Article: Parents are often amazed at how fast their child grows and develops. New research has determined that the ability to quantify may develop much sooner than most parents realize. Kristy vanMarle, professor of the University of Missouri, has determined that contrary to what previous studies have shown, infants are able to quantify substances --like sand or water--as early as 10 months. As long as the difference between the two substances is large enough, infants will choose the larger amount, especially when it comes to food. With the assistance of her team researchers, vanMarle tested the quantifying skills of babies by presenting them with two cups: one containing a small amount of food, and one containing a larger amount. Consistently, the babies chose the larger amount. "Several studies throughout the last 15 years have shown that infants are very good at telling how many objects they see; however, infants don't seem to count things like water or sand," vanMarle said. "What we're saying is that they can quantify substances; The infants can see how much food goes into each cup and compare that in their memories. They decide which amount is larger, and they almost always select the larger one." This information further refutes the long-held idea that babies "know nothing of the world," vanMarle said. "Since psychologists have begun studying infants with sensitive measures, we've discovered a lot of early abilities. I think for parents, it should be exciting to know that there's somebody there that has some fundamental and basic knowledge of the world, and that knowledge is guiding their development," vanMarle said. In the future, vanMarle says this kind of study could be linked to a child's progress in math-related skills, although programs marketed to increase those abilities, such as "Baby Einstein," still have mixed reviews when it comes to academic study.
Answer: through their natural abilities
Babies choose the larger amount of food _ .

Article: The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland. Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation. JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers." For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident. Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water. JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables." The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean. JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of _ . So the concentration of radioactivity in the seawater would still be quite low." Japan is the only country to have had atomic bombs dropped on it. That memory from World War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says. Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry. A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths. The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen. To get the latest updates, go to www.unsv.com.

Article: Many people have tried to simplify the spelling of English words. Unlike other languages , English sometimes spells the same sounds in very different ways . For example , there is "light "but" white", "loan "but "phone" ,and there are at least seven different ways of pronouncing "ough": "though", "through ","bough". "cough" "enough ", "ought" and "thorough ". The American President Theodore Roosevelt almost succeeded in simplifying English spelling .In 1906, Andrew Carnegie started the Simplified Spelling Board .He was one of the richest men in the United States of America .The board's plan was to make the spelling of words nearer to the way they sound .For example , the word "though" would be spelt "tho" and "through "would become "thru". Other people on the board were Melvil Dewey , the head of the New York libraries , and Professor Brander Matthews of Columbia University . They explained their idea to President Roosevelt , who thought that it was indeed logical .He immediately asked the government printer to sue simplified spelling in all government letters . But people didn't like the change, even if it made life easier. So the new simpler spelling was not popular. More importantly, when the American politicians discussed the plan, they did not like it either. Because Roosevelt did not want to have any problems with the politicians, he changed his mind and told the printer to go back to the old way of spelling. Since then no one in any government has dared to simplify English spelling. However,people do simplify some words, mainly in advertisements. For example, we often see "tonite" instead of "tonight" and "thru" instead of "through".
Answer: sometimes the same sounds have different spellings.
Many people have tried to simplify English spelling because _ .
