Ive been studying at an American high school for about nine months. Unfortunately, I'm going to go back to Japan next month. But I've had a lot of fun, and I've learned alot during my time here. One of the things I learned is that I shouldn't be afiraid of making mistakes when I speak English. When I first arrived in the US, I was really nervous. I was worried about my English, so I didnt speak much. I felt really lonely. But one day, I went to a school party. I met some international students there. When I talked to them, I noticed that they were making a lot of mistakes in Englisn, but they didn't care. They told me that it was more important to communicate than to try to speak perfect English. Since then, I started to talk to my classmates more. After I started speaking more, I quickly made a lot of new friends. I still make mistakes when I speak English, but I've stopped worrying. Another thingIlearned here is that there are lots of things I don't know about Japan. Many people I've met here are interested in Japan. For example, in my first week of school, my classmates asked me lots of questions about Japan and its culture and history. Sadly, I couldn't answer some of the questions. When I looked for the answers, I discovered that Japanese culture and history were quite interesting. I've been learning about Japanese culture and history since then. I feel sad because I have to leave soon, but I'll never forget mv time in the US. I've learned so much here, and I hope to study here again.

分子が2つ以上の原子が結びついた粒子のことを言うのは分かるのですが、「分子のまとまりがない」というのが理解できないです…良ければ教えてください🙇‍♀️🙇‍♀️
