一道SAT语法题 求解啊啊啊
The Dracula orchids, (aptly named because their) modified leaves resemble flying bats, have central petals that look like small white mushrooms.
(A)aptly named because their
(B)aptly named because of their
(C)aptly named because of having
(D)named that because they have
(E)named that because of their
我知道答案是D,但A为什么不对
看错了,答案是A, 但D有什么不对

1.the Dracula orchids 是复数,that 是单数.这已经让D错了.
2.括号中的若改为 named as such because their 语法本身倒是可以了,但与 A 相比,很显然不够简洁!更何况此改法备选项中压根儿就没有.
