by开始的句子,必须是要能够符合逻辑主语一致性的==>by doing sth, sb do sth 1. 因为句首是by recording,所以后面的划线内容就应该也是doing sth,而不是DE的结构,不符合平行的原则 2.在ABC的区别就是 the noise not/that the noise was not/the noise not to be, 到底用哪个就要看未划线的部分:continuous but consisted of ==>这里是svo but vo的结构,既然but后面是consisted of,是but did sth 的过去时的结构,所以but前面也必须有verb存在而AC都没有,B不但有verb(be动词),还很好的对应了过去时的结构was,所以B正确
