C E
句子结构：Surveys have shown that… elderly people… consume… or have…
主语是surveys，谓语是have shown，后跟that引导的宾语从句说明show的内容，宾语从句的主语是
elderly people，由who引导的定语从句修饰，并列谓语是consume和have。
考点：指代一致、逻辑表达、平行对称
指代一致，当句子中有多个复数名词时，注意 they 的指代对象，避免指代歧义的发生致使句子逻辑
关系混乱。
逻辑表达-修饰，副词修饰动词，形容词修饰名词，很多选项会将副词与形容词混用，使句子意思发
生变化，要特别留意；定语从句修饰紧临的名词或代词。
平行对称-句子，表达并列的含义，如果主语相同，最好用由 and 或 or 连接的并列谓语，平行且简洁。
(A) they的指代对象错误；or连接的并列结构不平行。
(B) they的指代对象不清楚；副词insufficiently修饰动词consume，与原句形容词insufficient修饰对象
不同，改变了原句要表达的意思。
(C) 被动语态的表达方式不清楚，没有说明施动对象；or having没有平行对象，因为前面是are
consumed。
(D) who引导的并列定语从句错误地修饰紧临的名词countries。
(E) 正确，宾语从句谓语结构是elderly people consume or have，who引导定语从句修饰主语。 |
