提示：[1]D.细节题。本题问“这个年轻女性是如何到达广场的？”浏览文章后，我们并没有找到相关内容，所以答案是D（文章没有告诉我们）。
[2]C.细节题。本题问“为何这名女士要拦住那辆出租车？”答案在第三段，该段告诉我们这名女士想搭乘出租车到广场附近的一个饭店。据此可知答案是C。
[3]A.推断题。本题问“广场另一边的那个男青年______。”答案在最后一段，该段大意是“女士说道：‘哦，不是的。我本来答应在中午1点钟的时候和那个男士一起吃午餐的，但是现在已经是1点45分了。如果我乘坐出租车赶到那里的话，这至少显得我在尽力避免迟到。’”据此可以推测答案是A（很可能等待很长时间了）。
[4]A.推断题。本题问“这名女青年_______。”先浏览选项。A的意思“很善于编造理由”，B的意思“根本没有迟到”，C的意思是“早到了45分钟”，D的意思是“迟到了15分钟”。本题答案明显是A。
[5]B.推断题。本题问“这名女青年又没有尽力不迟到？”根据第三题的解释，我们可知这名女青年只是在假装避免迟到，所以答案是B。

1. People have been talking about health for a long time because people know the importance of it. People's understanding of health also becomes deeper with the progress in scientific research. Recently the term "health" has come to have a wider meaning than it used to. It no longer means just the absence of illness. Today, health means the well-being of your body, your mind and your relationship with other people. This new concept of health is closely related to another term----quality of life. Quality of life is the degree of overall satisfaction that a person gets from life. Why has the emphasis of health shifted from the absence of disease to a broader focus on the quality of a person's life？One reason for this has to do with the length and conditions of life that people can now expect. Medical advances have made it possible for people today to live longer, healthier lives. Imagine for a moment that you were born in the year 1900. You could have expected on average to live until about the age of 47. In contrast, if you were born in the year 1999, you could expect to live to the age of 75. 2. 1. ______leads to people's deeper understanding of health. 2. https://www.doczj.com/doc/2316195389.html,mon knowledge 2.Progress in scientific research 3.Better conditions of living 4.Quality of life 3. According to the passage, to people of today, health means______. 4. 1.absence of illness 2. a long life 3.good conditions of living 4.overall satisfaction with life
