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 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 saves time and effort in cooking.
C. It improves the cooking conditions.
D. It contributes to restaurant decorations.
2.What can we learn about 3D food printing from Paragraphs 3?

Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer—but it can fly at a speed of 100mph and has a two-meter wingspan.
It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit” technique so the aircraft could be put together without tools in minutes.
No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “laser sintering (激光烧结)”and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.
Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”
The new printed plane is known as the Southampton University Laser Sintered Aircraft—or SULSA for short—and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.
1.Which of the following would be the best title for the text?
A. Revolutionary Breakthrough of 3D Printer
Scientists Create Aircraft with High Speed
C. New Designed Airplane with New Techniques.
D. The World’s first 3-D printed Airplane, SULSA
2.How could the plane work while flying?
A. It should be controlled by an autopilot system.
B. It should be controlled by “laser sintering”.
C. A pilot controls it using a remote control.
D. A pilot with high techniques controlled it.
3.This kind of plane has the following advantages EXCEPT ______.
A. it produces little noise while flying
B. it is manufactured in quite a short time
C. it only requires simple and cheap tools
D. it needn’t extra cost if changes are made
4.Professor Jim Scanlon believes they can _____ with their techniques.
A.produce firmer and lighter real planes easily
B.connect and fasten tailor parts for real planes
C.copy earlier planes to study their techniques
D.find differences by studying the traditional ones

[1]There is a sign in the subway that explains New York completely. “NYC: tolerant of your beliefs, judgmental of your shoes.” We are open to many walks of life, but your shoes … well, that’s another story. Researchers at the University of Kansas say that people can accurately judge 30 percent of a stranger’s personality simply by looking at the person’s shoes.
[2]The study involved volunteers filling out a personality questionnaire and providing photos of ______that they most frequently wear. Then 63 students looked at the photos and were able to accurately guess the volunteers’ gender, age, social status, and even whether the owner was extrovert or introvert, liberal or conservative, and their degree of emotional stability and openness.
[3]Here are some interesting findings from the study. Practical and functional shoes generally belong to agreeable people. Ankle boots belong to those with more aggressive personalities. Uncomfortable looking shoes are usually worn by those with calm personalities. Those who are most worried about their relationships wear brand new or well-kept shoes. This is because they are worried about what others think of their appearance. Liberals wear less expensive shoes. The more boring the shoes are, the harder it is for the owner to form relationships. This is because he doesn’t care about what others think of his appearance.
[4] “Shoes convey a thin but useful slice of information about their wearers,” the researchers of the study said. “Shoes serve a practical purpose, and also serve as non-verbal cues with symbolic messages. People tend to pay attention to the shoes they and others wear.”
[5] The researchers noted that some people would choose shoe styles to hide their actual personality traits, but they also noted that volunteers were likely to be unaware that their footwear choices were revealing deep insights into their personalities.
1.What is the main idea of the text? (no more than 9 words)
2.What type of shoes do agreeable people favor according to this text? (no more than 5 words)
3.What can you know about a person if he often wears brand new or well-kept shoes according to this text? (no more than 10 words)
4.Fill in the blank in Paragraph 2 with proper words. (no more than 3 words)
5.What does the word “they” (Line2, Paragraph 5) probably refer to? (no more than 6 words)

Have you ever noticed that after about 6 months your perfectly new 1,000 dollar smartphone begins to slow down? What if I told you that it’s a sales strategy that pretty much all phone companies use to force people into buying new phones?
In late 2015,when Lisa Young was in charge of iOS security and beta software testing teams,her boss revealed a dark secret to her,saying that they were using a new strategy that would purposely slow down older phones every time the phone would upgrade to the latest opera ting system. This new method would force customers to buy the latest phone model,increasing sales by 70%.
She was a little disturbed to hear the news,but she just kept her head down and continued to do her job. After a while,the guilt of being involved with such a shady sales model started to weigh heavy on her. “How could a multi—billion dollar corporation continue to take advantage of the public like this?” she thought. In March of 2017,she contacted a reporter from CNN to finally leak the information concerning Apple slowing down phones.
The scandal(丑闻)went viral overnight,and every media outlet in the world,in every language was talking about it,making it one of the biggest controversies in consumer electronics history. A week later,she was secretly let go after her 8 years of service. Although she was taking a huge risk going against one of the most powerful corporations in the world,she felt a sense of relief exposing them. The public deserved to know and the fear became her motivation to find a way to destroy their shady sales model.
Several of her colleagues were fired with her. They quietly united,and after a year of extensive research they designed a unique product called Circa Charge that would reverse the negative effects of “software updates.” Phone companies have recently caught wind of their overnight success with CircaCharge and are trying to do everything they can to make this product illegal and ban it forever. Lisa and her team have ma de unbelievable progress in increasing battery life,battery health,and optimizing phone performance,and they will continue to develop new technology that will beat phone companies at their own game until they change their ways.
1.What can we learn about the new method mentioned in paragraph 2?
A. It is essential in the 1atest operating system.
B. It benefits users in upgrading their old phone.
C. It fool s customers into buying the latest model on purpose.
D. It is a successful sales strategy for advertising new soft wares.
2.What does the underlined phrase “kept her head down” in paragraph 3 refer to?
A. Lowered her head.
B. Nodded to show approval.
C. Pretended to know something.
D. Tried not to show she knows something.
3.How did Lisa Young feel after leaking the secret?
A. Disturbed. B. Relieved. C. Frightened. D. Disappointed.
4.From the passage,we know______________.
A. it's too tough for Lisa and her team to increase battery life
B. CircaCharge helps phone companies with software updates
C. Lisa struggles to force phone companies to change their current ways
D. phone companies find it essential to ban their illegal software for updating

As children begin to head back to school, there are several things that you can do to make sure that your child stays healthy and performs at their peak potential during the school year.
1.Make sure your child is up to date on their immunizations(免疫).The summer is a good time to schedule visits to the doctor’s as your child is not in school, and the visit won’t require that your child miss school days.
2.Encourage proper nutrition.America faces childhood obesity(肥胖).This means that the percentage of overweight children is increasing each year, and this will place your child at risk of developing a variety of diseases when they are middle age or even young adults.You can start helping your child to become healthier by offering fruits and vegetables at home instead of calorie heavy potato chips and candy.
3.Get your child involved in sports activities.Activities in high school such as track and cross-country are important for socialization for your child, as well as helping to improve their health.You can get your child interested in wholesome activities by discussing with them how you enjoyed similar activities in high school.
4.Have the birds and the bees conversation with your child.Many children become sexually active in junior school and senior high school, and the sooner you discuss sex with your child the sooner they will be prepared.Tell your child that there is always the possibility of infecting a sexual disease when two people have sex; and discuss with your child the use of condoms.The sooner you start having this embarrassing situation the better.
5.Know your child’s friends.You can do this by inviting your child to bring their friends over to your house for a pizza night, or by chatting with them when they stop by your house.If you find your child’s friend has a bad reputation, then you could consider introducing your child to a different network of people, such as through the girl/boy scouts.Forbidding your child from seeing a certain person may only lead them to rebel and become closer to that person.
6.Discuss with your child the seriousness of drug use and abuse.Your child may not realize that using drugs can have serious consequences.Your child may get the false impression that drug use is his right.Explain to a child that saying no to drugs is their right, and that anybody offering them drugs is not their friend.
7.Help your child to avoid a life long smoking addiction by discussing with them the consequences of smoking.The sad fact is that most smokers became addicted when they were in their teenage years, and are unable to quit for long periods of time and often die many years earlier due to their smoking habit which increases the risk of lung cancer, heart disease, and a variety of medical conditions.Even if you are a smoker yourself, you can discuss with your child about how damaging smoking can be on a person’s health.
8.Impress upon your child the importance of traffic rules.Tell them that it is OK to wear a seat belt in anyone’s car, because it may save their life one day.If your child rides a bicycle or a skateboard, then discuss with them the importance of always wearing a helmet.As you child becomes qualified for driver’s permit, you should discuss with them the importance of prevention from drinking and driving.
9.Be cautious about signs of depression in childhood.A surprisingly large number of children may become depressed, and a small number of teenagers and children commit suicide(自杀) each year.Realize that any signs of unusual depressed mood, angry outbursts, suicidal comments, feelings of hopelessness, and loss of enjoyment of activities with friends may be signs of depression.
