Scientists are learning new things about Antarctica, the coldest place on Earth. For example, the Antarctic ice sheet is shrinking. A new study found that summer ice loss in parts of Antarctica was at its highest level in 1,000 years. The study showed that Antarctic ice was melting mostly from below ice shelves, where the water is warmer than the ice.
Eric Rignot is an earth system expert at the University of California, Irvine. He also works for the American space agency, NASA. There he serves as senior research scientist at NASA’s Jet Propulsion Laboratory, also in California. He says ice melting from below is responsible for 55 percent of the shelf loss from 2003 to 2008. That is a much higher rate than scientists thought earlier.
Professor Rignot and his team used satellite observations, radar and computer models to measure features above the ice to learn what was going on below.
The measurements show differences from one area to the next around the continent. The major ice shelves are called Ross, Filchner and Ronne. They make up two-thirds of Antarctica’s ice shelves. But they are responsible for only 15 percent of the melting ice.
The professor says even small changes, like changes in ocean flow driven by wind, can make a huge difference in the melting of the ice shelf.
Sixty percent of the Earth’s fresh water is held in the huge Antarctic ice sheet. Professor Rignot says the study will help experts predict how the continent reacts to warmer ocean waters and helps to cause rising sea levels around the world. The study was published in the journal Science.What’s the main idea of the passage?

Ten years ago I went into the studio and recorded a 56-minute video for teenagers called “Three keys to greatness.” Although my focus was for teenagers, the principles I shared certainly apply to adults as well. Recently I was asked to list these three things. Now for your benefit here they are again.
Firstly, set goals. I call it the view of the future. Most people, including kids, will pay the price if they can see the promise of the future. So we need to help our kids see a clear future, and they will be ready to pay the price today to attain the rewards of tomorrow. Goals help them do this.
Secondly, pay attention to personal development. Simply making consistent investments in our education and knowledge we will benefit throughout our lives. I suggest having an amount of time set aside for reading books, listening to recording, attending discussion, keeping a journal and spending time with other successful people. Mr Jones recommends reading a lot as a good method of improving yourself. The simple fact is that you need to change your outlook on life and on yourself, as it will have a positive influence on your personality and outlook. You should learn something new about your profession every single day until you’re an expert in the field.
Thirdly, make a financial plan. I call it the 70/30 plan. After receiving your salary, simply setting aside 10% for saving, 10% for investing and 10% for giving, the rest for your life. And over time when you have your own family this will guarantee financial independence for you.
If people focus on doing these three simple things over a long period of time, I believe they will be surely successful! The advantage of setting goals is that ___.
| A.you’ll know the future of the world |
| B.you’ll know what kind of person you will become |
| C.you’ll be willing to work hard for your future |
| D.you’ll be satisfied with what you have achieved |
The author lays the most stress on ___.
| A.gaining knowledge |
| B.making good friends |
| C.attending discussions |
| D.listening to recordings |
According to the passage, one picture of reading a lot is to ___.
| A.lead a better life |
| B.have a good personality and outlook |
| C.change your position |
| D.become an expert in many fields |
Whom does the author mainly advise to make a financial plan?
| A.All kinds of people |
| B.The young people |
| C.The middle-aged people |
| D.The rich people |
The Queen’s English is now sounding less upper-class, a scientific study of the Queen’s Christmas broadcasts has found. Researchers have studied each of her messages to the Commonwealth countries since 1952 to find out the change in her pronunciation from the noble Upper Received to the Standard Received.
Jonathan Harrington, a professor at Germany’s University of Munich, wanted to discover whether accent changes recorded over the past half century would take place within one person. “As far as I know, there just is nobody else for whom there is this sort of broadcast records,” he said.
He said the noble way of pronouncing vowels (元音) had gradually lost ground as the noble upper-class accent over the past years. “Her accent sounds slightly less noble than it did 50 years ago. But these are very, very small and slow changes that we don’t notice from year to year.”
“We may be able to relate it to changes in the social classes,” he told The Daily Telegraph, a British newspaper. “In 1952 she would have been heard saying ‘thet men in the bleck het’. Now it would be ‘that man in the black hat’. Similarly, she would have spoken of ‘the citay’ and ‘dutay’, rather than ‘citee’ and ‘dutee’, and ‘hame’ rather than ‘home’. In the 1950s she would have been ‘lorst’, but by the 1970s ‘lost’.”
The Queen’s broadcast is a personal message to the Commonwealth countries. Each Christmas, the 10-minute broadcast is put on TV at 3 p.m. in Britain as many families are recovering from their traditional turkey lunch.
The results were published in the Journal of Phonetics.What is the text mainly about?
| A.The relationship between accents and social classes. |
| B.The Queen’s Christmas speeches on TV. |
| C.The changes in a person’s accent. |
| D.The recent development of the English language. |
The Queen’s broadcasts were chosen for the study mainly because ___.
| A.she has been Queen for many years |
| B.she has a less upper-class accent now |
| C.her speeches are familiar to many people |
| D.her speeches have been recorded for 50 years |
We may infer from the text that the Journal of Phonetics is a magazine on ___.
| A.speech sounds | B.Christmas customs |
| C.TV broadcasting | D.personal messages |
Which of the following is an example of a less noble accent in English?
| A.“dutay” | B.“citee” | C.“hame” | D.“lorst” |
Most likely, you aren’t the family breadwinner. But doing a small job or getting a weekly allowance would put some money in your pocket. For kids and grown-ups alike money is easy to spend. If you aren’t careful, it can be gone in no time.
Being responsible with your money is an important skill to learn and the sooner you start the better. Whether you are tracking your spending or saving for something special, creating a budget can help you deal with expenses and plan for the future. All you need are paper and a pencil and some self-control.
First, take a look at our sample monthly budget. Then, use a separate sheet of paper to plan your own. In the first two columns, list your sources of income and how much you expect to earn from them. In the third and fourth columns, list what you expect to spend your money on and the amount.

Far from the land of Antarctica, a huge shelf of ice meets the ocean. At the underside of the shelf there lives a small fish, the Antarctic cod.
For forty years scientists have been curious about that fish. How does it live where most fish would freeze to death? It must have some secret. The Antarctic is not a comfortable place to work and research has been slow. Now it seems we have an answer.
Research was begun by cutting holes in the ice and catching the fish. Scientists studied the fish’s blood and measured its freezing point.
The fish were taken from seawater that had a temperature of -1.88°C and many tiny pieces of ice floating in it. The blood of the fish did not begin to freeze until its temperature was lowered to -2.05°C. That small difference is enough for the fish to live at the freezing temperature of the ice-salt mixture.
The scientists’ next research job was clear: Find out what in the fish’s blood kept it from freezing. Their search led to some really strange thing made up of a protein never before seen in the blood of a fish. When it was removed, the blood froze at seawater temperature. When it was put back, the blood again had its antifreeze quality and a lowered freezing point.
Study showed that it is an unusual kind of protein. It has many small sugar molecules (分子) held in special positions within each big protein molecule. Because of its sugar content, it is called a glycoprotein. So it has come to be called the antifreeze fish glycoprotein, or AFGP.Why can the Antarctic cod live at the freezing temperature?
A. The seawater has a temperature of -1.88°C.
B. It loves to live in the ice-salt mixture
C. A special protein keeps it from freezing.
D. Its blood has a temperature lower than -2.05°C.What does the underlined word “it” in Paragraph 5 refer to?
| A.A type of ice-salt mixture. |
| B.A newly found protein. |
| C.Fish blood. |
| D.Sugar molecule. |
What does “glyco-” in the underlined word “glycoprotein” in the last paragraph mean?
| A.sugar | B.ice | C.blood | D.molecule |
What is the best title of this passage?

If you were to walk up to Arthur Bonner and say, “Hey, Butterfly Man,” his face would break into a smile. The title suits him. And he loves it.
Arthur Bonner works with the Palos Verdes blue butterfly, once thought to have died out. Today the butterfly is coming back — thanks to him. But years ago if you’d told him this was what he’d be doing someday, he would have laughed, “You’re crazy.” As a boy, he used to be “a little tough guy on the streets”. At age thirteen, he was caught by police for stealing. At eighteen, he landed in prison for shooting a man.
“I knew it had hurt my mom,” Bonner said after he got out of prison. “So I told myself I would not put my mom through that pain again.”
One day he met Professor Mattoni, who was working to rebuild the habitat (栖息地) for an endangered butterfly called El Segundo blue.
“I saw the sign ‘Butterfly Habitat’ and asked, ‘How can you have a habitat when the butterflies can just fly away?’” Bonner recalls. “Dr. Mattoni laughed and handed me a magnifying glass (放大镜), ‘Look at the leaves.’ I could see all these caterpillars (蝴蝶的幼虫) on the plant. Dr Mattoni explained, ‘Without the plant, there are no butterflies.’”
Weeks later, Bonner received a call from Dr. Mattoni, who told him there was a butterfly that needed help. That was how he met the Palos Verdes blue. Since then he’s been working for four years to help bring the butterfly back. He grows astragalus, the only plant the butterfly eats. He collects butterflies and brings them into a lab to lay eggs. Then he puts new butterflies into the habitat.
The butterfly’s population, once almost zero, is now up to 900. For their work, Bonner and Dr. Mattoni received lots of awards. But for Bonner, he earned something more: he turned his life around.
For six years now Bonner has kept his promise to stay out of prison. While he’s bringing back the Palos Verdes blue, the butterfly has helped bring him back, too.When he was young, Arthur Bonner ___.
| A.broke the law and ended up in prison |
| B.was fond of shooting and hurt his mom |
| C.often laughed at people on the streets |
| D.often caught butterflies and took them home |
Bonner came to know the Palos Verdes blue after he ___.
| A.found the butterfly had died out |
| B.won many prizes from his professor |
| C.met Dr. Mattoni, a professor of biology |
| D.collected butterflies and put them into a lab |
From the last sentence of the text, we learn that raising butterflies has ___.
| A.made Bonner famous | B.changed Bonner’s life |
| C.brought Bonner wealth | D.enriched Bonner’s knowledge |
Which of the following would be the best title for the text?
| A.A Promise to Mom | B.A Man Saved by Butterflies |
