21、are able to undergo photosynthesis,they do not depend on other organisms for energy.,（二）专业英语语法特点：,41,（1）长句多（可使句意表达严谨）Biology is such a broad field,covering the minute chemical reactions inside our cells,to broad scale concepts of ecosystems and global climate change.,42,英语长句的分析,造成长句的原因,1、修饰语过多,2、并列成

22、分多,3、语言结构层次多,43,分析方法,6、注意分析句子中是否有固定词组或固定搭配。,1、找出全句的主语、谓语和宾语，从整体上把握句子的结构。,2、找出句中所有的谓语结构、非谓语动词、介词短语和从句的引导词。,3、分析从句和短语的功能，例如，是否为主语从句，宾语从句，表语从句等。若是状语，它是表示时间、原因、结果、还是表示条件等等。,4、分析词、短语和从句之间的相互关系，例如，定语从句所修饰的先行词是哪一个等。,5、注意插入语等其他成分。,44,例1.Behaviorists suggest that the child who is raised in an environment whe

23、re there are many stimuli which develop his or her capacity for appropriate responses will experience greater intellectual development.,行为主义者认为，如果儿童的成长环境里有许多刺激因素，这些因素又有利于其适当反应能力的发展，那么，儿童的智力就会发展到较高的水平。,45,例2.For a family of four,for example,it is more convenient as well as cheaper to sit comfortably

24、at home,with almost unlimited entertainment available,than to go out in search of amusement elsewhere.,譬如，对于一个四口之家来说，舒舒服服地在家中看电视，就能看到几乎数不清的娱乐节目，这比到外面别的地方去消遣又便宜又方便。,46,长句的翻译方法,1、顺序法。当英语长句的内容的叙述层次与汉语基本一致时，可以按照英语原文的顺序翻译成汉语。,47,例1.Even when we turn off the beside lamp and are fast asleep，electricity is

25、working for us，driving our refrigerators，heating our water，or keeping our rooms air-conditioned.,即使在我们关掉了床头灯深深地进入梦乡时，电仍在为我们工作：帮我们开动电冰箱，把水加热，或使室内空调机继续运转。,48,例2.But now it is realized that supplies of some of them are limited,and it is even possible to give a reasonable estimate of their“expectation o

26、f life”,the time it will take to exhaust all known sources and reserves of these materials.,可是现在人们意识到，其中有些矿物质的蕴藏量是有限的，人们甚至还可以比较合理的估计出这些矿物质“可望存在多少年”，也就是说，经过若干年后，这些矿物的全部已知矿源和储量将消耗殆尽。,49,2、逆序法。英语有些长句的表达次序与汉语表达习惯不同,甚至完全相反,这时必须从原文后面开始翻译。,50,例1.Aluminum remained unknown until the nineteenth century,becaus

27、e nowhere in nature is it found free,owing to its always being combined with other elements,most commonly with oxygen,for which it has a strong affinity.,铝总是跟其他元素结合在一起，最普遍的是跟氧结合；因为铝跟氧有很强的亲和力，由于这个原因，在自然界找不到游离状态的铝。所以，铝直到19世纪才被人发现。,51,例2.It therefore becomes more and more important that,if students are

28、 not to waste their opportunities,there will have to be much more detailed information about courses and more advice.,因此，如果要使学生充分利用他们(上大学)的机会，就得为他们提供大量关于课程的更为详尽的信息，作更多的指导。这个问题显得越来越重要了。,52,3、分句法。有时英语长句中主语或主句与修饰词的关系并不十分密切，翻译时可以按照汉语多用短句的习惯，把长句的从句或短语化成句子，分开来叙述,为了使语意连贯，有时需要适当增加词语。,53,例1.The number of the

29、 young people in the United States who cant read is incredible about one in four.,大约有1/4的美国青年人没有阅读能力，这简直令人难以置信。,54,例2.Television,it is often said,keeps one informed about current events,allow one to follow the latest developments in science and politics,and offers an endless series of programmes whi

30、ch are both instructive and entertaining.,人们常说，通过电视可以了解时事，掌握科学和政治的最新动态。从电视里还可以看到层出不穷、既有教育意义又有娱乐性的新节目。,55,4、综合法。上面我们讲述了英语长句的逆序法、顺序法和分句法，事实上，在翻译一个英语长句时，并不只是单纯地使用一种翻译方法，而是要求我们把各种方法综合使用，这在我们上面所举的例子中也有所体现。尤其是在一些情况下，一些英语长句单纯采用上述任何一种方法都不方便，这就需要我们的仔细分析，或按照时间的先后，或按照逻辑顺序，顺逆结合，主次分明地对全句进行综合处理，以便把英语原文翻译成通顺忠实的汉语句

31、子。,56,例1.People were afraid to leave their houses,for although the police had been ordered to stand by in case of emergency,they were just as confused and helpless as anybody else.,尽管警察已接到命令,要作好准备以应付紧急情况,但人们不敢出门,因为警察也和其他人一样不知所措和无能为力。,57,例2.Taking his cue from Ibsens A Dolls House,in which the heroin

32、e,Nora,leaves home because she resents her husbands treating her like a child,the writer Lu Xun warned that Nora would need money to support herself;she must have economic rights to survive.,易卜生的剧作玩偶之家中的女主人公娜拉离家出走，因为她憎恶她的丈夫像对待孩子一样来对待她。作家鲁迅从中得到启示，从而告诫人们娜拉得需要钱来养活自己，她要生存就必须有经济上的权利。,58,（2）被动语态使用频繁（描述客观）

33、；,It has been found experimentally that the ratio of the amounts of adenine(腺嘌呤）to thymine（胸腺嘧啶）,and the ratio of guanine（鸟嘌呤）to cytosine（胞嘧啶）,are always very close to unity for deoxyribose nucleic acid（DNA）,59,（3）名词性词组多；分词使用频繁；介词短语多（可使语言精练）；Gene therapy involves the repair or correction of the mach

34、inery。基因治疗包括遗传系统的修复或纠正（4）专业术语多；缩略词多；合成词多；插图，表格，公式，数字所占比例大。,60,三、生物学专业英语的内容,(1)掌握构词法（派生，转换，合成），扩大词汇量。(2)阅读英文原始文献资料，扩大知识面，掌握生物学专业英语的语言规律，提高阅读，写作，翻译水平以及实际应用生物学专业英语的能力。(3)巩固英语基础知识，提高应用英语的能力（大学英语教学大纲要求大学生修完大学英语基础课程后必须学习专业英语。）,61,四、生物学专业英语的学习方法,（1）识记专业词汇，扩大阅读范围（2）巩固英语语法基础，掌握科技英语的语言特点（3）针对应用文体加强翻译、写作练习,62,
