My favorite month is May, because there are many events   in this month. May 1 is Labor Day . We have a three-day holiday  . We can have a trip. We have an Art Festival on May 8 in our school. We like it very much,we like to show our pictures. May 12 is my good friend Linda's birthday. We have a big birthday party for her . On May 20 , we have an English party. We often have in the evening. We have a book sale in our classroom on May 28 . It's very interesting. Students show their pictures    _    .
