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

試題分析：考查定語從句和with復(fù)合結(jié)構(gòu)，第一空是定語從句，先行詞是a larger plastic bottle定語從句定語從句的top需要定語，用whose top=" of" which the top="the" top of which，所以第一個空都可以，第二空是with its top as a pot to grow flowers in 做伴隨狀語，補(bǔ)充主句。句意：你可以用一個大的塑料瓶，切掉瓶子的頂部，把它的頂部當(dāng)做一個養(yǎng)花盆。
點(diǎn)評：，“whose +名詞”結(jié)構(gòu)�？梢杂谩懊�詞+of which” “of which+名詞”結(jié)構(gòu)來替換，且意思相同。還要注意it's 表示它是，its 才是它的。
