专题限时训练（二十七）

（一）【篇章导读】本篇是一篇说明文。

主要介绍了将原用于军事和卫星的红外线扫描技术应用于农业的前景，人们为此所做出的努力及遇到的困难。

1．C　细节理解题。

依据文章第二段“...aninfraredscannermeasuredtheheatemittedbycrops.Thedataweretransformedintoacolorcodedmapshowingwhereplantswererunning‘fevers’”可知，植物“身体状况”不佳（发烧）时才会散发热，所以选项C符合题意。

2．D　推理判断题。

本题要求判断使用红外线扫描技术的方式。

依据文章第二段“...showingwhereplantswererunning‘fevers’．Farmerscouldthenspotspray，…”说明目的是确定有问题的区域，以使农民有针对性地喷杀虫剂。

显然，选项D（确定有问题的地域）为最佳选项。

3．A　细节理解题。

依据文章第二段最后一句“Farmerscouldthenspotspray,using50to70percentlesspesticidethantheyotherwisewould”（采取点喷，农民可以节省平时用量的50%至70%的杀虫剂），选项A符合题意。

4．C　推理判断题。

依据文章第三段的第一句“ThebadnewsisthatPaley'scompanycloseddownin1984,afteronlythreeyears.Farmersresistedthenewtechnologyandlongtermbackerswerehardtofind”，可以看出红外线扫描技术应用于农业遇到了一些问题，原因有两个：

一是农民对新技术的抵制，二是难以找到长期赞助商。

文章中还有一处明显的提示出现在最后一句：

“ButonlyifPaleyfindsthefinancialbackingwhichhefailedtoobtain10yearsago”．从该句提供的信息同样可以反推出10年前的情形，所以选项C正确。

5．B　细节理解题。

依据文章第三段“Butwiththerenewedconcernaboutpesticidesonproduce,andrefinementsininfraredscanning，Paleyhopestogetbackintooperation.”可知B项（出于对杀虫剂过度使用的担心）符合题意。

（二）【文章大意】本文为说明文，主要介绍威尼斯引以为豪的古建筑正承受着来自人类与大自然的双重威胁。

1．D　逻辑推理题。

根据第一段“butinVeniceverynearlyeverythingisremarkable,fromthemagnificentPiazzaSanMarco（St.Mark'sSquare）andthepalacesthatlinetheGrandCanaltothecenturiesoldhomesofsimplefishermen.”可判断威尼斯以它杰出的古建筑而闻名，故选D。

2．A　细节理解题。

根据第一段“Itwouldbeeasytosaythatthecityitselfisanenormousmuseumifitwerenotforthefactitissoobviouslyalive.”可推断作者认为威尼斯是巨大的博物馆，故选A。

3．A　细节理解题。

根据第三段“...thewashproducedbytheconstantlyincreasingnumberofmotorboatsthatspeedupanddownthecanals.”可判断选A。

4．D　细节理解题。

根据第四段“AfurtherthreattoVenicecomesfromtheVenetiansthemselves...”可知人为因素比自然因素对威
