(疑问句和否定句中,some改为any, something改为anything.)5) There is something new in today’s newspaper.→Is there anything new in today’s newspaper?特殊疑问句:There be句型的特殊疑问句有以下三种形式 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?”。其中there在口语中常常省略。注意:无论原句的主语是单数还是复数,对其提问时一般都用be的单数形式(回答时却要根据实际情况来决定)。如: 6) There is a bird in the tree. →What’s in the tree? 7) There are some bikes over there. →What’s over there?8) There is a little girl in the room. →Who is in the room? ② 对地点状语提问:用 “Where is \ are + 主语?”表示(注意其答语变化):例如: 9) There is a computer in my office. → Where is the computer? ----It’s in my office. 10) There are four children in the classroom. →Where are the four children?--They’ re in the classroom. ③ 对数量提问:一般有两种提问方式: 如果主语是可数名词,无论是单数还是复数,都用“How many +可数名词复数 + are there + 介词短语?”表示:11) There are twelve months in a year. →How many months are there in a year?12) There is only one book in my bag. → How many books are there in your bag?13) There is a cat in the box. → How many cats are there in the box?如果主语是不可数名词,则用“ How much + 不可数名词 + is there + 介词短语?”表示:14) There is some money in my purse.→ How much money is there in your purse?三、用法:1.
