Singapore is building an airport where indoor trees, waterfalls and a 'rain vortex' sit alongside check-in queues, waiting rooms and baggage carousels(传送带).

    Where once sat a car park, there will soon be thousands of trees and plants across 22,000 square metres of landscaped indoor parklands. This will be joined by a 40m-high indoor waterfall, expected to be the world's tallest. These are the plans for the new 3.5 hectare 'Jewel' development at Singapore's Changi Airport, scheduled to open in 2018; a five-story, 134,000 square metre complex, mixing natural outdoor plants with modern airport facilities.

    “The aim behind the introduction of such lush(茂盛的) landscaping is purely to provide all visitors with a memorable experience, one where they are surrounded by nature and greenery,”says Philip Yim, Chief Executive Officer of Jewel Changi Airport Development.

    Promised sustainability（持续性） measures include “extensive usage of photovoltaic panels（光电板）”to produce renewable energy, as well as encouraging the use of natural lighting and a “high efficiency” air-conditioning system.

    The indoor waterfall, named the “Rain Vortex”, will make use of special lighting effects to change at night into what is promised to be a dramatic light and sound show. “The Rain Vortex is one example of how sustainable design plays an important role in the planning of the attraction,” says Yim. 'In the event of a rain storm, the power of the rain water will flow naturally through the oculus. The excess rain water collected will be used for irrigation of the landscaping at Jewel.'

    Yim quotes the popular reputation Singapore enjoys as “the garden city”, where greenery is recognised as an essential part of the urban landscape, an attractive image which clearly inspires Jewel's design.

    However, it remains to be seen whether, beyond the aesthetic (审美的) appeal, Jewel can add genuine environmental things to something as un-environmental as an international airport.

    Taxi-booking app Uber agreed to sell its business in China to Didi Chuxing. The two firms had been fierce competitors, but Didi Chuxing had controlled the Chinese market with an 87% share.

    Uber China launched in 2014, but it had failed to make any profit for a long time. Cheng Wei, founder and chief executive of Didi Chuxing, said the two companies had learned a great deal from each other over the past two years in China. He added that the deal would set the mobile transportation industry on a healthier path of growth at a higher level. As part of the deal, Mr. Cheng would join the board of Uber, while Uber chief executive Travis Kalanick would also join Didi's board.

    Uber's China business would own its separate branding while US-based Uber Technologies would hold about 17.5% in the combined company. Didi Chuxing is backed by Chinese Internet giants Tencent and Alibaba.

    Uber had been struggling to break into the Chinese market despite having Chinese search engine Baidu as an investor. Last February, the company admitted it was losing more than $1 billion a year in China. “Funding their Chinese dreams was becoming too expensive for Uber,” Duncan Clark, chairman of Beijing-based consultancy BDA, told the BBC. Travis Kalanick said, “As a businessman, I've learned that being successful is about listening to your head as well as following your heart.”

    The fierce competition had led both companies to spend much more on their journeys. The combination is likely to see fewer such subsidies（补贴）. “One thing to watch carefully is how quickly consumers feel the impact as subsidies are withdrawn.” Mr. Clark added.

    The deal with Didi Chuxing came just days after China had agreed to provide a legal framework for taxi-ordering apps. Both Uber and Didi welcomed the decision. The new rules took effect last November and could, among other things, forbid such platforms to operate below cost.

    I have many new teachers in high school, but Lori Runkle, my English Language and Composition teacher, is my favorite teacher.

    Ms. Runkle enjoys getting to know more about students, so I have many chances to talk with her after class. I have always wanted to become a journalist (新闻记者). Since Ms. Runkle used to be a journalist back in the United States, she has introduced many helpful journalistic writing skills to me.

    Although she is my teacher, Ms. Runkle and I are more like friends. She often invites my classmates and me to take part in different activities outside of school. For example, I went to listen to a journalist's speech, which helped me better understand current events (时事).

    Not only does Ms. Runkle talk with me outside of school, she is also a great teacher in the classroom. English Language and Composition is a really hard subject for a second language learner. We felt worried in the beginning, but Ms. Runkle really makes an effort to help us out. In class, Ms. Runkle always encourages students to question everything to keep us active. One part of class I love the most is when groups of students are required to give speeches on events that are happening in the world. It requires a lot of deep thinking and I really learn quite a lot from it.

I love Ms. Runkle very much. She not only helps me to get good scores, but also acts as a good friend and always gives me advice on life.

    The year was 1932. Amelia Earhart was flying alone from North America to England in a small single-engined aeroplane. At midnight, several hours after she had left Newfoundland, she ran into bad weather. To make things worse, her altimeter (高度表) failed and she didn't know how high she was flying. At night, and in a storm, a pilot is in great difficulty without an altimeter. At times, her plane nearly plunged (冲) into the sea.

    Just before dawn, there was further trouble. Amelia noticed flames coming from the engine. Would she be able to reach land? There was nothing to do except to keep going and to hope.

    In the end, Amelia Earhart did reach Ireland, and for the courage she had shown, she was warmly welcomed in England and Europe. When she returned to the United States, she was honored by President Hoover at a special dinner in the White House. From that time on, Amelia Earhart was famous.

    What was so important about her flight? Amelia Earhart was the first woman to fly the Atlantic Ocean alone, and she had set a record of fourteen hours and fifty—six minutes.

    In the years that followed, Amelia Earhart made several flights across the United States, and on each occasion (时刻) she set a new record for flying time. Amelia Earhart made these flights to show that women had a place in aviation (航空) and that air travel was useful.

    When I was 8 years old, I decided to run away from home after a quarrel with my mother. With my suitcase(行李箱) packed and some sandwiches in a bag, I started for the front door.

    My mom asked where I was going. “I'm leaving home,” I said.

    “What's that you're carrying?” she asked.

    “Some clothes and food,” I replied.

    “If you want to run away, that's all right,” she said. “But you came into this home without anything and you can leave the same way.”

    I threw my suitcase and sandwiches on the floor and started for the door again.

    “Wait a minute,” Mom said. “You didn't have any clothes on when you arrived, and I want them back.”

    This infuriated me. I tore my clothes off — shoes, socks, underwear and all — and shouted, “Can I go now?”

    “Yes,” my mom answered, “but once you close that door, don't expect to come back.”

    I was so angry that I shut the door forcefully and stepped out of my home. Then I noticed down the street two neighbor girls walking toward our house. I was so shy that I saw the big spruce (云杉) tree in our yard and jumped under the low-hanging branches (树枝). A pile of dried-up brown needles (针状物) were beneath the tree, and you can't imagine the pain those sharp needles caused to my body.

    After I was sure the girls had passed by, I ran to the front door and knocked at it loudly.

    “It's Billy! Let me in!”

    The voice behind the door answered, “Billy doesn't live here anymore. He ran away from home.”

    Looking behind me to see if anyone else was coming down the street, I said, “Mom! I'm sorry. I'm still your son. Let me in!”

    The door opened and Mom's smiling face appeared. “Did you change your mind about running away?” she asked.

    “What's for supper?” I smiled back.

    A body image is the way a person views his or her body. It affects how a person “feels” about his or her body. For example, when not looking in a mirror, people have a sense of what their bodies look like. A positive body image is having a realistic and accepting view of your body. However, very few women have a positive body image. Society, dieting, eating disorders, and overweight are all related to a negative body image.

    A century ago, full and curvaceous (曲线美的) bodies were admired. They were also more natural for women to keep. Nowadays, the best female body has a tiny waist, flat stomach, thin legs, and is very slim. Women are told to weight less than ever before. Supermodels are the new women's idols. However, most of them are teenagers, and many of them have eating disorders or diet strictly. Trying to follow these standards is hard to most women. As a result, they starve themselves, or exercise—excessively (过度地), or both.

    Most women who know the standard of beauty and body weight are dieting to reduce weight and change their figures. Eating disorders are not simply unhealthy diet habits; they are considered as mental illnesses and can sometimes end in death. Strict dieting or food restriction combined with a negative body image can become an eating disorder.

    A negative body image can also lead to overweight. This is due to excessive eating to comfort bad feelings about their bodies. In addition, yo-yo dieting, which often follows a negative body image, leads to increasingly higher weights with each diet attempt.

    A negative body image is bad for women. I may help them to see an advisor who is good at treating women with negative body images. Lastly, if society worked on encouraging healthy lifestyles and healthy looking bodies for women, a lot of good would come from it.
