Stephen Hawking has said he believes brains could exist independently of the body after people die, but that the idea of a conventional afterlife（传统意义上的死后重生）is a fairy tale. Speaking at the premiere（首映）of a documentary film about his life, Stephen Hawking said: “I think the brain is like a program in the mind, which is like a computer, so it's theoretically possible to copy the brain onto a computer and so provide a form of life after death.”

    “However, this is way beyond our present scientific and technological level. I think the conventional afterlife is a fairy tale for people afraid of the dark.” The author of “A Brief History of Time”, who earlier approved of the right for the deadly ill to end their lives as long as safeguards were in place, suffered from motor neurone(运动神经元) disease at the age of 21 and was given two to three years to live.

    “All my life I have lived with the menace of an early death, so I hate wasting time,” Hawking said on Thursday night, using the computer-created voice he controls with a facial muscle and a blink(贬眼) from one eye. The documentary explores a brilliant schoolboy with unclear handwriting who enjoyed the life of Oxford University before illness led to a lifelong desire of discovery about the origins of the universe, which began as a graduate at Cambridge University and has shocked the world.

    Hawking's sister Mary says in the film that her brother was highly competitive and curious about everything in a household which friends described as very academic, and explains how she received a toy house as a present when they were children, to which Stephen immediately added electricity.

    She said that life with her brother was attractive and exciting. “It's a waste of time arguing with Stephen because he always manages to turn the argument round,” she said. The film goes back to his childhood and his student days and shows the scientist, who uses a wheelchair, at home with break. It also explores his family life with his first wife, Jane, and their three children, the breakdown of their marriage and his marriage to one of his carers.

    Jane appears on camera to explain how the pressures of caring for the children and the increasingly disabled Hawking became even worse once full-time nurses were brought into the home, destroying any privacy（隐私）. His second wife and former nurse, Elaine Mason, does not appear in the film, and Hawking introduces their 1995-2007 marriage with a few pictures and a brief description.

    It's common knowledge that some countries have higher life expectancies than others, but the city you live in can also affect your health.

    Some cities are hard on their residents. In places with poor city planning, for example Lagos, which was called out recently by the Economist Intelligence Unit, public spaces are few, making outdoor activities hard. Lack of infrastructure (基础建设) blocks the streets with cars and the air with pollutants, and residents work long hours for little money.

    These are just some of the factors added up by Spotahome, a rental agency. They've analyzed data from a range of sources, including the World Health Organization, TripAdvisor and the CIA World Factbook to score each city on health, gym availability and quality, life expectancy, obesity, green space and other elements to make a list to work out which are the world's healthiest cities.

    The list is certainly Euro-centric and sunshine is seen as a positive factor. It does go some way towards suggesting which cities are getting it right in providing a good life for their residents. It may not be surprising to learn that most of the healthiest cities are in northern Europe, known for its people-first approach to city planning. The cities of Australia and Canada also do well. However, the first American city is only in 34th place. The UK doesn't fare too well either-its only city in the top 50 list is London, in 40th.

    Whether you're planning a wholesome holiday, or simply wondering what your city can do better in its quest for happy citizens, the list of the 50 healthiest cities will give you pause for thought about the future of city planning. Here are the slender, healthy-eating, clean-aired cities that are getting it right.

    When I was a boy, my parents and I traveled from New York City to the Pennsylvania countryside for a weeklong taste of rural life. We stayed in a guesthouse on a farm, joining the daily routines and eating meals with the farmer and his family. We got up early to see the cows as they were milked. I even tried my hand at milking one, and then joined the farmer as he released the cows into the field afterward.

    Decades later I still have vivid memories of that trip which made me realize the value of a vacation, of seeing new things, meeting new people and sharing memorable experiences with family members. To this day, I still consider that family trip when I plan to take time off with my wife and kids. Vacations are a time for resting and connecting. As a bank manager, I spend much of my workday encouraging my customers to save their money. One of the reasons I give is that we should all have enough for a family vacation every year. In our busy lives, family is what we should be saving our money and time for.

    For my family, our vacation starts when we begin planning the trip. We talk about destinations and our budget (预算) ahead of time. Among the things we discuss: Can we save money by renting a house instead of spending six nights in a hotel? Would it be better to buy groceries and cook for ourselves rather than eat out every night? Involving (使参与) the kids in planning the vacation makes sure that they have a great vacation too. I prefer to visit historical sites and museums while they love to fish and swim. So I build in some relaxation time for us all so that the vacation can work for everyone.

    Each year, setting aside vacation time to spend together is especially important to us. A relaxing environment opens the doors to all kinds of conversations—deep, silly or meaningful. There's no pleasure from the usual everyday tasks. What matters is that everyone is having a great time.

    One day when I was 5, my mother scolded (责骂) me for not finishing my rice and I got angry. I wanted to play outside and not to be made to finish eating my old rice. When angrily opening the screen door with my foot, I kicked back about a 12-inch part of the lower left hand corner of the new screen door. But I had no remorse, for I was happy to be playing in the backyard with my toys.

    Today, I know if my child had done what I did, I would have scolded my child, and told him about how expensive this new screen door was, and I would have delivered a spanking (打屁股) for it. They never said a word. They left the corner of the screen door pushed out, creating an opening, a breach (裂缝) in the defense against unwanted insects.

    For years, every time I saw that corner of the screen, it would constantly make me think about my mistake. For years, I knew that everyone in my family would see that hole and remember who did it. For years, every time I saw a fly buzzing (嗡嗡) in the kitchen, I would wonder if it came in through the hole that I had created with my angry foot. I would wonder if my family members were thinking the same thing, silently blaming me every time a flying insect entered our home, making life more terrible for us all. My parents taught me a valuable lesson, one that a spanking or stern (严厉的) words perhaps could not deliver. Their silent punishment for what I had done delivered a hundred stern messages to me. Above all, it has helped me become a more patient person and not burst out so easily.

    Nola (August 21, 1974-November 22, 2015)was a northern white rhino(犀牛) who lived at the San Diego Zoo Safari Park near Escondido, California. At her death, she was one of only four remaining northern white rhinos in the world. The other three lived in Kenya. World Rhino Day, held on September 2, is to raise awareness(意识) of the less than 30, 000 other rhinos left on Earth.

    "Rhinos need our help today, not tomorrow," Nola's lead keeper Jane Kennedy said. "Last year we lost over 1, 200 rhinos just in South Africa. If we continue to lose more than 1, 000 rhinos a year, in 10 to 20years all the rhinos on the planet will be gone. "

    "Unfortunately, most animals are in danger of dying out because of humans," Kennedy says. "Humans have either poached animals, or because there are over seven billion of us, we've taken up too much of the world's resources". Poachers illegally hunt rhinos for their horns. They sell the horns for thousands of dollars per pound, to be used for art, jewelry, and decorations. Experts believe that one rhino is poached every eight hours.

    In 1975, the San Diego Zoo Institute for Conservation Research started the Frozen Zoo, a program through which researchers have collected cell (细胞) samples from more than 8, 000 different types of animals, including the northern white rhino. Scientists hope that by studying the rhino cells, they will get greater understanding of it, and will find ways to increase its numbers.

    Jane Kennedy describes World Rhino Day as "a celebration of rhinos along with an awareness campaign(活动)for everybody across the world to know that rhinos need our help. "At the San Diego Zoo, children and adults are welcome to visit and speak with zookeepers to learn about rhinos. But you don't have to live in San Diego to celebrate World Rhino Day. It is observed around the world, with zoos and wildlife parks holding special events and programs to teach people about rhinos, and enable them to see the animals up close.

Nowadays, for many people, buying a house or flat is just too expensive. However, the total amount of rent paid by tenants in Britain in 2017 rose to more than 50 billion-more than double the level of ten years prior. Consequently, a lot choose to share the flat.{#blank#}1{#/blank#}

The pros? People rent a room and share the kitchen, living room and bathroom to save money.{#blank#}2{#/blank#}You may not even need to ask; just leave an IOU. Additionally, there's the fact that you gain access to their social networks. Living with people means meeting their friends, who may then become your friends.{#blank#}3{#/blank#}Due to the nature of communal living, you're not just dealing with your own life events. Most likely, there will always be a shoulder to cry on when you need one. But don't forget to pay back when they need it.

Now the cons.{#blank#}4{#/blank#}In most cases, the kitchen, for example, will be divided up into designated shelves and areas. Worse, many people may not respect these boundaries. You might well come home to find someone steal your milk or shower gel, and no one owns up to it. Furthermore, there are the unexpected guests. If a flatmate forgets to keep you informed of a party they're throwing and it can be challenging for you to have a quiet night.

{#blank#}5{#/blank#}Some people prefer their own space while other s thrive in a social environment. Regardless, for many who lack the means to buy their own property, a flat-sharing is, and will continue to be, a necessity.

A. Lastly, there's the emotional support.

B. Those flat-sharing can share the secrets.

C. To start with, do you lack private space?

D. There's limited storage space, for a start.

E. Whether the pros outweigh the cons depends.

F. Then what are the pros and cons of flat-sharing?
