【语篇解读】服装租赁是新兴的热门行业，零售商希望以此吸引环保消费者。可是，

该行业并不像它看起来的那样绿色环保。它包含的运输环节要比在实体店里买一件衣服然后

在家里洗和穿释放的碳多；清洗环节也会污染环境；而且它可能会使我们更追求快时尚从而

浪费得更多。最环保的做法是穿衣橱里本来就有的衣服。

5.WhatisElizabethCline，sattitudetowardclothingrental?

A.Approving.B.Unfavorable.

C.Objective.D.Enthusiastic.

B［推理判断题。根据第二段第二句可知，Cline得出的结论是，这个行业并不像它看

起来的那样环保；并结合第三至第六段表述的Cline得出这种结论的原因可推知，Cline并

不支持服装租赁，B项意为“不赞成的，否定的，不喜欢的”，故B项正确。C项意为“客

观的”，与文意不符。］

6.TheUberexampleinParagraph6indicatesthat_______.

A.rentalservicesareontherise

B.clothingrentalwillbeassuccessfulasUber

C.rentingclothesmightwastemorethanexpected

D.rentingclothesmightmakepeopleloseinterestinfastfashion

C［推理判断题。根据第六段第二句可知，因为一种产品或服务是共享的，因此就被

认为更环保，但这却使人们浪费得更多。接着下文列举了Uber的例子一一它被宣传为一种

共享出行并限制汽车拥有权的方式，但是最终证明它阻碍了步行、骑自行车和公共交通的使

用，由此可推知，举Uber这个例子表明了服装租赁造成的浪费可能比我们想象的多，故C

项正确。］

7.Theauthorsuggeststhatweshould.

A.giveuprentingclothes

B.purchaseinexpensiveclothes

C.rentclothesratherthanbuythem

D.makefulluseofclotheswe'vepossessed

D［细节理解题。根据尾段尾句“There'sanevenbetterstep—that*swearingwhat

isalreadyinthecloset"可知，作者认为更绿色环保的方法是穿衣橱里己经有的衣服，

故D项正确。］

8.Whatisthepassagemainlyabout?

A.Clothingrentalisanewfashion.

B.Clothingrentalisretailers，preference.

C.Rentingclothesisnotthateco-friendly.

D.Renting-clothesbusinessisinadilemma.

c［主旨大意题。通读全文可知，本文第一段引入话题；第二段提出论点一一服装租

赁业其实并非像它看起来的那样绿色环保；接着第三至第六段给出了论据来支持这一论点；

最后一段作者进行总结并给出建议。由此可知，C项符合文意。］

【语篇解读】本文主要介绍了减少电脑辐射的方法，包括每天喝绿茶、调整电脑屏

幕的亮度、做好皮肤护理、在电脑附近放吸收辐射的植物以及尽可能使用新电脑。

1.F［根据空后一句uGreenteacanbeabsorbedbythebodyeasilyintoaform

ofvitaminA,whichhelpsreduceradiation”可知,绿茶被人体吸收后容易转化为维生

并结合语境可推知，空处应是介绍绿茶的其他好处，故B项与此处匹配。］

3.A［根据空后一句aThebrighterthescreenis,thehighertheradiationwill
