公共英语五级分类模拟题Job and OccupationUnit 1Part IWorkplace EthicsIntegrity is priceless. So many have proffered various definitions for integrity but for the purpose of clarity and simplicity, I will adopt the Advanced Oxford Dictionary deflnition, which describes integrity as the n quality of being whole and undivided". In other words, this means you are who you are anytime, anywhere regardless of who is watching you or not. Integrity means you do not need the presence of your boss to get you to do what you should do. You only need the presence of your conscience. Integrity means you can work with little or no supervision. Integrity means your word is your bond. The workplace would definitely be more productive if everyone kept to his or her word. Your inconsistency at keeping your word in no time earns you a negative reputation in the workplace.One vital fact we cannot afford to miss out when discussing integrity, is integrity to self. Unless I am able to meet the commitments I make to myself, it would only amount to self-deceit to think I can make external commitments. If I cannot will myself to write that document at the exact time I said I would, there is every likelihood I would not make the meeting at the time I said I would. Integrity must be from within. I must be able to will what I do and do what I will. The standard is as declared by Benjamin Franklin, H Resolve to perform what you ought; perform without fail what you resolve.H This is integrity; the foundation of sound ethics.We shall continue to dissect some basic principles on ethics and how they affect your place in the workplace and your ultimate fulHllment in life.The pursuit for success, the craving for wealth, the riotous desire for fame and popularity, the quest for control and power are the forces that have long controlled the thoughts and actions of men. A new generation arises, another fades away, but not without passing on the baton as the rat race continues. The memory of the former evaporates with their pursuits, some linger for a while but are soon lost in the busyness of another generation. The state of man and our brief sojourn on the earth were aptly captured in the words of a sage, "men live like they will never die and die like they never lived". However, in all this, I have found few wise men who have permanently etched their marks in the hearts of men and even when we feign ignorance, history reminds us of their achievements and contributions. Generations yet unborn will be reminded of this select few. Some call it leaving a legacy. I call it living forever.Some of us are determined, goal oriented and focused, some just drift along hoping it all goes well. Whichever our stance may be, let us remember that in no time we will fade away amidst our pursuits and after we are gone the evidence that we ever lived will be determined by the amount of impact we were able to make on our society, and the service we were able to render to humanity. As you go about your work today, hold nothing back, give your all, appreciate your boss and colleagues, do not withhold a kind word, continue to exude encouragement, forgive freely, let no issue go unresolved, strive towards peace with yourself and your fellow man. This is the attitude that made the greats live forever, imbibe them and you would too.Handle slow times effectively. Every now and then, you will get the opportunity to3 WhichA.ItB.ItC.It It Questionswords . true?in life. MORE THAN threebe ahead of your schedule. No new deadlines to meet, all reports have been made and filed and you have little work and a lot of time. The way you handle such times will reveal a lot about your character. More often than not, what most employees would rather do at such downtimes is quite predictable. Some would choose to play a game of poker on the computer, read a novel or spend time chatting on the phone or the internet.It takes an exceptional employee to make prudent use of slow times and light workload situations. Ethics demand we not only use such times for our own personal improvement and fulfillment but also look out for more ways to be effective on the job. Start something, develop a new idea, reach beyond you confinements to other units that may need an extra help. However, carefully looking at it, there will never be a time when you have nothing to do. The workplace is never dormant; there would most likely be something you have deferred until a later date. Little details such as cleaning out your drawer, return a call, and writing a memo could take such times. Here are some ways you can make good use of light workload situations. When our workload is lighter, it is an opportunity for us to dig in a little deeper and come up with new ideas. It is a chance to conduct a personal systems review, to evaluate our performance and if possible increase the standard. We can make an inventory of our talents and gifts and focus on how best we can maximize our potential. We can begin to spend time updating official records, go through our desks, clean out and organise all those old files. One may be surprised at the amount of information contained in them.ComprehensionQuestions 1--3 Choose the best answer.1、The word integrity is more about .A.the consistency of one1s behaviors in the workplaceB.the positive attitude toward one1s work under direct supervisionC• the workplace productivityD・ one's reputation in the society2、 One strong indicator of integrity isA.working out documents by the deadlines B• to do what one would like to doC• the combination of resolution and the ability to fulfill it D• to meet the required standard in the workplaceof the following statements about ethics is NOT isclosely related to integrity.may determine one1s place in the workplace•may have something to do with one1s fulfillment islargely need-driven.4--7 Answer the following questions by using NO4、What are the things that human beings have never stopped pursuing?5、What are the reasons why those great figures in history would never fade away with time?6、What can prove our existence in this world after we have passed away?7、What can we do to die without being forgotten?Questions 8- -11 Complete the following sentences with NO MORE THAN three words for each blank.8^ One' s character can be reflected in the way he .9、Only those who are can make good use of their time when they are ahead of their schedule.10> When in , we can further explore our potential.Old files may have a lot of .Exercise 1 Use of EnglishRead the following text and fill each of the numbered spaces with ONE suitable word.Karoshi -- Worked to DeathJapan 1s rise from the devastation of World War II to economic prominence between 1945 and 1975 was not without human cost • People cannot work for ten or twelve hours a day six and seven days a week, year after year, 12 suffering physically as well as mentally.But during the first three postwar decades no one 13 any special attention to the 14 than usual number of men in their 40s and 50s who died of brain and heart ailments, most often 15 acute cardiac insufficiency and subarachnoid hemorrhage.It was not 16 the latter part of the 1980s, when several high-ranking business executives who were still in their prime 17 suddenly died without any previous 18 of illness, that the news media began picking up on what appeared to be a new 19 .This new phenomenon was quickly labeled karoshi , 20 "death from overwork", and once it had a 21 and its symptoms were broadcast far and wide, it quickly became obvious that 22 was experiencing a virtual epidemic•According to Labor Ministry 23 there had been only twenty-one cases of 24 in 1987, twenty-nine cases in 1988 and thirty cases in 1989. But a liaison council of attorneys established in 1988 to monitor 25 from overwork estimated in 1990 that over 10,000 people were 26 each year from karoshi •Most of the 27 of death from overwork had been putting in more than one hundred hours of overtime each.

But still many others countered that the problem of unemp 1 oyment will get worse if the policy is put into practice. What is your opinion on that?Unit 2Part IMyth & RealityForget all the talk of equal opportunity. European women can have a job — but notHere's a pop quiz on gender equality. In which part of the world are women most likely to reach the highest rungs of power? Choice A offers new moms 12weeks of maternity leave, almost no subsidized child care, no paid paternity leave and has a notoriously hard-driving business culture. Choice B gives them five months to three years of paid time off from their jobs after having kids. Millions put their offspring into state-sponsored day-care centers for several hours a day. Government agencies, full of female directors and parliamentarians, protect workers at the expense of business and favor a kinder, gentler corporate culture. So which place is better for women who want to make it to the top? If you guessed A, the United States, you'd be right. If you chose B, Europe, think again.It sounds impossible, but it's true. For all the myths of equality that Europe tells itself, the Continent is by and large a woeful place for a woman who aspires to lead. According to a paper published by the International Labor Organization this past June, women account for 45 percent of high-level decision makers in America, including legislators, senior offlcials and managers across all types of businesses. In the U.K., women hold 33 percent of those jobs. In Sweden — supposedly the very model of global gender equality - they hold 29 percent.Germany comes in at just under 27 percent, and Italian women hold a pathetic 18 percent of power jobs. These sad statistics say as much about Europe's labor markets, lingering welfare state policies and corporate leadership as they do about its attitudes toward women. Ifs not that European women are stuck in the house. The real problem is that Europe has been consistently unable to tap the highest potential of its female workers, who represent half of college graduates in most countries. Women, it seems, can have a job — but not a high-powered career.Why is this? Simply put, Europe is killing its women with kindness ― enshrined, ironically, in cushy welfare policies that were created to help them. By offering women extremely long work leaves after children, then pushing them to take the full complement via tax policies that discourage a second income, coupled with subsidies that serve to keep them at home, Europe is essentially squandering its female talent Not only do women get off track for long periods, many simply never get back on. Nor have European corporations adapted to changing times. Few offer the flextime that makes it easier for women to both work and manage their families. Instead, women tend to get shuffled into part- time work, which is less respected and poorly paid. Those who want to fight discrimination find themselves hamstrung by laws favoring employers.Among Europe's myriad problems, this one is huge — with ramifications way beyond gender relations. In fact, it wouldn't be an exaggeration to say that Europe's future hinges on it. n We have got to get more women into the labor market/* says Vladi mir Spidla, the EU commissioner of Employment and Social Affairs. Declining birthrates and aging populations threaten the financial stability of almost all European nations, he explains. With a massive skills gap and pension crisis looming, the Continent must bring in more high-level workers. Immigration ― the main solution thus far- presents obvious cultural challenges. Taking better advantage of existing female populations is an obvious answer.Yet consider the "female friendly" policies touted by many Europeans as solutions to the work-life dilemma, among them those legendary maternity leaves. Any number of studies, including some by the OECD and the ILO, has shown how excessively long leaves can derail women's career prospects, often permanently. Employers areunderstandably reluctant to hire and promote someone who may absent herself for years on end, often more than once. n Being a potential mother becomes an obstacle for women in certain types of jobs, and that is the case all over Europe/1says ILO labor sociologist Manuela Tomei. Removing one's wedding ring for job interviews has thus become commonplace. So have probing questions. "Your family plans come up at every single job interview/1says Sasha Buehler, a Munich film buyer. 'Tve had to promise potential employers that I won't get pregnant." While questions like this might elicit a lawsuit in the United States, European women are less likely to fight back. Europe doesn't allow class-action suits and, outside of the public sector, the burden of proof in a discrimination cage still falls on the individual rather than the corporation, making it incredibly difficult for a single person to initiate and win a case.Add to this the fact that Europe's business culture is still more hierarchical and less flexible than America's. Women tend to thrive in less formal, more entrepreneurial environments where they can help set the rules, as in the United States. If Europe is to tap into the full potential of its underemployed female work force, says Valerie Gauthier, associate dean of the HEC School of Management, a business - school in Paris, it will have to similarly modernize its labor markets: "The government should support more entrepreneurs and encourage them to set their own work environments, creating situations better suited to the needs of women."ComprehensionQuestions 1--3 Choose the best answer.34、In Europe .A.it1 s particularly difficult for those women who are in their progress to senior positionsB.women are kindly treated in enterprises when they are trying to get back to regular job after having kidsC.it1 s a long-established tradition that men and women are equally paid D •it1 s more likely for women to reach high positions in government agenciesthan it is in America 35> The statistics f rom the paper publ i shed byInternational Labor Organization suggest that •A.

Questions 8- -12 Complete the following sentences with NO MORE THAN three words for each blank.41、Europeans suppose that could help women work and manage their familiesas well.42^ Businesses wouldn 11 want to employ women because they can not work when theyare .43、It would be much easier for women to initiate a discrimination case in Europeif it changes it1s legal system and permits .44、The of Europe is more rigid and puts more emphasis on classes.45、In order to take better advantage of its female talent, Europe should learnfrom the United States and .Part IIExercise 1 Multiple MatchingAnswer questions 1- -10 by referring to the following passages • Answer each question by choosing A, B, C or D.(Note: When more than one answer is required, these may be given in any order• Some choices may be required more than once•)A = ARTICLE 1B = ARTICLE 2C = ARTICLE 3Which articledifferentiates two different forms of document, both of which give information about the tasks of a role, only that one is more detailed than another?explains what necessitate(s) job analysis?points out that job descriptions for organizations of different size could be different?elaborates the preparatory activity of a good job description?states that job descriptions could fail to function as planned unless it1s carefully worded?indicates that job descriptions can not only commit one to a role but may also allow him to negotiate with his supervisor about his job responsibilities?observes that efficiency of a small business is largely based on an accurate job analysis?gives the longest list of the functions of job descriptions?defines different terms involved in job description development?says that a proper job analysis and a good job description can protect small business from potential problems?1. _____2.3.4.5.6 . _____7.8.9.10.A ARTICLE 1First, let1s look at some terms. A job is a collection of tasks andresponsibilities that an employee is responsible to conduct . Jobs have titles . A task is typically defined as a unit of work, that is, a set of activities needed to produce some result, e . g. , vacuuming a carpet, writing a memo, sorting the mail, etc . Complex positions in the organization may include a large number of tasks, which are sometimes referred to as functions• Job descriptions are lists of the general tasks, or functions, and responsibilities of a position. Typically, theyalso include to whom the position reports, specifications such as the qualifications needed by the person in the job, salary range for the position, etc• Jobdescriptions are usually developed by conducting a job analysis, which includes examining the tasks and sequences of tasks necessary to perform the job. Theanalysis looks at the areas of knowledge and skills needed by the job. Note that a role is the set of responsibilities or expected results associated with a job• A jobusually includes several roles.Typically, job descriptions are used especially for advertising to fill an open position, determining compensation and as a basis for performance reviews. Not everyone believes that job descriptions are highly useful. Dr• John Sullivan points out numerous concerns about job descriptions that many other people have as well, including, e.g•, that too often job descriptions are not worded in a manner such that the employee 1 s performance can be measured, they end up serving as the basis for evaluation rather than performance, etc.B ARTICLE 2The cornerstone to any employment decision begins with job analysis. Job analysis is the most basic activity in human resource management. Accurate information on all jobs is necessary to efficiently direct and/or control the operations of a small business . Competition and equal employment opportunity legislation has made job analysis a mandatory organizational consideration for small businesses. Because human resources represent the largest cost item for most small businesses, managers must have current and systematized information on all jobs in order to produce products and services efficiently. The myriad of laws, guidelines, and court decisions concerning equal employment opportunity make job analysis necessary. Small businesses have been quite vulnerable on the issue of discrimination in employment practices. One way to defend employment practices is to conduct job analysis and prepare job descriptions • Job descriptions are the most visible output from job analysis - Comprehensive j ob descriptions developed from j ob analysis are used in selection, training, performance appraisal, and compensation. There are many formats used in preparing job descriptions.Job analysis is an in-depth study of a job and provides information for job descriptions. The job analyst will gather information about jobs through interviewing employees, observing performance of certain tasks, asking employees to fill out questionnaires and worksheets, and collecting information about a job from secondary sources such as the Dictionary of Occupational Titles ・The job analyst will write down the results of the analysis and review themwith the job incumbent. The documentation is then presented to the incumbent * s supervisor for review (often the incumbent's supervisor is the job analyst). The supervisor may add, delete or modify duties, knowledge, skills, abilities, and other characteristics. After supervisory approval is obtained, the documentation is forwarded through channels for final approval. A signed and dated job description is then prepared. This job description becomes the official record for this particular job.C ARTICLE 3Job descriptions are essential• Job descriptions are required for recruitmentso that you and the applicants can understand the role. Job descriptions arenecessary for all people in work. A job description defines a person1 s role and accountability. Without a job description it is not possible for a person toproperly commit to, or be held accountable for, a role • As an employee you may have or be given the opportunity to take responsibility for your job description. Itallows you to clarify expectations with your employer and your boss.The process of writing job descriptions is actually quite easy and straight-forward. Many people tend to start off with a list of 20〜30 tasks, which is okay as a start, but this needs refining to far fewer points, around 8〜12 is the ideal. Smaller organizations commonly require staff and managers to cover a wider or more mixed range of responsibilities than in larger organizations (for example, the H of f ice manager11role can comprise financial, HR, stock-control, scheduling and other duties)• Therefore in smaller organisations, job descriptions might necessarily contain a greater number of listed responsibilities, perhaps 15~16 . However, whatever the circumstances, the number of responsibilities should not exceed this, or the job description becomes unwieldy and ineffective.Any job description containing 20〜30 tasks is actually more like a part of an operational manual, which serves a different purpose. Job descriptions should refer to the operational manual z or to n agreed procedures11, rather than include the detail of the tasks in the job description. If you include task detail in a job description you will need to change it when the task detail changes, as it will often do. What would you rather change, 100 job descriptions or one operational manual?Exercise 2 SpeakingFor each of the following topics, you will have two minutes to prepare and then give a two-minute presentation.56、Exercise 3 WritingYou are expected to write at least 250 words about the following topic. 57> Competition in China f s job market has become increasingly intense especially forc ollege graduates. Many of them have to stay jobless after graduation • Many people attributed it to the expansion of university enrollment. Do you agree or disagree with this point of view?答案：Unit 1Part I1、AParagraph 1: In other words, this metals you are who you are anytime, anywhere regardless of who is watching you or not • 选项A中consistency一词与U匕句中anytime 与anywhere两词表达的意义相符。

If the interface configuredwith a VRRP backup group fails or any interface on the router fails,the VRRP backup group providesTrue FalseTrue63.By using VRRP, the backup router in a VRRP backup group immediately becomes the masterrouter after detecting a fault and instructs its attached hosts to perform a master/slave switchover accordingly. This ensures that services will recover within a short period of time.True FalseFalse64.The reliability of a product or a system is generally evaluated with the two indicators of Meantime to repair (MTTR) and mean time between failures(MTBF).True FalseTrue65.BFD detects the link status immediately after a BFD session is set up .if BFD parameters aremodified or deleted at one end of the BFD session,the other end will consider such a modification or deletion as a fault and services will be then affected, Therefore,exercise caution when modifying or deleting BFD parameters.True FalseFalse66.One CV packet per second is generated on the ingress LSR of the LSP and receivd by theegress LSR, this generation rate is low and allows no adjustment,hence,the CV packet is usually used for checking the availability of a common LSP.True FalseTrue67.BFD packets are classified into control packets and echo packets.True FalseTrue68.A BFD session is set up following the three-way handshake during which parameters for theBFD session are negotiated.

AS such,BFD and GR cannot be used together.True FalseFalse73.In OSPF,the process of calculating shortest path tree can be divided into two phases,calculatetransit node first,then calculate stub network.True FalseFalse74.In the process of calculating SPF tree,the cost from a node to root node equals to metriclisted in the Router LSA generated by the node.True FalseFalse75.BGP is an exterior

protocol number is 89True FalseTrue86.If the Router Priority of a router is set to 0,this router cannot be elected as a DR or a BDR.True FalseTrue87.On a non-broadcast network,OSPF has two operating modes:NBMA and P2MPTrue FalseTrue88.By default,the cost of an OSPF interface is related to interface bandwidth.The algorithm forcalculating the cost is:True FalseTrue89.On a broadcast network or an NBMA network,not all neighbors need to set upadjacencies.Therefore,the concept about the adjacency is applicable to only the broadcast network or the NBMA network.True FalseFalse90.The NBMA mode requires all the routers in the network to be fully connected:otherwise,itdoes not function.True FalseFalse91.When two routers exchange LSDB information by exchanging DD packets,a master/slaverelationship is established between the two routers,The router with a larger router ID is the master.True FalseTrue92.If both the ospf cost and bandwidth-reference commands are configured

long.True FalseTrue96.On a broadcast network or an NBMA network,a router with a higher Router Priority is electedas a DR.True FalseFalse97.The LS Sequence Number field is used to detect expired and duplicate LSAs,This field is asigned 32-bit integer and therefore the minimum LS Sequence Number is 0x80000000True FalseFalse98.The LSAs with the same LS Sequence Number and LS age are the same LSA.True FalseFalse99.ABRs of a Stub area do not flood type-5 and type-4 LSAs to the stub area.Therefore,the stubarea does not have the external AS routing capability.ABRs of the stub area advertise a default route to the stub area to guide packet forwarding to the external of the AS.True FalseTrue100.The ABR in a Totally Stubby area will not advertise Type-3,Type-4,and Type-5 LSAs to the Totally Stubby area.Instead,the ABR will advertise a default route to the Totally Stubby area to guide forwarding of packets destined for other areas.True FalseTrue101.The ABR of an NSSA will not advertise Type-4 and Type-5 LSAs to an NSSA but can import external routes into the NSSA.True FalseTrue102.Different from a Stub area,an NSSA supports Type-5 LSAs.True FalseFalse103.ABRs advertise link status information about connected non-backbone areas to the backbone area.The backbone area then advertises the routing information about the backbone area cannot be advertised to non-backbone ares.True

between BGP peers can protect them from Dos attacks.True FalseTrue111.In the VRP,by default,the routes imported by BGP are not automatically summarized.True FalseTrue112.Based on BGP route selection rules,a local route that is automatically summarized takes precedence over a local route that is manually summarized.True FalseFalse113.Once a BGP connection is established,a BGP speaker advertises all the optimal routes in the BGP routing table to its BGP peer.True FalseTrue114.Whatever changes occur in the BGP routing table,a BGP speaker advertises all the optimal routes in the BGP routing table to its BGP peerTrue FalseFalse115.In the VRP,by default,a BGP router automatically retransmits an Update packet to its BGP peer after the outbound routing policy of the BGP peer changes.True FalseTrue116.IGP routes can be installed into the BGP routing table by running either the network or import-route command.True FalseTrue117.In the VRP,by default,a BGP router does not automatically

attribute is actually a character string defined by using a regular expression.True FalseTrue127.Default routes between routers are a low-cost solution.this is because using default routes requires less system resources than maintaining a complete routing table.True FalseTrue128.An AS-path-filter uses the regular expression[0-9]+$ to indicate all as-path attributes.True FalseFalse129.Regular expressions can be used in both the community-filter and AS-path-filter to define the attribute mode used for route filteringTrue FalseTrue130.Route filtering can filter not only routing information but also link-status information.True FalseFalse131.For link-status routing protocols,filtering routes in the inbound direction actually cannot block the transmission of link-status information.the filtering effect is that routes cannot be injected into the local routing table but neighbors can still receive complete route status information and calculate complete routes.True FalseTrue132.All routing protocols can deliver default routes,supporting both forcible delivery and non-forcible delivery.True FalseFalse133.IF different routing protocols run on different networks and these networks need to share routing information,route importing can be usedTrue FalseTrue134.The route selection tool route-policy can filter and set BGP attributes based on pre-defined conditions.therefore,this tool is commonly used to define policies for BGP peers and often used in routeTrue FalseTrue135.When importing routes discovered by other routing protocols,a routing protocol may need to import only the routes that meet the conditions and set attributes of the imported routes to meet the requirement of the protocol,In such a case,a route-policy can be created.True FalseTrue136.Policy-based routing and routing policy affect the forwarding of data packets in different ways:A routing policy mainly controls packet forwarding,According to the routing policy,packets can be forwarded with no need to use a routing table:policy-based routing mainly controls the importing,advertising,and receiving of routing information so as to affect the forwarding of data packets.True FalseFalse137.The

that is directly connected with file server is configured as the root bridgeTrue FalseTrue142.IF loop exists and STP is not enabled,the switch will not operate normally True FalseTrue143.RSTP adopts fast convergence mechanism,So,there is no forward delay interval in RSTP True FalseFalse144.Two switches are directly connected to each other and they are working in full duplex mode.By default,RSTP will consider the link between the switches as point-to-point linkTrue FalseTrue145.In RSTP network environment,a port can be set as edge port when it is directly connected with terminalTrue FalseTrue146.In a switching network that runs RSTP,the topology change notification message will not be sent when the switch detects that the Alternate port is faile.True FalseTrue147.VLANs isolate

The first Board meeting of the current Board took place in late December and I am happy to report that Executives were returned to their previous roles. For the benefit of all members, I will list the current Board of Directors as well as our Senior Management Team. That will be posted on the company’s website. One thing, is worth your attention, well, we have a new HR Manager Hannah Eddy. I believe that she will enhance our administration in the following hard days. The coming year presents both ongoing and new challenges to the Management team on a number of fronts. These challenges include the continued implementation by the government of legislation directly affecting the day-to-day operations of the club. Obviously the introduction of plastic glasses appears not far from the horizon and yet again community clubs are being lumped into the same basket as night clubs operating until the early morning hours. The implementation of a new driver’s license(Smart Card)and the issues that this will raise in relation to their use as a form of identification will need addressing. The final recommendations of the Productivity Commission from its inquiry into gambling and what impact these have if they are adopted. As I have raised previously the results of the Productivity Commission are the most eagerly awaited as they have the potential to change the way the Club operates as well as our continued support of the community in general. Our courtesy bus service began operating in early December and has proven to be very popular with members. The implementation of this service has not been without complaint. The major complaint has related to the area the service covers. All complaints have been recorded and a review of the operation of this service is being undertaken to determine where and how to operate this service in the most efficient way, although any solution that is implemented will not be able to meet the needs of every member. Our General Manager Tony and his assistant Steve have purchased 37 additional Gaming Machine licenses from another club and in the coming weeks will see the addition of new and updated product to the gaming floor. Whilst we have received approval for an additional 60 machines, these will not all be installed immediately. It is hoped the additional machines will meet the need during our busier periods. “The happiest people don’t necessarily have the best of everything. They just make the best of everything.” Have a fantastic Easter everyone and we look forward to seeing you in the club.[pause]Now listen to the recording again.[pause]That is the end of Part One. You now have 20 seconds to check youranswers.[pause]You will hear a chairman delivering a report at an annual conference which will be allowed to read online. As you listen, for questions 1-12, complete the notes using up to three words or a number.
