From English into Chinese (5%)

Discount means that sellers offer buyers a certain percentage of reduction on the original price. When competition in the market is fierce, discount will help to improve sellers' competitiveness. There are different kinds of discount, for example, quantity discount, seasonal discount and exceptional discount. The specific amount or percentage of discount varies in different situations. The percentage of discount can be clearly written down in a contract if the seller and the buyer have reached an agreement.

The amount of discount is usually deducted from the buyers' payment.

When the system upon which a transport entity is running fails and subsequently restarts,

the(66)information of all active connections is lost. The affected connections become half-open, as the side that did not fail does not yet realize the problem.The still active side of a half-open connection can close the connection using a(67)timer. This timer measures the time the transport machine will continue to await an(68)of a transmitted segment after the segment has been retransmitted the maximum number of times. When the timer(69), the transport entity assumes that either the other transport entity or the intervening network has failed. As a result, the timer closes the connection, and signals an abnormal close to the TS user.In the event that a transport entity fails and quickly restarts, half-open connections can be terminated more quickly by the use of the RST segment. The failed side returns an RST i to every segment i that it receives. When the RST i reaches the other side, it must be checked for validity based on the(70)number i, as the RST could be in response to an old segment. If the reset is valid, the transport entity performs an abnormal termination.

A．data

B．state

阅读下面的短文，回答问题 [When an IP packet arrives at a router, generally the router loo

ks at the destination address of the packet, and forwards the packet to one of its network interfaces. The forwarding decision is usually done by looking up the destination address from another data structure called a forwarding table. The forwarding table is created by the router using the routing table and possible routing policies existing in the router. The router then creates a table where it lists which networks are accessible through which of the router’s network interfaces. An IP router looks at every IP packet individually and does the forwarding decision on a packet-by-packet basis. If something changes in the router’s routing table, a packet can take a different route from a preceding packet even if it has the same destination.] From the paragraph above，we can see that the router （） a forwarding table according to the routing table and possible routing policies existing in the router. When an IP packet arrives at a router, the （） part of packet is normally checked by the router. An IP router checks every IP Packet individually and makes the forwarding decision based on （）.

A．is generating B．generate C．is generated D．generates A．forwarding table B．network interfaces C．routing policies D．destination address A．the destination address and network interfaces B．forwarding table and network interfaces C．the destination address and forward table D．routing policies and routing table

Software entities are more complex for their size than perhaps any other humanconstruct, b

Software entities are more complex for their size than perhaps any other human construct, because no two parts are alike (at least above the statement level). If they are, we make the two similar parts into one, a （）, open or closed.In this respect software systems differ profoundly from computers, buildings, or automobiles, where repeated elements abound. Digital computers are themselves more complex than most things people build; they have very large numbers of states.This makes conceiving, describing, and testing them hard.Software systems have orders of magnitude more（）than computers do. Likewise, a scaling-up of a software entity is not merely a repetition of the same elements in larger size; it is necessarily an increase in the number of different elements.In most cases, the elements interact with each other in some（）fashion, and the complexity of the whole increases much more than linearly. The complexity of software is a(an) （）property, not an accidental one.Hence descriptions of a software entity that abstract away its complexity often abstract away its essence.Mathematics and the physical sciences made great strides for three centuries by constructing simplified models of complex phenomena, deriving, properties from the models,and verifying those properties experimentally.This worked because the complexities（）in the models were not the essential properties of the phenomena.It does not work when the complexities are the essence. Many of the classical problems of developing software products derive from this essential complexity and its nonlinear increases with size.Not only technical problems but management problems as well come from the complexity.

WWW is popular for its multimedia transmission and friendly(71). Although the speed of network has been improved considerably in recent years, the rapid(72)of using the Internet, the inherited character of delay in the network and the Request/Response working mode of WWW still make the Internet traffic very(73)and give no guarantee on the Quality of Service. Because HTTP has no states, the web server cannot know the users' demand and the users' requests cannot be predicted Taking advantage of a cache mechanism and the time locality of WWW accesses, the browser can preserve the documents ever accessed in the local machine. By this means, for the documents in the local cache, the browser does not need to send the requests to the remote server or to receive the whole responses from the remote one Pre-fetching uses the space locality of accesses First, the users' access requests are predicted according to the users' current request. Secondly, the expected pages are fetched into the local cache when the user is brow sing the current page. Finally, the users can access these pages downloaded from the local cache. And this can reduce the access delay to some degrees. Pre-fetching is one kind of active caches that can cache the pages which are still not requested by the user. The application of pre-fetching technology in the web can greatly reduce the waiting time after users have sent their requests. This paper brings forward an intelligent technique of web pre-fetching, which can speed up fetching web pages. In this technique, we use a simplified WWW data model to represent the data in the cache of web browser to mine the association rules. We store these rules in a knowledge base so as to(74)the user's actions. In the client sides, the agents are responsible for mining the users' interest and pre-fetching the web pages, which are based on the interest association repository. Therefore it is(75)for the users to speed up the browsing.
