1988年黄石国家公园根据1972年制定的政策允许焚烧森林，但由于风势太大，导致森林大火无法控制，许多动植物都被烧死了，黄石国家公园也不再是热门的游览地。

A.hardtoputout

D.approvedbytheNationalParkService

答案　C

解析　细节理解题。

从第一段的第二句“Itwasacknowledgedthatsomeforestfires,suchasthosecausedbylightningwerenecessaryforforeststomaintainbalancedecosystems,sothefireshouldbeallowedtoburn”可知，选择C项。

2．Whyweresomanyanimalskilledinthebigfire?

B.Becausetheanimalsmovedonlytenmilesaday.

C.Becausetheanimalslivedinlowerplaces.

C.acommercialad

D.ageographymagazine

答案　D

解析　文章出处题。

本文主要讲述的是1988年失控的森林大火给黄石国家公园带来的损害，因此本文与地理风情有关。

故选D项。

B

AllacrossCalifornia,honeybeesareflyingawayfromtheirhives（蜂箱）anddying.Emptyhivesarecausingalotofworryaboutsomeimportantfoodcrops.

蜜蜂除了提供蜂蜜之外，还帮助植物授粉，它们是人类的益友。

但加利福尼亚的大量蜜蜂出现了不明原因的死亡，这引起了人们对重要粮食作物的担忧。

4．WhatisParagraph2mainlyabout?

A.Thewindhelpspollinate.

B.Beesareimportantforfoodcrops.

C.Beesgiveusalotofdelicioushoney.

D.Cherrytreesarepollinatedbybees.

答案　B

解析　段落大意题。

根据第二段的第二、四句可知，蜜蜂可以帮助植物授粉；在美国，养蜂人养的数百万只蜜蜂飞来飞去为粮食作物做着这种重要的授粉工作。

因此选择B。

5．Beesarehardtostudybecause________.

A.theymovearoundtoomuch

B.newbeessoonreplaceallthebeesstudiedbyresearchers

C.theyaretootiny

D.theyneverreturntohives

答案　A

解析　细节理解题。

根据第四段中的“However,beesarehardtostudy.Mostdieawayfromthehive”及Pettis的话“Itisn'tlikestudyingalargeanimallikeacowthatdoesn'tmovearoundmuchandiseasytofindoutinthecowfield”可知，研究蜜蜂很难是因为它们活动得太多。

6．Whatcouldcausesomanybeestodie?

A.Poisonstokillbirds.B.Eatingtoomuch.

C.Largeinsects.D.Somevirus.

答案　D

解析　细节理解题。

根据最后一段中的“Avirusorbacteriacouldalsobedoingthekilling”可知，某种病毒可能是蜜蜂大量死亡的原因，故选D；由最后一段中的“Theycouldbesickbecauseofpoisonswidelyusedtokillinsects”可知，蜜蜂的死亡也可能是由可广泛用来杀死昆虫的毒药引起的，故A项说法不正确。

7．Whatcanwelearnfromthearticle?

A.Alargenumberofbeeshavediedinthehive.

B.Withoutbees,somefoodwoulddisappearfromourdiet.

C.OnlyresearchersinCaliforniawanttoknowwhatkillsbees.

D.Largeanimalsaremoredifficulttostudythantinyinsects.

答案　B

解析　推理判断题。

根据第二、三段可知，某些植物须靠蜜蜂授粉才能结果，由此推知，如果没有蜜蜂给这些植物授粉，那么它们就不会结果，一些食物也就会从我们的饮食中消失了。

故选B。
