请教曹老师：

In 1963 a Lancaster bomber crashed on Wallis Island, a remote place in the South Pacific, a long way west of Samoa. The plane wasn't too badly damaged, but over the years, the crash was forgotten and the wreck remained undisturbed. Then in 1989, twenty-six years after the crash, the plane was accidentally rediscovered in an aerial survey of the island. By this time, a Lancaster bomber in reasonable condition was rare and worth rescuing. The French authorities had the plane packaged and moved in parts back to France. Now a group of enthusiasts are going to have the plane restored. It has four Rolls-Royce Merlin engines, but the group will need to have only three of them rebuilt. Imagine their surprise and delight when they broke open the packing cases and found that the fourth engine was sweet as honey -- still in perfect condition. A colony of bees had turned the engine into a hive and it was totally preserved in beeswax!

曹老师，

1) a long way west of Samoa: a long way是名词词组作副词状语修饰“名词west+of Samoa“吗？

2) 上句中的by this time 有的书上说：在此之前，有的书上说：到了这个时候。究竟是什么意思呢？和 by the time 一样吗？另外，感觉应该是 a Lancaster bomber in reasonable condition "had been" rare ?是由于状态动词可以不使用过去完成时吗？

3) 第二个问题一直想问您的，在英语语法网上，我发现对于 be + V-ed, 您有时按照被动语态-强调动作来分析，有时又按照系表结构-强调状态来分析。这是不是要根据语境来判断？

我特别想知道的是：是不是几乎所有的be+V-ed: 在特定的语境中，既可以理解成被动语态-强调动作，又可以理解成系表结构-强调状态？

（以前一直有一个误区，就是认为这种be+V-ed只能是被动语态强调动作，除非词典将这种V-ed已经单独列为形容词，其实不是的，不管词典是否单独将V-ed列为形容词或没有，都可以在特定的语境中，将几乎任何的be+V-ed这种形式看作

形容词-系表结构-强调状态，也就是叫作“伪被动语态” -假的被动语态-实则是形容词系表结构？- 这种理解对吗？）

譬如这里的wasn't too badly damaged - 就应该理解为系表结构-而不是被动语态！但是 the crash was forgotten 和 was accidentally rediscovered - 应该理解成被动语态还是系表结构呢？为什么？
