Mountains cover about a quarter of the world’s land surface. They are critical【C1】________of the Earth’s surface and provide vital resources and 【C2】________ecosystems to a significant proportion of the global population. As the water towers of the world,【C3】________regions are important water suppliers for nearly half of all people. In addition to water, mountains also【C4】________timber and non-timber forest products, mineral resources, and many other food, fiber, and fuel products. Moreover, mountain ecosystems provide carbon storage, nutrient retention, a provision of clean oxygen, a destination for tourism and recreation and pest control. Therefore, mountainous regions【C5】________ecosystem security, and are key natural resource bases for human development due to their ecological, social, and economic values.

Whilst there are three different【C7】________to mapping mountainous areas of the world, each with its own history and applications, it is clear that mountains 【C8】________a significant proportion of global land area.

答案
O
解析
动词辨析题。分析句子结构可知,空格前是名词mountains,空格后是名词timber,且空格所在句缺少谓语,因此,空格处应填入一个动词作句子的谓语。空格前一句提到山川的一个作用,即提供了重要资源和至关重要的生态系统。结合空格所在句前半部分提到的“除了提供水资源之外”可知,空格处也应表示山脉对地球的重要作用,故yield“出产,产生”为答案。
