(A) with large clawlike "thumbs" on its wings[T1], which[T2] probably helped them[T3] to
(B) with large clawlike "thumbs" on their wings[T4], which[T5] probably helped it to
(C) had large clawlike "thumbs" on its wings, which[T6] probably helped them
(D) had large clawlike "thumbs" on its wings, probably to help it
(E) had large clawlike "thumbs" on their[T7] wings, probably to help it
这道题答案选D，问一下 SVO， to do这种对吗？
因为之前有看过一份资料说SVO，to do是错误的。除了一种例外，那么就是SVO，（插入语例如：such as 啊之类的），to do是对的。

D是正确答案，所以这样肯定是对的。
这里后面的probably to help it climb up to....应该是独立主格，用来修饰前面一整句话。作者: HelloSusy 时间: 2016-6-11 20:43
