听力填空

本听力材料来自于老托partb,partc,是公认实施有效的听写材料,对于上手托福时间不长的同学非常适合。我曾经一次短时间备考听力提高了7分也归功老托。希望大家和我一样一定要坚持下来噢。相信坚持学习的同学听力上都会有很大的飞跃!

Nopain, no gain.我们的安排是这样的,第一遍用听力软件精听材料(建议做单句听写,听写的时候不要偷看我给的挖空题),然后按照我给的挖空题填关键词,回复后即可看到听力原文和文章精解,我将把难点和易错点oneby one 分析给大家。

回复填空答案格式如下:1____2____3____...et.al.

Before I tell you about the interesting ______ related to Tyrannosaurus rex, I need to review something we studied last semester --- the difference between what are commonly called cold-blooded and warm-blooded animals. In warm-blooded animals, birds and mammals, for example, the body temperature normally stays within a ______ range, no matter what the outside temperature is. As a result, a warm-blooded animal is usually active in both cold and hot weather because its body temperature can adjust to the temperature of its environment.
On the other hand, cold-blooded animals, such as most reptiles, amphibians, and insects, are unable to create enough heat ______to raise their temperature above the temperature of the environment. So, for example, the temperature of a cold-blooded animal falls when the environment is cool.
I hope this _______ is clear. Now, moving on to Tyrannosaurus rex... you may know that dinosaurs, being reptiles, are generally believed to have been cold-blooded. Well, a recent research study found that the chemical composition of the bones of Tyrannosaurus rex was _____ with the bones of an animal that has a very narrow range of internal temperature, indicating that it was probably warm-blooded.

答案原文

As a result, a warm-blooded animal is usually active in both cold and hot weather because its body temperature can adjust to the temperature of its environment.
On the other hand, cold-blooded animals, such as most reptiles, amphibians, and insects, are unable to create enough heat internally to raise their temperature above the temperature of the environment. So, for example, the temperature of a cold-blooded animal falls when the environment is cool.
I hope this distinction is clear. Now, moving on to Tyrannosaurus rex... you may know that dinosaurs, being reptiles, are generally believed to have been cold-blooded. Well, a recent research study found that the chemical composition of the bones of Tyrannosaurus rex was consistent with the bones of an animal that has a very narrow range of internal temperature, indicating that it was probably warm-blooded.

精解译文


【听力精解】

今天容我吐个槽,怎么这个听力越来越邪乎了,这次干脆来了一个又长又难记的名字,说了一串也听不太懂,后来查了一下才知道,原来这个Tyrannosaurus rex 是专有名词雷克斯霸王龙(恐龙名称),于是大家就自己意会一下吧~

这次的听力仍旧跟上次的有些许关联,也提到了冷血动物和warm-blooded 动物(这是温血动物,这翻译怪怪的,关于生物的这部分我不是很懂,大家有学过这部分知识的可以向我提出补充一下)

于是干脆普及一下这系列的词汇

amphibians 两栖动物

reptiles 爬行动物

mammals 哺乳动物

chemical composition 化学合成

internal 和 external 是 内部的 和 外部的

【参考译文】

霸王龙有关的有趣的发现之前,我告诉你,我需要检讨的东西,我们研究的最后一个学期---之间的差异通常被称为冷血动物和温血动物。在温血动物,鸟类和哺乳动物,例如,人体温度通常保持在一个狭窄的范围内,不管外面的温度是什么。因此,温血动物在寒冷和炎热的天气通常是积极的,因为它可以调节体温其环境温度。
另一方面,大多数爬行动物,两栖动物和昆虫,如冷血动物是国内无法创造足够的热量,以提高他们的温度高于环境温度。因此,举例来说,一个冷血的动物当环境温度降到凉爽。
我希望这种区别是显而易见的。现在,移动到霸王龙...你可知道,恐龙,爬行动物,一般被认为已冷血。嗯,最近的一项研究发现,霸王龙骨骼的化学成分与动物的骨头,有一个内部的温度范围很窄一致,这表明它可能是温血动物。

祝大家每天进步一点点!
