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 are some of the reasons that 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, prevent heat energy from escaping back 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 last 100years, 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.

68. 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.

69. What causes global warming according to scientists?

   A. Human activities.                     B. The nature itself.

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

70. 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.

71. From the passage we can see that global warming will bring about _________.

   A. the pollution in the atmosphere            B. natural disasters

   C. population pollution                     D. the rise of glaciers

You don’t have to ask Barack Obama what it is like to be a president-elect. Chances are you can be one, too, and it won’t take more than 30 years’ efforts to achieve that.

A new computer game, Commander in Chief, offers the chance to step into the president’s shoes and see whether you can do a better job running the country than he can.

The video game will be available on January 20, the day Obama is sworn in (宣誓就职) as president.

So what will you do in the game?

Like Obama, your early task is to select members of the Cabinet(内阁)from 250 personality types. Then you immediately face internal(国内的)and external challenges. Every decision you make has an in-game consequence.

“You can put your own political theories into action and see the domestic(国内的)and international effect,” said the lead designer Louis-Marie Rocques.

Internal decisions involve managing budgets, security, education, health care and discussion over many proposed laws. You also have to respond to critics. Every decision has a consequence, which changes the political environment. For example, raising taxes will raise criticisms and protests while lowering taxes means you will have less money to play with.

What about external decisions? Well, you have to deal with military issues, global economics, trade agreements, and spending time lobbying(游说)other presidents. You can determine the course of world events by invading(侵略)a neutral country, or toppling(推翻)an unfriendly country but then you must face the economic, political, and military consequences.

Don’t want to be president of the US? The game also lets you become virtual(虚拟的)leader of other countries including France, Germany, Spain and Russia.

The purpose of writing this passage is mainly to     .

   A. show you how hard it is to be the newly-elected president, Barack Obama

   B. explain why the video game is so popular among American citizens

   C. introduce to you one special computer game, Commander in Chief

   D. inform how designers developed the interesting computer game

Which of the following items belongs to internal affairs in the game?

A. Managing budgets, responding to critics and military issues.

   B. Managing budgets, raising taxes and trade agreements.

   C. Health care, discussing proposed laws and lowering taxes.w(w w.ks&5 u.c*o m

   D. Education, security and lobbying other countries.

Which of the following is TRUE according to the passage?

   A. Those who want to be a president one day will get a taste of their private life.

   B. The first task in the game is to form the Cabinet consisting of 250 members.

   C. The video game has hit the stores in America and enjoys sales success.

   D. Like a real president, the players will face challenges at home and abroad

Health and climate scientists have mapped how climate change affects different parts of the world in different ways. The scientists point to the fact that changes in the past thirty years may, have been affecting human health. Possible effects include more deaths from extreme(极度的) heat or cold, more storms and more crop failures in dry periods.

The health and climate scientists recently estimated(估计) that climate changes caused by human activity lead to more than one hundred and fifty thousand deaths each year. Cases of sickness are estimated at five million. And the W.H.O. says the numbers could rise quickly by the year of 2003.

Jonathan Patz of an environmental institute led the study. Professor Patz points out that climate scientists connected global warming with the heat that killed thousands in Europe in August, 2003. But he says poor countries least responsible(对……负责) for the warming are most in danger from the health effects of higher temperatures.

Professor Patz says areas in greatest danger include southern and eastern Africa and coastlines along the Pacific and Indian oceans. Also, large cities experience what scientists call a "heat island"effect that can make conditions worse.

Representatives(代表) from about two hundred countries hold a meeting in Canada, to discuss climate change. The ten-day meeting ends on December 9th. It is the first such United Nations meeting since the Kyoto Protocol(京都议定书) took effect earlier this year. The agreement aims to reduce the amount of carbon dioxide(二氧化碳) and other heat-trapping(吸热的) gases sent off into the air.

1.Who is Jonathan Patz?

A.A scientist responsible for the climate change.

B.A scientist in charge of the study of the climate change.

C.A professor interested in the climate change.

D.A professor who is a representative from an African country.

A.Climate changes affect different parts of the world in the same way.

B.The ten-day meeting is the first United Nations meeting on climate change.

Texas——US President George W.Bush and Russian President Vladimir Putin failed to bridge their differences over a key arms control treaty last week, but that didn’t stop them from backslapping(喧闹的狂欢) as they ended a summit.

The two leaders also offered differing interpretations of the fate of nuclear warheads to be removed from missiles under arms reductions they each announced last week.Bush said he intended to destroy the warheads, but Putin said their fate should be negotiated.
