    The Ebro Delta, in Spain, famous as a battleground during the Spanish Ci War, is now the setting for a different contest, one that is making rice farmers fight against two enemies: the rice - eating giant apple snail, and rising sea levels. What happens here will have a bearing on the future of European rice production and the overall health of southern European wetlands.

Located on the Mediterranean, just two hours south of Barcelona, the Ebro Delta produces 120 million kilograms of rice a year, making it one of the continent most important rice - growing areas. As the sea creeps into these fresh-watch marshes, however, rising salinity(盐度)is hurting rice production. At the same time, this sea - water also kills off the greedy giant apple snail, an introduced pet species that fees on young rice plants. The most promising strategy has become the play one enemy off against the other.

The battle is currently being waged on land, in greenhouses at the University of Barcelona. Scientists working under the banner “Project Neurice” are seeking varieties of rice that can withstand the increasing salinity without losing the absorbency that makes European rice ideal for traditional Spanish and Italian dishes.

“ The project has two sides,” says Xavier Serrat, Neurice project manager and researcher at the University of Barcelona. “The short -term fight against the snail, and a mid-to long term fight against climate change. But the snail has given the project greater emergency.”

Originally from South America, the snails were accidentally introduced into the Ebro Delta by Global Aquatic Technologies, a company that raised the snails for fresh-water aquariums(水族馆)but failed to prevent their escape. For now, the giant apple snail’s presence in Europe is limited to the Ebro Delta. But the snail continues its march to new territory, says Serrat.

“The question is not whether it will reach other rice - growing areas of Europe, but when.”

Over the next year and a half investigators will test the various strains of salt - tolerant rice they’ve bred. In 2018, farmers will plant the varieties with the most promise in the Ebro Delta and Europe’s other two main rice- growing regions along the Po in Italy, and France’s Rhone. A season in the field will help determine which, if any of the varieties are ready for commercialization.

As an EU - funded effort, the search for salt - tolerant varieties of rice is taking place in all three countries. Each team is crossbreeding a local European short - grain rice with a long - grain Asian variety that carries the salt resistant gene. The scientists are breeding successive generations to arrive at varieties that in corporate salt tolerance but retain about 97 percent of the European rice genome(基因组).

1.Why does the author mention the Spanish Civil War at the beginning of the passage?

A.Because it significantly influences the lives of Spanish rice farmers.

B.Because it is extremely important in the records of Spanish history.

C.Because rice farmers there are engaged in another kind of battle of similar importance.

D.Because rice farmers there are experiencing the hardships of wartime.

2.What may be the most effective strategy for rice farmers to employ in fighting their enemies?

A.Striking the weaker enemy first.

B.Killing two birds with one stone.

C.Eliminating the enemy one by one.

D.Using one enemy to fight against the other.

3.What does the Neurice project manager say about the giant apple snail?

A.It can survive only on southern European wetlands.

B.It will invade other rice - growing regions of Europe.

C.It multiplies at a speed beyond human imagination.

D.It was introduced into the rice fields on purpose.

4.What is the ultimate goal of the EU - funded program?

A.Cultivating ideal salt resistant rice varieties.

B.Increasing the absorbency of the Spanish rice.

C.Introducing Spanish rice to the rest of Europe.

D.Popularizing the rice crossbreeding technology.

 

1.C 2.D 3.B 4.A 【解析】 这是一篇说明文。主要说明了西班牙埃布罗三角洲如今正被吃水稻的巨型苹果蜗牛和不断上升的海平面所威胁。文章解释了背后的原因,以及科学家们正在寻找能够承受不断升高的盐度、同时又不丧失吸收能力的大米品种,同时预计巨型苹果蜗牛未来会继续入侵欧洲其他水稻种植区。 1.推理判断题。根据第一段The Ebro Delta, in Spain, famous as a battleground during the Spanish Ci War, is now the setting for a different contest, one that is making rice farmers fight against two enemies: the rice - eating giant apple snail, and rising sea levels.(西班牙的埃布罗三角洲曾是西班牙Ci战争期间著名的战场,现在这里又成了另一场竞赛的场地,在这场竞赛中稻农们与两个敌人作战:吃水稻的巨型苹果蜗牛和不断上升的海平面。)可知作者在文章的开头提到了西班牙内战,是因为那里的稻农正在进行另一种同样重要的战争。故选C。 2.细节理解题。根据第二段中The most promising strategy has become the play one enemy off against the other.(最有希望的策略是一个敌人对付另一个敌人。)可知用一个敌人对付另一个敌人可能是稻农对付敌人最有效的策略。故选D。 3.推理判断题。根据倒数第四段For now, the giant apple snail’s presence in Europe is limited to the Ebro Delta. But the snail continues its march to new territory, says Serrat.(目前,巨型苹果蜗牛在欧洲的存在仅限于埃布罗三角洲。但Serrat说,蜗牛继续向新的领域进军。)可知Neurice项目经理表示,巨型苹果蜗牛将入侵欧洲其他水稻种植区。故选B。 4.细节理解题。根据最后一段第一句As an EU - funded effort, the search for salt - tolerant varieties of rice is taking place in all three countries.(作为欧盟资助的一项努力,这三个国家都在寻找耐盐水稻品种。)可知欧盟资助项目的最终目标是培育理想的耐盐水稻品种。故选A。

Procrastination - a Virtue When It Comes to Creativity?

Psychologist Adam Grant, from the University of Pennsylvania in Philadelphia, argues that people who “put off” solving a task for a little while - thus engaging in moderate procrastination -- are often able to come up with 1. (original) ideas about how to solve that task than people who get started on their work right away.

Grant makes this argument in the book Originals: How Non-conformists Change the World and reiterates it in a popular TED talk 2. he says that “procrastination is a vice when it comes to productivity, but it can be a virtue when it comes to creativity.” This point of view seems 3. (find) some support in existing studies that indicate a correlation between creativity and “putting things off.”

Grant explains that the link between moderate procrastination and originality likely 4. (exist) because when we actively put off a task for a while, our preoccupation with the task itself does not disappear. Instead, the unfinished work “runs in the background” of our brains, 5. (buy) us time to find innovative solutions.

One study 6. (publish) in Personality and Individual Differences in 2017 also found a link between creative ideation (coming up with creative ideas) and active procrastination. It suggested that among 853 undergraduates at Chinese universities, “active procrastinators” may be more prone to creativity.

Boredom 7. have something to do with this boost in creative thinking. Older research from the University of Florida in Gainesville suggests that people who procrastinate may be more prone to boredom than their peers.

And while boredom itself is a concept that sometimes has negative connotations, studies 8. (show) that allowing ourselves to feel bored for a while can boost our creative abilities. The researchers explain that this may be because when we are bored, we allow our minds to wander, thus “training” our imaginations.

Finally, 9. putting off a task forever out of fear and self-doubt may be paralyzing and unhelpful, a little bit of “directed” procrastination will likely not be harmful and may allow us to assess the task at hand more imaginatively.

And for some of us, that pressure of looking a deadline straight in the eye can be just 10. we need to keep us on our toes. As Calvin, one of the main characters in the comic strips Calvin and Hobbes, once said : “You can’t just turn on creativity like a faucet. You have to be in the right mood,” and that mood is “last - minute panic.”
