A transport layer protocol usually has several responsibilities.One is to create a process-to-process communication;UDP uses (71) numbers to accomplish this.Another responsibility is to providecontrol mechanisms at the transport level.UDP does this task at a very minimal level.There is no flowcontrol mechanism and there is no (72) for received packet.UDP, however,does provide errorcontrol to some extent.If UDP detects an error in the received packet,it will silently drop it.
The transport layer also provides a connection mechanism for the processes.The (73) must be able to send streams of data to the transport layer.It is the responsibility of the transport layer at (74) station to make the connection with the receiver,chop the stream into transportable units,numberthem,and send them one by one.It is the responsibility of the transport layer at the receiving end to waituntil all the different units belonging to the same process have arrived,check and pass those that are (75) flee,and deliver them to the receiving process as a stream.

It’s interesting that the arrival of snow has effect on people in different countries. For some countries it is an important happening to celebrate each year, while for others a catastrophe(灾害) or even a wonder.

  But there are countries between these two kinds that normally expect snow some time over the winter months, but never receive snow regularly or in the same quantities every year. Britain is one of them, for which the arrival of snow quite simply causes problems. Within hours of the first snowfalls, however light, roads are blocked, trains and buses have to stop in the middle of the way. Normal communication is affected as well: telephone calls become difficult and the post immediately takes more time than usual. And almost within hours, there are also certain shortages----bread, vegetables and other things-----not because all these things can no longer be produced or sent to shops, but mainly because people are frightened and go out and store up with food and so on…just for fear that something bad should happen.

  But why does snow have this effect? After all, the Swiss, the Austrians and the Canadians don‘t have such problems. It is simple because there is not enough planning and preparation. We need money to buy equipment to deal with snow and ice. To keep the roads clear, for example, requires snow-ploughs(扫雪机) and machines to spread salt. The reason why a country like Britain does not buy snow-ploughs is that they are used for a few days in any one year, and the money could be more useful in other things such as hospital, education, helping the old and so on..

 小题1:According to the writer, Britain is a country ________.

A.which has regular snow

B.which is not well prepared for snow

C.for which snow is a catastrophe

D.for which snow is a wonder  小题2:After a few hours’ snowing there are often some shortages of food because ______.

  A. shops have closed down B. people buy as much as they can

  B. farmers cannot produce any more D. people eat more vegetables in winter

  小题3:The words "two kinds" in the passage mean the countries ______.

A.which have weather as yearly happening to celebrate or as rare(少见) weather

B.which either have heavy snow or light snow

C.to which snow either causes problems or no problems

D.which either have snow-ploughs or no snow-ploughs
