You Contain Multitudes of Microplastics 　　你的身體帶有很多微塑料 　　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." 　　塑料具備重量輕、可塑性強、經(jīng)久耐用的特性。但它也因而越來越非常廣泛，一直出現(xiàn)在一些不應(yīng)該出現(xiàn)的地區(qū)——包含我們自己的身體。據(jù)一項新的科學(xué)研究顯示信息，人們已經(jīng)攝取很多說白了的“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. 　　該科學(xué)研究的創(chuàng)作者之一、澳大利亞維秘高校海洋生物學(xué)博士研究生基蘭·考克斯說“依據(jù)當(dāng)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 把它相當(dāng)于一粒米或一顆白芝麻，乃至是比他們也要小的物品。可是我應(yīng)說的是，人們已經(jīng)觸碰的大部分微塑料要比芝麻粒小得多。我認為，在我們剛開始探討這種大數(shù)字時，大家經(jīng)常會覺得很吃驚，由于許多這一類的物品大家是看不見的，最少用人眼是看不見的?！贝隧椏茖W(xué)研究被發(fā)布在《環(huán)境科學(xué)與技術(shù)》雜志期刊上。 　　Microplastics come from numerous sources. They can be pieces shed from larger plastics or they may have been designed small to begin with. 　　微塑料的來源于諸多。他們能夠是以很大的塑料上掉下來下的殘片，還可以是一開始就被設(shè)計方案得不大的顆粒。 　　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. 　　在她們的科學(xué)研究中，考克斯和他的團體查看了以往的科學(xué)研究參考文獻，這種參考文獻測算了大家常觸碰的化學(xué)物質(zhì)中帶有的微塑料總數(shù)，比如飲用水、桶裝水、糖、海貨，乃至是大家吸氣的氣體。 　　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. 　　此項剖析協(xié)助她們測算出了大家每一消化吸收的微塑料的標準總數(shù)。她們的剖析沒法將牛羊肉，禽畜、蔬菜水果和奶制品等普遍食品類列入在其中，由于現(xiàn)階段都還沒這種商品的相關(guān)數(shù)據(jù)信息。實際上，她們的科學(xué)研究只包攬了身體發(fā)熱量攝取占有率％的化學(xué)物質(zhì)。 　　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. 　　即便沒有充分考慮大家攝取的絕大多數(shù)化學(xué)物質(zhì)，科學(xué)研究顯示信息，大家每一最少攝取了.萬到.一萬微塑料顆粒物。 　　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，針對食用桶裝水并非飲用水的人而言，攝取量將更大。那麼，將這么多塑料攝取身體是不是安全性？專家尚不清楚。 　　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. 　　你能說，這僅僅對使用量的基本估算，是吧？因而，假如你從毒理和綠色生態(tài)毒理的視角去考慮到得話，使用量是一十分關(guān)鍵的考慮到要素，因而這僅僅基本估算，可是因為也有許多是大家不清楚的，這一大數(shù)字將會被比較嚴重小看了。 　　重點難點語匯 　　malleable? adj. 可鍛的；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

如何調(diào)整考研心態(tài)？生活中我們不會平白無故的心情不好，心態(tài)焦躁，一定是遇到什么不開心的事，考研也是，單純的調(diào)節(jié)心態(tài)只是治標不治本，當(dāng)下你調(diào)節(jié)好了，可能過段時間，還是會很產(chǎn)生同樣的問題，只有我們找出導(dǎo)致心態(tài)焦躁的原因，才能從根本上解決心態(tài)問題，記得高三時，我們面臨高考，壓力很大，但是卻很少焦躁，為什么，你有沒有想過？根本原因是老師已經(jīng)為我們安排好了學(xué)習(xí)計劃，每天干什么，每周干什么，每天過得明明白白，想到這你也許會明白了，心態(tài)焦躁的根本原因是計劃問題，安排問題，只要做好規(guī)劃并按著計劃走，心態(tài)問題自然就迎刃而解了。
