After circling around the earth for three days,Shenzhou Spaceship received thecommand from the ground that( )as scheduled the next day.A,it has landed.B,it lands C,it will land D,it land为什么不是C,
command 命令,无论是动词,还是名词,后面出现句子都要用虚拟语气,也就是should +do; should 可以省略的.
为什么不是C
你看看前面的主句用的是一般过去时态,后面的时态怎么可能用一般将来时呢.即使用,也要用过去将来时态.
这个应该是省略了should ,完整的是it should land,因为先行词是command
将来时与一般现在时
command 的用法 A command that B do sth. A command B to do sth.
