A. of which the top; with it’s top         B. whose top; with its top        

C. whose top; the top of it              D. the top of which; with it’s top

Answer 1

B

 解析:

试题分析：考查定语从句和with复合结构，第一空是定语从句，先行词是a larger plastic bottle定语从句定语从句的top需要定语，用whose top= of which the top=the top of which，所以第一个空都可以，第二空是with its top as a pot to grow flowers in 做伴随状语，补充主句。句意：你可以用一个大的塑料瓶，切掉瓶子的顶部，把它的顶部当做一个养花盆。

考点：考查定语从句和with复合结构

点评：，“whose +名词”结构常可以用“名词+of which” “of which+名词”结构来替换，且意思相同。还要注意it's 表示它是，its 才是它的。
