Both 我们老师 and 我们的老师 can mean our teacher.

In Chinese, when the relationship is close or familiar—especially with people, family, school, or workplace roles—the 的 is often omitted. So:

• 我们老师 = our teacher
• 我们学校 = our school
• 我妈妈 = my mom

Using 我们的老师 is also grammatical, but 我们老师 sounds more natural and conversational here.

说 means to say / to tell / to speak, and Chinese verbs do not change form for tense the way English verbs do.

So 我们老师说 could mean:

• Our teacher says...
• Our teacher said...

The exact time usually comes from context, not from changing the verb itself.

If you want to make the past clearer, you could add a time word, for example:

• 昨天我们老师说... = Yesterday our teacher said...

In this sentence, says is often the most natural translation if it is giving general advice.

The comma separates the reporting part from the content being reported.

• 我们老师说，... = Our teacher said, ...

Everything after the comma is what the teacher said:

• 感冒的时候最好别喝太多冰饮料。

This is very common in Chinese writing.

感冒的时候 means when you have a cold or when you catch a cold, depending on context.

Breakdown:

• 感冒 = to catch a cold / to have a cold
• 的时候 = when / at the time when

So:

• 感冒的时候 = when one has a cold

In this sentence, it means when you have a cold.

In A 的时候, 的时候 means when A happens or during the time A is happening.

So:

• 吃饭的时候 = when eating
• 下雨的时候 = when it rains
• 感冒的时候 = when you have a cold

The 的 links the action/state to 时候.

You may also hear shorter forms in Chinese, such as:

• 感冒时

This is more concise and a bit more formal.
感冒的时候 sounds very natural in everyday speech.

最好 here means it’s best to or had better.

It does not mean the best in the noun/adjective sense here. Instead, it is being used adverbially to give advice:

• 最好别喝太多冰饮料 = It’s best not to drink too many cold drinks.

A useful pattern is:

• 最好 + verb phrase

Examples:

• 最好早点睡。 = It’s best to sleep early.
• 最好别去。 = It’s best not to go.

别 is used for negative commands or advice not to do something.

So:

• 别喝 = don’t drink

This is different from 不, which usually states a fact or habit:

• 我不喝咖啡。 = I don’t drink coffee.

In this sentence, the teacher is giving advice, so 别 is the right choice:

• 最好别喝... = it’s best not to drink...

You could also say:

• 最好不要喝...

This sounds slightly fuller and a bit softer, but the meaning is very similar.

The structure is:

• 最好 = it’s best
• 别喝 = not drink / don’t drink
• 太多冰饮料 = too many / too much cold drinks

So the whole phrase means:

• it’s best not to drink too many cold drinks

Chinese often stacks these parts directly in front of the main verb phrase, which can feel compact to English speakers.

A very common pattern is:

• 最好别 + verb

For example:

• 最好别迟到。 = It’s best not to be late.
• 最好别吃这个。 = It’s best not to eat this.

太多 means too much / too many.

In this sentence, it modifies the amount of 冰饮料:

• 喝太多冰饮料 = drink too many / too much cold drinks

In English, whether you say too much or too many depends on how you interpret 饮料:

• as a countable idea: too many cold drinks
• as an uncountable amount: too much cold drink

In natural English, too many cold drinks is usually the best translation here.

Because 太多 can directly modify a noun in many cases.

So:

• 太多冰饮料 = too many cold drinks

You do not need a measure word here.

Chinese often allows quantity words like 很多, 太多, 一些 to come directly before nouns.

Examples:

• 很多人 = many people
• 太多问题 = too many problems
• 一些水 = some water

冰饮料 means drinks that are cold, chilled, or iced—so cold drinks or iced drinks are both possible translations.

Breakdown:

• 冰 = ice / icy / cold
• 饮料 = beverage / drink

In everyday English, cold drinks is usually the most natural translation.

In Chinese, nouns often modify other nouns directly without 的, especially in common fixed combinations.

So:

• 冰饮料 = cold/iced drinks

This is similar to other combinations like:

• 中文老师 = Chinese teacher
• 水果店 = fruit shop
• 冬天衣服 = winter clothes

You could say 冰的饮料, but it sounds less natural here and more like you are emphasizing drinks that are cold as a description rather than using the standard compound noun.

The subject is omitted because it is general advice.

Chinese often leaves out subjects when they are obvious or meant generally. Here, the meaning is like:

• When you have a cold, it’s best not to drink too many cold drinks.

The implied subject could be:

• you
• people
• someone
• we

depending on context. English usually needs a subject, but Chinese often does not.

Yes. 感冒 is commonly used both ways.

It can mean:

• to catch a cold
• to have a cold
• a cold (the illness)

Examples:

• 我感冒了。 = I caught a cold / I have a cold.
• 感冒的时候要多休息。 = When you have a cold, you should rest more.

In this sentence, it refers to the state of having a cold.

It is giving advice, not a harsh command.

That soft advisory tone comes from:

• 我们老师说 = our teacher says
• 最好 = it’s best
• 别 = don’t / better not

So the feeling is:

• Our teacher says that when you have a cold, it’s best not to drink too many cold drinks.

It sounds like recommendation or health advice, not an order.

Yes.

You could say:

• 感冒的时候最好不要喝太多冰饮料。

This means almost the same thing.

Comparison:

• 别 = shorter, very common in speech
• 不要 = slightly more explicit and sometimes a little gentler or more formal

Both are natural here.

Yes. The order is very natural.

The sentence is:

• 我们老师说，感冒的时候最好别喝太多冰饮料。

You can think of it as:

1. 我们老师说 = Our teacher says
2. 感冒的时候 = when you have a cold
3. 最好 = it’s best
4. 别喝太多冰饮料 = not to drink too many cold drinks

Chinese often puts time expressions early, before the main action. So 感冒的时候 comes before 最好别喝...

That is very normal Chinese structure.
