D
A mysterious machine found in a 2,000-year-old Greek shipwreck may have been used to calculate the positions of planets, predict when eclipses (日、月蝕) were to occur, and study other parts of astronomy (天文學). When it was found underwater about 100 years ago, the machine was in poor shape. Its metal pieces had become one mass (堆), and then broke into pieces.
When the researchers began to study what was left of the machine, they thought it might have something to do with astronomy. To find out more, they recently used advanced imaging methods, including X-ray computer tomography (斷層攝影術(shù)), to look inside the metal parts and to check for ancient writing on the machine.
According to their research, the researchers believed that this machine could have been used to compute eclipses of the sun and moon and was also able to show the movements of planets. A user could pick a day in the future and, work out a planet’s position on that date by moving some sort of crank (曲柄) on the machine.
Besides, the researchers discovered that the machine had at least 30 bronze gears (齒輪) with as many as 225 teeth, likely all cut by hand.
With all the collected information, the researchers came up with a new model for how the machine operated. The model has 29 of the 30 known gears and five more that were probably there but never found. Also，the new picture adds a previously undiscovered spiral dial (螺旋刻度盤) to the back of the machine near the bottom. A hand moving around the dial could have pointed to eclipses over a period of 18 years.
71. The passage is most probably taken from _____.
A. a short-story collection
B. a popular science magazine
C. a political report
D. an old personal diary
72. What is the passage mainly about?
A. New research on calculating the positions of planets.
B. A popular way of computing eclipses of the sun and moon.
C. Scientists’ interest in the secrets of a 2,000-year-old Greek shipwreck.
D. A mysterious machine which could be used for astronomical research.
73. What do we learn from the third paragraph of the passage?
A. The machine might have been used to calculate the positions of the planets.
B. Scientists made great progress in predicting eclipses of the sun and moon.
C. The researchers discovered some secrets in the Greek shipwreck.
D. The machine can be of great help for people working out the sizes of planets.
74. The researchers made a new model because they____.
A. wished to repair the broken machine
B. wanted to study the shipwreck more conveniently
C. hoped to know how the machine worked
D. expected it to be used in modern scientific research
75. Which of the following statements is TRUE about the old machine?
A. It has 35 gears on it.
B. It has a spiral dial.
C. It was invented about 100 years ago.
D. Its gears have many teeth.

科目：高中英語 來源：2012年新課標版高中英語選修七 Unit1練習卷（解析版） 題型：閱讀理解

The concept of health holds different meanings for different people and groups. These meanings have also changed over time. This change is no more evident than in Western society today, when notions of health and health promotion are being challenged and expanded in new ways.

For much of recent Western history, health has been viewed in the physical sense only. That is, good health has been connected to the smooth mechanical operation of the body, while ill health has been attributed to a breakdown in this machine. Health in this sense has been defined as the absence of disease or illness and is seen in medical terms.

In the late 1940s the World Health Organization challenged this physically and medically oriented (導向的) view of health. They stated that health is a complete state of physical, mental and social well-being and is not merely the absence of disease (WHO, 1946). Health and the person were seen more holistically (mind / body / spirit) and not just in physical terms.

The 1970s was a time of focusing on the prevention of disease and illness by emphasizing the importance of the lifestyle and behaviour of the individual. Specific behaviours which were seen to increase risk of disease, such as smoking, lack of fitness and unhealthy eating habits, were targeted. Creating health meant providing not only medical health care, but also health promotion programs and policies which would help people maintain healthy behaviours and lifestyles. While this individualistic healthy lifestyle approach to health worked for some (the wealthy members of society), it was of little benefit to people experiencing poverty, unemployment, underemployment or who had little control over the conditions of their daily life.

During the 1980s and 1990s there has been a growing swing away from seeing lifestyle risks as the root cause of poor health. While lifestyle factors still remain important, health is being viewed also in terms of the social, economic and environmental contexts in which people live. This broad approach to health is called the socio-ecological view of health.

At the Ottawa Conference in 1986, a charter was developed which outlined new directions for health promotion based on the socio-ecological view of health. This charter, known as the Ottawa Charter for Health Promotion, remains as the backbone of health action today. In exploring the scope of health promotion it states that:

Good health is a major resource for social, economic and personal development and an important dimension (尺度) of the quality of life. Political, economic, social, cultural, environmental, behavioural and biological factors can all favour health or be harmful to it. (WHO, 1986)
