The invention of the camera goes far into the past. In the 1500s, men were experimenting with cameras that made images. But it was not until the early 1800s that man found a way to make the pictures permanent. Even then, photography was a new field. Most families had their pictures taken by a photographer. People did not own cameras because taking pictures and developing the film were too difficult. In 1884, George Eastman changed photography by inventing a kind of film that fit into a small camera. Because the new film was easy to use, many people began to buy cameras. When they had used up their film, people returned their cameras to the factory. There, the film was developed, and pictures were printed. Then more film was put into the cameras, which was sent back to the owners, along with their pictures. Eastman's camera made it easy to take pictures. Today's cameras are even easier to use, and people can put in their own film. Photography has become a growing hobby. There are also many new jobs in the field of photography. One of the most important kinds of work is in news reporting. Newspapers, magazines, and television all need pictures to tell their stories. Photographers aid scientists by taking pictures through microscopes and telescopes. Deep-sea divers take pictures of ocean plants and animals, while astronauts take cameras into space. Man finds new uses for the cameras every day. In 1884, George Eastman changed photography by inventing a new kind of _ . A) image B) factory C) film D) camera

Our children and grandchildren may not have a chance to visit many of the most famous places around the world. War, weather, age, traffic and pollution damage these famous places. Looking after these places often costs more than one country can afford. In the early 1970s, world governments decided that if they joined together, they would be able to preserve our history. If every country paid some money, they said, it would be possible to look after important historic places. Also, if they discovered that a monument needed urgent help, they would have money for repairs. For these reasons, countries around the world united to form the World Heritage Organization in 1972. Today, the organization helps to maintain and restore the most important places from our history. However, one of the biggest problems for historic places is vandalism. People sometimes enter the sites and destroy or damage the buildings. At some sites, such as Stonehenge in England, governments have built high fences to protect the site from vandals. There are many different ideas about how to solve the problem of vandalism. Some experts say that if guards patrolled the sites, vandals would not be able to get in. Some experts say that if they fixed more television cameras, they would not need so many guards. Other experts say that the best solution is education. If people learned to respect history, they would not destroy or damage it. They would also want to spend money looking after old places. For this reason, the World Heritage Organization helps to spread information about the value of historic sites. Which of the following shows us the action of vandalism? A) People enter the sites and destroy or damage the buildings. B) Governments build high fences to protect the site from vandals. C) Guards patrolled the sites and they fixed more television cameras. D) They also spend money looking after old places.

Q: Living and dealing with kids can be a difficult job these days, but living and dealing with parents can be even more complex. If I have learned anything in my 16 years, it is that communication is very important. With any relationship, you need to let other people know how you are feeling. If you are not able to communicate, you drift apart . When you are mad at your parents, or anyone else, not talking to them doesn't solve anything. Communication begins with the concerns of others. It means that you can't just come home from school, go up to your room and ignore everyone. To keep a good relationship, you must keep communication, even if it's just by writing a note. When dealing with parents, you always have to make them feel good about how they are doing as a parent. If you are trying to make them see something as you see it, tell them that you'll listen to what they have to say, but ask them politely to listen to you. Yelling or walking away only makes the situation worse. This is an example: one night, Sophie went to a street party with her friends. She knew she had to be home by midnight after the fireworks, but she didn't. She was late getting home. Her parents were mad at first, not giving Sophie a chance to explain why she was late. Later, they kept calm and listened to her. Communication is the key factor here. If Sophie's parents had not been willing to listen, Sophie would have been in a lot of trouble. Which is the key to a happy relationship? A) Children should always obey their parents. B) They should be equal. C) Parents play the leading part. D) Both make the opposite know their anger.

Scratchy throats, stuffy noses and body aches all spell misery, but being able to tell if the cause is a cold or flu may make a difference in how long the misery lasts. The American Lung Association (ALA) has issued new guidelines on combating colds and the flu , and one of the keys is being able to quickly tell the two apart. That's because the prescription drugs available for the flu need to be taken soon after the illness sets in. As for colds, the sooner a person starts taking over-the-counter remedy, the sooner relief will come. The common cold and the flu are both caused by viruses. More than 200 viruses can cause cold symptoms, while the flu is caused by three viruses - flu A, B and C. There is no cure for either illness , but the flu can be prevented by the flu vaccine, which is, for most people, the best way to fight the flu, according to the ALA. But if the flu does strike, quick action can help. Although the flu and common cold have many similarities , there are some obvious signs to look for. Cold symptoms such as stuffy nose, runny nose and scratchy throat typically develop gradually, and adults and teens often do not get a fever. On the other hand, fever is one of the characteristic features of the flu for all ages. And in general, flu symptoms including fever and chills, sore throat and body aches come on suddenly and are more severe than cold symptoms. The ALA notes that it may be particularly difficult to tell when infants and preschool age children have the flu. It advises parents to call the doctor if their small children have flu-like symptoms. Both cold and flu symptoms can be eased with over-the-counter medications as well. However, children and teens with a cold or flu should not take aspirin for pain relief because of the risk of Reye syndrome ,a rare but serious condition of the liver and central nervous system. There is, of course, no vaccine for the common cold. But frequent hand washing and avoiding close contact with people who have colds can reduce the likelihood of catching one. If children have flu-like symptoms, their parents _ . A) are advised not to give them aspirin B) should watch out for signs of Reye syndrome C) are encouraged to take them to hospital for vaccination D) should prevent them from mixing with people running a fever
