had been built where the park was, and the original building areas were converted into industry buildings such as parks, parking lots and swimming pools. The most obvious changes were that the former grasslands disappeared, being cinemas in the southwest, shops in the southeast, and houses in the northeast. On the north side, although the sea was still there, a wharf was built in it so people could travel more easily by sea.Finally, although there was still a cross road in the city, the horizontal road was moved to the south. By doing so, industry buildings and houses could be left more places to develop. Anyway, the city had experienced tremendous changes throughout the 57year period.流程圖(C6T3W1)The first diagram shows that there are four main stages in the life of the silk worm.First of all, eggs are produced by the moth and it takes ten days for each egg to bee 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.
