There’s no pizza on Mars, but scientists have found a solution to this problem for hungry astronauts: a pizza printer! NASA, the American space agency, has developed a machine that “prints” food. They showed a model of the printer in Austin, Texas last month.
How does it work? Cartridges(墨盒) filled with powdered dough(面粉团), cheese, sauce, water and oil put the ingredients layer(层)by layer onto a printer bed. The printer bed, which gets hot from below, cooks the food as it’s being printed.
Since most of the ingredients are powdered, they can be sent into space and stored for many years without going bad. Water makes food go sour, so the food powders are mixed with water and oil only when they are being printed.
“Long-distance space travel requires more than 15 years of shelf life for food.” says Anjan Contractor, whose company developing the printer. “ We take water out, and in that form, food will last maybe 30 years.”
In outer space, there are far fewer choices for astronauts for dinner. Most of their foods—even things like beef or shrimp—are eaten from bags as powders（粉末）. Scientists hope the new food printer can be used to make more delicious food in outer space, keeping astronauts healthier and happier.
But the printer is not limited to use in outer space. Scientists think it could be useful on Earth, too. It could allow personal meals to be made at the dinner table, according to each person’s different needs.
“Let’s say someone is an athlete in the family, and he needs more protein(蛋白质),” says Anjan Contractor, founder of Systems and Materials Research Corp, the company developing the printer. “We can design recipes for him and print out more protein-nutritious food for him.”

“Children need more geography field trips. Schools should organize geography field trips to stop pupils from sitting before computer screens for a long time. And children should be encouraged to see the natural world and study geography,” says Michael Palin.
The famous actor and writer, Michael Palin, made the comments days after a study showed that pupils in the UK were less likely to take part in science field trips than in most other developed countries.
The study found that 13% of schools in the UK failed to take children out of the classroom regularly.
Mr. Palin said that field trips were an important part of geography and that he was interested in geography because he had a good geography teacher and he had many opportunities to “get out of the school building”.
In an interview, Mr. Palin said, “It was important for children to see things for themselves and learn about the rest of the world. You have to show them a mountain, show them a factory, show them a power station.”
Mr. Palin had been to the North and South Poles, the Himalayas（喜马拉雅山脉）, the Sahara and Eastern Europe.
“Geography is about the study of the earth. It is a wide-ranging subject,” he said. “It’s related to everything we do: what we eat, what transport we take to work, where we live, what houses are made of, and so on.”
He said children needed to get basic geography knowledge first and that once they had the basic knowledge they could move on to deeper problems, such as population and pollution. “Today’s children will need to deal with a lot of problems when they grow up. They have to learn geography today,” he said.

Liang Huili is the leader of Huana International Volunteer Service Group，with hundreds of students, young professionals and business leaders. They held a basketball match to help 150 poor students in western China with school supplies(用品) and winter clothes. She also worked with an organization in the US to raise money for children with heart disease.
Born in Guangdong Province in 1942, Liang moved with her family to Taiwan at the age of seven. Liang taught at a primary school for seven years until her boyfriend went to America in 1969, one year after they got married.
“We didn’t have much money,” she says, “ so I started babysitting for other Chinese families and taking care of my own daughter at the same time.” She also taught children Chinese at Chinese schools. What’s more, she would help newly arrived Chinese families find apartments and work, and sometimes lend them money.
“I remember those students from China who first came in 1986. They didn’t have much money, and idea of what to do,” Liang told us. “ I then asked people in my neighborhood and my Chinese friends for donations(捐赠)－not only some money but also small electronic appliances needed for daily living.”
One of her experiences in Dayton, Ohio made her want to make volunteering a vocation(职业). She remembers how she once collected(接走) two Chinese professors who had missed their flight and had no one there to pick them up. A friend told Liang about it, and she went to meet them herself around midnight. She found the men feeling lost in that strange country, where no one spoke their language. They didn’t want to go to an American hotel, and didn’t know how they would get to Columbus the next day. “ So I talk to them and took them home with me,” she says, “ and today, I am still in touch with those two professors. We are good friends.”
