1.        Madagascar was one of the last habitable areas of the earth to undergo human settlement, which has made it an ideal site for researching rare flora and fauna.

(A) Madagascar was one of the last habitable areas of the earth to undergo human settlement, which has made it

(B) Madagascar was one of the last habitable areas of the earth to have undergone human settlement, and that has made it

(C) Madagascar underwent human settlement as one of the last habitable areas of the earth, which makes it

(D) Madagascar, one of the last habitable areas of the earth, underwent human settlement, making it（E）

(E) Because Madagascar was one of the last habitable areas of the earth to undergo human settlement, it is

B错在那里？

1.因果关系比并列关系好

2.which 不能指代句子，B里变成指代settlement了。（在强调一下，which不能指代句子！！！改为概括性名词获分词结构表伴随结果或伴随动作）

3.that has made it错，that/this/these.those均不能单独作主语，后面要跟名词。这也就是所谓的“This is an apple”是错误的。（这可是我这辈子学的第一句英语完整句啊，小学的美好记忆就被ETS粉刷了……）

还有个疑问，B中的时态has made it 是否正确呢？
