问题 Without the friction between our feet and the ground, we may not be able to walk.
选项 A、wouldn’t be
B、were
C、were not
D、can’t be
答案 A
解析 这句话的意思是：如果没有脚和地之间的摩擦，我们就不能行走。本句属于隐含式虚拟语气。句中without短语相当于一个与现在事实相反的虚拟条件句。在without引导的虚拟语气中，表示与现在事实相反时，谓语动词为would／could／might(not)do something；表示与过去事实相反时，谓语动词结构为would／could／might(not)have done something；表示与将来事实相反时，谓语动词为would／could／might(not)do something。此处与现在事实相反。答案为A。
