Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too. There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families. In the next few hundred years we can expect language to _ . A) stay exactly the same B) change a great deal C) change only a little D) ask more words and drop some grammar
B

ScienceDaily (July 5, 2009) -- Researchers from the University of Haifa-Oranim have managed to make out the "self-irrigating" mechanism of the desert rhubarb , which enables it to harvest 16 times the amount of water collected by other plants in the Negev Desert. This is the first example of a self-irrigating plant worldwide. The desert rhubarb grows in the mountains of Israel's Negev desert, where average rainfall is particularly low (75 mm per year). Unlike most of the other desert plant species, which have small leaves so as to reduce water loss, this plant is unique in that its leaves are particularly large; each plant's rosette of one to four leaves reaches a total diameter of up to one meter. Prof. Simcha Lev-Yadun, Prof. Gidi Ne'eman and Prof. Gadi Katzir came across this unique plant while studying the field area with students of the Department of Science Education-Biology of the University of Haifa-Oranim, and noticed that its waxy leaves are unusually large. They observed an exceptionally ridged structure on each leaf. The scientists explained that these deep and wide depressions in the leaves create a "channeling" mountain-like system by which the rain water is channeled toward the ground surrounding the plant's deep root. Other desert plants simply absorb the rain water that goes through the ground in its immediate surroundings. The desert rhubarb is able to harvest quantities of water that are 16 times the amount of water harvested by the small-leafed plants of the Negev desert region. When the research team watered the plant artificially, they observed how the water flows along the course of the leave's depressions to the ground surrounding the plant's single root and then goes through the ground to a depth of 10 cm or more. Under the experimental conditions, water goes through the ground only as deep as 1 cm. "We know of no other plant in the deserts of the world that functions in this manner," the researchers concluded. What is the best title for the passage? A) How plants' "self-irrigating" mechanism works B) How plants growing in the desert survive C) The desert plants growing in the Negev Desert D) The world's first "self-watering" plant discovered

Ques: The shocking disappearance of Malaysia Airlines Flight MH370 has captured the attention of millions around the world as the search for the airplane and its passengers and crew continues. What happened to the flight's 239 passengers and crew after the plane left Kuala Lumpur on Saturday? It is becoming an increasingly desperate question as the days pass. But it's hardly the first mystery of its kind. Here are some half-solved and unsolved airline mysteries that kept investigators clueless for years. Air France Flight 447: An Airbus A330 flight from Rio de Janeiro to Paris _ into the Atlantic Ocean in 2009, killing all 228 passengers and crew on board. But it took a full five days for search and rescue teams to find the wreck and another three years for investigators to report that ice crystals had caused the autopilot to disconnect. The bodies of 74 passengers remain unrecovered. Amelia Earhart: Ace pilot Amelia Earhart disappeared in her twin-engine monoplane Electra over the Pacific Ocean in 1937 in an attempt to circumnavigate the globe. No trace of her plane was ever found even after a multi-million dollar search effort, and Earhart was officially declared dead in 1939. Flying Tiger Line Flight 739: A U.S. military flight left Guam in 1962 with more 90 personnel headed for the Philippines, but it never arrived. The pilots never issued a distress call, and 1,300 people involved in the U.S. military search never found any trace of wreckage. British South American Airways: It took more than 50 years to find any trace of the 11 people aboard a 1947 flight that disappeared in the Andes Mountains. A pair of Argentineans rock climbers discovered engine wreckage in the Andes in 1998, and an army expedition later found human remains as well. Uruguayan Air Force Flight 571: A flight headed to Santiago, Chile carrying 45 passengers and crew crashed into the Andes Mountains in poor weather in 1972, killing twelve people. In the meantime, eight were killed in an avalanche that hit the plane's wreckage where they... What can we learn from Uruguayan Air Force Flight 571? _ . A) 12 people were lost until now. B) 25 people were rescued instantly. C) The rest who stayed alive killed 8 people. D) 8 were killed by a fall of a large mass of snow down a mountainside.
Ans: D
Ques:Unconventional in every way, Edward Estlin Cummings made striking use of grammar. His arts were poetry, painting, and drama, and in all of them he was an experimenter. The poetry -- for which he is best remembered -- was marked by strange combinations of words and expressions and produced in very strange print. The unusual techniques that Cummings used served to present his ideas more forcefully and effectively than would have been the case with more ordinary styles. Cummings was born in Cambridge, Massachusetts, on Oct. 14, 1894. He graduated from Harvard College in 1915 and received a master's degree in 1916. During World War I he served as an ambulance driver in France. He spent six months in prison because of his friendship with another American who had supposedly criticized the countries that fought against Germany in the First World War. This experience increased his distrust of all officialdom , a distrust that showed itself in many of his later poems as well as in his first book, "The Enormous Room", published in 1922. Between the two world wars Cummings divided his time between Paris and New York City. His first book of poetry was "Tulips and Chimneys" (1923). The poems in the book were collected in "Complete Poems" (1968). The strangeness of his style was criticized by some, but others found it meaningful. Among Cummings' plays were "Him", first performed in 1927, and "Tom" (1935), a work based on "Uncle Tom's Cabin". An experimental prose book, "Eimi" (1933), recorded a 36-day visit to the Soviet Union. Cummings died at his home in North Conway, N.H., on Sept. 3, 1962. He was the second most widely read poet in the United States, after Robert Frost. He was buried in Forest Hills Cemetery in Boston, Massachusetts. The text is mainly about Edward Estlin Cummings' _ . A) creative ideas B) great artistic abilities C) life and works D) influence on American literature
