人山人海：在诗词用语(poetic expression)里，老外也有使用："a (the) sea offaces"，颇有咱的"人山人海"的味道。

　　例如：Looking out upon the sea of faces, Mr. A delivered a touchingspeech.(望着一片人山人海的听众，A先生发表一篇动人的演说。)

　　Standing at his podium, President Clinton saw a sea of faces waving athim.(克林顿总统站在讲台上看到人山人海的人群挥手向他致意。)

　　可见，说话者通常要在台上或高处，才有"人海"的感觉。因此，可以说："I saw a sea of faces from the top of thebuilding. "但在平地的人群中，就不说："I saw the sea of faces."也不说："There is a sea offaces."只说："I saw a large crowd of people."
