题目

are the postman cold or hot ? 为什么回答是 they are not cold,they are hot 时隔多年,还是有些不懂
are the postman cold or hot ? 为什么他的回答是 they are not cold,they are hot 之前问过,还是有点不懂
are the the postman cold or hot ? 回答 they are not cold,they are hot.是因为are the postman 中的are吗?如果是 is the postman cold or hot ?那么回答就是 he is not cold,he's hot 对吗?
are the shops shut or open? 回答 : they are not shut,they are open...
问题可以写成 are these shops shut or open? 吗?
are the policemen short or tall? 回答: thy are not short,they are tall
问题可以写成 are they/these/them policemen short or tall? 三种吗...
问题低级, 英语好的人不要笑我...

答案

因为问题中是are,复数,postman是集体名词,可以代表一个同性质的群体.
当然如果问题中是is,回答是is,但这里情况不同.
可以用these取代the在没有特别指示时.
Are these 是可以的,但不能说are they/them policemen,但可以说are they short or tall, them 是宾语,不可放在主语位置,例postman deliever letters to me, I collect them.
