“海龟”变“海带”-2019年精选文档

海龟化石的形成过程作文英文回答：Formation Process of Turtle Fossils.Turtle fossils are formed through a fascinating process that involves several steps. It all begins when a turtle dies and its body sinks to the bottom of a body of water, such as a lake or an ocean. Over time, sediment, such as sand, mud, or silt, starts to accumulate on top of the turtle's remains.As more sediment accumulates, the weight and pressure increase, causing the bottom layers to compress. This compression helps to preserve the turtle's body by preventing it from decomposing too quickly. The sediment also acts as a protective layer, shielding the turtle's remains from scavengers and other external factors.Over thousands or even millions of years, the sedimentcontinues to accumulate, eventually burying the turtle's body completely. The weight of the sediment compacts the lower layers, turning them into sedimentary rock. This process, known as lithification, helps to preserve the turtle's remains by turning them into fossils.During lithification, minerals from the surrounding sediment seep into the turtle's bones, replacing the organic material with rock-like minerals. This process is called mineralization and is essential for the preservation of the fossil. The minerals help to harden the bones, making them more resistant to decay and providing a solid structure for the fossil.As time goes on, geological processes, such as erosion or tectonic activity, can expose the fossilized turtle remains. These fossils can be found in various locations around the world, from ancient seabeds to desert regions. Paleontologists study these fossils to learn more about the evolution and history of turtles.中文回答：海龟化石的形成过程。

什么原因让“海归”变成“海待”
“海龟”、“海带”本属海洋生物，但它们的谐音“海归”、“海待”由于比较形象地描述了中国海外留学归国人员的现状而成为新的中文名词。

一度倍受用人单位欢迎的“海归”为什么蜕变成被市场冷落的“海待”？人们自然能分析出诸多原因，像“海归”自我定位过高啦、有学历缺能力啦、观念不适应中国国情啦……一句话，“海归”成“海待”，主要责任在“海归”。

毫无疑问，“海归”变“海待”与“海归”自身的种种不足大有关系。

“海归”们确实应该如专家建议，按照中国市场的需求调整自己的心态和期望值。

但对整个中国经济、文化甚至政治而言，“海待”数量剧增绝对不是一个好现象。

尽管“海待”们有很多地方需要学习和改进，但他们在发达国家和地区接受过高等教育却是不争的事实(极少数“野鸡大学”混文凭的除外)。

在中国，他们的专长应该也完全可能得到发挥，否则，就算不说“报国无门”之类的大话，单是他们在海外求学时付出的高额投入也无以回收。

事实上，除了“海归”自身的原因外，中国社会也没有为容纳“海归”提供完全平等的条件。

例如，“海归”们只能在企业、学校和科研机构寻找就业机会，而党政机关和权力部门的大门仍没有向“海归”们开放。

甚至，社会舆论对“海归”变“海待”有时还流露出某种幸灾乐祸的心理。

认为“海归”是“假洋鬼子”的想法仍有市场，“海待”在求职中无论要求高薪还是低薪也可能成为媒体揶揄的话题。

中国的人才还远谈不上过剩，无论是什么原因让“海归”变成“海待”，都不仅是“海待”和他们家人的损失，也是整个国家的损失。

海归变“海带”，都在等什么

教育部数据显示，2015年度我国出国留学人员总数为52.37万人，回国40.91万人，较2014年增长了12.1%。

但海归们学成回国后，却遇上了就业难题。

这既有经济下行、就业岗位减少等外部因素，也有“个人期望值过高”、“眼高手低”和“不了解国内就业市场需求”等内在原因。

有的家长“砸锅卖铁”甚至举债，把孩子送出国门留学，为的是让孩子“开阔眼界长见识”，“能在求职时简历上增加亮点而胜出”……找工作时却遇到了“不如意”、“工作不理想”，甚至找不到“合适的工作”，让我们听听海归们的心声。

找工作成了全家的“一号任务”
24岁的留英硕士张佳玲回国几个月，投了几十份简历，却石沉大海。

她掰着手指数了
数，苦笑道：“我参加了4次面试和2次笔试，然后，就没有然后了。

”
更多的时间是在等待中度过的。

在不断刷新邮箱和生怕错过每一个陌生来电的期待中，张佳玲感到，花了1年多时间，搭进几十万元，好不容易给自己的学历镶上的金边，正在一天天被现实剥去光环。

给张佳玲找工作，成了全家的“一号任务”。

父母和亲戚启动了庞大的私人关系网络，这显然比大海捞针般广撒简历要高效得多。

好几个直接送上门的机会，都被张佳玲拒绝了。

先是父母托人帮她安排了一个在银行的工作，推销信贷产品，这让她觉得“干的和自己所学的专业差了十万八千里，实在不喜欢”。

亲戚先后给她介绍了好几份实习，可有的“工资低”，有的“不能。

海龟变成化石想象作文英文回答:As a turtle, I have lived a long and fulfilling life in the ocean. I have swum through the vast waters, encountered various marine creatures, and witnessed the beauty of coral reefs. However, one day, fate took an unexpected turn, and I found myself trapped in a layer of sediment. Slowly, over thousands of years, I transformed into a fossil.Being a fossil is a unique experience. I am now frozen in time, preserving the details of my existence for future generations to discover. Scientists can study my fossilized remains to learn about the ancient world and the creatures that inhabited it. They can analyze my shell to determine my age, diet, and even the environmental conditions during my lifetime.In addition to scientific value, my fossil also holds cultural significance. People can marvel at the intricatepatterns on my shell and imagine the vibrant colors that once adorned my body. My fossil can serve as a reminder of the rich biodiversity that once thrived in the oceans and the importance of preserving our natural world.中文回答：作为一只海龟，我在海洋中度过了漫长而充实的一生。

海龟化石的形成故事三百字作文英文回答：The formation of turtle fossils is an intriguing story that spans millions of years. It all begins with the life of a turtle, living in a lush and vibrant environment. As the turtle goes about its daily activities, such as swimming, eating, and basking in the sun, it leaves behind traces of its existence. These traces can include bones, shells, and even footprints.Over time, the turtle's remains become buried under layers of sediment. This can happen due to natural processes like erosion or deposition of sediments by water or wind. As more and more sediment accumulates, theturtle's remains are gradually compressed and hardened. This process, known as diagenesis, transforms the soft tissues and bones into rock-like structures.As the turtle's remains undergo diagenesis, they canalso undergo mineralization. This occurs when minerals from the surrounding sediment seep into the pores and spaces within the remains, replacing the original organic material. The most common minerals involved in this process aresilica, calcite, and pyrite. The minerals not only preserve the structure of the turtle's remains but also give them their characteristic fossilized appearance.After millions of years, geological forces such as tectonic activity or erosion bring the fossilized turtle remains back to the surface. Paleontologists and fossil hunters then discover these fossils, providing valuable insights into the ancient world and the evolution ofturtles.中文回答：海龟化石的形成是一个跨越数百万年的引人入胜的故事。

龟类化石形成的过程作文400字英文回答：Fossil Formation of Turtles.The fossilization process of turtles is a complex and fascinating one that involves a series of intricate steps. These steps include:Death and Burial: The process begins when a turtledies and is subsequently buried by sediment. The sediment acts as a protective layer, preventing the turtle's body from being scavenged or decomposed by microorganisms.Decay and Soft Tissue Removal: Over time, the turtle's body begins to decay, and its soft tissues, such as muscles, organs, and skin, are gradually broken down and removed by microorganisms and other natural processes.Mineralization: As the soft tissues are removed,minerals from the surrounding environment begin to seepinto the turtle's remains. These minerals, which are often composed of calcium carbonate or silica, gradually replace the organic matter, creating a mineral replica of theturtle's original skeleton.Hardening and Preservation: The mineralization process gradually hardens the turtle's remains, turning them into a solid fossil. The fossil is now resistant to further decay and can be preserved for millions of years.中文回答：乌龟化石的形成过程。

The sediment acts as a protective layer, preventing the turtle's body from decaying completely.Over millions of years, the sediment continues to accumulate, and the weight of the sediment compresses the layers underneath. This pressure helps to preserve the turtle's body by turning it into a fossil. The minerals in the sediment gradually replace the organic material in theturtle's body, creating a replica of the original skeleton.Eventually, through geological processes such as erosion or tectonic activity, the layers of sediment containing the turtle fossil are uplifted and exposed. This can happen when mountains are formed or when the Earth's crust shifts.Once the fossil is exposed, it can be discovered by paleontologists or fossil hunters. They carefully excavate the fossil from the surrounding rock and transport it to a laboratory for further study and preservation.中文回答：乌龟化石的形成是一个非常有趣的过程，涉及到几个步骤。
