Like most tourists, I enjoy taking photographs on holiday and can't wait to show them to friends and family when I get back. But whilst for me they represent treasured memories, to others they are more often than not simply a collection of boring, badly composed, out of focus pictures. So this year I decided to do something about this by booking myself on a trip to Rome which included photography lessons.

The first time I went to Rome, I remember thinking that it was a photographer's paradise with a fantastic photo opportunity lying around every corner. (1)___ Added to this was the fact that there were crowds of tourists everywhere, blocking all the best views. But this second time things were different. Antonio, my photography tutor, was on hand to give expert advice every step of the way.

The first thing Antonio told our group was that the secret to creating a good photographic image rather than just a snapshot is to first take a long look at what you want to photograph. For example, he said, you should consider the background just as much as you do the subject. (2)___ You can get unwanted figures out of your image simply by getting down on your knees to take a picture, for instance, or changing the angle of the shot.

Our first port of call was Piazza Navona, where Antonio gave us advice about how to photograph the Fountain of Neptune. (3)___ Then, he added that we should take the photo with the fountain slightly off centre.

Next, we headed off to the Pantheon, which was originally an ancient Roman temple. Along the way, I took the opportunity to photograph anything that caught my eye. The Pantheon itself is so huge that it is impossible to take a good photograph of the whole thing. (4)___ I tried out this technique by lying down on the floor and taking a picture of just one section of the great domed ceiling. I was pretty pleased with the results.

For the next couple of hours, we wandered around the historic centre visiting many of Rome's architectural highlights. (5)___ And I felt that I was really able to appreciate the sights as I had to look at each one so carefully in order to get good pictures.

We finished off our first morning tour with a stop at a traditional Roman street café. After all the hard work and walking I'd done, a large Italian ice cream seemed like the perfect reward! (6)___ It felt like a whole new world had opened up to me. I learnt an incredible amount over the next two days, as well as having a thoroughly enjoyable time in one of the world's most beautiful cities.

§ 1. If you've ever thought that talking to someone was a waste of breath, you might be comforted to know that in some cases you are right  — the words we utter have very little effect on people compared with how we say them and what we are doing when we say them.

§ 2. Recent research has shown that in a presentation before a group of people, 55 per cent of the effect on the audience is determined by the body language of the speaker, 38 per cent by their tone of voice and only 7 per cent by the actual content of what is being said. Body language speaks louder than words.

§ 3. So can performance and communication skills really be improved? It would appear so, according to Neuro-Linguistic Programming, or NLP, which was developed in the 1970s by therapist Richard Bandler and linguistics professor John Grinder. They asked: "What makes the difference between someone who is competent at something and someone who is excellent?" They examined the behaviour of people generally considered to be examples of excellence in their respective fields to identify what they were doing consciously (осо­знан­но) and unconsciously. Surprisingly, they discovered patterns of communication which all these high achievers were using to produce consistently positive results. They found that they were able to copy these strategies and achieve similar success, so they developed a way of teaching these skills to other people, a method they called Neuro-Linguistic Programming.

§ 4. They have discovered how people achieve mutual understanding, both consciously and unconsciously, by observing the body language and voice patterns of the person they are talking to. If you're dealing with someone who is painfully shy, you're not going to make a good connection by overwhelming them with your cheerfulness. By matching someone's behaviour we can gain their confidence, achieve a good relationship and improve the quality of communication  — in other words, we can get on someone's wavelength. NLP practitioners claim anyone can learn how to do this, and quite quickly. NLP is all about taking one's unconscious, not very highly developed skills and practising them consciously.

§ 5. Another powerful aspect of NLP is its use of positive thinking. We can become aware of the negative and turn it to the positive. Once it is framed in a positive way as a goal, the brain can begin to cope with it and then apply itself to achieving that outcome. To put it another way, if you don't know where you're going, it makes it harder to get there.

These days the media is full (1) ... stories of celebrities’ private lives: their relationships, problems with weight and so on. In fact, (2) ... public seems to have (3) ... never-ending appetite for this type of gossip. It could be argued that celebrities invite publicity, for instance (4) ... giving interviews or welcoming the media into their homes. However, there are several reasons why celebrities deserve a certain level of privacy. Firstly, while some people actively seek (5) ... fame, others do not. Secondly, reporters are more interested in selling a sensational story than in investigating something (6) ... genuine importance. Lastly, the unwelcome attentions of reporters and photographers can put celebrities under great stress. Just think of Michael Jackson or Princess Diana. (7) ... balance, I believe that celebrities have the right (8) ... the same kind of privacy as anyone else.

Му life with CVD by Tony Wong

§ 1. I had just started middle school and we all had to do a series of tests. I was taken to a room where a mysterious woman handed me an odd-looking picture made up of dots. 'What number do you see?’ she asked with a smile. I didn’t know why she was smiling because there were a lot of dots to count. Once I got to about ten, she asked the same question. I didn’t know what to say, so she gave me another picture which looked the same as the first. I got upset. 'I don’t see any numbers,’ I said. That was how I learnt that I had CVD, colour vision deficiency, or, as it's unfairly known by the general public, colour blindness. What most people would have seen in that test was a number made of pink dots which they were expected to pick out from a circular field of green dots. I just saw lots of grey dots.

§ 2. I’m not alone. It is estimated that about eight percent of men have some form of CVD. It’s all down to genes, apparently, and scientists hope to cure it one day, although I can’t say that I would be keen on any gene therapy. Personally, I don’t feel like I ‘suffer’ from CVD.

§ 3. Generally speaking, people with CVD just adapt to the world around us. For example, when you get to the traffic lights, the key thing is not the colour but the order of the lights. Of course, with all the vandalism in my neighbourhood. I'm just happy if the traffic lights are working.

§ 4. Unfortunately, not everything is so clear cut. When my e-reader is recharging, the light is orange when it is charging and green when it is finished. That’s great, except that both colours look more or less the same to me. A much better system would be the one that my electric razor uses. It flashes when it is charging and then stops when it has finished.

§ 5. Life is full of little frustrations like that. Because I see green and red as pretty similar, I do sometimes put on a top that doesn’t go with my trousers.

§ 6. However, there are bigger problems that can occur when professionals don’t take CVD into account. I once failed an exam at school because a key question related to a bar chart coloured red, green and blue. To me all of the rectangles looked almost the same. Similar problems still crop up in course books and exams today.

§ 7. Moments like that aside, in my own life, CVD has been more of an inconvenience than a problem. People like me live life just like anyone else. We can continue to do so as long as people in positions of responsibility take steps to prevent any problems before they occur.
