     China has recently been faced with serious issues of product safety.In Panama,it is said that medicine
made with a poisonous chemical sickened some people.A Chinese company had identified it as
diethylamide glycol(乙二醇),a lowcost substitute commonly used in automobile antifreeze(防冻剂).
     Some countries have banned Chinesemade toothpaste containing diethylamide glycol.China has now
told companies to discontinue its use,even though it says the toothpaste is safe. Another industrial chemical,
melamine,was found in wheat flour used to make pet food in North America.Thousands of dogs and cats
became sick.
     The United States has restricted some imports of Chinese seafood because they contained banned
substance.And questions have been raised about other products,including children"s toys covered with lead
paint.
     Chinese officials promised to provide the European Union,the biggest trading partner,with detailed
reports on enforcement efforts against unsafe goods.
     Meglena Kuneva,commissioner(理事) for consumer protection of the European Union said China
should have kept its promise.
     China recently closed three companies linked to the Panama and the pet food scare.And it dismissed
the former head of its food and drug administration.He was found guilty of corruption(腐败)for approving
unsafe drugs.This week,a conference of the State Council approved a proposed special measure on the
supervision of food safety. The Xinhua News Agency said it calls for stronger controls over producers,
greater responsibilities for government and more serious punishment for illegal activities.
     But Chinese officials have accused some foreign media of overstating problems with goods made in
China.They say food imports from the United States also fail inspection sometimes.Next week,American 
and Chinese food safety officials are planning to hold 5 days of meetings in Beijing to discuss cooperation.

tick bites.Young cows are most at risk;they can die within days.Farmers and herders
can lose up to half or more of their calves to east coast fever.
      The disease is widespread in eleven countries.And experts say it now threatens ten
million more animals in new areas including southern Sudan.
      Researchers first developed an experimental vaccine against east coast fever thirty
years ago.The vaccine works by a process called "infection and treatment".The animals
are infected with whole parasites and treated with antibiotics at the same time.This keeps
the disease from developing.
     Controlling east coast fever has meant a better life in areas that have gotten the vaccine.
For example,the vaccine has been available for a group of Maasai herders in northern
Tanzania for about seven years.They used to lose threefourths of their newborn calves
each year.Now,most survive.As a result,many people have extra cattle to sell,and use the
money to pay for school for their children.
     But making the vaccine more widely available-especially in rural areas-has been difficult.
Farmers have been using supplies produced in the nineteen nineties.Recently there was a
shortage.The International Livestock Research Institute made one million doses at the request
of African officials.But that supply is only temporary.Another problem is that the vaccine
must be kept extremely cold.
      Now,the nonprofit Global Alliance for Livestock Veterinary Medicines is trying to
expand production and lower the cost.GALVmed spokesman Hameed Nuru says mobile
phones have helped lower some barriers to distribution.
     HAMEED NURU:"Now,with the advent of cellular technology,most of the people we
do reach,such as the Maasai pastoralists,they all have cell phones.And they now call the
delivery agent who can now come and meet them at a particular place and do the vaccination
for them."
      The vaccine is not cheap.But Hameed Nuru says the herders get together to sell a bull
and use the money to vaccinate all their animals.They understand that they are getting value
for their money:A cow is worth nearly twice as much if it is vaccinated.
      A goal is to have local people develop businesses supplying the vaccine.
      HAMEED NURU:"People are now seeing that they can actually make a business from
supplying this vaccine and getting out to the very rural areas where there is a market for this."
     The efforts are supported by the Bill and Melinda Gates Foundation and the British
government.

          1The goal here is to limit carbon dioxide and other greenhouse gases, which are closely associated
to the big problem of global-warming.
     Strategy 1: Bring your own cup to Starbucks
     You’ll get a 10 cent discount, and it’s one less paper cup to end up in a landfill. While  you’re  there,
pick up some free bags of spent coffee grounds to use as ‘‘green’’ fertilizer in your garden.
     The payoff     2    
     Strategy2: Turn off your computer
     When in standby mode, your PC is still using energy.    3       
     The payoff: Turning off a monitor for 40 hours a week may only save $ 5 a month, but it reduces
CO2 by 750 pounds
     Strategy 3: Reuse plastic bags
     Instead of throwing away 100 billion plastic bags a year, try and get a second, third, or tenth use out
of them. Better yet, next time you shop, try a reusable bag.
     The payoff    4     The amount of oil it would take to make just 14 plastic bags would run your car
for one mile.
     Strategy4: Use recycled paper in the bathroom
     Most of the toilet paper we use is made from trees found in forests previously untouched by humans.
     The payoff: If every household replaced one roll of toilet paper with a recycled one, 424000 trees
would still be standing. Look for eco paper towels too.
     Strategy5: Buy energy-efficient appliances(电器)Replace the old fridge with an Energy Star appliance and you’ll use 15 percent less energy.     5    
     The payoff: If we all used one Energy Star appliance at home, it would be like planting 1. 7 million
acres of new trees.

A. You can be proud of yourselves, even if you can only make one or two of these green changes.
B. Adding green to your garden is beautiful and earth-pleasing.
C. It might be a little expensive to buy, but you’ll save money on your electricity bills and help the
environment.
D. In fact, 75 percent of electricity used in your home comes from electronics that are turned off.
E. You’re reducing pollution.
F. The store won’t create more waste when they throw away a cup.
G. Just one tree will help make cleaner air and save the environment from 5000 pounds of hot carbon
dioxide each year.

     The influenza virus(流感病毒) or the flu is spread from person to person in the air when an infected
person coughs or sneezes.There are 3 types of the flu:
     -Type A viruses can infect people,birds,pigs,horses,seals,whales,and other animals,such as avian flu
or bird flu.
     -Type B viruses infect people and result in smaller outbreaks(爆发). People infected with type B
viruses are often hospitalized with higher death rates.
     -Type C viruses cause mild illness in humans without the onset of an epidemic (流行病).
Most people are familiar with the symptoms of the flu,but they can be mistaken for a severe cold.The flu
infection is far more serious and can cause severe health complications (并发症). There are many viral
infections that can cause flulike symptoms.It is better to visit your doctor so other possibilities can be
ruled out before your obtaining treatment.
     The flu virus attacks the body"s cells and changes into different forms,which is why people who have
received the flu shot (流感疫苗接种) may still get ill with the flu.The influenza virus is transmitted_
through direct contact with infected persons such as by inhaling (吸入)droplets when they have coughed
or sneezed.It can also be spread by handling objects such as doorknobs and telephone receivers that an
infected person has been in contact with.
     If you have the flu,get plenty of bed rest and drink lots of fluids.Most people recover from the flu in
one to two weeks.Doctors often recommend flu vaccines( 疫苗) for highrisk groups such as young
children,the elderly,those with chronic(慢性的) diseases,weak immune systems,or professionals working with highrisk groups.


1. Which of the following is true about bird flu?
A. It is a disease which can spread among humans and animals.
B. Only animals and birds but not humans can be infected by this kind of virus.
C. This kind of disease can cause higher death rates among humans.
D. Bird flu won"t cause the outbreak of an epidemic among humans.

2. When you cough or sneeze,a proper suggestion given by the writer is to ________.
A. take some medicine at once
B. see a doctor to make sure of the disease
C. drink more water
D. take more exercise and bed rest

3.  Why some people who have received flu vaccines are still down with the flu?
A. Because the flu is not easy to be treated.
B. Because the flu can spread from person to person.
C. Because people are easy to catch cold.
D. Because the flu virus may have different forms.

4. Once you are down with the flu,what should you do?
A. Take flu vaccines.
B. Improve immune systems.
C. Take enough bed rest.
D. Do more physical exercise.

     Now, we know that if we do not get enough vitamins, we are at risk of developing a number of
diseases. As a result, vitamin supplements(补品),though expensive, are popular with people who
worry that they are not getting enough vitamins from the foods they eat. But contrary to what many
people think, medical experts have found little evidence that most supplements do anything to improve
health or protect against disease.
     In fact, medical experts warn that taking too many of some vitamins can be harmful. For example,
too much vitamin E can cause bleeding. People should discuss what vitamins they take with their doctors,
as some vitamins can produce harmful side effects when mixed with medicines.
     Experts, however, do say that sometimes vitamins can help prevent disease. People who know they
lack a particular vitamin should take vitamin supplements. Some older adults, for example, may not have
enough vitamin B-twelve. This is because, as people get older, their body loses its ability to take it from
foods. Also, people who spend much time inside may need some extra vitamin D as the skin makes this
vitamin from sunlight.
     Different vitamins are found in different foods. Vitamin A is found in fish liver oil. It also is in the
yellow part of eggs. Sweet potatoes, carrots and other darkly colored fruits and vegetables contain
substances that the body can change into vitamin A. Vitamin B-twelve is found in green leafy vegetables
and other foods, like fruits. Vitamin K can be found in pork products.
     In fact, for most people, a balanced diet can ensure enough of the vitamins our bodies need. So, it is
important for us to eat a mixture of foods every day to ensure that we get enough vitamins our bodies
need.

1. What is probably talked about before this passage?
A. How many vitamins a person"s body needs.  
B. How many vitamins some foods contain.
C. The benefits that vitamins bring to our health.
D. What people should do to stay healthy.

2. Vitamin supplements are popular with people because ________.  
A. people mistakenly think that they are good for their health
B. they contain more vitamins than the foods people eat
C. food does not provide enough vitamins people need
D. people fear that a lack of vitamins will lead to disease

3. From the passage, we can learn that medical experts advise people _________.
A. never to take any vitamin supplements  
B. to depend only on food for their vitamins
C. not to take any vitamins together with medicines
D. to consult doctors before taking vitamin supplements

4. For people who lack Vitamin B-twelve, they can eat more from _______.
A. sweet potatoes  
B. green leafy vegetables  
C. pork products  
D. eggs

     It may sound strange, but cutting down a real tree for Christmas is actually greener than going with
the artificial kind, one scientist says.
     "It is a little confusing to people," said Clint Springer, a biologist at Saint Joseph"s University in
Philadelphia. Because of concerns over deforestation (砍伐森林) around the world, many people
naturally worry that buying a real tree might contribute to that problem. But most Christmas trees for
sale these days are grown not in the forest but on tree farms for the purpose of being cut.
     Moreover, from the viewpoint of greenhouse gases, real trees are "the obvious choice". Live trees
actively release oxygen as they grow, and meanwhile remove carbon dioxide from the atmosphere.
After they have been cut and Christmas is over, they"re usually cut into smaller pieces for mulch (覆
盖物). As mulch, the bits of trees very slowly release carbon dioxide back into the atmosphere. So in
the end, a real Christmas tree is carbon neutral, putting the same amount of carbon dioxide back into
the air as it took out (although much more slowly).
     The tree farms that grow the trees also replant after the trees are cut. Artificial trees, on the other
hand, don"t come out even in the carbon balance. Petroleum (石油) is used to make the plastics in
artificial trees and lots of carbon dioxide-creating energy is required to make and transport them.
Because these trees just end up in the places where waste is buried under the ground after use, "those
greenhouse gases are lost forever," Springer said.

1. The author presents the text mainly by       .
A. giving descriptions
B. making comparisons
C. listing figures  
D. analyzing different opinions

2. Real trees for Christmas are better than artificial trees probably because       .
A. real trees cost buyers less money  
B. real trees are more beautiful
C. real trees don"t cause any pollution
D. real trees can be used for a longer time

3. The underlined part "carbon neutral" in the third paragraph can be best replaced by "      ".
A. not releasing more carbon
B. absorbing carbon dioxide
C. causing much waste
D. releasing carbon dioxide

4. The purpose of the text is to tell us       .
A. the reasons for using real trees for Christmas
B. the environmental protection tips for Christmas
C. how to choose artificial Christmas trees
D. how to spend a much greener Christmas
