A tiny Alaska village has experienced a bm in turism in recent years as plar bears spend mre time n land than n Arctic sea ice.
Mre than 2，000 peple visited the nrthern Alaska village f Kaktvik in 2018 t see plar bears in the wild. The far nrth cmmunity lies in an area where increasingly higher temperature has sped up the mvement f sea ice, the primary habitat f plar bears. As ice has gradually mved t deep water beynd the cntinental shelf, mre bears are remaining n land t lk fr fd.
Plar bears have always been a cmmn sight n sea ice near Kaktvik, but villagers started nticing a change in the mid­1990s. Mre bears seemed t stay n land, and researchers began taking nte f mre female bears making hmes in the snw n land instead f n the ice t raise their babies. U．S. Fish and Wildlife Service bilgists began hearing reprts f the increasing number f plar bears in the area in the early 2000s. As mre attentin was given t the plight(困境) f plar bears abut a decade ag, mre turists started heading t Kaktvik.
“The village had fewer than 50 visitrs annually befre 2011，” said Jennifer Reed, f the Arctic Natinal Wildlife Refuge. “Tday we’re talking abut hundreds and hundreds f visitrs, many frm arund the wrld each year，” Reed said. Mst turists visit in the fall, when bears are frced tward land because sea ice is farthest away frm the shre. Bruce Inglangasak, a lcal hunter wh smetimes ffers wildlife­viewing turs, said he’s been ffering plar bear turs since 2004. Mst f his clients(客户) are frm China and Eurpe, as well as frm the lwer 48 U．S. states. Many turists stay several days in the village, which has tw small htels. The villagers have benefited a lt frm that. In turn, they prvide mre effective prtectin fr plar bears with financial supprt frm turism develpment.
1．What causes mre plar bears t stay n land in Kaktvik?
A．Fd shrtage.
B．Climate change.
C．Habitats’ mvement t shre.
D．Their preference fr land.
2．Hw did cmmn peple feel abut mre sight f bears n land?
A．Excited. B．Puzzled.
C．Cncerned. D．Shcked.
3．What can be inferred frm the last paragraph?
A．Htels in Kaktvik are in demand in autumn.
B．Kaktvik has abut 50 visitrs annually.
C．Inglangasak makes a living as a tur guide.
D．Turism affects the balance f nature.

Histrians and archaelgists have defined perids f human histry fr centuries by the technlgies r materials that made the greatest impact n sciety. This includes the Stne Age, the Brnze Age, and the Irn Age. But what age are we in nw? That questin can be answered with ne wrd fr sme researchers: Plastics.
“Plastic has redefined ur material culture and the artifacts we leave behind. It will be fund in stratified(分层的) layers in ur trash depsits(沉积层)．” That’s accrding t Jhn Marstn, an archaelgist.
The wide variety f synthetic plymers(合成聚合物) wuld nt exist if it weren’t fr human actin. Abut six billin tns f plastics have been made and spread arund the planet. They have been spread frm frests t ceans ever since the first plastic plymers were invented.
Plastics are ne f the mst significant changes that humans have made t the Earth’s makeup. Mst plastics dn’t easily degrade. This nly adds t the prblem. Recycling isn’t an adequate slutin. Nt all types f plastic are easily recyclable. And there are nly a few recycling plants that can prcess all varieties f plastic.
Accrding t Debra Winter, writer fr The Atlantic, this means that many f the materials thrwn int recycling bins can crss the planet several times befre they are prcessed. They are made int rugs, sweaters, r they are used t make ther bttles. Millins f tns f plastics are recycled every year, but millins mre end up in landfills r the cean. The prblem has reached the pint where it’s pssible that in just a few decades there might be mre plastic in the wrld’s ceans than fishes.
“Plastics have a suppsed lifespan f ver 500 years, s it’s safe t say that every plastic bttle yu have used exists smewhere n this planet, in sme frm r anther，” Winter writes.
The damage may already be dne. It may be t late fr human ppulatins wrldwide t change their plastic using ways. S the Plastic Age might sn take its place next t the Brnze Age and the Irn Age in the histry f human civilizatin.
4．Why d peple call ur age the Plastic Age?
A．Because plastics are nt naturally made.
B．Because humans create plastics.
C．Because plastics influence the wrld greatly.
D．Because histrians and archaelgists think s.
5．Accrding t the passage, hw are mst plastics dealt with currently?
A．They are recycled.
B．They are degraded.
C．They are thrwn away.
D．They are made int bttles.
6．What is the authr’s attitude t the Plastic Age?
A．Negative. B．Ambiguus.
C．Favrable. D．Uncncerned.
7．What is the main idea f this passage?
A．Plastics have ruined ur envirnment.
B．We must stp using plastics altgether.
C．Human beings are in the Plastic Age.
D．Plastics are significant t human develpment.

Encuraging life t blm (兴旺) in the middle f a desert is n easy task. But ne cmpany in the United Arab Emirates has cme up with a plan t prvide drinking water fr the state’s citizens. The cmpany intends t drag icebergs frm Antarctica t the gulf cast in rder t harvest its fresh water.
The cmpany plans t surce the massive blcks f ice frm Heard Island, arund 600 miles ff the cast f mainland Antarctica. It will then transprt them arund 5，500 miles t Fujairah, ne part f the UAE. One iceberg culd prvide enugh water fr ne millin peple ver five years, accrding t the cmpany.

An average iceberg cntains mre than 20 billin gallns f water, accrding t the cmpany. The iceberg takes a lng time t melt as 80 percent f it is under the water, while the white ice abve reflects sunlight and deflects(使转向) its heat. Blcks f ice will be placed in giant tanks, befre being prcessed. “This is the purest water in the wrld，” Mr. Al Shehi added.
8．What can we learn abut the UAE prject?

Hw many times have yu heard the expressin that mst peple spend mre time planning their vacatin than they d planning their lives? I wuld expand that expressin by adding that mst peple spend mre time "thinking" abut their vacatin than they d thinking abut what's imprtant in their life.
While rest and relaxatin are a must in living a balanced life, it's nt what we were created t d. After all, the Master Creatr tk his R&R(Rest and Recreatin)n the seventh day, nly after six days f"definitely directed thught".
Wallace D.Wattles wrte, "There is n labr frm which mst peple shrink(退缩）as they d frm that f sustained and cnsecutive thught; it is the hardest wrk in the wrld." And yet it is the first and primary labr f achievement.
My friend Mike Litman wrte an utstanding article this week. It's called The Millinaire Cmpsite and it analyzes ne f the big differences between successful peple and everyne else. He wrte," I recently visited a real estate multimillinaire Mgul. What did I see next t his desk? I saw his visin statement, alng with a list f what he values in life."
＂A few mnths ag, I interviewed an individual wh has sld prducts wrth ver a billin dllars n televisin. He tld me that he read his life and business visin and gals daily, and that he tk time t visualize exactly what he wanted t create each night befre falling asleep."
What is yur life's purpse r yur persnal missin statement? Is it written dwn? D yu review it and think abut it ften? Is yur life rganized arund yur purpse and a set f gals that supprt that purpse?
Withut life's purpse and gals, yu are like a ship withut a rudder(舵). There is pwer in yur purpse and in yur gals. It is the pwer that takes yu ver bstacles, and it is the fuel that prpels (驱使）yu tward the life yu envisin.
