险警报。

4.Whatdoestheunderlinedphraseinthefirstparagraphmean?

A.Defendagainst.B.Feed.

C.Hidefrom.D.Attract.

选A。短语猜测题。由文章第一段可知黑犀牛的视力很差。它们的基

本身体结构已被证明是足够好的，可以在到处都是大型食肉动物的

鸟经常悬挂在犀牛的背上，以寄生虫为食。及第三段中第一句可知,

这些鸟也通过啃食犀牛身上的伤口来获取营养。可推知，牛棕鸟在犀

牛背上的原因是：可以获得食物(findfood)。故选C项。

6.Whatdotheresearchersfind?

A.Rhinoshavepooreyesight.

B.Thebirdsalarmandrhinoslisten.

C.Therearemanyticksonrhinos.

D.Thebirdshavesharpeyes.

Bo

鸟的警报声。可推知，研究结果为牛棕鸟确实可以发出警报声，而犀

牛也听到了,B项正确。A项称，黑犀牛视力差。这句话虽然正确，但

是不是这次的研究发现,A项错误;C项和D项也是同样的错误。故选

B项。

7.Whatcanbestdescribetherelationshipbetweenthebirdsand

rhinos?

A.Theyprotecteachotherfromdangers.

B.Theyarefoodsourceforeachother.

C.Theydependoneachotherforsurvival.

的鸟经常悬挂在犀牛的背上，以寄生虫为食。及第三段第一句可知这

些鸟也通过啃食犀牛身上的伤口来获取营养。可推知，红嘴牛棕鸟可

以在犀牛身上获取食物，而由最后一段最后一句"毫无疑问，犀牛正

在听牛棕鸟的警报声。〃可知，红嘴牛棕鸟也可以给犀牛发出警报。

因此两者之间是双赢的(win-win)关系。故选D项。

不仅对我们的健康有害，同时对环境也造成了影响。作者呼吁人们购

买质量好的衣物，捐赠旧衣服等，为环保做出自己的努力。

继续购买，只是为了能够跟上潮流。）与C项Trendsarechangingso

跟不上。）承接自然，因为潮流改变很快，所以只能通过不停购买来跟

上。选项中的trends呼应下文的uptodateo故选Co

3.选A。由上文可知此外，用于纺织生产各个部分的化学物质都非常

有害。甚至100%纯天然纤维制成的衣服仍然有大量的化学物质。与

A项Theycanpresentarealdangertoourhealth.（他们给我们的健康带

来了真正的危险。）承接自然，纺织生产的各个部分都添加了有害的化

学物质，他们给我们的健康带来危险。选项中的they就指代上文的

chemicalSo故选A。

4.选Bo上文“Clothinghasclearlybecomedisposable."（彳艮明显，衣服

已经变成一次性的了。）与B项Asaresult,wegeneratemoreand

moretextilewaste.（因此我们产生了越来越多的纺织垃圾。）承接自

然，上下文构成明显的因果关系。因为衣服成为一次性的，所以会产

生越来越多的纺织垃圾。故选B。

5.选Fo由上文可知我们如何避免时尚产业对环境的影响与F项To

achievethegoalweshouldfirstreflectonourlifestyleandbuyless.（为

了实现这个目标，我们首先应该反思我们的生活方式，少购买衣服。）
