e setting for a different contest, one that is pitting rice farmers 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’s most important rice-growing areas. As the sea creeps into these fresh-water marshes, however, rising salinity(盐分)is hampering rice production. At the same time, this sea-water also kills off the greedy giant apple snail, an introduced pest that feeds on young rice plants. The most promising strategy has become to harness one foe 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 urgency.”

Originally from South America, the snails were accidentally introduced into the Ebro Delta by Global Aquatic Tecnologies, 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 if 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 Rh？ne. 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 incorporate salt tolerance but retain about 97 percent of the European rice genome(基因组). Why does the author mention the Spanish Civil War at the beginning of the passage？

A.It had great impact on the life of Spanish rice farmers.

B.It is of great significance in the records of Spanish history.

C.Rice farmers in the Ebro Delta are waging a battle of similar importance.

D.Rice farmers in the Ebro Delta are experiencing as hard a time as in the war.

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 evil to combat the other

What do we learn about “Project Neurice”？A.Its goals will have to be realized at a cost.

B.It aims to increase the yield of Spanish rice.

C.Its immediate priority is to bring the pest under control.

D.It tries to kill the snails with the help of climate change.

What does 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.

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.

young nation established in an ancient land. Its development represents a triumph(胜利)over remoteness and a harsh landscape.

It is generally accepted that Australia's original inhabitants, the aboriginal(土著的)people, have lived on the continent for 40,000 to 60,000 years. They were also its sole(唯一的)human inhabitants until two centuries ago. Indonesian traders probably visited Australia's northwest but it was unknown to the rest of the world until the 1600s. A huge south land appeared on maps before 200 AD but its existence was not confirmed until the 17th century when Portuguese, Spanish and Dutch merchants ventured into Asia.

The first European settlement of the continent--by the British--began in 1788, on the site now occupied by Sydney, Australia's largest city. There were then about 1500 Europeans and an estimated 300,000 aboriginal people in Australia. The population has reached 2.25 million by 1881, 5.41 million by 1921 and 7.4 million by the end of World War II(1945). It increased sharply, partly because of a large postwar immigration program, and reached more than 17 million in 1991, despite a decline that began in the 1970s in the natural increase and net immigration. The rate of population increase in the 40 years after world war II, about two percent, has halved.

Australia is one of the most urbanized countries in the world, with about 70 percent of the population living in the 10 largest cities. Australians have a high standard of living by world standards. The flag of Australia is the only one to fly over a whole continent in the world. The small Union Jack represents the historical link with Britain, the largest star has six points for each of the states and one point for the territories, and the small stars form. the Southern Cross - a prominent of the southern hemisphere night sky.

The American victory in the Revolutionary War united 13 of the English-speaking settlements into the largest and most powerful political unit in the territory , even though those first 13 states hugging the eastern coast seem small compared with the country' s eventual size. As a result of the Revolution ,approximately 71 , 500 people out of a population of some 2. 5 million fled the new United States. Some were Loyalists - political or economic refugees whose loyalties to Great Britain remained strong; others were blacks seeking refuge from slavery. Immigration and the commercial slave trade after the war quickly restored the population to its former level. The Revolution also opened up the area west of the Appalachian Mountains to settlement , as fur traders and farmers were no longer confined by British settlement restrictions. Pioneering citizens , immigrants , and slaves moved west , displacing Native Americans who had hoped to preserve their cultures undisturbed by the expanding United States.

The 17th and 18th centuries saw a growing importation of Africans into North America. After 1808 U. S. law forbade the importation of slaves from abroad , although some smuggling of slaves continued. Few people from Africa chose to come to the United States voluntarily (the free African population was small) because they were considered second-class citizens , and confined largely to the northern states. Large numbers of Europeans migrated to the United States in the early national period , drawn by the promise of freedom , cheap land in the West , and jobs in the first factories of the emerging industrial age. The influx of Europeans , the end of the slave trade , and the ongoing wars removing Native Americans meant that some of the racial diversity of the population was diminishing. By the early decades of the 19th century , a greater proportion of Americans were of western European and Protestant heritage than at the time of the Revolution.

Over the course of the 19th century , the United States gradually absorbed the French colonists in the upper Midwest and in New Orleans , Louisiana; the Spanish and Russian colonists in the South , West ,and Northwest; and the territories of the Hawaiian people and other indigenous groups. Sometimes these territories were added by diplomacy , sometimes by brute force. European visitors were surprised at the diversity in nationalities and in religious and secular beliefs in early America , as well as the number of intermarriages between people of differing European heritages. There were also cross-racial births , sometimes voluntary and sometimes by force , but rarely within legal marriages. The population continued to grow through migration as well , driven in part by English , Irish , and German settlers who came in large numbers around 1848 to escape political repression and food shortages in Europe.
