标题: 求助OG两道，OG12-86和OG12-87 [打印本页] 作者: luopite 时间: 2010-9-20 21:01 标题: 求助OG两道，OG12-86和OG12-87 86.The result of the company's cost-cutting measures are evident in its profits, which increased 5 percent during the first 3 months of this year after it fell over the last two years. C.which have increased 5 percent during the first 3 months of this year after falling. E.with a 5 percent increase during the first 3 months of this year after having fallen. 正解C，我选的是E。 OG: This sentence describes two sequentially ordered indicators by which the results of a company's cost-cutting measures can be seen. The first indicator to be identified, a 5 percent increase in profits, occured after the indicator mentioned next. The sentence therefore needs to clarify the sequence by presenting the first-indentified indicator in a clause with a verb tense that indicates a later time period than the verb tense in the clause presenting the second-indentified indicator 这话说的是什么意思……是指的时间状语的前后关系应该和动词的时态一致么？ 解释说E是错的，it is not clear what connection is being described by with.为什么用with不对呢？
87. In an effort to reduce their inventories, Italian vintners have cut prices; their wines have been priced to sell, and they are. B.are priced to sell. and they have C are priced to sell, and they do D.are being priced to sell, and have E.had been priced to sell, and they have 这句话什么意思？如果说they后面补出助动词的话应该和前面的哪个动词对应呢？ 另外还想请问，分号的作用是用来解释的吗？是不是分号分开的句子都应该是有主谓的完整句子呢？

2.时态问题。
3.AlienX: after having done something是不可能对的
1)after已表示the sequence of events.没有必要用having done来表示前后
2)可是after someone/something has/have done something是acceptable; 如果变成after someone/something did something也可以
1.对主谓宾全的句型主语比较：A do sth than B do.（AB为对等名词，加do是为了显示这是一个可以发出动作的名词，因而确定是主语，进而确定是主语对比）。时态要据后定。There be 句型等同于一般的主谓宾俱全的句型。
主语若相同，可省，但助动词不能省。如：
As a result of the continuing decline in the birth rate,[fewer people]will enter the labor force [in the 1980’s] than (few people 省略)did [in the 1960’s and 1970’s], a twenty-year period during which people born after the war swelled the ranks of workers.
I eat faster than you.注意与下句区别 I eat apple faster than you do 如果写成 I eat apple faster than you 按GMAC的理解，从语法上就变成我吃苹果比吃你快，成了宾语比较。逻辑上显然不通。
3.主系表结构的比较与主谓结构相同。如果时态不一致，则需补出助词，如：
The economy of Florida is more diversified than it was ten years ago比较-主语比较

I eat faster than you.注意与下句区别 I eat apple faster than you do 如果写成 I eat apple faster than you 按GMAC的理解，从语法上就变成我吃苹果比吃你快，成了宾语比较。逻辑上显然不通。

请问C选项的after falling补全了是什么？they are falling?为什么会是现在进行时？已经停止跌了，开始涨了啊~~而且last two year 不应该是过去时were 吗？不是说时态不一致不能省略吗作者: luopite 时间: 2010-9-27 10:37

个人理解，falling是现在分词用来修饰which指代的prifits, 因为over the last two years, profits fall的动作是持续重复的，所以表示持续重复的动作是可以用现在分词来做修饰成分的。
