1.At the foot of the mountain ___B_____.
这是个地点状语开首的完全倒装句,你可把它还原为:“ A village lies at the foot of the mountain.”,这样应该就看得很清楚了.你选D错误的原因在于lying是非谓语动词,整个句子就没有谓语了.
A.a village B.lies a village
C.does a village lie D.lying a village
2.You may drop in or just give me a call.你可以来访或者给我打个电话.Either will do.两种办法都可以.
注释：本题只能填 either(两者任择其一；两者中的任何一个) ,不能用each（每个）,因为句子的意思是两种办法随便选一种,只能用either.而each表示每一个都要,与题意不符.
