kono tenzi ni ha, aburae to tyoukoku ga arimasu.

には is に + は.

• に marks the location or context where something exists.
• は makes この展示に the topic: as for/in this exhibition...

So この展示には、油絵と彫刻があります has a feeling like:

• In this exhibition, there are oil paintings and sculptures.
• As for this exhibition, it has oil paintings and sculptures.

Using は often adds a slight contrastive or topical nuance, even if that contrast is very mild.

Because は and が are doing different jobs.

• この展示には = the topic / setting
• 油絵と彫刻が = the things that exist in that setting

With あります, the thing that exists is usually marked by が.

So the structure is basically:

• [Place / context + に(は)] [thing] が あります

Example pattern:

• 部屋には机があります。
  • In the room, there is a desk.

Here:

• この展示には = in this exhibition
• 油絵と彫刻が = oil paintings and sculptures
• あります = exist / are

あります is the polite non-past form of ある, which is used for the existence of non-living things.

Since 油絵 and 彫刻 are objects, あります is correct.

Compare:

• 本があります。 = There is a book.
• 猫がいます。 = There is a cat.

So:

• non-living things → ある / あります
• living things (people, animals) → いる / います

と is the particle used to mean and when listing items completely.

So:

• 油絵と彫刻 = oil paintings and sculptures

This sounds like a complete list of the relevant items being mentioned.

A learner might compare it with や:

• 油絵や彫刻 = things like oil paintings and sculptures

So と is more direct and complete, while や suggests examples and an incomplete list.

この means this and must come before a noun.

So:

• この展示 = this exhibition / this display

You cannot use この by itself as a pronoun. It must modify a noun.

Compare:

• この展示 = this exhibition
• これ = this one / this thing

So if you want a noun after this, use この + noun.

展示 can mean display or exhibition, depending on context.

In this sentence, either this exhibition or this display could work, but this exhibition is often the more natural English translation if we are talking about art like oil paintings and sculptures.

A related word is 展覧会, which more specifically means an exhibition/art exhibition.
But 展示 is also very common and natural when talking about exhibited items.

Japanese nouns usually do not change form for singular vs. plural.

So:

• 油絵 can mean an oil painting or oil paintings
• 彫刻 can mean a sculpture or sculptures

The context tells you whether singular or plural is meant.
Because two art categories are being listed, English often translates them as plurals here.

This is very normal in Japanese.

The sentence is read:

この てんじ には、あぶらえ と ちょうこく が あります。

Word by word:

• この = kono
• 展示（てんじ） = tenji
• には = ni wa
• 油絵（あぶらえ） = aburae
• と = to
• 彫刻（ちょうこく） = chōkoku
• が = ga
• あります = arimasu

A note on pronunciation:

• は is written ha but pronounced wa when used as the topic particle.
• が is still pronounced ga.

Japanese word order is more flexible than English, but not completely free.

This sentence follows a very common pattern:

• この展示には、油絵と彫刻があります。

You could also say:

• 油絵と彫刻がこの展示にはあります。

That is grammatical, but it sounds more marked or emphatic.
The original order is the most natural in ordinary explanation or description.

In general, putting the location/topic first is very common with あります.

Because に is used for the place where something exists, while で is used for the place where an action happens.

Here, the sentence is about existence:

• there are oil paintings and sculptures

So に is correct.

Compare:

• この展示には油絵があります。
  • There are oil paintings in this exhibition.
• この展示で写真を撮ります。
  • I take pictures at this exhibition.

So:

• existence → に
• action → で

No. Normally, Japanese is written without spaces between words.

So the standard writing would be:

この展示には、油絵と彫刻があります。

Spaces are often added in teaching materials to help beginners see the word boundaries more clearly.

Yes. Even though the Japanese structure is literally closer to In this exhibition, there are oil paintings and sculptures, natural English may also say:

• This exhibition has oil paintings and sculptures.

Japanese often expresses possession with an existence structure instead of using a direct verb like have.

So a very common pattern is:

• X には Y がある
  • X has Y
  • In X, there is Y

Both English translations can be right depending on style.
