　　A beautifully preserved fossil from southern Germany raises questions about how feathers evolved from dinosaurs to birds, two paleontologists argue in a study published Thursday.

　　The 150 million-year-old fossil is a juvenile carnivorous dinosaur about 2 1/2 feet long that scientists named Juravenator, for the Jura mountains where it was found.

　　It would have looked similar in life to the fleet-footed predators that menaced a young girl on the beach during the opening scene of "The Lost World," the second Jurassic Park movie.

　　The fossil’s exceptionally well-preserved bone structure clearly puts it among feathered kin on the dinosaur family tree. Because all of its close relatives are feathered, paleontologists would expect Juravenator to follow suit.

　　But a small patch of skin on the creature’s tail shows no sign of feathers. And the skin also doesn’t have the follicles that are typical of feathered dinosaurs, said Luis Chiappe, director of the Dinosaur Institute at the Natural History Museum of Los Angeles County. He and Ursula B. Gohlich of the University of Munich describe the fossil in Thursday’s issue of the journal Nature.

　　"It has a typical scaly dinosaurian skin," Chiappe said.

　　The paleontologists believe Juravenator’s closest known relative may have been a fully feathered dinosaur from China, Sinosauropterix.

　　There are a number of possible explanations for Juravenator’s nakedness. Feathers could have been lost on the evolutionary line leading to Juravenator after arising in an ancestor to both it and its feathered relatives. Or feathers could have evolved more than once in dinosaurs, cropping up in sister species at different times and places. It is also possible that this particular fossil of Juravenator, which appears to be a juvenile, only grew feathers as an adult or lost its feathers for part of the year.

　　But there is another possibility as well, said Mark Norell, curator of paleontology at the American Museum of Natural History: It is entirely possible that Juravenator did have feathers, but they simply failed to fossilize.

　　"Feathers are really just difficult things to preserve," Norell said.

　　To support his hypothesis he pointed out that several fossils of the oldest known bird, archaeopteryx, lack feathers.

　　Whether or not the new specimen raises interesting questions about how feathers — and thus birds — evolved, most experts do not see it as a challenge to the widely accepted view that modern birds are descended from dinosaurs.

　　考研相關英語作文：老師改變了男孩的人生

　　Steve, a twelve-year-old boy with alcoholic parents, was about to be lost forever, by the U.S. education system. Remarkably, he could read, yet, in spite of his reading skills, Steve was failing. He had been failing since first grade, as he was passed on from grade to grade. Steve was a big boy, looking more like a teenager than a twelve year old, yet, Steve went unnoticed... until Miss White.

　　Miss White was a smiling, young, beautiful redhead, and Steve was in love! For the first time in his young life, he couldn’t take his eyes off his teacher; yet, still he failed. He never did his homework, and he was always in trouble with Miss White. His heart would break under her sharp words, and when he was punished for failing to turn in his homework, he felt just miserable! Still, he did not study.

　　In the middle of the first semester of school, the entire seventh grade was tested for basic skills. Steve hurried through his tests, and continued to dream of other things, as the day wore on. His heart was not in school, but in the woods, where he often escaped alone, trying to shut out the sights, sounds and smells of his alcoholic home. No one checked on him to see if he was safe. No one knew he was gone, because no one was sober enough to care. Oddly, Steve never missed a day of school.

　　One day, Miss White’s impatient voice broke into his daydreams.

　　“Steve!!” Startled, he turned to look at her.

　　“Pay attention!”

　　Steve locked his gaze on Miss White with adolescent adoration, as she began to go over the test results for the seventh grade.

　　“You all did pretty well,” she told the class, “except for one boy, and it breaks my heart to tell you this, but...” She hesitated, pinning Steve to his seat with a sharp stare, her eyes searching his face.

　　“...The smartest boy in the seventh grade is failing my class!”

　　She just stared at Steve, as the class spun around for a good look. Steve dropped his eyes and carefully examined his fingertips.

　　After that, it was war!! Steve still wouldn’t do his homework. Even as the punishments became more severe, he remained stubborn.

　　“Just try it! ONE WEEK!” He was unmoved.

　　“You’re smart enough! You’ll see a change!” Nothing fazed him.

　　“Give yourself a chance! Don’t give up on your life!” Nothing.

　　“Steve! Please! I care about you!”

　　Wow! Suddenly, Steve got it!! Someone cared about him? Someone, totally unattainable and perfect, CARED ABOUT HIM??!!

　　Steve went home from school, thoughtful, that afternoon. Walking into the house, he took one look around. Both parents were passed out, in various stages of undress, and the stench was overpowering! He, quickly, gathered up his camping gear, a jar of peanut butter, a loaf of bread, a bottle of water, and this time...his schoolbooks. Grim faced and determined, he headed for the woods.

　　考研相關英語作文：On Keeping a Diary in English

　　Keeping a diary in English is one of the effective ways to improve our English writing ability. Compared with other forms of writing, it is shorter and takes less time. It can help us to cultivate the habit of thinking in English. If we persist in his practice, gradually we’ll learn how to express ourselves in English.

　　In keeping a diary in English, we inevitably run up against a lot of difficulties. In the first place, it often happens that we have trouble finding appropriate words and phrases to give expression to our mind. Secondly, there are many idiomatic ways of saying things in Chinese. And it is extremely hard for us to put them into English properly. Certainly, there are some other roadblocks we may come across in our keeping a diary in English.

　　As far as I’m concerned, my suggestion is that we should always have a note book and a Chinese-English dictionary within easy reach. Whenever something beats us, we can first put it down in our notebook and then consult our dictionary. We can also turn to our English teacher for help, if necessary. In short, it is of great use to keep a diary in English for the development of our writing skills.
