[연관] 주어 동사 찾아주세요 ! 1. With the growth of the Internet, tourism, and the global economy, it feels like the world is getting smaller. Ideas, products, and customs are flying from country to country. As the number of cultural exports grows, the world is truly becoming a global village. However, some people are unhappy about the rapid spread of foreign cultures. They worry it will harm their local identity. 2. Criminals are finding it harder to hide from the law. Trained with the latest technology, forensic scientists work with police departments. Using microscopes and computers, they help solve even the most difficult cases. Scientific techniques have been used in police work for centuries. In 1248, a book from China listed ways to figure out what weapon was used in a crime. Later, in 1775, a Swedish scientist learned how to tell if poison was used to murder someone. Then, in 1835, police officers in England started using ballistics. It’s a technique to match a bullet with the gun it was fired from. 3. In recent years, we’ve seen a new group of super givers. At the top of the list is Bill Gates. In 1994, using money from his Microsoft fortune, he set up the William & Melinda Gates Foundation. The foundation first helped US libraries get connected to the Internet. Then, it turned to fighting diseases like AIDS and malaria in poor countries. From 1994 to 2007, the foundation gave away more than $13 billion. 4. Many countries are going through an important population shift. People are having fewer children, and lifespans are getting longer. Living longer is great, but it leads to some problems. After people retire, they collect pensions, and their healthcare costs go up. Much of the burden for paying these costs falls on the current workforce. Yet, as the workforce gets smaller -- due to low fertility rates -- less tax money is collected. The situation puts heavy pressure on companies and governments. 5. New York City is made up of five sections, or “boroughs”:Manhattan, Brooklyn, Queens, the Bronx, and Staten Island. Although the city is spread out, its eight-million-plus residents can easily get around on the excellent subway system. Each year, more than 1.5 billion riders travel on one of twenty-six routes. 6. The world’s forests are disappearing. For a number of reasons, that’s cause for alarm. Governments, NGOs and private individuals are taking steps to reverse this trend. In many places, efforts are underway to restore forests that have been damaged or destroyed. The first step is to identify the species of trees that are native to the area. Ideally, a variety of species are planted. That improves an area’s biodiversity. Over the next two years, seedlings are monitored to make sure they grow healthily. 7. In many places around the world, people already live in crisis. More than one billion people have no access to clean water. That leads to millions of deaths every year, including thousands of children dying everyday in Africa. By 2025, as many as twenty-five African countries may face water shortages. It could even lead to wars over water rights. 9. Yoga has a long list of benefits. It improves strength, raises energy levels, and makes a person more flexible. On top of that, yoga can help with problems like back pain. And, it can help people lose weight. What’s more, yoga can lower one’s stress level and lead to a greater sense of calm. With all these benefits, it’s no wonder there are yoga classes in so many countries. Some new styles have even been developed outside of India. 10. Some countries, unfortunately, have had less success with reforestation. Illegal harvesting and livestock over-grazing are among the problems which they face. Despite such setbacks, reforestation efforts are spreading. More countries are becoming aware of the benefits brought by healthy forests. They improve the soil, stop the spread of deserts, and protect the ground water. Forests also help in the fight against global warming by removing carbon gases from the air. Furthermore, healthy forests make the land more beautiful for future generations.

[연관] Since a reinforcer must serve to strengthen the desired response, it is imperative that the counselor select a reinforcer that will have precisely this effect on the subject. For instance , the counselor wants John and Ellen to do certain tasks. To encourage each one, John is offered a ticket to a football game and Ellen is offered a ticket to the ballet as a reward for performing the tasks. This may be good if John likes football and if Ellen likes ballet, but it just so happens that John is an enthusiastic ballet aficionado and Ellen is a paasionate football fan. We see that inappropriate reinforcers were chosen for each of them, and that, therefore, the likelihood of either performing the task is greatly diminished. On the other hand, it is important that the correct reinforcer be selected for any individual - the reinforcer that will be most appropriate for him or her. 이 지문 해석 해주시고 문법적인거 있는 곳 찝어주세요.
