24、 do the hard work of raising their changeling young. But there is a difference. A cuckoo chick usually pushes the original nestlings out, so that it can monopolise the food brought by its unwitting adoptive parents. Cowbird chicks, by contrast, seem to tolerate their nestmates.That seems odd. So odd

25、, in fact, that Jeffrey Hoover and Scott Robinson of the Illinois Natural History Survey decided to look into the matter. What they found is that the host birds real chicks are pawns in a protection racket of a sort the Sicilian Mafia would be proud to have invented.The victims of the racket are pro

26、thonotary warblers. These birds do not reject cowbird eggs even though they look quite different from their own. That in itself is intriguing, for cuckoos, again in contrast to cowbirds, lay eggs that mimic those of their hosts. Dr. Hoover and Dr. Robinson demonstrated what was going on by erecting

27、182 warbler nestboxes at the top of narrow, greasy poles.The first phase of their study was observational. Over the course of six years, they watched 472 nests in which warblers had laid their eggs. Almost half of these were parasitised by cowbirds. But, parasitised or not, almost allprotected as th

28、ey were from ground-based predators successfully produced fledgling warblers.Then the experiment began. In the following seasons Dr. Hoover and Dr. Robinson removed cowbird eggs from some of the parasitised nests. At the same time, they reduced the diameter of the entrances to some of the nest boxes

29、, in order to deny admission to cowbirds (which are larger than warblers).Warblers whose nests were thus protected did well, raising an average of four chicks to maturity in the absence of a cowbird parasite. Nests from which cowbird eggs had been removed, but which lacked protection, did badly. In

30、fact, more than half of them were attacked. The eggs were pecked open and the nests themselves torn to pieces. Nests thus attacked yielded, on average, but a single fledgling, whereas those with a cowbird egg in them yielded three warbler fledglings. Paying protection money in the form of food for t

31、he cowbird nestling thus looks a good deal from the warblers point of view, and explains why cowbirds do not need to disguise their eggs to look like those of prothonotaries.The cowbirds dastardly Wicks do not stop at this protection racket, either, for a fifth of those warbler nests that had never

32、had cowbird eggs in them also got destroyed. Dr. Hoover and Dr. Robinson ascribe this behaviour to a strategy they call “farming“. If warblers lose a clutch, they will often produce a second. If a cowbird female fails to lay in a warbler nest in time for her egg to hatch with those of the host, she

33、can reset the clock in her favour by killing the first clutch. Even the Mafia never thought of that one.（分数：5.00）(1).Both cowbird and cuckoo chicks（分数：1.00）A.are raised and grow up in other birds nests.B.are laid in other birds nest and push the original nestlings out.C.grow up with the original nes

38、.D.kill the warblers eggs to reset the time for warblers to hatch.BText 2/BThree out of four British Bangladeshi children live below the poverty line. That was the biggest jolt in a series of sad reports on April 30th from the Joseph Rowntree Foundation. Their focus was the link between ethnicity an

39、d poverty, which they found to be pretty robust. Some 40% of those from ethnic minorities live in poverty, it said, if poverty is defined as receiving 60% or less of the median income. This is double the proportion of whites. Even Indians and Chinese were much likelier than whites to be poor, despit

40、e trouncing them at school.The struggle to escape poverty begins with a big decision: whether to seek paid employment or work for oneself. Historically there has been a strong ethnic divide. South Asian and Chinese immigrants have been quick to set up businesses, whereas black Africans and Caribbean

41、s have worked for others. Yet this pattern now appears to be breaking up. Chinese and Indian men seem to be ditching the takeaways and newsagents, but black Caribbeans and Pakistanis are keener than ever to go into business for themselves.Ken Clark and Stephen Drinkwater, the authors of the Rowntree

42、 report, identify various characteristics that incline workers to self-employment. Those who are born abroad or poorly qualified find it harder to get other jobs. Starting a business usually takes financial and human capital, so older people who own their own home and have families are more likely t

43、o set up shop. Educational achievement makes an especially big difference in Britain, where graduates snootily consider sell-employment a last resort for dimwitsunlike in America, where plenty of big brains make big bucks starting their own firms.If this is true, it is not surprising that Indians an

44、d Chinese are beginning to turn away from self-employment. Whizzes at exams, young and increasingly likely to have been born in Britain, the latest generation is more apt to become doctors and lawyers than restaurateurs. Black Africans and Caribbeans, meanwhile, still lag behind at school and as a g

45、roup are slightly older, which may explain their swerve into business. A boom in the construction industryin which much black self- employment is basedmay also have contributed, along with government efforts to boost black entrepreneurship.The puzzle is Pakistanis. Though they share some characteris

46、tics with Indians and Chineseincluding improved education levels and a youthful profile-they are moving the other way. “Relative to their qualifications, they seem to get lower returns on paid employment than other groups,“ says Mr Drinkwater. That they persist in self-employment may be due to a lac

47、k of more rewarding alternatives.Why dont they find well-paid jobs as easily as others? “Discrimination is the thing we assume is left,“ says Mr Clark. But there are other factors: The concentration of Pakistanis in depressed textile towns makes it harder to find employment, and unwillingness to move away compounds this. Religion may also play its part. Interestingly, white Muslims seem to experience the same
