一是意思意义范围不同 二是前者take place 常指意料之中或是特地安排的的事（如召开会议等等）, 后者不可以这样用. 见下例： take place 发生; 举行 The threatening strike did not take place after all. 可能来临的罢工终究没有发生. The evening party will take place on New Year's Eve. 晚会将在除夕那天举行. come about 发生 The flood came about as a result of the heavy spring rains. 春季的大雨造成了洪水泛滥. 改变方向 The ship came about and headed for safety. 船改变了航向向安全地带驶去. 请及时采纳,不懂继续问( 天天在线 ） (*^__^*) 祝学习进步! 谢谢!
