míngtiān wǒmen qīdiǎn zài xuéxiào ménkǒu jiànmiàn ba.

Chinese often puts information in this order:

time → subject → smaller time → place → verb → sentence particle

So here, the sentence moves from a broad time frame to the action:

• 明天 = tomorrow
• 我们 = we
• 七点 = seven o’clock
• 在学校门口 = at the school gate / entrance
• 见面 = meet
• 吧 = suggestion particle

A very natural way to think about it is: first set the scene, then say what happens.

Yes, 明天 is often placed at the beginning because Chinese likes to start with the time frame for the whole sentence.

So this is natural:

• 明天我们七点在学校门口见面吧。

But these are also possible:

• 我们明天七点在学校门口见面吧。
• 明天七点我们在学校门口见面吧。

The meaning stays basically the same. The difference is mostly about what comes first in the speaker’s mind or what gets a little more emphasis.

Because they give different kinds of time information:

• 明天 = the day
• 七点 = the specific hour

Chinese commonly uses both together. Usually the bigger time unit comes before the smaller one:

• 明天七点
• not usually 七点明天

This is similar to going from general to specific.

In Chinese, clock times usually do not need a preposition like at.

So you simply say:

• 七点 = at seven / seven o’clock

This is very normal in Chinese. The time expression directly tells you when something happens.

Examples:

• 我八点上课。 = I have class at 8.
• 我们明天七点见面。 = We’ll meet at 7 tomorrow.

在 introduces the location of the action. Here it means at or in.

• 在学校门口 = at the school entrance / gate

So 在 is marking where the meeting will happen.

A useful pattern is:

• 在 + place + verb

For example:

• 在家吃饭 = eat at home
• 在学校学习 = study at school

Because in Chinese, location phrases introduced by 在 usually come before the main verb.

So the pattern is:

• 在 + place + verb

Here:

• 在学校门口见面 = meet at the school gate

This is different from English, which often puts the place later:

• meet at the school gate

Chinese usually places that location information before the action.

Both can exist, but 学校门口 is the more natural and compact expression here.

In Chinese, when two nouns are closely connected, 的 is often omitted:

• 学校门口 = school entrance / gate area
• literally something like school entrance

Using 学校的门口 is not impossible, but it sounds less compact and a bit more explanatory. In everyday speech, 学校门口 is what learners will hear much more often.

This is common in Chinese:

• 教室门口 = classroom door / classroom entrance
• 公司门口 = company entrance
• 家门口 = in front of one’s home / at one’s doorstep

门口 literally means doorway, entrance, or the area by the door/gate.

With a place like a school, it often means the school gate or the entrance area, not just the physical door itself.

So 学校门口 usually means the spot where people gather at the entrance to the school.

见面 means to meet or to see each other, and it often has a mutual sense: two sides are meeting each other.

That is why it works well with 我们.

A key point: 见面 usually does not take a direct object the way English meet does.

So instead of saying something like 见面他, Chinese usually says:

• 跟他见面
• 和他见面

Both mean meet with him.

In this sentence, 我们见面 is very natural because the subject already includes both people involved in the meeting.

吧 softens the sentence and turns it into a suggestion, proposal, or gentle invitation.

Here it gives a feeling like:

• let’s meet
• how about we meet
• shall we meet

Without 吧, the sentence sounds more like a plain statement of fact or plan.

Compare:

• 明天我们七点在学校门口见面。
  = Tomorrow we’re meeting at 7 at the school gate. / We will meet...

• 明天我们七点在学校门口见面吧。
  = Let’s meet tomorrow at 7 at the school gate.

So 吧 is very important for the tone.

Not always. If the context already makes it clear, 七点 by itself is enough.

But if it could be unclear, Chinese often adds a time-of-day word:

• 明天早上七点 = tomorrow at 7 in the morning
• 明天下午七点 is not natural, because 7 is usually evening
• 明天晚上七点 = tomorrow at 7 in the evening

So 七点 alone is fine when both speakers already know which 7 o’clock is meant.

Yes. That is completely natural.

Chinese allows some flexibility with time expressions, especially when they stay before the main verb. These are all natural:

• 明天我们七点在学校门口见面吧。
• 明天七点我们在学校门口见面吧。
• 我们明天七点在学校门口见面吧。

The main thing is that the time and place information usually comes before 见面.

Because the sentence is focusing on the meeting itself, not the movement to the place.

• 见面 already tells us the main action: meeting
• 在学校门口 tells us where that meeting happens

So there is no need to add 去 unless you specifically want to emphasize going there.

For example:

• 我们明天七点去学校门口见面吧。

This is possible, but it adds a stronger sense of go to the school gate to meet. In many cases, it is unnecessary, so the simpler sentence is more natural.
