这句英语哪里错了?She has come back here since 2010.

“She has come here an hour ago”这句话对吗? She can't come here because she has much work to do.（同意句转换） he has said he would come here ---这句是不是省略了“that”,请问什么时候“that she is __________(live)here ever since she has tea 问一道简单的英语题.She has worked here since last year.(对since last y she has lived here since ten years判断正误,错的改过来 Does she has a computer?这句话哪里错了? 英语填空 就2个空!She has gone to the park.She'll come back at about she has been back here for last weekend为什么表示她现在不在这 He has lived here since 1999(since1999为划线句) they will come back after comes here的同意句 “I hope you to come here tomorrow”这句话哪里错了,为什么?
