单词
语法
There be的否定句构成和含有be动词的其它句型一样,在be后面加“not”。语法公式:There be+no/not a+名词Example:There is a calender on the desk. 桌子上有一个日历。—There isn't(is not )calender on the desk. 桌子上没有日历。—There is no calender on the desk. 桌子上没有日历。
There be结构的一般疑问句变化只要把be动词移到句首,再在句尾加上问号即可。Example:There are some books in her schoolbag. 她书包里有一些书。—are there any book in her schoolbag? 她书包里有书吗?
对主语提问。当主语是人时,用“Who's+介词短语?”Example:There is a cat in the kitchen. →what's in the kitchen?当主语是物时,用“What's+介词短语?”Example:There is a little girl in the room.→who is in the room?(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)。
对数量提问。当主语是可数名词,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?”Example:There are twelve months in a year.—How many months are there in a year?There is only one book in my bag.—How many books are there in your bag?当主语是不可数名词,则用“How much+不可数名词+is there+介词短语?”Example:There is some money in my purse.—How much money is there in your purse?
There be表示“存在有”,通常是物做主语,而have/has表示“拥有、所有”,通常是人做主语,两者不能同时使用。Example:There are three books on the desk.I have three books.
there be句中be动词的使用要和其后的主语在人称和数量上保持一致。
如果主语是单数的可数名词,或是不可数名词,be动词用“is”“was”。
如果主语是复数名词,be动词用“are”“were”。
如果有两个或两个以上的名词作主语,be动词要和最靠近它的那个主语在数上保持一致(就近原则)。
Example:There is an orange and some bananas in the basket.
