Native to America, the cane toad was introduced to northern Queensland 70 years ago to control sugarcane beetles . The toads failed in that duty but spread across prefix = st1 /Queenslandand into neighboring northern area. Now it calmly invades the states of Western Australia and New South Wales (NSW). NSW wildlife experts fear _ --which have poisonous backs that kill hungry predators, --will have a terrible effect on native animals. Those fears may be about to be realized. Australia's leading government research body, the Commonwealth Science and Industry Research organization (CSIRO), forecasts a rise in average temperatures that will make NSW ideal living place for the cane toad. Tony Robinson, head of CSIRO's Wildlife,Pests,and Diseases Program, said climate change is increasing the amount of suitable living place for the toad. "With climate change, the cane toads might go down as far as Sydney and some areas of Western Australia," Robinson said. Recent estimates put the pace of the toad's westward march at nearly 17 miles(27 kilometers)a year and slightly slower from north to south. More southerly cities, such as Melbourne and Adelaide, would likely remain too cold and dry to ever suit the toads, Robinson noted, but Perthcould expect cane toads in five years' time. Sydney could see their arrival in the next 20 years. Robinson said there is no 0ne method that will keep the toads under control. The cane toads already cover at least half of Queenslandand most of the northern country the toads are believed to number in the billions. A Venezuelan virus was tried in the 1990s but had to be given up after it was found to also kill native frog species. Scientists and governmental bodies believe a national approach is needed. The main threat the toads cause to species such as dingos, quolls, goannas, and crocodiles is the poison contained in glands on each of the frogs' shoulders. The poison sprays out when the toads are threatened or handled roughly. The poison is made up of 14 different chemicals.... According to the passage, which of the following is true about the cane toads? A) The cane toads are strong enough to kill dingos, quolls or even crocodiles. B) With 14 different kinds of poisons in its body, a cane toad always wins the hunt for food. C) The cane toad was brought to Australiato kill pests fromAmerica70 years ago. D) The toads move westward and northward because there is plenty of food there.

Ask most people how they define the American Dream and chances are they'll say, "Success." The dream of individual opportunity has been home in American since Europeans discovered a "new world" in the Western Hemisphere. Early immigrants like Hector St. Jean de Crevecoeur praised highly the freedom and opportunity to be found in this new land. His glowing descriptions of a classless society where anyone could attain success through honesty and hard work fired the imaginations of many European readers: in Letters from an American Farmer (1782) he wrote. "We are all excited at the spirit of an industry which is unfettered and unrestrained, because each person works for himself ... We have no princes, for whom we toil ,starve, and bleed: we are the most perfect society now existing in the world." The promise of a land where "the rewards of a man's industry follow with equal steps the progress of his labor" drew poor immigrants from Europe and fueled national expansion into the western territories. Our national mythology is full of illustration of the American success story. There's Benjamin Franklin, the very model of the self-educated, self-made man, who rose from modest origins to become a well-known scientist, philosopher, and statesman. In the nineteenth century, Horatio Alger, a writer of fiction for young boys, became American's best-selling author with rags-to-riches tales. The notion of success haunts us: we spend million every year reading about the rich and famous, learning how to "make a fortune in real estate with no money down," and "dressing for success." The myth of success has even invaded our personal relationships: today it's as important to be "successful" in marriage or parenthoods as it is to come out on top in business. But dreams easily turn into nightmares. Every American who hopes to "make it" also knows the fear of failure, because the myth of success inevitably implies comparison between the haves and the have-nots, the stars and the anonymous crowd. Under pressure of the myth, we... By saying "the rewards of a man's industry follow with equal steps the progress of his labor" (Line 10, Para. 1), the author means _ . A) the more diligent one is, the bigger his returns B) laborious work ensures the growth of an industry C) a man's business should be developed step by step D) a company's success depends on its employees' hard work

Ques: About l,500 years ago the Japanese imported many aspects of Chinese culture :the writing system, political institutions, and perhaps the most important, Buddhism. Buddhist priests were expected to eat only vegetables, and tofu, made from the soybean, was a very important food in their diet.When Buddhism was introduced from China, tofu was also brought to Japan. Tofu developed in different ways in China and Japan.While the Chinese often changed the taste of tofu by mixing it with strongly - flavored vegetables or meat, the Japanese preferred to eat it using only a simple sauce. Even now, traditional Japanese cooking preserves the original delicacy of tofu, though the way it is served may change from season to season. In summer, for example, it is simply served cold, while in winter it is often eaten as part of a hot dish. The soybean was introduced to the West in the 18th century, but little interest was taken in it. Only scientists recognized its high food value.During the Second World War, when meat was in short supply, the US government encouraged the American people to eat soybean products.However, they never became very popular and, after the war, interest in them dropped off as the supply of meat became plentiful again. In recent years, people in the West have become increasingly aware of the dangers of eating too much animal fat, and as a result, they have turned more and more to soybean products. This is mainly because the soybean provides almost the same food value as meat, and in addition it is a lot more healthful. Much of the margarine ,salad oil and cooking oil in daily use is now produced from soybean oil.Tofu, a representative soybean product and originally one of the main foods in the diet of Chinese priests, is considered to be one of the healthiest foods available to man. Tofu came to Japan together with Buddhism because _ . A) Buddhist priests ate tofu rather than vegetables B) it was a very important food in the diet of Buddhist priests C) the religion came to Japan together with political institutions D) the religion was the most important aspect of Chinese culture
