雅思小作文真题范文：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.

　　Another Sample：

　　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 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.
