单选题Pisa is an Italian city known for its Leaning Tower. The Tower, interestingly enough, started leaning in the middle of its construction — when its first three stories were completed. Bonnano Pisano, the engineer in charge, tried to correct the lean by making the new stories slightly taller on the short side, only to find that the added marble caused the Tower to sink still further. Work was suspended several times as engineers sought fresh solutions, until the Tower was finished in the 14th century, still leaning. The construction, begun in 1174, nearly took 200 years. In modern times the structure has been several times strengthened by cement, but to this day it is still in danger of collapse. Various schemes have been under consideration for saving, it. To rebuild an upright tower would be easy enough for modern engineering, but it would not be the same edifice as people love and remember it. The Leaning Tower must be left leaning, saved, not reconstructed. There is nothing really wrong with a leaning tower — after all, Galileo climbed to the top and did his experiment by throwing down weights. In the meantime, the Tower has been closed to the public since 1990.

单选题Culture (文化) unchangingly molds (影响) human biology. Culture encourages certain activities, discourages others, and sets standards of physical health and attractiveness (吸引力). Sports activity, which is influenced by culture, helps build phenotype (具有共同类型的一类有机物). American girls are encouraged to pursue and so, they do well in -competitive track and field, swimming, and diving. Brazilian girls are encouraged to avoid public activities. In Brazil fewer females swim, drive, and run than is the case in America. Culture standards of attractiveness also affect athletic activities. Americans run or swim not just to compete but to keep trim (漂亮的) and fit (健康的). Brazil' s beauty standards accept more fat, especially in female buttocks and hips. Years of swimming mold an enlarged upper torso, a massive neck, and powerful shoulders and back. Successful women swimmers tend to be big, strong, hard and bulky, but Brazilian culture says that women should be soft. A Brazilian beauty should have big hips and buttocks rather than big shoulders. So Brazil seldom sends female swimmers or runners to the Olympics. The countries that produce successful female swimmers are the United States, Germany, and Russia or any other one but not Latin countries including Brazil.

单选题Kite flying is the sport of sending up kites into the air, by means of the wind, a light frame covered with paper, plastic or cloth. The frame can be one of many different shapes and is attached to a long string held in the hand or wound on a drum. Kites have a long history of practical application and many different types of kites have been developed to serve various purposes. The ancient Chinese used bird-kites to carry ropes across rivers and valleys. The current folding kite which will dive excitingly is an improved type of such a kite. With its long flat body and single pair of bird-like wings, it looks just like a large bird in the air. The modern version is usually made of tissue-paper rather than the traditional silk. Man-lifting kites were developed in ancient times, again by the Chinese, for getting information from walled cities and army camps. In fact, as recently as World War Ⅱ , German U-boats flew kites from their towers to lift people into the air to watch the land. These kites, which are no longer in existence, were made of light-weight cloth. They were much larger and stronger than the Chinese ones. Their design, however, was simply that of the cutter kite. Smaller in size, this type of kite is still very popular as a toy for children, being easy to make with a diamond-shaped frame, no wings and brown-paper covering. Box-kites are another type of kite found in toy shops today. The first box-kite, named for its box-like body, was developed in the nineteenth century to test theories of flight and this type of cotton-covered kite greatly assisted the success of early aero-plane. These kites are the ancestors of a heavier version of the box-kite, which consists of two main sections, placed side by side. Developed for the peacetime purpose of fishing in strong sea wind, it is the only modern kite described which has practical value. A long-lasting plastic material has to be used for this kite, which carries fishing lines.
