本单元的引言出自印度国父甘地（Mhandas K. Gandhi）。地球是人类生活的家园，人类的生存和发展必须依赖自然环境和自然资源。因为贪婪，人类过度开采自然资源，造成环境破坏、生态失衡、资源枯竭，最终受害的还是人类自己。人类只有坚持科学发展观，适度利用资源，我们生存的环境才会逐渐好起来。
Earth prvides enugh t satisfy every man’s needs, but nt every man’s greed. — Mhandas K. Gandhi
地球所提供的物质财富足以满足每个人的需求，却不足以满足每个人的贪欲。——莫罕达斯·卡拉姆昌德·甘地

I haven’t seen this pht, but I have seen phts like it. The stry is that the plar bear starved t death because it culd nt find enugh t eat.

CLIMATE CHANGE REQUIRES THE WORLD’S ATTENTIONWe have knwn abut climate change fr decades. There is little dubt that Earth is getting warmer and warmer (see the graph). A warming cean and atmsphere alng with melting ice and rising sea levels prvide evidence f a dramatic change in the glbal climate.
Evidence f climate change
Lk at paragraph 2 and find ut its main idea.
In 2013, a lt f peple were shcked by a news pht f a dead plar bear that was fund n Nrway’s Arctic island f Svalbard. Accrding t the scientists wh fund its dead bdy, all that remained f the plar bear was “skin and bnes”. An expert wh has studied plar bears fr many years said that frm the psitin f its dead bdy, the bear appeared t have starved and died. Experts claimed that lw sea-ice levels caused by climate change meant the bear culd nt hunt seals as befre, s it had t travel greater distances in rder t find fd. This alarming case shwed hw the increase in temperature had an impact n Earth’s eclgy.
One f the victims f climate change
Lk at paragraph 3 and find ut its main idea.
Then what is causing the increase in the glbal average surface temperature? Climate scientists ften mentin a key climate prcess called the “greenhuse effect”, which has tw cmmn meanings: the “natural” greenhuse effect and the “man-made” greenhuse effect. The “natural” greenhuse effect refers t the fact that heat frm the sun enters the atmsphere and warms Earth’s surface as shrt-wave radiatin. The heat is released back int space at lnger wave lengths. Greenhuse gases in the atmsphere, such as methane and carbn dixide, trap sme f the heat, keeping Earth’s climate warm and habitable. Withut this prcess, Earth culd nt sustain life. Hwever, the “man-made” greenhuse effect has nw becme a big prblem. When peple prduce huge amunts f extra greenhuse gases by burning fssil fuels, mre heat energy is trapped in the atmsphere and causes Earth’s surface temperature t rise quickly.
Causes f climate change
Lk at paragraph 4 and find ut its main idea.
There is strng and cmprehensive evidence that the rise in temperature has led t an increase in extreme weather and natural disasters wrldwide, nt nly causing serius damage, but als csting human lives. Climate scientists have warned that if we d nt take apprpriate actins, this warming trend will prbably cntinue and there will be a higher price t pay. In fact, news reprts are frequently bradcast abut extreme rainstrms and heatwaves causing deaths and ecnmic lsses.
Effects f climate change
Lk at paragraph 5 and find ut its main idea.
Cntinued greenhuse gas emissins will result in further warming and lng-lasting changes t the glbal climate. This requires the attentin f peple all ver the wrld. Gvernments need t cnsider making plicies and taking apprpriate actins and measures t reduce greenhuse gas emissins. We as individuals can als reduce ur “carbn ftprint” by restricting the amunt f carbn dixide ur lifestyles prduce. It is ur respnsibility t seize every pprtunity t educate everyne abut glbal warming, alng with its causes and impacts, because this is the mst serius issue affecting all f us n this planet. S what will yu d t help?

1. What happened t the plar bear in the pht? Why did the writer write abut it?2. Can yu use yur wrds t describe hw climate change have influenced the plar bear’s life?
The plar bear in the pht died f starvatin. The writer wrte abut it because it shwed ne f the effects f rising temperatures due t climate change.
3. Why is the “natural” greenhuse effect imprtant and necessary?4. What are the cnsequences f high greenhuse gas emissins?5. Why did the authr mentin the climate scientists’ warning?6. What is the authr’s purpse f writing this text?
The “natural” greenhuse effect is imprtant because it warms the Earth’s surface and keeps it habitable.
High greenhuse gas emissins lead t mre heat energy being trapped in the atmsphere and rising temperatures.
Because it is essential that we take actin and s it needs t be brught t everyne’s attentin.
