Text 1 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. When did the Tower begin to lean

第三篇 Florida Hit by Cold Air Mass In January, 2003, the eastern two thirds of the United States was at the mercy of a bitterly cold air mass that has endangered Florida’s citrus trees, choked 3 northern harbors with ice and leftbewildered residents of North Carolina’s Outer Banks digging out of up to a foot of snow. The ice chill deepened as temperatures fell to the single digits in most of the South, with an unfamiliar dip below the freezing mark, as far South as parts of interior South Florida. Temperatures in Florida plunged, with West Palm Beach dropping to a record low of 2 degrees. "We couldn’t believe how cold it was," said Martin King, who arrived this week in Orlando from England "We brought shorts, T-shirt, and I had to go out and buy another coat." The temperature plunge posed a threat to Florida’s USS 9.1 billion-a-year citrus crop, more of which is still on the trees. Growers were hurrying to harvest as much of the fruit as possible before it was damaged by cold. "Time is of the essence in getting fruit to the plant," said Tom Rogers, a citrus grower who expected to see damage to oranges and grapefruit at that time. In Florida, Governor Jeb Bush signed an emergency order to eliminate the weight limit on trucks so citrus growers could get as much fruit to market as possible. Casey Pace, a spokeswoman for Florida Citrus Mutual, said growers had sprayed trees with sprinklers, which created a layer of ice and helped maintain a temperature near freezing. Citrus trees are considered in danger of damage if the temperature drops below minus 2 degrees Celsius for four hours or more. Snow ranging from a dusting to up to 30 centimeters blanketed the Carolinas, Tennessee and parts of Virginia. citrus n. 柠檬，柑橘；柑橘属果树 bewilder v. 使迷惑；使为难；……弄糊涂 sprinklern. 洒水器；洒水手 Celsius adj.摄氏的 shorts n. 宽松运动裤；男式短衬裤 Which of the following statements is not meant in the first two paragraphs
