We often abbreviate words by dropping the endings.

缩写词一般是不要末尾的那一部分。

Similarly, the word " carbohydrates" can be abbreviated by saying " carbs" (carbs).

同样，“carbohydrates”这个词可以缩写为“carbs”（碳水化合物）。

Sometimes an entire word is abbreviated by just one letter, and that letter has a period mark after it.

有时整个单词仅由一个字母缩写，并且该字母后有一个句号。
