So how does the cactus obtain such tenacious vitality? Please read paragraphs 2 to 4 of the text again and see what you know from the introduction to the root system and stem flesh of the cactus?

Its root system is well-developed and highly absorbent, and its stems not only have a strong ability to absorb water, but can also store water. This unique structure is formed to adapt to the arid and difficult living environment of the desert.

In order to reduce water evaporation, the leaves of the cactus are severely degraded. Some people have done experiments where the cactus can still survive without water for six consecutive years. Since the leaves cannot perform photosynthesis, its stem takes on this important task, performs photosynthesis, and supplies nutrients to the entire plant.

After reading these three paragraphs, we know that cactus can not only be used as a raw material for sugar refining, wine making, feed, fuel, dyes, and building materials, but it can also prevent soil erosion and be used for ornamental purposes. It is indeed very useful and has brought many benefits to our lives.

What does the author think of such a tenacious and versatile cactus? Ask the students and the teacher to read the last natural paragraph of the text together. Think about it, how many meanings are written in this paragraph?

With its tenacious and vigorous vitality, cactus grows in the harshest environment of heat and drought, and has contributed many valuable things to people. Although it is covered with thorns and does not look amazing, its appearance cannot compare with tall and straight trees and swaying exotic flowers. However, the cactus’ perseverance and tenacity to adapt to the harsh environment and its spirit of silent dedication are actually a kind of Unique beauty. It can be said that cactus is a model that only talks about giving and not asking for anything!
