剑6 Test3 task1 写作范文-“The diagrams ”

　题目：The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.

　　The information given by the flow charts is about how a silkworm reproduces itself and the detailed steps in the production of silk cloth.

　　The first diagram shows that the life cycle of the silkworm involves four main stages. First of all, eggs are deposited by the moth and it takes ten days for the eggs to become silkworm larvae that feed on mulberry leaves. The step lasts for around six weeks until the larvae turn into cocoons by spitting lots of threads around themselves. Finally, after about three weeks, adult moths break the cocoons, and a new life cycle begins again.

　　According to the second chart, the whole process of silk cloth production includes the following stages. In the first step, the cocoons are selected and they will be boiled in water. Next, the cocoons are unwound into 300-900-meter threads. After that, the threads are twisted together and dyed. At the final stage, we can weave up them and dye the cloth once again.
