At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the likelihood of death is least. Earlier, we were infants and young children, and consequently more vulnerable; later, we shall undergo a progressive loss of our vigor and resistance which, though imperceptible at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigor with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and disease we shall eventually "die of old age", and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer—on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and robust we are. Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigor with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do, if given the chance to live long enough; and mechanical systems like a wound watch, or the sun, do in fact run out of energy in accordance with the second law of thermodynamics (热力学) (whether the whole universe does so is a moot point at present). But these are not analogous to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself—it does not consist of living parts, only of metal, which wears away by friction. We could, at one time, repair ourselves—well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power; an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again. Which of the following statements is INCORRECT
A. Our first twelve years represent the peak of human development.
B. People usually are unhappy when reminded of ageing.
C. Normally only a few of us can live to the eighties and nineties.
D. People are usually less likely to die at twelve years ol

Imagine you are a citizen of Athens, enjoying a warm Mediterranean night in the Theater of Herodes Atticus. You are wearing jeans and a T-shirt, listening to a great concert. Now rewind this picture 1,839 years. You are in the same seat, only you are watching classical Greek entertainment and wearing a simple chiton, or tunic. The city of Athens is a fun mix of the old and the new, the classic and the modem. Often a little shop is located next to the ruins of a temple, which is only a block from a large, air-conditioned hotel. The great city of 2,500 years ago is still visible today. Ruins are the most obvious sign of ancient Athens, and the most famous of these is the Acropolis. The Acropolis is a large hill that was the center of life in Athens. On its slopes were temples, monuments, and theaters. From the top, you can see how the urban sprawl (扩展,延伸) of Athens stretches out in every direction. On the top of the Acropolis is the Parthenon. This was once a huge temple to Athena, the city’s patron. It was first completed in 432 B.C., but has been damaged and destroyed several times. However, visitors can still see the "tricks" used in building the Parthenon. The columns along the outside lean inward, and are slightly fatter in the middle. The temple is also higher in the middle than on the sides. All these effects make the Parthenon look perfectly straight from a distance. Only a block away from the Acropolis is the neighborhood of Plaka. The area, with its little shops and restaurants, is very popular with both tourists and locals, and is an important part of modem Athenian culture. Many great thinkers, writers, and political leaders lived in ancient Athens. The ruins of their homes and favorite spots are scattered throughout the busy port city. The hill where St. Paul addressed early Christian Athenians is located near the Acropolis. Great thinkers such as Perikles and Demosthenes spoke to the civil assemblies held at the Pnyx Hill. Today the Pnyx is an open-air theater for light and sound shows. Greeks still use some ancient sites, such as the Pnyx and the Theater of Herodes Atticus. During Roman times, in 76 A.D., gladiators (角斗士) used the Panathenaic Stadium for contests. The Olympics were held there in 1896, and today people still jog and exercise in the stadium. Tourism is very important to people who live in modem-day Athens. Thousands of people come every year to see these ruins and to tour the many museums that house artifacts from ancient times. This provides many jobs and brings money into Athens, which helps the city pay for improvements. Athenians take pride in the accomplishments of their ancestors, and people from all around the world come to admire them. By looking around the city today, we can imagine what life was like in ancient Athens. What is the best title for the passage
A. Tourism in Athens.
B. Athens: Then & Now.
C. Historic Interests in Athens.
D. The Magic of Ancient Athens.
