Today, most countries in the world have canals. Many countries have built canals near the coast, and parallel【C1】______the coast. Even in the twentieth century, goods can be moved more cheaply by boat than by any other means of transport. These【C2】______make it possible for boats to travel between ports along the coast without being【C3】______to the dangers of the open. Some canals, such as the Suez and the Panama, save ships weeks of time by making their voyage a thousand miles shorter. Other canals permit boats to reach cities that are not【C4】______on the coast, still other canals drain lands where there is too much water, help to【C5】______fields where there is not enough water, and furnish water power for factories and mills. The size of a canal【C6】______on the kind of boats going through it. The canal must be wide enough to permit two of the largest boats using it to pass each other easily. It must be deep enough to leave about two feet of water【C7】______the keel of the largest boat using the canal. When the planet Mars was first observed through a telescope, people saw that the round disk of the planet was crisscrossed by a【C8】______of strange blue-green lines. These were called "canals" because they looked the same as canals on earth【C9】______are viewed from an airplane. However, scientists are now certain that the Martian phenomena are really not canals. The photographs【C10】______from space-ships have helped us to discover the truth about the Martia"canals".

【T1】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.【T2】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 the following article, Intel explains how it decided a CRM system could benefit the company. In Intel's scale, 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. 【T3】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. 【T4】As a result of getting confidential documents faster, three-fourths of Intel's direct customer engineers saved a week or more off their product development cycle.When it came to designing the system, Intel used best-of-breed, off-the-shelf applies and notified them to meet the needs of their customers. Indirect customers received an Electronic Design Dot(EDK)to help develop their own products and solutions. 【T5】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.
