Wealth depends __________ (55) a great extent upon a country&39;s natural resources. Some regions of the world are well supplied with coal and minerals, and have fertile (肥沃的) soil and a favorable climate; other regions __________ (56) none of them. Next to natural resources comes the ability to __________ (57) them to use. China is perhaps as rich as the USA in natural resources, but suffered for many years __________ (58) civil and extemal wars.

For example, Britain&39;s wealth in food stuffs and other agricultural__________(63) would be much less if she had to depend only on those grown at home. Trade makes it possible for her surplus ( 过剩的) manufactured goods to be traded abroad for the agricultural products__________ (64) would otherwise be lacking. A country&39;s wealth is, therefore, much influenced by its manufacturing capacity,__________ (65) that other countries can be found ready to accept its manufactures. _________ 查看材料 A.calls
