Model Answer 1

The provided illustrations delineate the life cycle of the silkworm, alongside the multiple phases entailed in fabricating silk cloth.


Commencing with an overarching view, the silkworm's life cycle unfolds through four critical stages, beginning with the hatching of larvae from eggs, which subsequently mature by feasting on mulberry leaves. Post nourishment, they spin silk threads to form protective cocoons, wherein they transition into moths. Concurrently, the production of silk cloth involves a sequence of meticulous steps, starting with the selection of suitable cocoons, followed by boiling, unwinding the silk threads, and culminating in the twisting, dyeing, and weaving of the threads into silk fabric.


Delving into particulars, the life cycle of the silkworm initiates with the laying of eggs by the moth, from which larvae emerge after approximately 10 days. In a span of 4 to 6 weeks, these larvae voraciously consume mulberry leaves, a process pivotal to their growth. Subsequently, they secrete silk threads to craft their cocoons, residing inside for 3 to 8 days. The cocoon phase persists for around 16 days, culminating in the emergence of a fully formed moth, thus perpetuating the cycle.


The journey from cocoon to cloth commences with the selection of cocoons, which are then boiled to facilitate the unraveling of silk threads, typically extending between 300 to 900 meters. These threads are then twisted, which is a precursor to the dyeing process. Finally, the dyed silk is expertly woven to produce silk cloth, with the twisting, dyeing, and weaving processes potentially repeated to ensure the creation of silk of the highest caliber.

Model Answer 2

The provided diagrams encapsulate the life cycle of the silkworm and the subsequent stages in silk cloth production.


At a glance, the life cycle of the silkworm is depicted as a cyclical process, beginning with egg-laying and culminating in the emergence of a moth, which then perpetuates the cycle. Concurrently, the silk cloth manufacturing sequence is portrayed as a linear progression from cocoon selection to the final weaving stage.


Focusing on the silkworm's life cycle, it commences when the moth deposits its eggs, which, after a brief ten-day period, yield silkworm larvae. These larvae undergo a period of intense growth over 4-6 weeks, sustained by mulberry leaves. This voracious consumption is a precursor to the next phase, where larvae secrete silk threads, forming cocoons. The encapsulated silkworms undergo a transformative 3-8 day period within their silken shells, eventually maturing into cocoons that endure for 16 days before the cycle reaches fruition with the birth of a new moth.


In parallel, silk cloth production is initiated by selecting robust cocoons, which are then boiled to loosen the silk threads. These threads, often spanning 300-900 meters in length, are meticulously unwound. Post-unwinding, a twisting process is applied to the threads, which are subsequently dyed. The final act of weaving transforms these threads into the coveted silk cloth. Each step, from boiling to weaving, is performed with precision, ensuring the transformation of the silkworm’s cocoon into luxurious silk.

Model Answer 3

The provided visual representations delineate the life cycle of the silkworm and the sequential procedures involved in fabricating silk cloth.


An overview of these schematics reveals that the silkworm undergoes a transformation from eggs to larva, and then to a cocoon, which is pivotal for silk creation. Concurrently, the production of silk cloth entails a systematic process starting from the cocoon and culminating in the dying of the woven material.


Delving into specifics, the initial phase in the life cycle of the silkworm commences with the deposition of eggs on mulberry leaves, which, after a 10-day period, hatch into larvae. The larvae feed on the mulberry leaves for approximately 4 to 6 weeks, during which they spin silk threads to form protective cocoons. These cocoons are then set aside for 16 days, allowing for the metamorphosis of the larva into a moth.


In parallel, the production of silk cloth begins with the selection of appropriate cocoons, which are submerged in boiling water to loosen the silk threads. Subsequently, these threads are carefully unwound, producing lengths ranging from 300 to 900 meters. The unwound silk is then twisted, a prerequisite for weaving. The weave is then subject to the dying process, allowing for a range of colors to be imparted onto the silk cloth, marking the final stage of production.

The illustration delineates the intriguing progression of the silkworm's life cycle and the intricate stages involved in the manufacturing of silk cloth.


Commencing with an overview, the life cycle of the silkworm unfolds through four critical phases, initiated by the moth's egg-laying and culminating with the cocoon's creation, from which a new moth will emerge. Correspondingly, the transformation of the cocoon into luxurious silk cloth involves a meticulous process of selection, boiling, unwinding, twisting, and dyeing.


Delving into specifics, the silkworm begins its journey enveloped within the confines of an egg, placed tenderly upon a mulberry leaf, taking a mere 10 days to hatch. The larvae emerge with an insatiable appetite, consuming mulberry leaves for 4-6 weeks, during which they meticulously spin silk threads, encasing themselves in a protective shell. This stage is transitory, lasting between 3-8 days, ultimately sculpting the iconic cocoon. After a 16-day metamorphosis, the cycle reaches its zenith as a moth emerges, ready to perpetuate the species' existence.


The production of silk cloth is equally systematic, starting with the selection of the finest cocoons, which are then submerged in boiling water. The unraveling of the cocoon threads yields an astonishing length of 300-900 meters of silk. These lengthy strands undergo a twisting transformation, aligning their fibers for strength, followed by a dyeing process for aesthetic value. The final weave integrates these threads into the soft, lustrous fabric known globally as silk cloth, completing the cycle from cocoon to textile.
