Question

—The skirt looks different from the others and it’s really nice.
—Thanks. It _________ by my mother last month.

1. A.
   made
2. B.
   is made
3. C.
   has been made
4. D.
   was made

Answer 1

D
考查时态和语态。“这件裙子看起来和其他人的不一样，它很漂亮。”“谢谢。它是上个月由我妈妈做的。”it和make之间是被动关系，故用被动语态，又根据last month可知，用过去时。故选D。
