living in cities?2 What are the benefits of vertical farming?3 What do the conditions in space result in?READING FOR LEARNINGFeeding the World 译译文文In the last 60 years,the worlds population has tripled from 2.5 billion in1950 to over 7 billion.Food became a big problem as we were not able to feedeveryone.Now the worlds population is forecast to continue growing andmay hit 11 billion by 2100.So in a world where nearly 1 billion people alreadydo not have enough food,can we really feed another 6 billion?养活全世界养活全世界过去60年，世界人口增长了三倍，从1950年的25亿增长到70多亿。粮食问题已经成为一个大问题，因为我们一直没办法养活所有人。据预测，目前世界人口正持续增长，到2100年，人口数量将达到110亿。所以在世界范围内，已经有近10亿人口没有足够的口粮，我们能否真的再养活60亿人口呢？Feeding the World 译译文文Changing DietsPopulation growth is not the only reason for food shortages.Our diet is also to blame for it.Nowadays,with increasing numbers of people living in cities,we tend to eat more meat.To produce meat we have to use a lot more land and water to grow the food for the animals.And we also need more energy to process the meat.As a result,we are using more land and resources to actually produce less food.We could feed the growing population easily if everyone became a vegetarian.But who would make this change?Would you give up meat to feed others?改变饮食改变饮食人口增长并不是造成粮食短缺的唯一原因。我们的饮食（习惯）也难辞其咎。现在，越来越多的人居住在城市，人们吃肉越来越多。为了生产肉类，我们必须用更多的土地和水，以种植喂养动物的粮食。加工肉类也要消耗更多的能源。结果是，我们使用了更多的土地和资源，却生产出了更少的食物。如果每个人都变成素食者，我们就能轻松养活不断增长的人口。但谁愿意作出这种改变呢？你愿意放弃吃肉来养活别人吗？Feeding the World 译译文文Growing DifferentlyInnovative solutions to this problem are being used and researched aroundthe world.One idea being tried is vertical farming,which is to build farms invery tall buildings in the centre of cities.Such farms require less space.Theyalso reduce the distance the food needs to travel to reach most people.改变种植方式改变种植方式为了解决粮食问题，全世界都在使用和研发创新方案。这种农场占用空间更少，同时还缩短了把食物运送给大多数人的距离。一个正在尝试的理念是垂直农场，即在位于市中心的高楼里建造农场。Feeding the World 译译文文Another innovative idea is the“seeds in space”project organised by the Chinese Academy of Sciences.In 2011,researchers sent seeds into space on the Shenzhou 8 spacecraft.It is thought that the conditions in space help produce huge fruit and vegetables with higher vitamin content.While the science is not yet fullyunderstood,it seems that the conditions in space may help make the seeds more productive.So could space seeds reallyprovide the answer to the worlds food problem?2011年，研究人员通过神舟八号飞船把种子送上太空。虽然人们还未完全掌握这项科学，但似乎太空环境可以使种子更加高产。所以，太空种子真的能解决世界粮食问题吗？另一个创新的理念是由中国科学院组织的“太空种子”项目。人们认为太空环境有助于产出维生素含量更高的巨型水果和蔬菜。Feeding the World 译译文文From sending seeds into space to asking people to change theirdiet,these are all ways of solving the worlds food problem.Whichever methods countries and individuals choose,we still have a long way to go.从发射种子到太空，到改变人们的饮食习惯，这些都是解决世界粮食问题的方法。无论国家和个人选择哪些方法，我们仍任重道远。New Words Phrases and Expressions feedpopulation#tripleforecast growth blame energyprocess#vegetarian innovative solution vertical

VocabularyChinese Academy of Sciences中国科学院Back to VocabularyNow the worlds population is forecast to continue growing and may hit 11 billion by 2100.据预测，目前世界人口正持续增长，到2100年，人口数量将达到110亿。1句中forecast是过去分词表被动。forecast 和forecasted均可作为forecast一词的过去式和过去分词。e.g.Rainwasforecastfortheweekend.预报说周末有雨。Itwasforecastthattheeconomywouldgrowby2%.预测经济将增长2%。So in a world where nearly 1 billion people already do not have enough food,can we really feed another 6 billion?所以，在世界范围内已经有近10亿人口没有足够的口粮，我们能否真的再养活60亿人口呢？2句中where作为关系副词，引导定语从句，修饰先行词world。where引导从句时，用法如下：1)where引导定语从句 where引导定语从句时，其先行词是表示地点的名词，在定语从句中作地点状 语，此时where 相当于at/in/on+which。如：e.g.Thiszooisnottheonlyplacewheretheanimalcanbeseen.这个动物园并不是唯一能够看到这种动物的地方。2)where引导状语从句 where引导状语从句时，相当于in/at the place where。如：e.g.Myfathergrewupwherehewasborn.我父亲是在他出生的地方长大的。3)where引导名词性从句 where引导的名词性从句主要有宾语从句、表语从句、主语从句以及同位语从 句，此时where 相当于the place where。如：e.g.Canyoutellmewhereyoufoundit?你能告诉我你是在哪儿找到它的吗？One idea being tried is vertical farming,which is to build farms in very tall buildings in the centre of cities.一个正在尝试的理念是垂直农场，即在位于市中心的高楼里建造农场。3句中的being tried是现在分词的被动形式，作后置定语修饰名词idea。现在分词的被动形式：being+过去分词，表示其逻辑主语（被修饰的名词等）为现在分词动作的承受者。e.g.正在建的那栋楼是我们的图书馆。Thebuildingbeingbuiltisourlibrary.正在被质问的那栋人是我们的搭档。Thepersonbeingquestionedisourpartner.While the science is not yet fully understood,it seems that the conditions in space may help make the seeds more productive.虽然人们还未完全掌握这项科学，但似乎太空环境可以使种子更加高产。4句中while是连词，引导让步状语从句，意思是“虽然、尽管”，且多放于句首。e.g.Whileheloveshisstudents,heisverystrictwiththem.他虽然爱他的学生，但对他们很严格。句中while也是连词，引导并列状语从句，意思是“而，然而”，且多放于从句之首，引出与主句内容相对比的信息。e.g.Oneofthemlaughedatmewhiletheotherspointedtheirgunsatme.其中一人而其他人So could space seeds really provide the answer to the worlds food problem?所以，太空种子真的能解决世界粮食问题吗？5provide sth to/for sb:“向某人提供某物”，也可用provide sb with sth结构。这两者意思相同，可互换，但介词不可混淆。e.g.Theyprovidedsomenecessarysupportforthesufferers.他们为受难者提供了一些必要的援助。Weprovidelegaladviceandservicestoourclients.我们向客户提供法律建议和服务。Thelectureprovidedhimwithanopportunitytomeetoneofhisheroes.这个讲座能让他见到自己心目中的一位英雄。Whichever methods countries and individuals choose,we still have a long way to go.无论国家和个人选择哪些方法，我们仍任重道远。6whichever 与 no matter which 用法的区别：1)两者都可以引导让步状语从句，表示两者“无论哪个”。e.g.Whichever(Nomatterwhich)dayyoucome,Illbepleasedtoseeyou.无论你哪天来，我都很高兴见到你。2)whichever还可引导名词性从句，但是no matter which不可以。e.g.Whicheverteamgainsthemostpointswins.哪个队得分最多，哪个队就赢。Task 1Read the text quickly.Answer the questions about theeffects of these things.1 What is the effect of more and more people living in
