我不太记得以前是否去过花莲，如果有的话，应该也是很小的时候。

Low-lying areas have been evacuated and people have been sent to higher ground.

地势低洼区域的人已经疏散，被送往地势较高的地方。

The statistical simulation analysis method is effective to deal with space- time heterogeneity of earthquakes and risk regions, after 105 count of the va lues of simulating random prediction probability have been got, the objective result s have been got by comparing between the simulation prediction average probabili ty and the practice prediction average probability.

由于统计模拟的方法有效地处理了地震和危险区的时空不均匀性，并且得到经运算105次的统计模拟随机预报概率，将其与实际预报平均概率比较，得到较为客观的结果。

The appearance and subsequent diversification of biomineralization in Metazoa have long been a puzzle for geologists and palaeobiologists. Various hypotheses have been proposed, but none seems to be satisfying.

后生动物骨骼化是地质历史时期最重要的生命创新事件之一，后生动物是何时，以何种方式形成了最早的骨骼，骨骼化的动因是什么，一直是地学界难解之迷。

Results In 1980, the filariasis have been basic eliminated in Yangshan County, the microfilaria rate have been come down to 0.120% from 4.35% before control.

结果经过反复查治，阳山县微丝蚴率从防治前的4.35％降至0.12％，1980年达到基本消除丝虫病标准，1996年经广东省卫生厅组织评审，确认全县范围已阻断丝虫病传播，达到了消除丝虫病标准。

We are not denying that he has done the interview with Le Monde but they are saying there must have been some mistake or something like that because you know, if 140 people have been killed this Monday, well it is news to us.

我们不否认他接受了《解放报》的采访，但是他们说的一定有一些错误或是误会之类的东西，因为你知道，如果140人本周一被杀的话，这对我们来说是一个新闻。

If I had not been born Napoleon, I would have liked to have been born Alexa nder.

如果今天我不是拿破仑的话，我想成为亚历山大。

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。

"Have you ever been to that nature park "——" Yes, I have been there."

"你到那天然公园去过吗"——"是的，我去过。"

The topographical parameters have been analyzed by taking into account the thermal effect during the friction process. As the results, three kinds of typical topographical features have been observed for the worn surfaces of C G iron with various P content. Namely, C G iron with 0.05% P, 1.30% P, and 0.70% P show worn surfaces characterized by groove ridge, peak pits and their combined topography. The C G iron specimen with peak pits type worn surface topography showes the lowest wear rate and highest friction coefficient, while that with groove ridge type worn surface topography shows the highest wear rate and lowest friction coefficient. The groove ridge type worn surface has a relatively large value of surface height deviation and void volume ratio and negative large value of skewness, which is contrary to the peak pits topography.

结果表明：度销磨损表面主要呈现犁沟型、孤岛型及二者的混合型3种形貌特征，其中具有孤岛型磨损表面形貌特征的试样的摩擦系数较高，磨损率较低；而具有犁沟型磨损表面形貌特征的试样的摩擦系数最低，磨损率最高，分析表面形貌参数发现：犁沟型表面形貌具有最大的表面高度偏差和表面空隙率及高负值的表面高度分布参数；而孤岛型表面形貌的表面高度偏差和表面空隙率最小，表面高度分布参数为高正值。

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。
