Are you interested in studying abroad? Zealand to study English last summer. I went to New It was an amazing experience for me during those ten weeks. I believe that studying abroad is very meaningful for high school students. Now, please look at Slide 1. It shows the number of Japanese high school students studying abroad from 2009 to 2019. The number went down once in 2015, but in 2017, the largest number of students, more than 45,000, studied abroad. In 2019, the number went down a lot because of big international problems, but we believe that more students will study abroad in the future. So, where did many students go? Look at Slide 2. It shows the countries that the high school students in Minami City went to from 2009 to 2019. We can see that more than half of the students went to English-speaking countries This means that many students used English during their stays. I think that we can improve our language skills by communicating with local people a lot. For example, before studying at a English, but my English (Ave school in New Zealand, I wasn't very good at improv after staying there. But studying abroad isn't easy for everyone. Having friends from abroad is good, but not everyone has that chance. So, how should we study English in Japan? We asked 500 students at this high school, "How do you study English at home?" Look at Slide 3. It shows the results. Among these several ways, we recommend watching movies and TV dramas in English. We think so because by watching them, we can also learn about the people living there and their cultures. Learning these things is as important as learning the English language itself. We think that learning English is very useful for high school students. Study hard, and if you have a chance, please go abroad and learn many things.
