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.

There are several major aspects to this problem．
Population
Most problems of the environment come from population growth．In 1700 there were 635 million people in the world; in 1900 there were 1．6 billion; in 1950, 2．5 billion; and in 1980, 4．4 billion．In the year 2010 there will be 7．3 billion．More people need more water, more food, more wood, and more petroleum．
Distribution
Scientists say there is enough water in the world for everyone, but some countries have a lot of water and some have only a little．Some areas get all rain during one season．The rest of the year is dry．
Petroleum
We are using up the world’s petroleum．We use it in our cars and to heat our buildings in winter．Farmers use petrochemicals to make the soil rich．They use them to kill insects on those plants．These chemicals go into rivers and lakes and kill the fish there．Thousands of people also die from these chemicals every year．Chemicals also go into the air and pollute it．Winds carry this polluted air to other countries and other countries．
Poverty
Poor farmers use the same land over and over．The land needs a rest so it will be better next year．However, the farmer must have food every year．Poor people cut down trees for firewood．In some areas when the trees are gone, the land becomes desert．However, people need wood to cook their food now．Poor people cannot save the environment for the future．
We now have the information and the ability to solve these huge problems．However, this is not a problem for one country or one area of the world．It is a problem for all humans．The people and the nation of the world must work together to protect the world’s resources．No one controls the future, but we all help make it．
小题1:According to the passage, our world is being destroyed mainly because ______．
| A．pollution is getting worse and worse |
| B．population are increasing greatly |
| C．we humans are using up all of our natural resources |
| D．distribution is not reasonable． |
| A．having things in the right place at the right time． |
| B．cutting down forests and selling them to other countries． |
| C．building water systems to carry water to farms． |
| D．conserving our natural resources |
| A．The World Being Destroyed |
| B．A Serious Problem We Should Pay Attention to |
| C．Aspects That Destroyed Our World |
| D．Conserving the World’s Natural Resources |
History really seems to matter here．Buttons first appeared only on the clothes of the rich in the 17th century, when rich women were dressed by servants．For the mostly right-handed servants, having women’s shirts button from the left would be easier．On the other hand, having men’s shirts button form the right made sense, too．Most men dressed themselves, and a sword drawn from the left with the right hand would be less likely to get caught in the shirt．
Today women are seldom dressed by servants, but buttoning form the left is still the standard for them．Is it interesting? Actually, a standard, once set, resists change．At a time when all women’s shirts buttoned form the left, it would have been risky for any single manufacturer to offer women’s shirts that buttoned from the right．After all, women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch．Besides, some women might have found it socially awkward to appear in public wearing shirts that buttoned from the right, since anyone who noticed that would believe they were wearing men’s shirts．
小题1:What is surprising about the standard of the clothing industry?
| A．It has been followed by the industry for over 400 years． |
| B．It is different for men’s clothing and women’s． |
| C．It woks better with men than with women． |
| D．It fails to consider right-handed people． |
| A．They tended to wear clothes without buttons． |
B．T hey were interested in the historical matters． |
| C．They were mostly dressed by servants． |
| D．They drew their swords from the left． |
| A．adopting men’s style is improper for women |
| B．manufacturers should follow standards |
| C．customs are hard to change |
| D．modern women dress themselves |
| A．analyzing causes | B．making comparisons |
| C．examining differences | D．following the time order |
The report measured a city’s housing market along the following guidelines. An “affordable” home required three times or less of the average family’s income to purchase. At four times earnings, a home fell into the “unaffordable” category. And a “seriously unaffordable” home needed five times a family’s income. In Australia, homes in the least affordable city cost just about 9.5 times the average income. Sydney, Perth, and Melbourne were only a little under this figure.
Australian officials offered little comment, apart from a general statement on the dismal findings. These prices make the possibility that many Australians will one day own a home largely unbelievable. Land rationing (配给制) and excessive development charges have raised prices, and the problem will only be solved through urgent action by the Rudd government.
Some American cities were also included on the least affordable list, four of which were in California. America is still involved in a mortgage（抵押）crisis, though, affecting the affordability of homes. Yet a number of US cities garnered “affordable” status, namely Dallas and Kansas. Australia had no cities listed in the top fifty places with affordable homes.
The survey suggests that you can find affordable homes in most places, just not if you’re Australian and choose to live down under.
小题1:To buy an affordable house, you should pay _____.
| A．3 times or less of the average family’s income |
| B．4 times or less of the average family’s income |
| C．5 times or less of the average family’s income |
| D．9.5 times or less of the average family’s income |
| A．The rising family’s income. |
| B．The demand over supply. |
| C．The excessive development charges. |
| D．The decrease of land. |
| A．cheerful | B．satisfactory | C．difficult | D．gloomy |
| A．Affordable Houses |
| B．A House is a Dream First |
| C．Housing Bubble |
| D．Homes Too Expensive |

China’s economic growth “hard to predict”
The worsening global economic situation makes it difficult for China to predict its growth for next year, a senior official said on Friday.
“How fast China’s economy will grow next year is uncertain,” Liu He, deputy director of the Office of the Central Leading Group on Finance and Economy Work, told China Daily.
“To a large extent, the rate will be decided by the external(外部) situation,” Liu said during a discussion with Swedish Prime Minister Fredrik Reinfeldt and other economists in Beijing.
“This year, GDP is estimated to grow at 9.4 or 9.5 percent, down from 10.6 percent last year,” he said. “However, the impact of the current financial turbulence on our economy is much less than on the rest of the world.”
Nicholas Stern, a former UK government advisor, also told China Daily it will take at least one or two years for the world to recover from the recession, which is now spreading from the US and the UK to the rest of the world.
“We don’t know how long the recession will last, but it is unlikely to be short,” he said.
Liu said China can use the downturn(衰退) as an opportunity to restructure its economy, which has relied heavily on government investment, foreign trade and low-cost technology over the past years.
“When the economy is experiencing fast growth, companies are unwilling to upgrade their technologies,” Liu said.
“The slowdown gives such firms the opportunity to enhance(提高) their competitive edge through better technologies.”

People in Shanghai can quench their thirst with high quality water if the Shanghai Water Authority (SWA) is able to make good on its word. It has vowed to make the city’s water match its status as a world class city.
“The current tap water quality meets national standards, but, compared with that of the European Union and the United States, it still needs to be improved.” said the SWA’s director general, Hang Jiayi.
In other developed countries, water fountains can be found almost everywhere—people do not bother with bottled drinking water.
By 2020, the water of the Huangpu River will be treated to reduce the amount of organic waste in it. Major water works that draw water from the Huangpu will need more treatment facilities to improve the colour, texture, ammonia(氨)and nitrogen content before 2010.
These treatment facilities are expected to cost 4 billion yuan, something that could affect the price of water, according to Chen Yin, SWA’s deputy director general.
Chen said that replacing water pipes was also a key project. The city’s aged pipes are mostly to blame for the bad water quality.
The SWA has started the water facilities renovation(更新)work, including the more than 14,000 kilometres of indoor piping, 107,000 tanks on top of the buildings, and more than 6,000 underground facilities.
World Water Day came on March 22, and this year’s theme is “Water for the future”. Beijing is also drawing up plans during China’s Water Week, which runs until March 28.
By 2010, the water for the Shanghai EXPO is to be above World Health Organization standards. And, the people of Beijing will be able to drink their tap water as well.
小题1:People in Shanghai can drink their tap water_____.
| A．by 2020 | B．in the first half of this year | C．by 2010 | D．by 2008 |
| A．The water of the Huangpu River will be treated. | B．Aged water pipes will be treated. |
| C．Water facilities must be renovated. | D．Water fountains must be found. |
| A．The tap water quality in Shanghai hasn’t met national standards. |
| B．World Water Day fell on March 22 this year. |
| C．The people of Beijing cannot drink their tap water now. |
| D．The treatment of the water of Huangpu River has been finished. |
| A．The cost of treating the tap water. |
| B．How to reach the water standards of developed countries. |
| C．The project for making tap water drinkable in Shanghai and Beijing. |
| D．The progress of treating the water of Huangpu River. |
