What a piece of work is a man! How noble in reason! How infinite in faculty! These words are uttered by the hero in Shakespeare's Othello.

A . The access layer is the initial point at which traffic enters the network. Traffic is marked （orremarked） at Layers 2 and 3 by the access switch as it enters the network， or is "trusted" that it isentering the network with the appropriate tag B . No traffic marking occurs at the core layer. Layer 2/3 QoS tags are trusted from distributionlayer switches and used to prioritize and queue the traffic as it traverses the core C . Traffic inbound from the access layer to the distribution layer can be trusted or reset dependingupon the ability of the access layer switches. Priority access into the core is provided based onLayer 3 QoS tags D . IP precedence， DSCP， QoS group， IP address， and ingress interface are Layer 2 characteristics that are set by the access layer as it passes traffic to the distribution layer. Thedistribution layer， once it has made a switching decision to the core layer， strips these off E . MAC address， Multiprotocol Label Switching （MPLS）； the ATM cell loss priority （CLP） bit， theFrame Relay discard eligible （DE） bit， and ingress interface are established by the voicesubmodule （distribution layer） as traffic passes to the core layer F . The distribution layer inspects a frame to see if it has exceeded a predefined rate of trafficwithin a certain time frame， which is typically a fixed number internal to the switch. If a frame isdetermined to be in excess of the predefined rate limit， the CoS value can be marked up in a waythat results in the packet being dropped

Most Americans stop working at the age of sixty-five or seventy and retire. Because work is such an important part of life in American culture, retirement can be very difficult for Americans. Retirees often feel that they are useless and unproductive. Of course, some people are happy to retire, but leaving one's job, whatever it is, is a difficult change, even for those who look forward to retiring. Retirement can also bring financial problems. Many people depend on Social Security checks every month. During their working years, employees contribute a certain percentage of their salaries to the government. Each employer also gives a certain percentage to the government. When people retire, they receive this money as income. Sometimes these checks do not provide enough money to live on, because prices are prone to increasing, a process known as "inflation". Senior citizens, those over sixty-five, typically have to have savings in the bank or other retirement plans to make ends meet. In addition, many senior citizens have to change their lifestyles after retirement. They have to spend carefully to be sure that they can afford to buy food, fuel and other necessities(必需品). Of course, many senior citizens are happy with their retirement. They have time to spend with their families or to enjoy their hobbies. Some continue to work part-time, others do volunteer work. Some, like those in the Retired Business Executives Association, even help young people to start new businesses. Many retired citizens also belong to "Golden Age" groups. These organizations plan trips and social events. There are many other opportunities for retirees. Which of the following could be the best title of the passage？ A．Golden Age Groups B．The American Opinion of Work C．The Importance of Work in America D．The Problems of Retirement in America

Next you will find a good builder and together with the builder you will work out a plan. The builder will draw the plan. It will show the number of rooms their position and size and other parts such as windows doors and electric outlets(电插座). The builder will work out how much money is needed to build your house. He will work out the cost of the wood bricks the glass and everything else that must be used in building the house. Later on when he starts to build this estimate(预算) must be corrected and revised(修订). His estimate is based on existing prices but prices of such things may change and many other things may happen between the time when he makes the estimate and the time when he builds the house. When the builder gives his estimate you may wish to change your plan. (You may also wish to change your builder if his estimate is too high!) You may find that the house you wanted at first costs too much or that you can spend a little more and add something to your plan. The builder&39;s estimate depends on the plan but the final plan depends on the builder&39;s estimate. 1.The best title of this passage is_______.
