In Mandarin, time words usually come early in the sentence, often before the verb phrase.

So this pattern is very common:

Subject + time + adverb + verb

Here:

• 她 = she
• 每天晚上 = every evening
• 都 = always / in every case
• 会整理桌子 = will / tends to tidy the desk

So 她每天晚上都会整理桌子 feels very natural.

A rough word-order guide is:

She + every evening + always + tidies the desk

That is different from English, where time expressions are often more flexible.

Because 每天晚上 means every evening, with 每天 modifying 晚上.

Think of it like this:

• 每天 = every day
• 晚上 = evening / at night

Together, 每天晚上 means every day in the evening.

晚上每天 sounds unnatural because it puts the broader time word after the narrower one in a way Mandarin usually does not prefer here.

Similar natural expressions:

• 每天早上 = every morning
• 每天下午 = every afternoon
• 每天晚上 = every evening

Great question. 都 does not only mean all with plural nouns. It can also be used with words like 每天, 每次, 周末, etc. to emphasize every time / on each occasion / consistently.

Here, 每天晚上 already means every evening, and 都 reinforces that repeated idea:

• 她每天晚上整理桌子 = She tidies the desk every evening.
• 她每天晚上都整理桌子 = She tidies the desk every evening / every single evening.

So 都 adds a sense of without exception or regularly each time.

Here 会 is not mainly about ability. It suggests a habit, tendency, or something that normally happens.

So in this sentence, 会整理桌子 is closer to:

• will tidy
• tends to tidy
• usually tidies

It does not strongly mean knows how to tidy.

Compare:

• 她会说中文。 = She can speak Chinese. → ability
• 她每天晚上都会整理桌子。 = She will / usually tidies the desk every evening. → habitual action

So the meaning depends on context.

Yes, it can.

You could say:

她每天晚上都整理桌子，所以房间不太乱。

This is still natural and probably even a little more straightforward for a beginner.

The version with 会 adds a slight feeling of:

• regular habit
• predictable behavior
• what she normally does

So:

• 都整理 = tidies every evening
• 都会整理 = will/usually tidies every evening, as a regular habit

Both are fine.

Because in this kind of sentence, 都 usually comes before the modal verb 会.

So:

• 她每天晚上都会整理桌子 = natural
• 她每天晚上会都整理桌子 = unnatural

A simple way to remember it is:

time + 都 + modal + verb

Examples:

• 他每天都要工作。
• 我们周末都会去。
• 她每次都会笑。

So 都 comes before 会 in this pattern.

整理 usually means put in order, organize, or tidy up.

So 整理桌子 means something like:

• tidy the desk
• organize the desk
• put the desk in order

It is not exactly the same as clean in the sense of wiping dirt off. If you wanted to emphasize cleaning, you might use:

• 擦桌子 = wipe the table/desk
• 打扫 = clean up
• 收拾桌子 = tidy up the desk / clear the desk

So 整理 focuses more on order and arrangement than on dirt.

Mandarin does not use articles like a or the.

So 桌子 can mean:

• a desk
• the desk
• her desk
• the table

The exact meaning comes from context.

Also, measure words are not used here because 桌子 is the direct object of the verb, not something being counted.

Compare:

• 她整理桌子。 = She tidies the desk.
• 一张桌子 = one desk/table

So when you are just talking about the object of an action, the noun often appears by itself.

所以 means so or therefore. It connects the first clause and the result:

• 她每天晚上都会整理桌子 = She tidies the desk every evening.
• 所以房间不太乱 = so the room is not too messy.

It is not always necessary, but it makes the cause-and-effect relationship very clear.

You could also say: 她每天晚上都会整理桌子，房间不太乱。

That is understandable, but 所以 makes the logic more explicit and natural in many contexts.

Because 不太乱 is softer and more natural in many everyday situations.

Compare:

• 不乱 = not messy
• 不太乱 = not too messy / not very messy

不乱 can sound stronger, almost like it is tidy. 不太乱 sounds more moderate and realistic: maybe the room is not perfectly neat, but it is not very messy.

Mandarin often prefers this kind of softer expression.

By itself, 太 + adjective often means too...

Example:

• 太乱了 = too messy

But in 不太 + adjective, it usually means:

• not very...
• not too...

So:

• 不太乱 = not very messy / not too messy
• 不太大 = not very big
• 不太好 = not very good

This is a very common pattern in Mandarin.

Logically, the sentence suggests that tidying the desk helps keep the room from becoming too messy. It does not mean the desk is the only thing in the room, or that the room is perfectly clean.

This kind of statement is normal in Mandarin and English:

• She tidies her desk every evening, so the room is not too messy.

It gives a general result, not a strict scientific cause.

Because Mandarin often leaves out information that is already clear from context.

If we already know we are talking about her habits and her room/desk, then saying only:

• 整理桌子
• 房间不太乱

is perfectly natural.

If you want to be more explicit, you could say:

• 她每天晚上都会整理她的桌子，所以她的房间不太乱。

But that sounds more repetitive. Mandarin often prefers the shorter version when ownership is obvious.

Because the second syllables -shang in 晚上 and -zi in 桌子 are often pronounced in a neutral tone.

So:

• 晚 = wǎn
• 上 = neutral tone here → shang
• 桌 = zhuō
• 子 = neutral tone here → zi

This is very common in everyday Mandarin. Many second syllables in common nouns or time words become lighter and shorter.

So learners should not pronounce them too heavily as full fourth or third tones in this sentence.
