The true origins of silk fabric will likely never be known. The best that can be done is【小题1】 (search) the archaeological (考古) record for its earliest traces. A silkworm cocoon (茧) was discovered at a site in China 【小题2】 (date) to 5,000-3,000 BCE. Those【小题3】found it thought that the cocoon had been cut open【小题4】 (deliberate).

This seems unlikely to have been done if the cocoon was to be used to produce silk 【小题5】cutting the cocoon reduces the length of the silk fibres. Silkworm larvae (幼虫) have been, and still 【小题6】 (eat) in several countries, so it may be that this example was used for food rather than fashion.The【小题7】 (old) examples of silk fabric that still exist were discovered in Qianshanyang from 2,700 BCE. These【小题8】 (part) of threads and ribbons show how threads of silk were woven at【小题9】 early stage. Discoveries of artefact (人工制品) 【小题10】 (use) in spinning and weaving also point to an early development of silk fabrics in China.

The official medals of the Beijing 2022 Olympic and Paralympic Winter Games were displayed on October 26^th. The organizing committee introduced the medals—called tong xin, 【小题1】 means togetherness that day.

The medals are inspired by yu bi, a Chinese jade artifact 【小题2】 (date) back 5,000 years. A total of five of this kind of jade 【小题3】 (unearth) from a tomb up to now.

Each medal has carvings of the Olympic rings on one side. The rings represent the pursuit of unity and harmony, and they also represent the Olympic 【小题4】 (value) of solidarity and inclusiveness. Carvings of cloud patterns, 【小题5】 element used on the torch of the 2008 Beijing Summer Olympics, snowflakes and ice markings fill the outer rings. The 【小题6】 side of the medals has the Beijing 2022 emblem at the center. 【小题7】 (visual), it looks quite plain at first glance, while details such as the carving of clouds and snowflake patterns as well as the uneven surface have made it 【小题8】 (special) than expected, according to the committee.

Gaining 【小题9】 (inspire) from jade for a second time honors the Chinese capital’s unique position as the first city 【小题10】（host) the Summer and Winter Olympics.

What is classic literature? Classics are the antiques of the literary world. They are novels, plays and poems that 【小题1】 (write) a long time ago and so well written were they 【小题2】 people still read them nowadays. They are examples of great writing and wisdom, and even those written centuries ago can still be found in bookshops and libraries today.

Because a lot of classics were written so long ago, their language characteristics are quite different from 【小题3】 of modern works. This makes them difficult for some people 【小题4】 (read), so they are often left to gather dust on shelves. Many people do not read them, because they think classics are old and boring and seem not 【小题5】 (close) related to life today.

However, if this is true, why do we still find these classics in bookshops and libraries? They have not disappeared and still have 【小题6】 place in the world. Why else would many films 【小题7】 (base) on them be successful? In 1995, an award-winning film adapted from Jane Austen's novel Emma 【小题8】 (come) out. Three years later, in 1998, a modern 【小题9】 (adapt) of Charles Dickens's novel Great Expectations appeared in cinemas. Nobody would bother to make these classic novels into films if they had nothing to do 【小题10】 contemporary life.
