There are mainly six types of tea in the traditional Chinese concept, namely, black tea, green tea, white tea, oolong tea, yellow tea and dark tea.Black tea is fully fermented, so its leaves and tea soup are red.The flavour and aroma of black tea are rich and robust with a little bitterness.Famous black tea includes Qimen black tea, Tanyang Gongfu, etc.Green tea is non-fermented and the tea soup is green.It has a more delicate and fresher flavour than black tea.Famous green tea includes West Lake Longjing Tea, Bi Luo Chun Tea, etc.White tea, originated in Fujian Province, is probably the rarest tea.It is slightly fermented, just left to dry as it is.White tea has a lighter colour than other types of tea with a subtle flavor.One of the most famous white teas is White Tip Silver Needle.Oolong tea is partially fermented and has the most difficult tea processing.The result is a distinctive flavour, which combines the freshness of green tea and the mellowness of black tea.Famous oolong tea includes Tie Guan Yin, Da Hong Pao, etc.Yellow tea is relatively unknown.It is fermented.In the tea processing, the leaves are mounded and dried by the heat of fermentation.The flavour is close to green and white teas.Famous yellow tea includes Junshan Yinzhen, Huoshan Huangya, etc.Dark tea is post-fermented, which gives the leaves a dark black colour.The tea soup has a strong aroma with a thick and robust flavour.Famous dark tea includes Hunan dark tea, Yunnan Pu-erh tea, etc.Choose the best answer A, B, C or D to complete each statement based on Passage B.11._____ tea is non-fermented.A.YellowB.GreenC.BlackD.White12._____ tea is slightly fermented and the rarest kind of all.A.GreenB.WhiteC.YellowD.Black13._____ tea is partially fermented and combines the freshness of green tea and the mellowness of black tea.A.WhiteB.BlackC.YellowD.Oolong14.The flavour of _____ tea is similar to green and white teas.A.whiteB.blackC.yellowD.oolong15.The soup of _____ tea has a strong aroma with a thick flavour.A.whiteB.blackC.yellowD.dark
考题
Is it the different types of tea plants that determine the colour and aroma of tea? The answer is no.Actually, it is the processing of tea that finally decides the tea types.For example, black tea requires 100% oxidation and green tea requires almost no oxidation.So tea processing is quite an important factor in the production of tea.Anyway, the normal processing of tea includes the following four basic steps:1.New leaves are spread in order to reduce water content until they are pliable enough to be rolled.This process is called withering.2.The second step is rolling the withered leaves.Oils and extra moisture are released.This process can be done with machinery or by hand.3.The third step is called oxidation or fermentation.In this process the leaves turn from green to bright copper in colour.This step decides what type of tea we want.4.The last step is drying the leaves to stop the oxidation process.The leaves should be dried thoroughly without burning.Decide each statement is T (true) or F (false) based on Passage B.6.The processing of tea decides the tea types.7.Green tea requires a little oxidation.8.Withering makes the tea leaves release oils and water.9.Rolling the withered leaves can be done only with machinery.10.Burning the leaves is the last step of tea processing.
