Paragraph 1 Lu Yu and his book Cha Jing
Paragraph 2 How tea spread to other countries
Paragraph 3 How tea was invented by accident
3a
Did you know that tea, the most popular drink in the world(after water), was invented by accident Many people believe that tea was first drunk about 5,000 years ago. It is said that a Chinese ruler called Shen Nong was the first to discover tea as a drink. One day Shen Nong was boiling drinking water over an open fire. Some leaves from a tea plant fell into the water and remained there for some time. It produced a nice smell so he tasted the brown water. It was quite delicious, and so, one of the world’s favorite drinks was invented.
An Accidental Invention
3a
A few thousand years later, Lu Yu, “the saint of tea”,
mentioned Shen Nong in his book Cha Jing. The book
describes how tea plants were grown and used to make tea. It
also discusses where the finest tea leaves were produced
and what kinds of water were used.
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. This 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.

We use passwords(密码)to keep our personal information secret and safe, but some passwords we use may not be as reliable as we think.
Splash Data, a computer security company, recently released a list of the 25 worst passwords of 2011.This list is based on the research of hackers’ files containing stolen passwords. According to the list, “password” is the worst and most common password. Many others on the list are numbers in order either forward (for example,1234) or backward. Letters on the keyboard in order, such as “qwerty” are also common, as well as some first names and animals. “Hackers can easily break into many accounts(账户) just by trying common passwords again and again, ” said Morgan Slain, CEO of Splash Data.
How can you make a strong password It should be eight characters or more, with a mix of letters, numbers and symbols. One way to create a long and easy-to-remember password is to separate short words with spaces or numbers. Having safe passwords is necessary for surfing the Internet safely. But it’s not the only thing you must do to keep safety online. Here are some other web safety tips:
Never give out information that will allow someone to find you offline. That includes your full name, address and phone number.
Don’t include your real name as part of your online screen name.
Never meet people you met on the Internet in person. If you insist on breaking this rule, meet in a very public place and consider taking an adult with you.
Top 10 worst passwords: 1.password 2. 123456 3. 12345678 4. qwerty 5. abc123 6. monkey 7. 1234567 8. letmein 9.trustno1 10. dragon
