A
  Soon it may be harder to stop and smell the roses.
  Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.
  The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.
  "Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.
  "The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."
  Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.
  With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.
  The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.
  Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.
  The report was recently published in the journal,Atmospheric Environment.
  Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?
  Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.
  Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.
  "Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.
  "It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."
  But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.
  "The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.
  "It's something that is really worthwhile paying attention to."
  56.What's the passage mainly about?
   A.How greatly air plooution affects our lives.
   B.Effects of air pollution on bee populations.
   C.Measures to fight air pollution.
   D.The rapid decline of bee populations in the world.
  57.According to the passage,Jay Evans probably agrees that ______ .
   A.bees are the insect that suffers most from air pollution
   B.bees are at risk of dying out owing to air pollution
   C.the fading smell of flowers doesn't affect bees so greatly as was thought
   D.as is often the case,bees fail to locate the flowers because of the missing scents
  58.The word"exacerbate" in the last paragraph but one probably means ______.
   A.worsen B.improve C.get rid of D.decrease
  59.Which of the following is NOT true according to the passage?
   A.The more air pollution there is in a region,the greater the destruction of the flower scents.
   B.Bacteria,pesticides,and cellphone radiation are blamed for causing the decline of bees.
   C.The scent molecules produced by flowers in a less polluted environment oculd travel longer and farther.
   D.Air pollution does more harm to insects such as bees and butterflies than human beings.

  Experts say that agriculture provides fourteen percent of the world's greenhouse gas emissions each year.The gases released include carbon dioxide,a major cause of global warming.

  Twenty-one nations around the world recently joined forces to better understand and prevent greenhouse gas emissions from farms.The Global Research Alliance on Agricultural Greenhouse Gases was launched at the United Nations conference on climate change.The meeting took place in Copenhagen,Denmark last month.

  Agricultural experts blame a number of farm activities for producing greenhouse gases.For example,animal waste and cattle digestive systems release methane(甲烷,沼气)gas.Fertilized soil and the burning of crop waste also release harmful gases into the air.Experts say some methods of farming-turning the soil to prepare for planting-also release harmful carbon dioxide.

  An official of the European Commission's Directorate General for Research says agricultural greenhouse gas emissions can be cut.Maive Rute suggests feeding animals a diet designed to reduce emissions.

  The new agricultural research group says protecting against global warming is only part of its purpose.It says the world also needs to develop better farming methods to feed growing populations in poor countries.

  United States Agriculture Secretary Tom Vilsack said no one single nation can fight agricultural greenhouse gas emissions and increase food production at the same time.This is why the alliance is important for combining resources and finding new ones.

  The United States Department of Agriculture will increase spending on farm emissions research by ninety million dollars over the next four years.The total will reach one hundred and thirty million dollars.The U.S.D.A.will share the research with other countries in the Global Research Alliance on Agricultural Greenhouse Gases and support researchers from developing countries that belong to the alliance.Money from the Borlaug Fellowship Program will let the researchers study agricultural climate change with American scientists.

  Mister Vilsack said that just as climate change has no borders,there should be no borders for research.

(1)

In Paragraph 4,Maive Rute recommends ________.

[  ]

A.

increasing food production

B.

changing cattle digestive systems

C.

developing better farming methods

D.

giving animals the food meant to produce fewer emissions

(2)

The underlined word“alliance”in Paragraph 6 probably means ________.

[  ]

A.

action or state being joined together

B.

an agreement signed between countries

C.

a program or project set up for a research

D.

an organization formed for different goals

(3)

How much has the U.S.D.A.spent on farm emissions research so far?

[  ]

A.

130 million dollars.

B.

220 million dollars.

C.

40 million dollars.

D.

90 million dollars.

(4)

The purpose of the passage is to ________.

[  ]

A.

suggest a total ban on farm activities

B.

introduce the Copenhagen conference held last month

C.

appeal to more countries to cut agricultural emissions

D.

inform readers of the major cause of global warming
