mary's being ill.为什么不能用mary..为什么一定要用mary's ..是不是因为后面是ing形式动词,所以人称代词要用所有格.. Mary's being chose中的Mary's是Mary has 还是Mary is 【英语分词与谓语动词】高手速来不清楚什么时候用分词,什么时候用谓语动词比如：____,Mary had to stay at home to look after herA,being ill B,to be ill C,her mother was ill D,her mother being ill为什么答案选D,不 My father`s being ill worried us `s being做什么 ill-being可不可数? Mary is being ill 后再加什么什么 这是不是作状语啊 分析下语法结构? ___,Mary had to stay at home to look after her.A.Her mother was ill B.Her mother being ill 注：要具体解析 his mother being ill,he had to stay at home 为什么用being? as the most excellent one in her university___as the most excellent student in her university,as most classmates had expected,made her parents very happy.A.Mary was chosen B.Mary's chosenC.Mary being chosen D.Mary's being chosen 请问ABC为什么错 释疑：Being ill,he didn’t go to school.我想问being在这里属于什么结构,表示什么?为什么用being呢?而不是having been ill 请教英语语法,Because of后面的being ill是什么语法,看不懂例法：He didn't go to school because of being ill yesterday.他昨天没去上学,因为生病了.例句后面Being ill 为什么要用Being he is afraid of being ill.being how can you being ill ______,I went to school instead of her yesterday.A.she is ill B.Her being ill C.She being illD.Being ill为什么不选A 要选B? ____,so he didn't come to school last week.A.Though he was ill B.being ill C.Having been ill D.He was 选哪个?为什么? Being ill,he didn't come.being这里是现在分词做状语,可以为什么要加上be呢,我直接把ill改成现在分词不行吗 关于“his mother being ill,he had to stay at home,looking after her”his mother being ill,he had to stay at home,looking after her这个句子中,为什么用being ill 不用was ill或者is being ill呢?还有,looking after her与主语是什么 Being ill,she stayed at home.为什么这个现在分词作状语是要用被动式?
