When you watch your favorite movies, you might not think about science. Of course, there’s a lot of science behind movies like Interstellar or The Martian but not movies like Frozen or The Avengers, right? Think again.
Animated (動畫的) movies use a lot of science and math to make things look as real as possible. For example, snow was used in many parts of the movie Frozen, but making the snow look real was a challenge. The snow needed to act differently in different situations, like if it was melting (融化) or blowing (吹) in the wind.
Mathematicians (數學家) had to create a computer program to make the snow look more natural. Joseph Teran, a mathematician at the University of California, US, faced this challenge with Frozen, according to the Society for Science and the Public.
He and his team used math equations (等式) to treat snow like many different pieces instead of one large thing, as movies had done in the past. They worked for months to make a computer program do this.
Science is important for superhero movies too. Superheroes are supposed to have special powers that can’t always be explained. But moviemakers still want to make their actions realistic.
For example, Raychelle Burks, a chemistry professor (化學教授) from the American Chemical Society, told the Daily Mail that some of the science behind The Avengers could be real. Iron Man’s suit (服裝) is possible because it can be made of a light but strong material. In the movie, Tony Stark also makes new elements by making atoms collide (使原子對撞), much like scientists do in real life.
So next time you see a movie, don’t forget to think about the science behind it.
Choose the answer:
1. A lot of science and math are used in animated movies to _____.
A. make them like Interstellar and The Martian
B. make the audience think about science
C. make things as realistic as possible
D. make snow melt or blow in the wind
2. How did people make the snow in Frozen look more natural?
A. They had to create a new kind of computer.
B. They solved this problem with frozen technology.
C. They created some new math equations.
D. They used math knowledge to make a program.
3. The example of The Avengers in Paragraph 6 is used to show _____.
A. how superheroes have super powers
B. how science makes action realistic
C. Iron Man’s suit is made of light materials
D. how Tony Stark makes new elements
4. What can we learn from the passage?
A. Every movie should be made to look as realistic as possible.
B. Science and math play important roles in movie making.
C. Animated movies use less science than other movies.
D. Scientists can make things in movies become real.

What is your impression (印象) of Denmark? Many of you may know it as a country of fairy tales (童話) because it is the home place of Heinz Christian Andersen. But now Denmark has a new title: the happiest country in the world, according to the 2016 World Happiness Report.
The report chose countries considering the following six factors (因素): GDP per capita (人均生產總值), healthy life expectancy (平均壽命), low government corruption (腐化), a sense of social support, freedom to make life choices and a culture of generosity (慷慨).
Denmark is neither the richest nor the biggest country.u So why do the 5.7 million people of Denmark smile so much?
“We have no worries. And if we do worry, it’s about the weather. Will it rain today, remain grey or get cold?” Knud Christensen, a 39-year-old social worker from Copenhagen, explained to the Independent.
Denmark has a series of policies (**) that benefit its people. For example, the country supports parents if they want to be with their children, especially newborn babies. Danish families receive a total of 52 weeks of parental leave (育嬰假). While American women only have an average of 10.3 weeks.
Besides, women in Denmark don’t need to worry about whether they are treated unfairly by their male colleagues (男同事). In Denmark, gender equality (性別平等) is the priority (優先). In 1915, the country gave women the right to vote (選舉). You also see women in the political world. The country now has its first female prime minister (**), Helle Thorning-Schmidt.
The Nordic country is also famous for its biking culture. In Denmark’s capital, Copenhagen, bikes are used for about 50 percent of its people’s trips to school or work. Biking is not only good for reducing environment pollution, but it’s also good for people’s health. Just 30 minutes of biking a day adds an average of one to two years to a person’s life expectancy, The Huffington Post reported.
1. The report chose the happiest country according to the following factors EXCEPT _____.
A. their people’s looks
B. GDP per capita
C. their people’s life expectancy
D. a culture of generosity
2. What does the weather example want to show?
A. Danish people don’t like rain.
B. Danish people hate cold weather.
C. Denmark often has bad weather.
D. Danish people don’t worry much.
3. In Denmark, _____.
A. women don’t like to work
B. people enjoy some good policies
C. men and women are treated unfairly
D. women don’t have the right to vote

“Well, we’re in our new house. Let’s get a new pet to get along with it,” Mrs Brown said to her husband.
“That sounds like a pretty good idea,” he answered. “Do you want to see the ads in the newspaper?”
“Let’s go to the animal shelter. Many pets there need homes. Since tomorrow is Saturday, we can both go,” she said.
Next morning the Browns met Mr Snow at the animal shelter. “We want to be sure that the pets here go to good homes,” Mr Snow said, “So I need to ask you some questions.”
After they talked for a while, the Browns decided to get a small dog. It wouldn’t need a big house or a big yard. A small dog would bark(吠) and warm them if someone tried to break into their house. After Mr Snow gave the Browns a book on pet care, they chose one and wanted to take her home right away. But the animal doctor hadn’t checked her yet. So Mr Snow told them to return on Sunday.
On Sunday afternoon the Browns went to the animal shelter. The animal doctor said, “Shadow has had all of her shots(預防針). She will be healthy.” The browns thanked the doctor and took Shadow home.

Older Volcanic Eruptions
Volcanoes were more destructive in ancient history, not because they were bigger, but because the carbon dioxide they released wiped out life with greater ease.
Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions and mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300 million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do. He calculated the "killing efficiency" for these volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that for size, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.
The Permian extinction, for example, which happened 250 million years ago, is marked by floods of volcanic rock in Siberia that cover an area roughly the size of western Europe. Those volcanoes are thought to have pumped out about 10 gigatones of carbon as carbon dioxide. The global warming that followed wiped out 80 percent of all marine genera at the time, and it took 5 million years for the planet to recover. Yet 60 million years ago, there was another huge amount of volcanic activity and global warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years. "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid. He thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of CO2.
Vincent Courtillot, director of the Paris Geophysical Institute in France, says that Wignall's idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they lasted. And it is impossible to tell whether the huge blasts lasted for thousands or millions of years. He also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, and that lava volume may not necessarily correspond to carbon dioxide emissions.
1.Why did older volcanic eruptions do more damage than more recent ones?
A. Because they killed off life more easily.
B. Because they were brighter.
C. Because they were larger.
D. Because they were hotter.
2.How did Wignall calculate the killing power of those older volcanic eruptions?
A. By estimating how long they lasted.
B. By counting the dinosaurs they killed.
C. By studying the chemical composition of lava.
D. By comparing the proportion of life wiped out with the volume of lava produced.
3.When did dinosaurs become extinct?
A. 300 million years ago.
B. 250 million years ago.
C. 60 million years ago.
D. 65 million years ago.
4. What can be inferred from paragraph 3 concerning dinosaurs?
A. They were killed off by an asteroid.
B. They died of drastic climate change.
C. They were wiped offby a volcanic eruption.
D. The cause of their extinction has remained a controversial issue.
5.What is the main thesis of the article?
A. Volcanic eruptions are not always deadly.
B. Older volcanic eruptions were more destructive.
C. Carbon dioxide emissions often give rise to global warming.
D. It is not easy to calculate the killing power of a volcanic eruption.

3.D。細節題。題干：恐龍是什么時候**的?利用題干關鍵詞可以定位到第三段。***這么一句話：He ignored the extinction which wiped out the dinosaurs 65 million years ago，because many scientists believe it was primarily caused by the impact ofan asteroid.(他沒有提及6500萬年前恐龍的`**，因為許多科學家相信恐龍的**是受一顆小行星的影響)。
4.D。細節題。題干：從第三段還可以推導出有關恐龍的什么樣的信息?在討論第三題的答案時，我們已經注意到了，Wignall沒有提6500萬年前恐龍的**是否跟火山爆發有關，因為許多科學家相信恐龍的**是受一顆小行星的影響。這就說明，關于恐龍**的原因在科學家之間是有爭議的。
5.B。主旨題。問題問的是：文章的主要論點是什么?答案在文章的第一句：Volcanoes were more destructive in ancient history(古代火山更具破壞力)。
