after eight years of fighting 如何解释？

有一读者问： 我发现《学英语》某期中的“正误辨析”的第二题似乎有点不妥，该题如下：

Wrong: After two days of my arrival I went to see him.

Right: Two days after my arrival I went to see him.

但在高二英语课本中却有：

After eight years of fighting, the Chinese people finally defeated the Japanese invaders.

如何解释呢？

上述“正误辨析”并无不妥之处。说“我到了两天之后”应该用 two days after my arrival。 after two days of my arrival 是讲不通的，因为 arrival 不可能持续两天。但可说 after eight years of fighting, 因为 eight years of fighting 的意思是“八年的抗战”， 亦即 fighting （抗战）持续了八年。
