When electron accelerates, its charge quantity won't change, as a result, its electromagnetic mass is constant, and the electromagnetic mass won't satisfy Lorentz transformation,thus, there is obvious inconsonance if we treat electromagnetic mass as a part of the gravity mass ---- as long as we insist the idea that the charge quantity of any electron is a constant.

当电子加速运动的时候，其电量是不会改变，所以其电磁质量不会发生改变，电磁质量不满足Lorentz transformation，因此把电磁质量作为引力质量的一部分存在着不协调性——只要维持电子电荷值不变的观念，这个问题不管怎么也解释不通。

The fact proves , the road that expends limited natural resources incontinently to exchange economy to develop and the road that are cost to build base of the sources of energy with development of estate of sacrificial environment etc all go be illogical .

事实证实，无节制地耗费有限的资源去换取经济发展的道路和以牺牲环境及其他产业发展为代价建设能源基地的道路均走不通。

This was a machine, a sinister band of inhuman robots inscrutably keeping the symbol of freedom for themselves, to be used for their own dark ends.

这是一个机器，一个由不通人情机械人组成的强悍队伍，莫测高深地把自由的标志留给他们自己黑暗目的所用。

Irene : I don't understand it either. It's your company's loss.

Orson: I don't know why either one of them wants to work for that jackass.

我想不通为什么他俩都要为这个蠢人工作。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
