Guò le jǐ gè yuè, tā zhōngyú shìyìng le xiàoyuán de huánjìng.

The two 了 both mark completed actions, but they belong to different verbs:

• 过了几个月 – 了 here marks that the action 过 (to pass) is completed: a few months had passed.
• 适应了校园的环境 – 了 here marks that 适应 (to get used to) is completed: she (finally) adapted to the campus environment.

So the structure is like English:
“After a few months had passed, she finally got used to the campus environment.”

Two completed actions → two 了 are natural.

Here 过 is a verb, not the experiential aspect marker.

• Verb 过 = “to pass (time, a place, etc.)”
  
  • 过了几个月 = “(several) months have passed”
• Aspect marker 过 (after a verb) = “have done / have experienced”:
  
  • e.g. 去过中国 = “have been to China”

You can tell it’s the verb because it comes before the time expression 几个月 and is followed by 了. With the experiential marker, you’d have Verb + 过 + Object, not 过 + 了 + Time.

Yes, you could say:

• 几个月以后，她终于适应了校园的环境。
• 几个月后，她终于适应了校园的环境。

Differences:

• 过了几个月 literally: “after a few months have passed” – it feels very natural and slightly more process‑focused (time has passed).
• 几个月以后 / 几个月后 literally: “after a few months / a few months later” – a bit more neutral / calendar-like.

In everyday speech and writing, all three are common and acceptable. The nuance difference is small; 过了几个月 slightly emphasizes the passage of time.

Because in Mandarin, most nouns need a measure word (classifier) when they are counted or quantified.

• 几 = “a few / several”
• 月 = “month”
• The measure word for “month” in this kind of duration expression is 个.

So:

• ✅ 几个月 (correct and standard)
• ❌ 几月 (would usually be understood as “which month?” in a different context, not “a few months”)

Other common time+measure patterns:

• 三天 (no 个)
• 三个星期 / 三周
• 两年 (no 个)

For months of duration, 个 is normally required: 一个月 / 几个月 / 三个月.

Yes, that sentence is grammatically correct:

• 她过了几个月终于适应了校园的环境。

However, the most natural word order in Chinese is often:

1. Time / setting at the beginning
2. Then subject + predicate

So:

• 过了几个月，她终于适应了校园的环境。
  feels smoother and more typical than putting 过了几个月 after 她.

You’ll very often see patterns like:

• 三年以后，他回到了家乡。
• 那天晚上，我们看了一部电影。

适应 (shìyìng) means “to adapt (to), to get used to”.

Usage:

• It is a verb that directly takes an object:
  • 适应环境 – adapt to the environment
  • 适应新工作 – get used to a new job
  • 适应大学生活 – adapt to university life

In this sentence:

• 适应了校园的环境 = “(she) got used to the campus environment / adapted to the campus environment.”

You don’t need a preposition before the object in this pattern. It’s simply 适应 + [thing you adapt to].

No. In this structure, 适应 takes a direct object, so 对 is not used:

• ✅ 适应校园的环境
• ❌ 适应对校园的环境

You can see 对 with 适应 in a different pattern, like:

• 她对这里的生活很适应。
  “She is very well adapted to the life here.”

Two patterns:

1. 适应 + Object
   
   • 适应环境 / 适应新学校
2. 对 + Object + 很适应
   
   • 对新环境很适应

Don’t mix the two.

的 links an attributive (modifier) to a noun:

• 校园的环境 = “the environment of the campus / the campus’s environment”

Both are possible:

• 校园的环境 – very clear, neutral, slightly more formal.
• 校园环境 – also common; sounds a bit more like a compact noun phrase or “set phrase”.

In many cases:

• X 的 Y ≈ XY as a noun compound, especially with short, simple modifiers.

Here:

• 校园的环境 and 校园环境 both sound natural. The 的 is optional and doesn’t change the meaning much.

Both relate to “school,” but the focus is different:

• 学校 (xuéxiào) – the school as an institution:

  • the organization, the place you attend
  • e.g. “my school,” “this school is famous”

• 校园 (xiàoyuán) – the campus:

  • the physical grounds and environment: buildings, lawns, atmosphere
  • often used for middle schools, high schools, universities, etc.

In this sentence, 校园的环境 highlights the campus environment (physical + social atmosphere), which fits the idea of “getting used to” a new place.

Both can be translated as “finally,” but they’re used differently:

• 终于 (zhōngyú):

  • Emphasizes a long wait / difficulty and a desired or expected result.
  • Often has an emotional flavor: relief, satisfaction.
  • 她终于适应了校园的环境。
    → “She finally (at last) got used to the campus environment.”
    Implies this was something she had been struggling with.

• 最后 (zuìhòu):

  • Mainly means “in the end / at last / the last step.”
  • Focuses on sequence, not necessarily on desire or effort.
  • 最后，他回家了。 – In the end, he went home.
  • 最后一个问题 – the last question.

In this sentence, 终于 is better, because we’re talking about a slow process reaching a hoped‑for state.

Yes, that sentence is also natural:

• 过了几个月，她终于适应校园的环境了。

Subtle nuance:

• 适应了校园的环境。
  – Focus on the completion of the action “got used to.”
• 适应校园的环境了。
  – Slightly more focus on the new state now being true (a “change of state” feeling): Now she’s used to it.

In everyday conversation the difference is small; both versions are fine. Chinese often allows the sentence‑final 了 to mark “and now the situation has changed.”

环境 (huánjìng) is broad and can include:

• Physical surroundings (buildings, layout, weather)
• Social environment (people, relationships)
• Cultural / academic atmosphere

In 校园的环境, it naturally suggests the overall campus environment: physical, social, and academic. So she is getting used not just to the buildings, but also to the people, routines, and atmosphere of campus life.
