声调不仅在现代汉语占有极重要的地位，就连在古音中也一样，古时汉语的声调有多少类，自来言人人殊，纷纭无定。中国传统音韵学上一向所谓的“四声”，都是声调分为把声调分为“平”、“上”、“去”、“入”四类，这情形至少在五世纪前就已经存在。

Tones play a very important role not only in modern Chinese, but also in ancient Chinese. There are many different kinds of tones in ancient Chinese. The so-called “four tones” in traditional Chinese phonology are divided into four types of tones: “ping”, “shang”, “go”, and “ent”. This situation has existed at least before the fifth century.

形状是一物体或其外部边界、轮廓及其表面所组成的，和物体的其他特性（如颜色、纹理、材料组成等）无关。形状也可以是由边或曲线或以上两种东西的结合来形成的封闭空间。

A shape is composed of an object or its outer boundary, contour and surface, and has nothing to do with other characteristics of the object (such as color, texture, material composition, etc.). The shape can also be a closed space formed by a side or a curve or a combination of the above two things.
