Read the article and select the best answer. Article: Officials say the islands of Tokelau in the South Pacific Ocean have become the world's first territory totally powered by the sun.The move is expected to save money and ease the environmental burden of depending on imported fossil fuels. Tokelau's three main atolls ,or islands,now have enough solar capacity to meet all of their electricity needs.Until now.Tokelau has been 100%dependent on diesel for producing electricity.That has burdened the country with heavy economic and environmental costs. The three atolls of Tokelau are about halfway between New Zealand and Hawaii and are administered by New Zealand. Each atoll received its own solar power grid system.New Zealand officials estimated the cost of the project to build the three solar grids at around seven million dollars.The last of the grids has been completed. It is estimated that oil imports make up to 30%of national income in some parts of the Pacific.The move to solar power could save Tokelau about one million dollars a year.Tokelau will now be able to spend more on social programs to help its citizens. Other South Pacific islands are attempting similar projects.The island nations of Samoa and Tuvalu are aiming to get all of their electricity from renewable sources by 2020.The Cook Islands plans to start moving to solar panels and wind turbines.And most houses in the South Pacific groups of islands will begin to use solar water heaters. East Timor's government has promised that no households in the capital,Dili,would be using firewood for cooking by 2015.It also says 50%of the country's electricity will come from renewable sources by the end of the decade. New Zealand Foreign Affairs Minister Murray McCully says the country will hold a Pacific energy summit in March this year.He said the meeting would build on the success of clean and affordable energy solutions for Tokelau,Tonga,and the Cook Islands. Question: What can we learn from the text? Options: A: Some houses in Tokelau still lack solar capacity. B: Tokelau has partly depended on fuel electricity. C: Tokelau doesn't use imported diesel to produce electricity now. D: Not every atoll has its own solar power grid system in Tokelau.

Read the article and select the best answer. Article: A study found that young people have a stronger and more unpleasant scent than the elderly,while elderly people's smell was the most distinctive,less intense and unpleasant. Researchers said the change in our smell is driven by the chemicals we release through our glands and the bacteria on our skin. To test whether or not it really exists,scientists collected a series of samples from three groups of 12 to 16 donors,aged 20 to 30,45 to 55 and 75 to 95.Volunteers wore special T-shirts fitted with underarm pads as they slept for five nights,after which the pads were cut up and put in glass jars. A separate group of 41 people aged 20 to 30 was then asked to smell two jars at a time and asked which group of the donors was older,as well as rating how strong and unpleasant each smell was. When asked to specify whether a particular sample was from a young,middle aged or old person,they were much more successful at identifying older people. Despite being the most distinctive,the older people's smell was also rated as being obviously less intense and less unpleasant than those from the other groups. Researchers said their findings appeared to contradict people's negative ideas about the old person's smell but admitted other factors,like smelly breath or skin,could be to blame for its bad reputation. "Similar to other animals,humans can give off body scents that allow us to identify biological age,avoid sick individuals and pick a suitable partner. Elderly people have a distinctive scent that younger people consider to be not very unpleasant. This was surprising given the popular conception of old age scent as smelly. However,it's possible that other sources of body scents,such as skin or breath,may have different qualities," said Dr Johan Lundstrom,who led the study. Question: What is the author's purpose in writing this passage? Options: A: To tell old people how to remove their terrible scent. B: To prove that people often hold wrong ideas. C: To show how researchers carried out their study about the scent. D: To report the findings of a study about people's scent.

Read the article and select the best answer. Article: Ernest Hemingway was born in Oak Park, Illinois, on July 21st, 1899. Influenced by his father, he enjoyed camping, fishing and hunting at his early age. In 1917, after graduation from high school, Hemingway began his writing career with The Kansas City Star. And then, after being rejected for army service in World War I because of poor vision, he volunteered to serve as a driver for an American ambulance unit in France. In 1918, he transferred to duty on the Italian front, where he was seriously wounded in an explosion. After his recovery, he returned home. He worked for The Toronto star, covered the Greco-Turkish war as a foreign reporter, and then returned to Paris, which was a city full of intellectual life, creativity, and genius after the war. In Paris, where he accomplished a revolution in literary style and language, his first book, Three Stories and Ten Poems, appeared in 1923, and was followed by a short story collection In Our Time, which marked his entry to American literature in 1925. Hemingway's status as a remarkable writer of his time was confirmed with the publication of A Farewell to Arms in 1929. The novel represented a farewell both for war and for love. In 1937, he became a foreign reporter covering the Spanish Civil war. Three years later, he published For Whom the Bell Tolls. Set in Spain during the Civil war, the novel restated his view of love found and lost and described the tough spirit of the common people. In 1912, the same judgment was reflected in his portrait of fisherman, Santiago, with an _ spirit in defeat, in The Old Man and the Sea, which was awarded the Pulitzer Prize in 1953. Hemingway won the Nobel Prize in Literature in 1954. With one of the most important influences on the development of the American short story and novel, Hemingway has seized the imagination of the American public like no other twentieth-century author. He died by suicide, in Ketchum, Idaho, in 1961. Question: The publication of _ proved Hemingway one of the greatest literary lights of the 20th century. Options: A: Three Stories and Ten Poems B: A Farewell to Arms C: The Old Man and the Sea D: In Our Time
