here is 50 dollars,有错吗,为什么不是here are?

here is 50 dollars,有错吗,为什么不是here are? Here () two dollars. be动词用are还是is? 为什么是是Here is two hundred dollars? 15 dollars are here, Here is a hundred of dollars.这里为什么要用is啊? 50 dollars前为什么加It is ,here are 15 dollars=?15 dollars are here Two dollars for one,here. Here (be) your 8 dollars. here is 15 dollars.let's go to KFC for lunch. 英语翻译具体语境如下:I want these runners.How much are they?These are seventy dollars and those are thirty dollars.Seventy dollars is too much!Will you take forty dollars?Li Ming!You can't bargain here! Here are 15 dollars.是什么意思?谢谢 Here (be动词) your 8 dollars. here you are和here it is和here is it有什么相同点和不同点? There is three dollars 还是There are three dollars The red sweater is 18 dollars对 18 dollars提问 these are so expensive.Ten dollars is ten dollars!Ten dollars is ten dollars怎么翻译比较好? 50 dollars后面用are还是is?钱后面应该是单数吧,但这里dollar后面有s,是不是应该用are?
