1500年以前，丝绸的生产是中国的国家机密
Fifteen hundred years ago in China, silk production was a state secret.
The silk trade was so valuable that anyone who tried to take silkworm eggs or mulberry seeds out of China was put to death. Then in 552 AD, two monks 1 smuggled 2 silkworm eggs to Constantinople, and silk production spread worldwide. Now that the secret's out, we can safely talk about how silkworms and humans make luxurious 3 silk cloth.
A silkworm actually isn't a worm at all. It's a type of caterpillar 4 that once existed in the wild, but now only survives in domesticated 5 form. Silkworms are fussy 6 eaters, dining only on mulberry leaves. When a silkworm has had its fill, it spins a cocoon 7 from a single strand 8 of silk, two to three thousand feet long!
According to legend, a Chinese empress discovered how to harvest silk when a cocoon fell into her tea. She plucked it from the teacup by the loose end of the silk, then unraveled the whole cocoon. To harvest silk commercially, cocoons 9 are first steamed to kill the pupae inside. That's because the silkworm would break the silk if it began to emerge as a moth 10. Next the cocoon is dunked in hot water--rather than tea--to dissolve the sticky coating that binds 11 the silk. Then a machine unwinds the single strand that makes up each cocoon. Twisted together, these strands 12 make the fine thread used to weave silk cloth.
Next time we'll talk about how humans have bred silkworms to behave quite unlike their caterpillar cousins in the wild.
