After centuries in the desert，the locals have developed a unique musical practice when they want a mother camel to accept a newborn baby camel.When the practice starts，a musician plays his instrument，usually a Mongolian flute.The mother and baby are tied together，and another musician begins to sing: “khuus，khuus，khuus.” At first，the mother either pays no attention to the baby or treats it badly.The “coaxer(劝诱者)”，at this point，changes the music based on the behavior.The singer begins to copy the sound of the camel's walking，running and voices.After many hours of this，the mother and baby are in tears，and are joined for life. However，each year fewer and fewer young people are willing to learn and pass on this tradition.In addition，more and more Mongolian families are sending daughters away to study and live in cities，and those who leave almost never return.The young men who remain in the desert struggle then to find wives and raise families that can help raise camels and keep the traditions alive.On top of that，many have discovered that motorbikes are cheaper than camels.All of this are killing the traditional way of life. A few Mongolians have turned to the United Nations to help save this practice.In 2015，they added it to their “List of Intangible Cultural Heritage in Need of Urgent Safeguarding”，but it's hard to know what influence this can have beyond recognizing the existence of the practice. 语篇解读　这是一篇说明文，主要介绍了蒙古族的一种习俗——通过音乐来加强母骆驼和小骆驼的关系。然而随着当地人生活方式的改变，这种习俗已经处于濒危状态。 1．Why did the locals develop the Mongolian practice?

China first started exporting tea during the Ming Dynasty (1368－1644)，and the drink has since come to lead humanity's drinking habits far beyond Asia.It is the most widely consumed drink on Earth today，aside from water and coffee. In Chinese mythology，tea was first discovered by Chinese Emperor Shennong (“Divine Farmer”) in 737 BC，when a soft wind carried some leaves into a pot of boiling water.However，the oldest dependable evidence comes from ancient plant remains found in 2016 in Xi'an and western Xizang，showing that tea was grown at least 2，100 years ago during the Western Han Dynasty when it was most likely used as medicine. Generation after generation of tea makers experimented with different brewing(冲泡) techniques，leaves，and ceremonies，resulting in today's tea culture full of life.There's no doubt that China's tea culture has become one of the most popular，diverse，and unique traditions in the world. China is already the world's largest tea exporter.The inclusion of the country's traditional tea-making process on the UNESCO list will obviously generate practical benefits for tea makers in the country and across the world as more resources are given to protect and preserve such millennia-old tea culture and technical practices.As additional attention is brought to this traditional technique，the Chinese tea sector will further tap its potential and improve its growth. As one of China's oldest cultural practices，traditional tea processing techniques show the spirit of modesty，peace，and comity(礼让).No matter what your preference for green or dark tea is，with milk or without，Chinese tea isn't just a brew.Instead，it is a bridge connecting different cultures and peoples. 语篇解读　本文是一篇说明文。中国传统制茶工艺是最古老的文化习俗之一，体现了谦逊、和谐和礼让的精神。中国茶是一座连接不同文化和民族的桥梁。 5．What does the first paragraph mainly tell us? A．Chinese tea has a fresh taste. B．Chinese tea has a rich variety. C．Chinese tea has a long history. D．Chinese tea is added with spices. 段落大意题。根据第一段的“Today，the country owns over 2，000 varieties of tea，differing in taste，sweet and purpose.”及下一句的举例说明可知，本段主要阐述了中国的茶品种丰富。故选B。 √ 6．How does the author find about Chinese tea?
