摘要
英国科学家克里斯汀·马格斯40年前在珊瑚藻床上发现一种粉红条纹小海藻,如今研究人员终于采集到足够样本进行DNA检测,证实这是一个全新物种。
A British scientist has confirmed that a tiny pink-striped seaweed she first discovered 40 years ago on a maerl bed is an entirely new species, after researchers finally gathered enough material for DNA testing.
长难句拆解
And 40 years ago, while studying one such bed for her PhD, Prof Christine Maggs found a fragment of pink-striped seaweed living on maerl she had never seen before.40年前,克里斯汀·马格斯教授在为博士学位研究一处这样的珊瑚藻床时,发现了一小片生长在珊瑚藻上、她从未见过的粉红条纹海藻碎片。
主干:While A, Prof Maggs found B.
先抓住主干——'Maggs教授发现了一小块海藻',其余部分只是在交代发现的时间背景,以及描述这海藻长什么样、长在哪里。
- 省略主语和be动词的时间状语从句:完整形式应为'while she was studying...'。当while从句的主语和主句主语相同(都是Maggs教授)时,英语习惯省去主语和be动词,只保留doing形式,使句子更紧凑。
- 现在分词作后置修饰语:'living on maerl'紧跟在'seaweed'后面,是对海藻状态的补充说明,相当于一个简化的定语从句'which was living on maerl',不需要引导词。
- 省略关系代词的定语从句:这里省略了that/which,完整应为'[that] she had never seen before'。因为关系代词在从句中作宾语(seen的宾语),可以省略。这个从句语义上修饰的是前面整个'一小块海藻',而不是紧邻的'maerl'。
- 过去完成时表示'发现之前从未有过'的状态:'had never seen'用过去完成时,表示在'found'(过去发生的发现动作)之前的一段时间里,她从未见过这种海藻,强调这是她生平第一次见到。
Prof Maggs bought a wine fridge in anticipation, the perfect dark, cool environment to store it while tests were carried out to prove it was, indeed, a new species.马格斯教授提前买了一台红酒冰柜——这是存放样本的理想阴凉环境——用于在检测期间保存样本,以证实它确实是一个新物种。
主干:A bought B in anticipation, C, to store it while D were carried out to prove it was a new species.
句子主干只是'A买了B',后面一大串都是在解释这个红酒柜的用途和购买动机,不是并列的新主句。
- 同位语说明红酒柜的用途:逗号后的名词短语是对前面'a wine fridge'的补充说明(同位语),直接说明这个红酒柜就是理想的黑暗阴凉存储环境,而不是另起一句。
- in anticipation 表示'提前/预先':'in anticipation'意思是'提前预料到会有需要,先做准备',暗示玛格斯教授还没等结果出来就已经在为储存样本做准备,反映她对这次发现的期待。
- 被动语态 tests were carried out:用被动语态是因为句子关注的是'检测这件事本身',而不是谁去做检测;执行检测的人在句中没有被提及,也不重要。
- 两层嵌套的目的不定式:句中有两层'为了做什么'的目的关系:买这个环境是'为了存放样本(to store it)',而存放期间做检测又是'为了证明它是新物种(to prove...)'。理解这两层目的的先后关系是读懂全句的关键。
- while 表示两件事同时发生:'while'在这里表示'在……期间/与此同时',说明样本被存放的这段时间,正好也是检测在进行的时间,两个动作是同步的。
- 插入语 indeed 强调确认:'indeed'被逗号夹在中间插入句子,起强调作用,意思接近'果然、确实',暗示这正是玛格斯教授多年来一直期盼确认的结果。
He said it could also add to interest in protecting maerl beds, which were "already of the greatest importance to all of the other plants, animals and microbes in the ecological community that they support".他表示,这也可能进一步激发人们保护珊瑚藻床的兴趣,因为这些藻床“对其所支撑的生态群落中的其他所有植物、动物和微生物而言,本就至关重要”。
主干:He said A could add to interest in protecting B, which were already of the greatest importance to C.
先抓主干:他说这个发现能提升保护maerl海床的兴趣;再看修饰海床的从句:海床本身早就对它所支撑的整个生态群落至关重要。
- 省略的that引导宾语从句:said后面省略了连接词that,真正的宾语从句是it could also add to interest in protecting maerl beds,即谢耐德教授转述的内容,而不是两个独立的句子。
- could表示委婉的推测可能性:这里的could不是单纯的过去时,而是表示对未来的委婉推测:这项发现有可能会增加人们保护maerl海床的兴趣,语气比will更谨慎。
- 非限制性定语从句which修饰maerl beds:逗号加which引导的非限制性定语从句,只是对maerl beds做补充说明,去掉它主句意思依然完整。
- be of + 抽象名词 表示性质程度:be动词+of+抽象名词短语相当于be+形容词,were of the greatest importance即were extremely important(极其重要),这是较正式的书面表达。
- 嵌套从句中they指代对象:that they support修饰前面的the ecological community,they指代更前面的maerl beds,整体意思是maerl海床所支撑的这个生态群落,而不是群落里的动植物自己支撑自己。
