Global warming is the process of earth’s atmosphere heating up. Over the last 100 years, the average temperature of earth’s atmosphere has gone up 1 Fahrenheit. The weather has not changed exactly the same way in every area of the planet. But scientists think that the rise in average temperature is already affecting the earth’s climate.

Many scientists now believe that global warming is caused by cutting down trees, producing more trash, and polluting the environment which are some of the reasons why the temperature has gone up. Many scientists believe that the biggest causes of global warming are new human technologies that release greenhouse gases into the atmosphere.

The greenhouse effect is not new. Certain gases in the atmosphere, like carbon dioxide, nitrous oxide and methane, making it hard for heat energy to go into space. In the past, the climate didn’t change much because nature produced just the right amount of greenhouse gases to deal with it.

Today, most scientists are pretty sure that the rising temperature can’t be blamed on nature. Ever since the industrial revolution in the 1700s, humans have relied on machines for daily life. And many of those machines give off a lot of greenhouse gases. An increase in the release of greenhouse gases from human activities is throwing nature off balance.

The climate is a very complicated thing, but many scientists agree that the rising atmospheric temperature has already damaged the environment. Sheets of ice, called glaciers, are melting in Antarctica and other parts of the globe. As glaciers break off and melt into the oceans, they are adding warm water to the oceans and causing the sea level to rise.

Over the past 100 years, the sea level has risen 6-8 inches around the world. That means land along the coasts is beginning to disappear under water. Bigger and warmer oceans are also adding to other weather problems caused by pollution in the atmosphere. Some places have received more rain, others have had bigger storms and a few areas in the world have experienced unusual droughts.

1.What is mainly talked about in this passage?

   A. The melting of glaciers.                B. Global warming.

   C. The world’s weather.                     D. The earth’s temperature.

2.What causes global warming according to scientists?

   A. Human activities.                        B. The nature itself.

   C. The earth’s atmosphere.                  D. New discoveries

3.How can greenhouse gases make the globe warm?

   A. They keep heat in the atmosphere.            B. They let the heat go out into space.

   C. They release heat into the air.              D. They can make the other gases warm.

4.From the passage we can see that global warming will bring about _____.

   A. the pollution in the atmosphere              B. natural disasters

When it comes to hard, noisy traveling, we’ve found that sometimes we’d rather read about it than actually go. Here are some bestsellers for armchair travelers.

The Station by Robert Byron. In 1928, the 22-year-old man made a journey to Mount Athos, resulting in one of the best travel books ever written, matched only by Byron’s own, much more famous The Road to Osciana.

In Darkest Africa by Henry Monton Stanley. It’s about his great efforts to save an unlucky German doctor Eduard Schnitzer, who had no desire to be rescued at all.

A Traveler’s Alphabet: Partial Memoirs by Sir Steven Runciman. A to Z and around the world. He provides priceless information of long-gone princesses, priests, and places.

South: A Memoir of the Endurance Voyage by Sir Ernest Shackleton. As the planet started the global war, Shackleton and his brave group of explorers made an unsuccessful but heroic journey to cross Antarctica from 1914 to 1917.

The Michelin Red Guide: France 2005 Reading through this final listing of all the nice hotels and wonderful restaurants in France is better than going there, listening to Chirac talk about the poisonous American culture, and spending the price of this book for a tiny cup of tea and a cookie the size of your thumb.

The Past Is a Foreign Country by David Lowenthal. This great book of an armchair exploration tells us what has happened in the past and shows the relationship between us and the past travelers.

閱讀理解。
     Climate scientists hit back at disbelievers yesterday with a new study which brought about the evidence
for man-made global war ming was"stronger than ever".
     After analyzing more than 100 scientific papers published in the last few years, a team of British
researchers say there is an"in creasingly small possibility" that the world is warming up because of natural
variations (變動) in climate.
     Instead, man-made global warming-caused by the burning of fossil fuels-is making its mark on every
continent and ocean, they say.
     The studies used computer models to see whether changes in air temperature, sea ice, sea temperature,
wetness, rainfall and ocean saltiness recorded in the last 50 years could be explained by nature.
     Since 1980,the average global temperature has increased by around0.5℃,they found. The same warming
pattern was also found deep in the world's oceans.
     Natural forces such as volcanic eruptions and returning chan ges in the brightness of the sun could not
explain what was happen- ing to the world's climate, Dr Stott said.
     The sun's output had actually fallen over the last 50 years, he said.
     Even if the sun had got warmer over the last few decades-as some skeptics say-both the upper and lower
layers of the atmos phere should have got hotter.
     However, in the last 50 years the lower atmosphere has warmed while the upper atmosphere has actually
cooled, Dr Stott said.
     Drier parts of the world are getting drier, while wetter areas are getting more rain-a finding in agreement
with man-made climate change, the report found.
     And the amount of mid summer sea ice in the Arctic is also declining over time-even with the natural
yearly variations, the study found.
     The study comes along with growing public doubt about climate change.
1. With enough evidence the climate scientists prove _____.
A. global warming is disappearing recently
B. mankind isn't to blame for global warming
C. mankind is to blame for global warming
D. global warming will disappear sooner or later
2. What caused the global warming according to the British researchers?
A. Frequent volcanic eruptions across the world.
B. The increase of the brightness of the sun.
C. The warming pattern of the world's oceans.
D. The burning of fossil fuels by the human being.
3. The underlined word "skeptics" in Paragraph 8 refers these people who_____.
A. believe that mankind is to blame for global warming
B. believe global warming will disappear sooner or later
C. doubt the global warming will disappear sooner or later
D. doubt the global warming is caused by humankind
4. What can we infer from the last sentence of the passage?
A. The study has made the public live in a terrible dream at present.
B. Many people don't believe the study of the British researchers now.
C. The public have been used to the climate changes these years.
D. The result of the study comes from the opinions of the public.
