A

◎語篇解讀本文為說明文。主題語境為人與自然,主題語境內(nèi)容為人與植物之間的關(guān)系。文

章介紹了綠植對(duì)人類的積極影響和發(fā)光植物的節(jié)能作用并預(yù)測(cè)了其前景。本文有助于培養(yǎng)學(xué)

生的分析、推理、判斷能力以及科學(xué)創(chuàng)新精神。

1.D主旨大意題。本題題干意為:第一段主要講的是什么?根據(jù)第一段第二句（最近的研究發(fā)現(xiàn)

了積極的影響。）以及第三、四句所舉的兩個(gè)實(shí)例（城市中綠化越好的地區(qū)犯罪率越低;裝飾有

室內(nèi)植物的工作場(chǎng)所的員工的生產(chǎn)力提高了15%o）可知,第一段主要講的是綠植帶來的好處。

所以D項(xiàng)正確。A:對(duì)不同植物的一項(xiàng)新研究;B:犯罪率的大幅下降;C:來自不同工作場(chǎng)所的員

?ɑ

2.A細(xì)節(jié)理解題。本題題干意為:麻省理工學(xué)院的工程師們壓印在植物葉子上的傳感器有什

么作用？根據(jù)第二段第二句中的"Theseincludeplantsthathavesensorsprintedontotheirleavesto

showwhenthey,reshortofWater”可知A項(xiàng)（為了檢測(cè)植物缺水）正確。B:為了改變植物的成分;C:

為了讓植物的壽命更長(zhǎng);D:為了探測(cè)植物中的化學(xué)物質(zhì)。

3.C推理判斷題。本題題干意為:我們未來對(duì)這些發(fā)光植物可以有什么期待？由文章最后一句

uGlowingplantscouldreducethisdistanceandthereforehelpsaveenergy.（發(fā)光植物可以縮短距離，

從而有助于節(jié)約能源。）”可知,C項(xiàng)（它們可能有助于減少能源消耗）正確。A:它們將加速能源

生產(chǎn);B:它們可能把電傳輸?shù)郊抑?D:它們可能取代發(fā)電廠。

4.C主旨大意題。本題題干意為:以下哪一個(gè)可以作為這篇文章的最佳標(biāo)題?文章主要講的是

綠植給我們帶來的積極影響并重點(diǎn)講了發(fā)光植物的現(xiàn)狀以及美好前景。結(jié)合文章第三段最后

一句話"Thetechnology,Stranosaid,couldonedaybeusedtolighttheroomsoreventoturntrees

intoself-poweredstreetlamps.（Strano說,這項(xiàng)技術(shù)有一天可以用來照亮房間,或者甚至把樹木變

成自供電的路燈。）”可知C項(xiàng)（CoUIdgIOWingPlantSrePIaCeIamps?）契合文章的核心內(nèi)容。A:我

們可以種植更多的發(fā)光植物嗎?B:我們?nèi)绾闻c發(fā)光植物共同生活?D:如何讓發(fā)光植物無污染？

長(zhǎng)難句

原句Inanother,employeeswereshowntobe15%moreproductivewhentheirworkplaceswere

decoratedwithhouseplants.

分析本句是一個(gè)主從復(fù)合句,主句是"employeeswereshowntobe15%moreproductive,?when

引導(dǎo)時(shí)間狀語從句。

譯文在另一項(xiàng)研究中,當(dāng)員工的工作場(chǎng)所被室內(nèi)植物裝飾時(shí),他們的工作效率顯示了15%的提

◎語篇解讀本文是一篇說明文,主題語境是人與社會(huì),主題語境內(nèi)容為科技發(fā)展。文章介紹了

GeOrgiaTeCh的研究者們想出了一種低成本的裝置——智能鍵盤,來保護(hù)私人的電子空間,并希

望這種設(shè)備能盡快進(jìn)入市場(chǎng),服務(wù)消費(fèi)者。本文側(cè)重培養(yǎng)學(xué)生的創(chuàng)新能力。

5.D細(xì)節(jié)理解題。本題題干意為:研究者們?yōu)槭裁囱邪l(fā)智能鍵盤?根據(jù)文章第一段可知,現(xiàn)在一

些阻止別人進(jìn)入私人電子空間的技術(shù)成本仍然很高。因此,來自GeOrgiaTeCh的研究者們想出

了一種低成本的（1。W-COSt）裝置——智能鍵盤,來應(yīng)對(duì)這個(gè)問題。所以答案為D項(xiàng):減少電子空

間保護(hù)的成本。A:減輕對(duì)按鍵的壓力;B:提升打字的精確度;C:取代密碼系統(tǒng)。

6.C細(xì)節(jié)理解題。本題題干意為:什么使智能鍵盤這項(xiàng)發(fā)明成為可能?根據(jù)第二段第四句

“ThesepatternsareuniquetoeachPerSOn.”可知,因?yàn)槊總€(gè)人的打字模式各不相同,所
