Although the language of ‘rights’ sometimes leads to confusion, by the late 1970s it was recognized in most societies that people have a right to health-care( though there has been considerable resistance in the United States to the idea that there is a formal right to health-care). (剑4, test4 passage 3)
● 分析：
本句的主句为“it was recognized in most societies that people have a right to health-care ”，其中it为形式主语，“that people have a right to health-care”为that引导的主语从句;“Although the language of ‘rights’ sometimes leads to confusion”为although引导的让步状语;括号部分为附加/补充的信息，为though引导的让步状语从句，在此从句中，“that there is a formal right to health-care”为that引导的同位语从句，做idea的同位语。
● 题目：
Looking back, it now seems quite incredible that in the national health systems that emerged in many countries in the years immediately after the 1939-45 World War, it was assumed without question that all the basic health needs of any community could be satisfied, at least in principle; the ‘invisible hand’ of economic progress would provide. (剑4, test4 passage 3)
● 分析：
本句为分号连接的两个分句，第一个分句较长，其主句为“it now seems quite incredible that…in principle”其中it为形式主语，that引导主语从句;“that emerged in many countries in the years immediately after the 1939-45 World War”为定语从句，作national health system的定语，关系词为that;在that引导的主语从句中，“that all the basic health needs of any community could be satisfied, at least in principle”为that引导的主语从句，it做形式主语。第二个分句为简单句。
