my birthday is May 1st的近义句是什么? _______________________________?My birthday is on May 1st. My birthday is on May 1st.My birthday is May 1st.哪一句才对? My birthday is Jun.2nd.（用May.1st来改为选择疑问句） 在英语里几月几号用介词on,那为什么My birthday is May 1st.不用呢 my birthday is on May 1st 中得 on 必须要用吗? MY birthday is January 1st my birthday is in may 的问句 My birthday is ( )May 21st. A.on B.in C.at my birthday is ( )( )May 21st.括号里应该填什么? 改句：My birthday is October 1st. 改错：My birthday is in 1st January
