The Space Age _________ in October 1957 when the first artificial satellite was launched by the So- viet Union.
选项
A、initiated
B、originated
C、embarked
D、commenced
答案
D
解析
动词辨异。initiate是及物动词,意为“开始,发起,创始,倡议”;originate作不及物动词时,意为“发源,来自,产生”;embark意为“上(飞机、汽车等),发动,着手”;commence是不及物动词,意为“开始,使开始,着手”。根据句子结构和句意应选D。句意为:太空时代始于1957年10月,那时候第一颗人造卫星由苏联发射升空。
