鱼类研究者

When it was time for Eugenie to go to college, she knew she wanted to be an ichthyologist - a person who studies and works with fish.

到了克拉克上大学的时候，她已经决定做一个每天都和鱼一起学习和工作的鱼类研究者。

But the study also had several limitations. They note that although interreader reliabilities of white-matter and ventricular grades are good, estimates of sulcal grade tend to have greater interreader variability. The researchers also point out that the observed associations could be related to other differences related to fish consumption, such as a healthier lifestyle in general.

不过，此研究也有一些限制；他们指出，虽然不同判读者之间对於白质和心室等级的的信赖度不错，但脑回等级的评估在不同判读者之间有比较大的差异；研究者也指出，观察到的关联可能也与食用鱼类以外的不同状况有关，例如较健康的生活型态。

By analysing information contained in "food frequency" questionnaires, in which the women noted how often they ate 96 different foods, the researchers identified four major dietary patterns. They were:"healthy";"Western/Swedish"(red meat, processed meat, poultry, rice, pasta, eggs, fried potatoes and fish);"alcohol"(wine, liquor, beer and some snacks); and "sweets"(sweet baked goods, lollies, chocolate, jam and ice-cream).

通过分析&经常食用食物&的问卷调查的资料，她们写了经常食用的97种食物，研究者发现主要有四种饮食模式：建康食物；西式食物/瑞典食物（红色的肉类食物，加工过的肉类食物，家禽类，大米，面食，炸土豆和鱼类）；酒类（白酒，白兰地，啤酒和一些小吃）；甜点（烤的甜点、糖块、巧克力、果酱和冰激凌）。

However, researchers found that piranha most likely group together as a defense against such predator s as river dolphins, caimans and bigger fish, and not to engage in feeding-frenzies.

但是，研究者们发现食人鱼拉帮结伙更多的是为了抵御食肉动物——如河豚、凯门鳄和一些大型鱼类的攻击，而不是忙于觅食。

但是，研究者们发现水虎鱼大多喜欢结群是为了防御，好像河豚，凯门鳄和其他大型的鱼类，而并不是为了疯狂地扑食。

They found that fish consumption was also associated with trends toward lower incidence of subclinical infarcts.

他们发现，吃鱼也与降低无临床症状的梗塞有关，鱼与较佳的白质等级也有关，但是对於脑病变的标记－脑回和心室等级无关；研究者观察发现，吃炸制鱼类与任何无临床症状的脑部异常无显著关联。

WASHINGTON - Scientists unearthed a skull of the most primitive four-legged creature in Earth's history, which should help them better understand the evolution of fish to advanced animals that walk on land. The 365 million-year-old fossil skull, shoulders and part of the pelvis of the water-dweller, Ventastega curonica, were found in Latvia, researchers report in a study published in Thursday's issue of the journal Nature. Even though Ventastega is likely an evolutionary dead-end, the finding sheds new details on the evolutionary transition from fish to tetrapods. Tetrapods are animals with four limbs and include such descendants as amphibians, birds and mammals.

华盛顿-科学家挖掘出一副地球历史上最原始的四足生物头骨，这个有利于帮组他们更好理解鱼类进化成为更先进的陆地行走生物，这个有着三亿六千五百万年年龄的头骨，肩膀和水生生物的一部分骨盆，Ventastega curonica，在Latvia被发现，研究者一篇研究报告发表在在星期三出版的自然杂志上，尽管Ventastega 可能是一个进化的死胡同，这个发现给出了从鱼类到四足动物进化变迁过程的新细节，四足动物是使用四肢的动物并且包括下属的比如两栖类动物，鸟类和哺乳类动物。

Otolith is calcareous concretions in fish inner earsIts composition and structure are very stableIts accretional growth follows a circadian rhythm that is physiologically controlled and influenced by environmental conditionsOtolith acts as biological archives providing the basis for the reconstruction of individual life traits and environmental parametersThe paper focuses on fish otolith trace elements and their isotopes, general testing methods and the prospect and problems of its application in environmental detection in recent 20 years, hoping that it could provide researchers with some thoughts and could expand its potential application in environmental science.

鱼耳石是鱼类内耳中的钙质沉积体，组成和结构非常稳定，它的生长轮受其生理控制和环境条件影响有规律地昼夜生长。耳石可作为鱼类的生物学记录者并为重建其生活特征和环境参数提供依据。文中就近20年来国内外关于鱼耳石微量元素和同位素方面的研究热点、鱼耳石元素研究中常用的测试分析方法以及其在环境监测中的应用前景和存在的问题作一整理和综述，望能为广大耳石研究者提供一些思路和揭示其在环境科学中的广阔应用前景。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
