1、AIs milk the best way to get calcium? A new report says it may not be.“Drink your milk. Its good for you!”Youve probably heard that many times, and its true. Milk contains calcium, which is a necessary nutrient for keeping bones and teeth healthy and strong. The U.S. government even requires milk as
2、 part of the National School Lunch Program, saying that students should drink one cup of fat-free or low-fat milk at each meal.Last Thursday, however, a group of doctors asked the government to remove milk from the lunch program. The Physicians Committee for Responsible Medicine (PCRM) says, “Milk i
3、s high in sugar, high in fat and high in animal protein,” all of which have negative effects on health. The PCRM says there are better and healthier ways to get calcium such as eating beans, broccoli, cereals and tofu. Orange juice and soymilk that have calcium added to them also supply the nutrient
4、. “One of the only reasons people talk about dairy, or promote it at all, is because it is going to help build strong bones,” says Dr. Neal Barnard, president of the PCRM. But milk may not be the best way to get the calcium your body needs.Of course, calcium is important for healthy bones and teeth,
5、 but there are other things that affect your bone strength, such as genes, how much vitamin D you take in and getting an hours worth of exercise every day.Some nutritionists disagree with the idea that milk isnt important. Keri Gans, a dietitian, says, “I think its irresponsible to take this beverag
6、e（饮料）that children enjoy, especially among those who are unable to meet their nutrient needs for the day, and remove it from the lunch line.”The U.S. government is studying the request of the PCRM, but a decision may be a long way off. Meanwhile, Marion Nestle, a professor at New York University, pu

As a child, his interests included hockey（曲棍球）, creative writing, art and music. Foxs acting talents began to emerge in his teens, and at eighteen he moved to Los Angeles. As he re
10、gistered with the Screen Actors Guild he realized that another actor had registered under the same name. To show respect for one of his favorite character actors of all time, Michael J.

From “Family Ties” Fox went on to star in several notable films, including the Back to the Future trilogy, The American President and Doc Hollywood.As Fox s fans know and love, he lives life no matter the challenge or opportunity.
12、In fact, his current real-life role may be the most inspiring part he has ever played. In 1998, Michael let the world know that he had Parkinsons disease. Showing the same commitment, drive and imagination we had come to love in his years on the large and small screens, he quickly emerged as a leadi
13、ng advocate and spokesperson to increase awareness of Parkinsons disease and funding for critically needed research toward a cure. The Michael J. Fox Foundation he established in 2000 is dedicated to finding a cure for Parkinsons disease by strategically prioritizing（优先）and aggressively funding Park
14、insons research. And Fox has become known as an author, writing two best-selling memoirs(回忆录) of his life before and after Parkinsons.With characteristic optimism, Fox describes his Parkinsons diagnosis in terms of what it has added to, not taken away from, his remarkable life. “I once said to someb

Charles had spent a long time studying the level of the water in the boat, and had discovered that, by evening, it had fallen
19、 very slightly. This it would seem, must mean that the boat was not taking in water, which was fortunate, because any attempt to empty it out suggested greater effort than he felt equal to. One other immediate problem had held his wandering thoughts for a few moments at long intervals. This was the
20、problem of his friend Harcourt. Charles realized that he was to put poor Harcourt in the sea. It should be a simple matter and take no more than a few seconds. Charles arranged in his mind exactly how it could most easily be done, but his body did not react to the suggestion of his mind. Charles tho
21、ught his hands might be too badly burnt to use. But then, suddenly, almost without knowing how he did it. Charles moved, stood up, bent over the body of poor Harcourt, lifted it and let it slip as gently as possible into the sea. Afterwards he stood in the stern(船尾）of the boat for a long time, watch
22、ing the color of the sea deepen and the sky become increasingly farther off with the coming of the night. In a curious way he felt strangely happy. The problem of his rescue had not yet begun to trouble him. After a time Charless returning interest in living showed itself in the simple form of hunge
23、r. With some difficulty, owing to the water in the boat, he examined its stores and found food and water in air-tight tins. He also found a neat package wrapped in green oiled silk. He unwrapped it and found maps. Neat, beautifully designed and printed spotlessly new, they lay across his knees and h

More than 300 people staged a sit-in protest against Egypts President, Mohamed Morsi, outside the gates of the presidential pa
28、lace.The protest is part of a political crisis in a country that is divided over the rule of the President，who just claimed victory in a landmark presidential election on June,18. In November, Morsi proposed changes to the countrys constitution. His opponents believe he is trying to gain more power
29、and will become a dictator(独裁者).His rivals took their protests to the streets. Tension came to a breaking point on Tuesday, as a vote on the constitution neared. Morsis supporters chased the protestors and tore down their tents. The rival groups threw stones and sticks at each other.Mohamed Elbarade
30、i, a Nobel Peace Prize winner and a rival of Morsi, accused the Presidents supporters of a “cruel and deliberate” attack against peaceful demonstrators. He believes that Egypts bitter division is very damaging to the country. “After 23 months of struggling to bring democracy（民主）to Egypt, is this the
31、 best we can do?” He told the Financial Times. “(It is) opening the door for possible situations such as more protests, armed conflicts, or even civil war.”Despite the crisis, Morsi shows no sign of backing down. He believes his supporters have the numbers to win in the election. Many Egyptians want
32、 an end to the political disorder that has scared off investors and tourists and hurt the economy.Today, Morsi returned to work in his office. U.S. Secretary of State Hillary Clinton weighed in on Egypts political debate, urging the need to continue talks on the new constitution, which should “respe

Now environmentalists say the species needs saving in real life too. On Sept. 13, the Center for Biological Diversity filed a petition（请愿书）that it hopes will prevent cl
37、own fish and seven other species that live in coral reefs from becoming endangered.There is no evidence that clown fish numbers are dropping. So why are scientists concerned? Shaye Wolf is an animal scientist for the Center for Biological Diversity. She says the coral reefs, where clown fish live, a
38、re becoming unhealthy. “Were asking for protection of the clown fish because its in trouble from climate change.”Clown fish protect themselves from predators（捕食性动物）by living in sea anemones(风花) that grow on coral reefs. Scientists have warned that coral reefs are likely to become the worlds first ec
39、osystem to disappear because of global warming. The reefs are at risk from increased levels of acid in the ocean, which comes from pollution from humans. The pollution damages a clown fishs sense of hearing, sight and smell. With damaged senses, young clown fish have trouble finding coral reefs to m
40、ake their homes. Sometimes the fish can become so confused that they are drawn to predators smells by mistake. “The longer we wait, the harder its going to be to save these unique creatures,” Wolf says.Clown fish face other threats too. They are among the worlds most commonly traded fish species. Wo
41、lf says protecting the fishand the coral reefs where they liveunder the Endangered Species Act will help.“We need to protect Nemo and all the other fishes that we care about,” Wolf says. “As the reefs go, so do the fish that depend on them.”The National Marine Fisheries Service will decide this Dece
42、mber whether these fish will be protected under the Endangered Species Act. Until then, as Dory from Finding Nemo says, “just keep swimming.”67.
