10.The earth is dying before us yet we sit and watch.If the TV or the game system breaks,we run off to the stores to get it fixed immediately no matter what the cost.Why aren't we willing to fix our earth?Are our televisions and game systems more important to us than where we live?Where shall we continue to live,until the end of time?
The earth is our home and cannot be replaced.We must take care of it.We have come up with so much technology that limits us instead of helping us.Take that game system we run to repair.What does it do?It occupies kids'time!The earth has already given kids plenty of entertainment in the forms of fields and hills,forests and plains,water and land.However,instead of using what the earth has given us,and helping kids by giving them exercise as they run around,we decide to ruin kids'minds with game systems that glue them to the screen for hours,and make them ignore their homework and chores.We have polluted this earth by making these things which do not even help in any way!
We have already messed up this world,we have ruined the air,water,and animals that it has so willingly provided for us.We need to stop this destruction of life and bring back the world we had before.It will not be easy,but everybody can help!What about something as simple as turning the lights off when you leave a room?Recycling what can be recycled?Picking up litter?Donating money to an environmental organization?None of these things are very hard.We can't just always say,"Oh,the earth is a mess.Ah,well,those big companies that are polluting so much can stop and fix it."Instead,we need to help out.It's not only those big companies; it's everyday things that we do too that are ruining the earth.So stop and think about what you can do to make a difference to our world!

5.Researchers may have discovered a perfect material of dieting----low fat cake and cheese.
British researchers say they have created a protein (蛋白质) that fat perfectly.
The proteins will enable food producers to remove much of the fat used in their products but without reducing product quality.
Funded by team from University of Edinburgh,the researchers have produced the modified (调整了的) proteins that easily break down and therefore work nearly the same as the fats do during food production.
"We've paved the way for the development of modified proteins that can be used to produce a wider ranger of appealing low-fat foods,"said Dr.Steve Euston,who led the research.
"The result could be important for health benefits,as well as a reduction in the burden on the National Health Service (NHS) caused by many weight-related health problems."
Protein-for-fat substitution (替代品) is not a completely new idea,but to date it has been limited to products such as yogurts.
In cheeses and cakes it has proved less successful in ensuring the original taste and texture fundamental to consumer satisfaction,mainly because proteins could not mimic the behavior of fats closely enough.
By studying the proteins'chemical structure,the team has developed a detailed understanding of how proteins behave when they are heated or go through other food producing processes.
The proteins could encourage development of a wider choice of low-fat foods,helping consumers to eat more healthily and reducing weight-related health problems.
The team has achieved particularly promising results in using proteins to replace eggs,which is commonly used in bakery items.
Such substitution not only cuts fat content; because eggs can be subject to sharp changes in price,it could also cut the cost products and so encourage consumers to eat more healthily.

47.What can we learn from the passage?A
A.The NHS will benefit from this new finding.
B.the research team is funded by food producers.
C.Protein for fat substitution is a completely new idea.

15."Drink your milk.It's good for you!"You've probably heard that many times,and it's true.Milk contains calcium,which is a necessary nutrient for keeping bones and teeth healthy and strong.The U.S.government even requires milk as part of the National School Lunch Program,saying that students should drink one cup of fat-free or low-fat milk at each meal.
Last Thursday,however,a group of doctors asked the government to remove milk from the lunch program.The Physicians Committee for Responsible Medicine (PCRM) says,"Milk is high in sugar,high in fat and high in animal protein,all of which have negative effects on health.""One of the only reasons people talk about dairy,or promote it,is that it is going to help build strong bones."says Dr.Neal Barnard,president of the PCRM.There are better and healthier ways to get calcium such as eating beans,broccoli,cereals and tofu.Orange juice and soymilk that have calcium added to them also supply the nutrient.
Of course,calcium is important for healthy bones and teeth,but your genes,how much vitamin D you take in and getting an hour's worth of exercise every day all play a part.
Some nutritionists disagree with the idea that milk isn't important.Keri Gans,a dietitian,says,"I think it's irresponsible to take away this beverage that children enjoy,especially among those who are unable to meet their nutrient needs for the day,and remove it from the lunch line."
The U.S.government is studying the request of the PCRM,but a decision may be a long way off.Meanwhile,Marion Nestle,a professor at New York University,puts it best:"Milk has nutrients.Other foods have the same nutrients.It's just a food.Like other foods,too much might be a problem."

41.Why does the US government ask students to drink one cup of milk at lunch timeD?
A.They have been told many times.
B.They have taken the PCRM's advice.
C.Fat-free or low-fat milk is less expensive.
D.Milk helps build students'strong bones.
42.Which of the following opinions does the PCRM supportA?
A.Milk is harmful to students'health.
B.Students should drink more milk each day.
C.Orange juice is higher in calcium than milk.
D.Milk is the best way to get calcium.
43.The underlined word"beverage"in Paragraph 4most probably meansC.
A.gene  
B.idea  
C.Milk  
D.Lunch
44.What can we learn from Marion Nestle's words?B
A.Milk has more nutrients than other food.
B.Milk is just a kind of common food.
C.Other food also contains much calcium.
D.Too much nutrient lies in other food.
45.What does the above text mainly talk aboutD?
A.The best way to get the most calcium.
B.The connection between milk and health.
C.Different opinion about the important of milk.
D.Whether to take milk off the school-lunch menu.
2.Scientists investigated why Ebola virus is so deadly when it spreads from animals to humans and then from human-to-human contact.The research team looked at the Zaire Ebola virus in an animal system to understand how it gains strength.This virus is responsible for the current outbreak in West Africa.They found that initially the animal systems were not affected by the virus,but succeeding transmission(传送) into other animals caused the virus to"hot up"and become more severe.
The team analyzed the viruses at different stages and were able to identify several changes in its genetic material that were associated with increased disease.
Professor Julian Hiscox,who led the study from the University's Institute of Infection and Global Health,explains:"The work tells us that the evolutionary goal of Ebola virus is to become more fatal."
"We were able to show through genetic analysis which parts of the virus are involved in this process.The information we have gathered will now allow us to monitor for such changes in an outbreak as well as develop future treatment strategies."
Professor Roger Hewson,leading the study from Public Health England,Porton Down,said:"Ebola virus is such a destructive infection to the people affected by the disease and the economy of West Africa."
"Our understanding of Ebola virus biology is way behind that of other viruses and our cooperation shows how we can bring together our specialists'skills to close this knowledge gap."
Professor Miles Carroll,a co-author of the work,said:"This study has allowed the team to be at the forefront of developing methodologies to analyze patient samples recently taken by the European Mobile Laboratory from West Africa to understand disease evolution during the current outbreak."
29.What does the first paragraph mainly tell us?C
A.How severe Ebola virus is.
B.How Ebola virus spreads.
C.How Ebola virus gradually becomes deadly.
D.What contributions scientists have made on Ebola virus.
30.Which of the following statements is mentioned in the passage?B
A.In the first stage,the virus hurts its victims much.

19.Th 115 m Christmas Bird Count is officially underway.The count is an annual investigation of local and migratory(迁徙的)birds and it's orgnized by the National Audubon Society.From  December 14to January 5,volunteers will gather in more than 2,000locations in North,Central and South America to count the birds in their area.
Each count takes place in a circle about 24kilometers wide.The volunteers follow specific routes within the circle and record the number of individual birds and the different species they see there in a single day.The results are sent to the National Audubon Society and later published on Audubon's Christmas Bird Count website.The data collected during the bird count is a key source Of information for ornithologists,scientists who study birds.
This information is used to develop conservation programs to protect bird habitats and the environment/n general.Data frm the bird count was also used to determine that three species-the Western screech owl,the rusty blackbird and the Newfoundland red crossbill-should be added to Canada's list of species at risk.
The annual bird count was created to protest another Christmas tradition at the very beginning.in the United States in the 19th century,people would often hold"side hunts"on Christmas Day.
Teams of hunters would compete to see who could kill the most birds or other animals that day.In  December 1900,Frank Chapman,an American ornithologist,suggested that instead of hunting birds,people should count them.
Twenty-seven people in 25locations joined in the first Christmas bird count Last year,more than 70,000volunteers took part.This year,counts are scheduled to take place in 17countries,ranging from the Arctic to the Antarctic,with most located in Canada and the United States.instead of taking place only on Christmas day,counts are now held on different days for different areas.

25.How long will the 115th Christmas Bird Count last?A
A.About 3weeks.  B A single day.  C.About a month.  D.About 2weeks.
26.What can we know about the Christmas Bird Count from the passage?C
A.It was organized monthly by the National Audubon Society.
B.It was launched by Frank Chapman,a Canadian ornithologist.
C.Its results can be seen on Audubon's Christmas Bird Count website.
D.Only 25people in 27locations took part in the first Christmas Bird Count.
27.Why was the Christmas Bird Count established at first?B
A.To help the scientists who study birds carry out their study.
B To protest the Christmas tradition"side hunts"on Christmas Day.
C.To determine whether the rusty blackbirds are endangered animals.
D To protect bird habitats and the environment from being destroyed
28.What is mainly talked about in Paragraph 5?D
A.The brief introduction to the Christmas Bird Count
B.The origin of the Christmas Bird Count.
C.The purpose of the Christmas Bird Count.
