We always have many wonderful memories in our life。Now,I want to share my happiness with you。That was a sunny day,several of my friends and I went to Beihai Park。There are so many beautiful flowers and many tall green trees。In trere,we fed on lovely gold fish。Of course,there are many ducks and white gooses,we played with them by boat。Then,we had a picnic on the gress ground。In addition,we took a lot of photos。Finally,we saw sun-set all together。What an unforgettable day!
