课文呈现
It is believed that tea was brought to Korea and Japan during the 6th and 7th centuries. In England，tea didn’t appear until around 1660，but in less than 100 years，it had become the national drink. The tea trade from China to Western countries took place in the 19th century. ⑥This helped to spread the popularity of tea and the tea plant to more places around the world. Even though many
people now know about tea culture，the
Chinese are without doubt the ones who
best understand the nature of tea. ⑦
