It is all because of that 为
Basically the following two sentences have the same meaning:
English translation will be:
We provided this chair specifically for the elders
It is actually quite common to use the 为 to move the verb after the subject to emphasize the "for"
My heart only beats for you
This is the classic "topic-comment" structure in Chinese sentences. Bring the object of the verb to the beginning of the sentence for focus and emphasis, then comment on it.
Homework (topic) - he didn't do one bit (comment).
He didn't do one bit of homework.
French (topic) - I don't know how to say even one sentence (comment).
It is acceptable and understandable. 作業他一點都沒做。(He did not even do small amount of homework.)
Think the component as [thing][person][description used to denote less amount of thing][description used to emphasize not][action], where [person] is the one that did not even perform the [action] on small amount of [thing]. [description used to denote less amount ...
就 has many meanings, In different context, '就是' could mean 'is exactly' ; 'then it is' ; 'just/ only'
他最怕的话题[就是]关于爱情的话题 = The topic he afraid the most, [is exactly] the topic about love
讨论完关于工作的话题, 接下来[就是]关于爱情的话题 = Finished discussing the topic about job, next [then it is] the topic about love
他什么书都看，[就是]关于爱情的他不看 = He read any kind of book, [just/...
This is not natural for me, because 一个 is not necessary. It is more natural to say 商店里也没有面包. 也 means "the same as x" here. "x" here can be anything in the context. For example, we are taking a vlog now and do not have bread at home. Then we go to the store but there is no bread either. here home is the "x": the situation at store is the same as ...
我[可以]看一个月吗? = [Can] I read for one month? (O)
我看一个月[可以吗?] = I read for one month, [is it possible?] (O)
我[可以]看一个月. = I [can] read for a month. (O)
我看一个月[可以]. = I read for a month [can]. (X)
我看一个月? [可以]. = I read for a month? [(yes) It is possible]. (O)
"我看一个月可以吗" is a [topic] + [comment] sentence.
[我看一个月] is the topic
[可以吗?] is the comment
Your sentence is grammatically correct and it is a very common grammar structure
[如果 X 就 Y] = [If X then Y]
[1: 如果] [X: 没时间的话] [2:就] [Y:告诉我]
[1: if ] [X: suppose you have no time] [2: then ] [Y: tell me]
Notice 1: The subject 'you' is omitted in Chinese sentence and it is a very common practice, you can drop the subject as long as it is ...
I doubt if
我看一个月可以吗? , should be translated to
Can I read it for a month?
我看一个月可以吗? has other translation in advanced conversation
because verb and object is hidden
note: 看 can be translated to "do you think"
It can be interpreted as
Do you think/ Is it possible that
it can be done in a month?
But then I think you ...
就是 bascially means Yes/it is or Just/only or "Just yes"(exactly)
就是关于爱情的 means Just about love
(or Only about love, meaning not more than love)
Informally, you can treat 就是 as Yas. It can be used as exclamation.
就是 could of course be used on its own in everyday conversations as an exclamatory comment, like, when someone says, 呆在家里以防止冠状病毒covid-19传播是非常无聊的, and your comment, 就是！！！
呆在家里 = staying home
以防止 = to prevent
冠状病毒 = (Guānzhuàng bìngdú) = Coronavirus
Covid-19传播 = Covid-19 spread
是非常无聊的 = (shì fēi cháng wú liáo de) is very boring.
就是！！！ = exactly!!!
就是 denote some situation or things is true, you can think the component this way 就是[other description], where [other description] is description which is true. In your example, 就是关于爱情的(就是[other description], where [other description] is 关于爱情的) ((something) is about (other thing) of love). 关于爱情的 is true. It is used to show that something is about other thing ...

There are two kinds of usage of 给。Let's use the three sentences A, B and C as example:
In the sentence C, 给 means "passive", 门给风吹开了 = 门被风吹开了。
For the two sentences A and B, 给 is used to highlight some emotion a little. If you remove the 给 in the two sentences, they are still correct but they will become the same thing ...
