Q: Article: We are much happier in our new house because it has a large garden, and you know how enthusiastic we both are about gardening. When we moved in a month ago, Mary wanted to get a dog to keep out burglars. However, we finally decided that it would be cheaper to put an iron grille in front of the door and get a burglar alarm. Last week, I went to a shop and bought an alarm for just over PS200. It consists of a control unit with three smaller units. I put the control unit in the lounge and put the other units in place by the front door, back door and lounge windows. That night I soon fell asleep because I was confident that no one could get into our house undetected. At about 1:50 a.m. I woke up suddenly and heard the siren. It was like an ambulance driving right through our bedroom. I couldn't leave the siren on all night. I went downstairs in the dark. When I reached the bottom of the stairs, I switched on the light and looked around. Oh my gosh. The back door was unlocked. I rushed to lock it and it was just at that exact moment that the 'burglar' disappeared behind a curtain. Guess what? It was an ordinary house lizard .Apparently the alarm system had been made for American or European homes in which lizards are never seen. I switched the alarm off and sat down to watch. A few moments later, a lizard ran across a wall, right in front of one of the alarm units. I won't bother to finish this story but if you'd like a burglar alarm system free of charge, just let us know.

Q: Article: I was dirty smelly hungry and some somewhere beneath all that, suntanned .It was the end of an Inter-Rail holiday.My body couldn't take any more punishment. My mind couldn't deal with any more foreign timetables, currencies or languages. " _ ," I said, as I stepped onto home ground.I said exactly the same thing the following year.And the next, all I had to do was buy one train ticket and, because I was under twenty--five years old,I could spend a whole month going anywhere I wanted in Europe. Ordinary beds are never the same once you've learnt to sleep, in the passage of a train, the rhythm rocking you into a deep sleep. Carrying all your possessions on your back in a tucksack makes you have a vefy basic approach to travel,and encourages incredible wastefulness that can lead to burning socks that have become too anti-social ,and getting rid of books when finished.On the other hand, _ is entirely in the spirit of Inter--Rail,for common sense and reasoning can be thrown out of the window along with the paperback book and the socks.All it takes to achieve this carefree attitude is one of those tickets in your hand. Any system that enables young people to travef through countries at a rate of more than one a day must be pretty social on that first trip,my friehds mad I were at first unaware of the possibilities of this type of train ticket,thinking it was just an inexpensive way of getting to and from our chosen camp-site in southern France.But the idea of non-stop travel proved too attractive,for there was always just one more country over the border,always that little bit further to go.And what did the extra miles cost us? Nothing. We were not completely uninterested in culture.But this was a first holiday without parents,as it was for most other Inter-Railers,and in organizing our own timetable we left out everything except the most available sights.This was the chance to escape the guided tour,an opportunity to do something different.I took great pride in the fact that.in many places,all I could be bothered to see was the view from the station.We were just there to get by,and to have good time doing so.In this we were not different from most of the other Inter-Raiders with whom we shared passage floors,food and water,money and music. The excitement of travel comes from the sudden reality of somewhere that was previously just a name.It is as if the city in which you arrive never actually existed until the train pulls in at the station and you are able to see it with your own tired eyes for the first time.

Q: Article: Many people say dolphins are very intelligent. They seem to be able think, understand, and learn things quickly. But they are smart like humans or more like cats or dogs? Dolphins use their brains differently from people. But scientists say dolphin intelligence and human intelligence are alike in some ways. How? FACT 1: Talk to Me Like humans, every dolphin has its own "name". The name is a special whistle . Each dolphin chooses a specific whistle for itself, usually by its first birthday. Actually, scientists think dolphins, like people, "talk" to each other about a lot of things, such as their age, their feelings, or finding food. And, like humans dolphins use a system of sounds and body language to communicate. But understanding their conversations is not easy for humans. No one "speaks dolphin" yet, but some scientists are trying to learn. FACT 2: Let's Play Dolphins are also social animals. They live in groups called pods, and they often join others from different pods to play games and have fun ---just like people. In fact, playing together is something only intelligent animals do. FACT 3: Fishermen's Helpers Dolphins and humans are similar in another way: both make plans to get something they want. In the sea of southern Brazil, for example, dolphins use a interesting strategy to get food. When fish are near a boat, dolphins signal to the fishermen to put their nets in the water. Using this method, the men can catch a lot of fish. What is the advantage for the dolphins? Why do they assist the men? The dolphins get to eat some of the fish.
