托福TPO4综合写作阅读+听力原文+满分范文

2018-12-16 18:50:49 发布 来源:雷哥托福 阅读量:2680

在备考托福写作的过程中,总是将托福的独立作文放在了第一位,但是实际上,综合作文也是占到了作文总分30分里面的50%的分值,不要等到分数出来了,才发现其实是综合作文的limited或者fair极大的影响了自己的分数。

考过的同学会发现托福综合作文分数不高,很大程度上是受我们听力实力的影响,我们很多托福考生的听力分数只有16分上下的时候,对于托福综合作文的听力妥妥的是束手无策,而且很多托福考生还感觉自己都听懂了,那也只能说明你听懂了大意,但是听力里面要的是每一个细节!请注意,是每一个细节!

雷哥托福小托君给大家分享TPO1-33综合作文部分的阅读和听力文本全集与综合作文的满分作文,以及满分作文的解析。如果自己的托福综合作文分数如果可以很给力的话,就已经搞定了15分的分数,可以极大地缓解托福独立作文的压力。如何使用这个文件呢?

Reading

Endotherms are animals such as modern birds and mammals that keep their body temperatures constant. For instance, humans are endotherms and maintain an internal temperature of 37°C, no matter whether the environment is warm or cold. Because dinosaurs were reptiles, and modern reptiles are not endotherms, it was long assumed that dinosaurs were not endotherms. However, dinosaurs differ in many ways from modem reptiles, and there is now considerable evidence that dinosaurs were, in fact, endotherms.

Polar dinosaurs

One reason for believing that dinosaurs were endotherms is that dinosaur fossils have been discovered in Polar Regions. Only animals that can maintain a temperature well above that of the surrounding environment could be active in such cold climates.

Leg position and movement

There is a connection between endothermy and the position and movement of the legs. The physiology of endothermy allows sustained physical activity, such as running. But running is efficient only if an animal's legs are positioned underneath its body, not at the body's side, as they are for crocodiles and many lizards. The legs of all modern endotherms are underneath the body, and so were the legs of dinosaurs. This strongly suggests that dinosaurs were endotherms.

Haversian canals

There is also a connection between endothermy and bone structure. The bones of endotherms usually include structures called Haversian canals. These canals house nerves and blood vessels that allow the living animal to grow quickly, and rapid body growth is in fact a characteristic of endothermy. The presence of Haversian canals in bone is a strong indicator that the animal is an endotherm, and fossilized bones of dinosaurs are usually dense with Haversian canals.


Listening

Professor: 

Many scientists have problems with the arguments you read in the passage. They don't think those arguments prove that dinosaurs were endotherms.

Take the polar dinosaur argument. When dinosaurs lived, even the polar regions, where dinosaur fossils have been found, were much warmer than today, warm enough during part of the year for animals that were not endotherms to live. And during the months when the polar regions were cold, the so-called polar dinosaurs could have migrated to warmer areas or hibernated like many modern reptiles do. So the presence of dinosaur fossils in polar regions doesn't prove the dinosaurs were endotherms.

Well, what about the fact that dinosaurs have their legs placed under their bodies, not out to the side like crocodiles. That doesn't necessarily mean dinosaurs were high-energy endotherms built for running. There is another explanation for having legs under the body. This body structure supports more weight, so with the legs under their bodies, dinosaurs can grow to a very large size. Being large had advantages for dinosaurs, so we don't need the idea of endothermy and running to explain why dinosaurs evolved to have their legs under their bodies.

Ok, so how about bone structure? Many dinosaur bones do have Haversian canals, that's true. The dinosaur bones also have growth rings. Growth rings are thickening of the bone that indicates periods of time when the dinosaurs weren't rapidly growing. These growth rings are evidence that dinosaurs stopped growing or grew more slowly during cooler periods. This pattern of periodic growth, you know, rapid growth followed by no growth or slow growth, and then rapid growth again, is characteristic of animals that are not endotherms. Animals that maintain a constant body temperature year-round as true endotherms do grow rapidly even when the environment becomes cool.


TPO4综合写作范文推荐Sample Response

The professor actually contradicts the statements made in the passage. She is of the view that dinosaurs are not endotherms i.e. they were not able to keep their body temperature at a constant rate.

The professor contradicts the issue of dinosaurs being endothers based on the availability of fossils being available in the polar regions, she say that the polar regions in those days were not as cold as they are today i.e. at least warm enough for dinosaurs to live. During harsh winters she says that there is a possibility of the dinosaurs actually migrating to warmer regions.

The issue of leg position and movement being used as a reason to classify the dinosaurs as endotherms does not please the professor either. She says that dinosaurs had legs under their bodies to support their huge bodies i.e. the legs under the body of the dinosaur were actually to support the huge weight of the dinosaur and not to provide it with a body structure like endotherms (which is actually suited for running).

The professor acknowledges the presence of haversian canals but also points out that that the fossils show the presence of growth rings. These rings occur due to the thickening of the bone.

The thickening indicates that the dinosaurs weren’t actually growing continuously but were experiencing periods of rapid growth and periods of no growth in succession. This pattern, she says is characteristic of non endothermic animals. Thus it can be inferred that the professor challenges the passage by giving reasons as to why she thinks that the dinosaur is not an endotherm.


首先,就是在自己做托福TPO模考之后,可以根据这里面的听力的文本,来检验自己的听力内容是否抓的足够好,尤其是要看写的够不够全!很多时候,我们的综合作文之所以分低,就是因为听力写的不全!

第二点,也可以用于在托福考试前来做跟读,有不少托福考生跟小托君说,自己的口语实力不够,那么做跟读,仔细地来模仿ETS官方素材,是一个很好的提高自己口语的方式。毕竟托福口语最终考的,是口语本身说的是否足够流畅,要想在考试的时候说的很流畅,就是要在平时张口多说,只有多说,我们才能够做到足够的流利。

第三点,熟悉托福考试的专业词汇。不少托福考生之所以在听力考试里面不够给力,是因为对于里面的专业词汇不够熟悉。毕竟在托福考试过程中,如果核心词汇都不懂的话,那么在听力部分只能是束手就擒了。因此,各位托福考生可以通过这份综合写作的听力和阅读材料,来熟悉托福作文之中的专业词汇。
