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.

    One night, the first floor of the house suddenly caught fire. The fire was big, and soon became a sea of fire. On the second floor lived a little girl and her grandmother; the little girl's parents had died, and she lived together with her grandma. In order to rescue the little girl, the grandmother was burned to death, leaving the little girl crying for help loudly.

    How could people enter the house? At the very moment, a man carrying a ladder rushed to the flames and entered the house through the window. When he appeared again in the eyes of the people, the little girl was in his arms. He gave the child to the crowd, and then disappeared into the night.

    This little girl had no family. Two months later a meeting was held to find a person to adopt the girl. A teacher was willing to adopt this child, and said she could give her the best education; a farmer wanted to adopt this child, saying that village life would let the child grow up healthily and happily; a rich man said, “I can give the child everything that others can do.”

    A lot of people who wanted to adopt this child said a lot about the benefits of their adopting the child. But the little girl's face had no expression. At this time, a man, through the crowd, walked straight to the little girl, and opened his arms for the little girl. People were puzzled, and they found that the man had terrible scars on his arms. The little girl let out a cry, “This is the man who saved me!” She suddenly jumped up and buried her face in his arms and sobbed. Naturally the man adopted the girl.

    Feet help us walk, run, dance, and jump. The words feet and foot are also used in everyday speech.

    To be under someone's feet means to be troublesome. In other words, you are standing too close to someone and are getting in their way. Some adults criticize (批评) children for being under foot.

    Speaking of children, if someone says their home will soon have the pitter-patter of tiny feet, it means the family is expecting a baby!

    Now, people who are active do not let grass grow under their feet. They are never in one place for very long. People who can think and take action at the same time are said to be able to think on their feet.

    Some people appear to have it all. They have money, a good education, good looks, a great family and a large circle of friends. You could say they have the world at their feet. This means whatever they want seems to be there for them.

    People who have both feet firmly on the ground are realistic and practical. They are not dreamy. You might say such a person is well grounded. If you are a bad dancer, you might be described as having two left feet. To dance well, it is better to have a right foot and a left foot.

    Sam loves skiing. He thinks that it would be fun to own a ski resort (滑雪场) high in the mountains. But he knows nothing about running a business. So, he decides to get his feet wet. In other words, he wants to get used to a new situation.

    He joins an organization for resort owners and attends their meetings. He travels to ski areas all over the United States. This helps Sam get his foot in the door. Having a foot in the door is a starting point. This expression comes from people selling things door-to-door. They would block the door with their foot so people couldn't close the door on them.

    ①About 43.5 million Americans are taking care of aging relatives and friends, sacrificing(牺牲) time, money and sometimes their careers and personal health. They are doing the work of professional caregivers, who spend years training for the job. As baby boomers age, the demand for unpaid caregivers is rising. Meanwhile, the number of them is dropping rapidly thanks to smaller family sizes, higher divorce rates and increasingly demanding jobs. This November, actor Rob Lowe offered to tell his story and send some encouragement to the millions struggling to care for a loved one.

    ②I had my first experience with unpaid care giving fairly early. My father, Charles, was diagnosed(诊断)with lymphoma at age 50. I was 26. Luckily, he was financially successful and had a loving wife, my stepmother. It was challenging, but she was there from taking care of my father.

    ③In my late 30s, my mother, Barbara Hepler, was diagnosed with stage 4 breast cancer. That was when I was introduced to the front lines of what so many millions are experiencing. She did not have a husband or a significant other, so it fell to me and my two brothers to handle everything from her initial diagnosis to doctor shopping, treatment options, driving her to appointments and, finally, the end of life-which was profoundly difficult, obviously.

    ④At the time, I was starring in and producing a network television show, The Lyon's Den. It was fighting for its ratings life. If I took time off, the show would be canceled, I was responsible for 150 crew members, so I had to find a way to do both.

⑤Besides, there is the negotiation of medical coverage, which requires phone calls, weeding through paperwork and talking to insurance companies and doctors. I remember thinking, Jesus Christ, if I were sick and had to do this on my own? I don't think I could get out of bed in the morning.

    ⑥The people we are talking about-the friends and family members who are out there doing important work-are unpaid. Watching a loved one go through an illness, possibly ending in death, is stressful and depressing. Add economic and scheduling burdens, and the load for caregivers is heavy. To them I say, "Don't forget about yourself. When you get on an airplane, the crew says, Secure your own mask first before helping others.” Why? Because without you taking care of yourself, you can't take care of anybody else. That's why I've partnered with EMD Serono andEmbracingCarers.com, where you'll find invaluable information regarding everything you'll be, or are, going through.

    Most people agree that being a good driver means being safe and not aggressive on the road. One debate some people still argue, however, is who drives better: men or women? Although it's impossible to say that one gender drives better than another definitively, there are some noteworthy trends.

    Male drivers tend to have more accidents

    Data from the Insurance Institute for Highway Safety (IIHS) shows that male drivers tend to have more total accidents than females. The IIHS, an independent non­profit devoted to reducing car accidents, also found that 71 percent of all motor vehicle crash deaths in 2017 were males. Although the gap has narrowed, almost every year from 1975 to 2017, the number of male crash deaths was more than twice the number of female crash deaths, per the IIHS.

    Women might be less­confident behind the wheel

    Although male drivers have more accidents, other research shows women aren't "perfect" drivers, either. Researchers from the University of Michigan's Transportation Research Institute studied traffic accidents over 20 years and found that female drivers are more likely to run into a car driven by another woman than a man. The study, however, doesn't explain possible reasons for this pattern.

    One that they might consider testing in the future is that some research also shows women are less­confident behind the wheel than men. A study from UCLA exploring the relationship between new drivers' skills and different variables, including gender(性别), shows female students were less confident drivers than men.

    So are men better drivers than women?

    Gender is just one factor when it comes to safe driving, along with others such as age, and even the time of day people drive. One study shows that both genders have a greater accident risk when driving at night, but males still have a higher risk at all times of the day. Driving quality also changes based on location, too, as some states are more dangerous than others. Data from the National Highway Traffic Safety Administration shows that Wyoming, Mississippi, and Montana have high accident death rates, without regards to gender. It goes to show that everyone should learn and practice safe driving habits instead of worrying about who drives better.
