[求助]LZM7-12

雪落无声

The science of economics, which for     four decades was dominated by Keynesians, who at first stressed the government's role in stimulating the economy,but who were ultimately led away from solutions based on government intervention.


D,economics is one that for four decades has been


E,economics for four decades ,is one that was


答案，D，从时态可以选出来，但是如果把E，was改成 has been意思上有什么细微差别？economics for four decades has been one that


LZM解释：因为for时间短语修饰that 从句，表明“被K主义统治了40年之久”而不是修饰主句。在D中，他位于that 从句中做从句的时间状语，在E中位于主谓之间，做主句的时间状语。


同样的例子


Upset by the recent downturn in production numbers during the first half of the year,the possibility of adding worker incentives was raised by ther board of directors at its quarterly meeting.


D,the board of directors raised at its quarterly meeting the possibility of worker incentive being added


E,the board of directors ,at its quarterly meeting ,raised the possibility of adding worker incentives


key is E,E中去掉逗号，对意思有影响吗？


1.the board of directors raised at its quarterly meeting the possibility of adding worker incentives


2.the board of directors raised     the possibility of adding worker incentives at its quarterly meeting


3.at its quarterly meeting，the board of directors raised     the possibility of adding worker incentives


三句话除了强调的重点不同外，意思一样吗？

第一，LZM说得没错。


第二，E逗号不能去，3个选项中我觉得只有3跟原来相近(单独作句子时），其它不可取。

为什么逗号不能去？去了会改变意思？

1, 答案，D，从时态可以选出来，但是如果把E，was改成 has been意思上有什么细微差别？economics for four
decades has been one that --->> i don't think so. as here 'for 4
decades' modifies science, changed meaning.



2, E,the board of directors ,at its quarterly meeting ,raised the possibility of adding worker incentives

key is E,E中去掉逗号，对意思有影响吗？ --> the reason is the same to 1

3, 1.the board of directors raised at its quarterly meeting the possibility of adding worker incentives



2.the board of directors raised     the possibility of adding worker incentives at its quarterly meeting



3.at its quarterly meeting，the board of directors raised     the possibility of adding worker incentives



三句话除了强调的重点不同外，意思一样吗？ ---> yes to 1 and 2; 3 is no good
