The laughter overtook me.=I was overtaken with [by] laughter.
つい笑ってしまった
The laughter was absent for a while.
笑いがしばらくとぎれた
the mysterious smile of the Mona Lisa
モナ・リザのなぞめいた微笑
The play is balanced between comedy and pathos.
その劇は笑いと哀感とのつり合いが上手くとれている
the pot calling the kettle black
((諺))(自分のことを棚にあげて)なべがかまを黒いという,目くそ鼻くそを笑う
The smile died on her face.
彼女の顔から笑みが消えた
The smile froze on his face.
彼の笑っていた顔が急にこわばった
The smile slipped away from his face.
彼から笑顔が消えた
The smile vanished from her face.
彼女の顔から笑顔が消えた
The smile was very near to a smirk.
その微笑みはほくそえみといってよかった
