Thank you very much.it's_____ of you.A kindest B a most kind

空格前应该还有个the~选C 乍一看B(精神上的富有)和C都可以~但为了和后面happiness对应所以选C~
volunteers believe that 是主谓语~后面一整句巨子是宾语从句~从句中the happiest people in the world 主语~are 谓语~those宾语 who help to bring happiness 做those的定语从句~
就是“志愿者们相信世界上一些最幸福的人是那些给别人带来幸福的人”

this is a kindest boy who helped me a lot with my English

of course you should choose A.因为此为定语从句,先行词为MAN有最高级修饰只能用THAT来引导
正解哦,百分百正确

很高兴为你
D
这里的most 是“很,非常”的意思
这句没有比较意味,不能选A,C; 不是名词词组,当然也不能选B

最高级前面一定要用the当定于从句的先行词（本句中即 teacher ）被形容词最高级修饰时,其后面的引导词（本句中即that）必须用that.什么情况下引导词一定要用that(1) 先行词是形容词最高级或者它的前面有形容词最高级时
This is the best that has been used against air pollution(反对空气污染) in cities.
English is the most difficult subject that you will learn during these years.
(2) 先行词是序数词,或它的前面有一个序数词时
He is the last person that I want to see.
(3) 主句中已有疑问词时以who或which引导的特殊疑问句,为避免重复,只能用that.例如：
Who is the girl that is crying?正在哭泣的那个女孩是谁?
Which is the bike that you lost?
(4) 先行词既有人又有物时
The bike and its rider that had run over (撞倒了)an old man were taken to the police station.
(5) 先行词是all,many,much,any,little,something,everything,anything,nothing,none,the one等代词时
You should hand in all that you have.
We haven’t got much that we can offer you.
I mean the one that you talked about just now.
(6) 先行词前面有only,any,few,little,no,all,one of,the same,the very,the last等词修饰时
The only thing that we can do is to give you some money.
Li Ming is the only one that got full marks (满分)in our class.
Li Ming is one of the students that want to be teachers in our class.
(7) 有两个定语从句,其中一个关系代词已用which,另外一个宜用that
Edison built up a factory(办了一个工厂) which produced things that had never been seen before.

你难道没发现,和蔼可亲的人会越来越美丽.

对我来说,最好的朋友不会是像你那样的朋友.生日快乐!

其实很简单.不是固定用法.
之所以你觉得有疑问是因为你把most看成是最高级了.
但别忘了most不仅仅可以作many/much的最高级,还可以作形容词,意思是：非常
相当于very
