范文

The first diagram shows the life cycle of the silkworm that divides into four periods. And the second illustrates the processing of cloth making in stages.

From the first diagram, initially, eggs are laid by the moth and it takes ten days for each egg to hatch out. Then the larva living on the mulberry leaves also live by the leaves. Subsequently, after utmost six weeks, the larva spins silk threads to form a cocoon. After a period of around a week, in the fourth stage the silk threads are rolled into a cocoon. Finally, ten days later, a moth emerges from the cocoon and the life cycle restarts once more.

From the second diagram，there are five main stages in the cloth making: selecting, boiling, unwinding, twisting and weaving（also dying included）. Once selected, sounded cocoons are heated in hot water until they start to unwind. The ideal condition is that the thread can be between 300 and 900 meters long, which shall be twisted together for the weaving and dying stages at last.

第一張圖表顯示了蠶的生命周期，分為四個(gè)時(shí)期。第二章闡述了布料制作的分階段過(guò)程。

從第一張圖來(lái)看，最初，蟲(chóng)卵是由蛾產(chǎn)卵的，每個(gè)蟲(chóng)卵需要10天才能孵化出來(lái)。然后生活在桑葉上的幼蟲(chóng)也靠桑葉生活。隨后，在最長(zhǎng)六周后，幼蟲(chóng)會(huì)旋轉(zhuǎn)絲線形成繭。大約一周后，在第四階段，絲線被卷成繭。最后，十天后，一只蛾從繭中出現(xiàn)，生命周期再次重新開(kāi)始。

從第二張圖來(lái)看，織物的制作主要有五個(gè)階段：選、煮、放、捻和織造（也包括染色）。一旦選定，發(fā)出聲音的蠶繭將在熱水中加熱，直到它們開(kāi)始展開(kāi)。理想的情況是，線的長(zhǎng)度可以在300到900米之間，最后在織造和染色階段將其擰在一起。
