某机床厂按照目标管理的原则，把目标管理分为三个阶段进行，其中第一个阶段是目标制订阶段。下面是目标制订的过程。一、总目标的制订该厂通过对国内外机床市场需求的调查，结合长远规划，并根据企业的具体生产能力，提出了2009年“三提高”、“三突破”的总方针。所谓“三提高”，就是提高经济效益、提高管理水平和提高竞争能力;“三突破”是指在新产品数目、创汇和增收节支方面要有较大的突破。二、部门目标的制订企业总目标由厂长向全厂宣布后，全厂就对总目标进行层层分解，层层落实到各个部门。各部门的分目标由各部门和厂企业管理委员会共同商定。三、目标的进一步分解和落实部门的分目标确定以后，接下来的工作就是将目标进一步分解并层层落实到每个人。部门内部小组(个人)目标管理，其形式和要求与部门目标制订相类似，拟定目标也采用目标卡片，由部门自行负责实施和考核。要求各个小组(个人)努力完成各自的目标值，以保证部门目标的如期完成。该厂部门分解目标的具体方法是：先把部门目标分解落实到职能组，任务级再分解落实到工段，工段再下达给个人。通过层层分解，全厂的总目标就落实到了每一个人身上。根据以上案例，回答以下各题。1、该机床厂采用()的方法将任务分解到个人。

阅读下面短文，并按照题目要求用英语问答下列各问题（请注意问题后词数要求）。 A nurse of 78 this weekend celebrates 60 years of walking the wards - and she has no plans to retire. Jackie Reid was 18 when she started work in 1953 - when the National Health Service(NHS) was just five years old - and is believed to be the oldest nurse in Britain. The diabetes(糖尿病) specialist had to retire at 65 but returned as a nurse within two weeks and still does up to four seven-and-a-half hour shifts(轮班）each week. Mrs Reid said: 'Nursing is hard if you do it correctly but I love my job. Working for the NHS has been my life. I have no other hobbies because I have worked all my life. Jackie has worked at a number of different hospitals--including one in Scotland. Her specialist field has been diabetes for the past 40 years. She relrained after her 12-year-old daughter Michelle developed the disease. She currently works at Southend Hospital, Essex. Over the last 60years she has treated tens of thousands of patients. Jackie believes nursing should be protected from government cuts. She said: 'Therere lots of things I would say to the government. If you are going to get good care you have to have the resources(资源), you cant do it without enough money. They shouldnt need the cuts that there are in the NHS. Its hard now because theres a shortage of staff.' Jackie has lived alone in Grays, Essex, since her husband did three years ago. The couple have two daughters Michelle, 50, and Karen, 54. Jackie added: 'My youngest daughter worried about me - she doesnt think I should work as much as I do. I constantly say dont worry about me, Im fine, but she never believes me. I dont like the thought of giving it up and will try to keep going forever.' In which year was the NHS set up? (within 2 words)
