Question

the spaceship___space at nine A was blasted off B blasted off C was launched
launch和 blast off 有什么区别?blast off有被动形式吗 （be blasted off）

Answer 1

答案：B


launch作为“发射”讲时,是及物动词,其后加the spaceship这样的名词短语做宾语.
如：launch the spaceship into space
如果用the sapceship这类名词做主语,用launch做谓语的话,则必须使用被动语态,即：
the spaceship was launched into space
答案C虽然使用被动,但是缺少into这种介词的连接,排除；
blast off用法复杂,主要有这三种用法：
1）blast off做不及物动词,且off视为副词,the spaceship此类名词做其主语,不用被动语态
the spaceship blasted off into space...
2）blast off做及物动词,且off视为介词,the spaceship此类名词做其主语,“离开的地方”做其宾语,即：the spaceship blasted off space
3）blast off做及物动词,且off视为副词,the spaceship此类名词做其宾语,可用于被动语态,即：
China blasted the spaceship off into space...
楼主的题目如果没有打错的话,则此题使用blast off的第二种用法,off视为介词,直接加space做其宾语.
