on the ground __ a pair of new shoes he bought.a.lying b.lie c.lies d.are laid

C

a.lying
现在分词作定语相当于定语从句
on the ground lying a pair of new shoes he bought.
=a pair of new shoes he bought is lying on the ground

肯定选C
a pair of 是单数 two|three...pairs of 才作复数处理
这句话是倒装句 句型就是：介词短语+谓语+主语
记住 有些还有一个选项是 does lie 这也是错的 应该直接加动词lie（注意单复数） 这里的he bought 修饰主语 a pair of new shoes，无关
再给你举个例子
A girl stood in front of the house. =In front of the house stood a girl.
In front of the house stands a girl.
In front of the house stand two girls.

B
地上摆着他买的一双新鞋。
首先这是个倒装句，可以改成。
A pair of new shoes he bought lie on the ground.
其次如果主语是a pair of + n，谓语动词一般用复数形式。
lie 躺着，不及物动词，此意义下一般不用被动语态。

c
倒装句
正确的语序为 A pair of new shoes he bought ______on the ground.现在再做,注意主语是pair,个数是“一”（以“双”为单位）,所以谓语动词用单三就可以了.句子中的he bought 是定语从句,修饰 shoes
类似的句子还有,
Around the lake _______(be) some trees.
In front of the classroom ______(be)a red bike.
答案分别是are 和 is 因为真正的主语在后面呢 前面的介词短语不可以做主语哦~·您做对了吗?
祝进步↖(^ω^)↗

C
语感。

说实话，这种多意词我很不喜欢，从语感上我选a
