British scientists are breeding a new generation of rice plants that will be able to grow. in soil con??taining salt water. Their work may enable abandoned farms to become productive farms once more.
Tim Flowers and Tony Yeo, from Sussex University’s School of Biological Sciences,. have spent several years researching how crops, such as rice, could be made to grow in water that has become salty. The pairs have recently begun a three-year programme, funded by the Biotechnology and Bio??logical Sciences Research Council, to establish which genes enable some plants to survive salty condi??tions. The aim is to breed this capability into crops, starting with rice.
It is estimated that each year more than 10 million hectares (公頃) of agricultural land are lost because salt gets into the soil and stunts(防礙生長) plants. The problem is caused by several factors. In the tropics, mangroves that create swamps (沼澤) and traditionally formed barriers to sea water have been cut down. In the Mediterranean, a series of droughts have caused the water table to drop, allowing sea water to seep (滲透) in. In Latin America, irrigation often causes problems when water is evaporated by the heat, leaving, salt deposits behind.
Excess salt then enters the plants and prevents them functioning normally. Heavy concentrations of minerals in the plants stop them drawing up the water they need to survive.
To overcome these problems. Flowers and Yeo decided to breed rice plants that take in very little salt and store what they do absorb in cells that do not affect the plants’ growth. They have started to breed these characteristics into a new rice crop, but it will take about eight harvests before the resul??ting seeds are ready to be considered for commercial use.
Once the characteristics for surviving salty soil are known, Flowers and Yeo will try to breed the appropriate genes into all manners of crops and plants. Land that has been abandoned to nature will then be able to bloom again, providing much needed food for the poorer countries of the world.
4. Which of the following statements about Flowers and Yeo is true?
A. They are students at Sussex University. B. They are rice breeders.
5. Which of the following is NOT mentioned as a cause of the problem discussed in the passage?
A. Natural barriers to sea water have been destroyed.
B. The water table has gone down after droughts.
C. Sea level has been continuously rising.
D. Evaporation of water leaves salt behind.
6. The word "affect" in Paragraph 5 could be best replaced by________.
A. influence B. effect C. stop D. present
7. The attitude of the author towards the research project is________.
A. positive B. negative C. suspicious D. indifferent
4-7 DCAA
4. 推斷題。從第二段中的Tim Flowers and Tony Yeo，from Sussex University’s School of Biological Sciences，have spent several Years researching how crops，可知，他們是來自大學的老師，他們是搭檔，而不是夫妻，所以可以排除A項和C項；B項的意思更不正確。
5. 細節題。A項內容與文章中的traditionally formed barriers to sea water have been cut down一致，B項內容與文章中的a series of droughts have caused the water table to drop一致，D項 內容與文章中的when water is evaporated by the heat一致，而C項內容在文章中根本沒有談到。
6. 詞義題。我們可以根據句子的意思作出推斷。
7. 推斷題。從文章最后一段可以看出，作者對這種實驗是“肯定的”。主要表現在Land that has been abandoned to nature will then be able to. bloom again，providing much needed food for the poorer countries of the world，作者認為如果該實驗成功的話，廢棄的土地又會肥沃起來。

Australian Flag Designs by Readers of the Sun-Herald
We received dozens of responses after inviting readers to send in their designs for a new flag. The designs we received include:
James Anthony, Drummoyne
James reduces the Union Jack down in size and changes its shape to become a reminder of the British tradition rather than canceling it altogether. At the same time he suggests enlarging the stars of the Southern Cross. His design attempts to use the best of both worlds in a newly designed flag.
As he says, “the British part of the Australian Flag is too big and the Australian bits are too small. When you make the stars bigger the Australian flag can look impressive.”
Joe Bollen, Turranmurra
Joe’s flag has the main elements of a risen sun, white horizon(地平線), red earth at the base and the Southern Cross. He intends to make the risen sun a special Australian symbol on the flag. He believes it represents life. The Southern Cross shows that we live in the Southern Hemisphere. (半球)
Maria Ieraci, Sydney
Maria deleted the Union Jack but otherwise kept the flag as is with the Southern Cross and Federation Star. She says, ‘There is only one correct way to change the Australian flag” and that is “to drop the Union Jack ---- when Australia becomes a Republic”, which she hopes will be before 2010.
Ron Bennett, Sydney
Ron recommends using the Aboriginal colors but replacing their image of the sun with the map of Australia. He says, “Australia is unique being an island continent with an instantly recognizable outline at that” and “this will leave no doubt as to which country the flag belongs.”
【小題1】Which of the four designs can remind you of the past of the country?
| A．Joe’s | B．Maria’s | C．Ron’s | D．Jame’s |
| A．the spirit of the nation |
| B．the position of the country |
| C．the tradition of Britain |
| D．the expectations of the people |
| A．the British flag |
| B．A former British ruler |
| C．group of stars |
| D．A former symbol of Australia |

Robert Frost was one of America’s best known and most honored serious writers. But his fame came late in his life.
He was born in San Francisco, California in 1874. He lived in California during his early childhood. He was named after the chief Southern general in America’s Civil War. The general’s name was Robert Edward Lee. The poet was named Robert Lee Frost, because his father wanted to honor the general.
Someone once asked another American writer, Ernest Hemingway, how to become a writer. The best thing, he said, was to have an unhappy childhood. If this is true, Robert Frost’s childhood was unhappy enough to make him a very good writer. Robert Frost’s father was a reporter who wanted to be a politician. He often drank too much wine and became angry. Robert was the victim of his anger.
Robert Frost finished high school in 1891. After high school, Robert’s grandfather offered to pay his costs at Dartmouth College. But Robert left the school after a few months. He did not like it. He spent the next few years working at different jobs. At one time, he worked in a factory. Later, he repaired shoes. He was a teacher. He was a reporter. Always, he wrote poetry.
Robert Frost attended Harvard University for two years. After that, he returned to the many jobs he held before. For a while, Frost tried to take care of a farm in the state of New Hampshire. He was not a successful farmer. And he continued to write poetry. He said that until 1930, he earned only about ten dollars a year from writing.
In 1912, he decided to try to make a new start. He took his family to Britain. The cost of living was low. In Britain, Frost found a publisher for his first book of poems. The book was called A Boy’s Will. When it appeared in 1913, Frost received high praise from British readers. Praise was something he had not received in his own country.
Ezra Pound, another American poet living in Britain, read the poems and liked them very much. He wrote a magazine article about Frost. He also helped get Frost’s second book of poems published in America. That book was called North of Boston.
【小題1】The followings are writers EXCEPT __________.
| A．Robert Edward Lee | B．Robert Lee Frost |
| C．Ernest Hemingway | D．Ezra Pound |
| A．he had great influence on Frost’s poetry and life |
| B．Frost’s poetry style was the same as Hemingway’s |

Most of my earliest childhood memories are of the beach — in the hot sun, building sandcastles, burying Dad in the sand.
Now the coast has a pleasant and relaxing attraction beyond words. I look forward to a windy cliff-top walk or a rainy day rock-picking just as much as those rare moments when I get to a short sleep in the sun. But there’s nothing more pleasurable than turning up at a beach to find it deserted.
These are my favourite secret beaches — ones either not well known or take a bit of effort to get to. Most of those listed scored highly in the Marine Conservation Society Good Beach Guide 2009; the others are too secret even for them.
Sennen Clove is just a mile northeast of Land’s End, the westernmost point of mainland England. It’s a beautiful spot, with white sands, deep green sea and amazing sunsets over the Isles (群島) of Scilly, 28 miles away.
The west-facing beach is popular with surfers, with bigger waves and winds often found at the Gwenver end. There’s a beach restaurant with good views of the bay and the sunsets.
The smallest of Isles of Scilly, Bryher is a mile long, half a mile wide — and a natural wilderness of unbelievable scenery. Walk along the narrow sandy roads to the eastern seaboard and you come to two quiet beaches.
Green Bay has views over to the palm trees of Tresco’s Abbey Gardens, and a little further south is Rushy Bay, a beautiful beach facing the deserted island of Samson.
On Bryher, farm shops sell locally grown produce, and they trust you to leave the money in the pot. It’s that kind of place.
1.The best title for this passage is ________.
A. The Beautiful British Isles
B. Secret Beaches on the British Isles
C. The Most Pleasurable Place in Britain
D. My Experience of Searching Beaches
2.According to the passage, which of the following is TRUE?
A. The author is a tourist guide in a tourist agency.
B. The author likes walking on a rainy cliff-top most.
C. The author wrote the article to advertise for the beaches.
D. The author loves beaches that are not known to most people.
3.Which of the following maps can correctly describe the geography position?
(LE=Land’s End SC=Sennen Cove IS=the Isles of Scilly)
4.In the author’s view, farmers on Bryher are ________.
A. sincere B. selfish C. courageous D. mean
