephants in Mali, lions in the Serengeti and crocodiles in Malawi.
The report said an estimated 20-30 percent of plant and animal species will be at higher risk of extinction due to global warming and a significant proportion of native species may become extinct by 2050 as a consequence.
Other consequences could include the spread of invasive species and infectious diseases, it said.
The report urges more focus on restoration of damaged ecosystems, especially those key to dealing with climate change such as mangroves(红树林), inland waters, forests, savannahs(非洲大草原) and grasslands.
The FAO also called for the creation of migration corridors for animals in areas where their movement was limited.
The organization said while more resources were flowing to biodiversity conservation, more action at the government and policy level was needed.
It also urged local communities to develop projects that mitigate the impact of climate change on wildlife, naming eco-tourism activities as an example.

There are some special traditions in Hawaii .People are very friendly and always welcome visitors. They give visitors a lei,a long necklace made of beautiful fresh flowers. Men wear bright flowered shirts and women often wear long flowered dresses. There are traditional Chinese ,Japanese and Fillipino holidays and all the holidays from the United States. They call Hawaii the Aloha State. Aloha means both hello and good-bye. It also means “I love you”.

Usually when people from different countries,races and traditions live together,there are serious problems. There are a few problems in Hawaii ,but,in general,people have learned to live together in peace.
Hawaiians get most of their money from travelers,and most of the travelers come from the mainland and from Japan. There are so many peole living in Hawaii now that there are residential（居住的） areas where there used to be farms. Some of the big sugar and apple companies have moved to the Philippines,where they don't have to pay workers as much money. The families of the first people who came from the US mainland own the important banks and companies. Japanese are also buying or starting business.
【小题1】What might be the best title for this text?

A．Hawaii ,the Aloha StateB．Living Hard Together
C．The Flower of HawaiiD．The Problems of Hawaii

Getting close to active or erupting volcanoes can be dangerous. But for Michael Rampino, it’s all in a day’s work. Rampino is a volcanologist, a scientist who studies volcanoes and how they affect our planet. Rampino has been close to red-hot lava flows (熔岩流) in Hawaii and explosive volcanoes in Indonesia. He knows when to get close to an active volcano and when to back away.

Rampino wasn’t always a volcanologist. He worked for NASA for seven years. He studied rocks until he began to research climate change and the effects that volcanoes have on climate. He became interested in the subject. “Once I started working with volcanoes,” Rampino said, “I was hooked.”

Rampino is a professor at New York University. As part of his job, he travels to areas where volcanoes have been active. “Active” means they have erupted within the past few centuries and probably will erupt again. Rampino studies the deposits (沉积物) of ash and other materials from the eruptions. The ash may hold clues to what happened to the Earth in the distant past. It may also help scientists predict what could happen to Earth’s climate in the future.

Rampino doesn’t work alone. He works with a team of scientists who use computers to stimulate (模拟) the effects volcanoes have on Earth’s atmosphere.

Being a volcanologist may be hard work, but it’s also fun. “It’s cool traveling the world studying “to understand the events that have shaped Earth’s history.”

1.To Rampino, being close to active volcanoes is _____.

A．scary but necessary                     B．adventurous but meaningful

C．impossible and unnecessary               D．dangerous but urgent

2.The underlined word “hooked” in Paragraph 2 probably means “_____”.

A．trapped           B．touched           C．attracted          D．frightened

3.Rampino’s study on volcanoes might help _____.

A．warn people to protect the environment

B．support the study of Earth’s future climate

C．tell the future eruption time of the volcanoes

D．reduce the possibility of the volcanoes’ eruptions

4.In which part of a newspaper could we find this text?

A．People.           B．History.           C．Climate.           D．Business.

 

Seth DeBolt is a plant scientist at the University of Kentucky US. He and other scientists wanted to find a source of fuel that poor people in rural areas of developing countries could use to make electricity.

The United Nations Development Program says a billion and a half people have no electricity. A billion others have an undependable supply.

    Professor DeBolt went on a study trip to rural Indonesia. He saw that there was very little waste in the use of agricultural products. Everything that farmers grew was used for something. Even the remains of fruit that people did not eat were fed to chickens.

Little waste meant there was little that could be used for fuel. Growing a separate fuel crop would take land away from food crops. That was something Professor DeBolt did not want to do.

    DeBOLT said, "The people at most risk with respect to energy poverty, typically they're the same people who have food insecurity issues as it is. And then any change in availability would be most damaging to that group of people."

    But he found one item that was in plentiful supply and would not create competition between food and fuel. Coconut shells are generally thrown out. Yet Professor DeBolt says it has an "excellent" heating value. All someone needs is a way to release that energy.

    DeBolt says he and his team see possibilities for coconut power. "Coconuts are growing here and these are the areas where there is possibility for energy poverty to be eased at least in part by these small-scale production systems."

    The researchers say these systems could provide as much as thirteen percent of the energy needs of a country like Indonesia. Other tropical countries with large crops of coconuts and similar fruit could benefit, as well.

    But DeBolt says this is not a perfect solution. There are technical questions, like how to safely deal with the dangerous waste produced in the process. And there needs to be money to get these projects started.

1.Professor DeBolt went on a study trip to rural areas of developing countries to       .

    A. help farmers make full use of waste

    B. seek certain materials to make electricity

    C. persuade farmers to grow more coconuts

    D. find a suitable place to carry out the experiment

2.DeBolt thought it was not a good idea to grow fuel crops because       .

    A. there are plenty of coconuts

    B. local farmers have no interest in it

    C. it would make food problems worse

    D. fuel crop has little use for local farmers

3.The last two paragraphs mainly tell us that coconut power       .

    A. needs further experiments and efforts

    B. can help solve energy problem perfectly

    C. will cause technique and money problems

    D. has drawn Indonesia's government attention

4.What might be the best title for the passage?

    A. Make Full Use Of Coconuts            B. Make Power From Coconuts

C. A Perfect Solution                            D. Food And Energy Problems
