Chủ đề: Party.
Today, I am 16 years old, so I hold a birthday party at my house. The party began at 7h p.m and finished at 9h30 p.m on October 15th. I invited a lot of close friends ad intimate friends take part in the party. There is a two layer birthday cake with fifteen candles on the table. After people sang “Happy Birthday” song, I blew out the candles and cut the cake. Everybody ate cake, went to KTV and played mini games together. Finally, my friends returned their home, although they all tired, they felt so happy. Regarding me, I cleaned and washed up the party, then I went to sleep.
Chủ đề: Weather.
Vietnam is a tropical country. The climate is often hot and humid. In North Vietnam there are four seasons: spring, summer, autumn and winter. It is hot in summer and it is very cold in winter. In South Vietnam there are only two seasons: the rainy season and the dry season. It rains a lot from May to November. In the dry season it is very hot. Sometimes there are storms in the North and floods in the South.
I love spring. Because the weather at that time is very nice. it’s breezy and mild. The landscapes are very beautiful. I love going out in spring to see sky. Sometimes, I take photographs and they’re so nice.
