第一单元好好生活 马蒂的故事 你好。我叫马蒂．菲尔丁。我想你可能会说我是“百万人中才有一个”的那种人。换句话说，世界上像我这样的人并不多见。你瞧，我的肌肉有毛病，使我的身体非常虚弱，所以我不能像别人那样快跑或快步爬楼梯。再说，有时候我还会笨手笨脚、不小心摔掉东西，或磕碰到家具上。不幸的是，大夫们不知道如何治好我的病，但是我很开朗乐观，学会了适应身体的残疾。我的座右铭是：活一天算一天。 十岁以前，我跟其他人是一样的。我常常爬树、游泳、踢足球。说实在的，我过去常常梦想我会成为职业球员，代表我们的国家参加世界杯足球赛。后来，我的身体开始变得越来越虚弱，以至于只能坐在体育场的长凳上欣赏足球了。最后我到医院去做了检查，几乎住了三个月的医院。我想我至少做过十亿次检查了，包括有一次检查，他们从我的腿部切下一小块儿肌肉，放在显微镜下观察。即使做过了所有这些检查，也没有人能够确诊这个病。因此，很难知道将来会是个什么样子。 问题是我看上去跟平常人一样。因此，当我跑了很短的一段路之后，我就会喘不过气来，或者爬楼梯才爬到一半就得停下来休息。因此，上小学时有的孩子见了我这种情况就会笑话我。有时候我的身体太虚弱，上不了学，因此落了许多功课。每次缺课之后，我就觉得自己很笨，因为我比别人落后了。 我在中学时期的生活(比在小学时)要轻松多了，因为我的同学开始接受了我的状况。还有些同学看不到我的内心世界，但是我并不生气，只是不去理会他们罢了。总而言之，我生活得挺好。我很高兴我能做许多事情，比如写作和电脑编程。我有雄心壮志，长大后我要在开发电脑软件的公司里工作。去年我发明了一个电脑足球游戏，有一家大公司已经决定从我这儿买走。我的生活很充实，没有时间闲坐着顾影自怜。除了同我的朋友一起去看电影和足球比赛，我还花很多时间和我的宠物在一起。我有两只兔子、一只鹦鹉、一缸金鱼和一只乌龟。我得花大量时间来照顾这些宠物，但我觉得很值。此外，我还有好多功课，特别是在病了一段时间之后。 在许多方面，我身体的残疾倒使我心理上变得更加坚强、更加独立。我必须努力工作才能过上正常的生活，但这是值得的。假如我有机会跟健康孩子讲一句话，那么，这句话就是：身体残疾并不意味着生活不美满。因此，不要感到残疾人可怜，或者取笑他们，也别不理睬他们。要接受他们，给他们以鼓励，让他们能像你一样过得丰富多彩、充实美满。 谢谢你们读我的故事。．马蒂 致建筑师的一封信桑达斯女士 爱丽斯。梅杰 总建筑师剑桥街64号 影院设计公司班克斯敦 希尔街44号 班克斯敦 20(0年9月2,4日 亲爱的桑达斯女士： 今天我从报上了解到，您将成为班克斯敦新影院的建筑设计师。我希望您不介意我写信询问您是否已考虑到残疾顾客的需要。尤其是以下几点不知您是否考虑到了：

Unit 4 THE EARTH IS BECOMIG WARMER-BUT DOES IT MATTER? 全球在变暖——这会带来什么影响吗？ During the 20th century the temperature of the earth rose about one degree Fahrenheit. 在20世纪期间，地球温度大约升了华氏1度。That probably does not seem much to you or me, but it is a rapid increase when compared to other natural changes. 这个数值对你我来说很可能是无所谓的，但是，跟多数自然变化相比较而言，这却是种快速的增长。So how has this come about and does it matter?这种温度的增长是怎么产生的呢，它要紧吗？Earth care’s Sophie Armstrong explores these questions.“关爱地球”组织的索菲·阿姆斯特朗就在探究这些问题。 There is no doubt that the earth is becoming warmer(see Graph 1) and that it is human activity that has caused this global warming rather than a random but natural phenomenon.毫无疑问，地球是在变暖。但是全球变暖的原因是人为的呢，或者仅仅是一种自然现象呢？ All scientists subscribe to the view that the increase i n the earth’s temperature is due to the burning of fossil fuels like coal, natural gas and oil to produce energy. 所有的科学家认为，人们为了生产能量而燃烧化石燃料（如煤、天然气和石油等），从而引起了地球温度的升高。Some byproducts of this process are called “greenhouse” gases, the most important one of which is carbon dioxide.这个升温过程的副产品就叫做“温室”气体，其中最重要的就是二氧化碳。Dr Janice Foster explains: “There is a natural phenomenon that scientists call the “greenhouse effect”. .贾尼丝·福斯特博士解释说：“你知道，有一种科学称之为‘温室效应’的自然现象。This is when small amounts of gases in the atmosphere, like carbon dioxide, methane and water vapour, trap heat from the sun and therefore warm the earth.这种现象发生在大气层中少量的气体（如二氧化碳、甲烷、水蒸气等）吸收太阳的热量，因而，使地球变暖。 Without the‘greenhouse effect ，the earth would be about thirty-three degrees Celsciu cooler than it is. 如果没有这种‘温室效应’，地球的温度将比现在的温度还要低33摄氏度左右。So, we need those gases. 因此，我们需要这些气体。The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere. 而当我们因为燃烧化石燃料而使大气层中增加了大量额外的二氧化碳时，问题就来了。It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up.二氧化碳含量的增加意味着更多的热量被困在大气层中，从而引起了全球温度上升。 We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years. 我们知道，在过去100~150年期间，二氧化碳的含量急剧增加了。It was a scientist called Charles Keeling, who made accurate measurements of the amount of

成功学习英语 早在18世纪人们就预言英语有一天会成为全球性语言，而这一预言在近几十年中已经得到了证实。国际公司的增长和通讯方面的巨大进步带来了学习英语的新潮流。当今世界，要想取得令人瞩目的成就，就要会讲至少两种语言，特别是英语。 然而，没有英语语言环境，学习英语是很难的。一些受人推崇的关于获取语言的理论认为，要达到一种外语水平的流利程度和准确性，你需要置身于这种语言环境之中。但遗憾的是，我们很少有人有机会生活在讲英语的国家，所以大部分人还是得靠学校的语言课程来学习外语。 我国最新颁布的英语教学大纲鼓励老师在教室里创设一种丰富多彩的外语环境。这就意味着，他们要确保通过多种方式给学生足够的英语输入量。足够量的语言输入可以以高质量的阅读和听力材料的形式呈现。不管是说还是写，高质量的输入信息才能保证学生高质量的语言输出。 然而，要取得成功就意味着课后仍需要额外付出。专家认为每天仅仅15分钟的课后学习可以促进外语学习的速度。下面是专家对英语学习的建议： ·制定切实可行的学习目标。例如：为扩大词汇量，每天学10个生词——一周五天——周末复习所学生词。一周学50哥词就意味着一个月可掌握200个词。 ·一周先学一首英语歌曲中的单词，再听几遍这首英语歌曲。 ·先观看母语新闻，然后阅读一份英文报纸或访问一家英文新闻网站。读前能了解主要新闻内容会确保用英语阅读时更透彻地理解所读新闻。 ·观看你最喜爱的一张光盘，但要把你熟悉的部分语言调换成英语。 ·和朋友一道学习，互相测试并分享学习策略——这可以使学习更快乐。 ·赞赏自己。如果你达到了目标，就款待自己。将你的目标告知一个朋友，以使他也能够激励你。 这些建议都很容易做到，也值得付出额外的努力。然而，一天多学那15分钟，的确需要很大的付出。为保持不断努力的势头，你需要时常想想为什么要学英语。理由很简单，在当今世界，英语持有通向更光明的前途和把握未来机遇的钥匙。 肢体语言言为心声 如果你看见一位父亲高兴地笑着并轻轻拍打他儿子的后背，你认为会发生什么？你也许会认为这位父亲正祝贺他的儿子某事做得很好，也许是通过了测试或比赛获胜。因为你明白那位父亲的肢体语言所传达的信息，所以你会知道发生了什么事情。在全球，轻拍后背并附带一个微笑通常意为“干得好”。 每一天全世界不同国籍的人都使用着肢体语言。这是一种没有词语，由手势、面部表情和身体动作组成的语言，它极大地丰富了——有时甚至取 代了——口头语言。同其他任何语言一样，肢体语言被用来交流喜怒等情感和态度，但是与口头语言不同的是，他不总是明确清晰的，所以它又不同于口语。高兴地跳起来的人很容易看到，然而把眉毛往上耸来传达怀疑的态度却更易为人们所忽略。 人们经常有意识地使用肢体语言。不知道一个问题答案的人会先耸起双肩然后让它们落下，

Unit 5 中国学生适应能力强 六个月之前，谢蕾告别了她在中国的家人和朋友，登上了前往伦敦的飞机。这是她第一次离开自己的祖国。课间休息时我在学生餐厅碰见谢蕾，她告诉我的说，“我很激动，因为很久以前就梦想着能有这么一天，但是我又非常紧张，因为我不知道我所期望的是什么。” 谢蕾今年21岁，来我们大学上学，希望获得工商管理证书。大多数外籍学生在进入学位课程学习之前都要学一年预科，而谢蕾已经读完半年了。她非常看重预科课程。她说，“预科课程非常有益。在这儿学习跟在中国学习是相当不同的。你必须事先做好准备，或者在这里，或在中国。” “困难不仅仅是在学习方面，你还必须习惯一种全新的生活方式，在一开始的时候这就会占去你的全部注意力。”她说，“有时候我觉得自己像个小孩似的，我得学习如何使用电话，乘公交车时该怎样付款，在商店买东西时如果不知道商品的英文名字时，又怎样问店主。当我迷路不得不向路人问路时，经常听不懂他们说的话。他们说的话不像我们在听力磁带上听到的那样。”谢蕾说着笑了。 谢蕾同房东一家人住在一起，他们给了她许多建议。虽然有些外国学生同其他同学一起住在学生宿舍或公寓房里，但有些学生选择寄宿在英国人的家中。有的房东家也有上大学的孩子，跟这样的人住在一起会给外国学生提供机会，更好地了解这个国家的日常生活和风俗习惯。“当我听到不理解的话语，或看到似乎有人干了很奇怪的事情时，我就可以向房东家里的人请教。”谢蕾解释说。“还有，当我想家的时候，房东家就是我家的替身，给了我很大的安慰。” 谢蕾的预科课程还帮助她熟悉了西方大学里在学术方面的要求。她对我说，“还记得我交给老师第一篇论文。我在网上找到一篇文章，看来和我所需要的信息恰好一样。于是我就那篇论文写了一篇类似小结性的文章，交给了老师。我原以为我会得到高分，结果只得了一个E。我非常吃惊，于是去找导师说理。”他告诉我说，首先，我不能把别人的话写下来不表示感谢。此外。他认为，别人的想法并不是重要的。他想要知道的是我所想的是什么。这倒把我弄糊涂了，因为该文作者所知道的比我多得多。导师给我解释说，我得阅读大量的、有关不同观点的文章，并进行分析。然后，在我的论文中，我得表明我自己的观点，并且引用别的作者的观点来说明为什么我相信我的观点。起初，我缺乏信心这样做，而现在我开始懂了，我的分数也有所提高了。 谢蕾告诉我说，现在她在英国感到自在多了。开始时认为似乎很怪的事，如今觉得似乎很正常了。“我还有一件事要做，做了这件事后我才得安心。一直忙于适应环境，以至于我没有时间去搞社会活动。我认为在学习和社会生活之间的平衡也是很重要的。我打算参加大学了的几个俱乐部，我希望我会遇到一些有共同爱好的人。” 关于谢蕾的进步，我们将在今后几星期的报纸中做跟踪报道。同时我们衷心祝愿她事业有成。她是应该取得成功的。 Using language 秘鲁

Unit 3 A healthy life Part I Advice from Grandad 爷爷的忠告 Dear James, 1.It is a beautiful day here and I am sitting under the big tree at the end of the garden. I have just returned from a long bike ride to an old castle. It seems amazing that at my age I am still fit enough to cycle 20 km in an afternoon. It’s my birthday in two weeks’ time and I’ll be 82 years old! I think my long and active life must be due to the healthy life I live. 今天这儿的天气很好。现在我正坐在花园尽头的那棵大树底下呢。我刚刚才回来，骑自行车跑了很长一段路，一直到了古城堡。感到惊奇吧，像我这样的年纪，身体健康而且能在一个下午骑车跑20公里。再过两个礼拜就是我82岁的生日了！我想我之所以长寿而且精力充沛，要归功于我的健康生活。 2.This brings me to the real reason for my letter, my dear grandson.

So when the drug leaves your body, you get withdrawal symptoms. I remember feeling bad-tempered and sometimes even in pain. Secondly, you become addicted through habit. As you know, if you do the same thing over and over again, you begin to do it automatically. Lastly, you can become mentally addicted. I believed I was happier and more relaxed after having a cigarette, so I began to think that I could only feel good when I smoked. I was addicted in all three ways, so it was very difficult to quit. But I did finally manage. 这儿我想顺便问你一个问题,你知道上瘾有三个方面的原因吗?首先,你会在身体上对尼古丁有瘾,它是香烟里几百种化学物质之一。这就是说,过一段时间以后,你的身体习惯了香烟里的尼古丁,一旦你的体内没有这种麻醉剂了,你就会有断瘾症状,我记得曾感到烦燥、甚至痛苦。其次你也可能因为习惯的原因而上瘾。你知道,如果你反反复复地做同一件事情,你就会自动地做它。最后,你可以心理
