解析：选C　写作意图题。纵观全文可知，文章第一段指出人类并没有像很多思想家预料的那样取得长足进步，第二、三段说明了原因，即这是因为科技的发展没有与道德情感相联系，第四段说明即使我们不能完全实现道德理想，但有了它的指导我们也能取得进步。由此可知，本文主要谈论了道德理想在人类进步中的重要性。故答案选C。

　　C

　　In 1957, Max Vernon Mathews wrote the first computer program called Music, which enabled a computer to create sound and play it back. He was then working as an engineer at Bell Laboratories in New Jersey. It enabled a large IBM computer to play a seventeen­second piece of music he had written.

　　The computer was so slow that it took an hour to play the seventeen­second piece of music. So Mathews moved the work to a tape player to play the music at a normal speed. He later said that the sound quality of the musical notes was not great, but the technical importance of the music was huge.

　　The science­fiction writer Arthur C. Clarke visited Bell Laboratories in the 1960s. He heard a computer "sing" the song Daisy Bell on devices (设备) and learned about the programs developed by Mathews and other engineers. Clarke noted this technology in his book 2001: A Space Odyssey, which was later made into a movie.

　　Mathews continued creating other versions of the Music program. He became interested in how computers could help musicians outside recording studios. The Groove program he developed was the first computer program made for live performances.

　　He also developed an electronic device he called the Radio Baton, which looks like two drum sticks. It enables the user to control the speed and sound levels of orchestral music (管弦乐) played on a computer by moving the two sticks on a special electronic surface.

　　Mathews said he believed modern musicians were not making full use of the power of computer music. He said a violin always sounds like a violin. But with his Music, the way a violin sounds is unlimited. He did not want computer sounds to replace live music, but he hoped computers would one day be considered serious instruments.

　　语篇解读：本文是记叙文。Max Vernon Mathews把音乐与计算机结合起来，创造了魅力无穷的计算机音乐。

　　28．Why did Clarke visit Bell Laboratories?

　　A．To make his book into a movie.

　　B．To help Mathews develop Music.

C．To satisfy his own curiosity about music.
