US bees operation keeping groups have been attacked seriously by so called Colony （群体）Collapse Disorder．Almost 1/2 of their worker bees have vanished during the past season．This disorder has also been reported in Israel, Europe and South America．Bees fly away from the hive and never return．Sometimes they are found dead; other times they are never found．Many crops and trees depend on pollination^^}） by bees to help them grow．
A new report says a virus may be at least partly responsible for the disorder in honey bee colonies in the United States．This virus is called Israeli acute paralysis virus．It was first found in Israel in 2004．lan Lipkin at Columbia University in New York and a team reported the new findings in Science Magazine．Doctor Lipkin says the virus may not be the only cause．He says it may work with other causes to produce the collapse disorder．
The team found the virus in colonies with the help of a map of honey bee genes that was published last year．They examined thirty colonies affected by the disorder．They found evidence of the virus in twenty-five of them, and in one healthy colony．The next step is further testing of healthy hives．
The researchers suggested that the United States may have imported the disorder in bees from Australia．They say the bees may carry the virus but not be affected．
The idea is that unlike many American bees, the ability of Australian bees to fight disease has not been hurt by the varroa mite．This insect attacks honey bees, which could make the disorder more likely to affect a hive．Australian bee producers object to these suspicions．
And some researchers suspect that bee production in the United States is down mainly because of the weather．Honey bees gather nectar from flowers and trees．The sweet liquid gives them food and material to make honey．But cold weather this spring in the Midwest reduced the flow of nectar in many flowers．Many bees may have starved．Dry weather in areas of the country could also be playing apart．
Wayne Esaias is a NASA space agency scientist who keeps bees in his free time．He lives in central Maryland, where he has found that flowers are blooming a month earlier than they did in 1970, which may be partly responsible for the disorder. Wayne Esaias is organizing a group of beekeepers to document nectar flow around the country.

China is casting such a huge shadow on the United States that many Americans are struggling to learn Chinese in order to maintain their competitive edge, "Interest in learning Chinese among American youth and their parents has grown dramatically in the past five years," said Vivien Stewart at the Asia Society, a US group trying to bridge the gap between Americans and people of Asia and the Pacific．
China, the world's most popular nation, is critical to the United States because it is a leading trader, consumer and investor- Its political influence is also rising across the globe．It has replaced the United States as the world's largest consumer and become the second largest economy in the world after the superpower status and its telling effects politically, economically and culturally are driving the interest to learn the language, experts say．
From kindergartens to high schools, studies by the Asia Society show, there is a "rapid rise" in interest among pupils to study the Chinese language．
Even though the US State Department has stressed the Chinese language "critical " to national prosperity and security, the "current infrastructure （基础设施）to support recruitment （招生） of students and teachers as well as the growth of high quality programs is -badly inadequate," an Asia Society study says．The Society has set a target of having at least 5% of American high school students learning Chinese by 2015．"Millions of Chinese are learning English, but only 24,000 Americans are learning Chinese," said Andrew Corcoran of the San Francisco - based Chinese American International School．
The most popular languages after English in the United States at present are Spanish and French.

Unbelievable view appealed to me by accident．Just then, I checked once again: the somewhat tiny wood was having a leaf．Could I trust my own eyes? Had the hot sun annoyed me? After all, it as summer in Costa Rica, a country in Central America.
I left off, wiping sweat from my eyes．Then I moved the wood with my finger．It stopped．It looked up at me with big triangular eyes．Surprise! It was a mantid, a kind of insect, instead of a piece of wood．
The mantid was hanging upside down on a branch．Its wings made it look like a piece of tree bark．Then I noticed something else．The leaf wasn't a leaf at all．The hungry mantid was really eating another insect—a katydid．By now, all that was left of the katydid was a pair of wings．A few moments later, the wings dropped to the ground．The mantid folded its long legs．It sat still．Now it looked even more like a piece of wood than when I had first seen it．
I thought about how I had been fooled by these clever animals．Then I thought about how the two insects go about trying to trick each other．Both mantids and katydids are masters of make-up．Katydids are particularly good at it．Many look like something they are not．Katydids often look like plants．Many seem to be leaves．Others look like leaves of grass．All day, the bugs try to stay perfectly still．Because their bodies look like plants, most animals interested in killing them don't bother them while katydids eat plants．
