wǒ jiā fùjìn yǒu yí gè xiǎo gōngyuán.

In Mandarin, 我家 is the more natural way to say my home / my family’s place in everyday speech.

• 我家 literally looks like I + home, but it commonly means my home.
• 我的家 is grammatically possible, but it often sounds more explicit or emotional, like stressing my home in contrast to someone else’s.

So in a normal sentence like this, 我家附近 is much more natural than 我的家附近.

Because 附近 means nearby / आसपास / vicinity and it attaches to the place it refers to.

So:

• 我家附近 = the area near my home
• literally: my home + nearby area

This is a very common pattern in Mandarin:

• 学校附近 = near the school
• 公司附近 = near the company
• 地铁站附近 = near the subway station

So the order is:

place + 附近

not the English-style near + place.

Yes, you can. 在我家附近有一个小公园 is also correct.

Both are natural, but they feel slightly different in structure:

• 我家附近有一个小公园。
  The location 我家附近 is introduced first as the setting/topic.
• 在我家附近有一个小公园。
  This explicitly marks the location with 在.

In everyday speech, Mandarin often omits 在 when the location is used as the topic at the beginning of the sentence.

So both work, but 我家附近有一个小公园 is very smooth and common.

Because 有 means to have / there is / there are, and this sentence is expressing existence.

The pattern is:

place + 有 + thing

So:

• 我家附近有一个小公园 = There is a small park near my home

You would not use 是 here, because 是 links one noun to another, like A is B.

Compare:

• 这是公园。 = This is a park.
• 我家附近有一个公园。 = There is a park near my home.

So for saying that something exists somewhere, 有 is the right verb.

The structure is:

location + 有 + number/classifier + adjective + noun

In this sentence:

• 我家附近 = location
• 有 = there is
• 一 = one
• 个 = classifier
• 小 = small
• 公园 = park

So literally it is something like:

Near my home, there is one small park.

This location + 有 + thing pattern is extremely common in Mandarin.

Because Mandarin usually needs a classifier (also called a measure word) between a number and a noun.

The pattern is:

number + classifier + noun

So:

• 一个公园 = one park
• 三个学生 = three students
• 两本书 = two books

Here, 个 is the classifier. It is a very common general classifier.

For 公园, 个 is natural and standard:

• 一个小公园

Without the classifier, 一公园 would be ungrammatical.

This is because of a tone change rule for 一.

Normally, 一 is pronounced yī, but its tone changes depending on the tone of the following syllable.

Before a 4th tone syllable, 一 becomes yí.

Here:

• 个 is gè (4th tone)
• so 一 + 个 becomes yí ge / yí gè

That is why the pinyin is written yí here.

A quick summary:

• before 4th tone: 一 → yí
• before 1st, 2nd, or 3rd tone: 一 → yì
• when said alone or emphasized: yī

Because in Mandarin, adjectives usually come before the noun they describe, just like in English.

So:

• 小公园 = small park
• 大房子 = big house
• 新车 = new car

So this part is actually quite straightforward for an English speaker.

Usually it means a small park, but in real usage it can also suggest a little local park or a modest neighborhood park, depending on context.

So 小 can be:

• literally physical size: small
• or a softer, everyday descriptive word: little

In this sentence, it most likely just means a small park near the speaker’s home.

That would mean something different.

• 我家附近有一个小公园。
  = There is a small park near my home.
• 我家附近有一个公园，公园很小。
  = There is a park near my home, and the park is very small.

In 小公园, 小 directly modifies 公园 as part of the noun phrase.

In 公园很小, 小 is the predicate adjective and makes a full statement: the park is small.

So both are correct, but they do different jobs.

Mandarin does not have articles like English a / an / the.

Instead, Mandarin often uses context, numbers, classifiers, and word order.

Here:

• 一个小公园 naturally gives the sense of a small park

If the park were already known from context, Mandarin might simply say:

• 我家附近有个小公园
• or in another context just 那个公园 = that park

So Mandarin handles definiteness differently from English.

Yes, sometimes. You can also say:

• 我家附近有个小公园。

This is very common in spoken Mandarin.

一个 and 个 can both introduce something indefinite, a bit like a in English. In casual speech, 有个 is especially common.

So:

• 有一个小公园 = slightly fuller
• 有个小公园 = very natural in conversation

Both are correct.

In this sentence, it behaves like a location word / localizer.

That means it helps describe a spatial relationship:

• 我家附近 = near my home
• 学校旁边 = beside the school
• 桌子上面 = above the table

So it is not acting like an adverb here. It forms a location phrase with 我家.

A useful way to think about it is:

noun/place + location word

Examples:

• 我家附近
• 商店后面
• 楼下

Because 的 is often omitted in fixed, natural location expressions like this.

You may sometimes see 我家附近的... when 附近 is used to modify a following noun:

• 我家附近的公园 = the park near my home

But in your sentence, 我家附近 is a complete location phrase by itself:

• 我家附近有...

So 的 is not needed there.

With 有, the negative form is 没有, not 不有.

So:

• 我家附近没有小公园。
  = There is no small park near my home.

Or:

• 我家附近没有一个小公园。

But in natural speech, 没有小公园 is more common than 没有一个小公园 unless you want extra emphasis.

So the key rule is:

• 有 → 没有 for negation

A few useful points:

1. 我家 is usually said smoothly as a unit.

   • wǒjiā

2. 附近 is also a common two-syllable chunk.

   • fùjìn

3. 一 changes tone here:

   • yí ge

4. The sentence is often spoken in chunks like this:

   • 我家附近 / 有一个 / 小公园。

If you say it naturally, it will sound less like separate dictionary words and more like connected speech.

Not here. Although 有 can mean to have, it also means there is / there are when used to talk about existence in a place.

Compare:

• 我有一本书。 = I have a book.
• 桌子上有一本书。 = There is a book on the table.
• 我家附近有一个小公园。 = There is a small park near my home.

So the meaning of 有 depends on the structure:

• person/thing + 有 + object → possession
• place + 有 + object → existence

Here it is clearly the existence pattern.
