Until the middle of the 19th century , China was completely closed to Europeans and to foreign travel. Thus it was impossible for early collectors from Europe and elsewhere to explore the country. There were several collectors during the early period.. It should be stated that during the hazardous journeys and at the risk of their lives , all these collectors ,amateurs, missionaries and travelers , who have collected extensively in western China, have enriched our gardens with fine collections of plants. 【设计意图】在学生阅读有关植物探索的背景知识之后，引用部分图片以及一个与奇妙植物
