At the onset of a northern winter, many dream of warmer climates.In 1934 the Canadian-born composer Colin Mcphee did more than dream. He set out for the island of Bali.

In his book A House in Bali,Colin Mcphee described how he first gained insight into the essence of Balinese music.For about a month he had been working on transcribing a complete score to a Balinese play he had seen. It seemed impossible that so much beauty could be achieved with a scale(音阶)of only five tones.

But the distinctive embellishments(修饰音)of the music eluded him.Fortunately a young household helper and his friend decided to assist. One morning they set two objects next to Mcphee’s piano.They were gangas--metal keyed instruments.The two boys played them in what struck Mcphee as”a fast duet(二重奏） in Morse code”.

At last the composer had found the key to Balinese music.“Wait!” Mcphee would call out from the piano as the boys flew along,“Stop!Please!That bit once more!”

Patiently the boys would stop and began again.But soon they were flying again,faster than ever, amazing Mcphee with their memory and precision. Sometimes the patterns repeated.Sometimes they opened up into something new. Then, suddenly the whole duet would fly apart and the boys would burst out laughing,breaking the spell.

Although Colin Mcphee left the island in 1939,he remained spellbound by Balinese music.And its rich,distinctive sound would colour many of the compositions he would write for the next quarter century.

Around 200 million years ago, the earth was 18 degrees warmer than it is now.　 That might be a bit hot for humans, but it was just right for the giant dinosaurs that wandered about the earth during the Mesozoic (中生代的) era. A new study found that planteating dinosaurs may have contributed to the warming of the earth­by releasing significant amounts of methane (甲烷)．

The study, published in science journal Current Biology, focused on sauropods, long­necked herbivores (食草动物) that munched (用力咀嚼) on the top of trees. They　 were the largest of the dinosaurs; food broke down in their　 stomachs for long periods of time.　 The researchers estimate that a sauropoda released 2,675 liters of methane per　 day—adding up to a large amount of the greenhouse gas　 being pumped from dinosaur's gut into the atmosphere.

Plant eaters naturally release methane as part of their　　 digestive process. The larger the animal, the more methane　 it produces. Methane, a greenhouse gas, traps heat and remains in the atmosphere for approximately 9­15 years,　 which warms the atmosphere.

Today,　 some　 animals,　 such　 as　 cattle,　 goats　 and　 sheep, produce large amounts of methane as a by­product　 to their food digestion. Methane is also released from human—influenced sources such as landfill, agricultural activities, coal mining and other industrial practices—which all contribute to today's climate change, according to the　 Environmental Protection Agency.

The researchers estimate that earth's sauropods would　 have produced about 520 million tons of methane per　 year—similar to the total amount of methane produced today by natural and man­made sources.　 However, the researchers warn that their numbers are estimates based on　 multiple assumptions about the digestive systems and populations of dinosaurs.

The author of the study David Wilkinson says the　 emission of methane from dinosaurs would have been just　 one of the causes of warm climate during the Mesozoic era.　 Other　 causes　 include　 gases　 produced　 from　 volcanoes,　 swamps, shallow seas and so on. Still, Wilkinson says，“　 The amount of methane from dinosaurs is large enough to　 have a measurable effect.”

1.Scientists think dinosaurs may have led to the global　　　 warming because ________.

A．they ate everything they found

B．they usually had a good appetite

C．they released a lot of methane

D. there were too many dinosaurs on earth

2.What do we know about dinosaurs from Paragraph 2?

A．Sauropods fed on plants.

B．Sauropods were of medium size.

C．Dinosaurs used to live on trees.

D．Dinosaurs digested food quickly.

3.Which　 of　 the　 following　 activities　 doesn't　 produce　　　 methane?

A．Coal is dug out by machine.

B．Trees and flowers are planted.

C．Goats digest grass under the tree.

D．Food is being processed in the factory.

4.How does the author make his writing reliable?

A．By listing some facts.

B．By making predictions.

C．By citing figures.

D．By using mind pictures.

5.David Wilkinson seems to believe that ________.

A．methane had little effects on the earth

B．many other factors contributed to warm climate

C．other causes for warm climate were worth considering

D．dinosaurs were mainly to blame for global warming

Against the supposition than 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 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 next several centuries as 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 far­off 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 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 predicated, 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.

1.According to the new findings, taking steps to prevent northern forest fires may ________.

A．result in a warming climate

B．cause the forest fires to occur more frequently

C．lead to a longer fire season

D．protect the forests and the environment there

2.The following are all the immediate effects after a forest fire EXCEPT________.

A．large amounts of greenhouse gases enter the atmosphere

B．the levels of ozone which is a type of oxygen increase

C．snow on the ground mirrors more sunlight back into space

D．ashes from the fire fall on the ice surface and take in more radiation from the sun

3.Earlier studies about northern forest fires ________.

A．analyze all aspects of how northern fires influence climate

B．indicate that forest fires will pollute the atmosphere

C．suggest that people should take measures to protect environment

D．suggest that the fires will speed up climate warming

4.The underlined phrase “soak up” in the last paragraph most probably means ________.

A．released　 B．absorbed　 C. created　 D．distributed

Climate change has already begun to impact our planet in more ways than we can think.

1. Saving the environment starts with us and it is our responsibility to act against these terrible changes to preserve the planet for future generations.

Make your commute green. Millions of people drive to work every day. 2. However, the downside to this is that millions of cars emit greenhouse gases that destroy our atmosphere. There are always other options that you can utilize to make your commute to work eco-friendly. For starters, taking public transportation to work is a great way to cut out emissions. Riding your bike to work is also incredibly helpful to the environment and is a great method to get exercise.

Be more conservative with energy usage. Becoming more energy efficient is a great way to prevent pollution. 3. Make sure to turn off lights and unplug devices that you are not using anymore when you are done with them. Replace your light bulbs with energy-efficient light bulbs to help you save electricity too.

Recycle. Manufacturing plants emit a large number of greenhouse gasses per year. It is unavoidable in the production of goods that we use on a regular basis. However, a cleaner alternative would be to invest in recycling. 4. The professionals will take these items to a processing plant where they will be remade into other recyclable materials again.

5. Focusing your efforts to spread awareness about renewable energy is the best way to create a positive impact in your community. By informing others about how renewable energy is better than fossil fuels (化石燃料), you will persuade others into investing in the idea.

A.Educate yourself and others.

B.Encourage the use of renewable energies.

C.It’s simply unavoidable in our modern-day society.

D.Be sure to collect your abandoned paper, plastic and electronics.

E.Fortunately, there are always things we can do to fight against it.

F.This requires you to cut down on energy usage in your household.

G.Recycling is a cost-effective and eco-friendly process that eliminates waste.
