In the heat of battle, players have been observed to throw themselves across the court without considering the consequences that such a move might have on anyone in their way.

　　分析主干：players have been observed to...

　　不定式to throw...在句中作主語players 的補語;這是observe sb. do sth.結構的被動語態，作賓語補足語的省to 的不定式在被動語態中成了主語補足語，要把to 還原。動名詞considering...作介詞without 的賓語，介詞短語without considering...作throw 的狀語。

　　譯文：在比賽的白熱化階段，人們注意到球員從球場的這頭狂奔到球場那頭，根本就沒有考慮到他這樣的動作會對阻擋他的其他球員產生什么樣的后果。
