Passage 3 (20%) Autumn Sunset The sun sets on some retired meadow, where no house is visible, with all the glory and splendour that it lavishes on cities, and, perchance, as it has never set before,--where there is but a solitary marsh-hawk to have his wings gilded by it, or only a musquash looks out from his cabin, and there is some little black-veined brook in the midst of the marsh, just beginning to meander, winding slowly round a decaying stump.

Elysium：极乐世界译文：秋天的日落幽静的牧场上，看不到房屋，太阳落山了，一如城市里日落时那般尽情挥洒，光芒四射，灿烂夺目，恐怕还与城中落日有所不同/以前还从未像这样落山过，因为在牧场上落日的余辉只在孤零零一只沼泽地苍鹰的翅膀镀上一层金色，也只有一只麝鼠从他的小木屋里向外张望，沼泽中几脉黑色的小溪正开始蜿蜒，绕着一个正慢慢腐烂的树桩慢慢地流淌着。

Methods 160 cases of ametropic amblyopic children,aged 4～7 years,were selected based on mydriatic retinoscopy and eye tests amony amblyopic children screened from 2000 to 2006,including 78 males and 82 famales.

对2000～2006年以来我院门诊的4～7岁屈光不正患者，通过散瞳验光及试镜，筛选出 160例（320眼）屈光不正性弱视患者，男78例（156眼），女82例（164眼）。

According to Zhang Zhengdong's description (Zhang Zhengdong: p320) of Myrna Delson-Karan's idea, in educational evaluation, the following items may be taken into consideration for the evaluation of a teacher of second language teaching.

据张正东的描述（张正东： p320 ）关于myrna delson - karan这的思路，在教育评价中，下列项目，可考虑为评价一名教师的第二语言教学。

Breakthrough of the Gaussian" as a positive N Gon's law "in ruler can only be a" positive 3,5,17,257,65537 Edge-shaped "conclusion.

突破了高斯"作正 N 边形定律"中尺规只能作"正3、5、17、257、65537边形"定论。

Today, in public, with 1: N --1 Framework Law that is the same geometric method demonstration, completed "as being seven, nine, 11, 13, 17-gon,""made positive N -Gon."

今天，当众，用1： N —1框架法即同一种几何方法演示、完成了"作正七、九、十一、十三、十七边形"，"作正 N 边形"。

It happened that an old goat and his wife were browsing in the neighbourhood, and, as the king and queen sat there, the nanny goat came to the well's brink and peering over saw some lovely green leaves that sprang in tender shoots out of the side of the well.

这时，正好有一头老山羊和它的老伴儿在附近吃草。国王和王后正坐在那儿休息时，母山羊也来到了井边，朝井里张望了一下，看到几片嫩绿的叶子正随着柔缓的水流在井壁旁摆动。

The baseline separation of 9 neutral compounds (thiourea, benzene, toluene, ethyl benzene, n-propylbenzene, naphthalene, n-butylbenzene, fluorene and anthracene) and 7 acidic, basic and neutral compounds (thiourea, o-aminophenol, phenol, benzene, o-methylaniline,α-naphthylamine, 2,4-dichloroaniline) can be obtained under optimized capillary electrochromatographic conditions.

在该均相硅胶基质整体柱上成功地分离了9种中性物质(硫脲、苯、甲苯、乙基苯、正丙苯、萘、正丁基苯、芴和蒽)以及7种中性、酸性和碱性物质(硫脲、邻氨基酚、苯酚、苯、邻甲苯胺、α-萘胺和2，4-二氯苯胺)。

But that's why the government is developing infrastructure, education and a nascent social safety net, he says.

但正因为此，中国政府正发展基础设施、教育和初步构建的社会保障体系，他表示。

The first kind is 0-equation model. It only includes mass and momentum conservation equations. Great progresses have been made in improving this model. It has successfully been applied to many natural rivers with complicated boundary geometry. The second kind is κ-ε model. The κ equation and ε equation are needed, besides mass and momentum conservation equations. Many researchers have studied the depth-averaged mathematical models of turbulence in recent years. However, the models were used mostly in regular artificial canals or natural water areas with simple boundaries.

对于宽浅型河流，采用深度平均法进行流场计算时，用得较多的有两类模型：一类是不增加任何脉动量的偏微分方程的模型，这类模型已在适体坐标下运用得较多且较成功；另一类是κ-ε二方程模型，它是近几十年来广泛应用的一类湍流模型，并发展了许多具体的形式，但大多数只对顺直河道进行了研究，对弯曲较大的河道研究不多，本文运用适体坐标，采用正交交错网格及非正交交错网格，把此模型运用到了弯曲较大的河段及具有汇流的河段，取得了较大的成功。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。

Go down on one's knees;kneel down
