8、lanet, or new plans to battle its effects. But the concept itself isnt new at all in fact, scientists have been exploring questions about climate change for almost 200 years.The idea of “greenhouse gases” goes back to 1824, when Joseph Fourier wondered what was regulating the earths temperature. Fou
9、rier concluded that the atmosphere must be responsible for containing the heat absorbed from the sun and described it as a box with a glass lid: As light shines through the glass, the inside gets warmer as the lid traps the heat. As Fouriers ideas spread, it came to be called “the greenhouse effect”
10、.Scientists continued to study the greenhouse effect. Not until a Swedish chemist named Svante Arrhenius came along, did scientists understand how global warming actually works. After years of work, Arrhenius determined that the level of carbon dioxide in the atmosphere did in fact have a direct eff
11、ect on global temperatures.Arrhenius found that CO2, and other gases trap radiation, which warms the atmosphere. Arrhenius was the first to suspect that burning coal could contribute to the greenhouse effect. But Arrhenius welcomed the warming effect on the planet. At a lecture later that year, Arrh
12、enius noted that creatures of a warmer earth “might live under a milder sky and in less barren surroundings”.While Arrhenius findings won him the 1903 Nobel Prize in chemistry, scientists kept debating whether the greenhouse effect was increasing until 1950, when researchers finally began to find st
13、rong data supporting it. By the end of the 1950s, American scientists had been sounding the alarm on the long-term consequences of climate change. Climate change research has come a long way since Fourier first described the greenhouse effect still, maybe Arrhenius should have been more careful of w
14、hat he wished for.4. What does the underlined word “it” in Paragraph 2 refer to? A. The climate change. B. The greenhouse effect. C. The atmosphere. D. The heat from the sun.5. When did the scientists first find evidence for the bad effect of global warming? A. In 1824. B. In 1903. C. In 1950. D. 20
15、0 years ago.6. Whats the authors attitude towards Arrhenius wish? A. Optimistic. B. Negative. C. Neutral. D. Ambiguous.7. Whats the main idea of the text? A. Causes of climate change. B. Effects of greenhouse gases. C. Findings about global warming. D. Explorations on climate change.C Its common kno
16、wledge that the woman in Leonardo da Vincis most famous painting seems to look back at observers, following them with her eyes no matter where they stand in the room. But this common knowledge turns out wrong.A new study finds that the woman in the painting is actually looking out at an angle thats
17、15.4 degrees off to the observers rightwell outside of the range that people normally believe when they think someone is looking right at them. In other words, said the study author, Horstmann, “Shes not looking at you.” This is somewhat ironic, because the entire phenomenon of a persons gaze （凝视） i
18、n a photograph or painting seeming to follow the viewer is called the “Mona Lisa effect” . That effect is absolutely real, Horstmann said. If a person is illustrated or photographed looking straight ahead, even people viewing the portrait from an angle will feel they are being looked at. As long as
19、the angle of the persons gaze is no more than about 5 degrees off to either side, the Mona Lisa effect occurs.Horstmann and his co-author were studying this effect for its application in the creation of artificial-intelligence avatars（虚拟头像） when Horstmann took a long look at the “Mona Lisa” and real
20、ized she wasnt looking at him. To make sure it wasnt just him, the researchers asked 24 people to view images of the “Mona Lisa” on a computer screen.So why do people repeat the belief that her eyes seem to follow the viewer? Horstmann isnt sure. Its possible, he said, that people have the desire to
21、 be looked at, so they think the woman is looking straight at them. Or maybe the people who first coined the term “Mona Lisa effect” just thought it was a cool name.8. What is generally believed about the woman in the painting “Mona Lisa”? A. She attracts the viewers to look back. B. She seems myste
22、rious because of her eyes. C. She fixes her eyes on the back of the viewers. D. She looks at the viewers wherever they stand.9.What gaze range in a painting will cause the Mona Lisa effect? A. B. C. D. 10 . Why was the experiment involving 24 people conducted? A. To confirm Horstmanns belief. B. To
23、create artificial-intelligence avatars. C. To calculate the angle of Mona Lisas gaze. D. To explain how the Mona Lisa effect can be applied.11.What can we learn from the text? A. Horstmann thinks its cool to coin the term “Mona Lisa effect”. B. The Mona Lisa effect contributes to the creation of art
24、ificial intelligence. C. Feeling being gazed at by Mona Lisa may be caused by the desire for attention. D. The position of the ruler in the experiment will influence the viewers judgment.DSparrow is a fast-food chain with 200 restaurants. Some years ago, the group to which Sparrow belonged was taken
25、 over by another company. Although Sparrow showed no sign of declining, the chain was generally in an unhealthy state. With more and more fast-food concepts reaching the market, the Sparrow menu had to struggle for attention. And to make matters worse, its new owner had no plans to give it the funds
26、 it required. Sparrow failed to grow for another two years. Until a new CEO, Carl Pearson, decided to build up its market share. He did a survey, which showed that consumers who already used Sparrow restaurants were extremely positive about the chain, while customers of other fast-food chains were u
27、nwilling to turn away from them. Sparrow had to develop a new promotional campaign. Pearson faced a battle over the future of the Sparrow brand. The chains owner now favored rebranding Sparrow as Marcys restaurants. Pearson resisted, arguing for an advertising campaign designed to convince customers
28、 that visits to Sparrow restaurants were fun. Such an attempt to establish a positive relationship between a company and the general public was unusual for that time. Pearson strongly believed that numbers were the key to success, rather than customers spending power. Finally, the owner accepted his
29、 idea. The campaign itself changed the traditional advertising style of the fast-food industry. The TV ads of Sparrow focused on entertainment and featured original songs performed by a variety of stars. Instead of showing the superiority of a specific product, the intention was to put Sparrow in th
30、e hearts of potential customers. Pearson also made other decisions which he believed would contribute to the new Sparrow image. For example, he offered to lower the rent of any restaurants which achieved a certain increase in their turnover （营业额） .These efforts paid off, and Sparrow soon became one
31、of the most successful fast-food chains in the regions where it operated. 12. Which was one of the problems Sparrow faced before Pearson became CEO? A. The number of its customers was declining. B. Its customers found the food unhealthy. C. It was in need of financial support. D. Most of its restaurants were closed. 13. For what purpose did Pearson start the advertising campaign? A. To build a good relationship with the public. B. To stress the unusual tradition of Sparrow. C. To learn about custome
