this year I had my Children's Day with my parents. They brought me to the central park to see the special childern's show and then bought me a toy cat as present. I ask my dad to buy me a big toy and some cotton candy as well. I enjoyed a lot at this year's Childern's Day.今年我和父母度過了兒童節(jié)。他們帶我去中央公園看那里的兒童節(jié)特別秀，然后還給我買了一只玩具貓做禮物。我要叫爸爸給我買一個大玩具還有棉花糖。我非常愉快地度過了今年的兒童節(jié)。給你找了一篇范文，希望對你有幫助吧
4 1=5套
所以?買5套等于便宜1套
所以?120元
新華書店為慶祝六一兒童節(jié)，買4套書送一套，每套120元，買5套比原價便宜120元
解：120×5-120×4=600-480=120元
