3D printing is becoming more and more popular. We are now able to create things we need very quickly and easily using 3D printers. But can you imagine printing food?
Some scientists are trying to revolutionize the dining experience by doing this. They hope that having a 3D printer in the kitchen will be as common as the microwave oven or blender.
Scientists say that it’ll be quite easy: you simply have to select a recipe and put the raw food ‘inks’ into the printer. You can also modify the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and nutritious meals.
Using 3D printers to create your meals would also be saving the environment. There would be less need for traditional growing, transporting and packaging processes as food production would be a lot more efficient. For example, alternative ingredients(原料) such as proteins from algae, beetroot leaves and insects could be converted into tasty products.
Printing food could also help people who suffer from dysphasia (a swallowing disorder). They could program the printer to print softer versions of their favorite foods so that they would not have trouble in swallowing them.
However, some people think that a future of 3D food printing would be a disaster. It could take away many jobs, including those fro growing, transporting and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes could be printed from a raw “food ink”. Likewise, traditional cafes and restaurants might lose business. Also, there are concerns about the nutritional value of printed food: is it really possible to be get the nutrients we need from food –based inks and gels(凝胶)?
What’s more , cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pleasure of cooking is dead and meals can be created at the touch of a button.

Natalie Trayling is a famous street artist in Melbourne. At first, those who happened to pass by her and spare some change didn’t even realize what a musical genius was playing. The emotional tune was not only masterfully played but also composed by Natalie herself when she was only 14. Gradually, as long as she appears, people will stop, absorbed in her music. Her music makes you think about calmness, the good things in life, and never giving up.
But what people do not know is that behind the beautiful music of the old woman, it is full of bitterness. At the age of 12, she won a music scholarship at Santa Maria College. At 15 she knocked back a scholarship to the Royal Academy of Music in London because her parents couldn’t pay non-tuition costs. When she left school, she taught piano at Santa Maria. Later she met her husband, Denis. They had four children, but the two of them died. In 1984, Denis asked for a divorce. Natalie’s son, Nathan, was given medication for depression. Natalie lived either outdoors in Royal Park or in boarding houses for nine years. In late 2003 Natalie collapsed with anaemia(贫血) and was hospitalized for six months.
For half a century, Natalie has been teased by fate. But even so, she never gave up her love for music. When asked why the music was so important to her, she said: “Music is everything. I do feel part of it. The whole world is music.”
When Natalie went on the Internet, she became a sign of Melbourne. People are impressed by her persistence in dreams and the optimism of life. Now she is no longer wandering around. She can play the piano at any time, but as long as the weather is good, she will walk to the streets of Melbourne, and play a touching melody for the rush of the city.

Four apps for students to learn English
Quizlet
Quizlet is a learning app---a computer program you use on your mobile device. It can help users build and test
their knowledge of English words and terms. Quizlet has word sets for millions of subjects. And, it is quickly becoming a useful mobile tool for language learners.
Socrative
In Socrative, teachers can create timed learning games. In class, students compete individually or as part of a team against classmates. One game students love is called space Race. In this game, if a team answers a question correctly, their rocket moves forward. This team whose rocket gets to the end first wins. Also, teachers can use Socrative as an “exit ticket,” a question they can ask students about what they learned in that day’s class. Students write their answers on their mobile devices. Then, the teacher can show the answers on a shared video screen.
QR Codes
A QR Code is a kind of sign that a smartphone can read with its camera. When your phone camera reads a QR code, it takes you to a website, image, video or anything you want to share. For example, one will take you to the VOA Learning English website.
Evernote
Evernote lets users store and share notes, images and recordings in one place. Teachers can also use Evernote to give homework.

It was a cold December day． After saying goodbye to his neighbor， David， Tom set out for a run with his dog， Taz．As a professional athlete， Tom often went for training runs by himself， and had done this particular route many times before， but that day something unusual happened to him．
About an hour later， Tom hit some black ice． He found himself slipping down the rock face， which became steeper and steeper （陡峭的）until suddenly he was in free fall． He fell 60 feet into the canyon （峡谷），landing on grass and dry branches． If he'd missed them， there was no way he would have survived． He could feel his legs，so he knew he wasn't paralyzed （瘫痪的），but he was in great pain． Taz had managed to find his way back to Tom， so Tom knew there must be a way out of the canyon， but he couldn't stand or even crawl （爬行）． He later learned that he had broken his pelvis （骨盆）．
Tom shouted for help， and tried to pull himself forward． Every inch was an effort． It took him five hours to go a quarter of a mile． Eventually it got so dark that he couldn't see where he was going． He decided to stay next to a river which he could drink some water from． All he had on him were his jogging clothes， a water bottle， two boxes of medicine， a bar of chocolate， and a shower cap which adventure racers often wear to prevent heat loss．
At night， the temperature dropped below freezing． Tom couldn't go to sleep or he would die， so he stayed awake lifting his head a few inches，over and over． Throughout the night，Taz curled up next to him and kept him company． The next morning， he couldn't move any more． He tried to stay positive． He was sure somebody would find he was missing or hear him screaming for help． But there was nobody around．
