Dgs are ur best friends. That’s especially true after a disaster，such as an earthquake. When buildings fall dwn，search-and-rescue dgs help find trapped peple. Dgs’amazing nses can pick up the smell f survivrs. Nw scientists have develped electrnic tl that des the same thing. It’s taking smell detectin（探测）t a whle new level.
The new inventin is a srt f electrnic nse, which can detect extremely lw levels f many cmpunds（化合物）frm peple’s skin. This isn’t the first time engineers have develped such an bject. Earlier mdels，hwever，have been bulky and expensive. They culd nt detect lw levels f target cmpunds either. The new ne is inexpensive and small enugh t fit inside hand-held equipment.
The electrnic nse can detect extremely slight smell f mre than ne cmpund at the same time.“Being able t d this，in such a small bject，is the significant discvery，”says Stiris E. Pratsinis，Prfessr f Prcess Engineering and Materials Science at the Swiss Federal Institute f Technlgy in Zurich. His team tested it in special spaces. They were like the small spaces where peple might be trapped. Chemicals given ff by the vlunteers built up inside. The electrnic equipment detected thse cmpunds at unbelievably lw levels.
The results were gd news fr the research team. But they may be nt fr ur fur-legged friends，wh culd sn be ut f a jb.“Ideally，this technlgy culd replace search-and-rescue dgs,”Pratsinis says.
Stephen Taylr, an electrical engineer, agrees that the new technlgy has sme benefits ver dgs. Still, he thinks it may be t sn t have ur trusty friends retire. He suspects,“I fresee that such an bject culd add t the fine wrk dne by the dgs.” Taylr als pints ut sme ptential limitatins f the new inventin.“E-nses are useful, but can be very likely t be affected by unstable readings and interruptin,”he says.
1. Why des the authr talk abut dgs at the beginning?
A. T catch the readers’ attentin.
B. T intrduce the tpic abut e-nses.
C. T shw what search-and-rescue dgs d.
D. T add backgrund infrmatin fr discussin.
2. Which f the fllwing best explains“bulky”underlined in Paragraph 2?
A Cmplex. B. fragile. C. Handy. D. Large.
3. What is Paragraph 3 mainly abut?
A. What e-nses’ wrking principle is.
B. Hw e-nses are made.
C. What differences between dgs and e-nses are.
D. Hw pwerful e-nses are.
4. What des Stephen Taylr mean？
A. Dgs and e-nses culd wrk tgether.
B. Search-and-rescue dgs will retire sn.
C. E-nses are mre reliable than nses f dgs.
D. Dgs are better at finding ut trapped peple.

Imagine an area 34 times the size f Manhattan. Nw imagine it cvered ankle-deep in plastic waste—a ttal f abut 19 billin punds f garbage. 1
“We’re being verwhelmed（淹没）by ur waste，”said Jenna Jambeck，an envirnmental engineer wh led the 2015 study that determined this astnishing number. 2 , unless smething is dne t stp the tide f garbage.
Plastic—a widely-used material—has in many ways been a benefit t humans but it has als caused a grwing prblem. Tday，plastics are the N.1 type f garbage fund in the sea. Ocean Cnservancy，a nn-prfit envirnmental advcacy grup that rganises an annual castal cleanup event wrldwide，said plastic waste makes up arund 85 per cent f the garbage cllected frm beaches and ceans.
Oceans Cnservancy says plastics are believed t threaten（威胁）at least 600 different wildlife species（物种）. 3 ；a grwing bdy f evidence suggests humans are cnsuming plastics thrugh the seafd we eat. Research suggests sme plastics culd be pisnus t humans, and culd ptentially increase the risk f health prblems.
4 . At the Ecnmist Wrld Ocean Summit this week, ten natins annunced t reduce plastic sea litter as part f UN Envirnment’s Clean Seas campaign. 5 . Crpratins als have a rle, as d individuals. We can start by thinking twice befre using single-use plastic prducts—and when we d use them, we shuld take care t prperly thrw them ff r recycle.
A. The fllwing is what we shuld d
B. And it’s nt just wildlife that’s threatened
C. And this figure is likely t duble by 2025
D. But it’s nt just cuntries that need t d their part
E. By 2050, that figure is expected t rise t 1,000 pieces
F. That’s hw much plastic waste ends up in ur ceans every year
G. All f us have an imprtant rle t play in dealing with the prblems
答案解析

【语篇导读】这是一篇说明文，介绍了一种可以用于探测的电子鼻。
1. B 推理判断题。第一段中，作者先介绍了狗的鼻子有很多用途，然后介绍科学家现在发明了可以做同样事情的电子鼻。由此可以推断，先提及狗是为了引出电子鼻的话题，故选B项。
2. D 词义猜测题。根据第二段中的 Earlier mdels，hwever，have been bulky and expensive…The new ne is inexpensive and small enugh t fit inside hand-held equipment.可知，早期的电子鼻比较昂贵且“bulky”，新型的电子鼻则体积小巧，可放入手持设备内，新旧形成对比，由此猜测 bulky是“庞大”的意思，故选D项。cmplex意为“复杂的”，fragile意为“易碎的”，handy意为“方便的”。
3. D 主旨大意题。第三段主要介绍了电子鼻可以同时检测到多种化合物极其轻微的气味，故选D项。
4. A 推理判断题。根据最后一段中的“I fresee that such an bject culd add t the fine wrk dne by the dgs.”可知，斯蒂芬·泰勒认为电子鼻可以配合狗进行工作，故选A项。

【语篇导读】本文属于议论文，介绍塑料垃圾问题越发严重，不但威胁野生动物，还影响人类自己，需要全世界通力合作来应对。
1. F 根据前一句 Nw imagine it cvered ankle-deep in plastic waste-a ttal f abut 19 billin punds f garbage.可知，塑料垃圾总共为190亿磅左右，F选项“这就是每年被丢到海洋里的塑料垃圾的数量”与前文呼应，故选F项。
2. C 根据后文 unless smething is dne t stp the tide f garbage（除非采取一些措施来减少垃圾）可知，C选项“预计到2025年，这个数字很可能会翻倍”与后文形成条件关系，切题，故选C项。
3. B 根据后文 a grwing bdy f evidence suggests humans are cnsuming plastics thrugh the seafd we eat可知，越来越多的证据显示人类通过食用海产品也摄入了塑料，B选项 “不仅野生生物受到威胁”切题，故选B项。
4. G 根据本段后文 ten natins以及 Crpratins可知，这个问题需要全世界共同合作，G选项“所有人都能够为解决此问题发挥重要作用”切题，故选G项。
5. D 根据下一句 Crpratins als have a rle，as d individuals.可知，企业和个人也能发挥作用，D选项 “不仅仅是国家需要尽到责任”引出下文，切题，故选D项。
长难句分析 Research suggests sme plastics culd be pisnus t humans，and culd ptentially increase the risk f health prblems.
句式分析：本句为复合句，Research为主句的主语，suggests为主句的谓语，sme plastics culd be pisnus t humans…是省略了that的宾语从句。
句意：研究表明，一些塑料可能对人类有毒，并可能增加健康问题的风险。
