（单词翻译）

 The jaws1 of T-Rex are infamous2 and lethal3, housing sixty teeth with some as long as 30 centimeters. Its skull4 is constructed of 64 bones designed to be light but strong. It’s 16 times stronger than the jaws of an alligator5. The front teeth are dagger-shaped, with serrated edges designed to tear flesh. The larger side teeth are rounded, perfect for crunching6 bone. Solidly anchored into muscle, they could withstand pressure from any direction. 

 
We have a pretty good idea of how it killed its prey7. It seems to have just walked right up to them, taken a bite, and whatever happens happens. 
 
Unlike many dinosaurs8, they wouldn’t just take the flesh of the carcass. They basically eat most of the carcass.
 
T-Rex’s huge legs and pelvis make up half its total body weight. Its tail weighs almost a ton. This is because it has to balance out nearly half a ton of head and jaws. Their head is two thirds muscle, which power jaws capable of enough force to bite through a steel oil drum. 
 
All that muscle delivers a bite strong enough to defeat the toughest prey of the Cretaceous. 
 
T-Rex’s teeth are among the bluntest teeth, bluntest, least sharp of the whole family of Tyrannosaurs. Those teeth are designed to crush, to penetrate9 thick layers of armor, and muscle, in a crushing, massive hemorrhaging blow. 
 
The muscles in T-Rex’s neck are nearly as powerful as the muscles of its legs. At half a meter thick, they’re strong enough to lift a hippo or bring down the most well-armed, best-defended herbivore nature has ever produced, Triceratops. 
 
The best way to attack Triceratops is with a long-barreled, 75 millimeter antitank gun.
