(Có, tôi muốn đến tham quan trạm vũ trụ vì tôi rất tò mò về môi trường bên ngoài Trái Đất.)
- No, I wouldn’t like to visit space station because it is so dangerous and I am afraid of height.
(Không, tôi không muốn đến tham quan trạm vũ trụ vì nó rất nguy hiểm và tôi sợ độ cao.)
Hi everyone, I'm at my uncle and aunt's house in Nha Trang. I went to my uncle and aunt's house 5 hours ago and now we are going around Nha Trang and see all in their. We are having an interesting sightseeing. My most favorite place in Nha Trang is beach. The beach is very beautiful. One more my favorite thing in Nha Trang is foods. We tried many delicious foods and I love bread the most. In addition, people in Nha Trang are very friendly. My uncle and aunt bought me a blue hat, it's so great. That's all of my visiting now. I will tell you more when I come home. Love everyone.
