The weather is a national obsession in Britain, perhaps because it is so changeable. It's the national talking point, and most people watch at least one daily weather forecast. Most of the viewers imagine that the presenter does little more than arrive at the studio a few minutes before the broadcast, read the weather, and then go home.

In fact, this image is far from the truth. The two-minute bulletin which we all rely on when we need to know tomorrow's weather is the result of a hard day's work by the presenter, who is actually a highly-qualified meteorologist.

Every morning, after a weather forecaster arrives at the TV studios, his/her first task of the day is to collect the latest data from the National Meteorological Office. The information is very detailed and includes predictions, satellite and radar pictures, as well as more technical data. After gathering all the relevant material from this office, the forecaster has to translate the scientific terminology and maps into images and words which viewers can easily understand. The final broadcast is then carefully planned. The presenter decides what to say and in what order to say it. Next a “story board” is drawn up which lays out the script word for word.

The time allocated for each broadcast can also alter. This is because the weather report is screened after the news, which can vary in length. The weather forecaster doesn't always know how much time is available, which means that he/she has to be thoroughly prepared so that the material can be adapted to the time available.

What makes weather forecasting more complicated is that it has to be a live broadcast and cannot be prerecorded. Live shows are very nerve-racking for the presenter because almost anything can go wrong. Perhaps the most worrying aspect for every weather forecaster is getting the following day's predictions wrong. Unfortunately for them, this is not an unusual occurrence; the weather is not always possible to predict accurately.

These days, a weather forecaster's job is even more complicated because they are relied upon to predict other environmental conditions. For example, in the summer the weather forecast has to include the pollen count for hay fever sufferers. Some also include reports on ultraviolet radiation intensity to help people avoid sunburn. The job of a weather forecaster is certainly far more sophisticated than just pointing at a map and describing weather conditions. It's a job for professionals who can cope with stressful and challenging conditions.

The passage is mainly about _________.

A. weather forecast in England

B. a weather forecaster’s job

C. the most widely watched TV programme

D. the competition between weather forecast and other TV programmes

Read the following passage and mark the letter A, B, C, or D on your answer sheet to indicate the correct answer to each of the questions from 28 to 34.

When we meet people for the first time, we often make decisions about them based entirely on how they look. And of course, we too are being judged on our appearance. Undoubtedly, it’s what’s inside that’s important but sometimes we can send out the wrong signals and so get a negative reaction, simply by wearing inappropriate clothing.

When selecting your clothes each day, it is therefore important to think about who you’re likely to meet, where you are going to be spending most of your time and what tasks you are likely to perform. Clearly, on a practical level, some outfits will be more appropriate to different sorts of activity and this will dictate your choice to an extent. However, there’s no need to abandon your individual taste completely. After all, if you dress to please somebody else’s idea of what looks good, you may end up feeling uncomfortable and not quite yourself.

Some colours bring your natural colouring to life and others can give you a washed-out appearance. Try out new ones by all means, but remember that dressing in bright colours when you really like subtle neutral tones or vice versa will make you feel self-conscious and uncomfortable. You know deep down where your own taste boundaries lie. It may be fun to cross these sometimes, but do take care not to go too far all at once.

Reappraising your image isn’t selfish because everyone who comes into contact with you will benefit. You’ll look better and you’ll feel a better person all round. And if in doubt, you only need to read Professor Albert Mehrabian’s book Silent Messages, which showed that the impact we make on each other depends 55 percent on how we look and behave, 38 percent on how we speak, and only seven percent on what we actually say.
