Jenny is swimming in the swimming pool 对划线部分提问 swimming划线 The dog is swimming at the pool ,对at the pool提问 She is swimming at the pool改为一般疑问句 girl,in,who,the,pool,is,swimming连词成句 连词成句:girl,in,who,the,pool,is,swimming --------- Mike like swimming at the pool?是is 还是are Everybody is in the swimming pool改为否定句 what about------（swim）in the pool?look,she is swimming in the pool Les is swim in the pool.同意句 — — swimming in the pool?— —swim in the pool? There is also a 50-metre-long swimming pool 同义句=The swimming pool is ( ) ( ）（） there is a swimming pool near school 还是 there is a swimming pool near the school?我认为是后者 swimming (at)还是(in) the swimming pool look.the man with his friends ( )at the pool.括号里应填：is swimming或are swimming She is swimming（at the pool)对括号句子提问 ___ ___she swimming? jim with his friends ()in the pool now ,这里为什么填is swimming而不是are swimming
