12．The way we cook is important．In many countries，the two sources of heat used for cooking are nat-ural gas or electric stoves．The World Health Organization （WHO） warns that millions of people are dying every year from indoor air pollution．The WHO finds that poor cooking，heating and lighting technologies are killing millions of people each year．
     Indoor air pollution results from the use of dangerous fuels and cook stoves in the home．WHO of-ficials say nearly three billion people are unable to use clean fuels and technologies for cooking，heat-ing and lighting．And they say more than seven million people die from exposure to indoor or outdoor air pollution each year．Of that number，the WHO says about 4.3 million people die from household air pollution given off by simple biomass（生物燃料 ） and coal stoves．
       These findings show that the home use of poisonous fuels is to blame for many of these deaths．
 These fuels inrlude wood，coal，animal waste and so on．Carlos Dora is Coordinator in the WHO's De-partment of Public Health，Environmental and Social Determinants of Health．He says people should  not use unprocessed coal and kerosene （煤油 ） fuel indoors．He says opening a window or door to let out the harmful air will not correct the situation．It will only pollute the outdoors．"New technologies  and clean fuels can rid people of this problem．"
         The United Nations found that more than 95 percent of families in suh-Saharan Africa depend on  solid fuels for cooking．It says huge populations in India，China and Latin American countries，such as Cuatemala and Peru，are also at risk．
         Nigel Bruce is a professor of Public Health at the University of Liverpool．He says researchers are developing good stoves and other equipment to bum fuels in a more efficient way．"There are already many technologies for clean fuels available now．An effective and reasonably low-cost ethanol（酒精）stove that is made by Dometic （a Sweden-based company） is now being tested out．Another interesting development is electric induction stoves．"In India，you can buy an induction （屯磁） stove for about 8．AndinAfricayoucanbuyasolarlampforlessthan1．

A．People should use an effective air cleaner．
B．People should use new technologies and clean fuels．
C．People should open a window or door to let out the harmful air．
D．People should prevent themselves from being exposed to harmful air．

2．When Russell Lyons volunteered for the first time，he read Goodnight Moon to a class of San Diego preschoolers．And it wasn't reading-he'd memorized the book and was reciting it out loud．He was 4．Still，he said it felt good up there，in front of the other kids，lending a hand．He wanted more of that feeling．
Thirteen years later，he's getting a lot of it．He's on a five-month road trip across America-not sightseeing，but volunteering．
The University City resident has spent time at an animal reserve in Utah，a women's shelter in St．Louis，a soup kitchen in New York，a retirement home in Tucson．This week he's in Los Angeles，at a program that supports disabled youth．
"I just like helping people and feeling that something I do is making a difference，"he said．He resists the idea that his"Do Good Adventure"is all that unusual．It bothers him that the media often describes young people as lazy，self-centered and materialistic．So he sees his trip as a chance to make a statement，too．"About 55percent of teens do volunteer work，higher than the rate of adults，"he said，according to a 2002study．"Not everybody knows that．"
Of course，some teens do volunteer work because it looks impressive on their college applications．Lyons said he mentioned his trip on his submissions．But charity work is a habit with him．Even before the cross country trip，he was volunteering abut 200hours a year at various places．He's made sandwiches for homeless families in Washington D．C..He's taught math to fifth-graders in Cuernavaca，Mexico．
He gets some of that drive from his mother，Leslye Lyons，who has been involved in nonprofits for much of her life．She was there when her son"read"to the preschoolers-a memory of hers"that will never go away．"

56．What did Russell Lyons think of his first volunteering？C
A．Creative．    B．Persuasive．
C．Impressive．  D．Imaginative．
57．The third paragraph is meant toA．
A．indicate Russell Lyons is working as a volunteer
B．introduce some tourist attractions across America
C．a(chǎn)ppeal to volunteers to offer help to those in need
D．show volunteers are needed in all parts of America
58．According to Paragraph 4，Russell Lyons is against the idea thatC．
A．what he has done is common
B．most teens do volunteer work
C．young people don't work hard
D．a(chǎn)dults prefer to be volunteers

A．it is necessary for college applications
B．it has become a natural part of his life
C．he likes the feeling of being praised
D．he ought to keep his promise to Mom．

4．Like international travelers anywhere，foreigners visiting the United States from other countries can be confused by some of what they encounter．Fortunately，their fellow travelers have plenty of advice．Here are some specially good travel advice from around the world．
From Italy：
Tipping is filled with misunderstanding．Q．Is it true that I have to"force"to tip at all？A．It is not mandatory to tip，however，it is strongly recommended，because in many cases it is the only entry of workers．Generally in a restaurant，in the cab，and in many places where there is a service tip is 15%．Since the bill that will explain you exactly the city tax of 8.875%，is sufficient to double that sum，without bothering to do the calculations．In the hotel you leave two dollars per day per person cleaning．Obviously you do not leave tips in places like McDonalds or Starbucks．
From China：
Americans love to follow rules，even when no one is looking．"Americans are such strict rule followers．I witnessed this once sitting on the sidelines of a high school dodge ball game．To me，it was ridiculous，a little violent，and very American．It struck me that my classmates followed the rules of the game so strictly．Even when no one noticed that a person had been hit and he could have kept playing，he voluntarily gave himself up and left the game．I was deeply impressed by how much people honored the rules even when they are not seen．"
From Russia：
Gifts are not a big deal．And did you know bribery （行賄） was illegal？"Gifts：Americans do not expect them．On the contrary，an unexpected gift while conducting business can put an American in an awkward position．Such things for Americans suggest exchange of commercial．
Business gifts in the U．S．a(chǎn)re not acceptable．Moreover，they often cause suspicion．Americans fear that they could be interpreted as a bribe，and in the United States that is strictly punishable by law．"
From Japan：
Nobody is impressed by how much you can drink．"In the U．S．，they do not have a sense of pride if they drink a large amount．Rather，if you drink a lot，there is a sense that you cannot manage yourself，and you can lose respect from those around you．Being drunk doesn't excuse your actions，and to drink alcohol habitually is a sign of alcoholism．Alcoholics are seen as mentally weak，and are avoided by society due to their inability to have self control．"

46．What does the passage mainly tell about？B
A．Cultural diversity．
B．Cultural differences．
C．Cultural revolution．
D．Cultural construction．
47．Which is closest in meaning to the underlined word"mandatory"in Para.3？A
A．Required．
B．Forbidden．
C．Permitted．
D．Arranged．
48．According to the passage，what are Americans most likely to do？D
A．Tipping everywhere．
B．Sending a surprising business present．
C．Drinking a lot．
D．Obeying the game rules．
49．Which word do the international travelers probably use to describe Americans？B
A．Confident．
B．Self-disciplined．
C．Selfless．
D．Generous．

2．Emotional eating is when people use food as a way to deal with feelings（81）instead of satisfying hunger．Believe it or not，we've all been there．Have you ever finished a whole bag of chips out of boredom or downed cookie after cookie while preparing（82）for a big test？But when done a lot-especially （83）without/before realizing it-emotional eating can affect weight，health，and overall well-being．
Understanding what drives emotional eating can help people（84）take steps to change it．One of the biggest myths about emotional eating is that it's caused by （85）negative feelings．Yes，people often turn to food when they're stressed out，lonely，sad，anxious，or bored．But emotional eating can be linked to positive feelings too，like the romance of sharing dessert on Valentine's Day or the celebration of a holiday feast．Sometimes emotional eating is tied （86）to major life events，like a death or a divorce．More often，though，it's the countless little daily stresses （87）thatcause someone（88）to seek（seek） comfort in food．
We're all emotional eaters to a degree．But for some people emotional eating can be a real problem，（89）causing （cause） serious weight gain or other problems．The trouble with emotional eating is that once the pleasure of eating is gone，the feelings that cause it remain．And you often may feel worse about eating the amount or type of food you like．That's（90）why it helps to know the difference between physical hunger and emotional hunger．
Next time you reach for a snack，wait and think about which type of hunger is driving it．
