1.Growingriceunderhighcarbondioxideconditionsmay.

A.increaseironintherice

B.makeitmoredelicious

C.causealossofvitaminE

D.makeitlessnutritious

解析推理判斷題。根據(jù)第二段中的"Ricegrownunderhighcarbondioxideconditions

had,onaverage,13to30percentlowerlevelsoffourBvitaminsand10percentless

protein（蛋白質(zhì)）.Thecropsalsohad8percentlessironand5percentlesszincthan

ricegrownundernormalconditions.可知，在二氧化碳含量高的條件下生長的水稻所含

的營養(yǎng)物質(zhì)比正常情況下生長的水稻少了很多。故D項正確。

2.Howcanpeoplereducethenutritionalharmofclimatechange?

A.ByimportingricefromChinaandJapan.

B.Bytakingotherkindsoffoodinsteadofrice.

C.ByavoidingeatingricefromSoutheastAsia.

D.Bygrowingricesuitablefortheenvironment.

答案|D

解畫細(xì)節(jié)理解題。根據(jù)最后一段的內(nèi)容可知,減少氣候變化對水稻營養(yǎng)破壞的方法是種植一

些能夠適應(yīng)二氧化碳含量較高的氣候條件的水稻品種。故D項正確。

3.What'stheauthoryspurposeofwritingthetext?

A.Toinformreadersofwhatnutrientsfoodcropscontain.

B.Tocallonpeopletocarefortheplanettheyliveon.

C.TosharetheresultsofsomestudiesonpeopleJsdiets.

D.Totellreaderswherefoodcropsaremainlyproduced.

ggB

畫推理判斷題。根據(jù)文章第一段和倒數(shù)第二段可知,在二氧化碳含量高的條件下生長的水

稻、小麥、豌豆、大豆等植物,其營養(yǎng)物質(zhì)都有不同程度的丟失,這些對人類生存產(chǎn)生了威脅，

因此本文是為了提醒人們關(guān)愛我們生活的地球。故B項正確。

4.Inwhichpartofamagazinecanyoureadthetext?

A.Advertisement.B.Artsandculture.

C.Sciencereport.D.Businessnews.

播案|c

畫推理判斷題。本文是一篇說明文,主要說明了溫室氣體可導(dǎo)致農(nóng)作物營養(yǎng)含量降低,這

屬于科學(xué)研究的范圍，與廣告、文化藝術(shù)及商業(yè)新聞無關(guān)，故c項正確。

A.Drinkingcoffeeisthefirstthinginthemorning.

B.Coffeebeans'originmakesallthedifferences.

C.Somepeopleareaddictedtodrinkingcoffee.

D.It'sthesmellofcoffeethatreallymatters.

答案|D

解析細(xì)節(jié)理解題。根據(jù)第一段第二句"Forme,it'sthesmelloffreshlybrewed

coffee.w以及第二段第三句中的“hebelievesthesmellisabsolutelyvitalw可知，

兩人都認(rèn)為咖啡的味道非常重要。故選D項。

6.Whatdoestheauthorcomplainabout?

A.Theprocessofmakingcoffee.

B.Thehightemperatureofcoffee.

C.Thedesignofthepapercoffeecup.

D.Theinconvenienceofbuyingcoffee.

ggc

解洞細(xì)節(jié)理解題。根據(jù)第三段最后一句和第四段第一句中的“youaredrinkingitfrom

somethingthatisdesignedtodeliverthehot1iquiddirectlypastyourtongue,but

preventanysmellcominguptoyournose”可知,紙咖啡杯的設(shè)計令作者不滿。故選C

項。

7.Whatcanreplacetheword“eliminating”underlinedinParagraph4?

A.Creating.B.Removing.

C.Increasing.D.Changing.

解析I詞義猜測題。根據(jù)第四段第一句中的"preventanysmellcominguptoyournose"

并結(jié)合畫線詞所在的句子可推知，該詞的含義與prevent含義相近,故選B項。

8.Whatcanbethebesttitleofthetext?

A.WakeupandSmelltheCoffee

B.TrytoBeaRealLoverofCoffee

C.DrinkCoffeetoSavethePlanet

D.ChooseTakeawayCoffeeforConvenience

S]A

解析主旨大意題。根據(jù)第一段第二句"Forme,it'sthesmelloffreshlybrewed

coffee."并結(jié)合文章其他內(nèi)容可知，全文圍繞咖啡的味道展開敘述，主要講述了作者對咖啡

味道的喜愛,并表述了用紙杯裝咖啡的壞處，故A項最適合作本文標(biāo)題。

2.Whatdoestheunderlinedword“it”inParagraph2referto?

A.Theatmosphere.B.Theidea.

C.Theearth.D.Theearthystemperature.

麗代詞指代題。根據(jù)第二段可知,Fourier的結(jié)論是,大氣層負(fù)責(zé)吸收來自太陽的熱量，

并將其描述為一個有玻璃蓋子的盒子：當(dāng)光線穿過玻璃時，內(nèi)部溫度會隨著蓋子吸收熱量而

升高。由此可知此處it指的是大氣層。故選A項。
