The dog has two big eyes. 当have表示“包括”、“存在”的含义时,There be 句型与其可互换。 eg. A week has seven days. =There are seven days in a week. 肯定句:There is a computer in your study. 否定句-在“be”后加“not”: There isn’t a computer in your study. 一般疑问句-将“be”提到“there”之前: Is there a computer in your study? -Yes, there is./ No, there isn’t. 特殊疑问句:There be句型的特殊疑问句形式有以下三种变化: ① 对主语提问:当主语是人时,用"Who's+介词短语?"; 当主语是物时,用"What's + 介词短语?"。 注:无论原句的主语是单数还是复数,对之提问时一般都用is(回答时却要根据实际情况来决定)。如: There are many things over there. →What's over there? There is a little girl in the room. →Who is in the room? ② 对地点状语提问:提问地点用"Where is / are+主语?" “There + be+主语+地点状语”表示“某处有某物”; 例: There is a computer on the desk. → Where is the computer?
