________China has successfully launched its Shenzhou Ⅵ with two astronauts in it has shocked the world.

A.What   

B.As

C.It   

D.That

答案

考察主语从句的连接词。That引导起主语从句,在句中不担当任何成分,也不能省略,只是起引导作用。本题的主语从句That China has successfully launched its Shenzhou Ⅵ with two astronauts in it的句中结构很完整,使用用that引导即可。故D正确。
