【答案】16.F17.C18.E19.A20.G

【導(dǎo)語】這是一篇說明文。文章主要介紹了一些關(guān)于擁有一個(gè)綠色和開花陽臺(tái)的建議。

16.上文“Balconies（陽臺(tái)）areprobablynotsuitableplacestogrowthings.Theymightbehot,windy,totally

shadyorwithsunlightglaringofftheconcrete.（陽臺(tái)可能不適合種植植物。它們可能很熱，有風(fēng)，完全陰涼，

或者陽光從混凝土上照下來。）“提到了陽臺(tái)惡劣的環(huán)境，不利于種植植物；下文“Herearesometipsforagreen

andfloweringbalcony.（這里有一些關(guān)于綠色和開花陽臺(tái)的建議。）”提到了綠色和開花陽臺(tái)的建議，該空內(nèi)容

與有人成功在陽臺(tái)種植有關(guān)，F(xiàn)選項(xiàng)中managetoplantthem是關(guān)鍵詞，與上文陽臺(tái)的惡劣環(huán)境形成對(duì)比，

且引出下文講陽臺(tái)種植的建議，所以F選項(xiàng)“那么，有些人是如何把它們種在陽臺(tái)上的呢？”具有承上啟下

的作用，符合語境。故選F項(xiàng)。

17.上文“Asmanyexposed（無遮蔽的）sunnybalconiesarealsoverywindy,whichshouldbetakeninto

considerationtoo,avoidthetallerplantsforthosebalconieswherestrongwindsarearegularfeature.（由于許多暴

露在陽光下的陽臺(tái)也有很大的風(fēng)，所以也應(yīng)該考慮到這一點(diǎn)，避免在那些經(jīng)常有強(qiáng)風(fēng)的陽臺(tái)上種植較高的

植物。產(chǎn)提到了在有強(qiáng)風(fēng)的太陽上避免種植較高的植物，C選項(xiàng)“它們會(huì)被風(fēng)吹倒在罐子里”說明了避免種

植較高植物的原因，所以與上文構(gòu)成因果關(guān)系。故選C項(xiàng)。

18.上文“Keepthemmoist（濕潤的），pottedplantsdryoutmuchfaster,evenraindoesn'twetthesoilinmost

potsmuch.（保持濕潤，盆栽植物干得快得多，即使下雨也不會(huì)使大多數(shù)盆栽里的土壤濕潤很多。）”提到了

盆栽里的土壤不太濕潤，E選項(xiàng)“葉子會(huì)把雨水從壺里引出來?！闭f明了土壤不太濕潤的原因，與上文構(gòu)成

因果關(guān)系。故選E項(xiàng)。

19.下文“Allplantsneedtohavetheirleaveswashedatleastonceaweek.Leavesthataren'tregularly

washedgetmite（蜻）problems』所有的植物都需要至少每周洗一次葉子。不經(jīng)常清洗的葉子會(huì)有蜻蟲問題。）”

提到了葉子的清洗，A選項(xiàng)中Clean是關(guān)鍵詞，與下文washed呼應(yīng)，所以A選項(xiàng)“清洗葉子?！蹦芤鹣?/p>

文，符合語境。故選A項(xiàng)。

20.上文“Wellfedplantsarehealthier（喂得好的植物更健康）”提到了健康的植物，選項(xiàng)G中的healthy

是關(guān)鍵詞，與上文healthier呼應(yīng)，所以G選項(xiàng)“它們的根大而健康，能更好地抵御高溫、寒冷和干旱。”能

承接上文，講健康植物的好處，符合語境。故選G項(xiàng)。

【答案】21.G22.D23.A24.C25.F

【導(dǎo)語】本文是一篇說明文。文章介紹了園藝中令人煩惱的雜草問題，提出可以用自然的方法替代除

草劑來除草。

21.前文“Gardensaresomeofthemostbeautifulplacesonearth.Thesadrealityofgardeningisthatweeds

competewiththeplantsyouwantandtakeawayfromtheirbeauty.（花園是地球上最美麗的地方之一。園藝的

悲哀現(xiàn)實(shí)是，雜草與你想要的植物競(jìng)爭(zhēng)，奪去了它們的美麗。戶引入園藝中的雜草問題，后文“Mostpeople

（大多數(shù)人試圖通過使用化學(xué)除草劑來找到一個(gè)快速簡(jiǎn)單的解決雜草問題的方法。）”說明用化學(xué)除草劑解決

雜草問題的方法，G項(xiàng)“Asaresult,weedcontrolseemstobeanever-endingpartofsustainingthebeautyofa

garden”因此，雜草控制似乎是維持花園美麗的一個(gè)永無止境的部分。戶符合語境，說明雜草控制對(duì)于維持

花園美麗的必然性，承接前文雜草問題的結(jié)果，引出后文的解決方法。故選G。

22.前文“Actuallyusingchemicalherbicidescanhavequiteafewunintendedconsequences.（實(shí)際上，使用

化學(xué)除草劑會(huì)產(chǎn)生很多意想不到
