A 13-year-old American has made a cheap machine that can help blind people read.
The blind can read by usingBraille– a system of small bumps (隆起物) that the blind touch to read the letters. The machine that makes these small bumps usually costs at least $2,000. It is called Braille writer. The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo – a combination (组合) of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine.
Banerjee designed (设计) his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee’s machine last November, but they did not say how much money they put in. Banerjee also got $35, 000 from his father to help him start the project. His father works as a computer engineer (工程师) at Intel. He spoke about why he gave so much money to his son, saying:”We as parents started to be interested more, thinking that he’s on to something and this invention has to continue.” Banerjee told the AP News: “My dream would probably be having most of the blind people…using my Braigo.”
1.What is Braile in Line 2?
A. A system of bumps to help the blind read.
B. The name of a new invention.
C. A very cheap machine.
D. A Lego robot.
2.How much will one save if he buys a Braigo instead of a usual Braille writer?
A. Over $2,000. B. Less than $350.
C. Exactly $35,000. D. At least $1,650.
3.What does the Braigo change into Braille?
A. Photocopies. B. Voices.
C. Electronic text. D. Computer languages.
4.Why did Banerjee design his invention?
A. He did it as a hobby.
B. Intel told him to do it.
C. He did it for a school science project.
D. He wanted to get money from his father.
5.Banerjee’s parents wanted him to continue to _______.

Recent development has made possible machines that print, cook, and serve a large number of foods. And the industry(产业) 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 Food printer to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to finish 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 world’s population(人口) is expected to grow to 9.6 billion by 2050, and some experts estimate (估计) that food production will need to be raised by 50 percent to keep present levels(水平). Sustainability is becoming a necessity. 3D food printing could probably help solve the problem. Some experts believe printers could use hydrocolloids (水解胶体) from rich renewable materials(原料) like algae and grass to replace(代替) the ingredients(烹饪原料). 3D printing can reduce fuel use and emissions(排放). The stores of the future might store "food" that lasts for years, freeing up shelf space and reducing transportation and storage requirements.
Nutrition(营养)
Future 3D food printers could make food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow customers(消费者) to print food with customized(定制的) 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(要求).”
Challenges
Though there are great developments in 3D food printing, the industry has many challenges to overcome. Most ingredients must be changed to a dry powder(粉末) before a printer can use them, and the printing process takes a lot of time, because ingredients interact (相互作用)with each other in very complex ways. Besides, most of the 3D food printers now use only dry ingredients, because meat and milk products may easily go bad. Some experts doubt about 3D food printers, believing they are more suitable for fast food restaurants than homes and high-end restaurants.
1.What advantage(好处) does 3D printing bring to food production?
A.It teaches cooks to create new dishes. B.It saves time and effort(努力) in cooking.
C.It improves the cooking conditions. D.It helps to decorate the restaurants.
2.What does the underlined word “raise” mean in paragraph 3?
A.募集 B.导致 C.培育 D.增加
3.According to Paragraph 4, 3D-printed food ________.
A.is easier for consumers to get B.can meet personal nutritional needs
C.is tastier than food in supermarkets D.can keep all the nutrition in raw(生的) materials
4.What is the main factor(因素) that prevents 3D food printing from spreading widely?
A.The printing process is not long. B.3D food printers are too expensive.
C.Food materials have to be dry. D.Some experts doubt 3D food printing.
5.What could be the best title of the passage?
A.3D Food Printing: Delicious New Technology B.A New Way to Improve 3D Food Printing
C.The Challenges for 3D Food Production D.3D Food Printing: From Farm to Table

Nora, a 17-year-old American, notices that when she has to do a paper for school and researches it on the Internet, she rarely reads a whole page and does deep reading. “I’ll read the beginning of a paragraph and then I'll skip(跳过) the rest,” she says.
While Nora's mother, Martha, loves sitting down with a good book and reading carefully, her daughter may be the wave of the future.
“Deep reading”, or slow reading, is a process in which people think carefully while they read. With most, that means slowing down --- even stopping and rereading a page or paragraph to really understand what the author is trying to say.
Last summer, Google CEO Eric Schmidt said he was concerned about what he sees as a decline（衰退）in slow reading. Instant messages and 140-character tweets（微博）appear to be reducing out ability to concentrate on a single idea or theme of a book, he told Foreign Policy Magazine.
It's easy to forget the benefits of deep reading in an age when anything worth doing is done fast. Experts warn that without deep reading, it is impossible to be an educated person of the world, a knowledgeable voter or even an imaginative thinker.
“If you want to have a deep relationship with a text and understand a complex idea, then slow reading is a preferred style. It is good for pleasure, too. It is not a rushed experience and you can lose yourself in a text,” said Canadian writer John Miedema, the author of the book Slow Reading.
US' Ohlone College English professor Cynthia Lee Katona says reading is a highly social activity that builds the mind and social connections. If you read, she says, you simply know more and have more to talk about with friends, partners and people you know.
Deep reading can also take a reader on a trip around the world even if they are sitting in a living room armchair, Katona says. Also, deep reading helps people develop thinking, writing and conversation skills.
“If you like beautiful things, authors put words together that are really beautiful and expressive,” she says. “If you want to write well--- and there are lots of reasons to express yourself clearly --- you should read.”
1.The comparison（对比）between Nora and her mother's reading habits _______.
A. introduces the wave of future
B. adds a lot of fun for readers
C. explains what deep reading is
D. calls attention to deep reading
2.What leads to the decline of deep reading, according to Eric Schemidt?
A. The fast pace of modern society.
B. The lack of desire for knowledge
C. The weakening ability to concentrate.
D. The wide use of instant messages and tweets.
3.What does the underlined word “it ” refer to in paragraph 6?
A. A deep relationship. B. A complex idea.
C. Slow reading. D. A preferred style.
4.According to the article, Cynthia Lee Katona's opinion of deep reading is that _______.
A. it makes sure you a better paid job
B. it makes you a better writer
C. it is better than travelling
D. it helps build better family relationship
5.What is the main point of the article?
A. The importance of deep reading.
B. How to improve reading skills.
C. The benefits of different reading styles.
D. The secrets of a knowledgeable person

Most of us have made an exercise plan， but only a few can follow it． WebMD（an American website） has listed the following tips for making exercise a habit in your life．
1.Do activities you enjoy．
Remember， there's no rule that says you have to go to a sports centre or buy equipment like swimming suits． Many types of activities， such as push﹣up（俯卧撑）， can be done whenever it is rainy or snowy．
2.Exercise after work．
Don't go home first． Few people are so motivated（有动力的） that they will go out again and exercise after they go home and change clothes．
3.Exercise even when you are tired．
Tiredness is not an excuse． While exercising， you breathe deeply and your body makes better use of the oxygen exchange． Then， you will feel energetic．
4.Notice that you are better than before．
It's great when your clothes fit better， you can lift heavier things or take exercise longer． There's something good too， like getting a good night's sleep or thinking more clearly．
5.Walk with a pedometer（计步器）
Not everyone can start out with 10，000steps a day． Use a pedometer， and find out your daily steps． And then， try your best to walk 300extra steps each day． Finally， you can reach 10，000steps a day．
阅读以上信息，用恰当的单词完成下面的短文，每空一词．
