I have been a special education teacher for 17 years and I wish more people would get into special education.The position is very demanding and there is always a shortage of special education teachers.It is not an easy profession to get into. One needs a BA in education and then a special education certificate such as a certificate in learning disabilities, emotional disabilities or cross categories which means covering all the subjects.A certified new special educate teacher needs to _ a current special education teacher for at least, a year because there is that much to know and practice. Working with the students is the biggest reward.However, the paperwork is huge with requesting more year after year.If you are good at doing about ten things at the same time, then you may be the right person for the job. No day is the same. Parent and government expectations are high. A sense of empathy(the ability of feeling and sharing another person's feelings) and one hundred percent prepared to help your students is important. Also, if you are a special education teacher working in the high school, it is your job to make sure your special education students are able to be employed after they graduate, and then the special education teacher needs to stay in touch with the special students a year after they graduate to make sure they are employed and can support themselves. Education is a very political field next to working in politics. One needs to know what to say, when to say it and make sure it is a benefit for everyone involved. It is a mixture of knowing medical diagnosis and teaching with that in mind. Your record needs to be perfect, and it would also help to be a very strong Christian because you will need to pray often to yourself. This position is not about the money but more of a service. Which of the statement is NOT true about the author _ . A) He is a certified special education teacher B) He enjoys working with disabled teenagers C) He used to do large amounts of paperwork D) He tries to encourage people to become special teachers

Ques: Robert Altman's films were different from the usual methods of Hollywood movie storytelling. In the 1940s, he started his film career directing industrial movies in his hometown of Kansas City, Missouri. Later, he moved to Hollywood, California, to make television shows. His first major film, MASH, was released in 1970. It tells about a group of American medical workers in an army hospital in Korea during the Korean War in the 1950s. The movie was a great success. It questioned the rules of the military in a way that was sharply funny and clever. Robert Altman continued to make movies with strong political and social points. His next major movie, Nashville, came out in 1975. This movie provides a complex (not simple) look at changes in the country music industry. Robert Altman's movies have a very special style. Often, his actors speak so naturally that it is hard to believe they are performing. Altman liked his actors to be free to make up their own lines. Altman wanted to copy the way people talked and acted in real life. And he was willing to fight with movie studio businessmen to make sure that he had total creative control over his work. Even as an old man, Robert Altman continued to make movies. Many of his 33 films were nominated for Academy Awards, including The Player and Gosford Park.

Ques:When I first heard about geocaching ,I was skeptical. But the more I thought about it, the more it seemed like an interesting idea.I at least wanted to try it once. Having familiarized myself with how the game works,I set out in search of my first cache. My trip took me through a series of lively hutong ,past a number of small temples, and right into the courtyard of a quiet youth hotel.I spent several minutes looking around, but couldn't find anything. Just before l was about to give up,I spotted a colorful object in the crack of a wall. Could it be the hidden cache? At that moment a group of backpackers amved. According to the game's rules, people who are not in the game must not be allowed to find out about secret caches. So I pretended to make a phone call while waiting for them to leave. When the coast was clear,I grabbed the object. It was the cache! I opened it and pulled out a crumpled sheet of paper with several names and celebratory messages written on it.I added my own and replaced the cache in its hiding place, ready for the next geocacher to find. It may seem like a simple game, but the idea that there are caches hidden all around us is exciting. Once you're hooked, it's easy to set yourself the goal of finding every single cache in a neighborhood or even an entire city. The real treasure, however, is not the cache itself, but the places it takes you to. Hunting for further caches has since introduced me to places which I didn't even know existed. Some are peaceful parks, while others are forgotten historical sites.A few caches have even been in places I passed regularly without giving them any thought. Now,Ifeel a much closer connection. When a group of backpackers were approaching, the author _ . A) pretended to be cleaning the yard B) made a call to other geocachers C) didn't allow them to come in D) tried to keep the cache secret
