My Effort in Improving My English

Last Tuesday, February 26 2014 Mr.Marsigit give English Class to my class, Mathematics Education C about the method to improve English ability. Although I didn’t attend the class but i get the recording of the matter from my friend. Mr.Marsigit tell us that English is very important because English is life. English is used to communicate to other people in International Communication. So we have to improve our English. In my ways to improve my English I have some efforts, that is by articles, song, video/movie, chatting, vocabulary cards and application in my smartphone. I like to read articles from electronic newspaper, blog or website. Ussualy I read from Jakarta Post, New York Times or Wikipedia. From the articles I have read I found difficult vocabularies. Then I made a list of the difficult words in my book and then I look for the meaning of the words in my  Alfalink or Dictionary. This way give me big benefit, not only make me understand many vocabularies but also scientific / high level vocabularies.  It’s not enough to see the meaning from dictionary. It’s better for us to write them to make our memory do better to memorize them.  If you read the meaning only, you will forget them quickly. The second one to improve my English is by English Song. I listen the song, search the lyric and the meaning of the song. From this way i also learn listening and i know the pronouncation, we know how to speak English word well. And of course we get many vocabylaries. The third way is coming from video/movie. I also use movie to improve my English. Not far from the song, by watching movie we also understand the pronouncation and the conversation. Please don’t read the translatation first. Just hear the conversation and guess the meaning from the action. If you still not able to understand the meaning hear the conversation and guess the meaning from the action. If you still not able to understand the meaning you can see the translatation. Not only from movie but also from other video like video from You Tube. From You Tube you can see many English Video. The most i love is National Geographic. You see others according to your interest. By watching video/movie make you able to communicate well. This teach you to accept information and make you able to speak English well. The successfull in English not only calculate from the rich the vocabularies but also from your listening ability and speak English well is the most. English not only reading or writting but also listening and speak. We are forced to understand what people said and they understand what we said. The other effort to improve my English is by chatting with foreign people. I use Italki and Facebook. From Italki we can choose people with specific language. The example we look for people who speak English and want to learn Indonesian and also we can choose the country. In Italki we can chat and also make a note. Maybe you can write your experience or some text. Then the native will correct our text. So we can learn the gramatical well. I prefer like to use the note than make a chat in Italki.  It is different to Facebook, I ussualy use it for chat to foreign people. But in my chat we also discuss some topics. From Facebook I have got several friends from aboard but I got two good realtionship friends. They are from Iran and Pakistan. My friend from Iran learn Indonesian so we make a chat in Indonesian. I can’t learn English from him. But I learn English from my friend from Pakistan. He speak English well and we have many disscussion about many things. Then we make group in Facebook named “My Overseas Friends”. We invite our friends to join the group and make some disscuccion or a conversation. It’s not the whole of my efforts. I also have tried make vocabulary cards. I made some cards from color carton in 3 cm x 5 cm. I wrote 5-10 words in every cards with have same category. The example is I want to learn about Family. So I write down Father, Mother, Sister, etc. After that I write the meaning in the backside of the cards. Maybe some of you like this way. But I didn’t enjoy this way so I left it. I also use my smartphone in my effort. I download some application from the smartphone like dictionary and English Test application. There is many exercises of English Test with the answer key. So we can learn English well. And the newest way in improving my English is by reading English novel. I bought “The Land of Five Towers”,  English version of “Negeri 5 Menara” compiled by Ahmad Fuadi. I have read the Indonesian version 3 years ago and i want to try to read the English. But actually it is hard for me. I have read a little but I have gave up to continue to read this novel. Maybe in the future. That is all of my efforts in improving my English ability. I hope I can communicate well in English in the future.

Ancient Volcano Named Nglanggeran

On 1^st December 2013 I and my friends did a trip to Gunung Kidul, Yogyakarta. We Climbed an ancient volcano named Nglanggeran located in Patuk area. We set off from the hostel at 8:30 am and arrived 45 minutes later. We paid 5000 rupias every single person for the ticket, then we are ready to hike this ancient volcano. The trip to the summit top of Nglanggeran was very enjoyable. We passed the stairs of stone and earth. Indeed, there were many large boulders that were very beautiful. In fact, sometimes we had to pass through a very narrow route, passing between two narrow rock cliffs. In Nglanggeran there is also a camping ground. But as it happened, when we were there no one was camping.

Before reaching the top we want to turn first to Mata Air Comberan (Comberan spring). We climbed the wooden stairs to the large rock that was in front of us, after arrived on the high stone, I saw that the road was difficult for me. I did not dare go there because it passes through two narrow cliffs. Unlike the previous cliff where we walked on land between the two cliffs,  this time we were not walking on the soil, we have to stick to the cliff because under us is like a small and narrow gap. although it is not too narrow and steep, for me it was too extreme. Only two friends passed, me and my other friends followed the route back to the peak, the road to the top was more slippery than before. With the peak already in sight, we met a friend of our group  who had reached the summit long before us. We just reached the peak when he was  already going down. Then I told him about our friends who were in the Mata Air Comberan and they were going there too.

To get to the second rocky peak we had to climb the stairs, there was only one path. Because of many visitors going down, we has to queue up first. While we were sitting, suddenly two friends who went to Mata Air Comberan arrived through other routes. Indeed, there is more than one road to the summit, and more than one  summit, there are two peaks. We chose 2^nd peaks because the main top would require passing a long route. Once the queue was finished, we climbed the log stairs one by one. After reaching the peak, we lost all sense of fatigue. How beautiful the scenery we can see from the 2^nd top. From the second peak , we can also see the main top. At the top, the wind is blowing pretty hard, so it is not recommended to smoke cigarettes at the top because it will quickly run out.  From the top we can also see Embung, water storage reservoirs. How beautiful the scenery on top of Nglanggeran.
