常見錯誤
What are common mistakes with "Coarsen"?Which "Coarsen" sentences look correct but are wrong?
×The weather coarsened the wood.
✓The weather made the wood coarse. / Exposure to the elements coarsened the wood's texture.
"Coarsen" 通常指質地、態度或品質變得粗糙或粗俗，主語通常是導致變化的因素（如風、水）或事物本身。此處錯誤在於將天氣作為主語直接作用於物體，語意不清。應使用更清晰的表達，或說明天氣如何使木材質地變粗糙。
×His voice coarsened because he shouted.
✓His voice became coarse from shouting. / Shouting coarsened his voice.
"Coarsen" 作為及物動詞時，主語是導致變化的原因；作為不及物動詞時，主語是發生變化的事物本身。原句語法正確，但 "because he shouted" 略顯口語化且因果關係直接。使用 "from + V-ing" 或將 "shouting" 作為主語更為地道，強調過程導致結果。
×Don't coarsen your manner.
✓Don't let your manners coarsen. / Don't become coarse in your manners.
"Coarsen" 用於描述態度、舉止變粗魯時，通常作不及物動詞，主語是 "manners"（常用複數）、"tone"、"language" 等。原句錯誤地將其作為及物動詞，並使用了單數 "manner"。應修正為主語變化或使用 "become coarse" 的結構。
×The teacher coarsened the student's essay.
✓The teacher said the student's writing had coarsened. / The student's writing coarsened over time.
"Coarsen" 描述品質、質地或風格的負面變化，通常不適用於他人直接施加的動作（如老師批改）。它暗示一個漸進或受影響的過程。原句易誤解為老師故意使文章變差。應調整為描述學生寫作自身變粗糙，或使用其他動詞如 "made...worse"。
×I coarsened the sugar into powder.
✓I ground the sugar into coarse granules. / I made the sugar coarser.
"Coarsen" 意為「使變粗糙」，而非「將某物加工成粗糙顆粒」的具體動作。它描述狀態變化，不指特定的物理加工行為（如研磨、切割）。原句混淆了動詞與過程。應使用 "grind"、"make coarse" 或 "become coarse" 等更準確的表述。
