在阅读文章中，作者声称大型翼龙无法进行动力飞行。但是，演讲者由于以下三

In reading the article, the author can not claim that large pterosaurs powered flight. However, the speaker for the following three reasons contradict this view. <br><br>First, read the material pointed out that the ancient reptiles such as pterosaurs may be cold-blooded and can not generate enough energy to fly. But the speaker countered that the pterosaur has a dense, hairlike covering, which is typical of warm-blooded animals, their metabolism can provide the energy needed to power flight. <br><br>Second, the authors note that pterosaurs too heavy to stay at any time. But the lecturer recommended pterosaur bones are hollow, rather than solid. Thus, despite the large pterosaur body, but the weight of pterosaurs could very light, enough to keep them in their flight by flapping its wings. <br><br>Finally, the authors point out the lack of a sufficiently large pterosaur hind legs and powerful muscles, could not run fast or jump high, unable to fly into the air. Instead of reading the article, speakers stressed the hind legs of the birds using only different pterosaurs to use four limbs to push it off the ground.

In contrast to reading the article, the speaker emphasized that, unlike birds that use only the hind limbs, pterosaurs use four limbs to push them off the ground.

In the reading, the author claims that large pterosaurs cannot fly with power. However, the speaker contradicts this view for three reasons.<br>First, the reading points out that ancient reptiles like pterosaurs may be cold-blooded and unable to generate enough energy to fly.

But the instructor suggested that the pterosaur's bones were hollow, not solid. So, despite their size, pterosaurs may be light enough to keep them in the air by flapping their wings.<br>At last, the author points out that pterosaur's hind legs are lack of large and powerful muscles, so it can't run fast or jump high enough to fly in the air. Instead of reading the article, the speaker stressed that unlike birds that use only hind legs, pterosaurs use four limbs to push them off the ground.<br>
