B.packets

C.frame

D.information

答案

参考答案：A

解析：

MIDI使人们能够使用多媒体(multimedia)计算机和电子音乐设备。实际上，MIDI由三个部分组成：通信“协议(protocol)”、硬件接口和被称为标准MIDI文件的发布格式(format)。在WWW的内容中，最令人感兴趣的部分是音频(Audio)格式。从原理上看，MIDI文件包含了一系列MIDI协议消息。然而，当MIDI协议消息(messages)被存储在MIDI文件时，事件也都被加上时间戳，以便能按正确的顺序进行回放。目前，通过MIDI文件传递音乐是MIDI最主要的应用。

Questions 19-25

·For questions 19-25, choose the correct answer A, B, C and D.
·Markyour answers on the Answer Sheet.
In my early childhood I received no formal religious education. I did, of course, receive the ethical and moral training that moral and conscientious parents give their children. When I was about ten years old, my parents decided that it would be good for me to receive some formal religious instruction and to study the Bible, if for no other reason than that a knowledge of both is essential to the understanding of literature and culture.
As lapsed Catholics, they sought a group which had as little doctrine and dogma as possible, but what they considered good moral and ethical values. After some searching, they joined the local Meeting of the Religious Society of Friends. Although my parents did not attend Meetings for Worship very often, I went to First Day School there regularly, eventually completing the course and receiving an inscribed Bible.
At the Quaker school, I learned about the concept of the "inner light" and it has stayed with me. I was, however, unable to accept the idea of Jesus Christ being any more divine than, say, Buddha. As a result, I became estranged form the Quakes who, though believing in substantially the same moral and ethical values as I do, and even the same religious concept of the inner light, had arrived at these conclusions from a premise which I could not accept. I admit that my religion is the poorer for having no revealed word and no supreme prophet, but my inherited aversion to dogmatism limits my faith to a Supreme Being and the goodness of man.
Later, at another Meeting for Worship, I found that some Quakers had similar though not so p reservations about the Christian aspects of their belief. I made some attempt to rejoin an organized religious group, I did not wish to become one again. I do attend Meeting for Worship on occasion, but it is for the help in deep contemplation which it brings rather than any lingering desire to rejoin the fold.
I do believe in a "Supreme Being" (or ground of our Being, as Tillich would call it). This Being is ineffable and not to be fully understood by humans. He is not cut off from the world and we can know him somewhat through the knowledge which we are limited to the world. He is interested and concerned for humankind, but on man himself falls the burden of his own life. To me the message of the great prophets, especially Jesus, is that good is its own reward, and indeed the only possible rewards are intrinsic in the actions themselves. The relationship between each human and supreme Being is an entirely personal one.
It is my faith that each person has this unique relationship with the Supreme Being. To me that is the meaning of the inner light. The purpose of life, insofar as a human can grasp it, is to understand and increase this lifeline to the Supreme Being, this piece of divinity that every human has. Thus, the taking of any life by choice is the closing of some connection to God, and unconscionable. Killing anyone not only denies them their purpose, but corrupts the purpose of all men.

It can be inferred from the passage that ______.

A．the author views the inner light as uniquely an attribute of Quakers

B．the Catholics are not concerned with killing

C．the author’s parents found Catholic religious views unsuitable or inadequate

D．Buddhist belief is as congenial to the author as Quaker belief
