首先来翻译一下这两个单词的意思，weariness ["wɪərɪnəs] n. 疲倦；困乏；消沉；厌倦 tiredness ["taɪədnəs] n. 疲劳，倦怠 。下面是它们的句子的对比weariness Despite his weariness, Brand mustered a wan smile... 虽然精疲力竭，布兰德还是无力地笑了笑。He showed absolutely no signs of weariness. 他毫无倦意。tiredness He had to cancel some engagements because of tiredness. 他太累了，不得不取消一些约会。看它表达的意思是不一样的，第一个单词（weariness)当一个名词来用，那第二个(tiredness)它形容词来用。我也许说的不太完善，希望对你有帮助！
