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 （撤離） 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 （導致溫室效應的氣體排放），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 （易受影響的） 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 BB
A．rapid changes in earth's temperature.
B．bad effects of global warming.
C．moving of a country to a new place.

（2）According to scientists，the DIRECT cause of more and fiercer storms is BB
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 AA
A．a(chǎn)gree to reduce its greenhouse gas emissions.
B．sign an agreement with Tuvalu.
C．a(chǎn)llow Tuvaluans to move to the US.

Our school held an activity on last Sunday because it was "Earth Day".Hundred of students took part in it.I am one of them.First，the headmaster gave us a speech about how to protect earth—our home.Then we went hiking，this was about 15km.Although the hiking was very tired，none were left behind.It is no doubt that all of us like the activity.In the future，they will try hardly to protect the environment.We hope we will take part in more activity about caring about the globe.發(fā)布：2024/6/27 10:35:59組卷：0引用：1難度：0.5 -
2．Leading a sustainable （可持續(xù)的） lifestyle doesn't require you to have to make great changes to your home，and this kind of transformation doesn't have to be an exhausting exercise. （1）
Here are three of them.
（2）By using solar energy，you will make your home far more sustainable.Solong as there is the sun in the sky，the solar panels atop your house will catch the rays and then transform them into electricity.
Make changes to your water drinking habits.Have you ever thought about how many single-use plastic bottles you use a year？If you should ever perform such a count，you'd find yourself well into three figures，or maybe even four. （3）To be truly sustainable，you've to change your water drinking habits.
（4）More often than not，these types of straws are used only once before being got rid of and taking up valuable landfill space.
Reduce your transport emission （排放）.If you want to be a more sustainable traveller，you should seek to reduce the carbon emissions you produce by avoiding driving.Of course，avoiding motor vehicles entirely isn't always going to be a practical choice for you.There're，however，still things you can do to be more sustainable. （5）
You have the power to make a sustainable change to your lifestyle—take the above advice and don't waste it.
A．Turn to solar energy.
B．Avoid wasting valuable resources.
C．The best thing you can do is to cycle，walk，or run.
D．Two choices you have are sharing cars and taking public transport.
E．There're many easy and simple things you can do to be more sustainable.
F．Another change you can make in this instance is to stop using plastic straws.

3．The Sixth Extinction（滅絕） Extinctions，where entire species are wiped out，are not unusual in our Earth's history.In fact，over 90 percent of all species that ever lived are now extjye.aict.In the last 500 million years，there have been five times when life on Earth has almost ended.These include the third mass extinction，known as the"Great Dying"，which killed 90% to 96% of all species.And the fifth event，which occurred 66 million years ago，caused the death of the dinosaurs.The reasons for extinctions are varied.According to scientists，they include volcanic eruptions，asteroids （小行星） hitting the Earth from space，changes in sea levels，the decrease of the oxygen content of the sea and global warming.Many scientists say we are now entering the Earth's sixth mass extinction.This time，human activity will be to blame.
Although it is not unusual for species to die out naturally，the rate at which this is now happening is cause for concern.A 2015 study by scientists who were based at Brown University and Duke University in the US，looked at how quickly species die out due to natural causes，that is，the "background extinction rate".They found that human activity is causing species to die out1，000 times faster than normal.There is a long list of reasons why so many species are dying out：air and water pollution，forests being destroyed，factory farming and overfishing.It is clear that human activity has negatively affected all other species on Earth，including animals and plants.
If a sixth mass extinction occurs，scientists who have studied the issue believe that up to three quarters of all species on Earth could die out.Of course，as we humans depend on so many species for our survival，we would also be at risk of dying out.Our world and our lives depend on the balance in nature between animals and plants.Without forests，we would have no air to breathe and without clean water we would be unable to survive.
Can a sixth extinction be avoided？Experts say that it is not yet too late，if we take action now.If we want to survive，we need to stop destroying the planet that we live on and start to protect it.
（1）What are the reasons for extinction in the history？
（2）Why does the writer believe we will probably die out if 3/4 of the Earth's species die out？
（3）Please decide which part is false in the following statement，then underline it and explain why.
It is not unusual for species to die out naturally，so we human beings are not to blame.
（4）What actions can we take to avoid the sixth extinction？ （In about 40 words）發(fā)布：2024/6/27 10:35:59組卷：3引用：1難度：0.5
