帮我看看这几个英语题对了吗?错了就帮我纠正一下吧,We're from China."China"有下划线.(对划线部分提问)我的答案是:Where are you from?Lingling is my good friend.(同义句)答:Lingling and I are good friends.I'm Chinese.(同义句)答:I'm from China.I'm in Class One with Daming and Lingling.(同义句)答:Daming,Lingling and I are in Class One.根据答语写问句.我写的是:What class are you in?We're in Class Five.我写的是:How is your mother?My mother is well.帮我看看这几个英语题对了吗?错了就帮我纠正一下吧,(大小写,be动词,复数单数都对了吗?)很感激您,
