Faith begins by believing in your heart that what is right has a chance. 信念始于内心对机缘深信不疑。 Faith is knowing in your heart that good can overcome evil, that the sun can shine in a rainstrom. 信念是心底深信善良能战胜邪恶，太阳会在暴风雨中升

Maria的嗓子有些像流行天后Mariah Carey，但是比后者要稍微男性一点点。她的声线非常好，性感但不做作，有力但不炫耀，明亮但不过分照人。她的低音很沉，很女人但是又很自立，高音千回百转，闻之泪下。这首单曲中，诱惑力，爱情，妖娆的盘绕让人无法拒绝。有穿透力的声

Alan Austen went up certain dark and creaky stairs and peered about for a long time on the dime landing before he found the name he wanted written obscurely on one of the doors. He pushed open this door and found himself in a tiny room, which contain

Thats what it wants to hear, because that sound is gonna mean thats where lunch is. A battle with Triceratops is more often than not a fight to the death. This herbivore has evolved into a tank. Now, as a Tyrannosaur specialist, I dont like to admit

Tyrannosaurus Rex was of ten thousand pound, self-propelled, antitank weapon. Now, sixty five million years later, cutting-edge imaging technology lets us look deep inside their bodies to reveal just how the worlds greatest carnivores really work. Di

The jaws of T-Rex are infamous and lethal, housing sixty teeth with some as long as 30 centimeters. Its skull is constructed of 64 bones designed to be light but strong. Its 16 times stronger than the jaws of an alligator. The front teeth are dagger-

Its unlike any other creature that has walked the planet. T-Rex is different. Something about Tyrannosaurs and Tyrannosaurus Rex itself is different than other predatory dinosaurs. But for such a celebrated killer able to take on the toughest creatur

Hearing, smell and sight are all well refined. We can look at the sense of vision and see the attributes of a predator. T-Rexs eyes are 40 centimetres apart providing exceptional binocular vision, the ability to perceive depth. An eye is essentially

Sauroposeidon towers over Deinonychus. In fact, its mammoth size is its primary defense. But this giant begins life very small. For Deinonychus, Sauroposeiden would be a great meal, at least the juveniles, because there wouldve been lots of them and

And Sauroposeidon like most plant eaters are smelly. Unlike a meat eater, they produce huge amounts of waste, feces that form a trail marking everywhere theyve been. For Deinonychus, that odor is a dead giveaway. And this carnivores eyes can clearly

They are actually increasing their chance of getting a meal. Its a strategy still used today. Working together, lions will take on prey as big as a four-ton elephant, and they only have teeth and claws. Deinonychus employs an array of weaponry more p

Deinonychus instinctively knows to go for this giants weak spot, its neck. Youve got the windpipe there. Youve got the jugular vein, which if opened up will mean that that Sauroposeidon is dead meat. But death does not come quickly or pleasantly. For

Picture a living plane, and that gives you a sense of what Quetzalcoatlus would look like in life. And this is an animal that probably accelerates over 2.5Gs just on takeoff. Just beyond our comprehension. A Quetzalcoatlus is 10 times the weight of t

Attacking another T-Rex may seem like suicide, but a creature with such a voracious appetite has to find food by any means. Cannibalism is the rule. Its not the exception. If youre a carnivore and theres meat there, you take advantage of it. In fact,

--The irony for many predators is they are very concerned about injuring themselves. Even the toughest most well-armed man-eaters regularly come face to face with prey that can kill them. Whether you had the jaws of a Tyrannosaurus Rex, or are armed

Nothing this large would achieve powered flight until the 20th century, 65 million years later. And Quetzalcoatlus still may hold the record for flight duration. Probably stay aloft for a week. Probably it could have gone for 25, 26,000 miles in a si

I think that a big pterosaur on the ground wouldve been spooky because they would be moving around on all fours. Theyd probably have those sort of quick, precise movements like birds, but theyd be huge. Quetzalcoatlus lives by its own rules. Most mea

Other carnivores are even more dependent on cognitive thought. For protection, Deinonychus relies primarily on its brain. --The brain structure of Deinonychus and its role are just really quite remarkable. Relatively speaking, Deinonychus has one of

Mighty carnivores ruled a dangerous world in the Cretaceous Period. But being a super predator like Tyrannosaurus Rex is not easy. Just surviving to adulthood is a major feat, one that takes a decade or more of killing and eating some of the meanest
