Although a surge in retail sales have raised hopes that there is a recovery finally under way, many economists say that without a large amount of spending the recovery might not last.
Although a surge in retail sales have raised hopes that there is a recovery finally underway, many economists say that without a large amount of spending the recovery might not last. (A) have raised hopes that there is a recovery finally (B) raised hopes for there being a recovery finally (C) had raised hopes for a recovery finally being (D) has raised hopes that a recovery is finally (E) raised hopes for a recovery finally 划线部分主语是a surge,单数。In retail sales作a surge 的定语是企图另人以为主语是复数。立即排除A。其他选项的时态属于“百花齐放”型,要确认用哪一个,第一个工具:看有没有时间状语。没有。第二个工具:看另外一句的时态,因为两句的时态必须一致。Economists say, 一般现在时。立即得出答案为D。(有同学也许会说为什么用has raised,现在完成时,而不也用一般现在时呢?这个无法考证。但有一个前提必须得遵守,现在对现在,过去对过去。经常也有会前面一般现在时,后面现在完成时。)
