考题 Shoe Co, a shoe manufacturer, has developed a new product called the ‘Smart Shoe’ for children, which has a built-in tracking device. The shoes are expected to have a life cycle of two years, at which point Shoe Co hopes to introduce a new type of Smart Shoe with even more advanced technology. Shoe Co plans to use life cycle costing to work out the total production cost of the Smart Shoe and the total estimated profit for the two-year period.Shoe Co has spent $5·6m developing the Smart Shoe. The time spent on this development meant that the company missed out on the opportunity of earning an estimated $800,000 contribution from the sale of another product.The company has applied for and been granted a ten-year patent for the technology, although it must be renewed each year at a cost of $200,000. The costs of the patent application were $500,000, which included $20,000 for the salary costs of Shoe Co’s lawyer, who is a permanent employee of the company and was responsible for preparing the application.The following information is also available for the next two years:Shoe Co is still negotiating with marketing companies with regard to its advertising campaign, so is uncertain as to what the total marketing costs will be each year. However, the following information is available as regards the probabilities of the range of costs which are likely to be incurred:Required:Applying the principles of life cycle costing, calculate the total expected profit for Shoe Co for the two-year period.(10 marks)

考题 共用题干 第一篇U. S. Blacks Hard-hit by CancerDeath rates for cancer are falling for all Americans,but black Americans are still more likely to die of cancer than whites,the American Cancer Society said Monday.In a special report on cancer and blacks,the organization said blacks are usually diagnosed with cancer later than whites,and they are more likely to die of the disease.This could be because of unequal（不平等的）access to medical care, because blacks are more likely to have other diseases as well,and perhaps because of differences in the biology（生物学）of the cancer itself, the report added."In general,black Americans have less hope of surviving five years after diagnosis than whites for all cancer sites and all stages of diagnosis,"the report said,"In describing cancer statistics for black Americans,this report recognizes that many of the differences associated with race may be caused by unfair social and economic differences and unequal access to medical care."The cancer society said blacks should be encouraged to get check-ups（体格检查） earlier,when cancer is more treatable,and it said more research is needed to see if biological differences play a role."The new statistics emphasize the continuing importance of wiping out these unfair social differences through public policy and education efforts,"the organization said in a statement.But it also noted a drop in cancer death rates."Cancer death rates in both sexes for all sites combined have dropped greatly among black Americans since 1992,as have incidence rates（发生率）,"said the report. Black Americans are more likely to die of cancer thanA:people in other countries. B:white Americans.C:all other Americans. D:their ancestors.

考题 共用题干 第三篇Infection of AIDSAccording to a report of the World Health Organization,this year will see 2.6 million deaths from AIDS,the highest yearly international total since the disease began to take hold in the late 1970s, despite questionable antiretro-viral drugs（抗逆转录酶病毒药）that staved off AIDS deaths in the richer countries.As things stood,the number of deaths was likely to increase for many years before peaking. The report said about half of all people who acquired HIV become infected before they turned 25 and usually died before their 35th birthdays of AIDS,which destroys the body's immune methods.Although ninety-five percent of people with HIV live in the developing world,battling HIV rates was still a challenge in the developed countries of the West,where there are"very worrying facts" that safe sex practices are dropping among gays.While AIDS deaths in the United States dropped by 42 percent between 1996 and 1997,the figure dropped by only half that between 1997 and last year.The report added that in Eastern Europe and Central Asia,the number of infected people had risen by a third this year,to 360,000.This was mainly due to an increase in the use of infected needles to inject drugs in Russia and the Ukraine. More than 2,700 cases of HIV were reported in Moscow in the fitst nine months of this year.Although cases of HIV remain relatively low in the Middle East,increasing use of injected drugs accounted for two thirds of new HIV cases in Bahrian last year,half in Iran and more than a third in Tunisia.According to the passage above,which of the following statements is not true?A:The number of people infected with HIV is increasing.B:Some new drugs can help delay AIDS deaths in countries where AIDS cases are found.C:There are more people who died of AIDS worldwide this year than any other year in the past.D:Most people with HIV live in the developing world.

The introduction of the NHS（国民保健制度）breast screening program has also contributed as the earlier cancer is diagnosed,women are more likely to survive."Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease一a 50% rise in 25 years.The number of deaths peaked in 1989,when 15,625 women died.It then fell by between 200 and 400 deaths each year until 2004.There was a slight rise in 2005 and then two years of falls.Dr. Sarah Cant,policy manager at Breakthrough Breast Cancer,said,"It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments,breast screening and awareness of the disease.""However,there are still too many women affected and the incidence of the disease is increasing year byyear.,,The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity （肥胖）and alcohol consumption.The rate of breast cancer diagnosis in the UK has been dropping.A:RightB:WrongC:Not mentioned

考题 共用题干 第二篇Need for Emphasis on TreatmentAIDS programs in developing countries put too little emphasis on treatment,the World Health Organization said Tuesday,asking for more small community-based clinics to be opened to treat HIV-infected people.An estimated 36 million to 46 million people are living with AIDS,two-thirds of them in Africa,but only 440,000 people in developing countries were receiving treatment by the end of 2003,the UN health agency said in its annual report."Without treatment,all of them will die a premature and in most cases painful death,"the WHO said in the 169-page World Health Report.WHO Director General Lee Jong-wook said community-based treatment should be added to disease pre- vention and care for sufferers in AIDS programs."Future generations will judge our time in large part by our response to the AIDS disease,"Lee said. "By tackling it decisively we will also be building health systems that can meet the health needs oftoday and tomorrow. This is a historic opportunity we cannot afford to miss,"he added.Antiretroviral drugs enable people hit by AIDS to live longer. The annual cost of treatment,which was about $10,000 when the drugs were first developed,has dropped to about$150.Treatment programs also help AIDS prevention efforts,the report said,citing great demands for testing and counseling where treatment has been made available.Good counseling in turn leads to more effective prevention in those who are uninfected,and significantly reduces the potential for HIV carriers to pass on the infection,the report said.Since its discovery in the 1980s,more than 20 million have died of AIDS,mostly in poor countries.How many people have died of AIDS so far?A:36 million.B:46 million.C:Around 440, 000.D:More than 20 million.
