smile
1.说“对（某人）微笑”在smile后面接at，on或upon都可以。例如：He smiled at（或on，或upon）me. 似乎用at最普通，说“对（某人）表示特别爱好”在smile后面接on或upon，不接at。例如：He rejoiced when his sweetheart smiled (up)on him. 和Fortune always smiled (up)on him. 说“对于…一笑置之”在smile后面接at。例如：She smiled at her baby's efforts to catch the butterfly.
2.smile可以作“（经常的）笑容”解。例如：She had such a sweet smile that everybody loved her.
3.be all smiles是“笑容满面很高兴”，有时含有“表示不再生气”的意思。例如：She was all smiles when I met her in the evening.
4.smile是类名词，不是抽象名词。参见laugh(ter)
