British scientists are breeding a new generation of rice plants that will be able to grow. in soil containing 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 Biological Sciences Research Council, to establish which genes enable some plants to survive salty conditions. The aim is to breed this capability into crops, starting with rice.
It is estimated that each year more than 10 million hectares (公顷) of agricultural land are lost because salt gets into the soil and stunts(防碍生长) plants. The problem is caused by several factors. In the tropics, mangroves that create swamps (沼泽) 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 (渗透) 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 resulting 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.

| Café en Seine The wildly luxury (奢华) new art style of this huge bar has been a huge hit since it first opened in 1995, and while it may not be the “in” place it once was, it is still very popular with the after-work crowd and out-of-towners. Maybe it’s the glass frames, or the real 12m-high trees; but most likely it’s the beautiful people supporting the wood-and-marble bar. Good for: decoration, cocktails, amazing food and service Address: 40 Dawson St Transport: all city centre Phone: 01 677 4369 |
| Gravediggers (aka Kavanagh’s) The gravediggers from the neighboring Glasnevin Cemetery had a secret serving hatch (舱口) so that they could drink on the job – therefore the pub’s nickname. Founded in 1833 by one John Kavanagh and still in the family, this pub is one of the best in Ireland, almost unchanged in 150 years. In summer time the green of the square is full of drinkers bathing in the sun, while inside the hardened locals ensure that never a hint of sunshine disturbs some of the best Guinness in town. An absolute classic. Good for: Guinness, traditional pub, pub food Address: 1 Prospect Sq Glasnevin Transport: 13 from city centre Phone: 830 7978 |
| Davy Byrne’s James Joyce, an Irish author and a poet (1882-1941), would hardly recognize the bar that Leopold Bloom rushed into for a gorgonzola sandwich and a glass of wine in Ulysses. It doesn’t stop Davy Byrne’s from making the most of its Joyce’s connections, even though today's version is strictly for out-of-towners and the rugby crowd. Good for: socializing with the locals, tasty Irish food, watching TV Address: 21 Duke St Transport: all city centre Website: www.davybyrnes.com Phone: 01 677 5217 |

We regularly hear how important consumer spending is for the economy. The story goes like this：the more consumers spend，the more money circulates in the economy, which contributes to healthy job growth and profits. Keynes, a British economist，went as far as to say that individuals saving their money may actually be hurting the economy. Sounds troubling, doesn’t it?
Fear not. You aren’t actually hurting anyone else by saving money. Strong economic growth only comes from one place：savings. Not consumption. In fact，economic activity should not be mistaken for economic growth. For example，somebody takes their money, walks into a store, and purchases goods. The store increases its revenue.
But what happens to all of those goods and services that people have chosen not to consume by saving their money? Simple：Other people are allowed to consume them. Think of it this way：When you lend out your savings, you are actually saying，“Here, I am not going to consume right now, so why don’t you?” Banks simply play the middleman：they collect lots of people’s savings and then lend out lots of funds.
It takes an unbelievable amount of goods and services to construct a building. It takes food, shelter, and entertainment for all of the workers, as well. Without savings，it is quite impossible to finance such a construction. The coordination(协调)between savings and consumption is a necessary basis for sound economic growth. This coordination is also why consumer lending (say , to borrow a big sum of money to buy a car) is not productive，in a strict sense. It doesn’t increase the net (净的) amount of wealth of an economy. Those savings could have been used to construct, say, factory equipment.
None of this means consumption and spending are “bad” things. They simply do not make us wealthier. After all, the final goal of production and savings is to consume. But to say that consumption is the engine of economic growth is to put the cart before the horse. Or, to rephrase: the consumption of wealth can never make you wealthier. Happier, perhaps. Wealthier, no.What is the author’s attitude towards Keynes’ theory?

In her new book, “The Smartest Kids in the World,” Amanda Ripley, an investigative journalist, tells the story of Tom, a high-school student from Gettysburg, Pennsylvania, who decides to spend his senior year in Warsaw, Poland. Poland is a surprising educational success story: in the past decade, the country raised students’ test scores from significantly below average to well above it. Polish kids have now outscored(超过……分数) American kids in math and science, even though Poland spends, on average, less than half as much per student as the United States does. One of the most striking differences between the high school Tom attended in Gettysburg and the one he ends up at in Warsaw is that the latter has no football team, or, for that matter, teams of any kind.
That American high schools lavish more time and money on sports than on math is an old complaint. This is not a matter of how any given student who plays sports does in school, but of the culture and its priorities. This December, when the latest Program for International Student Assessment(PISA) results are announced, it’s safe to predict that American high-school students will once again display their limited skills in math and reading, outscored not just by students in Poland but also by students in places like South Korea, Belgium, the Netherlands, Finland, Singapore, and Japan. Meanwhile, they will have played some very exciting football games, which will have been breathlessly written up in their hometown papers.
Why does this situation continue? Well, for one thing, kids like it. And for another, according to Ripley, parents seem to like the arrangement, too. She describes a tour she took of a school in Washington D.C., which costs thirty thousand dollars a year. The tour leader—a mother with three children in the school—was asked about the school’s flaws(暇疵). When she said that the math program was weak, none of the parents taking the tour reacted. When she said that the football program was weak, the parents suddenly became concerned. “Really?” one of them asked worriedly, “What do you mean?”
One of the ironies(讽刺) of the situation is that sports reveal what is possible. American kids’ performance on the field shows just how well they can do when expectations are high. It’s too bad that their test scores show the same thing.Tom decides to spend his senior year in Poland because _______.
| A．there are striking differences between the 2 countries |
| B．Polish kids are better at learning |

Four years ago my sweet mom went to be with her Lord. She did it her way.
I got the call at work, and I headed home quickly. Mom and Dad lived on a small farm that they had owned since I was seven. I hated going there every weekend. There was nothing for a young girl to do but watch the one station on the old TV set, if the weather allowed reception.
My mom, on the other hand, loved the peace and quiet of the land. The place was rustic, with no indoor plumbing or heat. We had a big wood stove in the kitchen that did its best to heat the little farmhouse, but it always seemed cold and too quiet to me.
In the evenings, my mom and I would sit for hours singing in the little kitchen. I sang the melody and Mom harmonized. Her favorite song was "Moon River" and we sang it over and over. Mom told me stories about how when I was a little girl, I could sing before I could talk.
As time passed, I had my own children and went to visit them every week or two. The kids loved the farm and the tractor rides with my dad. Me, well, I still hated the silence of the farm. While my mom loved to sit at her kitchen table and look out at her garden and flowers and retell all the old stories, I missed the hustle and bustle（喧闹）of my life at home. But I sat there listening quietly as she reminisced.
Now, I sat back in the silence and the silence was deafening so I finally leaned over to turn on an old radio. Music always comforted me.
My heart skipped a beat. "Moon River" was playing on the radio. I sat there stunned, with a tear running down my cheek, as I listened to every familiar note.From the first paragraph, we know that the writer’s mother ________.
| A．passed away four years ago |

As we have seen, the focus of medical care in our society has been shifting from curing disease to preventing disease-especially in terms of changing our many unhealthy behavior, such as poor eating habits, smoking, and failure to exercise. The line of thought involved in this shift can go further. Imagine a person who is about the right weight, but does not eat very nutritious
foods, who feels OK but exercises only occasionally, who goes to work every day, but is not an outstanding worker, who drinks a few beers at home most nights but does not drive while drunk, and who has no chest pains or abnormal blood counts, but sleeps a lot and often feels tired. This person is not ill. He may not even be at risk for any particular disease. But we can imagine that this person could be a lot healthier.
The field of medicine has not traditionally distinguished between someone who is merely "not ill" and someone who is in excellent health and pays attention to the body’。special needs. Both types have simply been called "well". In recent years, however, some health specialists have begun to apply the terms "well" and "wellness" only to those who are actively striving to maintain and improve their health. People who are well are concerned with nutrition and exercise, and they make a point of monitoring their body's condition. Most important, perhaps, people who are well take active responsibility for all matters related to their health. Even people who have a physical disease or handicap（缺陷）may be "well", in this new sense, if they make an effort to maintain the best possible health they can in the face of their physical limitations. "Wellness" may perhaps best be viewed not as a state that people can achieve, but as an ideal that people can strive for.
People who are well are likely to be better able to resist disease and to fight disease when it strikes. And by focusing attention on healthy ways of living, the concept of wellness can have a beneficial impact on the ways in which people face the challenges of daily life.Today medical care is placing more stress on＿＿．
| A．keeping people in a healthy physical condition |
| B．monitoring patients’ body functions |
| C．removing people’s bad living habits |
| D．ensuring people’s psychological well-being |
In the first paragraph, people are reminded that＿＿．
| A．good health is more than not being ill |
| B．drinking, even if not to excess, could be harmful |
| C．regular health checks are essential to keeping fit |
| D．prevention is more difficult than cure |
Traditionally, a person is considered "well” if he＿＿．
| A．does not have any unhealthy living habits |
| B．does not have any physical handicaps |
| C．is able to handle his daily routines |
| D．is free from any kind of disease |
According to the author, the true meaning of "wellness" is for people to＿＿．
| A．best satisfy their body’s special needs |
| B．strive to maintain the best possible health |
| C．meet the strictest standards of bodily health |
| D．keep a proper balance between work and leisure |
