间的推移，如：as time goes on, our vocabulary is enlarging gradually.

Diverse: a 不同的，各种各样的，相当于various.如：

New York is a very culturally diverse city.

5. What developed was a music readily taking on various forms and capable of an almost limitless range of expression. (p2)

译：音乐的很快发展成为具有多种形式并且几乎具有无限的表现力。

句子分析：主语：What developed，后面是一个系表结构，readily taking on various forms and capable of an almost limitless range of expression分别是现在分词短语和形容词短语做定语，修饰music.另外：take on意思：具有；be capable of doing sth有能力做某事。

6. Electronics did, in fact, make possible sounds that no instrument up to that time could produce. (p3) 译：事实上，电子学的确可以制作出到那时为止乐器所发不出的声音。

句子分析：did make是谓语的强调结构，possible是宾补，提到宾语sounds以及定语从句之前是国考的重要考点，目的是为了避免结构的头重脚轻现象。（在下一句话中我们还会见到相同用法。）

7. Electronic amplifiers also made possible a fantastic increase in volume, the music becoming as loud and penetrating as the human ear could stand, and thereby achieving a total effect, so that instead of an audience of passive listeners, there were now audiences of total participants, feeling the music in all of their senses and all of their bones. (p3)

译：电子扬声器也使得在音量方面能够有意想不到的提高，音乐在人类耳朵所能承受范围内变得响亮，具有穿透力，由此表达了一种完美的效果，所以听众已不是被动的听众，现在的听众是完全投入的听众，他们在全身心感受着音乐。

句子分析：本句话非常复杂，可分为四个层次：第一层次是主句：Electronic amplifiers also made possible a fantastic increase in volume；第二层次从the music becoming直至句尾是现在分词的独立主格结构，做伴随状语。第三层次：so that引导的结果状语从句；第四层次从feeling到句尾为现在分词短语，又是分词做伴随状语。

8. With records at home, listeners imitated these lighting effects as best as they could, and heightened the whole experience by using drugs. (p4)

译：家里有了唱片，听众尽力模仿舞厅灯光效果并通过使用药物以加强整体感受。

句子分析：With records at home方式状语；imitated和heightened两个并列谓语动词；as best as one could尽力做某事,如： I sear I will teach him a lesson as best as I could。
