I have been a amateur astronomer to observe stars through telescope.

我以前是业余的天文家，用望远镜观察星星。

In the term of unloading and opposite side loading, let the stress-strain curve have the same form of skeleton curve, the curve uses the last unloading point as its starting point, and uses soil's ultimate stress level as its asymptote. Then the hysteretic curve is constructed.

在卸载和反向加载时，采用与骨架曲线相同的函数形式，并以前一次卸载开始点作为起点，以土体的极限应力水平作为渐近线，构造出土体动力本构模型的滞回曲线。

To make our approach to be practical, we also discuss the asymptotic expansion of the operator in chapter 6 which is based on the non-abelian Stokes theorem.

但是由于格点上的算符是path-order变量的乘积，并且其构成非常复杂，按照正常的方式展开实际上是不可能的，为了使我们的算法实际可行，本文接着讨论了格点上算符的渐近展开问题，并且给出了基于non-abelStokes定理的方法，这种方法克服了以前各种办法的缺点，并且简单可行，适用于任意的Wilson算符。

The person I go to meet may be changed in his feelings towards me; or he may retain all the old feeling until the moment of seeing me, and then lose it in a breath at sight of my poor wan face, for I was called a pretty girl, Mr. Talboys, when I sailed for Sydney, fifteen years ago; or he may be so changed by the world as to have grown selfish and mercenary, and he may welcome me for the sake of my fifteen years' savings.

我回去和他相会的人，也许对我变了心；或者，他也许保留着全部旧日的感情，直到看见我的那一刻，然后一看见我那憔悴苍白的脸，转瞬之间便丧失了那份感情，因为，托尔博伊斯先生，十五年以前，我坐船去悉尼时，我是被称为俊俏姑娘的；或者，他也许被世事大大地改变了，变得自私自利、唯利是图，或许他欢迎我就为了我那十五年的积蓄。

He used to be a popular entertainer, but somehow, he is now at a discount.

以前他是个走红的艺人，但现在不知怎么不受欢迎了。

The house in which we lived sold at a high price.

那幢以前我们住过的房子卖得很高的价钱。

Simulation results show that our model converges at a faster rate than those of previous researchers.

数值模拟实验表明，与以前的研究者提出的模型相比，新模型的收敛速度更快。

Here is a situation that at least a few people have run into before.

这里是一个，至少有几个人遇到了以前的情况。

Now she teaches at business school, is a venture capitalist and sheds fewer tears.

如今，她在商学院教书，同时还是一位风险资本家，现在掉的眼泪比以前少了。

I must finish the work by tomorrow at all costs.

我无论如何必须在明天以前完成工作。

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

屈膝跪下。。。下跪祈祷
