Astronauts in a spaceship have to _______weightless conditions _______are quite different from ______are on the earth. 
A.do with; which; thoseB.deal with; that; that
C.solve; that; whatD.face; which; these

答案
C
解析
考查定语从句与宾语从句。句意“宇航员在太空船上需要解决和地球上很不一样的失重情况。”weightless conditions是先行词,后跟的定语从句缺少主语,用which或that;from后跟的是宾语从句,从句缺少主语,指在地球上的重力,用what代替。故选C。
