Q1: elaborate为什么会和extensive近义
Q3: 文章中说The first few years after the initial settlement at Massachusetts Bay in 1630 seemed to fulfill those expectations.....Yet Within a dacade the colonists' ecnomy suffered a sharp, severe decline. 我觉得这并不能作为New England的economy在1640年前剧烈衰退的原因阿,起码最开始的a few years并不是这样的。
Q35: eventually 和 in time近义?~~~迷茫中~~~
Q42: extend为什么不能选A broaden?
