1、第一单元一：In 1980, Tim Samaras was working at the University of Denver Research Institute when he first saw the camera. Weighing 1,600 pounds and standing six feet high, the Beckman & Whitley 192 camera was hard to Miss. The camera was used to take pictures of nuclear tests, and it was part of Samaras j

2、ob to look after it. Samaras left the research institute and had other jobs, but he never forgot that camera. Twenty-five years later, he saw it was for sale. He bought it for just $600, the value of its metal parts.Now, he is using the camera to study lightning. With the help of money from National

3、 Geographic, he changed how the camera works. He replaced the film technology with digital sensors designed for deep space exploration. He also added new software written specially for the camera.He hopes the camera will help him take a photograph of the moment lightning starts. This is very difficu

4、lt and he has been trying to get that shot since 2006.The burst of light comes from close to the ground and moves up to the sky. It is traveling at a third of the speed of light and the start of this flash takes as little as 200 milliseconds.The camera is fast enough to take the picture, but he must

5、 also know where to point it and also “click” at the right time. Some people think he has no chance of getting the shot he wants. But Samaras is used to people telling him that what hes trying cant be done. Before he started to study lightning, he spent several years chasing after tornadoes. People

6、didnt think it was possible to record what it looks and feels like inside a tornado, but Samaras managed. He got some of the most accurate readings ever of wind speed, barometric pressure, temperature, and humidity.It is possible that he is right about how to photograph the start of lightning, too.

7、“Im still in hot pursuit of that image,” he said in 2012, adding, “And I wont stop until this is done.”二1What kind of people make good nurses?A: Well, you have to be organized. For example, Im in charge of my patients medicine. I have to give them the correct medicine, so I write everything down in

8、a chart. I get the medicine. Then, I check on my chart that its the correct one. Nobody gets the wrong medicine that way.Q: You are well organized!A: Thanks. It has a big effect on my patients health, so its important to me. Nurses also have to be fit because the work is very physical.Q: What kind o

9、f physical work do you do?A: I stand or walk all of the time, and sometimes I have to lift patients up from their beds.: Is teaching a difficult job?A: Sometimes it is. Although the students are wonderful, the school has a rule I dont like.Q: What kind of rule?A: Well, I teach math and science, and

10、I think theyre very important subjects. But students here dont have to take both subjects. They can take one or the other and still graduate.Q: Do you mean they can finish school and never take math, for example?A: Yes, they can. Its not a good idea, in my opinion.2: Is teaching a difficult job?A: S

11、ometimes it is. Although the students are wonderful, the school has a rule I dont like.Q: What kind of rule?A: Well, I teach math and science, and I think theyre very important subjects. But students here dont have to take both subjects. They can take one or the other and still graduate.Q: Do you me

12、an they can finish school and never take math, for example?A: Yes, they can. Its not a good idea, in my opinion.3What does an engineer do every day?A: Well, there are many kinds of engineers. Im an industrial engineer. I look at our processes here at the factory, and I search for any problems.Q: Wha

13、t do you do if you find a problem?A: I give a presentation to my managers. We have a meeting, and I explain the problem to them. We try to find ways to solve it.Q: What happens next?A: They usually follow my suggestions.Q: So the managers here have a lot of respect for you.A: Yes, I believe they do

14、respect me. Its one of the reasons I like my job.三：Annie Griffiths is famous for her beautiful photographs. The photos come from countries all over the world, so its just a normal part of life for Griffiths to travel. Living in other countries is not for everyone, but for Griffiths and her children,

15、 its an adventure. Her children especially love the Middle East, and their experiences in that part of the world helped them to learn about other cultures. Griffiths work can also be dangerous. Traveling is not always safe. In the Galpagos Islands, Griffiths found herself in the water with sharks on

16、e day! Besides writing and taking pictures, Griffiths teaches photography skills to people who want to become photographers. They know they are learning from one of the best photographers in the World.第二单元一Im Miranda. I dont have much free time because I have a full-time job as a sales manager. I al

17、so have children, so I like to spend time with them. Sometimes we go to the beach, and sometimes we go to the park. For me, playing with my children has some importantbenefits: It makes me feel young and gives me great joy. My name is Mike. Im a first-year literature student of the University of Pen

18、nsylvania. I enjoy taking walks in the park. I love the outdoorsseeing the trees and feeling the sun on my face. Basically, Im always moving. Walking is good exercise. All that exercise keeps me healthy.My name is Cindy. What do I do in my free time? Well, my hobby is cooking. Its a pretty common ho

19、bby, so I know a lot of other people who like to cook. Sometimes my friends come over and we cook together. We laugh and tell stories!Im Tim. Im a teacher. When I want to relax, I listen to music at home. My favorite music is classical, especially Mozart. Theres only one drawback to spending my free

20、 time at home: I almost never spend time outside.二In a big city such as Paris, people need places to live, shop, and work. Empty space can be hard to find. But the city government finds and keeps these empty spaces. People need places to spend their free time, and parks are places that most people e

21、njoy.The city of Paris spends a lot of money to create more parks and gardens. Some people think that the cost is a big drawback. So, why does the city do this? What are some of the benefits of parks and other green spaces? Better Health. Having places to relax after work helps people feel good. Par

22、ks allow people to get exercise such as walking and jogging. Being outdoors in the sunlight is good for people. Better Environment. Trees help to clean the air and make cities cooler. Clean air helps people stay healthy. Less Crime. Crime, such as robbery and murder, is common in big cities. Researc

23、h says that there is less crime in places with green areas around them. Improved Education. Parks are also a place for children to learn and play together. According to one study, children learn better after they play in a park.三New research says that apes laugh when they are tickled. Researchers at

24、 the University of Portsmouth led a “tickle team”. The group of researchers tickled the necks, feet, hands, and armpits of young apes. The team recorded more than 800 of the resulting laughs on tape. The research suggests that the apes panting noise is the sound of laughter. They think that this pan

25、ting is the basis for human expressions of joythe “ha-ha” sound we make when we laugh. When we find something funny, such as a joke, we laugh. When apes find something funny, such as a tickle, they laugh. Humans find many situations funnysuch as jokes, tickles, TV comedy showsbut we are not unique b

26、ecause animals laugh, too.第三单元一二三第四单元一What is your house made of? Building a house from concrete or metal requires large amounts of energy and pollutes the air. Building a house from wood means cutting down trees and damaging the environment. Builder Michael Furbish has another idea: Use straw to ma

27、ke buildings. “Most other building materials require a lot of energy use in production and manufacturing at a factory,” explains Furbish. Straw is a kind of grass, and it takes little energy to grow. Its not very nutritious for animals, however, so farmers normally dry it and use it for animals to s

28、leep on.After the straw is dry, farmers use a machine to make baleslarge rectangular bricks of straw. Then, builders such as Furbish build walls with the bales. When they finish the walls, they cover them with plaster inside and outside. That keeps out water as well as insects and small animals. Fur

29、bish used about 900 straw bales for his familys two-story, three-bedroom house. His company used about 4,000 bales to build an elementary school in Maryland, U.S.A.Do you think a straw-bale house is for you? You wont know until you try living in one, but for Furbish, its a greener way to build.二Q: W

30、hat are vacation homes?A: Theyre usually houses or condominiums. Families only use these homes during vacations, so they want them to be in beautiful locations.Q: Why is Baja California popular for vacations?A: It has coasts on the Pacific Ocean and the Sea of Cortez, so tourists can enjoy sea life

31、such as dolphins, whales, and unusual fish. Its beautiful mountains and deserts are also excellent for hiking and sightseeing.Q: Can anyone own a home in Baja California?A: Yes. You dont have to be a Mexican citizen to own property here. Many vacation homes belong to people from other countries, esp

32、ecially Canada and the United States.Q: Are there a lot of new vacation homes for sale?A: Yes. Most of Baja Californias population lives in the north, in cities such as Tijuana and Mexicali. Recently, though, there has been rapid growth in the south, especially near Cabo San Lucas and La Paz. They w

33、ant to build a lot of new houses and hotels quickly in those places.Q: Is everyone happy about the housing growth?A: No. Some people worry about damage to the environment as more and more people move in. Baja California is also very dry, so having enough drinking water for everyone is another concer

34、n.三In Barcelona, Spain, both visitors and residents of the city know about the architect Antoni Gaud. The Casa Mil is perhaps his best-known building. From the outside, the walls look like natural stone. On the roof, several large, unusual works of art are actually chimneysthey carry away gases from

35、 cooking and heating from inside the apartments. The Casa Batll is another of Gauds apartment buildings. The outside of the building is very colorful, and its easy to see that Gaud was an artist as well as an architect. Not every apartment is spacious, but each apartment has a balcony, so residents

36、can stand outside their bedrooms or living rooms and see the street below.第五单元一二三第六单元一Here on Earth, we like to look up at the stars in the night sky. In space, the stars look even more amazing! Astronaut Don Thomas flew into space on the space shuttle Columbia. He said later, “I could see many more

37、 stars. I also could see stars of different colors. Some are white. Others are blue, red, or yellow like our sun.”For most of us, stars in the night sky appear to twinkle. Thats because light from the stars travels through the earths atmosphere before we see it. Gases in the atmosphere are always mo

38、ving, and that makes the light from the stars look unsteady. In contrast, “Theydont twinkle in space,” says Thomas. “They look like steady points of light.” Our own sun is a yellow, average-sized star. It formed around 4.6 billion years agoprobably in a very large cloud of gas and dust called a nebu

39、la. Bits of gas and dust came together, and then gravity began to pull the gas and dust into a ball. As the ball grew larger, its gravity grew stronger. Over time, the gravity became so strong that the ball collapsed and the gas heated up. A star was born! Stars last a very long timefor millions or

40、even billions of years. Our sun will get cooler and die someday, but it wont happen any time soon. 二Telescopes of the pastAs far as we know, Galileo was the first astronomer to observe the moon, planets, and stars through a telescope. In the 17th century, telescopes were just glass lenses inside tub

41、es made of wood. The lenses were shaped by hand to make things appear larger. Soon, however, people wanted bigger telescopes to be able to see farther into space. Large glass lenses were heavy and didnt work well in a telescope, so in 1668, Isaac Newton invented something new: a telescope that used

42、a mirror to reflect light. Soon, reflecting telescopes became the first choice for astronomers.Telescopes of the presentAs telescopes became larger, it became necessary to put them inside some kind of building. Observatories, buildings with telescopes inside for doing research, were built as early a

43、s the 18th century. With these larger telescopes, astronomers discovered planets that Galileo never knew aboutUranus and Neptune.Three of todays largest observatories stand on top of Mauna Kea in Hawaii. At nearly 14,000 feet (4,300 meters), Mauna Kea is above 40 percent of the earths atmosphere. Th

44、e Keck Observatory is among the observatories on Mauna Kea, and the mirrors in its two reflecting telescopes are 33 feet (10 meters) across! Their size allows astronomers to see far into space.三Most of the worlds people now live in or near cities, where doing most things at night is as easy as doing

45、 them during the day. Seeing the stars at night, however, is not easy to do in a city. Streetlights and lights from businesses and advertisers shine into the night sky, and only the brightest stars can be seen.The dark-sky movement wants to change this. They argue that seeing the night sky is import

46、ant for everyonenot only forastronomers. They say that outdoor lighting affects human health and wildlife, and they recommend simple things such as streetlightsthat only let light shine down at the street, not up at the sky.第七单元一Taylor grew up in Asia and Europe. As a child, he often swam among Mala

47、ysias coral reefsplaces where small sea animals and plants grow on rocks or other solid objects on the ocean floor. Reefs are important for many kinds of ocean life, and theyre in troublebecause of fishing and climate change.These days, Taylor still likes to swim, and he is conscious of the need to

48、help ocean reefs and ocean life. His recent art project does exactly that. The Silent Evolution is a group of sculptures. Taylor used real people as models when he was making them. In a way, all the sculptures are copies of people, and they look just like them. The sculptures are in a public place,

49、but they are not easy to see. They are on the ocean floor near Cancn, Mexico. There are more than 400 of them, and together, they form one huge piece of art. Its especially interesting because the artist did not repeat any of the sculptureseach one is a sculpture of a different person. Taylors artwo

50、rk is constantly changing. Sea animals and plants make their homes on the sculptures just as they do on natural reefs, and in time, a new reef will form. That means the sculptures are temporary, and if you want to see them, you need to do it soon. Taylor hopes the new reef that forms over the sculpt

51、ures will last forever, or at least far into the future.二Elephant art began at zoos in the United States. Zookeepers there saw an elephant named Ruby using a stick to make marks in the dirt. They bought paints and brushes for her, and soon she was painting. In a book about Ruby, author Dick George says she loved to paint, and she even chose the colors.In Thailand, the Thai Elephant Conservation Center (TECC
