本来 means originally, at first, or to begin with.

In this sentence, 她本来想参加下午的会议 shows that attending the meeting was her original plan, but something changed afterward.

So the feeling is:

• At first, she wanted to attend the afternoon meeting
• but later, because she felt unwell, that plan changed

It often introduces a contrast between an earlier intention and what actually happened.

Here 想 mainly means wanted to or was planning to.

So:

• 她本来想参加下午的会议 = She originally wanted to attend the afternoon meeting = She had been planning to attend the afternoon meeting

In real usage, 想 + verb can mean:

• want to do something
• be thinking of doing something
• sometimes intend to do something

So in this sentence, it is less about a sudden desire and more about a prior plan or intention.

的 links a modifier to a noun.

Here:

• 下午 = afternoon
• 会议 = meeting
• 下午的会议 = the afternoon meeting / the meeting in the afternoon

So 下午 is modifying 会议, and 的 connects them.

A useful pattern is:

• time/place/description + 的 + noun

Examples:

• 今天的课 = today’s class
• 学校的老师 = the school’s teachers / teachers at the school
• 下午的会议 = the afternoon meeting

Yes. In English, both are natural translations.

Chinese often does not force the same distinction English does. 下午的会议 simply describes a meeting associated with the afternoon.

Depending on context, it could mean:

• a meeting scheduled for the afternoon
• the meeting that takes place in the afternoon
• that particular afternoon meeting everyone already knows about

Because 会议 here is being treated as a specific event, not just one meeting in a counting sense.

• 参加下午的会议 = attend the afternoon meeting
• 参加一个会议 = attend a meeting

When a noun is already made specific by context or by a modifier, Chinese often does not need a measure word.

So:

• 下午的会议 sounds natural and specific
• 一个下午的会议 would usually sound wrong here
• 一个会议 would mean a meeting, but that is less specific than the original sentence

可是 means but.

In this sentence, it introduces a contrast:

• she originally wanted to attend the meeting
• but she did not feel well

So:

• 她本来想参加下午的会议，可是身体不舒服 = She originally wanted to attend the afternoon meeting, but she wasn’t feeling well

As for 可是 vs 但是:

• both mean but
• both are very common
• 可是 often sounds a little more conversational
• 但是 can sound slightly more neutral or formal

In many everyday sentences, they are interchangeable.

Because Chinese often omits things that are already clear from context.

The subject 她 has already appeared at the beginning of the sentence, so it does not need to be repeated:

• 她本来想参加下午的会议，可是身体不舒服
• literally: She originally wanted to attend the afternoon meeting, but [her] body was unwell

In natural English, we would say but she wasn’t feeling well, but in Chinese it is very common to drop the repeated subject when it is obvious.

You could say 可是她身体不舒服, and that is grammatical, but the original sentence sounds smooth and natural.

身体不舒服 literally means the body is not comfortable, but in natural English it usually means:

• not feeling well
• feeling unwell
• feeling sick

It does not always mean a serious illness. It can refer to anything from mild discomfort to being sick enough to rest.

Compared with some other words:

• 生病 = to be ill / to be sick
• 不舒服 = uncomfortable / unwell
• 身体不舒服 = physically unwell

So 身体不舒服 is a very natural and common way to say someone is not feeling well physically.

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:

• 舒 is first tone, so you might expect bùshūfu
• but in standard pinyin for this word, the common pronunciation is búshūfu

This word is a special case in everyday speech and is very commonly pronounced búshūfu.

So for learners, the safest thing is simply to remember:

• 不舒服 → usually said as búshūfu

只好 means to have no choice but to.

This is stronger than simply saying then or so. It tells us that the speaker had to do something because the situation left no better option.

In this sentence:

• 只好回宿舍睡觉 = had no choice but to go back to the dorm and sleep

Compare:

• 就回宿舍睡觉 = then went back to the dorm and slept
• 于是回宿舍睡觉 = therefore / as a result, went back to the dorm and slept
• 只好回宿舍睡觉 = had no choice but to go back to the dorm and sleep

So 只好 adds the idea of reluctant necessity.

This is a very common Chinese structure called serial verb construction.

Chinese often places actions one after another directly:

• 回宿舍睡觉 = go back to the dorm and sleep = return to the dorm to sleep

The relationship between the verbs is understood from context. English usually needs words like and, to, or in order to, but Chinese often does not.

So this part can be understood as:

1. 回宿舍 = go back to the dorm
2. 睡觉 = sleep

Together:

• go back to the dorm to sleep

回 means return or go back, while 去 just means go.

Using 回宿舍 suggests that the dorm is the place she normally stays, so she is returning to it.

• 回宿舍 = go back to the dorm
• 去宿舍 = go to the dorm

If she lives there, 回宿舍 is more natural.

So the sentence implies that the dorm is her usual place, not just some random destination.

睡觉 literally means sleep or go to sleep, and in many contexts it can also be translated as go to bed.

Its exact English translation depends on context.

For example:

• 我要睡觉了。 = I’m going to sleep. = I’m going to bed.

In this sentence:

• 回宿舍睡觉 most naturally means go back to the dorm and sleep

The important idea is rest, not just the physical act of lying in bed.

Yes. 参加 is a very common verb meaning participate in, join, or attend.

It is often used for events and activities such as:

• 参加会议 = attend a meeting
• 参加比赛 = take part in a competition
• 参加活动 = participate in an event
• 参加婚礼 = attend a wedding

So 参加下午的会议 is completely natural.

The sentence can be broken down like this:

• 她本来想参加下午的会议 = She originally wanted to attend the afternoon meeting

• 可是身体不舒服 = but she wasn’t feeling well

• 只好回宿舍睡觉 = so she had no choice but to go back to the dorm and sleep

So the overall pattern is:

• original plan
• problem/contrast
• forced result

This is a very useful structure in Chinese:

• 本来……，可是……，只好……

For example:

• 我本来想出去，可是下雨了，只好待在家里。 = I originally wanted to go out, but it rained, so I had no choice but to stay home.

You could translate it literally that way, but it would sound unnatural in English.

Chinese often expresses physical condition with 身体 in a way that English does not. So although:

• 身体不舒服 literally looks like body not comfortable

the natural English meaning is:

• she wasn’t feeling well
• she felt unwell
• she felt sick

When translating, it is better to use natural English rather than sticking too closely to the word-for-word structure.

Yes, it helps show the sentence has two major parts:

1. what she originally intended to do
2. what actually happened instead

In Chinese writing, punctuation is important for readability, especially in longer sentences. The comma before 可是 marks the shift from the first idea to the contrast.

The second comma, before 只好, marks the next step:

• cause/problem: 身体不舒服
• result: 只好回宿舍睡觉

So the commas help the reader follow the logic of the sentence.

Yes. All of those are possible depending on style.

• 宿舍 is a general word for shared living quarters, often for students or workers
• in student contexts, dorm or dormitory is usually the most natural translation
• residence hall is possible in more formal American English, but less direct as a basic vocabulary translation

So in this sentence:

• 回宿舍睡觉 is most naturally go back to the dorm and sleep
