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.

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?

7.Cooking programs and classes for children seem to positively influence children's food preferences and behaviors,according to a recent review.And,although the review didn't look at long-term effects of such programs,the findings suggest that such programs might help children develop long-lasting healthy habits.
This research comes at a time when childhood obesity(肥胖) rates have been rising rapidly.More than one-third of adolescents in the United States were obese in 2012,according to the U.S.Centers for Disease Control and Prevention (CDC).This trend has been caused,at least in part,by a significant decrease in the amount of meals that people consume at home since the 1980s,according to background information in the study.
Cooking education programs,such as Food Explorers,teach children about new healthy foods and how to prepare them.They also stress the importance of eating five fruits and vegetables every day.A volunteer parent explains a new food to the group,and the kids make something based on the lesson,such as fruit or vegetable salad.Depending on the program,kids may be sent home with information about healthy foods to bring to their parents,the review explained.
The study team reviewed eight other studies that tested different types of cooking education programs.Children in these classes were between 5and 12years old,according to the review.The goal of the study team was to learn more about developing an efficient program to encourage healthy food choices that last a lifetime.The study found that it is particularly important to expose kids to healthy foods on a number of occasions.This makes them feel comfortable with the new foods,which helps them build healthy habits.
The study stressed the importance of getting parents involved in(参与) their children's eating habits.Parents who are unable to enroll their kids in a cooking class can achieve similar benefits by having their kids help them while they prepare meals at home.Children are more comfortable at home,which makes them more receptive to new foods because they will make the connection to a positive experience.

36.What can we infer from the second paragraph?A
A.Eating out frequently causes obesity.
B.Childhood obesity is totally caused by eating habit.
C.Childhood obesity rates have been rising rapidly since 2012
D.Food consumption has decreased significantly since the 1980s.
37.On cooking education programs,C.
A.children learn how to prepare foods from their parents
B.children will learn how to cook in the company of their parents
C.children may learn information unknown to their parents
D.children focus more on cooking skills than on information about healthy foods
38.Which of the following is true according to the study?B
A.Parents should let their kids cook independently at home.
B.A greater willingness to try new foods helps building healthy habits.
C.Children who participate in cooking programs are less likely to become obese.
D.Children who take cooking courses are more likely to choose fruits and vegetables as adults.
39.Which of the following categories does this passage belong to?D
A.Education Systems
B.Science and Technology
C.Parent-child Relationship
D.Public Health Research
40.The purpose of the passage isA.
A.to inform the reader
B.to entertain the reader
C.to discuss with the reader
D.to warn the reader.

14."Clean your plate!"and"Be a member of the clean-plate-club!"Just about every kid in the US has heard this from a parent or grandparent.Often,it's accompanied by an appeal:"Just think about those starving orphans in Africa!"Sure,we should be grateful for every bite of food.Unfortunately,many people in the US take too many bites.Instead of staying"clean the plate",perhaps we should save some food for tomorrow.
According to news reports,US restaurants are partly to blame for the growing bellies.A waiter puts a plate of food in front of each customer,with two to four times the amount recommended by the government,according to a USA Today story.Americans traditionally associate quantity with value and most restaurants try to give them that.They prefer to have customers complain about too much food rather than too little.
Barbara Rolls,a nutrition professor at Pennsylvania State University,told USA Today that restaurant portion sizes began to grow in the 1970s,the same time that the American waistline began to expand.
Health experts have tried to get many restaurants to serve smaller portions.Now,apparently,some customers are calling for this too.The restaurant industry trade magazine QSR reported last month that 57percent of more than 4,000people surveyed believe restaurants serve portions that are too large; 23percent had no opinion; 20percent disagreed.But a closer look at the survey indicates that many Americans who can't afford fine dining still prefer large portions.Seventy percent of those earning at least 150,000peryearprefersmallerportions;butonly45percentofthoseearninglessthan25,000want smaller.
It's not that working class Americans don't want to eat healthy.It's just that,after long hours at low-paying jobs,getting less on their plate hardly seems like a good deal.They live from paycheck to paycheck,happy to save a little money for next year's Christmas presents.

36.Parents in the United States tend to ask their childrenD.
A.to save food.
B.to wash the dishes.
C.not to eat too much     
D.not to waste food.
37.Why do American restaurants serve large portions?B
A.Because Americans have big bellies.
B.Because Americans associate quantity with value.
C Because Americans are good eaters.
D.Because Americans are greedy.
38.What happened in the 1970s?C
A.The US government recommended the amount of food a restaurant gave to a customer.
B.Health experts persuaded restaurants to serve smaller portions.
C.The American waistline started to expand.
D.The United States produced more grain than needed.
39.What does the survey indicate?B
A.Twenty percent Americans want smaller portions.
B.Many poor Americans want large portions.
C.Fifty seven percent Americans earn 150,000peryear.
D.TwentythreepercentAmericansearnlessthan25,000per year.
40.Which of the following is Not true of working class Americans?D
A.They work long hours.
B.They live from paycheck to paycheck.
C.They want to save money for their children

4.The Ebola Virus
Currently,the world is facing an epidemic (流行病) due to what is considered to be among the most dangerous viruses that humanity has ever faced-the Ebola bleeding virus.Though there were announcements about experimental treatments that were reported to be successful in terms of treating the virus,people around the world continue to die from Ebola.
Ebola was first discovered in 1976in Africa,on the banks of the Ebola River,after which the virus has been named.Back then,there were two major outbreaks of the virus,and this is how people learned about it.There exist several strains of the Ebola virus,some of them are deadly to people,and some are not.
The main symptoms of Ebola can appear in a period between the second and the 21st days of infection,but usually it happens on the eighth through 10th day.Among the symptoms that appear in the first turn,one should mention fever and chills,strong headaches,pain in joints and muscles,and general weakness.These symptoms are not too different from those that people usually experience when catching a severe cold,or flu,so victims may even ignore these symptoms,or try to treat them as a common sickness.However,as the virus keeps progressing,a patient develops nausea(呕吐) with vomiting,diarrhea,chest and stomach pains,red eyes and rash over the body,severe weight loss,and bleeding from almost all bodily openings.
The virus is usually transmitted either through blood,or through waste.Infection through blood usually takes place if a person consumes infested meat,or even touches it (for example,butchering can also lead to infection).Also,there were cases when people got infected after stepping in waste of infected mammals,mostly bats.The other ways of getting infected is through skin by receiving bodily liquids via tiny openings.
Even though there is no specific cure for Ebola,doctors still try to treat it.In order to diagnose Ebola,doctors usually take tests on such diseases as cholera or malaria,because it is difficult to diagnose Ebola based only on symptoms.After the diagnosis has been made,doctors start treating the symptoms,which includes killing infected cells,electrolytes,blood pressure medication,blood transfusions,oxygen treatment,and so on.
Though Ebola is a highly dangerous disease,it is not likely that it will spread globally.It is most deadly in anti-sanitary(不卫生的) conditions,which many African countries have an extremely bad reputation for.As for first world countries,even though there is still no universal cure,they are at much lesser risk than African countries.Though the symptoms of Ebola are severe and getting infected is not difficult,with the correct handling of an outbreak,the virus should not be able to spread.


(71)Introduction
●Ebola,a dangerous virus,was named after the Ebola River,on whose banks it was first discovered.
●Despite the (72)announced/reported success in the virus treatment,people across the world continue to die from the virus.

Symptoms
●In the first turn,the symptoms are (73)similar to those that people experience when they are (74)suffering from a severe cold or flu.
●If not (75)taken seriously,the virus will keep progressing,and things will change for the worse.

Ways of getting infected
●People (76)consuming infested meat or touching it can get infected.
●People who step in waste of infected mammals,mostly bats,are (77)likely to get infected.
●People who receive bodily liquids via tiny openings can also get infected.

Treatment and  (78)prevention
●After making correct diagnosis,doctors start treating the symptoms in many ways,(79)including killing infected cells,blood pressure medication,oxygen therapy,and so on.
●Sanitary living conditions play a significant (80)part/role in preventing the outbreak of the Ebola virus.

11.What would you do to reduce the chance of dying of cancer?How far would you go if you had a 70to 90percent chance of contracting bowel--and your uncle,mother,father,and two of your brothers had died from it?
Lynne Fisher decided she would do almost anything.So,even though she showed no signs of cancer at all,Fisher,51,a former mental health worker,agreed to undergo what might sound like a radical surgery:doctors removed nearly her whole colon(结肠) and rerouted her small intestine(肠) to perform the functions of her large intestine.
The side effects were horrific,she said.For a year,Fisher struggled to control her bowel movements.She fought depression,and she hated her large scars and the 28staples that had been left in her body.Her Multiple Sclerosis returned.The woman she shared a hospital room with--who'd had a similar surgery--did not survive.
"When you're in it,it's like a dark tunnel,"she told ABC News in a long phone conversation about her medical history.
But then,one day,she realized the surgery had helped saved her life.And since then,she's never looked back.
"What's a year out of your life compared to dying?"  the 51-year-old said from her home in central England."I get to watch my dogs grow up,my children grow up,my grandchild,I get to see my cherry blossoms in the tree,I get to see the sun shining in the morning,I get to go on holiday--I get to see life."
Genes that cause breast cancer have been discussed widely for years.But less well known is Lynch syndrome,the gene mutation that Fisher and her much of her family inherited.
Roughly one in 370people has Lynch syndrome,according to Lynch Syndrome International,an organization dedicated to helping people with Lynch syndrome and those who treat them.It's unclear how many Americans choose to have the surgery that Fisher had:prophylactic subtotal colectomy,which doctors describe as a major surgery that,while elective,can often save lives.

36.Why did Lynne Fisher decide to remove nearly her whole colon?C
A.Because she has already had a cancer.
B.Because she thought the colon was useless.
C.Because she was afraid of dying of bowel cancer someday.
D.Because her doctor persuaded her to do that.
37.According to the passage,what is NOT true about the surgery undergone by Lynne Fisher?A
A.It is only a very simple and easy surgery.
B.It can bring about some terrible side effects.
C.It's possible for one to die of the surgery.
D.It takes one maybe a year to recover from the surgery.
38.What can we learn from the underlined sentence?C
A.Lynne Fisher really regretted what she had done.
B.Lynne Fisher thought it was not worth a year to have the surgery.
C.Compared to death,the suffering during the year was worthwhile.
D.Lynne Fisher spent a painful year in recovering from the surgery.
39.What can we learn from the last paragraph?A
A.About 0.27% people have Lynch syndrome now in America.
B.We can tell exactly how many people have had the surgery.

8.Plastic bags that can help bread and cheese remain fresh for a long time have been developed by scientists.The technology,which uses chemicals that prevent bacteria and fungi (真霉) from growing,allows food to last longer.It could put an end to throwing away supermarket bread after just a couple of days in the bread bin and cheese that goes mouldy after just a few weeks.
The company,Janssen,has spent two years developing the technology with the plastics manufacturer,Symphony Environmental.They are now in discussion with several food factories and supermarkets about using the bags for their products.The technology could also be used to make credit cards and the new plastic bank notes more hygienic (卫生的).Tests have shown that the plastic can increase the shelf life of bread and cheese without letting the food go bad.Michael Stephen,director of Symphony Environmental,said the plastic also has the potential to do the same for fruit,vegetables and even meat.He said,"we have come up with a way of making the plastic that is antibacterial and that can be used in food wrapping.We have done a lot of tests on food packaging which have shown such plastic can reduce the mould that grows on both bread and cheese."
In Britain,around 15 million tons of food is thrown away each year,mostly because it has spoiled or gone bad.Bread is the most wasted food,with families throwing away 4.4 million tons a year-about a third of all the bread purchased by UK families.Tesco,Britain's biggest supermarket,revealed last month that almost half of the bread sold in its stores ended up in the bin.
The technology developed by Janssen and Symphony,which they have called D2P,fixes antibacterial and antifungal chemicals to the plastic.They have found it can control bacteria which can cause food poisoning.It can also control the growth of fungi on bread and others.
Mr.Stephen added,"Initially we expect that it is only used in pipes and door handles,for example,to help reduce the spread of bacteria.It can also be put into man-made fibers so we are doing some experiments to put it into clothes to stop the bacteria that can cause them to smell."
59.What would happen when people use the plastic bags produced by Janssen?C
A.The sales of bread and cheese would increase soon.
B.Bread and cheese could be stored in a fridge for years.
C.Bread and cheese could be kept for a longer time.
D.Supermarket bread and cheese would be on sale earlier.
60.Why does the writer mention the problem in Britain in Paragraph 3?D
A.To criticize the behaviour of the British.
B.To show the popularity of bread.
C.To criticize the increasing waste of bread.
D.To show the short shelf life of bread.
61.It can be concluded from Mr.Stephen's words thatA.
A.more daily uses for this technology are expected
B.this technology is only used used in pipes and door handles
C.man-made fibers should be improved by this technology
D.people's preference for this technology cannot be expected
62.The passage can be classified asB.
A.an annual review                B.a news report
C.an advertisement                D.a travel guide.

1.The hit movie Finding Nemo follows a clownfish from the Great Barrier Reef. In real life,clownfish are among the thousands of colorful sea creatures that call the Great Barrier Reef home.Stretching l,250 miles along Australia's northeastern. coast,the Great Barrier Reef is the longest coral reef in the world.
    A coral reef is a living underwater structure. But these days,the Great Barrier Reef has found itself in trouble.Overfishing,pollution,and high temperatures are harming its health. That's why the government in Australia is trying to help rescue the reef.
Underwater Garden
   While coral may look like a plant,it is actually made up of tiny sea animal.Those sea animals are called coral polyps. 
   As polyps die,they leave hard.shells behind. Other polyps grow on top of the shells.Over thousands of years,they form a coral reef in warm water that is not very deep.
   In many ways,the Great Barrier Reef resembles an underwater garden.  Coral can be hard or soft.It forms in different colors and in strange shapes.Some coral looks like hardened brains. Other coral looks like fans and lettuces.
  The reef bursts with schools of tropical fish,dashing among gaps in the coral.The reef supplies food. and. shelter to creatures living in and around the coral.  Turtles,sharks,sea horses,and crabs are among its many inhabitants.
Helping Humans
     While the reef is important to ocean life,it helps humans,too.  People rely on the reef for both food and jobs. It also provides medicine used to treat disease.  Each year,the Great Barrier Reef contributes about  $ 975 million to the economy through tourism and fishing.
Stressed Out   
    Is it surprising,then,that the Great Barrier Reef is under too much stress?Fishing nets and ships break off sections and damage the reef.  Air and water pollution are also doing harm. At the same time,warmer sea temperatures have caused coral bleaching(漂白) on half of the reef. The high temperatures cause the coral to turn white,often killing it.
Reef Rescue
    In an effort to help save the reef,the government has limited fishing to two thirds of it. That plan increases the number of"green zones."Those are areas that are off-limits to fishermen and boats. However,tourists and researchers can still visit them. Many fishermen are upset about the plan because they rely on the reef for jobs.
     The Australian government says that its plan will help keep the reef safe from some threats."It is very important that we give   B reef proper protection for the future,"said one government official.  The reef is Australia's greatest natural treasure.

35.Which of the following is not a creature that lives in the Great Barrier Reef?D
A.  Coral polyps. 
B. Turtles.       
C.  Sea horses.  
D. Whales.
36. Which section describes the problem in this passage?C
A."Underwater Garden"
B."Helping Humans
C."Stressed Out"
D."Reef Rescue"
37.What picture can the reader get from the underlined sentence"The reef bursts with schools of tropical fish,dashing among gaps in the coral."in Paragraph 6?C
A. Many fish quickly moving through the coral.
B.  Fish moving toward the center,or target,of the coral.
C.  Structured,orderly groups of young fish without a clear path. 
D. Fish exploding when they come into contact with gaps in the coral.
38.What is this passage mostly about?A
A. The causes of reef problems an  possible solutions.
B. Coral bleaching,which causes the reef to turn white.
C. The history of tourism to the Great Barrier Reef.
D. Overfishing and higher temperatures.
