一种鱼

Concern about the silver or bighead species of Asian carp led to calls even before Thursday to close the waterway connecting the lakes to the Mississippi -- an unprecedented step that could disrupt the movement of millions of tons of coal, grain and other goods.

出于对鲢鱼和鳙鱼这两种亚洲鲤鱼的担忧，当地政府在周四下达通知，封锁连接五大湖与密西西比河的水道--这一前所未有的做法将影响到数百万吨煤矿，谷物以及其他货物的运输。

The condition factors of the saury differed significantly among the 6 landed size-classes of Taiwan with the largest in the No.1 size-class (0.635±0.043), followed by the Extra-large size-class (0.608±0.048), and the smallest homogeneous group in the No.4 (0.514±0.036) and No.5 (0.505±0.029) size-classes.

肥满度在这六种秋刀鱼缷鱼规格间有显著差异，最大肥满度出现在一号型(0.635±0.043)，特大型则居次(0.608±0.048)，最小群为由四号型(0.514±0.036)与五号型(0.505±0.029)所组成的同质群。

Pelican Any of various large, web-footed birds of the genus Pelecanus of tropical and warm regions, having a long straight bill from which hangs a distensible pouch of skin for catching and holding fish.

Lakes spill from mountain gorges into frigid streams that work their way through pine-needled forest floors and over lichen6-covered boulders, providing water, food, or habitation to the white-tailed deer, the porcupines and moose, the rabbits, squirrels, raccoons, bobcats, beavers, a variety of fish and many kinds of birds that inhabit New England's wooded hills and mountains.

湖泊从峡谷奔流而出，变成一条条寒冷的小溪，流过布满松针的林地和长满青苔的巨砾，为生活在新英格兰大大小小青山之间的白尾鹿、豪猪、驼鹿、兔子、松鼠、浣熊、美洲野猫、河狸、各种各样的鱼以及许多种鸟类提供了水、食物和栖息地。

New material indicates differing ontogenetic trajectories for their forelimbs: In Ichthyostega, the pattern of muscle attachment processes on small humeri resembles that in "fish" members of the tetrapod stem group such as Tiktaalik, whereas large humeri approach the tetrapod crown-group condition; in Acanthostega, both small and large humeri exhibit the crown-group pattern.

过去，研究人员相信Acanthostega是在化石记录中最像鱼的陆地动物，但这一有关Ichthyostega 迁徙前肢的新发现表明，Ichthyostega 应该在进化树上占有一个更基底的位置，而其它的种系（如Acanthostega）可能是从Ichthyostega 所进化而来，而非反过来的情景。

The results show that Ig molecular weight of Amur sturgeon, Chinese sturgeon and Huso sturgeon is 867kD, 896kD and 924kD respectively. Heavy chain molecular weight of Ig in the three sturgeons' serum is all 88kD and light chain of Amur sturgeon and Chinese sturgeon is 29kD, but there is an extra light chain of 26kD in Huso sturgeon serum.

PAGE及SDS-PAGE的结果显示：史氏鲟，中华鲟和达氏鳇IgM的相对分子量分别为867kD，896kD和924kD；3种鲟鱼Ig的重链分子量均为88kD，都具有29kD的轻链，其中达氏鳇还另有一分子量约为26kD的轻链蛋白。

Now transmuted, we swiftly escape, as Nature escapes; We are Nature—long have we been absent, but now we return; We become plants, leaves, foliage, roots, bark; We are bedded in the ground—we are rocks; We are oaks—we grow in the openings side by side; We browse—we are two among the wild herds, spontaneous as any; We are two fishes swimming in the sea together; We are what the locust blossoms are—we drop scent around the lanes, mornings and evenings; We are also the coarse smut of beasts, vegetables, minerals; We are two predatory hawks—we soar above, and look down; We are two resplendent suns—we it is who balance ourselves, orbic and stellar—we are as two comets; We prowl fang'd and four-footed in the woods—we spring on prey; We are two clouds, forenoons and afternoons, driving overhead; We are seas mingling—we are two of those cheerful waves, rolling over each other, and interwetting each other; We are what the atmosphere is, transparent, receptive, pervious, impervious: We are snow, rain, cold, darkness—we are each product and influence of the globe; We have circled and circled till we have arrived home again—we two have; We have voided all but freedom, and all but our own joy.

我俩，我们被愚弄了这么久我俩，我们被愚弄了这么久，可现在变了，我们迅速逃走，像大自然一样逃走，我们就是大自然，我们离开这里已经很久，但是如今回来了，我们变成植物、树干、树叶、树根和树皮，我们被安置在地里、我们是岩石，我们是橡树，我们并排地生长在林中的空地，我们吃草，我们是野牛群中的两只，如大家一样自然，我们是在海中一起游泳的两条鱼，我们是刺槐的花朵，我们早晚在小巷周围散发香气，我们也是兽类、植物、矿物的粗劣斑点，我们是两只肉食的苍鹰，我们翱翔在高空，俯视下面，我们是两个灿烂的太阳，我们在像星球般平衡着自己，我们是两颗彗星，我们张牙舞爪地在树林巾梭巡，我们向猎物跃进，我们是午前午后在上空奔驰的两朵云，我们是交混的海洋，我们是两个欢乐的浪头，在互相浇泼和连环翻滚，我们是大气、明澈而善于接受，有时能穿透，有时不能，我们是冰雪，雨水，寒冷，黑暗，我们是地球上的每种势力和产品，我们绕了一圈又一圈，最后我们又回到家里，我俩，我们避免了—切，除了自由和我们自己的欢欣。
