He is at home的句子结构主语：he谓语（系动词）：isat home是表语还是状语?

He is at home的句子结构主语：he谓语（系动词）：isat home是表语还是状语? 分析英语句子成分是不是最重要的是分析出句子的结构吖 好像 He is at home home是at的宾语 但不是句子的宾语 问一个英语句型的结构.请麻烦看看 ,He is good at playing basketball.在这个句子里如何分析结构?（He 做主语,is good at做谓语,playing basketball做宾语.是这样吗 ）He不是主语吗？is 系动词good at playing bask His children were at home last 句子的主语是什么? He is at home now,maybe.这个句子中at home now是状语吗 Maybe he is at home=He may be at home=?→He may stay home这个句子会错吗?我把home当成一个副词 Mrs.Smith is at home.史密斯太太在家.(介词短语at home作主语补语.)Mrs.Smith is 不是完整句子,为什么 at home.是主语补语呢,宾语不适完整句子了? 1主语补语指在带宾语补足语的结构变成被动语态后,原来的宾补,如：　　a.He was made to study hard what he was not good at.to study hard what he was not good at就是主语he的主语补语.那么对We arrive home sound and 英语句子结构分析 he is fond of taking a walk fond 起什么作用呢? 可不可以he是主语,is谓语,后面的表fond 起什么作用呢？ 可不可以he是主语，is谓语，后面的表语 英语句子结构分析 he is fond of taking a walkfond 起什么作用呢？可不可以he是主语，is谓语，后面的表语 将 Is Ann's mother at home 改为Could you please tell me 为主语的句子如何改?加if 或者that 这个是动词短语还是介词短语?be good at 这种类型的短语是动词短语还是介词短语?在句子中作什么成分?比如he is good at playing ball.这句话应该是系表结构,主语是he,系动词是is,后面是表语.介词短 he is at home 的同一句不对 He is at home.at home在句中做什么成分? where is your father?Is he at home No.he isn't.where is your father?Is he at homeNo.he isn't..He'll leave work and go home at five in the afternoon.填什么句子 he is good【】home 填at对吗? He is very helpful at home maybe he is at home=he may be at home.有没有其他类似的题目
