You can use a large plastic bottle, cut off, as a pot to grow flowers in.
A. the top is
B. with its top
C. whose top
D. the top of which

A. the top is(答案→)B. with its topC. whose topD. the top of which解析：考查非谓语。句意：你可以用一个塑料瓶，把塑料瓶的顶部切下来，做一个花瓶来种花。排除C和D 是因为空后是一个非谓语done，不是句子不能用连词，A不对是因为选了A构成了两个简单句没有连词，B构成with的复合结构：with + 名词或代词 + done，名词活代词和done之间构成被动关系，所以B正确。
