How do you deal with plastic bags from the supermarket ？Throw them away or recycle them？ How about eating them？
The bags are no harmful to the environment． Humans and animals can safely eat them．Indian company EnviGreen has made a bag with natural materials．It looks and feels just like plastic ，but can be broken down（分解） easily．
Ashwath Hedge who set up the EnviGreen company spent four years doing experiments（实验） with 12natural materials． They include potato ，corn，vegetable oil and banana．He made the materials into liquid and used the liquid to make the bag．
Although the EnviGreen bag is more expensive than a common plastic bag， it has many advantages．According to the Wall street Journal， it takes 1000years for common plastic bags to break down．But an EnviGreen bag can naturally break down in less than 180days．It also breaks down in less than a day in water．Hedge was happy to show it in his interview， he put an Envi Green bag in water and ate it with a smile．
There are more than 15000tons of plastic waste in India every day． But only 9，000tons are processed．In China，3billion plastic bags are used every day．Maybe EnviGreen bag could be a solution（解决办法）to the world problem of plastic plastic pollution．

Once upon a time, a man punished his 5-year-old daughter for using up the family' s expensive gold wrapping (包装 ) paper. Money was always not enough, and he became even more upset when on Christmas Eve, he saw that the child had pasted ( 贴) the gold paper to decorate a shoebox to put under the Christmas tree.
The next morning the little girl, filled with excitement, brought the gift box to her father and said, "This is for you, Daddy!"
As he opened the box, the father was sorry for his earlier behavior.
But after he opened it, he found it was empty and again he was angry."Don' t you know, young lady, " he said, "when you give someone a present there's supposed to be something inside the package!"
The little girl looked up at him with tears running from her eyes and said, "Daddy, it's not empty. I blew kisses into it until it was all full."
When the father heard this, he fell on his knees and put his arm around his dear little girl. He begged her to forgive him for his unnecessary anger.
An accident took the life of the child only a short time later. It is told that the father kept that little gold box by his bed for all the year of his life. Whenever he was sad or faced difficult problems he would open the box, take out an imaginary kiss, and remember the love of this beautiful child who had put it there.

New Energy in the Twenty-first Century Energy from the wind.
All over the world, people use the power of the wind. It is a clean source of energy, and there is lots of it. But if the wind does not blow, there is no wind energy.
Energy from the water
When water moves from a high place to a lower place it has the power to make electricity. In Britain, waterpower produces enough energy to power a town with 40000 people. Waterpower gives energy without pollution, but people have to build dams(大坝) to use this kind of power, and building dams is very expensive.
Energy from the earth
There is heat in the rocks under the earth. Scientists use the heat to make geothermal(地热的) San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is only possible in a few places in the world.
Energy from the sun
Solar panels(镶板) on the roofs of houses and buildings can turn energy from the sun into electricity. These panels can create enough energy to heat the whole house during winter. Solar power is clean and plentiful, but when the weather is bad, it can’t produce power.

We have always been interested in the moon.2000 years ago, people already knew that the moon moves around the earth and where it would be in the sky at different times of the year. At that time, everything about the moon was learned by watching it carefully in the sky.
When scientists could use telescopes to study the moon more closely, their ideas began to change. They could see the moon was made of rocks. Most scientists thought moon rocks would be different from those on the earth. This was because they believed the moon had once been a planet that had been caught in the earth’s gravity millions of years earlier.
In 1969, moon rocks werefinally brought to the earth and studied. Much to their surprise, scientists found that, except for water, the moon and the earth were made of the same things. Once again new ideas were needed for this new information.
After years of study, most scientists now think that the moon was once part of the earth. They believe very early in its history, maybe 4 billion years ago, something about the size of Mars hit the earth. This sent billions of rocks into space around our planet. These rocks slowly joined together and after many years became the moon.
In the future, even thought our ideas about the moon may change again, we will still be interested in it.2000 years ago, people already knew_____.

| A．the earth was once part of the moon |
| B．the moon was once part of the earth |
| C．something about the size of Mars will hit earth in the near future |
| D．a lot of rocks will slowly join together to become the other moon |

When Susan White went back to high school a couple of years ago, she never had any thought about actually getting a high school diploma.
“I just wanted to learn more,” she said. But when she found out that many of her classmates were planning to graduate, Mrs. White recalled(回顾), “I said my young friends can graduate from high school, so can I.”
She seems to have been right. As soon as she finishes a history course, Mrs. White will graduate next month. And when she does, she will enter the record books as the oldest person ever to graduate from high school in the United States.
Mrs. White is 98 years old and nobody has finished high school at an older age.
Mrs. White dropped out of school(退学) in the 10th grade, but her ability to learn has clearly not been reduced after she left school for 80 years. Since going back to her studies, she has kept up a straight record that is the highest possible.
Now that she is about to get a diploma, Mrs. White has become a strong believer in getting a good education.
“I don’t like anyone dropping out of school,” she said. “It makes me mad when a person decides to leave school, because future generations(后代) will have to know even more than we do in order to survive(生存)”.Mrs. White sets a good example of lifelong study!Mrs. White dropped out of school when she was about_____.
