第99页，14和15题

14. Last night our air conditioner broke, whichcaused great consternation

解释：which caused great consternation: incorrect. This modifier is dangling, sincethere is no noun correctly modified by the clause which caused greatconsternation. The author’s intent is to comment on the event. But the mainclause does not name the even with a noun. Therefore, we need to change themodifier to a verb modifier, either a participle (causing..) or an absolutephrase( an event that caused:

correction: last night our air conditioner broke,causing great consternation.

15. the patient’s rare disease was treated using noveltechniques developed at the medical school

解释：usingnovel techiniques: Incorrect. This modifier is dangling, since the sentencecontains no noun that is properly modified by using novel techniques. To fixthe sentence, we can introduce an agent who actually used the novel techniques(e.g. a doctor), or we can switch to a prepositional phrase, such as throughthe use of novel techniques, that does not contain an –ing verb form.

Correction: the patient’s rare disease was treatedthrough the use of novel technique developed at the medical school

问题来了，这两句问题点类似，都是modifier is dangling, because there is no noun correctly modfied.。。。 第一题的解释说那可以用causing（现在分词）来作为verb modifier(我的理解就是修饰broke)

但是第二题， 人家已经是在用using了啊，那就已经是在用using 作为verb modifier来修饰treated了对不对！ 结果解释里又说contains no noun that is properly modified.. 这明明是verb modifier了呀？？

求大牛指导，完全糊涂了。 而且modifier这章也没有定义到底有哪些可以作为verb modifer， ing到底是行还是不行咧
