10、据句中 among the lowest in Britain 和 probably one of the highest 可知前后的意义存在对比；while 用作连词, 可用于表示对比或相反的情况, “而；但是”。名词性从句区别什么从句应看主句，主句不完整时从句肯定是名词性从句。主句完整时，从句可能是定语从句，状语从句，或者同位语从句。需要用什么引导词看从句。名词性从句中缺什么意思用什么意思的引导词; 缺名词性成份时，指人用 who/whom，指物用 what; 不缺意思和成份时用 that。That 只有在宾语从句中可以省略。缺成分时,what 和 whatever 是第一高频答案!引导主
