As a class assignment you have been asked to write a description of life cycle of the silkworm and the production of silk cloth.
Using the information in the diagram, write a description of the cycle.
选项
答案
The first diagram shows that there are four main stages in the life of the silkworm. First of all, eggs are produced by the moth and it takes ten days for each egg to become a silkworm larva that feeds on mulberry leaves. This stage lasts for up to six weeks until the larva produces a cocoon of silk thread around itself. After a period of about three weeks, the adult moths eventually emerge from these cocoons and the life cycle begins again. The cocoons are the raw material used for the production of silk cloth. Once selected, they are boiled in water and the threads can be separated in the unwinding stage. Each thread is between 300 and 900 metres long, which means they can be twisted together, dyed and then used to produce cloth in the weaving stage. Overall, the diagrams show that the cocoon stage of the silkworm can be used to produce silk cloth through a very simple process.
