A bear is a true symbol of the wildlife. A bear is a very large and powerful animal well known to anyone. They are usually quite furry and can be brown or white (polar bears); even a panda can be called a bear.
For a human meeting a bear can be extremely dangerous, but in normal life, they are very calm and quiet, looking for some food and raising their baby-bears. Nevertheless, a mother-bear often avoid leaving its child with a father-bear as it can be quite dangerous too.
Depending on a habitat, their diet can vary significantly, but in most cases it consists of fish, roots, berries and other food can be found in a forest (or in a snowy area if we are speaking about white bears).
It is very interesting that bears, even if they are grown up, prefer to stay close by to their parents as long as possible.
Bears eat a lot in the summer and autumn to gain weight (mainly fat) to survive in winter, when it is impossible to eat regularly.
Медведь – настоящий символ дикой природы. Это очень большое и сильное животное, знакомое каждому. У медведей густая шерсть; они могут быть коричневыми или белыми (полярный медведь). Даже панду можно назвать медведем.
Для человека встреча с медведем может быть крайне опасна, однако в обычной жизни они тихие и спокойные: ищут еду, воспитывают медвежат. Тем не менее, мамы-медведицы предпочитают не оставлять медвежат со своими отцами, так как это тоже небезопасно.
В зависимости от места обитания, рацион медведя различается, но в основном он состоит из рыбы, корней, ягод и других съедобных продуктов, которые можно отыскать в лесу (или в снегах, если говорить о полярных медведях).
Интересно, что даже взрослые медведи предпочитают оставаться как можно ближе к своим родителям на протяжении всей жизни.
Чтобы выжить зимой, когда невозможно регулярно находить пищу, летом и осенью медведи очень много едят и откладывают жир.
Telephone
People have invented many useful devices. One of the most interesting and widely-used inventions is the telephone. The modern phone that we use today is the result of work of many people. The first person to have patented the telephone in 1876 was Alexander Graham Bell. He is credited as the inventor of this practical device. Other scientists who also worked on telephone invention were Elisha Gray, Antonio Meucci, Thomas Edison and some others. The 20th century was the era of phone development and modernization. Rotary telephones were replaced by touch-tone dials and other sophisticated features. Modern phones are presented mostly by mobiles, which support IP telephony and wi-fi. It is almost impossible to find a person nowadays who doesn’t have a personal mobile phone. These phones have become highly popular over the last years. They are rather compact, handy and easy to carry around. Mobile phones allow us to make instant calls, send text messages, listen to music, play games, take photos, check an e-mail and else. Thus, they have replaced not only landlines but also personal computers, MP3-players and cameras. However, there are many people in the world who are against mobiles phones. Doctors claim that this device has a bad effect on people’s health. It can damage our eyesight and immune system. The signals that are sent from mobiles can be harmful. Some people also believe that phones prevent live communication. And, it is true. With the appearance of mobile phones and computers people meet up with friends less often. In my opinion, telephone is a very useful and important device. We simply can’t live without it in the modern world, even though it is not safe for health. The only solution is to try to use it less in everyday life.
