She has been to us.里面是填a great help 还是a lot of help呢不填的那个请说明理由,

She has been very helpful to us.这属于什么时态,先谢啦 she has been to beijing (twice)提问 She has been to Xi'an b( ). Neither of us has been to Beijing.为什么用has she has Cuba for a long time 空里是不是添has been和has gone都行修改：been in和gone to都行 I want to know hoe long(she hai been back)括号里为什么不用 has she come back Not only has she been to America,but also she has been to Japan中为什么用has she she has been to Japan,hasn't she Your service request has been sent to us. many of us has been to shanghai什么意思 Where has she been? 为什么是Where has she been?而不是Where has she been to?；为什么She has been to Beijing.需要to大哥大姐,两问请都打 my father hasn't been to Britain.He has been to the US合成一句话 she has many things to tell us[改同义句】 She has been to us.里面是填a great help 还是a lot of help呢不填的那个请说明理由, She has been to shanghai already变成否定和疑问句 She has been to water world.（改为否定句） has she ever been to shanghai?做否定回答
