28. The farm as well as its neighboring hills we once spent so much time ____ on a new look as recently as last year.

A.on having taken

B.has taken

C.on has taken

D.having taken

答案

答案:C

考查语法结构, 但须前后兼顾。易错选B或C, we once spent so much time on实际作定语, on后所填是谓语动词, 由as well as连接的并列的句子主语, 谓语应和as well as之前的The farm保持一致,故用单数形式。
