问题 In devoting herself to the study of gorillas, Dian Fossey ______ on a course of action that was to cost her life.

选项 A、boarded
B、embarked
C、mounted
D、ascended

答案B

解析 动词词义与搭配题。由on a course of action可排除board“上车,上船,进入或登上(交通工具或船)”,mount“爬上,使上马”和ascend“攀登,上升”,故选embark on“着手,从事,开始一项冒险活动”。另注意:on board表示“在船上”;be mounted on表示“安装在……之上”。
