不在于lose是瞬间还是延续,lost可以延续啊,Japan had lost 10 years since the their last recession.
我的理解是:关键在first这个词,人家强调的是2001年这一年,since1992;很有可能1992年也是lost的,之后一直没有lost,直到2001年又lost了;而lost多少,
指的是2001年lost多少,即“简单的事实”,所以用过去时

不同意LS说是2001年lost,我觉得这句话when引导的从句就是修饰1992年的,个人觉得判断时态还是主要从逻辑意思出发~和动词是否延续性关系不大~如:The film had started by the time we arrived at the theater. start也不是个延续性动词~
引用Manhattan上的一段话~
Note that we do not always use the Past Perfect for earlier actions. In general, you should use Past Perfect only to clarify or emphasize a sequence of past events.
The earlier even should somehow have a bearing on the extent of the latter event.

我同意你对resulting的看法~prep08笔记里提到过:
3) 现在分词在句尾用逗号隔开,必须要注意的一点是这个结构从来都没有失去过“做定语”的功能,只是优先做状语而已,即优先修饰到前面主句的主语和谓语。如下题如果前面主句的谓语是完成时态,那么既然已经完成了,drawing就无法再做其的伴随,所以只剩下做定语的功能 。
也就是说“,-ving"位于句末无法伴随完成时态~
例:OG12-21
Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are now drawing solid conclusions about how the human brain grows and how babies acquire language.
(A) Neuroscientists, having amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood, are
(B) Neuroscientists, having amassed a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are
(C) Neuroscientists amassing a wealth of knowledge about the brain and its development from birth to adulthood over the past twenty years, and are
(D) Neuroscientists have amassed a wealth of knowledge over the past twenty years about the brain and its development from birth to adulthood,
(E) Neuroscientists have amassed, over the past twenty years, a wealth of knowledge about the brain and its development from birth to adulthood,
答案是A。 OG对D项的解释: The final descriptor in present tense,now drawing conclusions....does not fit the opening clause, which is in present-prefect tense(have amassed a wealth)and seems to midify adulthood.
另外,我对resulting还有一些理解,因为从语法上来说,这里的resulting有两种可能,一个是修饰verb做伴随状语,一个是修饰前句做结果状语,即,语法上要么“表伴随”要么“表结果”,可是,result from本身的意思是“表原因”,所以……拧巴了~还有,我看正确的句子发现,resulting要放句末,一般就是用resulting in表结果~~不过这只是个统计结果~
关于时态这个……我也木有比Manhattan更好的解释了……这题我也就是觉得句意上木有必要去强调他两的先后顺序~但有点主观我觉得……其实做题时我是用resulting把B给排除的
~这种时态的逻辑意思我掌握的也不好~能不用我就不会先用……一起等大N看看有木有更好的理解!~~~
