Most people may not think that them am any problems with watermelons, but some Japanese sellers do. Them is often wasted space when they store watermelons, because round watermelons do not sit nicely on shelves. So some clever farmers have solved the watermelon problem. They make their watermelons grow in squaw glass boxes. So the watermelons become square. The only problem now is the price. The square watermelons cost about 80 dollars each.
Many people know the saying, "Roses are red, violets are blue, sugar is sweet and so are you." Well, today the poem needs to change to "Roses are red, roses are blue!" Australian scientists have just recently discovered that when they put a chemical from a blue flower into a rose, they can create nearly 100% blue rose. some of science's inventions are beautiful, not just useful!
Since the mid-1990s,many Chinese farmers have had amazing rice harvests. For many years, Chinese scientists have been working on developing new kinds of stronger rice and now they have produced a new kind, called super rice. Super rice not only can protect itself against insects and diseases, but it also produces more than any other kind of rice. Today farmers can grow almost one and a half times more rice than they could grow in the past.
Doctors might be able to use vegetables to fight cancer now. US scientists have discovered a way to put a chemical into tomato plants while they are growing. When cancer patients eat the tomatoes, the tomatoes will fight the cancer in their bodies. These cancer-fighting vegetables are not yet for sale, because scientists have not finished testing them. If the study finds no problems with the tomatoes, then patients can begin to use this easy and delicious new treatment.

【推荐2】3D printing is becoming more and more popular. We are now able to print things such as clothing, musical instruments and even cars. People and businesses are able to create the things they need very quickly and easily by using 3D printers.
But can you imagine printing food? Some scientists are trying to change the dining experience completely by doing this. They hope that having a 3D printer in the kitchen will become as common as the blender or microwave. Scientists say that they are easy to use: you simply have to choose a recipe(食谱) and put the uncooked food“inks” into the printer to make the food you want. This means that it would be very quick and easy to create tasty and healthy meals.
Using 3D printers to create your meals would also be saving the environment, There would be less need for traditional growing, shipping and packaging steps as food production would be a lot quicker and better. For example, tree leaves and insects could be turned into tasty products!
Printing food could also help people who have a swallowing(香咽) trouble. They could program the printer to print softer kinds of their favorite foods so that they would not have difficulty swallowing them.
However, some people think that a future of 3D-printed food would be a disaster. It could take away many jobs, including those for growing, shipping and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes and structures could be printed from an uncooked “food ink”. Traditional cafes and restaurants might lose business, too.
Also, there are worries about the healthy value of printed food: is it really possible to get what we need from food-based “inks” or something like that?
As we know, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.

【推荐1】World Sleeping Day is on March 21. It wants to tell us sleeping is important for our health. As students, we need to sleep well, because our bodies grow fast when we are sleeping. We can learn better if we have a good sleep. Students about 13 years old need 9 hours of sleep every night. How can we get a good sleep? First, open the window a little to let fresh air in. Our bodies need much air when we are sleeping. Next, when we are in bed, we cannot cover our heads with quilts. If we do, we will not get much fresh air. Then, go to bed and get up at the same time every day. Early to bed, early to rise. What’s more, eating a big dinner or drinking coffee at night is not good for your sleep. Last but not least, don’t put computers or TV in your bedroom. Say no to late-night TV.

Adult(成年的)drivers listen to music on the car radio as they drive to work. They also listen to the news about sports, the weather, and the life of American people. Most of the radio programs are music.
Pop or popular music singers make much money. They make a CD or tape which radio stations use in many places. Once the popular singer is heard all over the country, young people buy his or her tapes. Some of the money from these tapes comes to the singer. Wherever the singer goes, all the young people want to meet him or her. Now the singer has become a national star.
There are other kinds of music that are important to Americans. One is called folk(民间)music. It tells stories about the common life of Americans. Another is called western or country music. This was started by cowboys who would sing at night to the cows they were watching. Today, any music about country life and the love between a country boy and his girl is called western or country music.

Tiny plants and animals live all around us. We cannot see them because they are so small, but they are everywhere. They live in the soil, in the air, and in rivers and oceans. They grow on mountains and in caves. Some live in the ice at the north and south poles; some live where it is very hot. They are found throughout cities and in the country. They grow on other plants and animals. Some are even living on you, on your skin, hair, and inside your body, in your mouth, nose, and all through your body.
These tiny plants and animals are called microbes. The word microbe is made from two other words: micro, meaning small, and bios, meaning life. So, microbe means small life.
Microbes have been on earth for a very long time. They may have been the first forms of life to be alive. Today there are more microbes in the world than all other living things.
People did not know microbes had existed(存在) long. They were too small for them to see.
But people did see many changes in their world—important changes. And they did not know what caused them. They saw food that they kept too long change color and begin to smell bad. They saw cuts and wounds grow red and painful and become worse. They saw old plants and leaves and trees crumble apart on the forest floor and disappear into the soil. Such changes were a natural part of the world, but people did not understand them. They did not know these changes were evidence(证据) of tiny plants and animals growing all around them.
1. Microbes can live everywhere around us.2. Microbes can’t live under icy or hot temperature.
3. Microbes may be older than humans on the earth.
4. People used to know the importance of these tiny living things.
5. The food changes color and smells bad because of the microbes.

Farmer John and his wife lived on a farm. They raised a pig, a cow and a chicken. One day, a mouse saw that John had set a mousetrap(捕鼠器). He went around the farm and warned all of the other animals about the trap.“There is a mousetrap in the house!” the mouse said to the chicken.
“That’s bad news for you, but it doesn’t bother (打扰)me,” the chicken said.
Then, the mouse went to the pig and the cow. But the pig and the cow did not care either. They said they didn’t have to worry about it and wished the mouse good luck.
One night, a snake got caught in the mousetrap. John’s wife thought the snake was dead and tried to remove it. But the snake was still alive and bit her hand. She became very sick and had a bad fever. The farmer decided to make some chicken soup to treat (治疗) her sickness - so he killed the chicken.
As John’s wife continued to become sicker, many of her friends came to visit her. The farmer killed the pig and used it to make food for the visitors. Sadly, John’s wife died from her illness. The farmer killed the cow as a sacrifice (祭品) for her funeral. The mouse watched all of this with great sorrow.

【推荐2】Girls aren't any less capable(有能力的) than boys in the left-brain area. They just do far fewer science and math jobs than boys when they grow up.
Few girls like jobs about science and math, largely because they think they are less proficient (精通)in those subjects than boys. According to a study, only 15 percent of first-year college girls plan to study science, technology, engineering and math. Women make up half of the US workforce, but they only do 20 percent of jobs in science, technology, engineering and math.
The program named The Girls, Math & Science Partnership is for girls aged 11 to 17. “They feel safer taking challenges(挑战), and feel safer asking questions,” Marcia Biswell says. “They seem to have more confidence(自信心) in the things they have learned in that environment.”
Biswell hopes to make excitement about math and science among girls. The girls can grow into women who can someday take a growing number of jobs in math and science.
The program is important to girls because so many high-paying jobs are out there, both now and in the future. In the early school years, girls have as much interest in math and science as boys do. However, the girls lose their interest as they get older.
"Even for kids who don't do math and science jobs, learning these subjects well is helpful for their everyday lives, such as spending money," Biswell says. "We can't turn them all into a scientist or an engineer or a doctor, but we can at least show them how math and science can be used in their lives."

The kind of morning that was inviting me with a warm arm.
So I decided to spend an hour doing almost nothing,
Sitting and enjoying the best of what nature could bring.
Getting up from my chair, I thought I'd take a walk,
Then there was a bee that suddenly came to me for a talk.
There was a kind of music as the bee moved its wing,
Music so perfect that no one could ever sing.
Walking little further, I saw a butterfly,
Which was dancing among the flowers and then flying high.
My morning hour in the garden was very well spent,
And now I know what beauty and music really meant!!
