18.Smoggy weather has become common in China.But these days,air pollution levels in the north eastern city of Harbin surpassed the previous record levels.
The city was essentially shut down after PM2.5,fine Particulate(微粒物) pollution that is considered hazardous(有害的).reached levels of 1000micrograms per cubic meter-40times the safety level remended by the World Health Organization.Schools,motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10meters.
Photos from Harbin showed residents covering their mouths with masks and scarves,and moving like ghostly shadows through the fog.Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible..
Just days previously,the World Health Organization's International Agency for Research on Cancer (IARC)  classified air pollution as a carcinogen(致癌物).It stated that there  is"sufficient evidence"that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer.It's said that exposure has increased significantly particularly in"rapidly industrial countries with large populations".
"The air we breathe has become polluted with a mixture of cancer-causing substances",Dr Kurt Straif,head of the IARC said in a press released."We now know that outdoor air pollution is not only a major risk to health in general,but also a leading environmental cause of cancer deaths."
On the Chinese social media site Weibo,many users complained about the pollution and shared their concerns.References to"feed people with smog"have become popular on Weibo and there is a sarcastic play on the expression"serve the people",as the two have a similar pronunciation.
"The impact of air pollution on people will be gradual.There won't be a sudden outbreak of symptoms,but normally three to five days after the smoggy weather occurs,there is a peak in the number of people seeing doctors,"Deng Ying,a doctor at the Second Affiliated Hospital of Harbin Medical University was quoted as saying.

24.As thick smog has become a common scene in Harbin,D
A.students there can go to school as usual
B.residents in the city can see as far as 20meters
C.traffic lights can be easily visible
D.the urban traffic has been seriously influenced
25.When exposed to outdoor air pollution,what kind of disease can be caused?C.
A.Cancer of stomach  B.Breast cancer  C.Bladder cancer     D.Ovarian cancer

分析 文章描述了哈尔滨PM2.5超标,能见度不到10米.空气污染不仅给人们出行带来不便,还会对人类的健康造成影响,特别会导致一些诸如肺癌,膀胱癌的发生.提醒人们不仅仅是注重饮食来防霾,更重要的是要加强环境保护的意识.

解答 24.D 细节理解题.根据文章2,3段中的Cars and motorcycles are moving slowly as traffic came to a standstill with traffic lights barely visible和Schools,motorways and an airport were closed on Tuesday as visibility in some areas of the city dropped to less than 10meters可知由于PM2.5(直径小于2.5微米的微小颗粒)浓度太高,导致能见度降低,车辆无法迅速行驶,造成交通堵塞.故D正确.
25.C  细节理解题.根据第4段It stated that there  is"sufficient evidence"that exposure to outdoor air pollution causes lung cancer and also linked it with an increased risk of bladder cancer.可知,有足够的证据显示,肺癌以及膀胱癌的发生与接触污染的空气有关.故C正确.
26.B  推理判断题.根据文章第五段"The air we breathe has become polluted with a mixture of cancer-causing substances",Dr Kurt Straif,head of the IARC said in a press released."We now know that outdoor air pollution is not only a major risk to health in general,but also a leading environmental cause of cancer deaths."可知Dr Kurt Straif认为空气污染不仅仅是健康的一大威胁,也是一个导致癌症死亡的主要环境因素.故B正确.
27.A  推理判断题.作者在本文中详细描述了哈尔滨PM2.5超标,说明了空气污染对于人类健康的影响,特别会导致一些诸如肺癌,膀胱癌的发生.目的在于提高人们对于环境保护的意识.故A正确.

8.Emergency rooms (ER) are supposed to cure people but Dr.John Stemgold wonders if working in an ER in Willits made him sick.The ER was downwind of the Remco chrome plant."I used to sit facing that window and kind of daydream out the window,looking at Remco,looking at the fog coming out of there.Then I would cough and cough."Stemgold said.
What Dr.Stemgold didn't know was that Remco was flowing out Chromium VI into the air---a chemical known to cause cancer and breathing problems in humans.A recent state health department study found that people who were in Willits when Remco was in operation from 1964to 1995are at higher risk for cancer because of Chromium VI exposure.
Today Dr.Stemgold has lots of time to play his guitar.It turns out he has a form of breathing difficulty.Hospital chemicals cause coughing so violently that he's broken bones and it's cost him his career.Others in this town believe the Chromium has made them sick,too,and their families.Actually,Chromium VI was classified as a carcinogen,a cancer-causing substance,thirty years ago,Twenty years ago,a group of state scientific specialists found no exposure level below which carcinogen effects would not have some probability of occurring.Still,Remco was allowed to flow out Chromium VI into the air.
In the battle to balance public health and a healthy economy,laws often favor business,Alan Ramo is a professor of law at Golden Gate University."There is a real drive to make money,to have employment.When there's a real job that's available and a theoretical risk of a chemical,jobs win out,business wins out."
And chemicals are allowed to flood the marketplace and the government requires strict testing before any drugs can be sold.But the vast majority of industrial chemicals are put into use little testing of any kind Chemicals that people like us,you and me might be exposed to.Marilyn Underwood is with California state health department."You need to have the convincing evidence that something is bad to then start regulating it."However,in most cases,chemicals are not tested until someone reports the abnormal,unnatural condition of the environment in general.
"I think that if people really knew what really goes on with environmental protection I think they would be shocked and they should be."Says Professor Ramo."It might be valuable for other people to know what has happened to me,not for me but for them."He said"because they might be in a similar situation because of where they work."
70.What happened to the people who lived in Willits from 1964-1995D?
A.most of them were forced to move away.
B.They earn a lot of fortune from the factory or the profit it brought about.
C.employees from local area all got sick and lost their jobs at the plant.
D.They have a greater chance of having severe disease.

9.For pet owners,the hundreds of pet food recalls taking place each year has raised a lot of alarm."Most people are caring pet owners,and they want to do what helps protect their pet,"explains Will Post,founder and CEO,Hound & Gatos Pet Foods Corporation."Yet the problem is that most are not sure what that means and how to go about it.The more they learn about pet food,the better able they will be to make an informed decision that will keep their pet healthier and safer."
Here are several tips that consumers may want to keep in mind when it comes to choosing a pet food that will help reduce the risks.
Get to know the company.Most people may know a company name simply because they spend millions on advertising.But that doesn't mean they know much about the company or their morals.Research companies to find one that offers high standards,quality products,and great customer service.
Ask questions.Don't be afraid to get in touch with a pet food company and ask them where something was made,where ingredients(原料) came from,or any other questions.They should have no problem answering questions about their products,or with being able to provide proof of their quality standards.
Read reviews.Do some searches to read some reviews about various brands of pet food.Keep in mind that some reviews can be one-sided and even planted by the company itself,so look for fair third-party sources giving the review.
Investigate(调查) ingredients.The source of ingredients is of major concern when it comes to reducing the risks of pet food recalls and keeping pets healthy.Read the labels and ask questions to determine where the ingredients are coming from.
Understand pet foods.Cat and dog food should contain 100percent protein,which will supply them with the nutrients their bodies require.The problem with many commercial pet foods is that it is full of numerous fillers,such as cheap fillers and grains.

36.How can people provide a safer and healthier environment for their pet?B
A.By giving more food to their pet.
B.By getting a better understanding about pet food.
C.By accompanying their pet more.
D.By knowing more about their pet.
37.How many pieces of advice on choosing a pet food are given by the author?C
A.Three.  B.Four.  C.Five.  D.Six.
38.As for reducing the risks of pet food recalls,what should be mainly taken into consideration?A
A.Where the ingredients come from.
B.Whether the company has good reputation.
C.Whether the food supply enough nutrients.
D.Whether most people choose the food.
39.The passage is mainly aboutB.
A.the increasingly serious problem about food safety
B.the ways to choose a safer pet food
C.the opinion about food safety
D.the advice on caring pets
40.Who are the intended readers of the passage?D
A.People in general.
B.Food companies.
C.Pet shop owners.
D.Pet owners.

6.Nowadays,the food we eat seems to have great effects on our health.Although science has made enormous steps in making food more fit to eat,it has,at the same time,made many foods unfit to eat.Some research has shown that perhaps eighty percent of all human illnesses are related to diet and forty percent of cancer is related to the diet as well,especially cancer of the colon.Different cultures are more likely to cause certain different illnesses because of the food that is characteristic in these cultures.
That food is reated to illness is not a new discovery.In 1945,government researchers realized that nitrates,commonly used to preserve color in meats,and other food additives,caused cancer.Yet,these carcinogenic additives remain in our food,and it becomes more difficult all the time to know which things on the packaging labels of processed food are helpful or harmful.The additives which we eat are not all so direct.Farmers often give penicillin to beef and living animals,and because of this,penicillin has been found in the milk of treated cow.Sometimes similar drugs are given to animals not for medical purposes,but for financial reasons.The farmers are simply trying to fatten the animals in order to obtain a higher price on the market.Although the Food and Drug Administration(FDA)has tried repeatedly to control these procedures,the practices continue.
46.Which of the following statements is NOT true?C
A.Some additives are added to the food itself and some are given to the living animals.
B.Researchers have known about the potential dangers of food additives for about sixty-eight years.
C.Drugs are always given to animals for medical reasons.
D.Food may cause forty percent of cancer in the world.
47.How has science done harm to mankind?D
A.Because of science,diseases caused by polluted food have been virtually eliminated.
B.It has caused a lack of information concerning the value of food.
C.The scientists have preserved the color of meats,but not of vegetables.
D.Because of the application of science,some potentially harmful substances have been added to food.
48.What are nitrates used for?A
A.They preserve the color of meats.
B.They preserve flavor in packaged foods.
C.They are the objects of research.
D.They cause the animals to become fatter.
49.The word"carcinogenic"most nearly means"C".
A.trouble-making           B.color-retaining
C.cancer-causing           D.money-making
50.Which might be the best title of the passage?B
A.Drug and Food            B.Food and Health
C.Cancer and Health        D.Health and Drug.

13.It was a cold night in Washington,D.C.,and I was heading back to the hotel when a man approached me.He asked if I would give him some money so he could get something to eat.I'd read the signs:"Don't give money to beggars as most of them are swindlers."So I shook my head and kept walking.
I wasn't prepared for a reply,but with no hesitation,he followed me and said,"I really am homeless and I really am hungry!You can come with me and watch me eat!"But I kept on walking.
The incident kept bothering me for the rest of the week.I had money in my pocket and it wouldn't have killed me to hand over a dollar or two even if he hadn't been a real beggar.On a freezing cold night,no less,I assumed the worst of a fellow human being.
Flying back to Anchorage,I couldn't help thinking of him.I tried to reason my failure to help by supposing government agencies,churches and charities were there to feed him.Besides,you're not supposed to give money to beggars.
Somewhere over Seattle,I started to write my weekly garden column for The Anchorage Daily News.Out of the blue,I came up with an idea.Bean's Cafe,a local charity service kitchen,feeds hundreds of hungry local people every day.Why not try to get all my readers to plant one row of vegetables or flowers in their gardens for Bean's?Plant a row for Bean's.It's clean and simple.
We didn't keep records back then,but the idea began to take off.Folks would fax me or call when they took something in.It's food for the spirit and comfort for my conscience.
In April 1995,the Garden Writers Association of America(GWAA) held their annual meeting in Anchorage and after learning our program,Plant a Row for Bean's became Plant a Row For The Hungry.The idea then was to have every member write or talk about planting a row for the hungry,which brought the program to national attention.
As more and more people participated,new variations cropped up.Many companies gave free seeds to customers and displayed the logo for the program.Donations poured in.It was then that I could really stop feeling guilty.

66.The underlined word"swindlers"in the first paragraph is closest in meaning toC.
A.policemen
B.writers
C.cheaters
D.beggars
67.Why did the author think he assumed the worst of a fellow human being?B
A.Because he didn't show fair respect to a beggar treating him badly.
B.Because he could have helped a hungry man but he passed by.
C.Because he believed that no people begged because of real hunger.
D.Because he thought that charity work was the government's duty.
68.How did the author make up for what he had done?D
A.He set up a local kitchen to help the poor.
B.He planted a row of vegetables for charity.
C.He called on people to donate money to the Bean's.
D.He initiated the idea of Plant a row for Bean's.
69.Which of the following statements is TRUE according to the passage?C
A.The beggar gave up the first time he was turned down by the author.
B.The author invented the program inspired by the Anchorage Daily News.
C.GWAA expanded the program concept and made it nationwide in 1995.
D.The program was later taken over by some seeding companies.

7.An accident in a bicycle race in the United States eight years ago alerted James Chang to the importance of sports medicine.One of his riding companions(25)was injured(injure) severely in the accident.
From then on,Chang,45,a Chinese-American who was born in Anhui province,began to launch business relating to physical safety and medical assistance,particularly in sport.So(26)whenhe took up marathon running two years ago he was shocked to see frequent injuries,many of them avoidable.
"I always heard people talking about people in marathons in China dying suddenly,"he says,adding that one reason why many of these deaths happen is(27)thatthere is a lot of ignorance in China about what marathon running involves.
Many amateur runners in China who are highly competitive get carried away and run at a pace that is far in excess of(28)whatthey can expect their body to take,and even ignore clear signals such as pain,Chang says.
As Chinese have placed more emphasis on leading healthy life-styles in recent years,marathon and other long-distance running(29)have become(become) a highly popular sport across the country quickly.
More than 50 China Athletic Association-sanctioned urban marathons were held in the country last year,and 39 races involving more than 750,000 runners were held the year before.However,long-distance running is a serious business that can exact a heavy physical toll on runners.
"Marathon carries(30)higher(high) risks of injury than other forms of sport,"Hou says,adding that the key to avoiding injury is to strengthen the body through regular exercise and to be aware of one's own physical condition.
Although some chronic injuries are hard(31)to avoid(avoid),even for highly experienced runners,cramp,fainting and shock can easily be prevent(32)ifrunners better understand the sport,he says.

2.Food,football and fashion-Milan has it a11.The city is perhaps most famous for its annual Milan Fashion Week and its world-class soccer teams AC Milan and Inter Milan.And May will see it host the six-month Milan Expo,the theme of which is food and nutrition.
Milan may not the first place tourists think of when they think of Italy.Rome is the most famous city in Italian history,Venice draws visitors who want to travel along its canals and Florence is popular with art lovers.Yet Milan can often be left off tourists'lists.But although some see Milan as the"ugly sister"of these cities,according to Lonely Planet,in 2015the city is"suddenly back in fashion in a big way".
The Milan Expo will look at the future of food,trying to answer the question of how Earth's fast-growing population can be fed in the future.According to Lonely Planet website."144countries will set up shop northwest of central Milan,forming a mini city-within-a-city".
Milan's famous opera house,La Scala,normally closed in the summer,will also host daily performances during the expo,reported Fox News.
Not interested in opera?Don't worry.Visitors who prefer sports may want to visit the San Siro stadium,home of the soccer teams AC Milan and Inter Milan.Tile stadium is one of the most famous in Europe and has seen many important games over the years,both in Serie A and the European Champions League.
So even if all of its fashion and beautiful people can make Milan seem"soulless",as Lonely Planet said.it still has"a serious sense of history and place".Many people will be discovering it this year,and eating great food from all over the world to help solve world problems.Will you?

28.Which of the following statements is True about Milan?D
A.It is the largest city in Italy and has the longest history.
B.It is hosting the world's largest Fashion Week in 2015.
C.Football,fashion and ancient canals are three features of the city.
D.The city's La Scala opera house will offer additional performances in 2015.
