　　You Contain Multitudes of Microplastics 　　你的身体带有很多微塑料 　　Plastic is lightweight, malleable, durable. But it has also become so widespread that it’s ending up in a lot of unwanted places—including our own bodies. That’s according to a new study, which found that humans are consuming a shocking amount of so-called "microplastics." 　　塑料具备重量轻、可塑性强、经久耐用的特性。但它也因而越来越非常广泛，一直出現在一些不应该出現的地区——包含我们自己的身体。据一项新的科学研究显示信息，人们已经摄取很多说白了的“微塑料”。 　　"Microplastics, the kind of current working definition, is plastic less than five millimeters. So people commonly equate that to something like a grain of rice or a sesame seed and down in terms of size class. I will say that most of the microplastics that people are interacting with are quite a bit smaller than the sesame seed size, which I think always kinds of shocks people when we start talking about the numbers because the kind of, you know, they can’t see a lot of these things, at least with the naked eye." Kieran Cox, a PhD candidate in marine biology at the University of Victoria in Canada and one of the authors of the study, which is in the journal Environmental Science & Technology. 　　该科学研究的创作者之一、澳大利亚维秘高校海洋生物学博士研究生基兰·考克斯说“依据当今的界定，微塑料指的是粒度低于mm的塑料。因此在尺寸上，大家一般 把它相当于一粒米或一颗白芝麻，乃至是比他们也要小的物品。可是我应说的是，人们已经触碰的大部分微塑料要比芝麻粒小得多。我认为，在我们刚开始探讨这种大数字时，大家经常会觉得很吃惊，由于许多这一类的物品大家是看不见的，最少用人眼是看不见的。”此项科学研究被发布在《环境科学与技术》杂志期刊上。 　　Microplastics come from numerous sources. They can be pieces shed from larger plastics or they may have been designed small to begin with. 　　微塑料的来源于诸多。他们能够是以很大的塑料上掉下来下的残片，还可以是一开始就被设计方案得不大的颗粒。 　　For their study, Cox and his team pulled together past scientific literature that calculated the number of microplastics in things we commonly consume, such as in tap and bottled water, sugars, seafood—even in the air that we breathe. 　　在她们的科学研究中，考克斯和他的团体查看了以往的科学研究参考文献，这种参考文献测算了大家常触碰的化学物质中带有的微塑料总数，比如饮用水、桶装水、糖、海货，乃至是大家吸气的气体。 　　This analysis helped them figure out the baseline amount of microplastics that people are consuming every year. They couldn’t include common foods like beef, poultry, vegetables and dairy in their analysis because data on them doesn’t exist yet. In fact, their study could only account for percent of people’s caloric intake. 　　此项剖析协助她们测算出了大家每一消化吸收的微塑料的标准总数。她们的剖析没法将牛羊肉，禽畜、蔬菜水果和奶制品等普遍食品类列入在其中，由于现阶段都还没这种商品的相关数据信息。实际上，她们的科学研究只包揽了身体发热量摄取占有率％的化学物质。 　　Even missing the majority of what people swallow, the research revealed that—at the very least—humans appear to consume somewhere between , and , microplastic particles every year. 　　即便沒有充分考虑大家摄取的绝大多数化学物质，科学研究显示信息，大家每一最少摄取了.万到.一万微塑料颗粒物。 　　That number goes up for people drinking bottled water rather than tap water. Now, is all this plastic ingestion safe? Scientists simply don’t know yet. 　　并且，针对食用桶装水并非饮用水的人而言，摄取量将更大。那麼，将这么多塑料摄取身体是不是安全性？专家尚不清楚。 　　This is kind of the first estimate of dose, you could say, right? So if you’re thinking in terms of toxicology and ecotoxicology, dose is a very important factor to think about, and so this kind of presents the first estimate, but it is very much an underestimate because of what we don’t know. 　　你能说，这仅仅对使用量的基本估算，是吧？因而，假如你从毒理和绿色生态毒理的视角去考虑到得话，使用量是一十分关键的考虑到要素，因而这仅仅基本估算，可是因为也有许多是大家不清楚的，这一大数字将会被比较严重小看了。 　　重点难点语汇 　　malleable? adj. 可锻的；可塑性的；有可塑性的；易融入的 　　sesame? n. 白芝麻，胡麻；通行卡 　　underestimate? vt. 小看；小看 n. 小看

如何调整考研心态？生活中我们不会平白无故的心情不好，心态焦躁，一定是遇到什么不开心的事，考研也是，单纯的调节心态只是治标不治本，当下你调节好了，可能过段时间，还是会很产生同样的问题，只有我们找出导致心态焦躁的原因，才能从根本上解决心态问题，记得高三时，我们面临高考，压力很大，但是却很少焦躁，为什么，你有没有想过？根本原因是老师已经为我们安排好了学习计划，每天干什么，每周干什么，每天过得明明白白，想到这你也许会明白了，心态焦躁的根本原因是计划问题，安排问题，只要做好规划并按着计划走，心态问题自然就迎刃而解了。
