单项选择题 根据下列文章,请回答 23～30 题。 Health Promotion 1 World health will improve only if the people themselves become involved” in planning，implementing，and having a say about their own health and health care．But．1nvolvement．will not just happen．2 How serious are we about involving individuals，families，and communities? Are we prepared—mentally and professionally(专业上)-to Listen to their concerns，to learn from them what they feel 5is important，to share with them appropriate information，to encourage and support them? In many cases, SO far, the answer is‘N0’．We can go on and on developing plans：nothing will happen unless all health workers，all heath managers．and key professionals(专业人员)in other areas come to realize what is at stake．To overcome these particular stumbling-blocks(障碍物)。I see three major requirements．3 First health workers must understand that the concept of primary health care involves new roles for them，and a new outlook(观点)．Not only should we be concerned with disease prevention and control。we must also be concerned with health promotion and care，and not least with development in general—and with people．Our health technologies must be based on what the people themselves want and need．4 Second，health workers must accept their new roles。More yet：they must be keen to try them out．to broaden their scope and to innovate(创新)in the partnership(合伙人，合作关系)approach．Their main concern must be to find ways of helping individuals and communities become self-dependent．5 This brings me to my third point：health workers must have the necessary skills to perform. these new roles effectively and to make efficient use of existing knowledge．This calls for a training force fully familiar with previous experience and keen to provide the kind and quality of professional preparation needed．It also calls for full support from health manage for such training． 第 23 题 Paragraphs 2_____________A．Acceptance of New RolesB．Lack of Health TechnologiesC．Urgent Need to Improve the Current SituationD．Importance of Taking a New OutlookE．Support of the PeopleF．Demand for Necessary Skills
