答案　D

Afterreadingthepassage，pleasefillinthefollowingblanks.

Thereisnodoubt1.thattheearthisbecomingwarmerandthat2.itishumanactivitythathascausedthisglobalwarming.

ManyscientistslikeDrJaniceFosterbelievethatpeoplehavecausedtheincreaseintheearth’stemperatureby3.burning（burn）fossilfuelslikecoal，naturalgasandoiltoproduceenergywhosebyproducts4.arecalled（call）“greenhouse”gases，themostimportantone5.being（be）carbondioxide.Thesegasestrapheatfromthesunandthereforewarmtheearth，without6.whichtheearthwouldbeaboutthirtythreedegreesCelsius7.cooler（cool）thanitis.Butincreasedamountofextracarbondioxidemeansthatmoreheatenergyistrappedintheatmosphere8.causing（cause）theglobaltemperaturetogoup.

1．Thereisnodoubtthattheearthisbecomingwarmer（seeGraph1）andthatitishumanactivitythathascausedthisglobalwarmingratherthanarandombutnaturalphenomenon.

[句式分析]　本句中Thereisnodoubt后接了两个that引导的并列的同位语从句；

第二个同位语从句中itishumanactivitythat...phenomenon是一个强调句，强调了主语humanactivity。

[自主翻译]　毫无疑问，地球正变得更加暖和（见图表1），并且全球变暖是人类活动造成的，而不是随意的自然现象。

2．Itmeansthatmoreheatenergytendstobetrappedintheatmospherecausingtheglobaltemperaturetogoup.

[句式分析]　本句是一个复合句。

that引导一个宾语从句；

causingtheglobaltemperaturetogoup为现在分词短语作结果状语。

[自主翻译]　它意味着更多的热能将被困在大气层中，从而引起全球气温上升。

3．Ontheotherhand，therearethose，likeGeorgeHambley，whoareopposedtothisviewandbelievethatweshouldnotworryabouthighlevelsofcarbondioxideintheair.

therearethose，likeGeorgeHambley是主句。

whoareopposedtothisviewandbelievethatweshouldnotworryabouthighlevelsofcarbondioxideintheair为who引导的定语从句。

该定语从句又分为两部分，由and连接。

areopposedtothisview为一部分；

believethatweshouldnotworryabouthighlevelsofcarbondioxideintheair为另一部分，其中含有一个that引导的宾语从句。

[自主翻译]　另一方面，有一些科学家，像乔治·

汉布利，反对这种观点，他们认为我们不必担心空气中高含量的二氧化碳。

1．Thetextismainlyabout.

A．rapidchangesintheearth’stemperature

B．badeffectsofglobalwarming

C．movingofacountrytoanewplace

D．reasonsforlowlandflooding

解析　主旨大意题。

这篇短文主要讲述了全球变暖造成的恶劣影响。

2．Accordingtoscientists，theDIRECTcauseofmoreandfiercerstormsis.

A．greenhousegasemissionsinindustrializednations

B．highersurfacewatertemperaturesofthesea

C．continuousglobalwarming

D．risingsealevels

解析　推理判断题。

根据第三段中的“Manyscientistsconnecthighersurfacewatertemperaturesresultingfromglobalwarmingtogreaterandmoredamagingstorms.”可以推断出一些科学家认为造成严重的暴风雨的直接原因是海洋表面水温升高。

3．LaupepawasnotsatisfiedwiththeUnitedStatesbecauseitdidnot.

A．agreetoreduceitsgreenhousegasemissions

B．signanagreementwithTuvalu

C．allowTuvaluanstomovetotheUS

D．believetheproblemsfacingTuvaluwerereal

根据第四段第一句话可知，Laupepa对美国不满意的原因是美国拒绝签署减少导致温室效应气体排放的国际公约。

4．ThecountrywhosesituationissimilartothatofTuvaluis.

A．AustraliaB．NewZealand

C．theMaldivesD．theUnitedStates

根据最后一段可推断出马尔代夫（theMaldives）与图瓦卢的情况相似。
