Title 1: glass recycling flow chart.
Model essay 1:
This chart illustrates the recycling process of glass bottles. The whole process is a cycle, which can be divided into three main stages.
In the first stage, used bottles are collected at a collection point and ready to be transported by truck. The second stage starts from a cleaning factory, where the recycled bottles are divided into green, brown and transparent according to color and washed with high-pressure water. After cleaning, the bottles are transported to the glass factory, where they are cut into glass pieces and then poured into the furnace. After heating in the furnace, the broken glass melts into liquid and flows into the glass mold. Here, glass liquid from other sources is added and the molding process is carried out. In the final stage, the new empty bottle is filled with liquid, then packaged and sent to the supermarket, waiting for consumers to choose. At this point, a cycle has been completed and a new cycle is about to begin.
Topic 2: the life history of silkworms and the flow chart of making silk garments.
Model essay 2:
The chart outlines the main stages of silk life cycle and the making process of silk cloth. The relationship between two graphs comes from this graph. Cocoon is a necessary raw material for silk production.
Describe the process 1 In the first stage, eggs are produced by moths, and it takes ten days for each egg to become a silkworm larva and feed on mulberry leaves. This stage lasts as long as six weeks until the larva produces a silk cocoon around it. After about three weeks, adult moths finally emerge from these cocoons and their life cycle begins again.
Description Process 2 Speaking of silk production, once the cocoons are selected, they are boiled in water, and the threads can be separated in the unwinding stage. Each thread is 300 to 900 meters long, which means that they can be twisted together, dyed and then used to produce cloth in the weaving stage.
Generally speaking, these charts show that silk in cocoon stage can be used to produce silk through a very simple process.
