Passage 2Birds 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 fallsanywhere in a field or forest.How could we enjoy spring without the birds flitting busily in our garden or dropping by tocheck out the flowers in our urban window box Can you contemplate America without the soaringbald 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 themScavenging 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 birdswill be poisoned by lead bullets and lead fishing sinkers if we allow such objects to drop in theirfeeding 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 riversand 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 andbreeding grounds.Seabirds are among the most endangered vertebrate species on the planet, with the InternationalUnion for Conservation of Nature classifying 97 species as globally threatened, and 17 in the highestcategory of critically threatened. Of greatest concern are the pelicans of the southern oceans and thespectacular, 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. Thealbatross, cormorants and herons need us to stop over-fishing and compromising their normal foodsupply.The pelicans, penguins 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 of the food chain. At the end of the day, their fate will be our fate.Which of the following best describes the attitudeA.Humanistic.B.Subjective.C.Sentimental.D.Recriminatory.

单选题Some paleontologists claim that the discovery of what appear to be feathers in the fossil of an Archosaur could force a revision of current theories on the phylogeny of Archosaurs, alter conceptions of dinosaur skin surfaces, and require scholars to credit birds with a far earlier orion than previously thought.Arequire scholars to credit birds with a far earlier origin than previously thoughtBscholars may be required to credit birds with a far earlier origin than previously thoughtCrequire a crediting by scholars of birds with a far earlier origin than previously thoughtDcompared to what was previously thought, require scholars to credit birds with a far earlier originEcrediting birds with a far earlier origin than scholars had previously though
单选题Paleontologists hypothesize that modern birds evolved from the family of dinosaurs that included Tyrannosaurus rex. This hypothesis would be strongly supported if evidence that dinosaurs from this family had a body covering resembling feathers could be found, but so far no such evidence has been found. Which of the following, if true, would most help the paleontologists explain why no evidence of feathered dinosaurs has yet been found?AFossilized dinosaurs have shown many birdlike characteristics, such as bone structure and winglike arms.BIf birds are in fact the descendants of dinosaurs, then it can be argued that the dinosaurs never really died out.CFlying dinosaurs such as the Pteranodon, which is not thought to have been related to modern birds, do not appear to have had feathers.DSoft tissues such as skin and feathers do not fossilize like bones, and therefore are far less likely to have left permanent evidence in the fossil record.EThe thousands of dinosaur fossils excavated by paleontologists represent only a tiny fraction of the billions of dinosaurs that once lived.
