Passage 2

If we were asked exactly what we were doing a year ago, we should probably have to say that we could not remember. But if we had kept a book and had written in it an account of what we did each day, we should be able to give an answer to the question.

It is the same in history. Many things have been forgotten because we do not have any written account of them. Sometimes men did keep a record of the most important happenings in their country, but often it was destroyed by fire or in a war.Sometimes there was never any written record at all because the people of that time and place did not know how to write. For example, we know a good deal about the people who lived in China 4,000 years ago, because they could write and leave written records for those who lived after them. But we know almost nothing about the people who lived even 200 years ago in central Africa, because they had not learned to write.

Sometimes, of course, even if the people cannot write, they may know something of the past. For most people are proud to tell what their fathers did in the past. This we may call “remembered history”. Some of it has now been written down. It is not so exact or so valuable to us as written history is, because words are much more easily changed when used again and again in speech than when copied in writing. But where there are no written records, such spoken stories are often very helpful.

34、Why do we know very little about the central Africa 200 years ago?

(71) [Customer Relationship Management (CRM) provides your company with new ways of better understanding and serving your customer.] In July 1998, when Intel began taking orders over the Internet, it also premiered a new Web-based system to deliver confidential documents to its B2B direct customers.

(72)[This service, known as Information Desk, along with other new Web-based information delivery services, has enabled the company and its direct, indirect and channel customers to work together more efficiently.] In Intel’s case, there were several reasons for deploying CRM, including:

With Web-based information delivery, everyone can get important information at the same time no matter where they are located.

(73)[The first release of Intel’s information delivery system slashed document delivery time from as much as two to three weeks to an average of three days. Now, it’s a matter of minutes.]

Extend reach without adding staff. Intel has added services to upwards of 75,000 global resellers.

(74)[As a result of getting confidential documents faster, three-fourths of Intel’s direct customer engineers shaved a week or more off their product development cycle.]

When it came to designing the system, Intel used best-of-breed, off-the-shelf applications and modified them to meet the needs of their customers. Indirect customers received an lectronic Design Kit (EDK) to help develop their own products and solutions.

(75) [And because CRM is a field in which new applications appear frequently, it was important to develop a flexible software architecture and an agile hardware infrastructure.] Intel runs its CRM systems on dual and 4-way Intel-based servers, with back-end databases distributed over 8-way Intel-based servers. This gives the company a powerful, flexible and highly available infrastructure.
