英语介词后用 副词还是形容词 为什么wake up 后加tired 而不是tiredly

tired 过去分词修饰动词.
She woke up tired. 她在疲倦中醒来.
------------------------
和现在分词及短语一样,过去分词（past participles）或过去分词短语（past participial phrases）也可以充当副词,修饰谓语动词.
　　过去分词短语可以表达下列四种意思：
　　一方法或活动方式,如：
　　● He walked up and down, lost in thought.
　　● I sat before the desk until after mid-night, absorbed in writing.
　　● Surrounded by a host of fans, the film star left the airport excitedly.
　　二原因,如：
　　● Greatly disappointed, some staff decided to leave the place.
　　● Taken by surprise, the enemy surrendered.
　　三时间,如：
　　● Born and bred in a turbulent age, the older generation of people experienced all sorts of hardships.
　　● Thrown to the floor, the boy regained his footing a few minutes later.
　　四条件,如：
　　● Given more time, the slow learners would have done better.
　　● Criticised by someone else, Tony would not have flared up like that.
　　除了直接修饰动词之外,过去分词或短语也可以和连词合组成短语,表示下列四种意思：
　　⒈由 when, whenever, while, until 等连词引导,表示“ 时间”,如：
　　● When asked about his previous job, Bill said he had been a motor mechanic.
　　● Susan seldom speaks in class until spoken to.
　　⒉由 where, wherever 连词引导,表示“地点”,如：
　　● Mosquitoes should be completely exterminated where found.
　　● Retirees in good health should be invited to return to work wherever needed.
　　⒊由 if, unless 引导,表示“条件”,如：
　　● If kept for too long, some medicines will lose their effectiveness.
　　● We have made a point of not attacking unless attacked.
　　⒋由 though, although, even though 连词引导,表示“让步 ”,如：
　　● Though warned of the danger, they still went mountaineering.
　　● Even though defeated for a second time, our team did not give up hope for the ultimate victory.
　　此外,过去分词短语还可以和介词“with”或“without”连用,具副词作用.如：
　　● With the water pipe choked, there wasn't any more water for use.
　　● Without anything left in the kitchen, the Wangs decided to eat out.
　　最后,过去分词短语,在适当情况下,可以有自己的主语而变成独立结构（the absolute construction）,如：
　　● The old man listened, his head inclined to one side.
