We should keep it in mind that beneath our feet that our life depends on for food and clothing.

A. lies the earth

B. lying the earth

C. does the earth lie

D. the earth is lying

答案：

(答案→)A. lies the earth

B. lying the earth

C. does the earth lie

D. the earth is lying

解析：考查倒装句。本题是把表地点的介词短语beneath our feet放在句首，后面的句子主语是名词the earth，构成完全倒装句。Lie是真正的谓语动词，因为主语是earth，所以使用单数形式。故A正确。
