  如何在充满专业词汇的文章中顶住压力进行阅读?针对这个问题,下面新航道重庆学校托福教研组Cara老师给大家分析下。

  由于托福的文章话题性较强,所以阅读过程当中会呈现以下的情况。文章当中有相当比例的单词是同学们不熟悉的,多数时候它们往往跟一些专业话题相关。接下来我们以TPO48的文章“determining dinosaur diet”来给大家进行分析,我们如何在这些单词当中找到关键,并且积累托福生物话题必备的词汇与背景知识。

  Problems:

  在下面的两个段落当中:高亮的单词为学生们经常出错或者直接不认识的词汇,这部分词汇在考场上会给大家,尤其是不熟悉考试模式的同学带来巨大的压力。

  In the stomach contents of specimens of Coelophysis (a small, long-necked dinosaur) are bones from juvenile animals of the same species. At one time, these were thought to represent embryonic animals, suggesting that this small dinosaur gave birth to live young rather than laying eggs. Further research indicated that the small dinosaurs were too large and too well developed to be prehatchling young. In addition, the juveniles inside the body cavity were of different sizes. All the evidence points to the conclusion that these are the remains of prey items and that, as an adult, Coelophysis was at least in part a cannibal.

  Fossilized stomach contents are not restricted to carnivorous dinosaurs. In a few rare cases, most of them “mummies” (unusually well preserved specimens), fossilized plant remains have been found inside the body cavity of hadrosaurs. Some paleontologists have argued that these represent stream accumulations rather than final meals. The best known of these cases is the second Edmontosaurus mummy collected by the Sternbergs. In the chest cavity of this specimen, which is housed in the Senckenberg Museum in Germany, are the fossil remains of conifer needles, twigs, seeds, and fruits. Similar finds in Corythosaurus specimens from Alberta, Canada, have also been reported, indicating that at least two kinds of Late Cretaceous hadrosaurs fed on the sorts of tress that are common in today's boreal woodlands.

  Solutions:

  但是实际情况是怎么样的呢,首先,刚刚我们高亮的单词,其实一大半都不需要我们掌握中文含义,它们甚至不会影响我们解题和了解段落重点。那么这些单词我们可以给他们一个统一的名字“非考点词”或者“低频话题词”。那这些“非考点词”有什么标志吗?仔细观察我们就会发现,它们多数都是以大写的形式出现:比如Edmontosaurus, Senckenberg……, 或者这些单词后面往往会有括号进行解释说明:比如coelophysis (a small, long-necked dinosaur),那我们就只需要知道coelophysis是a kind of dinosaur那就足够了。所以大写的信息往往我们都可以一定程度上忽略。

  其次,大家会发现还有一部分单词剩下来了,那这部分单词其实就是“考点词”当中跟学科相联系的,在学科当中常见的词汇。它们需要同学背诵记忆下来,但是由于多数同学在考托福之前都没有专门积累过一些生物学的词汇,所以会觉得比较难。那这样一些生物学当中常考的话题词汇其实咱们只需要在接触此类话题的初期,进行专门的积累,那么这类话题的困难性将大大降低。
