The given diagrams illustrate the life process of the silkworm and the phases in the manufacture of silk cloth.

Overall, the life cycle is a process that contains four cyclical phases, beginning with the laying of eggs and ending with the birth of a new moth from a cocoon. On contrary, the production of silk is a linear process which involves 6 main stages.

To begin with, the moth gives birth to its eggs and it takes 10 days for the eggs to hatch into silkworm larvae that live on mulberry leaves. After another 4 to 6 weeks, the silkworm will construct a cocoon from silk thread, which takes 3 to 8 days. They stay there for 16 days, subsequently emerging as moths and the life cycle begins again.

The first stage in silk production is the selection of cocoons and these are then boiled. After boiling, the silk thread will be unwound to a thread between 300 and 900 meters in length. Finally, the thread will be twisted and weaved into cloth before being dyed.


With the prevalence of health care in a great number of countries, people start to concern whether medical institutions should be run by the government rather than profit-oriented companies. Personally, I firmly contend that the disadvantages of private institutions outweigh the advantages.

On one hand, private institutions do have their bright sides. Firstly, private institutions are more likely to offer better services and are more equipped to offer personalized care. They often have upscale amenities that make patients feel more like nice hotels than hospitals. Also, doctor-to-patient ratios are usually satisfying in private institutions. For instance, in my country, thanks to the high doctor-to-patient ratio, doctors in private hospitals are usually more patient and are willing to spend more time communicating with patients. Secondly, some institutions may specialize in certain fields, whether it be chirurgery and ophthalmology, which enables them to provide the patients with more effective treatments.
