zhè cì wǒ bú qù chāoshì.

这次 means this time or on this occasion.

• 这 = this
• 次 = a measure word for occurrences, times, or instances

So 这次 is not about physical size or number of objects; it is about one occasion/event.

You will see 次 in phrases like:

• 一次 = one time / once
• 两次 = two times
• 下次 = next time
• 上次 = last time

In this sentence, 这次 sets the context: this time, as opposed to other times.

Yes, 我这次不去超市 is also correct.

Both are natural, but the emphasis is a little different:

• 这次我不去超市。
  Emphasizes this time
• 我这次不去超市。
  Emphasizes I or simply sounds a bit more neutral in conversation

Chinese often puts time expressions near the beginning of the sentence. A very common pattern is:

Time + Subject + 不/没 + Verb + Object

So 这次我不去超市 follows a very common structure.

This is because of tone sandhi.

Normally, 不 is fourth tone: bù.
But when 不 comes before another fourth-tone syllable, it changes to second tone: bú.

Here:

• 不 = usually bù
• 去 = qù (fourth tone)

So:

• 不去 is pronounced bú qù

This change is about pronunciation, not meaning.

不 and 没 are both negative words, but they are used differently.

In this sentence, 不去 means not go / am not going / don’t go in a present or future sense, or it can express a decision/refusal.

Use 不 for:

• habits
• general statements
• present/future actions
• intentions or choices

Use 没 for:

• things that did not happen
• past non-completion
• have not done something

So:

• 这次我不去超市。 = This time I’m not going to the supermarket.
• 这次我没去超市。 = This time I didn’t go to the supermarket.

That is a very important difference.

Because in Chinese, the verb 去 already means to go (to a place), and the destination usually comes directly after it.

So:

• 去超市 = go to the supermarket
• 去学校 = go to school
• 去北京 = go to Beijing

English needs to, but Chinese does not use a separate word here.

Chinese does not have articles like a, an, and the.

So 超市 can mean:

• a supermarket
• the supermarket
• sometimes just supermarket

The exact meaning depends on context.

That means Chinese learners of English have to add articles, but English speakers learning Chinese have to get used to not using them.

超市 is the common short form of 超级市场, and it usually means supermarket.

In everyday speech, 超市 is much more common than the full form.

Depending on context, it can refer to:

• a grocery-style supermarket
• a large general store
• sometimes a place similar to a hypermarket

But for most learners, thinking of 超市 as supermarket is perfectly fine.

Yes. 这次 and 这一次 are both correct.

• 这次 = more common and concise
• 这一次 = slightly fuller, sometimes a bit more emphatic

So these are both natural:

• 这次我不去超市。
• 这一次我不去超市。

In everyday spoken Mandarin, 这次 is very common.

It can do both.

At the basic level, it means:

• This time, I’m not going to the supermarket.

But 这次 often implies contrast with other occasions, such as:

• maybe I usually go, but not this time
• maybe others are going, but I’m not
• maybe I went before, but not now

Chinese often leaves that contrast unstated, and listeners understand it from context.

Yes, in the right context.

Chinese often drops the subject when it is already clear. So if everyone knows you are talking about yourself, you can say:

• 这次不去超市。

That sounds natural in conversation.

However, including 我 is clearer and better for learners:

• 这次我不去超市。

It is best understood as verb + destination/place.

• 去 = go
• 超市 = supermarket

So 超市 is the place you are going to.

This is different from a direct object in English grammar terms, but for learners, the key point is simple:

After 去, you usually put the destination directly.

Examples:

• 去商店 = go to the shop
• 去公司 = go to the office
• 去医院 = go to the hospital

A useful way to see it is:

Time expression + Subject + Negation + Verb + Place

So here:

• 这次 = time/occasion expression
• 我 = subject
• 不 = negation
• 去 = verb
• 超市 = place

This pattern is very common in Mandarin, and learning it will help you make many similar sentences. For example:

• 今天我不去学校。 = Today I’m not going to school.
• 明天他不来公司。 = Tomorrow he isn’t coming to the office.
• 这周我们不出去吃饭。 = This week we aren’t going out to eat.
