15.Since the beginning of the year,smog has covered parts of North China.In January,Beijing saw only five days without smog.The rising PM 2.5readings terrified many people,and some health experts said that whenever the smog gets serious,hospitals receive more patients suffering acute respiratory(呼吸系统)and heart diseases.
Later,news of polluted underground water in some provinces scared people who wondered whether the water they drink is safe.
So the need to emphasize environmental protection while developing the economy is heard everywhere.
Smog especially is a common concern.Like a popular online post said,air may be the only thing that is equal for everyone,despite your income or vocation.People with higher incomes are able to drink only bottled spring water and eat only organic food by paying higher prices,but they breathe the same air as everyone else.
At a meeting on Monday,many Representatives have expressed their concerns about the air quality,too.One talked about his experience in Beijing."After taking a taxi from the capital airport to my hotel,which took about an hour,I washed my nose and found the inside of my nose was black.We should ask ourselves this question:Why do we want to develop?It's for living a better life.Dirty air is definitely not a better life,"he said.
China needs to develop its economy and invest(投资) in high-tech.Every Chinese wants a strong country.But without blue sky,clean water and safe food,the achievements in the economy will become meaningless.Space technologies are not to be developed for building a base on Mars so that one day all human beings can migrate to the red planet because  they have destroyed Earth.
What the public wants is a strong and beautiful China.Former president Hu Jintao spoke at the 18th Party Congress last November saying that great efforts must be made to promote ecological progress and build a beautiful China.The words have shown the central government's resolution to address the environment issue.

36.The effect of smog doesn't include.C
A.the rising of PM 2.5readings
B.more people suffering diseases
C.the increase of people's income
D.patients increased in hospital
37.Why smog has become a common concern?B
A.Because people have to pay higher prices.
B.Because nobody can avoid it.
C.Because we have to develop industry.
D.Because a popular online-post discussed it.
38.The underlined word"they"in paragraph 6refers to.A
A.human beings         B.other plants
C.space technologies   D.industrial development
39.From the last two paragraphs we can infer that.D
A.high-tech can completely solve the problem of pollution
B.space technologies should be developed in a large scale
C.we can move to the Mars after the earth has been destroyed
D.we must protect the environment while developing economy.

6.At the U.S.Open championships in Flushing Meadows,New York last week,the United States Tennis Association (USTA) held an unusual youth press conference (新闻发布会).I say"unusual"because the main idea wasn't to promote the sport for young children.Yes,there was a youth tennis exhibition in which a group of fresh-faced kids from the area showed off their well developed skills.They used junior racquets and larger,low-pressure balls on a half-size tennis court-a way the organization supports as a means to help children have early success and stick with the game.
But the event's real purpose was to help parents realize the importance of introducing kids to all kinds of athletic programs rather than focusing specially on one. This may sound like something easy to do,but it's not.In today's achievement-oriented (成功向导 ) environment,children are being pushed to specialize in a single sport-whether it's tennis,hockey,soccer,or gymnastics-at ever-younger ages.Tom Farrey,executive director of the nonprofit Aspen Institute Sports & Society Program,says year-round sports programs are now offered down to age 5,too early an age for a child to limit himself or herself to a single activity.While parents naturally want the best for their child,they are being pressured by coaches to let him or her stick with one thing.
The result:More kids under age 12are suffering injuries or,worse,burnout.According to the Aspen Institute's report,Project Play,fewer kids today are staying involved with sports than five years ago,partly because of forced specialization.Today's children are already on track to live shorter,less healthy lives than their parents because of obesity and related diseases,and this trend is only worsening matters.
Multi-sport participation,however,leads to better performance (because kids get a chance to develop different sets of skills ) and greater enjoyment of the game,says Farrey.The headlining athletes at the event repeated the idea that having kids do more than one sport is a plus (good for them).
68.According to Tom Farrey,which of the following statements is TRUE?C
A.Having kids do more than one sport is an advantage to their future career.
B.A child should limit himself to a single activity under the age of 5.
C.Parents are being pressured to let their kids stick with one sport.
D.Multi-sport participation leads to most kids'worse performance.
69.The underlined word"this"in paragraph 2refers toA.
A.introducing kids to many different sports instead of only one
B.inviting kids to only one sport instead of trying different ones
C.taking kids to only several different sports instead of too many
D.leading kids to any sport they like instead of trying many kinds
70.Fewer kids are staying involved with sports now than five years ago partly because theyD.
A.become too fat to take part in sports
B.have too much school work to complete
C.get too many injuries when they do sports
D.are pushed into specialized sport too hard
71.What's the best title for the passage?C
A.The Importance of Doing Sports          
B.The Necessity of Physical Education
C.Stop Specializing in Sports So Early        
D.Develop Children's Athletic Abilities.
3.Malaria,the world's most widespread parasitic (寄生虫引起的)disease,kills as many as three million people every year-almost all of whom are under five,very poor,and African.In most years,more than five hundred million cases of illness result from the disease,although exact numbers are difficult to assess because many people don't (or can't) seek care.It is not unusual for a family earning less than two hundred dollars a year to spend a quarter of its income on malaria treatment,and what they often get no longer works.In countries like Tanzania,Mozambique,and the Gambia,no family,village,hospital,or workplace can remain unaffected for long.
Malaria starts suddenly,with violent chills,which are soon followed by an intense fever and,often,headaches.As the parasites multiply,they take over the entire body.Malaria parasites live by eating the red blood cells they infect.They can also attach themselves to blood vessels in the brain.If it doesn't kill you,malaria can happen again and again for years.The disease is passed on to humans by female mosquitoes infected with one of four species of a parasite.Together,the mosquito and the parasite are the most deadly couple in the history of the earth and one of the most successful.Malaria has five thousand genes,and its ability to change rapidly to defend itself and resist new drugs has made it nearly impossible to control.Studies show that mosquitoes are passing on the virus more frequently,and there are more outbreaks in cities with large populations.Some of the disease's spread is due to global warming.
For decades,the first-choice treatment for malaria parasites in Africa has been chloroquine,a chemical which is very cheap and easy to make.Unfortunately,in most parts of the world,malaria parasites have become resistant to it.Successful alternatives that help prevent resistance are already available,but they have been in short supply and are very expensive.If these drugs should fail,nobody knows what would come next.

67.According to paragraph 1,many people don't seek care becauseA.
A.they are too poor
B.it is unusual to seek care
C.they can remain unaffected for long
D.there are too many people suffering from the disease
68.People suffering from malariaC.
A.have to kill female mosquitoes
B.have ability to defend parasites
C.have their red blood cells infected
D.have sudden fever,followed by chills
69.Which of the following may be the reason for the wide spread of the disease?D
A.Its resistance to global warming.
B.Its ability to pass on the virus frequently.
C.Its outbreaks in cities with large populations.
D.Its ability to defend itself and resist new drugs.
70.It can be inferred from the passage thatB.
A.no drugs have been found to treat the disease
B.the alternative treatment is not easily available to most people
C.malaria has developed its ability to resist parasites
D.nobody knows what will be the drug to treat the disease.
10.The word"conservation"has a thrifty meaning.To conserve is to save and protect,to leave what we ourselves enjoy in such a good condition that others may also share the enjoyment.Our forefathers had no idea that human population would increase faster than the supplies of raw materials:most of them,even until very recently,had the foolish idea that the treasures were"limitless"and could"last forever".Most of the citizens of earlier generations knew little or nothing about the complicated and delicate system that runs all through nature,and which means that,as in a living body,an unhealthy condition of one part will sooner or later be harmful to all the others.
Fifty years ago,nature study was not part of the school work; scientific forestry was a new idea; wood was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river floods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper land use; even the word"conservation"had nothing of the meaning that it has for us today.
For the sake of ourselves and those who will come after us,we must now set about correcting the mistakes of our forefathers.Conservation should be made part of everybody's daily life.To know about the water table in ground is just as important to us as a knowledge of the basic math formulas.We need to know why all watersheds (上游集水区) need the protection of plant life and why the running current of streams and rivers must be made to give their full benefit to the soil before they finally escape to the sea.We need to be taught the duty of planting trees as well as of cutting them.We need to know the importance of big,grown trees,because  living space for most of man's fellow creatures on this planet is figured not only in square measure of surface but also in cubic (立方体的) volume above the earth.In a word,it should be our goal to restore as much of the original beauty of nature as we can.

63.The author's attitude towards the use of natural resources isD.
A.positive     B.uninterested    C.optimistic    D.critical
64.According to the author,the greatest mistake of our forefathers was thatB.
A.they had no idea about scientific forestry
B.they had little or no sense of environmental protection
C.they were not aware of the importance of nature study
D.they had no idea of how to make good use of raw materials
65.To avoid repeating the mistakes of our forefathers,the author suggests thatC.
A.we plant more trees
B.natural sciences be taught to everybody
C.environmental education be directed toward everyone
D.we return to nature
66.How can you understand the underlined sentence in the last paragraph?D
A.Our living space on the earth is getting smaller and smaller.
B.Our living space should be measured in cubic volume.
C.We need to take some measures to protect space.
D.We must preserve good living conditions for both birds and animals.
20.Organic food,once considered something that only health fanatics desired,is now a regular feature at most supermarkets.And that has created a bit of a dilemma.On the one hand,you have a conventionally grown apple.On the other,you have one that's organic.Both apples are firm,shiny and red.Both provide vitamins and fiber,and both are free of fat,sodium and cholesterol.
Conventionally grown food generally costs less,but is organic food a better choice?The advantages claimed for such foods over conventionally grown and sold food products are now being debated on a large scale.Supporters of organic foods-a term whose meaning varies greatly-are frequently telling the world that such products are safer and more nutritious than others.
The growing interest of consumers in the safety and nutritional quality of daily foods is a welcome development.However,much of this interest has been aroused by sweeping claims that the conventional food supply is unsafe or inadequate in meeting nutritional needs.
Almost daily,the public is surrounded by claims for"no-aging"diets,new vitamins and other wonder foods.There are numerous unsubstantiated(没证实的) reports that natural vitamins are superior to man-made ones,that fertilized eggs are nutritionally superior to unfertilized eggs,that untreated grains are better than those treated with insect spray and the like.
Although most of these claims are not supported by scientific evidence,large amounts of written material about the benefits of organic foods makes it difficult for people to separate fact from fiction.As a result,claims that eating a diet consisting of organically grown foods prevents or cures disease or provides other benefits to health have become widely advertised and form the basis for people's opinion.
One thing that most organically grown food products seem to have in common is that they cost more than conventionally grown foods.But in many cases consumers are misled if they believe organic foods can maintain health and provide better nutritional quality than conventionally grown foods.So there is real cause for concern if consumers,particularly those with limited incomes,distrust the conventional food supply and buy only expensive organic foods instead.
41.According to Paragraph 2,which of the following statements about organic food is true?B
A.It hasn't been used until recent years
B.It has no agreed definition.
C.It is popular among producers
D.It is accepted by most nutritionists.
42.In Paragraph 4,treated grains are examples ofC.
A.healthier food                         
B.organic food             
C.conventionally grown food               
D.expensive food           
43.It can be inferred from the passage thatD.
A.most doctors believe organic foods prevent disease or provide other benefits to health
B.organic foods are actually less nutritious than conventionally grown foods
C.people cannot separate fact from fiction because of the TV advertisements
D.organic foods cost more but are not necessarily better than conventionally grown foods
44.According to the passage,many consumers are attracted by organic foods because theyC
A.want to try something new               
B.have carefully researched the products
C.value food safety and nutrition             
D.expect to save some money
45.What is the author's attitude towards the claims of organic foods?A
A.Doubtful.B.Enthusiastic.C.Supportive.D.Uninterested.
4.Sports medicine experts have observed for  years that athletes such as long distance runners,especially women athletes,often display a lack of iron.Now a new study by a team of Purdue University researchers suggests that even moderate exercise may lead to reduced iron in the blood of women.
"We found that women who were normally inactive and then started a program of moderate exercise of middle degree showed sings of iron loss,"says Roseanne M.Lyle,associate professor at Purdue.Her study of 62formerly inactive women who began exercising three times a week for six months was published in the journal Medicine & Science in Sports & Exercise.Iron deficiency is very common among women in general,affecting one in four female teenagers and one in five women aged 18to 45,respectively.But the ratio is even greater among active women,affecting up to 80percent of female endurance athletes.This means,Lyle says,that"too many women ignore the amount of iron they take in".Women of child-bearing age are at greatest risk,since their monthly bleeding is a major source of iron loss.Plus,many health-conscious women increase their risk by rejecting red meat,which contains the most easily absorbed form of iron.And because women often restrict their diet in an effort to control weight,they may not consume enough iron-rich food,and are liable to experience a deficiency.
Exercise can result in iron loss through a variety of mechanisms.Some iron is lost in sweat,and,for unknown reasons,intense endurance exercise is sometimes associated with bleeding of the digestive system.Athletes in high-impact sports such as running may also lose iron through a phenomenon where small blood vessels in the feet leak blood.
There are three stages of iron deficiency.The first and most common is having low iron reserves,a condition that typically has no symptoms.Fatigue and poor performance may begin to appear in the second stage of deficiency,when not enough iron is present to form the molecules(分子) of blood protein that transport oxygen to the working muscles.In the third and final stage,people often feel weak,tired,and out of breath-and exercise performance is severely compromised.
"People think that if they're not at the third stage,nothing is wrong,but that's not true,"says John L.Beard,who helped design the Purdue study."You're not stage 3until your iron reserves go to zero,and if you wait until that point,you're in trouble."
Beard and other experts say it's advisable for people to have a yearly blood test.If iron levels are low,talk with a physician to see if the deficiency should be corrected by changing your diet and taking iron-rich foods or by taking iron-added pills.
"Select breads and cereals with the words‘iron-added'on the label,"writes sports diet expert Nancy Clark."This added iron supplements the small amount that naturally occurs in grains."Clark also recommends cooking in iron pans,as food can obtain iron from the pan during the cooking process.

64.Which of the following may be the title for the passage?C
A.Science,sports and exercise
B.Correct iron deficiency
C.Women,Iron and exercise
D.Women,health and exercise

B.presenting the result followed by specific causes
C.beginnign with details followed by a general statement
D.making comparisons ad contrasts
66.What does it mean when you are in the third stage of iron defieiency?D
A.Nothing serious though you don't have much iron stored in the body.
B.There is not enough iron to form the molecules of blood protein to transport oxygen.
C.The small blood vessels in your reet are beginnig to leak blood.
D.No iron is ldft in your body and you would be in trouble without urgent measures.
