仅用一种语言的

In fact, algebra is a simple language, used to create mathematical models of real-world situations and to handle problems that we can't solve using just arithmetic.

实际上，代数是一种简单的语言，用于对现实世界建立数学模型，而且还用于处理一些仅用算术无法解决的问题。

I know this for a fact that I am still being out of my element for english and,there may be a possiblility in overleaping myself with ambition,but,it is a dream that to be well versed in another language in 5 years subsequent to me of 30-year-old which I have been haunting,just years ahead of schedule so that it fails to be disillusioned.

我知道一个事实如此，我仍然是我的元素进行英语和，可能有一个跨越式的野心自己possiblility，但它是一个梦想，要在5年内也用另一种语言后，我精通30岁，我一直困扰，仅比预定时间提早，使它不能要失望了。

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。
