Silkworms, the tiny creatures responsible for producing one of the most luxurious fabrics known to humanity, have captivated our interest for centuries. From their humble beginnings as eggs to their metamorphosis into silk-spinning moths, the life cycle of silkworms offers a wealth of intriguing insights. In this essay, we will delve into various aspects of silkworms, including their biology, economic significance, and cultural importance.First and foremost, let us explore the biology of silkworms. Silkworms, scientifically known as Bombyx mori, belong to the order Lepidoptera and are closely related to butterflies and moths. These remarkable creatures undergo a complete metamorphosis, consisting of four distinct stages: egg, larva (caterpillar), pupa (chrysalis), and adult moth. The entire life cycle typically spans around 6-8 weeks,although this can vary depending on factors such as temperature and food availability.The journey begins with the hatching of tiny silkworm eggs, each no larger than a pinhead. From these minuscule eggs emerge voracious caterpillars whose sole purpose is to feed and grow. Silkworms have a hearty appetite, consuming large quantities of mulberry leaves, their primary source of nourishment. As they feed, they undergo several molts, shedding their old skin to accommodate their increasing size.After reaching full maturity, the silkworms enter the pupal stage, where they encase themselves in a cocoon made of silk fibers produced by specialized glands. Inside the cocoon, profound transformations take place as the pupae undergo a remarkable process of tissue reorganization, culminating in the emergence of adult moths. However, in commercial silk production, the cocoons are harvested before the moths emerge to prevent damage to the silk fibers.Now, let us turn our attention to the economic significance of silkworms. Silk production has been an integral part of various cultures for millennia, prized for its lustrous appearance and luxurious feel. China, historically renowned as the birthplace of silk cultivation, remains the world's leading producer of silk.

剑桥雅思真题6—写作（Test 3 附高分范文）Writing Task 1You should spend about 20 minutes on this task.The diagrams below show the life cycle of the silkworm and the stages in the production of silk cloth.Summarise the information by selecting and reporting the main features, and make comparisons where relevant.Write at least 150 words.参考范文1：The given pictorials show the life cycle of the silkworm and also shows the processes of silk cloth productions.The life cycle of a silkworm begins from the eggs laid by the mother worm and from these eggs the silkworm larva are generated after 10 days. The silkworm larva usually eats leaf like mulberry leaf and completes the second stage of the life cycle in 4-6 weeks. In their third stage, they create silk thread shells and remain there for another 3 to 8 days and then create an oval cocoons. The cocoon-stage lasts for around 16 days and they become moth in the final stage. With time the moths become grown-up and recycle the processes again.The second picture describes the processes of the silk cloth production which has more than 5 stages. In the initial stage, the silk thread shells of the silk worm are selected and then boiled in the next stage. After boiling in water the threads are unwinded and they are usually 300 to 900 meter long. Then these are twisted and dried and finally those are weaved to silks. The twisting, drying, weaving and then drying again process is done more than once as per necessary to produce fine quality silks.参考范文2：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.参考范文3：The first diagram shows that there are four main stages in the life of the silkworm.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.The cocoons are the raw material used for the production of silk cloth. Once selected, they are boiled in the 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.Writing Task 2You should spend about 40 minutes on this task.Write about the following topic:Some people think visitors to other countries should imitate local custom and behaviors. Some people disagree, they think the host country should welcome culture different.Discuss the two views, and give your own opinion.Give reasons for your answer and include any relevant examples from your own knowledge or experience.Write at least 250 words.参考范文：Many people wonder what to do when they visit other countries. Some people think it is best for them to adopt the local customs. However, other people think it is best to follow the customs of their own countries. This is not an easy question to answer.Sometimes, visitors may do something that is common in their own countries, but immoral or even illegal according to the customs of the local country. For example, in certain countries, it is considered bad to show affection in public, like men and women kissing or holding hands. It may also be very bad for women to wear scanty clothing such as a short skirt or see-through blouse. In some countries it may also be illegal to drink alcohol.Adapting to the local customs can show respect. Wearing a suit and tie can show respect if that is what the people of the country wear at a meeting or formal event. Men will take their hat off or women will cover their heads to show respect when entering a "holy" place.However, many local people show their understanding if their visitors don’t follow their local customs or practices. They know their customs may be strange or difficult for foreign visitors to follow. They know foreigners may not break some of their rules on purpose.As we can see, there are many aspects to this question. I feel that visitors should follow the customs of the country if it shows respect to the local people or is required by law.。

The life cycle begins again from then on.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 stepsCambridge IELTS 6 Version: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. 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.《玻璃的再生》范文：As is displayed in the flow chart, the recycling process of glass is really a complex one.The overall process can be categorized into 3 stages. First, glass products in various forms are gathered in the Collection point, so that they are easily transported by special trucks or vans to the Cleaning plant, where they get sterilization by high-pressured water. There are three differentchannels in the Recycling plant, namely Brown, Green and Clear, which represent the colors of glass. After recycled in the furnace , glass products are melted into recycled liquid glass. Mixed with new liquid glass, the compound is finally moulded into solid glass, which, afterwards, will be sent to various customer supermarkets for selling. Thus, the glass will go to the customers for different purposes.Through a brief introduction of the circle of glass recycling, we come to realize that recycling plays a vital role in environmental protection and ecological preservation.water filter:The digram illustrates the complete process of water filtering . As can be seen from the flow chart, the gathering procedure of water purifying is similar to the water evaporation.The first step is to prepare a large container with several green plans and a small bottle on the middle of the bottom. Then, a piece of plastic sheet on the plane of the mouth of the bigger container. In order to prevent the plastic film from moving, four stones are placed on each edges respectively.After the preparation, the device can produce the clean water. Thanks to the sunlight shining, the vapor from the green plants rises up to the atmosphere and alters to liquid that accumulates on the lowest point of the plastic coating when it meets the cool air. Subsequently, the pure water drops into the bottom container directly, the pure water collection is accomplished via the principle of evaporation of green plants.《户外取水》范文：The chart describes how water is obtained outdoors.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.《房屋不同季节的构造》范文：As is displayed in the flow chart, the principles of insulation in cool and warm climate respectively differ to a large extent.As to the situation of cool climate, we adopt the high-angled roof in order to be nearly parallel with the direction of the sun so that the direct exposition to the heat of sun is lessened as much as we can. By this, the temperature of the material won’t fluctuate within a large range. Meanwhile, thermal building material could enhance the heat storage insulation, preventing outflow, thus reduction of heat.Adversely, in warm climate, reflective building material is indispensable with overhands for shade. The direction of the roof is almost vertical to the direction of the sun to lead to external insulation reflection. By this, ventilation would result in the removal of heat storage rather thanreduction.Through the different working principles of ventilation, we are fascinated by the masterpieces of modern science and technology.《超市建造地点选择》范文：As is unfolded in the map, Place M and N have their unique pros and cons as to the place for building the supermarket.First of all, Place N is located in the urban area of the G town, which may have more population and business. This advantage is incomparable with Place M. What’s more, Main road runs across the center area with convenience in traffic and logistics for the market afterwards. However, the place is equally far away from the neighborhood and the suburb area and cannot attract the residents in the outskirts.As a double-edged sword, Place M is more specifically customer-oriented. In spite of its comparably remote location with Place N, it would attract more customers in the outskirts, for they are reluctant to make a long trip for shopping. On the other hand, the train line nearby will also bring convenience in traffic to the urban -dwellers. Situated to the north-west of Place N, Place M is near the A and B Town with total population of 23 million, far outnumbering the overall population of D and E town, with 12 million.What’s worthy of being mentioned is that fierce competition in Place N and probable monopoly in Place M should also be taken into account when building the supermarket.《化肥的制作》范文：As is shown in the flow chart, the process of recycling organic waste to produce compost is really a complex one.The whole process can be categorized into five stages . First of all, prepare a plastic container which has four holes for ventilating the air. There is a rule when putting waste into the container, food at the bottom within 15 centimeters high, grass at the middle and newspaper at the top within 15 centimeters high altogether, in order to make a optimum (appropriate) environment for different bacteria细菌reproducing. In the following stage, we can witness nitrogen氮and water being put into the container. What's worth mentioning is that water is only added in a hot weather. Next, heat the waste and let the bacteria reproduce fastly, with which the organic waste can be decomposed and became garden fertiliser after 6 months. Subsequently, we can carry the compost out and move it to the garden, thus a new recycling can begin.In conclusion, using this way to turn the organic waste into garden fertiliser 化肥is environmentally friendly. By enlarging the number orvolume of the container, we can dispose more waste at the same time.。

These voracious creatures embark on a rapid growth phase, consuming vast quantities of mulberry leaves, the primary food source for silkworms.As the silkworms grow, they undergo a series of molts, shedding their skin to accommodate their expanding size. This process is carefully monitored by the silkworm rearers, who ensure that the worms are provided with the optimal environmental conditions,including temperature, humidity, and air circulation, to support their development.Once the silkworms have reached their full size, they begin the remarkable process of spinning their cocoons. This intricate task is a marvel of natural engineering, as the silkworms extrude a continuous filament of silk from specialized glands, meticulously weaving it into a protective shell around themselves. The resulting cocoons are a sight to behold, with their delicate, shimmering strands forming intricate patterns that have captivated artisans and textile enthusiasts for centuries.The silkworm rearing process does not end with the cocoon formation, however. The next step involves carefully harvesting the cocoons, a task that requires skill and precision. The cocoons must be carefully sorted, graded, and processed to extract the valuable silk fibers. This process typically involves boiling the cocoons to dissolve the sticky sericin proteins that hold the silk fibers together, allowing the individual strands to be unwound and spun into yarn.The quality of the silk produced is heavily dependent on the care and attention given to the silkworms throughout their lifecycle. Factors such as the health and nutrition of the worms, the cleanliness of their environment, and the timing of the harvesting process all play a crucial role in determining the final quality and luster of the silk.One of the most remarkable aspects of silkworm rearing is the level of manual labor and attention to detail required. The process is highly labor-intensive, with silkworm rearers often working long hours to ensure the well-being of their charges. From the delicate task of feeding the worms to the meticulous handling of the cocoons, every step in the process requires a deep understanding of the silkworm's needs and the ability to respond quickly to any changes in their environment.Despite the challenges, the rewards of silkworm rearing can be substantial. The silk produced is renowned for its exceptional quality, with its lustrous sheen, soft texture, and durability making it a highly sought-after material in the fashion and textile industries.
