B.    in the determination of how and when the islands of the West Indies were colonized by mammals

D.    for determining when the islands of the West Indies were colonized by mammals and how they were
E.    for determining how and when mammals colonized the islands of the West Indies

看了讨论,还是有些不懂
1.provide的用法到底是什么,我查到的就是provide sth for sb,但是有没有provide sth for doing的??
2.都说C中错是因为they的指代歧义,但是两句并列的句子,后一句的主语代词优先指代前一句的主语么????

我想知道C为什么错
GWD给的是E

还有就是C的when they did是不是一定要加so呀??为什么??- -

UP~

provide sth for sb没错
你把动名词理解为名词就讲的通了
provide  clues for determining
为决定提供线索

还有，你不觉得C有点啰嗦么when and how。。。。这个蛮常见的句型啊  分开来讲就啰嗦了

provide for固定搭配，C比E啰嗦。就酱紫。
这道题我第一次做的时候也选C了，看到to就想选了。

谢谢LS两位~~~
就是记住provide sth for...记住how and when....是比较简洁的用法~

E还是比C好点，总觉得C后面缺什么
另外也许从clue考虑，我觉得更想得通，clue for sth.

表示目的的一般都用to，但是provide和for有固定搭配就没有办法了

ruclcy

provide sth for doing, 没有provide to do sth .的用法，只有provide sth for sb的用法。C中did后面却宾语是硬伤。这题我也错了~

而且C里面有they。。。感觉指代是不是有歧义呢？
