Q1:

Scientists claim that the discovery of the first authenticated mammal bones in amber could provide important clues of determining, in addition to how, when mammals colonized the islands of the West Indies.

 

1. of determining, in addition to how, when mammals colonized the islands of the West Indies
2. in the determination of how and when the islands of the West Indies were colonized by mammals
3. to determine how mammals colonized the islands of the West Indies and when they did
4. for determining when the islands of the West Indies were colonized by mammals and how they were
5. for determining how and when mammals colonized the islands of the West Indies

给出的答案是e,不太明白how and when这样并列可以吗,我选了c

C的一个明显错误是 when they did后面少一个“SO”

从整个句子来看mammal bones提供了线索，后面应该是mammals（如何和何时）统治....

所以选择E.

C中to应该接sth.

例：give a clue to sth. or provide a clue to sth.

thank you very much!

问一下二楼为什么c一定要在did后面加so..不太明白

三楼:give a clue to sth ,or provide sh to sh 是固定搭配吗,provide还有什么用法,帮忙罗列一下,多谢!
