Look,here is/are my hat and my key?is or are?

Look,here is/are my hat and my key?is or are? 为什么在Look,here is my hat and my key.种中要用is而不是are呢? Look!Here ___________ my father and mother.A.am B.are C.is D.be Look!Here _____some photos of my new school.A.is B.Are C.am D.be Here is my cakes 还是 Here are my cakes 是here are my mother and my father还是here are还是here is Look at the m什么.MY bouse is here. 请问为什么这里的is为什么不能换成are 或者am.或者do呢?句子是：look.here is my hat and my key. look,here（ ）is. can i look at this red coat.yes------填here are you here is it here you are 根据句意、所给首字母写出单词 ——Your phone is d_______from my phone.Can I have a look?——Sure.Here you are. Tom and Mike ------here 填be动词怎么填 是is还是are ,好像here填动词要看离be动词最近的一个词或词组,是单数就is,是复数就are.如果是or 就是就近原则,就要填is了.那样的话为什么Look,here is my hatand my k This is my book,Here you are!如何回答 Ah,this is my rubber.Here are you.找错,一个 Hope I'm making you 回答是：you sure are.Just look at my buddy here. what are you doing here?i______(look)for my new coat 为什么Here is my umbrella and my coat用is 反过来就用are?为什么Here is my umbrella and my coat用is 反过来 My umbrella and my coat are here 用 are? Where‘s my keys?A.Here they're B.Here it is C.Here you are D.They're here
