In the passage the writer claims that the dinosaurs are endotherms by discussing the polar dinosaurs, the leg position of dinosaurs and the Haversian canals.However, the professor challenges all three reasons and thinks the conclusion is untenable.

First, the article states that the polar dinosaurs could not have survived if they were not endotherms,which is doubted by the lecturer.She argues that it is possible weather in the period those dinosaurs lived in the polar region is warmer than today so that dinosaurs could live even they are not endotherms.And when it became colder, these dinosaurs may have moved to some other places where are suitable to live.Also, the professor claims that dinosaurs may hibernated during the cold period.

Secondly, the writer views that the the leg position can be regarded as a reason why dinosaurs are endotherms,which,nevertheless, contradicts with the professor’s opinion.The professor disputes that the leg underneath the body is better for supporting more weight which is advantage for them.

Thirdly, the evident that many dinosaurs have Haversian canals are also casted doubt on in the lecture.In the lecture, professor points out that the growth rings which shows that dinosaurs grow slower or stop growing in the cold period and reflect a periodic pattern which is different from endotherms who are growing fast even under the cold weather.

Consequently,it is somewhat hasty in the article to draw a conclusion that dinosaurs are endotherms.

In the passage the writer claims that the dinosaurs are endotherms by discussing the polar dinosaurs, the leg position of dinosaurs and the Haversian canals.However, the professor challenges all three reasons and thinks the conclusion is untenable.


First, the article states that the polar dinosaurs could not have survived if they were not endotherms,which is doubted by the lecturer.She argues that it is possible weather in the period those dinosaurs lived in the polar region is warmer than today so that dinosaurs could live even they are not endotherms（注意时态）.And when it became colder, these dinosaurs may have moved to some other places where are suitable to live.Also, the professor claims that dinosaurs may hibernated during the cold period.


Secondly, the writer views that the the leg position can be regarded as a reason why dinosaurs are endotherms,which,nevertheless, contradicts with the professor’s opinion.The professor disputes that the leg underneath the body is better for supporting more weight which is advantage for them.（这里是你没有听清吗？还有一些细节词可以写）


Thirdly, the evident that many dinosaurs have Haversian canals are also casted doubt on in the lecture.In the lecture, professor points out that the growth rings which shows that dinosaurs grow slower or stop growing in the cold period and reflect a periodic pattern which is different from endotherms who are growing fast even under the cold weather.（注意时态的差别，恐龙是在过去。同时你看你套了太多的从句，that后面的部分其实少了个谓语。一个复合句用两个从句就够了，达到上限了，没必要从句套从句，不如分成几个句子写，换成动词的分词形式写，更能体现多样化）


Consequently,it is somewhat hasty in the article to draw a conclusion that dinosaurs are endotherms.
