Tā píngshí hěn guānxīn biéren, shēngyīn yě zǒngshì bú dà.

平时 means in ordinary times, normally, or in daily life. It often contrasts with special situations.

In this sentence, 他平时很关心别人 suggests:

• this is his usual behavior
• not just something he did once

Compared with similar words:

• 平时 = in everyday life / under normal circumstances
• 通常 = usually, often a bit more neutral or formal
• 一般 = generally / in general

So 平时 gives a slightly more personal, everyday feeling here.

Yes, 很 here means very, so 很关心别人 means cares a lot about others or is very considerate of others.

But there is also an important grammar point: in Mandarin, words like 很 are very commonly used before descriptive predicates. Even when English would not say very, Chinese often prefers to include a degree word.

Here, though, 很 really does add meaning:

• 关心别人 = care about others
• 很关心别人 = care a lot about others

So in this sentence, 很 is both natural and meaningful.

关心 is mainly a verb, meaning to care about, to be concerned about, or to show concern for.

Examples:

• 他关心别人。 = He cares about others.
• 老师很关心学生。 = The teacher cares a lot about the students.

In English, we might describe someone as caring, but in Chinese the wording is often verbal: care about others.

So in 他平时很关心别人, the structure is:

• 他 = he
• 平时 = usually / in daily life
• 很关心 = cares a lot
• 别人 = other people

别人 usually means other people, others, or someone else, depending on context.

In this sentence, 关心别人 most naturally means:

• care about others
• be considerate toward other people

It does not specifically mean one single person here.

A few examples:

• 不要管别人。 = Don’t interfere with other people / mind others’ business.
• 替别人着想。 = Think for others.

So 别人 here is a broad, general object: other people.

Because 是 is not used before most verbs.

Here, 关心 is a verb, so the sentence is built directly:

• 他很关心别人 = He cares a lot about others.

Chinese uses 是 mainly to connect nouns:

• 他是老师。 = He is a teacher.

But not with most adjectives or verbs:

• 他很忙。 not 他是很忙
• 他关心别人。 not 他是关心别人

So 是 would be wrong here.

Chinese often describes a person through a body part, feature, or aspect of them. So 声音也总是不大 literally means:

• his voice is also always not loud

This sounds natural in Chinese and highlights his manner or temperament.

A more expanded version could be:

• 他的声音也总是不大。

The 的 is omitted because it is easy to understand whose voice it is from context.

You could also say:

• 他也总是说话不大声。
• 他说话的声音也总是不大。

But the original sentence is smooth and natural.

也 means also.

It connects the second characteristic to the first one:

1. 他平时很关心别人
2. 声音也总是不大

So the overall idea is:

• He usually cares a lot about others,
• and his voice is also always not loud.

The 也 shows that the second clause is another supporting detail about the same person.

总是 means always or consistently.

It is stronger than just often. It suggests a repeated, habitual pattern.

So:

• 声音总是不大 = his voice is always not loud / he is consistently soft-spoken

This helps show that speaking softly is part of his normal character, not just something happening once.

Compare:

• 常常 = often
• 总是 = always

This is due to a standard tone change rule.

不 is normally fourth tone: bù.
But when it comes before another fourth-tone syllable, it changes to second tone: bú.

Here:

• 大 is dà (fourth tone)
• so 不大 is pronounced bú dà

Examples:

• 不是 → bú shì
• 不对 → bú duì
• 不大 → bú dà

The writing stays 不, but the pronunciation changes.

Good question. 不大 literally means not big, but here it means not loud.

With 声音, 大 can mean:

• big in volume
• loud

So:

• 声音大 = the voice is loud
• 声音不大 = the voice is not loud

Why not 小?

• 声音小 is also possible and means the voice is quiet/soft
• 声音不大 is often a bit softer and less absolute in tone
• it can sound more polite, mild, or understated

So 不大 fits the gentle, restrained feeling of the sentence very well.

Yes, it is somewhat indirect, and that is part of the style.

Instead of bluntly saying:

• 他说话声音很小。
• 他总是轻声说话。

the sentence says:

• 声音也总是不大

This feels:

• milder
• more descriptive
• more character-focused

It suggests that he is soft-spoken by nature. Combined with 很关心别人, it paints a picture of someone gentle, considerate, and not forceful.

Yes. That is a very natural interpretation.

Taken together:

• 平时很关心别人
• 声音也总是不大

the sentence does more than list facts. It describes a personality:

• considerate
• thoughtful
• gentle
• soft-spoken

So while the literal meaning is about caring for others and having a quiet voice, the overall impression is that he has a mild and kind temperament.

Chinese often links related clauses with just a comma, especially when the relationship is already clear.

Here, the two clauses describe the same person:

• 他平时很关心别人
• 声音也总是不大

Because 也 already helps connect the second part, a comma is enough.

You could say:

• 他平时很关心别人，而且声音也总是不大。

But the original version is more natural and less heavy. Chinese often prefers this lighter style when describing someone’s traits.
