例1：According to a 1996 study published in the Journal of Human Resources, Americans of Middle Eastern descent were twice as likely as was the national average to be self-employed.
(A) as was the national average to be self-employed
(B) as the average American to be self-employed
(C) as the national average that they would be self-employed
(D) to be self-employed than was the average American
(E) that they would be self-employed than was the national average
句子结构：According to…, Americans of… were twice as likely as… to be… 比较结构。
考点：比较、习惯用语
比较，A as… as… or adj.er than B; A at least as adj.er as B，常见的错误用法有：A as… or adj.er than B(少 as); as…as compared to; as… than compared to; as… than 搭配。习惯用语-likely，be likely to do 或 it +be likely that 从句。
解析：
(A) the national average表达不清楚;was可以省略。
(B) 正确，the average American与Americans of …对称，be likely to do。
(C) the national average表达不清楚;be likely that…的正确表达方式是用it作形式主语it+be likely that…，而不是sth be likely that…;they指代对象不清楚。
(D) as… than搭配错误。
(E) as… than搭配错误;be likely that…的正确表达方式是用it作形式主语it+be likely that…，而不是sth be likely that…;was可以省略。
例2：
Shrinking faster than any other nation's, the projected decline of Japan's population is 17 percent during the next half century.
(A) Shrinking faster than any other nation's, the projected decline of Japan's population is
(B) Shrinking faster than any other nation, Japan's population has a projected decline of

(D) The Japanese population is shrinking faster than any other nation, and it has a projected decline at
(E) Japan's population is shrinking faster than that of any other nation, with a projected decline at
句子结构：The population of … is shrinking faster than that of… and is projected to…
主语是population，并列谓语为is shrinking and is projected to。
考点：比较、简洁有效
1) 比较，不同范围的相同比较对象对比时，第二个要用代词指代，缺少代词会导致比较对象不对等。
2) 简洁有效，动词比形容词和名词更能清晰有效地表达原句意思。
解析：
(A) 现在分词结构在句首修饰主句主语decline，不符合逻辑。
(B) population和any other nation比较对象不对等。
(C) 正确，that指代population，两国的population对比，is shrinking… and is projected…并列谓语。
(D) population和any other nation比较对象不对等;has a projected decline表达罗嗦，动词project比形容词projected更有效。
(E) 名词a decline at…不如动词decline by…表达的含义清晰。
