尼古拉·特斯拉:工业革命的领航人
作者: 孙启禄1 Nikola Tesla holds his hat in his hand. He points his walking stick towards Niagara Falls and signals bystanders to turn their gaze to the future. This bronze Tesla—a statue on the Canadian side—stands at the top of an induction motor, the type of engine that drove the first hydroelectric power plant.
2 We owe much of our modern electrified life to the lab experiments of the Serbian⁃American engineer born in 1856 in whats now Croatia. His designs advanced alternating current at the start of the electric age and allowed companies to send current over vast distances, powering American homes across the country. He developed the Tesla coil—a high⁃voltage transformer (高压变压器)—and techniques to send power wirelessly. Cellphone makers (and others) are just now using the potential of this idea.
3 Tesla is perhaps best known for his extraordinary genius. He once proposed a system of towers that he believed could pull energy from the environment and send signals and electricity around the world, wirelessly. But his theories were unsound, and the project was never completed. He also claimed he had invented a “death ray”.
4 In recent years, Teslas mystery has begun to make his inventions seem less important. San Diego Comic⁃Con International attendees dress in Tesla costumes. The worlds most famous electric car bears his name. The American Physical Society even has a Tesla comic book where, as in real life, he faces off against Thomas Edison.
5 While he was really a genius, much of his reputation was of his own making. Tesla claimed to have accidentally caused an earthquake in New York City using a small steam⁃powered electric generator hed invented—Myth Busters showed the falseness of that idea. And Tesla didnt actually discover alternating current, as everyone thought. It was around for decades. But his theories, inventions and patents made Tesla a household name, rare for scientists a century ago. And even today, his legacy still turns the lights on.

通常在一篇完整的文章中,作者会围绕某个特定的主题展开写作,并在篇首或篇中埋下相应的伏笔,在篇尾再进行符合逻辑且合理的照应,我们把这样的伏笔称为续写点。由此可见,续写点往往出现在续写原文中,如果我们能深入解读原文,挖掘合理的续写点,并在续写过程中进行照应,那么我们所续写出来的段落无论在语言、内容,还是逻辑上都能更加符合原文的基调,更能让阅卷老师眼前一亮。
【案例导引】
Almost all the possessions had been sold to buy food and clothing for the family. At last, nothing was left but the pet lamb, Daisy. At the thought of parting with the little creature, Mrs Grant felt sad because the children loved it very much. Having struggled hard, she had to make up her mind to sell the lamb. But she could not ask any child to go for the butcher. Finally, she went herself with a heavy heart and bargained with the butcher for the sale of Daisy.
While the children were all playing with the lamb, the butcher and his boy came to the door. “You see, I am here for the lamb,” said the butcher in a loud voice. Hearing this, one child ran to her mothers side, and asked what was happening in alarm. Mrs Grant gently pushed the child aside, bent down and was about to tell the truth.
“Thats my lamb now, Charlie!” said the butchers boy in a playful tone, going up to Daisy with a rope in his hand.
“No, it is not your lamb. It is ours!” said Charlie, placing himself in front of it.
But the boy, pushing him aside, threw a rope round Daisys neck, and began to drag the little creature away. The poor lamb bleated (咩咩叫) very sadly. The cry of grief which fell upon the mothers ears was too much for her, and her heart sank inside her. In a moment, begging with tearful eyes, the children were all around their mother with voices choking with sobs for their little pet.
“Please tell your boy to stop for a moment,” she said in husky (深沉沙哑的) tones to the butcher. The boy, at a word from the butcher, stopped dragging the lamb, and the little creature stopped bleating.
In a trembling voice, Mrs Grant explained to children how badly off they were after their father died. She also added that the kind butcher had given the money for Daisy. With this money, she could buy her children bread to eat.
