Photographs are everywhere. They decorate the walls of homes and are used in stores for sales of different goods. The news is filled with pictures of fires, floods, and special events. Photos record the beauties of nature. _ can also bring things close that are far away. Through photos, people can see wild animals, cities in foreign lands, and even the stars in outer space. Photos also tell stories. Reporting the news through photos is called photojournalism. At times photojournalists tell their stories through a single picture. At other times, they use a group of pictures to tell a story. Each picture is like a chapter in a book, which can do more than record the facts. It can also be a strong force for social change. Jacob Riis was among the first photojournalists. He took pictures of parts of New York City where the poor lived. Riis believed that poverty caused crime, and he used photos to help him prove his point. A few years later, the photos of small children working in factories by Lewis Hine shocked the public. Hine's pictures helped bring about laws to protect such children. Hundreds of pictures may have to be taken in order to get one or two really good photos. It takes science to have the photo come out clearly and art to make a photo that has a good design and expresses feeling. Photojournalists make an actual record of what they see. A photo, however, can be both a work of art and an actual record. It can record an important event as a beautiful or exciting picture. As historical and artistic documents,photos can become more important over time. Today photojournalists still have their pictures appear in newspapers and magazines. They also publish them in books and on the Internet. The photos of the small children by Hine show us that photos _ . A) are also works of art B) are popular ways of reporting news C) often shock the public D) can serve as a force for social change

Q: The famous American gorilla expert Diane Fossey had a completely new way to study gorillas -- she pretended to be one of them. She copied their actions and way of life -- eating plants and getting down on her hands and knees to walk the way a gorilla does. It was a new relationship. Diane Fossey was murdered in Rwanda in 1985 and her story was made into the popular filmGorillas in the Mist. It was a long way fromKing Kong, which is about a gorilla as a monster (a frightening animal), and helped to show a new idea: the real monster is man, while the gorilla is to be admired. Today there are thought to be around 48,000 lowland gorillas and maybe 400--450 mountain gorillas in the wild. From the Congo in West Africa, to Rwanda and Uganda further east, they are endangered by hunting and by the cutting down of their forest homes. Some time ago, I found in my letterbox a little magazine from the World Wide Fund for Nature. It had two photos side by side. One was of a young gorilla. "This is a species of mammal ," said the words below it. "It is being destroyed by man. We must save it for our own good." The other photo showed a human baby. The words also read, "This is a species of mammal," but then went on: "It is the most destructive on earth. We must retrain it for its own good." The text mainly talks about _ . A) Diane Fossey B) the gorillas in Rwanda C) the protection of the gorillas D) the film Gorillas in the Mist

Clean your ears, because airport security might soon be scanning them. According to a recent discovery, the shape of ears could provide a reliable new way of identifying people at airports. Researchers discovered that ears of each person have a unique shape and they have created a system that can scan them. The ear scanning technique uses a technology called image ray transform that highlights all the tubular structures of the ear and measures them. Professor Mark Nixon, a computer scientist who led the team from the University of Southampton, believes ear scanning could take place as passengers walk through security gates, for example, by placing cameras on either side to record an image of their ears. Comparing the results against a database of ear shapes, the new system could help airport security workers instantly identify passengers. Nixon and his team tested 252 images of different ears and found the system was able to match each ear to a separate image held in its database with 99 percent accuracy. Besides ear scanning, there have been other systems developed for identity recognition. "With facial recognition, the systems are often confused by crows feet and other signs of ageing," Nixon said. "Your ears, however, age very gracefully. They grow proportionally and your lobe gets a bit larger, but otherwise your ears are fully formed from birth." What's more, facial recognition software is often confused by changes in expression so people need to control their faces and in some cases even avoid wearing make-up. An ear scan system would also offer a less _ alternative toretina scanning, which requires passengers to stare at scanners from a close range. Fingertip detection has long been the most effective way of identifying someone. Nixon expects there to be a combination of different techniques that can be used at the same time to identify a person." Ear scanning would work better than facial recognition mainly because _ . A) the ear scanning system is computerized B) ears change less with age than faces C) facial expressions are often the same D) facial appearances aren't unique
