There’s a new frontier (新领域) in 3D printing that’s beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn’t stopping there.
Food production
With a 3D printer, a cook can print complicated (复杂的) chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that—it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.
Nutrition
Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow consumers to print food to meet their own nutritional needs, like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand.”
Challenges
Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste (糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.
1.What benefit does 3D printing bring to food production?
A. It helps cooks to create new dishes.
B. It makes the dishes more delicious.
C. It saves time and effort in cooking.
D. It contributes to restaurant decorations.
2.According to Paragraph 3, 3D-printed food____________.
A. is more available to customers.
B. can keep all the nutrition in raw materials.
C. is more tasty than food in supermarkets.
D. can meet individual nutritional needs.
3.What could be the best title of the passage?
A. 3D Food Printing: From Farm to Table
B. 3D Food Printing: Delicious New Technology
C. The Challenges for 3D Food Production
D. A New Way to Improve 3D Food Printing

There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.
Food production
With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that---it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to" re-create forms and pieces" of food that are" exactly the same,” freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.
Sustainability(可持续性)
The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids( 水解胶体)from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原 料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.
Nutrition
Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday 's bread from the supermarket, you' d eat something baked just for you on demand."

The 3D-printing industry is accelerating its efforts to help fight the new coronavirus and the disease it causes, COVID-19.
On Tuesday, HP announced it’s working with those who bought its 3D printers to make medical face shields, hands-free door openers and an adjuster for face masks for medical staff who often must wear them for hours. It’s also testing “hospital-grade” face masks meeting the higher-end FFP3 (过滤式面罩) standard and parts for simple emergency ventilators (呼吸机) and it’s looking into nasal swabs to test for COVID-19 infection. HP also is offering free downloads of its 3D-printed medical equipment designs.
Carbon, whose 3D printers are used to make everything from bicycle seats to teeth straighteners, said it plans to send face shield designs to its network of customers who’ve bought its 3D printers. Carbon co-founder and Executive Chairman Joseph DeSimone said on Monday the company expects to send the designs by early Tuesday.
3D-printcr makers typically sell their products to others that actually do the 3D printing. One such customer, Ford, said Tuesday that it’s made 1,000 face shields and shipped them to Michigan hospitals, with plans to make 100,000 face shields a week. It is also working with 3M and General Electric on respirator masks and ventilator designs.
The effort is one of several to apply 3D-printing technology to the fight against coronavirus. 3D printing isn’t as fast at churning out products as conventional mass production methods. But 3D printers are flexible and able to make many different parts anywhere there’s a printer and raw materials like the plastic resins Carbon printers use.
Some 3D-printing efforts have focused on ventilators, which expected to be in short supply with a surge of COVID-19 patients suffering from respiratory (呼吸器官) problems. Also in short supply arc N95 masks that can be useful in reducing the likelihood a wearer will spread COVID-19 to others.
Carbon’s DeSimone is cautious about the enthusiasm, though, saying that regulatory approval is important and that 3D-printcr enthusiasts shouldn’t be making components not intended for close human contact that might release unhealthy gases.
1.What is the passage mainly about?
A.An introduction about 3D-printing.
B.The 3D-printing industry’s efforts to help fight COVID-19.
C.The products that 3D-printing makers sell.
D.How 3D-printing makers produce medical equipment.
2.HP announced to help its customers to make the following products except for_____________.
A.medical face shields B.hands-free door openers
C.an adjuster for face masks D.emergency ventilators
3.Which of the following is true according to the passage?
A.Carbon’s company will finish its design after Tuesday.
B.Ford has made 1,000 face shields end plans to make 10,000 more in a week.
C.3D printers arc more flexible than traditional mass production methods.
D.Most 3D-printings focus on making ventilators and N95 because of their short supply.
4.What can be inferred from the last paragraph?
A.3D-printing may release unhealthy gases.
B.DeSimone is cautious about 3D-printing.
C.Carbon’s company didn’t gain regulatory approval of making medical equipment.
D.3D printers aren’t enthusiastic about making components designed for close human contact.

That year, in the local school, there was a new math teacher, as well as some new pupils. One of the new kids was the stupidest child that anyone had ever seen. It made no difference how quickly or how slowly they tried explaining numbers to him; he would always end up saying something enormously stupid. Like two plus two was five, seven times three was twenty-seven, or a triangle had thirty corners...
Before this boy arrived, math lessons had been the most boring of all. Now they were great fun. Encouraged by the new teacher, the children would listen to the pieces of nonsense spouted by the new kid, and they would have to correct his mistakes.
Whenever the new teacher asked questions, the stupid kid would stand up but made the wrong answers, the other students all wanted to be the first to find his mistakes, and then think up the most original ways to explain them. To do this they used all kinds of stuff: sweets, playing cards, oranges, paper planes, etc. It didn't seem like any of this bothered the new kid.
However，little Lewis was sure that it was bound to make him feel sad inside. Lewis was sure he would see him crying. So，one day, he decided to follow the new kid home after school. On leaving school, the new kid walked a few minutes to a local park, and there he waited for a while, until someone came along to meet him...
It was the new teacher!
The teacher gave the new kid a hug, and off they went, hand in hand. Following from a distance, Lewis could hear they were talking about math.

What are the biggest problems that society will have to deal with in the new age? There are diseases like AIDS and cancer. There’s climate change, of course. And what about producing enough cheap food and energy for the world’s growing population? Who’s going to solve all these terrible problems? Yes, politicians and world leaders will have a big part to play. Yes, businesses will need to create the economic wealth to pay for some of these things. But who’s going to make a much greater difference to something like AIDS or climate change? It’s going to be a scientist. It is the scientist who can turn some new bit of science into a new technology to solve these problems.
If you like thinking about the world around you, why not become a scientist? It doesn’t mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine! Scientists do all kinds of amazing things that are actually interesting!
Military scientists develop not only new weapons but new military technologies that could help make wars out of date. Forensic(法医的) scientists work with the police to find quite small clues to catch criminals. Scientists work in schools and colleges as the teachers and professors who will train tomorrow’s scientists. Don’t think a scientist is far away! Maybe you like cooking? You could be a food technologist helping to keep fruit and vegetables fresher for longer. Perhaps sport is your thing? Do you know that most top athletes work with sports scientists in order to improve their performance? You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world.
Looking for something to do for the rest of your life? My advice? Take a long and hard look at science. It is interesting and ever.
