【正确答案】China is a large country and each area has its own specialties. So there have been different opinions on classifying them into different schools. In my opinion they could be roughly classified into four major schools, namely, the Northern School, the Sichuan School, the Jiangzhe School and the Southern School.
The Northern School is usually called the Beijing School. Dishes of Beijing School actually come chiefly from the Shandong School ( of Shandong Province). Most of the dishes have a high calorie value answering the demands of the cold northern climate.
The uniquely hot, pungent flavor of Sichuan cuisine is created by a mixture of spices and condiments, including hot pepper, garlic and ginger. Besides, Sichuan Province has always produced skilful chefs. The ingredients of Sichuan dishes consist chiefly of mountain products and river fish, because Sichuan is an inland province.
The Jiangzhe School, which is also called Shanghai School, is actually a collective term for all the cooking styles of the middle and lower reaches of the Yangtze. As it is a coastal area and with a great number of rivers and lakes, this school has really an infinite variety of dishes.

【答案解析】[听力原文]
中国幅员辽阔，各地都有自己的特色菜，所以有几个菜系说法不一。我看大体上可以分成四个菜系，即北方菜、四川菜、江浙菜和南方菜。
北方菜俗称“京菜”。实际上京菜的大部分菜式来自鲁菜，即山东菜。因为中国的北方气候寒冷，所以很多菜式选用含卡洛里较高的用料，以保证足够的热量。
川菜选用辣椒、蒜和姜等做调料，构成了川菜独特的麻辣浓味。此外，四川历来出名厨。川莱的用料主要来自山区和河流，因为四川是个内陆省。
江浙菜系亦称上海菜系。此菜系实际上集合了长江中下游地区的各种菜式。这一地区靠海，周围又有许多江湖，因此，这个菜系品种极为丰富。
