Most city parks are places where you can escape from big, ugly structures of metal and stone. The Manhattan High Line is different. Raised 25 feet above the ground, this large metal structure once supported a rail line. The line opened in 1934 to bring trains directly into factories. It was hardly used after the 1960s, and much of it was torn down. However, one part remained in a region of Manhattan called Chelsea. Chelsea was becoming high-class as restaurants, art galleries and apartments were built, but the ugly railway structure remained as a dead weight. Everyone knew that at some time, it would have to be removed.
But the High Line was not destroyed. In fact, now the old rail line serves as one of the most peaceful places in the city. It holds an elevated park, with beautiful gardens and great views of the city. The idea to turn the rail line into a park came from Joshua David and Robert Hammond. In 1999, they attended a meeting to decide how to deal with the High Line. David and Hammond were the only people at the meeting interested in saving the historical structure. Later on, when they asked railway officials to take them up to look at the High Line, they saw a mile and a hall of wild flower growing in the middle of the city, and they realized that the High Line had potential to become a park. There was growing interest in improving city centers, and so the project quickly developed and money for construction was easily collected.
The first part of the High Line opened in 2009 and immediately became popular with tourists and locals alike. Each part of the park has a different atmosphere. Some areas are like balconies (阳台) with wonderful city views. Where the rail line goes between buildings, trees are thickly planted. Other sections have wide lawns (草坪) and walkways with wild flowers. Only the final section remains the way it has been for the last fifty years.
38．What is the text mainly about?
A．Closing a train line. B．An unlikely place for a park.
C．Protection of cultural relics. D．Improving city transport.
39．What does the underlined part “a dead weight” in paragraph 1 mean?
A．Something with historical interest.
B．Something with potential to be better.
C．Something useless which slows progress.
D．Something which is a danger to people.
40．Why did David and Hammond originally want to save the High Line?
A．They wanted to reopen the train line.
B．They thought it had historical value.
C．They were interested in improving the city.
D．They thought it would become a good park.
41．What can we learn about the High Line from the text?
A．Only part of the line remains.
B．The railway companies still use the line.
C．It began to become popular in the 1960.
D．It was designed by David and Hammond.

Unlike most U.S national parks, Everglades national park, located in south Florida, was created to protect a fragile ecosystem(生态系统)instead of safeguarding a unique geographic feature. It is a heaven for a wide range of wildlife, such as turtles, snakes, lizards, the Grass frog, Wading birds and so on, among which are fierce American alligators(鳄鱼). It is said that some of the alligators often appear in the areas where people live, causing much damage.
A terrible incident happened on a hot summer day. It was so hot a day that nearly every one felt like jumping into the cool water. A little boy simply couldn’t put up with the heat, deciding to go fora swim in the old swimming hole behind his house.
“Mum, it being so hot, I want to have a swim.” the boy told his mother while walking out.
“No, Honey, there has been a warning that an alligator from the park has appeared in the surrounding area. It is dangerous!” said his mother in a loud voice. But the little boy rushed out of the back door like a gust of wind before his mother could stop him.
He was in such a hurry to dive into the cool water that he left behind shoes, socks, and shirt as he left.
He flew into the water and enjoyed the comfortable feeling that the cool water brought him, not realizing that as he swam toward the middle of the lake, an alligator was swimming toward him. His mother was preparing dinner in the kitchen when suddenly she caught the two getting closer and closer to each other as she was looking out of the window. “Oh, My God!” she couldn’t help crying loudly, getting into a great panic. And then in great fear, she ran toward the water, shouting to her son as loudly as she could all the way, “Alligator, Alligator!”
Hearing her voice, the little boy became alarmed and made a U-turn to swim to his mother. However, it was too late. Something horrible was happening.
注意：1.续写词数应为150左右；
2.请按如下格式在在答题卡的相应位置作答。
Just as he approached her, the alligator reached him.

Part 3 读后续写
参考答案一：
Just as he approached her, the alligator reached him. From the shore, the mother grabbed her little boy tightly by the arms just as the alligator snatched his legs. It seemed as if it were an incredible tug-of-war between the two. The alligator was much stronger than the mother, but the mother was much too devoted to let go. Fortunately, a farmer happened to drive by. Hearing their screams, he raced from his truck, took aim and shot the alligator. Seriously wounded, the boy was rushed to the hospital.
Remarkably, after weeks in the hospital, the little boy survived. His legs were extremely scarred by the attack of the animal. And on his arms were deep scratches, where his mother’s fingernails dug into his flesh in her effort to hold onto the son she loved. When asked to show his scars, the boy lifted his legs and then with obvious pride, he said to people coming to see him, “But look at my arms. I have great scars on my arms, too. I have them because my mom wouldn’t let go.”
参考答案二：
Just as he approached her, the alligator reached him. Deeply shocked by the terrible scene, mother rushed to her son, catching hold of him tightly, with all her might. However, the alligator was much stronger than the mother. In spite of this, mother was so determined that she wouldn’t let go of her son, screaming for help at the same time. Hearing the frightening cry, a neighbor rushed out, with a gun in his hand, took aim and then shot the alligator. The boy got saved, but seriously injured.
Remarkably, after weeks in the hospital, the little boy survived. Seeing his mother and the neighbor sitting beside him, the boy hugged his mother, with tears in his eyes, feeling greatly regretful that he didn’t listen to her. Both of them expressed sincere gratitude to the neighbor. Without him, the son would have lost his life. And then the neighbor suggested putting up a warning sign at the side of the lake to inform others of the danger. The boy understood the significance of safety from then on.

1.段落续写：
①由第一段首句内容“Just as he approached her, the alligator reached him.(当他游近她的时候，鳄鱼已经靠近了他。)”可知，第一段可描写妈妈与鳄鱼在争夺小男孩之间的“拉扯”，一个出于母爱，一个出于“饥饿”，不相上下，最终有人帮助救下小男孩。
②由第二段首句内容“Remarkably, after weeks in the hospital, the little boy survived.(经过几周的住院治疗，小男孩竟然活了下来。)”可知，第二段可描写这次鳄鱼攻击对于小男孩留下的伤疤，以及他的感受。
2.续写线索：妈妈拉住小男孩——鳄鱼抓住小男孩的腿——妈妈和鳄鱼的拉锯战——有人帮助——小男孩获救送往医院——鳄鱼攻击后的伤疤——男孩对于妈妈极力救自己的感受
