参考解析
解析：
句意：我们发现一些鸟在天暖和天寒的地区之间一年迁徙两次。migrate迁移，迁居，迁徙可指鸟、鱼等的迁徙，与bird和twice a year形成语义关系，符合句意。transfer迁移，转移，传递，调任，但迁移或转移的对象通常作宾语而不是主语。commute通勤，强调有规律地、频繁地来往于两地间。emigrate移居，迁居，指由本地移居他国。

Most animals have little connection with animals of different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership ( 伙伴关系 ) which does good to both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫 ) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals ( 珊瑚 ) of the sea. In their skins they have tiny plants act as "dustman", taking some of the waste products form. the corals and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are ever prevented from lighting so that they cannot live normally, the corals will die.1、Some birds like to sit on a sheep because ( ).A、they can eat its parasitesB、 they depend on the sheep for existenceC、 they enjoy traveling with the sheepD、 they find the position most comfortable2、The underlined word "they" in the last sentence of the first paragraph refers to ( ).A、birds and parasitesB、birds and sheepC、parasites and sheepD、sheep, birds and parasites3、What does the second paragraph mainly discuss? ( )A、Some animals and plants depend on each other for existence.B、 Some animals and plants develop their relationship easily.C、 Some plants depend on each other for fooD、 Some animals live better together.4、What does this article talk about? ( )A、Two kinds of animals for a partnership.B、Most animals only have connection with animals.C、The connection between the living things.D、Corals have some connection with plants.

Every year gray whales migrate from the Bering Sea in Alaska to the Baja Peninsula in Mexico.Eleven gray whales have died in the San Francisco Bay in the last three weeks．No one knows why the whales are dying.Last year 270 whales died along the whales'migration route．Many people think starvation is the cause．This year the dead whales seem to have more blubber(fat)on them.Twenty years ago,the gray whale was listed as an endangered species.Some scientists think that the larger number of whales makes it hard to find enough food．More whales create more pressure on the food supply,a supply that some scientists say may have dwindled as a result of the warm waters of El Nino.Most of the whales have been dead for many days before they are found and studied．This makes it hard to find the reason for death.65 whales have been seen in the San Francisco Bay Area this year compared to 17 last year．The whales could be dying from many diseases,but it may be over-population．About how many more whales have been sighted in the San Francisco Bay this year compared to last year?A.Twice as manB.Three times as manC.Half as manD.About the sam
Text 2 When people talk about a"north-south divide"in Britain they are usually referring to house prices,employment and the ratio of private-sector to public-sector jobs.The south scores higher on all such measures.But new data from the British Trust for Ornithology（BTO）,a research charity,hints at the growth of another north-south divide-this time to the north's benefit.Every 20 years the BTO produces a superbly detailed atlas of bird life in Britain and Ireland.The 2007 t0 2011 edition is cheery:more species are tallied than in previous atlases,and many birds are increasing in number.Compared with two decades ago,45%of regular native species are ranging more widely while 32%are living in smaller areas;the rest have stayed put.But the most striking news comes from the north.The overall populations of woodland,farmland and migrant perching birds are up in northern England and Scotland but down in the south.The same is true of individual species such as the garden warbler,bullfinch and swallow.The number of cuckoos,a closely-watched species,declined by 63%in England between 1995 and 2010 but by only 5%in Scotland.Raptors are faring especially well in the south,but their numbers are rising in most parts of Britain.Partly this reflects climate change,suggests Simon Gillings of the BTO.Some birds are drawn to warmer winters in Scotland and northem England;visiting migrants may stick around for longer.Hard though it may be to believe during a week of torrential rain,the south is becoming drier,pushing snipe northward.More efficient farming has squeezed some farmland species.Some birds find it harder to make homes in the south,too.Pressure on housing means dilapidated buildings and barns,handy for nesting,have been converted into human dwellings.Between 2006 and 2012 the number of vacant dwellings fell by 17%in London and by 12%in Kent.Over the same period the number of empty houses increased by 16%in Derbyshire and by 10%in Lancashire:Northern mining villages once full of workers are now sparsely populated,points out Ian Bartlett,a birdwatcher in Hartlepool,in north-east England.They have become hot spots for birds and the people who watch them.Culrural difference also plays a part,thinks Mark Cocker,an expert on birds.The"obsession with tidiness"is stronger in the south,he says.Fewer people cultivate gardens;they prefer to cover them in decking and remove weeds from between concrete slabs.Village greens are mowed short.In contrast,Scotland and northern England have more trees,grassland and wind-swept moors.Less popular with humans,rugged parts of the countryside are filling up with a winged population instead.The text mainly discusses_____A.birds thriving in EnglandB.new north-south divideC.culture difference between north and southD.climate change in England

共用题干第三篇Operation MigrationIf you look up at the sky in the early fall in the northern part of North America,you may see groups of birds.These birds are flying south to places where they can find food and warmth for the winter. They are migrating（迁徙）.The young birds usually learn to migrate from their parents. They follow their parents south.In one unusual case,however,the young birds are following something very different.These birds are young whooping cranes and they are following an airplane!The whooping crane is the largest bird that is native to North America.These birds almost disappeared in the 1 800s.By 1941,there were only about 20 cranes alive.In the 1970s,people were worried that these creatures were in danger of disappearing completely.As a result,the United States identified whooping cranes as an endangered species that they needed to protect.Some researchers tired to help.They began to breed whooping cranes in special parks to increase the number of birds.This plan was successful,There were a lot of new baby birds.As the birds became older, the researchers wanted to return them to nature.However,there was a problem:these young birds did not know how to migrate,They needed human help.In 2001,some people had a creative idea.They formed an organization called Operation Migration. This group decided to use very light airplanes,instead of birds,to lead the young whooping cranes on their first trip south.They painted each airplane to look like a whooping crane.Even the pilots wore special clothing to make them look like cranes.The cranes began to trust the airplanes,and the plan worked.Today,planes still lead birds across approxlmately 1,200 mniles(1,931 kilometers),from the United States-Canadian border to the Gulf of Mexico.They leave the birds at different sites.If a trip is successful, the birds can travel on their own in the future.Then,when these birds become parents,they will teach their young to migrate.The people of Operation Migration think this is the only way to maintain the whloopingcrane population.Operation Migration works with several other organizations and government institutes.Together,they as- sist hundreds of cranes each year. However,some experts predict that soon this won't be necessary.Thanks to Operation Migration and its partners,the crane population will continue to migrate.Hopefully,they won'tneed human help any more.Whooping cranes migrate in winter to___________.A:raise baby whooping cranesB:get human helpC:find warmth and foodD:lay eggs
