Unit4Globalwarming温室效应自地球形成以来，它就一直在起作用。如果没有温室效应，地球表面就会寒冷无比，温度就会降到零下20摄氏度，海洋就会结冰，生命就不会形成。因此，我们面临的不是有没有温室效应的问题，而是大量污染的气体排入大气层，致使温室效应与地球气候发生急剧变化的问题。参考词汇：温室效应greenhouseeffect;零下20摄氏度minus20degreesCelsius【写作要求】只能用5个句子表达全部内容。ThegreenhouseeffecthascomeintobeingsincetheEarthwasformed.Withoutit,theEarth'ssurfacewouldbeextremelycoldandthetemperaturewillbedroppedtominus20degreesCelsius.Besides,theoceanwillbeturnedtoice,andnolivingthingscansurviveandexist.Therefore,wearenotfacedwiththegreenhouseeffect,butalargeamountofpollutedgasesintotheatmosphere,causingthegreenhouseeffectandtheEarth'sclimatechanged.Thatiswhyweshouldtakeintoconsiderationtheseriousglobalwarming.1.vt.消费；消耗；耗尽；吃完2.n.现象3.vi.同意；捐赠vt.签署(文件)；捐赠4.n.数量；量5.vi.趋向；易于vt.照顾；护理6.n.趋势；倾向；走向________________________________________________________________________________________________________________________consumephenomenonsubscribequantitytendtrend7.vt.反对；反抗8.n.结果；后果；影响9.vt.陈述；说明10.n.种类；范围11.vi.看一下n.一瞥12.adj.持续的；稳固的13.n.倾向；趋势____________________________________________________________________________________________________________________________________________opposeconsequencestaterangeglancesteadytendency14.adj.分布广的；普遍的15.adj.平均的16.vt.拥护；提倡；主张17.adj.随便的；漫不经心的；偶然的18.n.环境；情况19.vt.使恢复；使振作20.n.分歧；不一致_______________________________________________________________________________________________________________________________________widespreadaverageadvocatecasualcircumstancerefreshdisagreement1.发生；造成2.导致3.忍受；容忍4.等等5.大量的6.继续7.大体上；基本上____________________________________________________________________________________________________________________________________________comeaboutresultinputupwithandsoonquantityofkeepononthewhole8.同意；赞同；订购9.上升；增长；升起10.反对……11.即使12.代表……一方；作为……的发言人13.只要________________________________________________________________________________________________________________________subscribetogoupbeopposedtoevenifonbehalfofsolongas1.Thereisnodoubtthattheearthisbecomingwarmerandthat________humanactivity________hascausedthisglobalwarmingratherthanarandombutnaturalphenomenon.2.Withoutthe‘greenhouseeffect’，theearth________(be)aboutthirtythreedegreesCelsiuscoolerthanitis.itisthatwouldbe3.Theyalsoagreethat________theburningofmoreandmorefossilfuels________hasresultedinthisincreaseincarbondioxide.4.Getyourparents________(buy)thingsthatareeconomicalwithenergy…itistobuythat1.quantityn.量，数量(修饰可数和不可数名词)Hecollectedaquantityofcuriousinformation.他搜集了大量稀奇古怪的消息。注意：当quantitiesof＋不可数名词作主语时，谓语用复数。Largequantitiesofinformationhavebeencollected.大量的信息已被收集。alargequantityof＝largequantitiesof许多inquantity大量地根据汉语意思，完成英文句子(1)他的画家名声靠的是质量而不是数量。Hisreputationasapainterdependsmoreonqualitythan____________________.(2)这家旅馆每天购买大量的肉。Thishotelbuys____________________ofmeateveryday.quantityalargequantity(3)大批量购货较便宜。It'scheapertobuygoods______________________________.inquantity2....
