Claire Metcalf
“The concept is great, but the staff are the ones who really make it.” she says. “It takes a lot of discipline to always be friendly, but the staff at Staybridge Suites do that. They genuinely care about you. ”
Andrew Roberts
“One of the best things is having my own kitchen. I often end up working late and I don’t fancy eating in a restaurant on my own, so cooking for myself is a big drawcard. ”

Pauline Robinson

Ryan Ruckledge
“The fully-equipped kitchen is great. I always have a one-bed apartment so I have a separate kitchen and dining room and I’m able to relax and cook some meals. Eating out can feel a bit much when you do it day in and day out—it makes you hate what you do—and I don’t want that.

When riding enthusiast Nina lost the use of her legs, it looked as though sh e’d never be able to enjoy her favorite activities again. Elizabeth, a competition gymnast, says she attempted suicide after an accident left her disabled. Tim lost both legs serving in the Middle East and figured he’d never be able to ride trails with his wife the way they used to.
But John Gray, a master saddle(鞍)maker in tiny Horseshoe Bend, Arkansas, put them all back in the saddle. “I consider it a privilege to watch people achieve their goals,”he says. “And I consider it an honor that I can help. ”
John followed in his father’s footsteps in t he saddle making business, but he learned how to fashion therapeutic(治疗的)ones by trial and error. At first he simply adapted standard models, until he found a saddletree maker willing to customize(定制)the frame to meet the needs of each rider.
Many of John’s saddles have backrests and seat belts. For Tim, he made a bucket seat similar to an old-fashioned sidesaddle. A rider who wanted to ride in the Mardi Gras parade needed a saddle with head and chest restraints. Each story is different, but they all touch your heart. All these riders have come through life-changing experiences with the determination to keep doing the things they love.
Elizabeth raised the money to pay for her saddle by getting several country music personalities to sign a guitar, then selling it. Nina is competing in shows again—after helping to start a show class for disabled riders. “Help me onto my horse, and I can take it from there, ” she says.
“I’m so happy I could help.”John adds. “Nina has always been a good rider, and her di sability hasn’t slowed her down.”

C. John is doubtful about the future of his saddles.
D. John’s saddles are changing the lives of disabled people.
C
If a stranger offered you money to keep a suitcase in your spare room, would you accept? How about the other way round: if you had too many belongings, would you consider trusting someone you met online with their safekeeping? Anthony Paine believed enough of us would answer “yes” to these questions to launch his own startup(新兴公司), Stashbee. His business links people with space to those who need it.
And it's just one player in the booming “sharing economy”, an industry that relies on people renting out things like their beds, bikes and even parking spaces. Airbnb, a company valued at 200bn RMB, provides a platform for those renting property short-term. DogVacay pairs holidaymaking pet owners with pet-friendly hosts, and aims to be profitable by 2017.
All their business models revolve around one simple word: trust. So, how does Stashbee measure up? BBC journalist Dougal Shaw decided to try it out for himself. He had some odds and ends to store while renovating his house, and met a host through the site who could keep them for 475 RMB for two months. All were relatively smooth and painless.
Heavyweights(行业巨头)in the traditional storage industry, such as Big Yenow and Access, aren’t convinced. A representative from Access told Shaw he was skeptical about storing with “amateurs”. He considered 24／7(全天候)access to the items and better security as the main advantages of his service.
Stashbee agree that dealing with security concerns is important, but say business success
depends more on people overcoming a distrust of strangers we’ve been taught since childhood. They aren’t alone. Companies such as Costockage, Roost and Spacer all run similar storage businesses, and are all relying on a shift in consumer attitudes.
And the concept of social storage doesn’t stop there. CityStasher beli eve there’s a gap in the market for those who want to store things for extremely short periods of time.
Would you try it out? It’s a question of trust.
29. The author put forward two questions at the beginning of the text to__________.
A. expect readers to answer them
B. carry out a survey among readers
C. start a conversation among readers
D. draw readers attention to the topic
30. How does Dougal Shaw try out Stashbee’s business?
A. Experiencing in person.
B. Doing a survey online.
C. Analyzing some data.
D. Exchanging his belongings.
31. What does the traditional storage industry value most?
A. Trust.
B. Security.
C. Cost.
D. Professional knowledge.
32. What can we infer from the text?
A. Trust is not well built in childhood education.
B. The new startup isn’t concerned about security.
C. No company follows the business model of Stashbee.
D. Consumer attitudes have changed greatly over time.
D
The “Take In” restaurant in Helsinki, Finland, is currently in the news for its ingenious(有独创性)service. Instead of cooking the meals in its own kitchen—which doesn’t exist—it allows customers to order various dishes from a selection of 20 other restaurants in the city.
Sponsored by American Express and Wolt, a popular food delivery app, Take In is a pop-up restaurant that opened at the beginning of November 2016, and will run through May 12, this year.
As you’ve probably already guessed, the name “Take In”is a clever play on words like take-out. The whole point of ordering take-out is to avoid going to a restaurant, and if you’re going to dress up to go out, you might as well go straight to your favorite restaurant instead of ordering food from it somewhere else. But here’s the idea behind it—when you go out with a group of friends and you can’t decide where to go for dinner, because everyone wants to order
something else, Take In is the perfect solution.
“We want to be a living room in the city,” a Wolt spokesperson told Monocle magazine. “We all know what it’s like when you’re about to go out for dinner with a big group of friends. Everyone wants to order what they like. What are you going to do? Well, the answer in Helsinki right now is that you come to Take In because you can do all of those things in the same place. ”
Customers are more than welcome to stick to the selection of drinks available at the bar. But if they want to try the “take in” experience, all they have to do is use the Wolt app, just as they would from the comfort of their own homes. Once they order and pay for their meals, all they have to do is wait for someone to deliver it to the pop-up restaurant.
33. What does the text mainly tell about?
A. American Express and Wolt.
B. The “Take In” restaurant in Helsinki.
C. The way to order “take-out”.
D. A world-wide food service.
34. Why is the “Take In” restaurant popular with people?
A. It can satisfy the taste of different people.
B. People can pay less money.
C. People can get together with best friends.
D. It can cook different meals.
35. What do we know about the “Take In” restaurant?
A. It has been run for more than two years
B. It will replace “Take out”restaurants soon.
C. You should use the Wolt app.
D. You can enjoy the service in your own living-room.

Is it necessary to learn when we are 50s, 60s or even 70s? Most people consider when they get retired, they are supposed to be completely laidback, do something fun, or hang around. 36 It’s particularly important to the elderly.
Through learning, we know how to think, how to memorize, how to ask questions and even how to interact with others. According to a study, while we are learning, “the brain creates neural(神经)pathways”that make us smarter. 37 The more we learn, the more new neural pathways develop in our brains.
When it comes to learning, it doesn’t mean we must load ourselves with lots of knowledge. What we need to do is just learn something we like day in and day out. 38 Everyone learns from bottom to up. If we have an interest to learn, that desire will naturally push us to move forward.
As we feel worn out from learning, don’t be discouraged. 39 An old saying go es,“Birds of a feather fly together. ”As long as we have partners to learn all together, our learning excitement will come alive again. On the contrary, if we don’t learn, and choose to distance ourselves from others, we might be getting dumb, and slow; eventually, we lose energy, and life passion. Instead of being bored, dumb, why don’t we keep learning?
40 More importantly, learning explores our life horizon, helps us build up our confidence; gradually, it leads us to a way of finding a sense of value and achievement in the process of learning journey.
A. It’s never too old to learn.
B. Don’t worry if we cannot learn well.
C. You should set a high learning target.
D. Learning makes us understand how potential we are.
E. Look for a partner who has the same common interest as you do.
F. In other words, our brains are active as we learn something new.
G. However, the truth is that learning makes us energetic, and self-fulfilled.

Dear Charlie，
I’m glad to hear that you are learning Chinese culture in Confucius Institute．
Mencius’Mother Moving Three Times tells about how Mencius’ Mother moved again and again to provide her son with a good study environment, because her son was so much influenced by the people in the neighborhood. Finally they came to a place near a school. Mencius’ Mother was satisfied as the people living there were well educated. The story shows that the environment is very important for a kid’s study. And nowadays, people still value it a lot.
In fact, there is so much to learn about C hinese culture and I’m sure you can learn more if you come to study in China.
