The general nature of his history meant he could not analyze carefully what this obsecure officer may or may not have contributed to that struggle between nations.
请问专家 what 引导的疑问从句中,为什么会用一般完成,而不用过去完成呢?
The general nature of his history meant he could not analyze carefully what this obsecure officer may or may not have contributed to that struggle between nations.
1. obsecure officer
拼写错误,应为 obscure officer(无名军官;鲜为人知的军官)。If something or someone is obscure,
they are unknown, or are known by only a few people. 鲜为人知的
2. 英语中没有“”一般完成”这个术语,请使用正确的表述。
3. 情态动词 may 的用法之一是表推测,may have done 表示对过去的推测。与主句的 could not analyze 在时间上是一致的,都表示过去。情态动词后的 have done 称为不定式完成体,may had done 是不存在的。
