Article: You may have heard the term "the American Dream". In 1848, James W. Marshall found gold in California and people began having golden dreams. That 19th century "American Dream" motivated the Gold Rush and gave California its nickname of the "Golden State". The American Dream drove not only 1800s gold-rush prospectors but also waves of immigrants throughout that century and the next. People from Europe, and a large number of Chinese, arrived in the US in the 19th century hoping that in America they would find gold in the streets. But most, instead, worked as railroad labourers. They created the oldest Chinatown, in San Francisco, and gave the city a Chinese name "the old gold hill". In the 20th century, some critics said that it was no longer possible to become prosperous through determination and hard work. Unfair education for students from poor families and racial discrimination almost made the American Dream a nightmare. Then, in the 1990s, California saw a new wave of dreamers in Silicon Valley. People poured their energy into the Internet. This new chapter of the American Dream attracted many business people and young talents from China and India to form start-ups and seek fortunes in America. Better pay, a nice house, and a rising standard of living will always be attractive. However, the new American Dream is no longer just about money. It encourages Americans to consume wisely to protect the environment, improve the quality of life, and promote social justice. The Governor of California, Arnold Schwarzenegger, has become the model of the new American Dream. After years of hard work, he grew from a poor young man from Austria into a movie superstar and then governor. Many people hope his story can save the American Dream and give California a brighter future. Question: It can be inferred that _ . Yes or no, is the answer "each period of time has its own taste of the American dream"?
(Answer)
No

Article: (2013*,B)On a sunny day last August,Tim heard some shouting.Looking out to the sea carefully,he saw a couple of kids in a rowboat were being pulled out to sea. Two 12yearold boys,Christian and Jack,rowed out a boat to search for a football.Once they'd rowed beyond the calm waters,a beach umbrella tied to the boat caught the wind and pulled the boat into open water.The pair panicked and tried to row back to shore.But they were no match for _ and the boat was out of control. Tim knew it would soon be swallowed by the waves. "Everything went quiet in my head,"Tim recalls ."I was trying to figure out how to swim to the boys in a straight line." Tim took off his clothes and jumped into the water.Every 500 yards or so,he raised his head to judge his progress."At one point,I considered turning back," he says."I wondered if I was putting my life at risk."After 30 minutes of struggling,he was close enough to yell to the boys,"Take down the umbrella!" Christian made much effort to take down the umbrella.Then Tim was able to catch up and climb aboard the boat.He took over rowing,but the waves were almost too strong for him. "Let's aim for the pier ,"Jack said.Tim turned the boat toward it.Soon afterward,waves crashed over the boat,and it began to sink."Can you guys swim?"he cried."A little bit,"the boys said. Once they were in the water,Tim decided it would be safer and faster for him to pull the boys toward the pier.Christian and Jack were wearing life jackets and floated on their backs.Tim swam toward land as water washed over the boys'faces. "Are we almost there?"they asked again and again."Yes,"Tim told them each time. After 30 minutes,they reached the pier. Question: Why did Tim raise his head regularly? Yes or no, is the answer "To check his distance from the boys."?

Article: The earth is not the only body that travels around the sun. With it are eight other planets, fellow members of the sun's family. Two of them, Mercury and Venus, are nearer while the other six, namely Mars, Jupiter, Saturn, Uranus, Neptune and Pluto, also in their given order from the sun, are farther from the sun than the earth is. The farther they are, the longer trips they make around the sun. People noticed long ago that these traveling bodies moved around in the sky in definite paths. It is a force called gravity that holds them in their paths. We know that every little bit of matter in the universe pulls upon every other bit of matter. The pull between two bodies is proportional to the product of their masses. Because the sun is so large the pull between the sun and the planets are thus great. If it were not for this pull, the planets would fly off into space. In the same way there exists a pull between the earth and the moon, which keeps the moon traveling in its orbit around our planet, the earth. Gravity holds you to its surface, and pulls back to it the ball which you throw into the air. Of course the ball also pulls on the larger earth but the earth is so much larger that the pull is not noticed. Now remember that large bodies exert a greater pull than smaller ones which contain less material. But each object in the universe, no matter how small, pulls on all other objects to some degree. Question: Which two planets make the longest trips around the sun among all the planets in the solar system? Yes or no, is the answer "Neptune and Pluto."?
(Answer)
No
