Stephen Warren, study leader at the University of Washington, has been on the case of the green icebergs for more than 30 years. He first took samples from one of these green hunks of ice in 1988, near the Amery Ice Shelf, East Antarctic. Most glacial ice occurs in shades of white to brilliant blue. The bluer the ice, the older it is. Typically, compression (压缩) from accumulating layers of snow pushes air bubbles out of the ice, reducing the scattering of white light. The compressed ice absorbs most of the light except for blue, creating the blue color seen in the hearts of icebergs and glaciers.

The green ice was similarly bubble-free, and yet it looked green instead of blue. Warren and his team soon found that the green ice came not from glaciers, but from marine ice. That's the ice from the undersides of floating ice shelves.

At first, the team thought that organic material in the marine ice was causing the green color. But further research showed that the green marine ice didn't have a higher — than — usual amount of organic impurities. Now, a new study finds that a different sort of impurity may be the root cause of the green ice. Warren and his colleagues report that the marine ice at the bottom of the Amery Ice Shelf has 500 times more iron than the glacial ice above.

This iron comes from the rocks under the Antarctic Ice Sheet, which are turned into fine powder as glaciers move over them. The icebound iron oxidizes (氧化) as t contacts seawater. The resulting iron oxide particles take on a green color when light scatters through them. When icebergs break off the larger ice shelf, they carry this iron-rich ice with them. It's like taking a package to the post office. The iceberg can deliver this iron into the ocean far away, and then melt and deliver it to other living things that can use it as a nutrient.

(1)、What's special about the iceberg found by Warren?
A、The iceberg was old. B、The iceberg absorbed blue light. C、The iceberg's heart was pure white. D、The iceberg was bubble-free and green.
(2)、What's the actual reason for the green color of some Antarctic icebergs?
A、Impurities of marine ice. B、Reflection of green plants. C、Iron dust from marine ice. D、Compression from layers of snow.
(3)、What's the function of the iron mentioned in the last paragraph?
A、Deliver the package. B、Bring marine life nutrients. C、Oxidize the seawater. D、Break off the large ice shelf.
(4)、What can be a suitable title for the text?
A、A Study About Antarctic B、The Colors of Icebergs C、The Movement of the Icebergs D、The Mystery of the Green Icebergs

    I set out to change the lives of those who need help by joining my school's newly formed Free The Children Club. Through the determination of friends, the group has grown bigger and stronger each year. Over the past two years my friend, Alex Auclair, and I have become the leaders of the club.

    Already, after only two years of fundraising, we have accumulated over three thousand dollars and almost two thousand food items through various fundraising efforts. For example, each year a 24-hour famine (饥饿) is planned resulting in absolutely no consumption (消耗) of food. By taking part in these activities, we put ourselves in the shoes of someone living in poverty.

      No money raised goes to waste. At the end of each school year, the group takes a vote to determine where our funds will be spent and donated. Last year, we bought enough desks, chairs, supplies and textbooks for every student in a Kenyan school. This year, we plan to spend our earning helping out families in Sierra Leone.

    Poverty is a worldwide issue affecting the lives of people in not only developing countries, but also first-world countries such as Canada, the United Kingdom and Japan. Living in poverty can result in hunger, many forms of disease, lack of education, and for millions, death. It does not have to be this way. You too can form a club like the Free The Children Club or you can participate in events outside of school. Get your friends, family, even your community involved in fundraising. Do what you can to change the world.

    The United Arab Emirates (UAE) is mostly a desert. However, this has not stopped the country from creating great building projects. On September 26, UAE officials announced another ambitious project — Mars Science City. Expansive deserts and miles of coastline provide plenty of options for safe rocket launches (发射). And its position on the Earth makes it especially appealing as the spin of the Earth provides an extra push, meaning less fuel is needed to get payloads into orbit. All these seem to make it possible.

    The Mars City Project, designed by Bjarke Ingels Group, or BIG, will provide a realistic model to simulate (模仿) living on the surface of Mars, the red planet. It is part of the UAE's Mars 2117 Project to lead the global race to land humans on Mars and be the first to build a settlement there. Sheikh Mohammed bin Rashid, Prime Minister and ruler of Dubai, says, “The UAE seeks international support to develop technologies that benefit humans, and lay the foundation of a better future for more generations to come.”

    Built outside Dubai, the 1.9 million square feet city is expected to cost $135 million. It will consist of several dome-shaped laboratories, similar to the ones imagined for the first Mars settlers. Scientists from around the word will be invited to conduct research to come up with methods to create food, water and energy, using techniques which can be copied onto the red planet. The living spaces, where the researchers can live for up to a year, will simulate the planet's conditions as much as possible.

    The research city will also include a museum featuring famous space achievements to help educate and inspire children to undertake space exploration and discovery. To discover whether the construction method works on Mars, the museum's walls will be 3D printed using the sand from the nearby desert. Now, if they would only add some living quarters for the general public to experience life on Mars without leaving Earth, life would be perfect.

    My friend, Jack, was a taxi driver. We became friends quite by accident. Five years ago, I made a trip to Chicago. The moment I stepped into a cab, I realized it was different. The floor was covered with a rug (小地毯). There were small reproductions of paintings by Van Gogh inside the cab. And the windows were spotless. I told the driver I had never ridden in a more attractive taxi.

    "I like to hear my passengers say that," he replied. "How long have you been decorating your cab?" I asked. "It's not mine," he said. "It's a company cab. I hit upon the idea years ago when I worked as a clean-up man for the taxi company. Each car that came in at the end of the day was like a garbage pit. Cigarette butts and matches covered the floor. Sticky stuff like peanut butter was on the seats or door handles. I thought that if the company and the drivers would give people a car worth keeping clean, they might be more considerate."

    "As soon as I got my taxi license, I tried out my ideas. I put a lot of extra decorations into the cab they gave me to drive. I got a nice rug and some flowers. When each passenger got out, I checked to make sure that everything was in order for the next fare. After about a month of my bringing in a spotless cab, the boss reserved the same car for me each day. That was when I put up the reproductions of great paintings."

    "I've never been disappointed by people in the past ten years—no garbage. Like I say, people appreciate beautiful things. If we planted more flowers and trees in the city and made the buildings more attractive, more people would tend to keep the city clean."

    Later, we became good friends. I was impressed by the taxi-driver, who had hit on a great truth—a sense of beauty comes with the gift of life. Most people don't have to be instructed about the rarity of beauty. They respond when they find it. And, if they are made to feel a part of it, they will try to add to it.

    Before the 1830s, most newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper"-a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

    This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830,but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny-usually two or three cents was charged-and some of the older well-known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.

With advanced communication technologics making the iconic British red telephone boxes expendable (可抛弃的), a US firm is all set to bring them back to use. Call boxes would be changed into mini-offices for workers on-the-go and will offer free coffee to subscribers (认购者).

Bar Works Inc's chief executive Jonathan Black, a Briton living in New York, said that his company will renew telephone boxes with fully functional printers, scanners, 25-inch screens and Wi-Fi. Bar Works specializes in offering bar-themed work stations in prime locations, charging customers with a monthly subscription in return for free access to the business and office supplies. The company plans to operate in a similar manner, offering British customers with monthly memberships to "Pod Works" for £19.99 ($29).

The company will refit telephone boxes in five major British cities and has already rented and changed 15 old call boxes in London and Edinburgh. As expected, they are coming into use by the public in the coming months. "Given the prime location, above all else, of the telephone boxes, the launch is expected to gain at least 10, 000 members by the end of 2021. It's an alternative to, say, Starbucks but obviously it provides you with total privacy. " said Black.

Thanks to mobile phones, the red telephone boxes have been effectively made expendable. According to a report by the Daily Mail, retired telephone boxes, especially those damaged deliberately, are sent to a "telephone box graveyard" of sorts, where they take great pains to restore to their former glory before being sold to collectors across the globe. Such is the demand for properly restored telephone boxes, that it is not uncommon for them to be sold for amounts as high as £10, 000.

Despite its setback, in a recent survey, the British red telephone box, which was originally designed in 1920, was voted the greatest British design of all time.
