One-off chopsticks are very popular, but now using them has some problems.
Some people think we shouldn¡¯t use them any more. On one hand, we need to use a lot of wood to make them. On the other hand, they pollute environment after we use them. What¡¯s worse, many one-off chopsticks are not clean enough for people to use. They are bad for our health.
But others think we should keep using them. Because it is very convenient to use them. Then, it is much cleaner and healthier to use them than the traditional chopsticks. And it is helpful to save some water because we don¡¯t need to wash them after using.
In my opinion, I think we should use fewer one-off chopsticks so that we can save more trees. And we should also use clean chopsticks to keep healthy.

¡¾ÌâÄ¿¡¿ More than its influence on health, not getting enough sleep can lead to car accidents or other mistakes. Here are what sleep researchers have found about how to sleep.
How much sleep do we actually need?
It is known that all of us naturally need no less than 8 hours of sleep per night. When we sleep below six hours per 24, we¡¯re at an increased risk of health problems. Some of us think we can make up any of those hours lost during the week on the weekends. Suddenly there is no storage system for sleep in the brain.
Can we train ourselves to need less sleep?
As a study in 1964, a 17- year- old boy named Randy Gardener stayed awake for 264 hours. How many people could do anything close to that without dying?
When you are reading this, you might say you usually get 6 hours of sleep and feel just fine . Sleep experts often compare people without enough sleep to drunk drivers: They don't get behind the wheel thinking .They are probably going to kill someone.
Can we drink coffee instead of sleeping?
Coffee can keep us awake. Remember, too much coffee may throw off our sleep and energy cycles. So avoid caffeine for 4 to 6 hours before bedtime.
Does a sense of purpose connect with sleep quality?
A new research suggests a kind of strong connection between purpose in life and sleep. People who have a great sense of purpose usually have better physical and mental health, which in turn explains their higher quality sleep. Perhaps developing a sense of purpose in life could be as useful at improving sleep as the healthy habits above.

¡¾ÌâÄ¿¡¿ When our son Peter was twelve, the new bicycle he had received was stolen. Owning a bicycle was big fun to our children when they were little. They spent hours and hours, day after day, on their bicycles, riding up and together as a family a lot. Bicycling was a great way to get the kids out of the house and into the fresh air without spending the money.
When Peter and his sister went outside for a morning ride, he discovered that his bicycle had been stolen from our backyard. He couldn't believe that someone would do this.
He got a large piece of cardboard, painted a sign begging for the bicycle to be returned, and tied the sign to the letterbox. The following morning, when I went out to collect the mail, I found a white envelope with the magical words, "Buy yourself a new bicycle". There was a $ 100 banknote inside.
We were very touched that someone had the heart to do this. We'd never been able to thank the person but we guessed that it may have been one of our wonderful neighbors. Peter painted a big "Thank you!" on the sign and we left it outside for a couple of weeks afterwards, hoping the kind stranger would drive down our street and see it.
Peter was able to own a new bicycle again. As the years went on, the bicycle became older but remained just as important as before. Now Peter is 25.
All these years later we are still thankful for the stranger's kindness. We were a young family with three little children and it meant a lot to us. We still talk about it and, even now, wonder who the kind stranger was.

¡¾ÌâÄ¿¡¿ Since the first Earth Day in 1970, Americans have gotten a lot ¡°greener¡± toward the environment. ¡°We didn¡¯t know at that time that there even was an environment, especially we didn¡¯t know that there was a problem with it,¡± says Bruce Anderson, president of Earth Day USA.
But what began as nothing important in public affairs (¹«¹²Ê¼þ) has grown into a social movement. Business people, political leaders, university professors, and especially millions of grass-roots (²Ý¸ù) Americans are taking part in the movement. ¡°The understanding has increased many, many times,¡± says Gaylord Nelson, the former governor from Wisconsin, who thought up the first Earth Day.
According to US government reports, emissions from cars and trucks have dropped from 10.3 million tons a year to 5.5 million tons. The number of cities producing CO beyond the standard has been reduced (¼õÉÙ) from 40 to 9. Although serious problems still remain and need to be dealt with, the world is a safer and healthier place. A kind of ¡°green thinking¡± has become part of practices.
Great improvement has been achieved. In 1988 there were only 600 recycling programs; today in 1995 there are about 6,600. Advanced lights, motors, and building designs have helped save a lot of energy and therefore prevented pollution.
Twenty-five years ago, there were hardly any education programs for environment. Today, it¡¯s hard to find a public school, university, or law school that does not have such a kind of program. ¡°Until we do that, nothing else will change!¡± says Bruce Anderson.
¡¾1¡¿According to Anderson, before 1970. Americans had little idea about ________.
A.the social movementB.recycling techniques
C.environmental problemsD.the importance of Earth Day
¡¾2¡¿Where does the support for environmental protection mainly come from?
A.The business men.B.Common people.

¡¾3¡¿What have Americans achieved in environmental protection?
A.They have cut car emissions to the lowest.
B.They have solved their environmental problems.
C.They have lowered their CO levels in forty cities.
D.They have reduced pollution by taking active actions.
¡¾4¡¿What does the underlined word ¡°emissions¡± mean in the passage?
A.ÈÈÁ¿B.βÆøC.ȼÓÍD.ÎÛȾ
¡¾5¡¿What is especially important for environmental protection according to the last paragraph?
A.Education.B.Planning.C.Green living.D.Green thinking.
