No longer in the pink

Corals are comeback creatures. As the world froze and melted and sea levels rose and fell over 30,000 years, Australia’s Great Barrier Reef, which is roughly the size of Italy, died and revived five times. But now, thanks to human activity, corals face the most complex condition they have yet had to deal with.

According to the Intergovernmental Panel on Climate change, a rise in global temperatures of 1.5oC could cause coral reefs to decline 70-90%. The planet is about 1oC hotter than in the 19th century and its seas are becoming warmer, stormier and more acidic. This is already affecting relations between corals and the single-celled algae (海藻), which give them their color. When waters become unusually warm, algae float away, leaving reefs a ghostly white. This “bleaching” is happening five times as often as it did in the 1970s. Meanwhile the changing chemistry of the oceans makes it harder for corals to form their structures.

If corals go, divers and marine biologists are not the only people who will miss them. Reefs take up only a percent of the sea floor, but support a quarter of the planet’s fish diversity. The fish that reefs shelter are especially valuable to their poorest human neighbors, many of whom depend on them as a source of protein. Roughly an eighth of the world’s population lives within 100km of a reef. Corals also protect 150,000km of shoreline in more than 100 countries and territories from the oceans buffeting, as well as generating billions of dollars in tourism revenue.

Coral systems must adapt if they are to survive. They need protection from local sources of harm. Their eco-systems suffer from waste from farms, building sites and blast fishing. Governments need to impose tighter rules on these industrials, such as tougher local building codes, and to put more effort into enforcing rules against overfishing.

Setting up marine protected areas could also help reefs. Locals who fear for their livelihoods could be given work as rangers with the job of looking after the reserves. Visitors to marine parks can be required to pay a special tax, like what has been done in the Caribbean.

Many reefs that have been damaged could benefit from restoration. Coral’s biodiversity offers hope, because the same coral will grow differently under different conditions. Corals of the western Pacific, for example, can withstand higher temperatures than the same species in the eastern Pacific, which proves a way forward to encourage corals to grow in new spots.

Just as John Lubbock said, we may sit in a library and yet be in all quarters of the earth. Here are some of the coolest libraries of the world.

Stuttgart City Library

Despite a classic white-on-white color, Stuttgart City Library is one of the most visually appealing modern libraries. The amazing modem and simple look is the product of the Korean architect Yi Eun-young. The German library opened in 2011, and cost nearly 80 million euros to construct.

Kanazawa Umimirai Library

Architects from the Coelacanth K&H Architects studio designed the Kanazawa Umimirai Library lo create the best reading environment. Healed floors, an outpouring of natural light, and other features were specifically included lo achieve this goal. The wall, which consists of thousands of tiny openings, allows natural lighting into the building, improving the overall feel of the space. This Japanese library was opened in 2011, and reflects the appearance of many modem and simple spaces.

Library of Congress

In 1800, Congress set up the Library of Congress in Washington D.C.. Fifteen years later, Thomas Jefferson offered his personal library to replace books that were lost when the British set the building on fire in 1814. His books, which took nearly 50 years to collect, varied from texts on science, literature and philosophy, to books in a variety of foreign languages. These days, the Library of Congress offers more than 155 million items and the largest rare book collection in North America.

State Library of Victoria

The Slate Library of Victoria, located in Melbourne, Australia, is one of the largest exhibiting libraries in the world. Though it opened in 1856, major repairs took place between 1990 and 2004. The La Trobe Reading Room is one of the library’s main attractions due to its visually amazing architecture. The lawn at the library’s front attracts hundreds of city folk each day, who gather for lunch or to enjoy the statues there. The library currently contains over two million books, as well as armor (盔甲) of Ned Kelly, a folk hero against the ruling class.

C

There is not enough oil in the world now. As time goes by, it becomes less and less, so what are we going to do when it runs out? Perhaps we will go back to using horses, carriages and bicycles.

In the Second World War, some people didn’t use gas made from petroleum (石油) in their cars. They made gas from wood and plants instead. The car didn’t go fast, but they ran, so this was better than nothing. However, in the future, we can’t cut down all our trees to make gas; we need our trees for other things, too.

Besides different types of gas, we can also use electricity to run our cars, but first we must make the electricity! Some countries have coal and they make electricity with that, but we might not always have coal, either. Other countries have big, strong rivers, and they can use the power of water to turn turbines (涡轮机) and make electricity more easily and cheaply.

We are also able to get power from the ocean tides. We put turbines into the mouth of the river. Then the tide comes in, the water turns the turbines and then it goes out, it turns them again.

Which of these ways will be used to run our cars in the future?

49. When might people have to go back to using horses and carriages?

A. When they are poor.                                    B. When they run out of oil.

C. When they need more exercise.               D. When there aren’t any big trees in the world.

50. What did some people use to make gas in the Second World War?

A. Water                         B. Coal                        C. Wood and plants          D. Tides

51. How many ways are suggested to make electricity in the passage?

A. 2                                 B. 5                             C. 4                                      D. 3

52. The passage is mainly about ________ .

A. how to run our cars                                          B. what to do when oil runs out

C. different types of gas                                  D. the ways to make electricity

In space, there is no up or down. Without the gravity that we experience on Earth, as-tronauts and everything else on a spaceship float freely.

Humans can experience the sense of zero gravity without going into space. How？A zero-gravity flight. When an airplane flies in a lot of parabolas（抛物线）, a man-made zero-gravity environment is set up. Everything in the plane floats, even passengers.

Gravity has an effect on everything from the human body and mind to the behavior of plants and the way machines run. Space travel is expensive and dangerous. But zero-gravity flights let scientists conduct experiments in an environment that mimics（模拟） the conditions of space. On each of its research trip, Zero-G flies about 30 parabolas, each of which creates a period of weightlessness that lasts about 30 seconds. Nikolaus Kuhn of the University of Ba-sel, in Switzerland, flew with Zero-G. He was conducting an experiment about soil and the flow of water on Mars. The Red Planet has about one-third of the gravity that Earth has. This means water flows more slowly on Mars. By making the parabolas less steep, zero-gravity flights can make the feeling of Martian gravity. Flying with Zero-G has been necessary for Kuhn’s research. “It is the only chance, other than going to Mars, to mimic movement of water as it would be on Mars,” he told TFK.

For years, NASA used zero-gravity flights to prepare and train astronauts. “I have not been to space,” Peters of Zero-G says, “But I have been told by astronauts that zero-gravity feels exactly the same.” As humans continue to explore the universe beyond Planet Earth, zero-gravity flights will remain an important and fun tool. “It never gets old,” Peters says “I would do it every weekend for the rest of my life if I could.”

1.Why do scientists set up man-made zero-gravity environment？

A.To study the water on the earth.

B.To offer weightlessness as a business.

C.To take scientists to any other planets.

D.To mimic the condition of space for experiments.

2.How much time of weightlessness can a Zero-G light offer？

A.About 30 seconds. B.About 90 seconds.

C.About 15 minutes. D.About 30 minutes.

3.What feature do the parabolas in Zero-G flights have？

A.The gentler parabolas are, the more satisfied the researchers are.

B.The steeper parabolas are, the less weight the passengers feel.

C.The steeper parabolas are, the more successful the experiments are.

D.The gentler parabolas are, the more quickly water on Mars flows.

4.What can be inferred about the Zero-G flight from the text？

A.It is useless for training astronauts.

B.It has no side effect on human body.

C.It creates a substitutable environment of zero gravity in space.

D.It is cheaper but more dangerous than space travel.
