I spent a year dueling for first chair on tenor sax with Larry McDougal, who looked as if he should have played backup for Buddy Holly, the rocker who died tragically in a bad-weather plane crash in 1959 along with two other big stars, the Big Bopper and seventeen-year-old Richie Valens.

有一年时间，我和拉里。麦克道戈尔积极争夺次中音萨克斯管的首席。麦克道戈尔神气的不得了，似乎觉得自己该为摇滚乐手巴迪。霍利伴奏。1959年，在一次气候恶劣的飞行中，霍利不幸机毁人亡，同时遇难的还有另外两位大明星，一位是比格。波帕，一位是17岁的里奇。

First, they must be brought together by fate, people live whole life, you can hit many times wonderful coincidence, but it can only be met once elegant fate, coincidence is a gust, the inevitable fate is the root line, and that a Line lingering too through the mountains and rivers, slim and fragile too seem to have, it seems that there is no, a man and a woman, in the middle as long as it is involved, even if it ends of the earth can also meet by chance.

首先，他们一定要有缘份，人活一生一世，可以撞上无数次奇妙的巧合，却只能遇上一次瑰丽的缘份，偶然的巧合是阵风，必然的缘份是根线，那一根线绵长得穿山越岭，细弱得若有若无，一男一女，中间只要有它牵连，哪怕天涯海角，也能萍水相逢。

Writing is essential to the subject of language exam, I once bought a "good good word sentence paragraph good," I seem to be obsessed with it, because it is really exciting, time for some time, had a Language examinations, Xie Jing is the title essay, Kazakhstan over the past two days I can not look at the beautiful little statement, more or less to master a number of ways, it was handy, such as "Hangyunliushui", a word from the nib of a child slipped out, it turned out, this I am writing to obtain good results.

作文是语文考试必不可少的题目，有一次，我买了一本《好词好句好段》，我似乎迷上了它，因为它实在太精彩了，读了一段时间后，进行了一次语文考试，作文题是写景，哈这两天我可没少看优美语句，多好多少掌握了一些办法，写起来得心应手，如&行云流水&，文字一个一个从笔尖儿溜出来，果然，这篇作文我取得了不错的成绩。

The main contents are as follows:Firstly, starting with the general situation of soil erosion and the harms caused by it, the causes leading to the local soil erosion problem are analyzed comprehensively in the paper. And connecting with the measures taking place, sticking points towards the career of soil and water conservation are expatiated upon.Secondly, Back-Propagation Neural Network, One of Artificial Neural Network is used to set up a modal about the connection of the soil erosion modulus and seven factors impacts on it, such as, rainfall, rainfall largest intensity in 30 minutes, runoff coefficient, vegetation cover percent, rate of granule, rate of physical viscidity-clay, the rate of organic matter. Through the comparison with linear regression model, the second regression model, the Chinese Soil Loss Equation, it illustrated that BP Neural Network modal is more accurate than the other three modals in forecasting the mount of soil erosion, and the BP Neural Network will have some applicability in forecasting in soil erosion.

本文以霍山县作为皖西大别山区的典型区域，主要研究了以下内容：(1)从介绍霍山县土壤侵蚀状况以及所造成的危害入手，全面分析了导致当地土壤侵蚀发生的原因，并结合当地采取的水土保持相关措施，阐述了当地水土保持工作的症结所在；(2)结合上土市水土保持试验站多年实测资料和2005年实验资料，应用BP神经网络理论，建立了次降雨土壤侵蚀量与次降雨量、最大30min雨强、径流系数、植被覆盖度等因子之间关系的模型，并通过BP神经网络的预测模型与一次回归模型、二次回归模型、CSLE模型之间的对比分析，说明了建立的BP神经网络模型在土壤侵蚀预测可以取得较回归模型和CSLE模型更高的精度，也说明了BP神经网络理论在土壤侵蚀预报中具有一定的适用性。

The wind come my side again at this moment, then the white fox go to me from the back of tree.

在一次偷偷跑出去摘桑葚后，由于贪吃，我落在了伙伴的后面，随着夜幕的降临，我迷路了，夜色中，那阵小小的风再一次出现了，在我周围盘旋一阵后，绕到了一棵大树的后面，接着从大树后面出来一只白色的狐狸。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
