Rising SeаsAs the plаnet wаrms, the sea rises, and cоastlines flооd, how will we face the danger of rising seas? Storm of the Century [A] By the time Hurricane Sandy veered toward the northeast coast of the United States on October 29, 2012, it had mauled 1 several countries in the Caribbean and left dozens dead. Faced with the largest storm the Atlantic had ever produced, New York and other cities ordered mandatory evacuations of low-lying areas, but not everyone complied. Those who chose to ride out Sandy got a preview of the future, in which a warmer world will lead to rising seas. [B] Brandon d'Leo, a sculptor and surfer, rented a second-floor apartment across the street from the beach on New York City's Rockaway Peninsula. At about 3:30 in the afternoon, he went outside. Waves were crashing against the nine-kilometer-long boardwalk. A short time later, d'Leo and a neighbor were watching the sea through the glass door of his living room when his neighbor saw something alarming. "I think the boardwalk just moved," she said. Within minutes, another surge of water lifted the boardwalk again, and it began to break apart. [C] Three large sections of the boardwalk smashed against two pine trees in front of d'Leo's apartment. The street had become a river 1.2 meters deep; cars began to float. After the storm, d'Leo said, "I have six surfboards in my apartment, and I was thinking, if anything comes through that wall, I'll try to get everyone on those boards and try to get up the block." [D] After a difficult night's sleep, d'Leo went outside and saw that the water had retreated, thigh-deep pools still filled parts of some streets. "Everything was covered with sand," he said. "It looked like another planet." 1 If someone is mauled (e.g., by a wild animal), they are attacked fiercely and aggressively. QUESTION:Who does the word "those" in the last sentence of paragraph A refer to? Be specific.
Dutch Lessоns [K] Cаn а single stоrm chаnge nоt just a city's but a nation's policy? It has happened before. The Netherlands experienced its own coastal catastrophe nearly 70 years ago, and it transformed the country. [L] The storm roared in from the North Sea on the night of January 31, 1953. Ria Geluk was six years old at the time and living on an island in the Dutch province of Zeeland. She remembers a neighbor knocking on her family's door in the middle of the night to tell them that the dike 3 had failed. Later that day, the whole family climbed to the roof. Geluk's grandparents lived just across the road, but water poured into the village with such force that they were trapped in their home, and they died when it collapsed. The disaster killed 1,836 in all, including a baby born on the night of the storm. [M] Afterwards the Dutch began an ambitious program of dike and barrier construction called the Delta Works, which lasted more than four decades and cost more than $6 billion. One crucial project was the eight-kilometer barrier built to defend Zeeland from the sea. The final component of the Delta Works - a movable barrier protecting Rotterdam Harbor and some 1.5 million people - was finished in 1997. Like other sea barriers in the Netherlands, it's built to withstand a 1-in-10,000-year storm - the strictest standard in the world. [N] The transparent domes of Rotterdam's Floating Pavilion represent an even more innovative approach to taming 4 the sea. The three domes - each about three stories tall - are made of a plastic that is a hundred times as light as glass. Though the domes are used for meetings and exhibitions, their main purpose is to demonstrate the potential of floating urban architecture. The city anticipates that as many as 1,200 homes will float in the harbor by 2040. "We think these structures will be important not just for Rotterdam but for many cities around the world," says Bart Roeffen, the architect who designed the pavilion. [O] An inscription 5 on the side of a storm-surge barrier in Zeeland says " Hier gaan over het tij, de maan, de wind, en wij" - Here the tide is ruled by the moon, the wind, and us. It reflects the confidence of a generation that took for granted - as we no longer can - a reasonably stable world. "We have to understand that we are not ruling the world," says Jan Mulder of Deltares, a Dutch coastal management firm. "We need to adapt." 3 A dike is a long wall that prevents water from flooding a place. 4 If you tame something dangerous, you bring it under control. 5 An inscription is writing carved into something made of stone or metal. QUESTION:Write in one sentence a central point (thesis) for the section, Dutch Lessons.
