According to the UN Intergovernmental Panel (专家咨询组) on Climate Change, global temperatures have risen by approximately 0.6℃ in the past century, caused mainly by emissions of greenhouse gases produced by human activities，such as　 the　 burning　 of　 fossil　 fuels　 and　 deforestation.Temperatures are to increase between 1.6℃ and 5.8℃ in the next century, accompanied by sea level rise and an increase in the frequency of extreme weather events.

The best available evidence suggests that climate changes since the 1970s may already be causing over 150,000 deaths annually, and that greenhouse gas emissions would increase disease burdens　 in　 the　 coming　 decades.The　 risks　 are concentrated in the poorest population, who have contributed least to the problem.

The Kyoto Protocol (京都议定书) is signed by 128 nations，and commits the participating industrialized countries to cutting emissions of greenhouse gases by over 5% below 1990 level by the period of 2008­2012.

“Over 600 thousand people died in weather­related disasters in the 1990s.Temperature and rainfall influence the rates of diseases and infections including malaria，and malnutrition，which together cause over 3.5 million deaths a year.The Kyoto Protocol is the first step towards protecting the climate system，which exerts such a strong influence on our health”，said Dr Kerstin Leitner，Assistant Director­General for Sustainable Development and Healthy Environments.

While acting to reduce greenhouse gas emissions, it is also essential to protect vulnerable (脆弱的) communities from the effects of climate changes.WHO works to promote measures such as protection from malaria and other climate sensitive diseases, and reliable access to clean water and sanitation, for people　 in the　 most vulnerable developing countries.Increasing disease control efforts will also help to protect current and future generations from the impacts of greenhouse gas emissions.

1.According to the passage, what is the reason for the rise of global temperatures?

A．The burning of fossil fuels.

B．The rise of sea level.

C．Extreme weather disasters.

D．The emissions of greenhouse gases.

2.Which of the following is true?

A．Weather­related disasters caused over 3.5 million deaths.

B．The climate system has a deep impact on human health.

C．The members of the Kyoto Protocol are all industrialized countries.

D．The poorest population are to blame because they contribute least to the problem.

3.In order to protect communities, WHO takes some measures except________.

A．preventing diseases caused by climate changes

B．helping to provide clean water

C．aiding to offer sanitation

D．gaining access to vulnerable developing countries

4.What does the passage mainly talk about?

A．Climate changes and the effects on human health.

B．Climate changes cause over 15,000 deaths annually.

C．Who promotes measures such as protection from malaria.

D．The Kyoto Protocol helps to protect human health.

Global warming is when the earth heats up，the temperature rises.It happens when greenhouse gases—carbon dioxide，water vapor，nitrous oxide(二氧化氮)，and methane(沼气) trap heat and light from the sun in the earth’s atmosphere，which increases the temperature.This is like when heat is trapped in a car.On a very hot day，the car gets hotter when it is out in the parking lot.This is because the heat and light from the sun can get into the car，by going through the windows，but it can’t get back out.Once the light is inside the car，it is trapped and the heat builds up，just like it does in the earth’s atmosphere.This is what the greenhouse effect does to the earth.The heat and light can get through the atmosphere，but it can’t get out.As a result，the temperature rises.

Sometimes the temperature can change in a way that helps us.The greenhouse effect makes the earth appropriate for people to live on.Without it，the earth would be freezing，or on the other hand it would be burning hot.We would not get the sun’s heat and light to make the night somewhat warm.During the day，especially during the summer，it would be burning because the sun would be up with no atmosphere to filter(过滤) it，so people，plants，and animals would be exposed to all the light and heat.

Although the greenhouse effect makes the earth able to have people living on it，if there gets to be too many gases，the earth can get unusually warmer，and many plants，animals，and people will die.They would die because there would be less food (plants like corn，wheat，and other vegetables and fruits)．This would happen because the plants would not be able to take in the heat.This would cause us to have less food to eat，but it would also limit the food that animals have.Gradually，people，plants，and animals would all die of hunger.

People are doing many things to try to stop global warming.One thing people are doing is carpooling.Carpooling is driving with someone to a place that you are both going to.This minimizes the amount of greenhouse gases put into the air by a car.

Another thing that people are doing is being more careful about leaving things turned on like the television，computer，and the lights.A lot of people are taking time away from the television，and instead，they are spending more time outdoors.This helps our planet out a lot.Now，more people are even riding buses，walking to school，and riding their bikes to lower the amount of greenhouse gases in the air.

Planting trees and recycling also help.If you recycle，less trash goes to the dump，and less trash gets burned.As a result，there are fewer greenhouse gases in our atmosphere.Although adults do many things to help stop global warming，kids can do just as much.

1.By the example given in Paragraph 1，the author wants to ________.

A．explain how greenhouse gases work

B．show his feeling in a car in hot summer

C．tell us cars are causes of greenhouse gases

D．say that there are greenhouse gases in every car

2.The underlined word “it” in Paragraph 2 refers to “________”．

A．light　                                 B．heat

C．temperature　                             D．greenhouse effect

3.What is the main idea of Paragraph 3?

A．If there is greenhouse effect，all the plants will die.

B．Human beings are likely to disappear from the earth.

C．Crops can’t take the heat if there is greenhouse effect.

D．Although greenhouse effect is necessary，too much of it causes us to die.

4.What will the author most probably discuss in the paragraph that follows?

A．Why cars and buses pollute the air a lot.

B．What kids can do to help stop global warming.

C．What global warming is doing to the environment.

D．Who should be responsible for the environmental problems.

You might think that “global warming” means nothing more than a rise in the world’s temperature But rising sea levels caused by it have resulted in the first evacuation（撤离）of an island nation—the citizens of Tuvalu will have to leave their homeland.

During the 20th century, sea level rose 8—12 inches. As a result .Tuvalu has experienced lowland flooding of salt water which has polluted the country’s drinking water.

Paani Laupepa , a Tuvaluan government official ,reported to the Earth Policy Institute that the nation suffered an unusually high number of fierce storms in the past ten years .Many scientists connect higher surface water temperatures resulting from global warming to greater and more damaging storms.

Laupepa expressed dissatisfaction with the United States for refusing to sign the Kyoto Protocol, an international agreement calling for industrialized nations to reduce their greenhouse gas emissions（导致温室效应的气体排放）,which are a main cause of global warming . “By refusing to sign the agreement, the US has effectively taken away the freedom of future generations of Tuvaluans to live where their forefathers have lived for thousands of years,” Laupepa told the BBC.

Tuvalu has asked Australia and New Zealand to allow the gradual move of its people to both countries .

Tuvalu is not the only country that is vulnerable （易受影响的）to rising sea levels .Maumoon Gayoon ,president of the Maldives ,told the United Nations that global warming has made his country of 311,000 an “endangered nation”.

1.The text is mainly about ________.

A．rapid changes in earth’s temperature

B．bad effects of global warming

C．moving of a country to a new place

D．reasons for lowland flooding

2.According to scientists, the DIRECT cause of more and fiercer storms is ________.

A．greenhouse gas emissions in industrialized nations

B．higher surface water temperatures of the sea

C．continuous global warming

D．rising sea levels

3.Laupepa was not satisfied with the United States because it did not ________.

A．agree to reduce its greenhouse gas emissions

B．sign an agreement with Tuvalu

C．allow Tuvaluans to move to the US

D．believe the problems facing Tuvalu were real

4.The country whose situation is similar to that of Tuvalu is ________.

A．Australia          B．New Zealand    C．the Maldives   D．the United States

Climate change, global warming, the greenhouse effect … these days nobody denies that there is something strange and worrying happening to the atmosphere. Scientists are puzzled by the rise in carbon dioxide in the atmosphere. They are afraid that the world may be a short way from what they refer to as uncontrolled global warming.

At Mauna Loa Observatory in Hawaii, meteorologists(气象专家) have been carefully monitoring the amount of carbon dioxide in the Earth’s atmosphere for the past 50 years. Until recently, there has been a gradual increase of around 1.5 parts per million (ppm). In 2013 the figure rose to 2.08 ppm and in the following year they registered an increase of 2.54 ppm.

.Climate analysts feel that it istoo soon to draw conclusions about the phenomenon although the public are concerned that the carbon dioxide emissions are getting out of control. Jason Samenow, the chief meteorologist in the American National Weather Service,thinks that instead of having decades to find a solution to the problem, people might have only a few years. He believes that the Earth’s natural systems for absorbing the gas are breaking down resulting in the uncontrolled green house effect. He insists that this is something that could happen if the Earth’stemperatures rose to such a degree that it was unable to contain the heat. .

One interesting aspect of this climate change ng down resulting in the uncontrolled greenhouse effect. He insists that this is something that could happen if the Earth’s temperatures rose to such a degree that it was unable to contain the heat.is that it is not happening in a uniform way around the world. Carbon dioxide levels in the South Pole are noticeably lower. This suggests that something has happened in the northern hemisphere that set off the rise. Forest fires in North America might hold the answer to the puzzle, along with very hot summers in Europe.

The 2014 heat wave was certainly out of the ordinary. Statistics claim that more than 30,000 people lost their lives as a direct result of the high temperatures. Scientists are being cautious in their interpretations. Most feel that it is too soon to say that a new trend has been set. All agree that the phenomenon needs to be closely observed.

1.What puzzles scientists according to Paragraph 1?

A. Something strange and worrying in life.

B. Uncontrolled global warming.

C. The increase in carbon dioxide in the atmosphere.

D. The effects of climate change on everybody.

2.What opinion does Jason Samenow hold on the gradual increase of carbon dioxide?

A. People still have decades to solve this problem.

B. Uncontrolled greenhouse effect may happen in some situation.

C. The Earth’s natural systems for absorbing the gas have completely broken down.

D. The public shouldn’t be responsible for carbon dioxide emissions.

3.What does Paragraph 4 mainly talk about?

A. Forest fires in North America.

B. Low temperatures in the South Pole.

C. Hot summers in Europe.

D. North and South differences in climate change.

4.How will scientists deal with the high temperatures?

A. By observing the phenomenon closely.

B. By giving a solution directly.

C. By experiencing high temperatures personally.

D. By setting a new trend soon.

高三英语单项填空中等难度题查看答案及解析

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO₂ is also affecting the ocean chemistry and potentially harming sea life.

Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades.

"We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is CO₂ levels. And we've been able to record this increasing quantity of atmospheric CO₂ into the ocean."

Scientists expected that as atmospheric CO₂ increased, more and more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.

"As carbon dioxide dissolves（溶解） in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO₂ in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."

The seawater Dore and his colleagues have analyzed confirms what the theory predicts.

The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO₂ and then moved to those depths. Or there could be a biological explanation.

"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It's potentially catastrophic."

1.What can be the best title of the passage?

A．Sea Life Facing Danger                                  B．Climate Change Affecting Seawater
