有这样4道题目
New geneticevidence-together with recent studies of elephants' skeletons, tusks, and otheranatomical features-provide compelling support for classifying Africa'sforest elephants and its savanna elephants as separate species. D provides compelling support for classifying E provides compelling support to classify 解析： A provide B to do C - 表示A要做C

Most statesimpose limitations on the authority of the legislature to borrow money,with their objectives being to protect taxpayers and the credit of thestate government. A to borrow money, with their objectivesbeing to protect B to borrow money, the objectives ofwhich are the protecting of C to borrow money, limitations intended to protect D for borrowing money, of which theobjective is protecting E for borrowing money, limitations withthe intent of protecting 解析： 首先比较toborrow 和for borrow,根据原文意思，borrow动作发出者是legislature, 不定式做谓语动词比for doing更加说得通。所以在A，B， C三个选项中选择。 C选项出现同位语，优先考虑。请注意intend用法，此处一定要用被动语态，因为intend动作发出者是立法的人，而不是limitation 本身。eg. policy intended to increase sales. A选项with引导的独立主格加上being略显繁琐。 B选项更加不简洁。 选C

C politicians decided to postpone by atleast five years an ambitious plan for protecting wild salmon and otherendangered fish, and instead they proposed a series of smaller steps,intending. 选B
然后我现在开始混淆了！
第一题classify的主语是support，所以要用for；
那第二题borrow money的主语是the authority of the legislature，为什么不用for？
第三题rate the ...的主语是scale，为什么不用for？
第四题protect wild salmon是修饰ambitious plan的，为什么不用for？用to protect的话，难道不会产生歧义，变成postpone的目的吗？
好乱！求大神们解释！thanks！
