1、 said Reed. Even a minor shift back to the west could bring direct impacts to portions of the coastline from the mid-Atlantic northward.Emergency officials said residents in low-lying coastal areas from North Carolina to Maine should be prepared for possible evacuations in coming days. They said res

2、idents should monitor local weather officials, who may begin issuing storm warnings as Earl moves closer to the U.S. mainland.Federal Emergency Management Agency Administrator Craig Fugate said the main concern is possible flooding.The primary threat here is going to be storm surge. We use tropical

3、force winds, however, as a benchmark to have an evacuation completed because many of the overland routes will include high bridges and other things that tropical force winds make it extremely dangerous, said Fugate.Earlier, heavy rains from Earl caused flooding in low-lying areas of Antigua, and win

4、ds ripped out trees and blew down power lines on the nearby island of St. Martin. Officials in the U.S. Virgin Islands and Puerto Rico said they are working to restore electricity to more than 200,000 people who were affected by the storm.Meanwhile, forecasters said residents of the eastern Caribbea

5、n should prepare for possible impact from another storm that has formed in the Atlantic. Tropical Storm Fiona is expected to reach parts of the area by Wednesday.Bill Reed of the National Hurricane Center says Fiona is not expected to come as close to land as Earl did.It is forecast to remain northe

6、ast of the islands and not impact the U.S. Virgin Islands and Puerto Rico in the same places that were hit by Earl. It is running parallel to Earl and off to the east, maybe impacting Bermuda by the weekend, said Reed.Current forecasts show Fiona moving north on a path that will keep it far off the

7、U.S. East Coast.2、第62届艾美奖揭晓 爆出两个“三冠王”U.S. television honored its best programs Sunday at the annual Emmy awards in Los Angeles. Mad Men was named best dramatic series. Modern Family was named best comedy. Key Emmys also went to television movies and a mini-series based on real-life stories.Mad Men,

8、which is set at a 1960s New York advertising firm, won its third consecutive Emmy as best drama series. And a satirical look at the modern American family, Modern Family was named best comedy and earned Emmys for its writing and for supporting actor Eric Stonestreet.The musical-comedy series Glee ha

9、d 19 nominations heading into the awards, but the series won just two Emmys, for supporting actress Jane Lynch and series creator and director Ryan Murphy.Bryan Cranston was honored for his portrayal of a drug dealer in the series Breaking Bad and Kyra Sedgewick for her role as a deputy police chief

10、 in The Closer.Top comic acting honors went to Edie Falco of Nurse Jackie and Jim Parsons of The Big Bang Theory, a series about nerdy scientists.Temple Grandin, a TV film about a noted animal scientist who has struggled with autism, was named best television movie, and earned an acting award for Cl

11、aire Danes, who portrays Grandin. Supporting performers Julia Ormond and David Strathairn and director Mick Jackson also earned Emmys.Autism is a developmental disorder that causes problems in communicating with others, but Grandin has overcome her disability to become a respected author and advocat

12、e for the humane treatment of livestock. Producer Emily Gerson Saines, who is herself the mother of an autistic child, thanked Grandin for her work in spreading knowledge about the condition.Autism has reached epidemic proportions, so on behalf of all the parents like myself who have a child with au

13、tism, Temple Grandin, you are our hero, Saines said.The Pacific, a 10-part miniseries from producers Tom Hanks, Steven Spielberg and Gary Goetzman, was named best miniseries. The project cost more than $200 million, and it tells the intertwined stories of American Marines fighting in the Pacific dur

14、ing World War II. Hanks thanked his Australia-based crew, who worked under harsh conditions.So heres hoping that some very bright person right here in the room or at home watching can help find a way to keep the spotlight burning on these heart-breaking situations that continue to be heart-breaking

15、long after the cameras go away, Clooney said.The Emmys are presented by the Academy of Television Arts and Sciences and are considered the highest honor in American television. Late-night talk show host and comic Jimmy Fallon hosted this years show.3、蛙的皮肤可能为细菌带来“死亡之吻”Worldwide threatThe emerging bat

16、tle against drug-resistant bacteria poses a huge threat to public health worldwide. That threat has loomed larger as the number of effective antibiotic drugs has dwindled.J. Michael Conlon, a biochemist at the United Arab Emirates University, says frog skin, which protects the amphibians from injury

17、 and disease, is coming to the rescue by providing a wealth of new antibiotic compounds to fight drug resistant fungi and bacteria.Frogs of necessity have to live in a warm moist environment that is very conducive to the growth of micro-organisms. Theyve been around for a long, long time, at least 3

18、00 million years says Conlon. So, its not so surprising that, over the course of evolution, they have developed defenses against these invading pathogens.Conlon has identified germ-fighting chemicals from more than 200 frog species from around the world by isolating peptides or strings of proteins t

19、hat have the ability to kill bacteria and fungi.He says the challenge is to get those agents to work in humans. The problem is that as well as efficiently killing micro-organisms, they are to various degrees toxic to mammalian cells. So its not a great idea to cure infection if you kill the patient

20、at the same time.Fighting two major pathogensConlons laboratory in the United Arab Emirates works with samples from frogs gathered collaboratively by scientists in Japan, France and the United States.The naturally occurring compounds are first purified and then synthesized. At that point, structural

21、 changes are made in the molecules. The results have proved to be less toxic to human cells.Conlon says the new compounds show promise in fighting two major pathogens, the well known methicillin-resistant Staphylococcus aureus （MRSA） and a new emerging bacterium, Acintobacter baumanni. This has been

22、 called the Iraqibacter because many wounded soldiers in Iraq have developed infections by this microorganism.Frog mouthwashConlon also sees great potential for other antibiotic applications from creams and ointments for wounds to treatment of foot ulcers. He adds that the peptides have shown to be

23、very effective against oral pathogens. So we are interested in the possibility of incorporating of incorporating them into a mouth wash.But Conlon says as a researcher in a small university lab, he can only take the product so far. To bring a drug from the laboratory to the pharmacy literally costs

24、hundreds of millions of dollars. We really need a partner in the pharmaceutical industry with which to collaborate.Should that partner step forward, J. Michael Conlon predicts that some frog-skin derived compounds could make their way into clinical trials and into marketable drugs within five years.

25、4、美军撤离伊拉克对中国意味着什么？In announcing the withdrawal of U.S. combat troops from Iraq,President Obama made it clear that Afghanistans turn is next.Next August,we will begin a transition to Afghan responsibility,he said.The pace of our troop reductions will be determined by conditions on the ground,and our

26、support for Afghanistan will endure.But make no mistake-this transition will begin because open-ended war serves neither our interests nor the Afghan peoples.Analysts say the Iraq withdrawal has highlighted for leaders in Iran,Pakistan and other regional states that the United States intends to pull

27、 out its forces.Larry Goodson of the U.S. Army War College says no one is considering the implications more than Afghan President Hamid Karzai.All of the regional actors now alter their calculus a bit,but none more obviously and skittishly than Karzai because he is really the one whose neck is in th

28、e noose.He is the one who would literally be hanging from a lamppost within a month,let us say,if the U.S. and NATO forces withdrew today.Or at least that is what I think would happen.Morale boost for the TalibanPresident Karzai recently told a visiting U.S. congressional delegation that the withdra

29、wal date is a morale boost for the Taliban.Larry Goodson says Mr. Karzai might be looking for ways to keep U.S. troops around longer than President Obama and his advisors have planned.I think he is looking for the,O.K.,the U.S. is no longer here or maybe I can,through certain political moves and man

30、euvers,continue to play the United States and keep them here a bit longer or keep them engaged in some fashion a bit longer.I realize I attributed some Machiavellian sort of tendencies to Hamid Karzai.But I think that he has demonstrated that he has got some political skills,he said.The U.S.-Karzai relationship has
