It is rare for&a new animal species&to emerge in front of scientists& eyes. But this seems to be happening in eastern North America.
October 3rd | Science and technology
LIKE some people who might rather not admit it, wolves faced with a scarcity of potential sexual partners are not beneath lowering their standards. It was desperation[绝望;不顾一切,拼命] of this sort, biologists reckon, that led dwindling wolf populations in southern Ontario to begin, a century or two ago, breeding[生育;繁殖;孕育;导致] widely with dogs and coyotes[ka?'o?ti][郊狼;丛林狼;草原狼]. The clearance of forests for farming, together with the deliberate[故意的;蓄意的] persecution which wolves often suffer at the hand of man, had made life tough for the species. That same forest clearance, though, both permitted coyotes to spread from their prairie[大草原,大牧场;草原地带] homeland into areas hitherto exclusively[专有地; 排外地] lupine[狼], and brought the dogs that accompanied the farmers into the mix.
?&scarcity ['skers?ti]
n. 不足，缺乏; 稀少; 萧条
a time of scarcity物资短缺时期
?&beneath [b?'ni&]
prep.在&的下方; （表示等级）低于;

Flipping burgers is not beneath your dignity.

?&dwindle ['dw?ndl]
vi. 减少，变小，缩小; 衰落，变坏，退化
The number of people going to the cinema seems to dwindle steadily.
看电影的人数似乎在逐渐下降.
?&persecution [?p?:s?'kju??n]
n. 迫害或受迫害，烦扰; 苛求，困扰
It is worthwhile to note that both suffered persecution.
值得注意的是,双方都受到过迫害.
?&hitherto [?h?&?r'tu:]
adv. 到目前为止; 迄今; 至今
a hitherto unknown species of moth
迄今仍属未知种类的蛾
Interbreeding[异种交配;杂交]&between&animal species&usually leads to&offspring[后代;崽;幼苗]&less&vigorous[有力的; 精力充沛的]&than either parent&if they survive at all. But the combination of&wolf,&coyote&and&dog&DNA that resulted from this&reproductive[生殖的; 再生产的; 复制的] necessity[必要（性）; （迫切）需要; 必需品; 自然规律]&generated an exception[出现例外]. The consequence has been booming numbers of an&extraordinarily fit new animal&(see picture) spreading through the eastern part of North America.
Some call this&creature[生物，动物]&the eastern coyote. Others, though, have&dubbed&it the &coywolf&. Whatever name it goes by,&Roland Kays&of&North Carolina State University[北卡州立大学], in&Raleigh,&reckons&it now numbers in the millions.
?&dub [d?b]
vt. （以剑触肩）封&为爵士; 授予称号; 起绰号; 配音
Mulligan will dub me a new name: the bullockbefriending bard.
穆利根会给我起个新外号:阉牛之友派&大诗人&.
The mixing of genes&that has created the&coywolf&has been more rapid,&pervasive&and transformational[转换的，转换生成的]&than many once thought.&Javier Monz&n, who worked until recently at&Stony Brook University&in New York state (he is now at&Pepperdine University, in California) studied the genetic make-up of 437 of the animals, in ten north-eastern states plus Ontario. He&worked out&that, though coyote DNA&dominates[支配,主导;影响;占有优势],&a tenth of[十分之一]&the average coywolf&s&genetic material[遗传物质]&is dog and&a quarter[四分之一]&is wolf.
?&pervasive [p?r've?s?v]
adj. 普遍的; 扩大的; 渗透的; 弥漫的;

The DNA from both wolves and dogs (the latter mostly large breeds, like Doberman Pinschers[杜宾犬] and German Shepherds[德国牧羊犬]), brings big advantages, says Dr Kays. At 25kg or more, many coywolves have twice the heft of purebred coyotes. With larger jaws, more muscle and faster legs, individual coywolves can take down small deer. A pack of them can even kill a moose[大角麋，驼鹿].
?&heft [heft]
n. 重量，体积;
vt. 举&以掂重量; 举起

?&jaw [d??]
n. 下巴; 颌
His jaw was broken after he was hit on the head.
他的头部受重击之后下颌骨折了。
Coyotes&dislike&hunting in forests.&Wolves&prefer&it. Interbreeding has produced an animal skilled at&catching prey[捕捉猎物]&in both&open terrain[开阔地形]&and&densely wooded areas[密林地区], says Dr Kays. And even their cries[喊，叫]&blend&those of their ancestors. The first part of a&howl[嚎叫，咆哮]&resembles[像,类似于]&a wolf&s (with a deep&pitch[最高点; 音高]), but this then turns into a&higher-pitched, coyote-like&yipping[犬吠，叫喊].
?&blend [bl?nd]
vi. 掺杂; 结合; 相配，相称
She felt she would blend in nicely.
她觉得自己可以很好地融入进来。
The animal&s range has&encompassed&America&s entire&north-east,&urban areas&included, for at least a decade, and is continuing to expand in the&south-east&following coywolves& arrival there half a century ago. This is&astonishing[惊人的].&Purebred&coyotes never managed to establish themselves east of the&prairies[大草原,大牧场;草原地带]. Wolves were&killed off&in eastern forests long ago. But by combining their DNA, the two have&given rise to&an animal that is able to&spread into&a vast and otherwise&uninhabitable&territory[不适于居住的领地]. Indeed,&coywolves&are now living even in large cities, like&Boston,&Washington&and&NewYork. According to&Chris Nagy&of the&Gotham Coyote Project, which studies them in New York, the&Big Apple[纽约城]&already has about 20, and numbers are rising.
大苹果城即Big Apple，是美国纽约市的别称。
?&encompass [?n'k?mp?s]
vt. 围绕，包围; 包含或包括某事物; 完成
The sounds of life encompass his path.
他在路上只听得四面八方都是人声.
Even&wilier
Some&speculate&that this&adaptability[适应性; 合用性]&to city life is because coywolves& dog DNA has made them&more tolerant of people and noise, perhaps&counteracting&the genetic material&from wolves&an animal that dislikes humans. And&interbreeding&may have helped coywolves&urbanise[使都市化，使文雅]&in another way, too, by broadening the animals& diet.&Having&versatile&tastes is handy for city living. Coywolves eat&pumpkins[南瓜],watermelons[西瓜]&and other&garden produce[农作物], as well as&discarded&food. They also eat&rodents[啮齿目动物]&and other&smallish[有点小的，短小的]&mammals[哺乳动物]. Many lawns&and&parks&are kept clear of thick&underbrush[灌木丛; 林下灌丛], so catching squirrels[松鼠]&and pets is easy. Cats are typically eaten&skull[颅骨，头盖骨; 脑袋; 脑子]&and all, with clues left only in the&droppings[排泄物; 滴下物; 动物粪便].
?&wily ['wa?li]

He's a wily old fox.
他是个诡计多端的老狐狸。
?&speculate ['sp?kj??let]

vi. 投机; 推测; 思索;
It's always hard to speculate about the future.

He is sparkling and versatile in front of the camera.

? discard [d?s'kɑ:rd]
vt. 丢弃，抛弃; 解雇; 出牌;
We should discard old beliefs.

Thanks to this&bounty, an&urban coywolf&need&occupy[占领; 使用]&only half the territory&it would require in the countryside. And getting into town is easy. Railways providecorridors[走廊，通道]&that make the trip simple for animals as well as people.

We received a bounty from the government.

Surviving once there, though, requires a low profile.&As well as having small territories, coywolves have&adjusted to&city life by becoming&nocturnal. They have also learned the Highway Code[高速公路规则], looking both ways before they&cross a road. Dr Kays&marvelsat&this &amazing&contemporary[当代的，现代的]&evolution story that&s happening right underneath our nose&.
? nocturnal [nɑ:k't?:rnl]

vt.& vi. 惊奇，对&感到惊奇

The tourists marvel at the beauty of the lake.
游客们惊叹这条湖的美丽.
Whether the coywolf actually has evolved into[演变;进化;发展] a distinct species[特殊物种;新物种] is debated. Jonathan Way, who works in Massachusetts[马萨诸塞州] for the National Park Service, claims in a forthcoming paper that it has. He thinks its morphological and genetic divergence[形态和基因上的分化] from its ancestors is sufficient to qualify. But many disagree. One common definition of a species is a population that will not interbreed with outsiders. Since coywolves continue to mate with[交配] dogs and wolves, the argument goes, they are therefore not a species. But, given the way coywolves came into existence, that definition would mean wolves and coyotes should not be considered different species either&and that does not even begin to address whether domestic dogs are a species, or just an aberrant form of wolf.
? morphological [?m?:f?'l?d??kl]
adj. &生&&语&形态学的，形态的
Correlation of morphological factors with injury is important.
形态因素与受害的相互关系很重要.
? aberrant [&'b?r?nt, '&b?-]
adj. &生物&异常的; 畸变的;离开正路的; 与正确（或真实情况）相背的;
I saw that the insects and spiders were displaying the same kind of aberrant behavior.
我看到昆虫和蜘蛛正在表现出相同反常的行为.
物种，是生物分类学研究的基本单元与核心。它是一群可以交配并繁衍后代的个体， 但与其它生物却不能交配，不能性交或交配后产生的杂种不能再繁衍。&&摘自百度百科
In reality, &species& is a concept invented by human beings. And, as this argument shows, that concept is not clear-cut. What the example of the coywolf does demonstrate, though, is that evolution is not the simple process of one species branching into many that the textbooks might have you believe. Indeed, recent genetic research has discovered that even Homo sapiens[智人(现代人的学名)] is partly a product of hybridisation[杂交，杂种培植，配种]. Modern Europeans carry Neanderthal genes[尼安德特人基因], and modern East Asians the genes of a newly recognised type of early man called the Denisovans[丹尼索瓦人]. Exactly how this happened is unclear. But maybe, as with the wolves of southern Ontario, it was the only way that some of the early settlers of those areas could get a date.
? clear-cut ['kl?r'k?t]
adj. 轮廓鲜明的; 清晰的;
v. 清场伐木; 为开辟空地而砍伐（树木）;
There is no clear-cut answer to this question.
这个问题没有确切的答案。
尼安德特人(Homo neanderthalensis)，常作为人类进化史中间阶段的代表性居群的通称。尼安德特人是现代欧洲人祖先的近亲，从12万年前开始，他们统治着整个欧洲、亚洲西部以及非洲北部，但在两万四千年前，这些古人类却消失了。
丹尼索瓦人(Denisovans)是生活在上一个冰河时代的人类种群，她属于一个全新的人类种群。通过对古代遗留的牙齿和指骨化石提取的DNA进行分析，科学家证明了丹尼索瓦人的存在，该研究被《科学》杂志（Science）评为2012年度十大科学突破之一。

现在没有听说过买英语电子词典的了。基本都是小语种，什么德语，法语了...
我当初用的是诺亚舟，就是为了上课方便，后来毕业了，就卖掉了。
要是你是为了方便的话，可以买一个，要是想要学好英语，千万别买，买一本厚实的英语词典，慢慢翻吧。实话，不骗你。

其实我想买个电子辞典方便点可以带着身上，遇到不会的单词查下，省的翻那么厚的英语字典了。
还有就是客户来的时候，有的单词说不上来，也可以临时查一下。上次老外来，送他回酒店的路上，他问我什么学历，我想说大学本科来着，undergraduate， 可是一想这词怎么像未毕业的，没说。而master， 好像是是硕士，怎么办呢，算了，就说硕士吧。。。感觉特糗，这么简单的单词也忘了。
那次后，我就特想买个电子辞典在身边了

我们如何挑选一台适合自己所需的呢？结合电子词典的各种功能，选择品牌的就没错，我们在考察了内置词典的权威性后，消费者就需要考虑产品的出身了。业精于专，专业当然就可以出更高品质，而且大企业也具备良好的售后服务和维修保障能力，这些方面非常重要，而且并非任何一个厂家都能做到。电子词典属于实用性产品，提醒消费者一定要选择那些知名度高，信誉好的品牌，像我帮你到maigoo品牌排行网上面找到的：卡西欧Casio，步步高，名人MEIJIN，诺亚舟Noah，文曲星 等2012最新品牌，都是值得选购的品牌，楼主可以去看看，我给我弟弟买的是步步高的，很出名大牌子，质量和用起来都很不错的，如果还需购买的话不妨去购物网goo55上面看下一些购物导航精华，我就是这么选的。。
