1．
European television had the idea of taking ordinary people and turning them into “stars” by putting them in unusual situations. “Big Brother” (created in Holland) was one of the first. A group of people were locked in a small house with cameras running 24 hours a day. It was called a “watch and dial” show because viewers vote by telephone to decide who should leave or stay.
2．
“Big Brother” was probably the first of the new reality shows, bus such a programme has developed. Many have found appeal by having a theme to them, but most are based on the principle of “survival of the fittest” by eliminating participants as the series progresses. So we have the dating shows where winners either pair off or stay true to their partners outside the TV studio. Then there are those that test people’s abilities for specific jobs like running a kitchen, becoming an interior designer or a top model.
3．
Critics say these programmes are basically bad television, but people watch them. So why are there so many of them? For the viewer it’s an opportunity to “people watch”. It’s natural to like watching other people. They’re interesting. We can imagine what we would do in that situation. We get to know the characters and see them grow and develop week after week. And of course, television is the perfect place to watch people. Like the theatre or cinema we can look at other people and they can’t look back. But with television, we can watch in the privacy of our own homes. We watch, but we don’t have to admit it to anyone.
4．
The TV companies like reality shows because they are cheap to produce and attract younger viewers, which advertisers like. The last “Big Brother” in Britain attracted enormous advertising revenue. They aren’t dependent on “star” actors with enormous salaries. And your actors won’t go on strike. And why do people participate in them? Well, for fame and money of course. In the past, appearing on television wasn’t for ordinary people. You had to be good at something, like sport, or reading the news, or acting. But not any more.
5．
It seems that most shows do well at the beginning but then the viewing figures begin to fall. And it varies from country to country too. For example, one show had an adopted child try to guess the identity of her real father, and another had a family arguing over an inheritance. Both were cancelled after one episode. Perhaps the novelty has worn off. Certainly, reality TV seems to appeal much more to the younger audience. And now there are so many shows around even the young have become more critical. Reality shows will probably survive – it’s just no longer so easy to make a successful one.

Directions: Read the following text and choose the most suitable heading from A-F for each paragraph．There is one extra heading which you do not need.
| A．Causes of overusing fluoride | B．Negative effects of fluoride |
| C．Safe use of fluoride | D．The expert’s background information |
| E．No need to worry about fluoride poisoning | |
| F．Solutions to improper use of fluoride | |
I have heard that fluoride can help stop dental decay, but I recently read that it is poisonous．Which of these is true? How can children use fluoride safely?
This question is answered by Dr Marcia M．Rich who practises general dentistry in Newholt．She is also a lecturer at the University and a writer for the monthly magazine Your Dentist Cares．
My answer to the first question is to stress that fluoride works well and is safe when users follow instructions．Young children have a tendency to swallow toothpaste, which is why they should only have a tiny amount of fluoride toothpaste on their toothbrush．If this simple measure is taken, parents can be confident that children will be protected against tooth decay, and come to no harm.
Almost all medicines have an adverse effect－or even be deadly－if they are not taken as directed．So you are right－fluoride can be poisonous if it is swallowed in very large quantities．It is for the reason that fluoride supplements can only be obtained on prescription from the doctor or dentist．Please be assured that fluoride overdoses are rare－in fact, I have never heard of any fatal incidents related to fluoride poisoning.
Scientific studies have shown that fluoride can help to prevent cavities as long as it is used correctly．If fluoride is abused, there is a risk of illness or even deaths in extreme cases．If a deadly amount of fluoride is taken, immediate first-aid could save a life．A person who has swallowed a large amount of fluoride will probably start vomiting．If not, the patient should be given milk or antacid and taken to the nearest hospital for emergency treatment.
Taking too much fluoride while teeth are growing can lead to a condition called dental fluorosis．The most likely cause is the swallowing of fluoride toothpastes by young children．It can also be caused by inappropriate use of fluoride drop or other fluoride supplements, for example when fluoride is already is already present in drinking water．
