Sports can help you keep fit and get in touch with nature. However, whether you are on the mountains, in the waves, or on the grassland, you should be aware that your sport of choice might have great influence on the environment.

    Some sports are resource-hungry. Golf, as you may know, eats up not only large areas of countryside, but also tons of water. Besides, all sorts of chemicals and huge amounts of energy are used to keep its courses(球场) in good condition. This causes major environmental effects. For example, in the dry regions of Portugal and Spain, golf is often held responsible for serious water shortage in some local areas.

    There are many environment-friendly sports. Power walking is one of them that you could take up today. You don't need any special equipment except a good pair of shoes; and you don't have to worry about resources and your purse. Simple and free, power walking can also keep you fit. If you walk regularly, it will be good for your heart and bones. Experts say that 20 minutes of power walking daily can make you feel less anxious, sleep well and have better weight control.

    Whatever sport you take up, you can make it greener by using environment-friendly equipment and buying products made from recycled materials. But the final goal should be "green gyms". They are better replacements(代替物) for traditional health clubs and modern sports centers. Members of green gyms play sports outdoors, in the countryside or other open spaces. There is no special requirement for you to start your membership. And best of all, it's free.

    Culture shock is the psychological（心理的）shock of having to adapt to new environment and new cultures which may be completely different from your own. To understand culture shock helps to understand what culture is.

    Culture shock is caused by the feelings that result from losing all familiar signs and symbols of social intercourse（交往）. Those signs include the ways with which we are familiar in daily life: When to shake hands and what to say when we meet people? When and how to give tips? How to go shopping? When to accept and when to refuse invitations? These signs, which may be words, gestures, facial expressions, customs or normals are gained by all of us in the course of growing up and are as much a part of our culture as the language we speak.

    During the first few weeks when a person enters a strange culture, most people are attracted by the new. But this “cooks tour” type of mentality（心态）does not normally last if the foreign visitor remain abroad and has to seriously deal with real conditions of life. He may feel anxious and frustrated（受挫的） People react to the frustration in the same way. During the first period, they reject the environment which causes the discomfort. “The ways of the host country are bad because they make us feel bad,” they complain about the host country and its people. The following period is homesickness. The home environment suddenly becomes so important that all difficulties and problems are forgotten and only the good things back home are remembered.

    Experiencing culture shock can be very difficult. There is a risk of sickness or emotional problems. However, culture shock can be part of a positive learning experience. Be patient! It is a process of adaptation to new situations. If you do like this, you will be a much stronger person, and you will be a citizen of the world.

    FOR ALL the technological wonders of modern medicine, from gene-editing to fetal(胎儿的) surgery, health care—with its fax machines and clipboards(资料夹)—is often stubbornly old-fashioned. This outdated era is slowly drawing to a close as, slowly, the industry catches up with the artificial-intelligence (AI) revolution. And it should have happened earlier, argues Eric Topol, a heart doctor keen on digital medicine.

    Dr Topol's vision of medicine's future is optimistic. He thinks AI will be particularly useful for repetitive tasks where errors arise easily, such as selecting images, examining heart traces for abnormal symptoms or recording doctors' words into patient records. In short, AI is set to save time, lives and money.

    Much of this is imaginary—but AI is already defeating people in a variety of narrow jobs for which it has been trained. Eventually it may be able to diagnose and treat a wider range of diseases. Even then, Dr Topol thinks, humans would watch over the rules, rather than being replaced by them.

    The author's fear is that AI will be used to deepen the assembly-line(流水线) culture of modern medicine. If it awards a "gift of time" on doctors, he argues that this additional benefit should be used to extend the time of consultations, rather than simply speeding through them more efficiently.

    The Hippocratic Oath holds that there is an art to medicine as well as a science, and that "warmth, sympathy and understanding may be more important than the surgeon's knife or the chemist's drug". That is not just a cliché: the patients of sympathetic physicians have been shown to do better. As Dr Topol says, it is hard to imagine that a robot could really replace a human doctor. Yet as demand for health care goes beyond the supply of human carers, the future may involve consultations on smartphones and measurements monitored by chat robots. The considerately warmed stethoscope(听诊器), placed gently on a patient's back, may become history.

    Still seeking a destination for your weekend break? There are some places which are probably a mere walk away from your college.

    King's Art Centre

    A day at the Centre could mean a visit to an exhibition of the work of one of the most interesting contemporary artists on show anywhere. This weekend tees the opening of an exhibition of four local artists.

    You could attend a class teaching you how to 'learn from the masters' or get more creative with paint—free of charge.

    The Centre also runs two life drawing classes for which there is a small fee.

    The Botanic Garden

    The Garden has over 8, 000 plant species; it holds the research and teaching collection of living plants for Cambridge University.

    The multi-branchedTorch Aloe here is impressive. The African plant produces red flowers above blue-green leaves, and is not one to miss.

    Get to the display house to seeDionaea muscipula, a plant more commonly known as the Venus Flytrap that feeds on insects and other small animals.

    The Garden is also a place for wildlife-enthusiasts. Look for grass snakes in the lake. A snake called 'Hissing Sid' is regularly seen lying in the heat of the warm sun.

    Byron's Pool

    Many stories surround Lord Byron's time as a student of Cambridge University, Arriving in 1805, he wrote a letter complaining that it was a place of "mess and drunkenness". However, it seems as though Byron did manage to pass the time pleasantly enough. I'm not just talking about the pet bear he kept in his roans. He spent a great deal of time walking in the village.

    It is also said that on occasion Byron swam naked by moonlight in the lake, which is now known as Byron's Pool. A couple of miles past Grantchester in the south Cambridgeshire countryside, the pool is surrounded by beautiful circular paths around the fields. The cries of invisible birds make the trip a lovely experience and on the way home you can drop into the village for afternoon tea. If you don't trust me, then perhaps you'll take it from Virginia Woolf—over a century after Byron, she reportedly took a trip to swim in the same pool.
