Is it a book ? yes,it's。 在回答中是不能用缩写的 应该为 Yes,it is. Is this yuor an eraser ? 去掉“an” what her famliy name? 正解为 what‘s (what is )her famliy name? 就这了 谢谢采纳
is it a book? yes,it is. is this yuor an eraser? 改成:it this your eraser? .yuor 的单词是错的,应为your. 句子中的an也要去掉! what her famliy name? 改成: what does her family name? 第三人称时用does,family改为family.
