  雅思写作高分范文之蚕丝制作
  As is displayed in the first diagram, the life cycle of the silkworm can be categorized into 4 main stages. First, the life of the silkworm starts from eggs propagated by the moth, and it takes 10 days for each egg to become a silkworm larva that feeds on mulberry leaves. Silkworm larva continues to grow in 4 to 6 weeks, then wrapping itself with silk thread to construct a cocoon in the next 3 to 8 weeks. A moth can be produced from the cocoon in 16 days. The life cycle begins again from then on.
  Focusing on the second diagram, it illustrates the 5 main steps of the procedure of producing silk cloth. Well generated cocoons will be selected firstly. Before the silk thread can be unwound, cocoons have to be boiled in hot water. One cocoon can produce approximately 300 to 900 metres of silk thread. The unwound thread will be dyed afterwards to be weaved into silk cloth.
  Overall, the two diagrams reveal the stage of producing cocoons in the life cycle of the silkworm can be used to make silk cloth through 5 simple steps.
  CambridgeIELTS 6 Version:
  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.
  According to the figure, the first step of obtaining water outdoors is to find a hole with green plants on its bottom. Next, remove the green plants in the middle and put a container there. Then, cover the hole with a plastic sheet and place two stones on both ends of it to secure its position. A third stone is laid on the middle of the plastic sheet so that the middle part is also the lowest part.
  When the sun shines on the green plants in the hole, water evaporates from these plants. The vapor rises up and then cools down to form. water drops on the plastic sheet. When there is more and more water, it flows along the sheet to accumulate on the lowest part. Finally, water falls down into the container directly under the middle stone.
  Thus, water is collected successfully through evaporation from green plants.
  Through the different working principles of ventilation, we are fascinated by the masterpieces of modern science and technology.
