A recent study published in the jurnal EnvirnmentalScienceandTechnlgy fund micrplastics in mre than 90% f the packaged fdgrade salt—als knwn as table salt—fr sale in stres. The team, frm ROK's Inchen Natinal University and Greenpeace East Asia, sampled 39 brands f salt harvested in 21 cuntries. Only three f the samples had n micrplastics. They are a sample f refined sea salt frm Taiwan, China, a sample f refined rck salt frm Chinese mainland, and a sample f unrefined sea salt frm France.
Scientists have been finding micrplastics in salt fr years, including in salt frm the cuntries and regins in Asia, Eurpe and Africa. Salt made in cuntries in Asia had by far the mst micrplastics f all the samples, which crrelates with where plastic mst ften enters the cean. Nine f the tp 10 sea salt samples with the mst micrplastics came frm Asian cuntries.
“The results indicate that nt nly is Asia a ht spt f glbal plastic pllutin, as previus studies have suggested, but als that sea salt can be a gd indicatr f plastic pllutin by lking at where the salt was prduced，” the researchers write.
Based n their results, the researchers estimate that the average adult ingests abut 2，000 pieces f micrplastic in salt per year. But, they write, that still nly represents a fractin f the micrplastics a persn is likely t cnsume.
Micrplastics have als been fund in beer and fish nw in additin t salt. Previus research revealed that micrplastics have been fund in tap water, mllusks and bth indr and utdr air. All tgether, thse five pathways add up t an average 32，000 pieces f micrplastic ingested per year per persn. Inhaling (吸入) micrplastics in the air is by far the largest cntributr—peple ingest rughly fur fifths f the micrplastics that enter their bdies thrugh this rute.
Given thse ther surces f expsure, micrplastics in table salt amunt t abut 6% f a persn's ttal micrplastics ingestin, the researchers write.
5．What des the underlined wrd “They” prbably refer t?
A．Particular types f micrplastics.
B．Particular kinds f table salt.
C．Brands f unrefined sea salt.
D．Brands f refined sea salt.
6．What d researchers think f mst Asiamade salt accrding t the text?

Ⅱ.单句语法填空
1．答案与解析：t add 句意：导演同意把恶作剧加到播放单上。agree t d sth.意为“同意做某事”。
2．答案与解析：t have been 句意：那个男人声称昨天在超市购物时受到了很差的对待。claim后面接不定式作宾语，因为这件事已经发生，用不定式的完成式。

【语篇解读】 本文是一篇说明文。美国加州官员表示，他们将在一个地震预警系统上花费4 000多万美元。此预警系统将让公众知道可能会发生的地震。
1．答案与解析：C 细节理解题。根据第二段中的“the state had already put in place 70 percent f 1，115 sensrs”可知，该州已经安装了全州所需的1 115个传感器的70%，约为780个。
2．答案与解析：D 细节理解题。根据第三段的最后一句“Cmmunities farthest frm the epicenter f a quake wuld receive the earliest warning.”可知，离震中最远的地方将收到最早的地震警告。也就是说，离震中越远，该系统工作效果越好。
3．答案与解析：B 意图态度题。根据最后一段第一句中的“Jhn Wallace said there are many pssible uses f the early warning system”可知，此人说，预警系统有许多潜在的用途，说明此人对该系统持积极肯定的态度。
4．答案与解析：C 标题概括题。根据第一段“Califrnian fficials say they will spend mre than $40 millin n an earthquake early warning system.”可知，文章谈论的话题是加利福尼亚州将部署一个地震预警系统。
【长难句分析】
Califrnia Gvernr Gavin Newsm made an annuncement after Friday's quake that the state had already put in place 70 percent f 1，115 sensrs needed fr a statewide system.
句意：加利福尼亚州州长加文·纽森在周五的地震后发表了一项声明。他说，全州范围内该系统(地震预警系统)需要1 115个传感器，而该州已经安装了其中的70%。
句法分析：该句为主从复合句，句子主干为Califrnia Gvernr Gavin Newsm made an annuncement; that the state had a statewide system为that引导的同位语从句，对annuncement进行解释和说明。

【语篇解读】 本文是一篇说明文。塑料垃圾泛滥已经给环境带来灾难，也威胁着人们的健康。塑料由于难以降解，最终会以塑料微粒的形式进入我们的身体。最新研究显示，就连我们每天都要摄入的食盐也难逃塑料污染。你每年从食盐中吃进约2 000个塑料微粒，你敢相信吗？
5．答案与解析：B 词义猜测题。根据画线词所在句“They are a sample f refined sea salt frm Taiwan, China, a sample f refined rck salt frm Chinese mainland, and a sample f unrefined sea salt frm France.(它们是来自中国台湾的精制海盐样品，来自中国大陆的精制岩盐样品，以及来自法国的非精制海盐样品)”可知，这里既包括“精制海盐”又包括“非精制海盐”，可排除C和D两项；A项张冠李戴，错误地认为是“塑料微粒”。
6．答案与解析：A 细节理解题。根据第二段第二句“Salt made in cuntries in Asia had by far the mst micrplastics f all the samples, which crrelates with where plastic mst ften enters the cean.”可知，所有样品中含塑料微粒最多的食盐出自亚洲国家，这与亚洲的塑料最常进入大海有关。故选A。
7．答案与解析：C 细节理解题。根据文章第三段中的“but als that sea salt can be a gd indicatr f plastic pllutin by lking at where the salt was prduced”可知，研究结果发现，通过查看其生产地，海盐可以很好地说明当地塑料污染的严重程度。
8．答案与解析：D 推理判断题。根据倒数第二段中“Micrplastics have als been fund in beer and fish nw in additin t salt. Previus research revealed that micrplastics have been fund in tap water, mllusks and bth indr and utdr air.”可知，除了在盐里，塑料微粒还在啤酒、鱼类中存在，之前在自来水、软体动物和室内外空气中也都发现了塑料微粒。由此可推断出，现在塑料微粒几乎无处不在。
【高级语块】
micrplastic n. 塑料微粒
sample vt. 取样，尝试，抽样检验
n. 样品，样本
refined adj. 精炼的，精制的
crrelate with 与……相关
ingest vt. 咽下，摄入，食入
