Some 30,000 years ago, artists who lived in caves in Europe painted pictures of the animals around them: panthers, hyenas, rhinos, cave lions, mammoths and other creatures which have been extinct for a long time. The paintings were highly realistic. Some even showed movement.

The artwork, more than a thousand drawings, is considered the oldest group of human cave drawings which have ever been discovered. They were preserved because the cave was sealed—closed off--for more or less 23,000 years.

    Fast forward to December 18, 1994, a group of French cave scientists were exploring caves in southern France. Jean Marie Chauvet, who led the group then, describes the process of discovering the cave paintings. “At that time I was in the front, Eliette just walked behind me, Christian behind. Eliette said she saw two marks with red ochre and she said, ‘They came here.' And at this very moment everything began. The drawings and everything linked to the parietal art(壁画). That is where it is tarted.”

    Cave art expert Jean Clotttes reviewed the paintings. “I was amazed at the number of paintings there were and paintings of their quality and particularly in front of the panel of the horses.”

    Scientific analysis confirmed the prehistoric date of the artwork. Studies showed the drawings were created tens of thousands of years ago, before human history was written. The United Nations' cultural agency UNESCO lists the cave as a World Heritage Site. They say that the drawings form a remarkable expression of early human artistic creation of grand excellence and variety.

    The Chauvet Cave has been named after the explorer who first entered it. However, its environment and drawings are too fragile to be visited by human beings. So the cave is closed, and only people there for scientific purposes can go inside and see the artwork.

    However, French authorities asked experts to create an exact copy of the cave, called Pont d'Arc Cavern. The copy, which we also called replica, cost more than 59 million dollars to build. It opened at the end of April in France.

    Pascal Terrasse is the president of the cavern. He says everyone will be able to experience the thrill of looking at drawings made by the first humans in Europe. He says the place is magic because it is done so well. Authorities say they think as many as 400,000 people will be allowed to visit Pont d'Arc Cavern every year.

    Dr. Michael Prager, a leading Botox expert, said that a growing number of women are developing something called “computer face”. He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls（颚骨下垂）,“turkey neck” and deep-set wrinkles（皱纹） on their forehead and around their eyes.

    The Botox expert said that, of all his clients, office workers were most likely to show premature （过早的）signs of aging. “ If you are one of the unfortunate people who frown（皱眉）while you are concentrating on the screen then, over time, you will inevitably（不可避免地） end up with frown lines.'' Dr. Prager said. “What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long. If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck.”

    Dr. Prager, who has a practice near Harley Street in London, said he encourages his clients（客户） to put a mirror next to their computer so they can see if they are frowning at the screen. “When people are stressed or thinking hard about something, then they will often put on agrumpy（脾气暴躁的）face' without even knowing what they are doing. When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them.”

    He said, “The women I am seeing at the moment have only been using computers at work for the last decade or so. But women in their 20s have grown up with them and use them for every single task. I think the problem is going to become much, much worse. In another ten years, they could be looking quite awful.”

    Dr. Prager said there were several simple steps which could avoid “computer face” such as regular screen breaks and stretching the neck muscles. And, of course, there was always Botox. He said that, after a couple of sessions of Botox, the habit of “grumpy face” could be broken.

    The wedding tradition of “something old, something new, something borrowed and something blue” has been around for hundreds of years. The tradition of carrying or wearing one of each item is said to bring luck and fortune to the newly married couple. Have you ever stopped to think what the saying really means? What is its origin and what does each item represent?

    The original saying dates back to the Victoria times and states, “something old, something new, something borrowed, something blue and a silver sixpence in your shoe.”

    Something old   A bride may wear or carry something old to represent her continued ties to her family and her old life. Many brides wear a piece of family jewelry as their old item. Some brides wear the wedding dress worn by their mother or grandmother. In many cases, something old may also be something borrowed.

    Something new   Wearing something new is supposed to represent success and hope in the bride's new life and in her marriage. If the bride purchased her wedding dress new, it may represent her new item, but any item that is new may be used. Something “new” is usually the easiest kind to fill.

    Something borrowed   The borrowed item should be something borrowed from a friend that is happily married. It is said that their happiness will rub off on you and bring lasting happiness to your marriage. Some brides borrow an item of clothing, a piece of jewelry, a handkerchief or perhaps a beaded(带珠子的) purse.

    Something blue Wearing something blue dates back to ancient times when a blue wedding dress was worn to represent purity, fidelity and love.

    Silver sixpence   Placing a silver sixpence in the bride's left shoe is said to be a symbol of wealth. This not only refers to financial wealth, but also a wealth of happiness and joy throughout her married life. Since most brides probably don't even know what a sixpence is, this part of the tradition is not used very often in modern times. However, if a bride would like to include it in her wedding, she can purchase a silver sixpence from many companies that sell bridal supplies such as garters(袜带) and invitations.

    In the future we might live somewhere other than Earth, like Mars. Some people ask how this will be possible. Well, Mars is in fact a lot the same as the earth. The days are almost the same as those on the earth. However, the two planets vary in temperature.

    Since there is mostly carbon dioxide on Mars, it would be quite difficult for a human to just land on it. So, special types of homes and space suits have to be designed. The space suits should be almost like the ones astronauts use now, and except that they have to be warmer so that the astronauts can survive the cold temperatures. The space suits must also be able to withstand (承受) high pressure and potentially dangerous radiation that can kill.

    The houses should be similar to our homes today with a slight difference. All of the houses and other buildings should be built inside a large dome (圆顶状物) or bubble. The domes should be made out of glass, and would also be able to prevent radiation from affecting the people inside. The domes will be connected to a machine (like plants which turn carbon dioxide into oxygen).

    With Mars' population growing, how would the people on its surface get fresh food and water? Just like humans use domes, they can also use domes to grow plants. However, the domes where the plants are grown must be built to expand. Once we upgrade the domes to a larger size then we can grow more food by cultivating (种植) more plants. To get the food or come in connect with other domes, there will be long narrow tunnels like roads that connect to each dome separating them by several doors so that the pressure in each dome can remain the same.

    On Mars, so many other things are available to us. As humans, we can have access to rare and fairly expensive metals that aren't very easy to get hold of on Earth, and a colony on Mars enhances (提高) our chances of finding these metals. So when someone here on Earth says that going to Mars is impossible, please tell them that they'll never know it until they try and they may try very soon. After all it's our future. Why not make it on Mars?

A Few Universal Truths to Transform Your Life

    Life is growth. If you are not reaching the kind of success, the following Universal Truths are just the ones that help to change your life for the better, regardless of where you are, where you've been, or what challenges you are facing. {#blank#}1{#/blank#}

    The best way to achieve your desires is to set a goal. Sometimes we find ourselves "spinning our wheel", struggling through a day-to-day routine that isn't getting us anywhere because we don't know where we want to go. {#blank#}2{#/blank#} Whatever the case is, figuring out what your goals are and whether your current actions are helping to achieve them is important.

    {#blank#}3{#/blank#} Setting goals is important but isn't enough to drive you to the finishing line; it's important, too, to be able to imagine yourself as the achiever of your goals. How will you feel? Why is it worthwhile to follow these goals and not some other ones? If goals are the final result of a journey, your vision(愿景) is the fuel to get you there.

    {#blank#}4{#/blank#} Whether you regard yourself as a towering tree or a blade of grass, or whether you think you are a high mountain or a small stone, you represent a state of nature that has its own reason of existence. If you truly admire yourself, you'll be courageous.

    There is no better time to begin than now. {#blank#}5{#/blank#} But the truth is that your time is now. No matter what dream or desire you have, you are likely not to have more time in your life to make it happen.

A. Having a vision is undoubtedly necessary.

B. Self-appreciation gets you to be positive to move you towards success.

C. Try to understand and let it be the guide to your life as follows.

D. Be sure that you are more powerful than you know.

E. Read and allow them to change your life in beautiful ways.

F. Sometimes we simply do what is expected of us without considering what we want to achieve.

G. You can make a bunch of excuses that you'll start when more experienced or richer.

Perhaps you have seen them, those who fall asleep on the subway and then, somehow, wake up exactly at their stop. Perhaps you are one of them. How is this possible? We spoke to two doctors, who offered their insights about it.

It is possible that your body gets used to waking up at a certain point each time during your commute, said Dr. Marc I. Leavey, a primary-care specialist in Maryland. That holds especially true if you commute at the same time every day. This suggests that if you were to get on at a different time, or if the journey were delayed, your internal clock might not wake you up at your stop. It is an interesting theory, but Dr. Ronald Chervin, director of Michigan Medicine's Sleep Disorders Centers, does not fully buy it. He is skeptical that circadian rhythms can also explain why you wake up after a brief nap.

You are also likely to wake up for your particular stop because of an oral cue, such as the conductor stating the name of the subway stop over the public-address system. Such cues alert your brain that you have arrived, explained Dr Leavey. According to a study published in the Public Library of Science, during sleep, our brain reacts differently when we hear our own name and other people's names, noted Dr Chervin. This suggests that your brain does not turn off during sleep, which makes it possible to pick up on the announcement of your stop.

Another reasonable possibility: You may wake up at each stop, check if it is yours, and go back to sleep, all without having remembered it, added Dr. Chervin. He sees this in cases where patients are suffering from sleep apnea. They may wake up as many as 200 times during a single night, without having remembered a single instance. That's because they fall right back asleep before their brain has time to process their experience into long-term memory. Similarly, you could be waking up every time you hear a new stop called. But you just don't remember such instances even after you fully come awake for your stop—leading you to believe that you have slept the whole way through and miraculously woken up at the right time.
