正确答案: B

Think about.

题目：22.请阅读Passage 2,完成第1～5小题。 　　Passage 2 　　Birds are a critical part of our ecological system.But more than ever,birds are threatened byhuman pollution and climate change. 　　We need the birds to eat insects,move seeds and pollen around,transfer nutrients from sea toland,clean up after the mass death of the annual Pacific salmon runs,or when a wild animal falls anywhere in a field or forest. 　　How could we enjoy spring without the birds fiitting busily in our garden or dropping by to check out the fiowers in our urban window box? Can you “contemplate” America without the soaring bald eagle,or even those scavengers like the pigeons and gulls that clean up discarded food scrapson our city streets and waterfronts? How diminished our lives would be without “them”? 　　Scavenging eagles and condors need hunters to behave responsibly and bury,or remove,theremains of any shot deer peppered with fragments of lead bullets.loons,ducks and other water birds will be poISOned by lead bullets and lead fishing sinkers if we allow such objects to drop intheir feeding space. 　　All sea and shore birds,even the puffins and guillemots of the otherwise pristine Aleutians,need us to make sure that no other heavy metals,like mercury and cadmium,are dumped in rivers and make their way across the oceans. 　　Birds like the terns,knots and shearwaters that migrate between the far north and deep,deep,south of our planet need people everywhere to cease and desist from filling in their wetland fuelstops and rest stations,and from constructing golfing resorts and factories in their feeding and breeding grounds. 　　Seabirds are among the most endangered vertebrate species on the planet,with the International Union for Conservation of Nature classifying 97 species as globally threatened,and 17 in thehighest category of critically threatened.Of greatest concern are the pelicans of the southern oceans and the spectacular,but slow-breeding albatross. 　　Plastic bags must be eliminated from natural environments so sea and shore birds don'tmistakenly carry such debris back to feed their chicks,with invariably lethal consequences.The albatross,cormorants and herons need us to stop over-fishing and compromising their normal foodsupply. 　　The pelicans,pengujns and all the birds that inhabit,or visit,our coastlines need us to ensurethat we do not dump oil into gulfs and bays,or release so much carbon dioxide into the atmospherethat the oceans turn acidic and we lose the mussels and oysters,the mass of calcareous plankton thatfeeds so many creatures,and the coral reefs that nurture enormous numbers of edible species. 　　Think about it:We share this small green planet.As they fly,feed and nest,the birds monitorthe health of the natural world for us,provided that we,in turn,make the effort to access that keyinformation.The birds and humans are both large,complex and ultimately vulnerable organisms that inhabitthe top ofthe food chain.At the end of the day,their fate will be our fate.

解析：词汇题。根据第三段可知，作者的目的是让读者想象没有鸟类的生活会变成什么样，故推测contemplate的意思为“考虑，思量”。故本题选B。
