For more than twenty years scientists have been searching for signs of life on other planets. Most of these searches have been done over the radio. The hope is that someone in outer space may be trying to get in touch with us. Scientists also have sent radio and television messages on spaceships traveling through space, on the chance that someone may be receptive （善于接受的） to such messages.

    Scientists are using powerful radio telescope to listen to signals from about 1,000 stars, all within 100 light years of earth. In addition, they will scan (扫视) the entire sky to “listen” for radio messages from more distant stars. Using a computer, they will be able to monitor more than eight channels at one time. Scientists are looking for any signal that stands out from the background noise.

    Of the 200 billion stars in the Milky Way galaxy （银河星系）, scientists find that five percent are like our sun. Perhaps half of them have a planet like earth. Such a planet would be a reasonable distance from the star for temperatures to be right for the evolution of life. Based on the inhabitable (that can be lived in) planets in our galaxy, most scientists agree that chances are likely that one or more of these planets support some life.

    However, many scientists wonder whether intelligent （有智力的） life exists on other planets. Some believe that twenty years of searching without any intelligible （可理解的） messages shows that no one is out there. They say that the evolution of intelligence comparable to ours is unlikely.

    Other scientists believe that our search hasn't been long enough to rule out the possibility that intelligent life exists in our galaxy. Although our sun family in only about five billion years old,  our galaxy is about 20 billions years old. In that time, some scientists think it is likely that civilizations are much more advanced than ours. Perhaps these civilizations send us no signals; perhaps we have not recognized the signals they have sent us. If we hope to find intelligent life, these scientists believe that we have to keep looking.

    Can dogs and cats get along well in the same home? People who are thinking about getting a dog as a friend for their cat are worried that they will fight. A recent research has found that if the cat is taken back home before the dog, and if they are introduced when still young (less than 6 months for cats, a year for dogs), it is highly probable that the two pets will get along swimmingly. In two-thirds of the homes cats and dogs have a good relationship.

    However, it wasn't all sweetness and light. There was a reported coldness between the cat and dog in 25% of the homes, while aggression(侵略，好斗) and fighting were found in 10% of the homes. One reason for this is probably that some of their body languages are just different. For example, when a cat turns its head away it means aggression, while a dog doing the same means submission(顺从).

    In homes with cats and dogs living peacefully, researchers found a surprising behavior. They are learning how to talk each other's language. It is a surprise that cats can learn how to talk "Dog", and dogs can learn how to talk "Cat".

    What's interesting is that both cats and dogs have appeared to become smarter. They can learn to read each other's body languages, suggesting that the two may have more in common than was expected. Once familiar with each other's body language, cats and dogs can play together, and enjoy sleeping together on the sofa.

    The importance of this research on cats and dogs may go beyond pets — to people who don't get along well, including neighbors, colleagues at work, and even countries. If cats and dogs can learn to get along, surely people have a good chance.

    Some people might dream of splendid surroundings—but also need a reasonably affordable cost of living. Try one of these four astonishing spots for a magical retirement, from an International living.com report, where retirees can live well on less.

    Sintra, Portugal

    A favorite summer retreat of former royalty, which is just a 40-minute train ride from Lisbon, is the pastel-painted Palace of Pena, a 19th-century Romanticist marvel with pink turrets and daffodil-yellow tower on a hill surrounded by pine forests. A couple could live well in this arts-rich tourist town, though pricier than other cities in Portugal, on a budget of $ 3,065 a month.

    Cusco, Peru

    Cusco, Peru's most historic city, is a UNESCO World Heritage site. Once an Incan capital. Cusco has clear, sunny days. Colonial structures have been changed into fashionable restaurants, shops and even homes. Superfoods, like chia seeds, quinoa and maca, are inexpensive and plentiful. A retired couple could enjoy a good life on$ 1,700 a month.

    The West Coast, Ireland

    The Wild Atlantic Way is a cycling or driving route that stretches across the west coast of Ireland. At the heart of the route is one of the most amazing natural wonders, the landmark Cliffs of Moher in County Clare—one of Ireland's most visited natural attractions. On a budget of around $ 2, 800 a month, a retired couple could live quite comfortably.

    San Miguel de Allende, Mexico

    San Miguel was declared a UNESCO World Heritage City in 2008.The colonial centro has much to offer retirees: low cost of living, arts, charming local cultural traditions and mild weather year-round. San Miguel is a few hours' drive from Mexico City. The days are comfortably warm and the nights blessedly cool. A retired couple could live comfortably on a monthly budget of $ l, 650.

At the beginning of the century there was a big farm called Hollywood Ranch. It was near Los Angeles in California. A few years later Hollywood was one of the famous places in the world. From the 1910s to the 1950s Hollywood was the film center of the world. Every family knew the names of its film stars — Charlie Chaplin, Grela Garbo, Bergman and hundreds more.

The reason why people went to Hollywood to make films was the sun. At first people made films in New York on the east coast of the United States. But then they heard about Los Angeles where there are 350 days of sun every year. As they made all the films by sunlight, the west coast was a much better place to work. Also near Hollywood you can find mountains and sea and desert. They did not have to travel far to make any kind of film.

When TV became popular, Hollywood started making films for television. Then in the 1970s they discovered people still went to the cinema to see big expensive films. After twenty years they are still making films in Hollywood and people watch them all over the world.
