表示“客观存在”时二者可以互换用。
Have you any money with you?=Is there any money with you?
老师,这句话是表示“客观存在”吗?
have和there be能否互换要看是表示“所属定义”还是表示“存在定义”,一般应该注意以下几种状况:
1. have表示“所属定义”;there be表示“存在定义”。比较:
Jack has a car. 杰克有一辆车。(所属定义)
There is a housefly on Jack. 杰克身上有只苍蝇。(存在定义)
2. 只有“所属定义”而无“存在定义”,要用have。比如:
The table has only three legs. 这张桌子只有三只脚。
There are only three legs on the table.
3. 只有“存在定义”而无“所属定义”,要用there be。比如:
There is a computer on the table. 桌上有一台电脑。
The table has a computer.
4. 既有“所属定义”也有“存在定义”,have和there be可互换用。比如:
A week has seven days. = There are seven days in a week.
Our school has about 3000 students. = There are about 3000 students in our school.
