塞罕坝位于中国北部的河北省，是世界上最大的人造林，面积达76700公顷（大约115万亩）。它已成为国家级森林公园，也是北京及周边地区重要的生态屏障。20世纪50年代末之前，因为过度砍伐，塞罕坝成了一片荒山野岭。大风夹带着沙尘从春天吹到冬天。因此，北京经常遭到沙尘暴袭击。

为了改变这种状况，原林业部决定在塞罕坝建造林场。1962年，来自全国各地的369人，即第一代塞罕坝林木工人，被派往那里种树。然而，他们发现，由于自然条件恶劣，在那种树很艰难。开始只有大约8%的树能存活。后来随着新技术的应用和艰辛的劳作，小树的存活率提高到了98%。TextA译文Unit3自从20世纪60年代早期以来，三代塞罕坝护林人已经把这一地区的森林覆盖率从11.4%提高到了98%。据报道，现在塞罕坝广阔的森林每年能吸收860,300吨二氧化碳并释放598400吨氧气。由于其杰出的贡献，2017年，塞罕坝被联合国环境规划署授予了最高荣誉——地球卫士奖。

塞罕坝的发展是林业工人坚持不懈努力的结果。它为中国追求生态文明建设树立了伟大的典范。TextA译文Unit3Itistheworld’slargestman-madeforest,whichcoversabout76,700hectares(about1.15millionmu).塞罕坝是世界上最大的人造林，面积达76700公顷（约合115万亩）。句中，which引导非限制性定语从句，其先行词是theworld’slargestman-madeforest。NotesUnit3formerMinistryofForestry原林业部NotesUnit3Itisreportedthat…据报道，……NotesUnit3ChampionsoftheEarthAward地球卫士奖NotesUnit3theUnitedNationsEnvironmentProgram联合国环境规划署NotesUnit3TextB译文Unit3拯救鲨鱼

许多人认为鲨鱼是危险的巨兽。但是，人类对鲨鱼的伤害远远大于鲨鱼对我们的伤害。虽然出现过鲨鱼对人类的攻击，但是很罕见。相反，据估计每年人类杀死一亿头鲨鱼。这个统计数据警示我们许多种类的鲨鱼正在灭绝。所以，许多环保人士呼吁拯救鲨鱼。

我们为什么要拯救鲨鱼？最重要的原因是杀戮鲨鱼是全球的问题。鲨鱼吃许多动物，但没什么动物吃鲨鱼。当鲨鱼相继死去时，它吃的动物的数量就会增长。相应地，这就意味着那些动物吃的生物的数量就会减少。其中就包括人类食用的海洋生物，比如虾。TextB译文Unit3也包括吃藻类的鱼。那些鱼类的减少可能会导致藻类大量繁殖，以致破坏珊瑚礁。生态系统将会大受影响。那么，我们能如何来帮助拯救鲨鱼呢？首先，不要用鲨鱼产品，比如，功能饮料和皮革产品。所有这些产品都有可能是由鲨鱼制成的。第二，只吃养殖海鲜。当你吃海鲜的时候，一定要确保它来自爱护海洋的渔场。NotesUnit3Buthumansaredoingmoreharmtothemthantheydotous.但是，人类对鲨鱼的伤害要比它们对我们人类的伤害更大。NotesUnit3…,butfewcreatureseatthem.……但是几乎没有动物能吃他们。few：不多，很少，几乎没有，与复数名词和复数动词连用。NotesUnit3Thedecreaseofthosefishcancausealgaetospreadsomuchthatitdamagesthecoralreefs.那些鱼类的减少可能会导致藻类大量繁殖，以致破坏珊瑚礁。句中so…that…引导结果状语从句，表示“如此……以至于……”。13UNITProtectionofEnvironment高职英语综合教程TheEnd1高职英语综合教程Unit414UNITPublicWelfare高职英语综合教程Totalkaboutpublicwelfare;ToreadabouttheInternet-basedcharityandvolunteerteaching;Topronounceconsonants“[ʃ],[ʒ],[θ],[ð],[m],[n],[ŋ]”;Tocorrectlyusethepresent,pastandfutureprogressivetenses;ObjectivesTowritelettersofthanks.Tolistenandgetinformationaboutpublicwelfare;ListeningandSpeakingContentsTextATextB
