YesterdayLast night someone asked me a question: "What do you think about the interference posed by government on the right of abortion?

I am the third kid in my family, which is rare in China due to the One-Child Policy posedin place from 1978 to 2016.

You could also say third child, but "third kid" is also correct.

Should mothers get pregnant again after having one kid, there are two wayoptions left.

One is abortion, and the other is risking your life giving birth.

Even if the kid hasd already been born into this world, he or she couldn't get an ID card w. Without which you can imagine how inconvenient your life would br life would become quite inconvenient, as you could imagine.

I don't mean to complain about this policy, which indeed managed to control the explosive increase ofin population.

But it did deprive mothers' of their right of abortion.

The right of abortion shall contains two parts : If you want to get an abortion, you get it.

I and mMy second elder sister and I didn't have an ID card until 7 years after coming into this worwe were 7 years old.

I believe you are saying that you and your sister were not able to get an ID card until you turned 7.

My parents paid a large sum of fine in exchange for it.

You may want to change "it" to "the ID card" or "an ID card," but your sentence still makes sense.

I hope this world will never again see cruel interference on mothers' right on abortion.

Yesterday night someone asked me a question: "What do you think about the interference posed by the government on the right of abortion?

It's "asked" -- use the past tense here, because you are telling us about something that happened "yesterday night".

It's more common to say "the government" as it is an organization.

Let me introduce the story told to me by my mother.

The story was told "to me" (to yourself), after which you tell the story to us, the readers. It's a small, optional change, but it can make more clear how the story is being passed on.

One couple could only give birth tohave one kid.

"Give birth" is incorrect here because the couple doesn't give birth -- only the mother does. When referring to a couple with children, it's more common to say "to have kids/children".

Once captured by administration staffs, mothers would get thbe forced to get an abortion.

Staff is singular; it refers to many "employees", making up a team of "staff". Similarly, the second part of the sentence sounds odd. The meaning is understandable, but the structure could be improved.

Abortion is referred to as singular (an abortion).

The "mothers would be forced to get" is more impactful as it shows the lack of choice which you discuss in the story. Your original wording, "mothers would get" suggests the mothers have a choice (obviously, you then say "forced abortion" which negates that) but to simplify the meaning, it would be easier to phrase it as I did.

Even the kid has already been born into this world, he or she couldn't get an ID card -- without which you can imagine how inconvenient your life would be.

Using the "--" (dash) there breaks up the flow of the sentence. Think about where you would pause when speaking -- that's the place to use a dash, especially when you don't want to use another comma (,) in the sentence.

I and mMy second elder sister and I didn't have ID cards until 7 years after coming into this worwe were 7 years old.

The grammatically correct way to say this is "my second elder sister and I".

"ID cards" is plural, because you and your sister both received a card.

Also, it might be clearer to say "until we were 7 years old", because it has the same meaning as what you wrote but is easier to understand.

My parents paid a large sum of money -- a fine -- in exchange for it.

This is only a stylistic suggestion, because your sentence makes sense. This is a good place to use the "--" (dash) to break up the sentence and clarify what the money was, exactly.

I hope this world will never see cruel interference on mothers' rights on abortion.

"rights" would be plural here, because there are many laws etc. that make up the "rights" in this context.
