1.WhatdoesthenewStanfordresearchshow?
A.Peoplecandonothingaboutglobalwarming.
B.Theinfluenceofglobaltemperatureriseisincreasing.
C.Peoplecandosomethingtoslowthedeclineforsomecrops.
D.Allcrops'yieldswilldeclineasglobaltemperaturesrise.
答案:
C[解析]根据题干中的thenewStanfordresearchshow定位到原文第一段。
该段中指出，斯坦福大学的新研究显示，欧洲的农场主将看到全球气温升高对农作物产量的影响，但适应变化就能减缓部分作物产量的下降。
由此可知，对于作物产量的下降，人们还是可以采取一些措施使之放缓的，C项表述正确。
A、D两项表述与原文不符，B项表述在原文中并未提及，故选C。
2.Whathappenedtothecropyieldssince1980?
A.Theyieldsofallthecropshavebeendeclining.
B.Theyieldgrowthofsomecropsbecomesslower.
C.Theglobaltemperaturesbecomenotsostableasbefore.
D.Policyandeconomicfactorsbegantoaffectcropyields.
答案:
B[解析]根据题干中的1980定位到原文第二段。
该段第二句中指出，种植这些作物的农场主已经发现，自1980年以来，随着气温的升高，作物产量的增长速度逐渐放缓，尽管其他政策和经济因素对此也有一定影响。
由此可见，B项表述符合原文，故选B。
3.WhatdoesMoorethinkabouttheresultsoftheirresearch?
A.Unexpected.
B.Unbelievable.
C.Alarming.
D.Pessimistic.
答案:
A[解析]根据题干中的Moorethinkabouttheresults定位到原文第四段。
该段首句中指出，穆尔对研究结果略感惊讶，因为欧洲还是相当凉爽的。
四个选项与原文中的surprising“令人感到意外的”意义最为接近的是Unexpected，故选A。
4.Whatcanbecountedas"adaption"accordingtoLobell?
A.Exploringnewtechnologies.
B.Growcropsingreenhouses.
C.Installirrigatingsystems.
D.Releaselessgreenhousegases.
答案:
C[解析]根据题干中的becountedas"adaption"accordingtoLobell定位到原文第五段。
该段首句中罗贝尔说道：
“在我们看来，‘适应’就是以现有技术为基础的一系列措施，如更换作物品种，安装灌溉设施或种植一种完全不同的但能适应较高温度的作物。
”四个选项中符合原文的只有C项，故选C。
5.WhatdoesMooresuggestinthelastparagraph?
A.FarmersinEuropeshouldrespondfastertoclimatesignals.
B.FarmersinEuroperespondwelltoglobalwarming.
C.Thepaceofglobalwarmingcanbesloweddown.
D.Thereisn'tanyavailableoptionforadaptingatpresent.
答案:
A[解析]根据题干定位到原文最后一段。
该段首句中穆尔说到适应变化对于减少这种影响很重要，随后又说道：
“下一个问题是农场主能够在多短的时间内采取可行的适应措施。
欧洲已经变暖了不少，所以如果农场主能够迅速对气候信号做出反应的话，我们可以期待看到他们采取适应措施了。
”由此可见，在穆尔看来，农场主们应该更快地对气候信号做出反应，A项表述正确，故选A。

D.Thosewhositalldaylongandtakeshortbreaksdon'tneedtoworryabouttheirhealth.
答案:
C[解析]推理判断题。
要正确解答此题，需要弄清定位段中That指代的内容。
That不是指代后面的成分，而是指代第一段。
因此可以得知，这里的建议就是第一段的内容。
由此可知C“整天坐着而义担心健康的人应该多一些短暂的休息”为正确答案。
2.Whatcausesthecardiovascularrisk?
A.Keepingcalmforalongtime.
B.Keepingangryforalongtime.
C.Keepingsadforalongtime.
D.Keepingstillforalongtime.
答案:
D[解析]细节辨认题。
由定位句可知，患心血管疾病的风险来自长时间的久坐不动。
故D“长时间不活动”符合题意。
3.WhatisMittleman'sattitudetowardtherecommendationfromtheSurgeonGeneralreport?
A.Hethinkstherecommendationagreeswiththesefindings.
B.Hethinkstherecommendationisopposedtothesefindings.
C.Hethinksindividualsshouldaddexercisesincrementallythroughouttheday.
D.Hethinkspeopleshouldaccepttherecommendation.
答案:
A[解析]推理判断题。
由定位段可知，Mittleman认为报告中提出的建议与研究结果是相符的。
故A“他认为建议与研究结果一致”与文意相符。
4.WhatdidtheteamoftheCancerPreventionResearchCenterdo?
A.TheteamissuedareportwrittenbyHealy.
B.Theteamfoundtheirreportonline.
C.Theteamissuedtheirstudyonline.
D.Theteammadeanonlinejournal.
答案:
C[解析]细节辨认题。
由定位段可知，该小组将研究结果发表在了《欧洲心脏期刊》的网络版上，由此可知，C“这个小组在网上发表了他们的研究成果”符合文意。
5.Whatdowelearnfromthelastparagraph?

D.Peopleshouldexerciseforalongtimeeverydaytokeephealthy.
答案:
B[解析]推理判断题。
定位段第二句指出，研究表明即使个人运动量的细微变化也有可能帮助降低患心血管疾病的风险。
因此推出B“人们应该经常锻炼以降低患心血管病的风险”为正确答案。
