一、题目

俗话说“题好一半文”，一个好题目，等于是一篇好作文的开端，题目要新颖，与众不同才能引人注目!

二、开头、结尾

文章的开头是龙头，结尾则是凤尾。开头多种多样，一旦想出好开头，笔头的文思就会源源流出。常见开头有以下几种：1、开门见山。2、提问引人关注。3、概括揭示。4、描写环境。5、倒叙，制造悬念。这样，才会制造一个好开头，才是一篇好文章的开端。

“编筐编篓，全在收口”。文章中的结尾也是其文章精华之处，有的结尾发人深思，有的结尾自然收笔，有的结尾刁钻古怪，耐人回味，还有的结尾，要挑选一种比较与文章相配的结尾来写，收笔也美观大方。

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 从南德国的一块美妙地被保存的化石在星期四出版的研究中提出关于羽毛怎么从恐龙演变了到鸟，二个古生物学家的问题争论。

The 150百万年老化石是少年食肉恐龙大约科学家命名Juravenator的2 1/2英尺长，为找到的朱拉山。

在“失去的世界期间，开头场面It将看起来类似在生活中恐吓海滩的一个女孩的走路快的掠食性动物”，第二部侏罗纪公园**。

The化石的相当好被保存的骨头结构在恐龙家谱明显地投入它在用羽毛装饰的家族之中。 由于所有它的近亲用羽毛装饰，古生物学家会盼望Juravenator仿效别人。

But皮肤一个小补丁在生物的尾巴的不显示羽毛的迹象。 并且皮肤也没有是特点用羽毛装饰的恐龙的滤泡，说Luis Chiappe，恐龙学院的主任洛杉矶县自然历史博物馆的。 慕尼黑大学的他和厄休拉B Gohlich在学报自然的星期四的问题描述化石。

"它有典型的鳞状dinosaurian皮肤， “Chiappe说。

The古生物学家相信Juravenator的最接近的已知的亲戚也许是从中国， Sinosauropterix的充分地用羽毛装饰的恐龙。

There是Juravenator的裸体的一定数量的可能解说。 羽毛在带领Juravenator在升起在祖先以后两个它和它的用羽毛装饰的亲戚的演变线可能丢失了。 或者羽毛在恐龙可能不止一次演变了，突然发生在姐妹种类在不同的时间和地点。 也是可能的Juravenator这块特殊化石，看来少年，只有生长了羽毛作为成人或丢失了它的一部分的羽毛的年。

那里But是另一种可能性，说标记Norell，古生物学的馆长在自然历史美国博物馆的： 是完全可能的Juravenator有羽毛，但是他们没有僵化。

"羽毛是真正地保存的困难的事， “Norell说。

To支持他的假说他指出最旧的已知的鸟，始祖鸟，缺乏的几块化石用羽毛装饰。

新的标本是否提出关于羽毛�0�3 �0�9和鸟�0�3 �0�9怎样的有趣的问题因而演变了，多数专家不看它，因为挑战对广泛被接受的观点现代鸟下降恐龙

父母对我的爱

Love for my parents

有句古训：“百善孝为先”。这句是时常挂在人们嘴边的话，却蕴含着人世间最伟大的爱。

There is old saying:" filial piety" This is often people hanging out at the mouth, it contains the greatest love of all

小时候，躺在妈妈的怀里，吸着甘甜的乳汁，咿呀学语。这是我们童年最美好的回忆。再大些，学习成了我们主要的任务,在艰辛的学习过程中，父母是我们停泊船只的岸边。伴随我们踏出一步步成长的脚印。

When I was young, lie in the arms of mother, sipping sweet milk, babbling This is our most wonderful childhood memories More, learning has become our main task, the hardships of the learning process, the parents of our ship shore As we step out to grow step by step

有一次，我在过马路时看到过这样一幕感人的故事：有一只猫，偷了主人家的一条鱼，主人发现了，拿着棒子去追猫，把猫的一条腿都快要打断了，可猫仍不松口。最后这只猫终于摆脱了主人的追打，来到了一边草地，停了下来。把鱼放到一只小猫面前，小猫贪婪地吃着，而那只猫妈妈只是用舌头慈爱地舔着小猫的头。那条几乎是用生命换来的鱼，它却始终没有吃一口，看到这，我都感动的快要流泪了。这就是爱，一个母亲对自己孩子的爱。

Once, I was crossing the road when seen such a moving story: a cat, stealing the master's a fish, the master found out, carrying stick to chase the cat, the cat 's leg was interrupted, but the cat is still not let go Finally, the cat came out of the owner's chase, came to the side of the grass, stopped Put the fish in a kitten in front, the cat ate greedily, but the cat mother tongue lovingly lick kitten's head The almost 's life in exchange for the fish, it is not always eat, see this, I was moved to tears This is love, a mother love to their children

在人世间谁何尝不知：“羊羔有跪乳之恩，乌鸦有反哺之意。而作为子女，一句“谢谢”，

In this world who do know:" lamb with filial piety, crow are feeding As a child, saying " thank you",

怎能挽回父母对我没的爱呢？父母虽然没有受过良好的教育，带他们有人世间最伟大的爱。生活压弯了他们的身躯，带光阴流过，却在他们铺满皱纹的脸上写下了岁月的痕迹。

How to save the parents of my love Although they have received a good education, they have the greatest love of all Life with their bodies, with time through, but in their covered with wrinkles on the face and wrote the traces of time

九年的时光在我生命的白纸上画下了一条长长的轨迹，九年的时光如流水般轻易地偷走了您最宝贵的岁月。我已不再是一个咿呀学语的孩子了，我懂得了父母的用心良苦。岁月缓缓的推动历史的车轮，我懂了。什么是“大爱无疆”。

In nine years time in my life and white painted on a long track, nine years such as water easily stole your most valuable time I am no longer a child learn language, I understand that parents have cudgeled one's brains The years slowly push the wheel of history, I understand What is love""

父母的爱比山高，比海深，更比日月长。我愿以一颗满怀感的心祈祷上苍，愿我的父母平安幸福。

Parental love is higher than the mountains, deeper than the sea, more than the sun and the moon long I would like a full of feeling heart to pray to God, let my parents happy
