Unit 4 Roots about “Drawing”, “Cutting”“Parting” and “Dividing”
Lecture 2
Roots about “Cutting”
1. Warming-up 课程准备
The unit begins with a very popular theme song of a Chinese TV series. One line of the lyrics is actually from one of Li Bai’s poems.
Li Bai was the great poet of the Tang Dynasty. That famous line is “抽刀断水水更流，举杯消愁愁更愁。

” It can be translated like this: When you draw your sword to strive to cut the water, it flows more rapidly, and when you drink your wine to try to lessen your grief, you get more grief. The four lectures in this unit will dwell on the roots respectively related to the meanings of drawing, cutting, parting and dividing. And the second one is on the root “sect” or “seg”, which means “to divide”or “to cut”.
