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."
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 doubtful about 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?

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

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.

During the early years of American settlement, a new form of English was beginning to develop in the islands of the West Indies and the southern part of the mainland, spoken by the black population. The beginning of the seventeenth century saw the happening of the slave trade. Ships from Europe travelled to the West African coast, where they exchanged cheap goods for black slaves. The slaves were shipped in terrible conditions to the Caribbean islands and the American coast, where they were in turn exchanged for such products as sugar and molasses(糖蜜). The ships then returned to England, completing an “Atlantic triangle”of journeys, and the process began again. Britain and the United States had outlawed the slave trade by 1865, but by that time, nearly 200 years of trading had taken place. By the middle of the nineteenth century, there were over four million black slaves in America.
The policy of the slave-traders was to bring people of different language backgrounds together in the ships, to make it difficult for groups to plan rebellion. The result was the growth of several pidgin (混杂语言) forms of communication, and in particular a pidgin between the slaves and the sailors many of whom spoken English. Once arriving in the Caribbean, this pidgin English continued to act as a major means of communication between teh black population and the new landowners, and among the blacks themselves. Then, when children came to be born, the pidgin became their mother tongue, thus producing the first black Creole(克里奥尔语) speech in the region. This Creole English rapidly came to be used throughout the cotton plantations (种植园), and in the coastal towns and islands.
1.Which of the following shows the route of slave trade correctly?
A.EuropeWest African coastthe Caribbean islands and the American coastEurope
B.EuropeWest African coastEuropethe Caribbean islands and the American coast
C.West African coastEuropethe Caribbean islands and the American coastEurope
D.West African coastEuropethe Caribbean islands and the American coastWest African coast
2.It can be inferred that the slaves in the same ship ____.
A.didn’t communicate with each other
B.could understand several languages
C.spoke different languages
D.came from the same place
3.Creole speech comes from _____.
A.Spanish and English
B.English and an African language
C.a European language and an American language
D.an African language and an American language
4.What is the text mainly about?
A.The history of slave trade. B.“Atlantic triangle” of journeys.
C.Languages spoken in America D.The birth of black English

If you expect to work in the future in the travel industry, you should begin learning Chinese.
That’s because Chinese people spent nearly$258 billion in total on international travel last year. That’s more than twice the combined amount spent on international travel by people from the United States and Germany, the next two biggest-spending nations. The Chinese are relative(相对的)newcomers when it comes to traveling beyond their nation’s borders and only a small percentage of them travel outside of China each year. Given the size of that nation’s population. even that small percentage represents well over 100 million Chinese travelers to foreign destinations.
Yet Chinese citizens flew, on average, just 65 miles last year versus(与……相对)the 227 miles flown on average by US residents(居民), the 285 miles flown on average by Germans, the 271 miles flown on average by those from the United Kingdom, and the 632 miles flown by the average Canadian last year.
China’s high total spending on international travel and its low average number of miles flown on international travel may show that while only a small percentage of China’s residents actually travel outside their homeland, and those who do spend a lot of money don’t go that far. But there are reasons for China’s low average of miles travel on international trips. A small percentage of Chinese now have enough money to travel internationally, though the number of people who do travel outside of China is growing fast every year. Besides, a large percentage of Chinese people traveling abroad stay close to home.
However, as more and more Chinese gain the financial ability to travel internationally and as Chinese become more and more interested in visiting destinations farther and farther away from home, their spending on international travel and the average distances flown will both rise rapidly.
1.Why does the author suggest learning Chinese for the future work in travel industry?
A.Being good at Chinese is a must for future work.
B.Chinese is most commonly used in travel industry.
C.Travel industry requires employees to learn Chinese.
D.China is a big-spending nation in international travel
2.What can we infer from paragraph 3?
A.People from different countries have different preferred destinations.
B.China has a relatively low average number of miles flown on travel.
C.Chinese people are more willing to travel abroad compared with Canadians.
D.People going on a journey around the world hate taking international planes.
3.What are many Chinese people who travel abroad likely to do?
A.Try to save their money. B.Improve their ability to travel.
C.Choose to stay close to home. D.Travel in America and Germany.
4.What does the last paragraph say about the future of Chinese people’s traveling abroad?
A.It’s bright. B.It’s confusing.
C.It’s hopeless. D.It’s unclear.
