圣人，圣徒LuYuiscalled“thesaintoftea”.神农说唐．陆羽《茶经》：“茶之为饮，发乎神农氏。”，在中国的文化发展史上，往往是把一切与农业、与植物相关的事物起源最终都归结于神农氏。而中国饮茶起源于神农的说法也因民间传说而衍生出不同的观点。有人认为茶是神农在野外以釜锅煮水时，刚好有几片叶子飘进锅中，煮好的水，其色微黄，喝入口中甘甜止渴、提神醒脑，以神农过去尝百草的经验，判断它是一种药而发现的，这是有关中国饮茶起源最普遍的说法。另有说法则是从语音上加以附会，说神农有个水晶肚子，由外观可得见食物在胃肠中蠕动的情形，当他尝茶时，发现茶在肚内到处流动，茶来茶去，把肠胃洗涤得干干净净，因此神农称这种植物为“查”，再转成“茶”字，而成为茶的起源。陆羽，出生于湖北天门，生活在唐朝时期，他撰写的《茶经》，对有关茶树的产地、形态、生长环境以及采茶、制茶、饮茶的工具和方法等进行了全面的总结，是世界上第一部茶叶专著。《茶经》成书后，对中国茶文化的发展影响极大，陆羽被后世尊称为“茶神”、“茶圣”、“茶博士”。1.Oneoftheworld’sfavoritedrinkswas_________byaccident.2.Teawasfirst________byShenNong5,000yearsago.Completethesentenceswiththecorrectformsoftheverbsinthebox.invent,drink,bring,produce,tradeinventeddrunk3c3.Anicesmellwas_________whenthe tealeavesdroppedintothehotwater.4.Teawas________toKoreaand Japanduringthe6thand7thcenturies.5.Teaisnow______betweenmany differentcountries.tradedproducedbroughtinvent,drink,bring,produce,tradeItissaidthataChineserulercalledShenNongwasthefirsttodiscoverteaasadrink.Itissaidthat…是英语的一个固定句型，表示“据说，相传，据传说”类似表述还有Theysay…,Peoplesay…等Thelanguagepoints.ItisbelievedthatteawasbroughttoKoreaandJapanduringthe6thand7thcenturies.Itisbelievedthat…表示“人们相信，人们公认，大家认为”等意思类似句型有：
