Both 了s mark completed actions.

• 问了她的症状 = asked about her symptoms
• 给她量了体温 = took her temperature

In this sentence, 了 is the sentence’s way of showing that each action happened and was completed. It does not mean the same thing as English already in every case; here it mainly marks past/completed events in a narrative.

先...然后... means first... then...

So:

• 医生先问了她的症状 = The doctor first asked about her symptoms
• 然后又给她量了体温 = then also took her temperature

This pattern is very common for describing actions in order.

又 often means again, but here it is better understood as then also / in addition.

So 然后又给她量了体温 means something like:

• then also took her temperature
• then went on to take her temperature

It does not necessarily mean the doctor had taken her temperature before and repeated it. In narration, 又 can connect one action to another and add the sense of and then also.

她的症状 means her symptoms. The particle 的 marks possession.

So:

• 她的症状 = her symptoms

Without 的, 她症状 is not natural here.

A learner may also expect 问她有什么症状. That is also natural and slightly fuller:

• 问她有什么症状 = ask her what symptoms she has

But 问她的症状 is a shorter, compact way to express ask about her symptoms.

In Chinese, with close personal things like body parts and bodily conditions, 的 is often omitted when the owner is already clear.

So these are both possible in principle:

• 给她量体温
• 给她量她的体温

But the first one is much more natural and common.

This is similar to how Chinese often says:

• 洗手 = wash one’s hands
• 抬头 = raise one’s head

When the person is obvious, Chinese often does not repeat the possessive.

Here 给 means something like for or to and introduces the person receiving the action.

• 给她量体温 = take her temperature / measure the temperature for her

The structure is:

• 给 + person + verb + object

Examples:

• 给他看病 = treat him / see him as a patient
• 给我看看 = let me take a look

So 给她量体温 literally feels like measure body temperature for her.

Because 量 has more than one pronunciation.

Here, 量 means to measure, so it is pronounced liáng.

Common distinction:

• liáng = to measure
  
  • 量体温 = measure/take temperature
  • 量长度 = measure length
• liàng = quantity / amount / capacity
  
  • 数量 = quantity
  • 饭量 = appetite, how much one can eat

So in this sentence, it must be liáng because it is a verb meaning measure.

Chinese nouns usually do not change form for singular vs. plural the way English nouns do.

So 症状 can mean:

• symptom
• symptoms

The exact meaning depends on context. In a medical sentence like this, English naturally uses symptoms, but Chinese does not need a special plural ending.

Yes. 问 often means to ask, but in context it can also mean ask about.

So:

• 问了她的症状 literally looks like asked her symptoms
• natural English: asked about her symptoms

Chinese often leaves out words that English needs. The meaning is understood from context.

Chinese word order here is very natural as:

• 给她 = for her / to her
• 量了 = measured
• 体温 = body temperature

So the pattern is:

• 给 + person + verb + object

This is the normal way to say it.
量了她的体温 is also possible in some contexts and means measured her temperature, but 给她量了体温 sounds especially natural when focusing on the action done to/for the person.

Yes. 医生 just means doctor and does not show gender.

If you want to know whether the doctor is male or female, the word itself does not tell you. You would need extra context.

The comma separates two sequential actions:

1. 医生先问了她的症状
2. 然后又给她量了体温

This kind of punctuation is very common in Chinese when one sentence describes several actions in order. It makes the timeline easier to follow.

Yes, sometimes.

Possible alternatives include:

• 接着 = then, next
• 随后 = afterward, subsequently

For example:

• 医生先问了她的症状，接着又给她量了体温。

That is also natural.
But 然后 is one of the most common and neutral choices, so it is a very good word to learn first.

Mostly, yes. In this sentence, the completed-action 了s make it clear that these events happened as finished steps in a sequence.

But more broadly, Chinese does not have tense in the same way English does. Chinese often shows time through:

• context
• time words
• aspect markers like 了

So 了 here is not exactly a past-tense ending. It is better to think of it as showing that the actions were completed.
