Many Americans concerned about pollution are demanding cleaner supplies of energy. The demand has resulted in increased research about ethanol fuel. Ethanol is an alcohol that can be mixed with gas. It burns up most of the pollutants in gas. It replaces some of the chemicals that are known to cause cancer, and it can be produced in the United States.
Some experts say that in the future ethanol will replace some of the oil imported into America. Today ethanol is less than one percent of total American fuel supply. The head of the National Corn Growers Association, Kieve Hard, says ethanol will provide twenty-five percent of the fuel supply by 2030. The organization is involved in the production of ethanol because it can be made from corn.
One company in the American Midwest says it is starting to produce ethanol because of demands from people and from the government. The Congress approved the Clean Air Act in 1990. The company says this means the market for ethanol will expand. The company is a major producer of corn starch that can be used to make ethanol.
At Texas A and M University Professor Mark Holzapple produces ethanol from materials found in solid waste. He has developed a way to turn materials like paper into simple sugar. He then uses yeast to turn the sugar into ethanol. Professor Holzapple says two hundred liters of ethanol fuel can be produced from one ton of solid waste.
A professor at the University of Arkansas, John Geddie, is exploring another way to make ethanol. He is using acids on paper material. He says a large factory could produce ethanol from waste paper at a cost about the same as the cost of producing gasoline.
Environmentalists support the use of ethanol because it turns solid waste into a useful product. Professor Holzapple says law makers in industrial nations need to support the development of this clean, less expensive fuel of the future.Why does the interest in ethanol fuel increase in the United States according to the passage?

Americans love to talk and generally it is OK to talk even to strangers about nearly any subject at any time as long as you are polite．However there are some subjects，like racism，American foreign policy，gun ownership，and religion that are best discussed among friends．
In America，it is OK to approach a stranger and start up a conversation with him as long as the subject is not too abstract．In America，it is not considered inappropriate to talk to people you don’t know．Talking to a stranger about the weather or the quality of nearby restaurants，or the prices in a grocery store is all perfectly fine．Even complimenting someone on the car they drive or asking them where they bought their clothes are all appropriate topics of conversation with complete strangers．
Generally，Americans prefer that people say what they think and they respect frankness．Usually when it comes to personal matters，it’s best to accentuate(强调)the positive：don’t tell someone that their children are ugly or that their cooking is terrible．However；it’s OK to tell someone that they are wrong as long as you do so politely and with respect．Americans generally believe that you show someone respect by telling them the truth．Don’t be afraid to be honest with Americans，but be appropriate．

Science can’t explain the power of pets，but many studies have shown that the company of pets can help lower blood pressure(血压) and raise chances of recovering from a heart attack，reduce loneliness and spread all-round good cheer．
Any owner will tell you how much joy a pet brings．For some．an animal provides more comfort than a husband／wife．A 2002 study by Karen Allen of the State University of New York measured stress(紧张)1evels and blood pressure in people－half of them pet owners－while they performed 5 minutes of mental arithmetic(算术)or held a hand in ice water．Subjects completed the tasks alone，with a husband／wife，a close friend or with a pet．People with pets did it best．Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates．With pets in the room，people also made fewer math mistakes than when doing in front of other companions．It seems people feel more relaxed(放松)around pets，says Allen，who thinks it may be because pets don’t judge．
A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits．Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs；a separate group of 56 people without pets were put on a diet program．On average，people lost about 11 pounds，or 5％ of their body weight．Their dogs did even better，losing an average of 12 pounds，more than 15％of their body weight．Dog owners didn’t lose any more weight than those without dogs but，say researchers，got more exercise overall－mostly with their dogs--and found it worth doing．What does the text mainly discuss?

How Can Excess Weight Hurt Your Health?
It's hard to feel good when your body has too much weight to carry. Being overweight or obese can make it harder to breathe and sleep. It can make a person feel tired and cause aches or pains. A weight problem also can make you embarrassed, sad, or even angry.
___________________________?
One of the best ways to stay at a healthy weight is to be active. You can join a sports team. Or, if you don't like team sports, try swimming, tennis, martial arts, or just being active in your own backyard. Jumping rope, dancing, and running around will get your heart pumping.
Getting some extra exercise can be as easy as taking the stairs instead of the elevator or walking instead of having your parents drive you. Being active also means watching less TV and playing fewer video games.
___________ is another part of staying fit. Aim to eat a variety of foods and get five servings of fruits and vegetables a day. Choose water and low-fat milk over soda and other sugary drinks. When it comes to high-calorie and high-fat foods, eat them only once in a while and, when you do, have smaller portions.
What Should You Do?
Talking to a parent is the best first step if you are concerned about your weight. Your mom or dad can make a doctor's appointment for you. The doctor may suggest ways of changing your eating and exercise habits.
In general, kids don't need to diet. But a kid who is very overweight may need some expert help from a dietitian or a doctor who specializes in weight management. Together, along with your family, you'll be able to come up with a safe and healthy plan that should include eating nutritious foods and exercising regularly.What is the best title of the second part?

A blocked airway(呼吸道) can kill someone in three to four minutes, but it can take more than eight minutes for an ambulance to arrive. So a simple procedure such as opening someone's airway can save their life while they're waiting for emergency medical help. This means you're more likely to give first aid to someone you know than a stranger.
There are many misconceptions(误解) surrounding first aid. Below are the ‘most popular’ ones with details of what you should do.
You should put butter or cream on a burn. The only thing you should put on a burn is cold water - keep the butter for cooking. Put the affected area under cold running water for at least ten minutes.
The best way to treat bleeding is to put the wound under a tap. If you put a bleeding wound under a tap you wash away the body's clotting agents(凝血剂) and make it bleed more. Instead put pressure on the wound with whatever is available to stop or slow down the flow of blood. As soon as possible call 999. Keep pressure on the wound until help arrives.
Nosebleeds are best treated by putting the head back. If you put the head back during a nosebleed, all the blood goes down the back of the airway. Instead advise them to tilt(倾斜) their head forwards and ask the person to pinch(捏) the end of their nose and breathe through their mouth.
You need lots of training to do first aid. You don’t - what you mostly need is common sense. You can learn enough first aid in a few minutes to save someone's life – whether it’s from a book, attending a course or watching videos online.
