看不懂method的用法，求指教

下面两个题是08语法笔记上给出的一个关于method的用法的解释
(1)method of/for (doing) something优于 the method to：
137. Coronary angiography, a sophisticated method for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses x-rays to observe cardiac function.

(A)for diagnosing coronary disease involving the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses

(B)for diagnosing coronary disease involving the introduction of a dye into the arteries of heart, is now administered selectively, because of using

(C)for diagnosing coronary disease, involves the introduction of dye into the arteries of the heart and is now administered selectively, because it uses

(D)to diagnose coronary disease that involves the introduction of a dye into the arteries of the heart, is now administered selectively, because it uses

(E)to diagnose coronary disease involving the introduction of a dye into the arteries of the heart, which is now administered selectively, uses

Key: C

(2) 但是method的内容则可以用动名词表示：the method/way is to do…

OG12-11. There are several ways to build solid walls using just mud or clay, but the most extensively used method has been the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid in the wall in mud mortar.

(A) the forming of bricks out of mud or clay, and, after some preliminary air drying or sun drying, they are laid

(B) forming the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them

(C) having bricks formed from mud or clay, and, after some preliminary air drying or sun drying, they were laid

(D) to form the mud or clay into bricks, and, after some preliminary air drying or sun drying, to lay them

(E) that bricks were formed from mud or clay, which, after some preliminary air drying or sun drying, were laid

Key: D (以平行判题)

可是在第一个例子里的method 跟第二个例子里的method有什么差吗？为什么我看不出来，求大牛们指点下啊？为什么第一个用for doing 好，第二个是迫于选项所以选了D吗？如果有了一个 是forming 然后laying的选项，是不是就得选这个了？

我觉得第一个跟第二个里面的method没有什么差别的，都是作“方式，方法”讲
但是因为第二题主要的考得是平行，used method后面的内容跟前面的to build以及后面的to lay平行，所以在这里用to form要比用forming更好一些。
恩，也就是说一般情况下还是用methof of/for doing sth. ， 但是如果句子中出现了一些特殊情况的话就用to do（换句话说也就是method to do的用法不错，不能用它来直接排除选项）
个人意见~仅供参考哈

yidiyuehans

第一个是用of doing/for doing说明method的目的，第二个是用不定式说明method的内容

mudiduanger

恩~第一种用法是最常见的，朗文牛津词典上都列举了        但是关于to

do的话，我觉得也可以表目的吧，一定要是method的内容吗？之前看到过一个

句子：Plan a method to collect data for a specific tourism purpose.
我觉得这里的method后面的to ....好像是在说目的啊 ：筹划一个方法来.....
请问这个是为什么呢？

按LZ的说法，那么表示method本身的目的用for 或of, 而用method去完成某件事情得时候就还是用to do 吗？我一开始读着也是觉得第一个表目的，但是蓦然想到，表目的必须TO啊,仔细琢磨下，是不是这样，use this method to do sth, a method for doing sth 那么 there is a method to do sth算对或错啊?呼唤版主好人做到底啊……
