MorethanaquarterofAmericanchildren--andh
More than a quarter ofAmerican children--and half of black children--belong to families too poor to fully qualify for the ＄1,000-a-year child tax credit, which PresidentBush signed four years ago and has cited in arguing that his program of sweeping tax cuts helps low-income families, a new study has founD、With an annual value of $47 billion, the credit is the government’s largest children’s subsidy and one that has provoked sharp partisan fights. Many conservatives, viewing it solely as a tax cut, want to reserve the credit for families that owe federal income tax. Many liberals, vie-wing it as a broader children’s allowance, want to extend it to poorer workers, who they say need it most.
Still, the study found that the families of 19.5 million children were too poor to receive the full ＄1,000 benefit.About half get a partial benefit, and half get nothing. Newt Gingrich, the former Republican House speaker, expressed surprise at the racial gap. "That’s a stunning number," he said, referring to the half of black children who fail to receive the full credit. "I’d find a way to make sure those kids get the money as part of a broader post-Hurricane Katrina plan."
Framed as middle-class tax relief, the credit passed in 1997 and offered ＄500 per child to families that owed income tax. It was doubled in 2001 and made partly available to families too poor to have income tax bills. LenBurman, a co-director of the tax center and the study’s author, said it might actually exaggerate the amount going to the poor since it assumed all eligible families received the credit. In practice, studies suggest that poor and minority families claim tax credits at lower rates.
Told of the study, which will be published Monday, some conservatives repeated their opposition to making the credit more of an antipoverty program. Mr. Mitchell said that low-wage workers received a total of ＄39 billion a year from a similar program, the earned income tax credit. "It’s not like they’re not getting any redistribution from the government," he saiD、"We want less income redistribution, not more."Both sides in child tax credit debate have cast their arguments in moral terms. "The income gap is wide and growing," Ms. Snowe saiD、"We’re talking about giving a helping hand to families who through no fault of their own are at or near poverty." Mr. Mitchell of the Heritage Foundation said income redistribution was morally problematic, since it punished people for economic success. He also called it economically inefficient, arguing that it discouraged work among both rich and poor.

{{B}}Passage Seven{{/B}}
It is hard to track the blue whale, the ocean’s largest creature, Which has almost been killed off by commercial whaling and is now listed as an endangered species.Attaching radio devices to it is difficult and visual sightings are too unreliable to give real insight into its behavior.
So biologists were delighted early this year when with the help of the Navy they were able to track a particular blue whale for 43 days monitoring its sounds. This was possible because of the Navy’s formerly top-secret system of underwater listening devices spanning the oceans. Tracking whales is but one example of a exciting new world just opening to civilian scientists after the cold war as the Navy starts to share and partly uncover its global network of underwater listening system built over the decades to track the ships of potential enemies.
Earth scientists announced at a news conference recently that they had used the system for closely monitoring a deep-sea volcanic eruption for the first time and that they plan similar studies. Other scientists have proposed to use the network for tracking ocean currents and measuring changes in ocean and global temperatures. The speed of sound in water is roughly one mile a second--slower than through land but faster than through air. What is most important, different layers of. ocean water can act as channels for sounds, focusing them in the same way a stethoscope (听诊器) does when it carries faint noises from a patient’s chest to a doctor’s ear. This focusing is the main reason that even relatively weak sounds in the ocean, especially low- frequency ones can often travel thousands of miles.
The passage is chiefly about ______.A．an effort to protect an endangered marine species
B．the civilian use of a military detection system.
C．The exposure of a U. S. Navy top-secret weapon
D．A、new way to look into the behavior of blue whales

目前，估计每年大约有50000物种绝迹。牛津大学的地理学家尼克•密德尔顿博士说道，如果这种情况继续下去，它对所有生物的影响将可能是深远的。“所有物种都以某种方式互相依赖以生存。因此危险就在于，如果你从这个互相联系的非常复杂的网络上除掉一个物种，你很难预料这对对生态系统造成的连锁影响。所以，如果你失去了一个重要物种，那也许会引起大量其他物种的绝迹。” 麻烦的是对这问题还没有明显的解决办法。和全球气温上升以及臭氧大大减少这些问题不一样，如果政府进行干预，这两种情况町以通过减少废气的排放得以减弱，而保护生物的多样性却依然是一个十分棘手的问题。最新的想法是“可持续管理”，即指人类应该在保证每一物种有足够的个体存活下来以确保该物种得以延续的条件下，才能够利用动、植物种为自己谋利益。人们把可持续管理视为一种保护物种使之免于绝迹的实用而又经济的办法。这种办法使当地人们可以为了经济上的原因而失去保护动、植物，而不是依靠在很大程度上难以奏效的反对非法偷猎的规章制度。例如，在津巴布韦就有可持续管理项目来保护大象。外国游客为娱乐而杀这动物要付高额费用。这钱随后再交给发生射猎的地区居民。从理论上讲，由于牵涉到当地居民经济利益，他们会受到激励去保护大象而不是去非法偷猎或允许其他人去偷猎大象。
