Cancer is a leading cause of death around the world.

    When it comes to cancer, the sooner you know you have it, the better your chances of surviving are.

    A new blood test could change the way doctors and researchers find cancer in patients. Researchers say the test could provide some hints of the early forms of the disease.

    Gareth Jenkins is a professor at the University of Swansea. He says he and his team did not look for cancer. They instead looked for a by-product of cancer, mutated (突变的) red blood cells. They looked for, what Jenkins calls, the collateral (附带的) damage of cancer—the damage left by the disease.

    “In this blood test we don't measure the presence of cancer，we measure the presence of mutated red blood cells which are the collateral damage that occurs—a by-product of the cancer developing.''

    The researchers used normal laboratory equipment to perform the tests. This equipment looks for changes in the structure of millions of red blood cells. Those mutated cells lack a surface protein (蛋白质) that healthy cells normally have.

    “The goal of the test is looking for very rare cells which have picked up a mutation. The number of mutated red blood cells in a healthy person is around 5 or so mutated cells per million; so, you have to look at millions of red blood cells to discover those rare events. The number increases in cancer patients—it goes up to 40 or 50 on average.”

    The researchers tested blood from about 300 people, all of whom have cancer of the esophagus (食管). Patients with esophageal cancer have high levels of mutated red blood cells. Jenkins says that at this point he is not sure if other cancers would produce similar results.

    The hope is that the new test could one day become part of commonly used medical methods to find out if a person has cancer. These new technologies could save millions of lives.

    Washington—Wild applause broke out at the Parent Teacher Association national offices when several government spokespeople announced a decision to return the subject of civics(公民学) to high school curricula nationwide.

The decision is symbolic of the new agenda to restore(恢复) the United States Constitution to its pre-Bush-era status. In a joint statement, Senators Harry Reid, Republican of Kentucky, said that the decision proves the two parties can work together on an issue of national importance.

    The announcement came following a series of school strikes organized by parents angered by a recent study by the National Opinion Research Center. The findings showed a total ignorance of government structure and citizens rights by graduating high school seniors.

    Some of the fallacious opinion and beliefs mentioned in this cross-country study included: the president has the power to interpret treaties(条约); the president is not bound（约束） by law; the vice president is independent of all three branches of government; torture（刑讯） is not a punishment and therefore cannot be considered “cruel and unusual”.

    The study noted that many students' political consciousness dated back only three years — in other words, their awareness of constitution rights had been entirely formed during the Bush administration.

    The study also found that students were growing incapable of telling the difference between living figures, historical figures, and corporate-licensed figures such as cartoon characters.

    The revived civics courses will teach students about the structure and function of each branch of government, the theory of checks and balances, theories of the role of government, and constitutional(宪法的) law.

    "We have so much work in front of us." said Los Angeles area high school teacher Roberta Morales. "Trying to develop students' sense of citizenry and the public good and undo so many self-centered individualistic messages will take great effort."

    Come to our college this summer and make yourself shine at English.

    It is estimated that more than half the world's population is bilingual (双语的), and in an increasingly globalised world, there are obvious benefits of speaking more than one language. However, for many years, parents were advised not to teach their children to speak more than one language from birth. Learning two or more languages simultaneously (同时) was believed to cause confusion and slow down academic development. While it is certainly true that children who are learning to speak more than one language as their mother tongue will often mix the languages up or speak a little later, these are temporary problems, and there is no reason to avoid teaching a child more than one language.

    In fact, there are plenty of reasons to encourage your child to become bilingual from birth. As well as the obvious benefits of being able to communicate with more people, and the possibility of earning more money, children who speak more than one language have been shown to score more highly in achievement tests at school. This is true for mathematics as well as tests of verbal (言语的) skills.

    And in later life it has been found that bilinguals, on average, will tend to develop Alzheimer's disease five years later than monolingual speakers. Speaking three or more languages offers even more protection. It seems that the increased number of connections within the brain allows bilinguals to cope better with brain damage.

    But is it too late if you haven't already learned a second language in childhood? It used to be thought that the adult brain was very fixed, but recent research has shown that we continue to develop new connections in the brain throughout our lives, meaning that it's perfectly possible to learn another language to a high standard. Older learners are less likely to have native-like pronunciation, but they are better at learning vocabulary as they are able to use far more skills and strategies than children. And learning a language is like using a muscle – the more you use it, the stronger it gets, meaning that you will find your third language easier than your second, and so on.

Mountain torrent that killed 7, injured 8 at scenic spot in Sichuan stirs reaction

There was a tragic death of seven people, and an injury of eight others in a flash flood at a scenic spot in Sichuan province. The {#blank#}1{#/blank#} (safe) of tourists visiting unregulated scenic spots prone to flash flooding has become a matter of public issue.

At about 3:30 pm {#blank#}2{#/blank#} Saturday, a flash flood hit Longcao valley, a popular tourist spot in Longmenshan town, Chengdu. Several tourists were unable {#blank#}3{#/blank#}(escape) before the flood hit.

In the wake of the tragedy, tourists have been cautioned against visiting mountainous locations susceptible to flash flooding during the summer flood season.

"Mountain climates are very {#blank#}4{#/blank#} (complicate). There can often be heavy rain at the top of a mountain and clear weather below, {#blank#}5{#/blank#} can sometimes lead to flash floods or mudslides that people lower down the mountain are unaware of." Xie Hong, a researcher from the Institute of Mountain Hazards and Environment of the Chinese Academy of Science said.

When it rains, slopes become prone to instability and to {#blank#}6{#/blank#} (disaster) such as flash floods, mudslides, rockslides, landslides. According to the villagers, {#blank#}7{#/blank#} flash flood hit within seconds in this accident.

Xie said that although the warnings are {#blank#}8{#/blank#} (clear) posted at such places, some people are quick to forget about such tragedies.

He suggested {#blank#}9{#/blank#} (teach) a better understanding of the way weather behaves in the mountains in schools so that awareness of potential danger is ingrained at a young age. He hopes that tragedies like this can {#blank#}10{#/blank#} (avoid) in the future.
