Ⅰ.阅读理解

The world is getting warmer.Animals have begun to change in response to the new condition.And some of them have become smaller.Some scientists thought this might be an adaptation to a warmer world;smaller bodies should be able to lose heat better.But now a new study published in Science has found that for red knot birds,that’s not the case.

Ecologist Jan van Gils and his colleagues have been studying these birds for 33 years.Over the course of their research,van Gils and his team have found that in Russia where the red knots summer,snowmelt and spring have been advancing by half a day per year on average.Over more than thirty years,the researchers caught and measured nearly 2,000 birds.In years when the snowmelt had arrived particularly early,the birds were likely to be smaller and have shorter bills(鸟嘴).

The birds leave the coast of Western Africa,where they winter,and fly north

toward Russia with no clue as to what the weather is like there.The birds are supposed to arrive in spring,so they can lay their eggs and when their chicks hatch out,there will be a wealth of arthropod(节肢动物) insects to feed their young.

But even though the red knots are advancing their arrival date by about a quarter of a day per year,it is not enough to keep up with the snowmelt.And in years when the snowmelt arrives early,the arthropods reach the greatest quantity before the birds need them.Therefore,chicks miss out on eating well and they grow up to be smaller and have shorter bills.

Being smaller and ha ving a shorter bill isn’t a problem in Russia—but it is in Africa.There,adult birds feed on thin-shelled bivalves(双壳贝类),Loripes lucinalis.But the bivalves are buried deep.However,other options,Dosinia isocardia bivalves and seagrass rhizomes(根茎),which only the youngest birds rely on,are not abundant or nutritious.

Van Gils and his colleagues found that,in their first year,shorter-billed red knots don’t survive as well in Africa.“A few short-billed birds make it,”van Gils says,“but the majority of birds that survive are the long-billed birds.”

1.Jan van Gils and his colleagues reached the conclusion by .

paring red knots with other birds

B.dividing 2,000 red knots into several groups

C.watching and examining red knots for three decades

D.analyzing studies that have been published in Science

2.What influence does early snowmelt have on red knots?

A.Their chicks don’t have enough to eat.

B.Their eggs take more time to hatch out.

C.They need to find other places for summer.

D.They arrive in Russia half a day earlier each year.

3.Few adult short-billed red knots survive in Africa because .

A.they can’t find arthropod insects to eat

B.they can’t access Loripes lucinalis bivalves

C.the Dosinia isocardia bivalves they need are rare
