What can be concluded from the passage
A．Medical tests and education for Americans with diabetes are not covered by the present healthcare schemes.
B．If you are 20 years old or more, you are more likely to suffer from diabetes.
C．Family help is the more important and most effective in detecting and treating diabetes.

参考答案：A
解析：[听力原文]Today, I’m pleased to announce that starting on July 1 for the very first time, medicare will cover tests and education for Americans with diabetes. With this announcement today, the 20 percent of older Americans with diabetes will be able to take preventive steps to help them and their families avoid the pain and loss that can come when this disease is undetected and untreated.
[分析]： 推理判断题。 根据原文第一句... that starting July 1 for the very first time，medicare will cover tests and education for Americans with diabetes 可知，从七月一日起，美国糖尿病患者的测试和教育均纳入医疗保健制度。由此可推断，该日以前，美国医疗保健制度是不包括糖尿病患者的测试和教育的。因此A项内容与原文意思相符，因此是正确答案。[解题关键] 根据题干关键词正确找到原文相关信息，并做简单推断。
