同義詞

文法句型

how + do/does/did + subject + verb

how + modal + subject + verb

how + to-infinitive

用法筆記

In indirect (embedded) questions, the word order is subject + verb, not verb + subject. Compare: How did she escape? (direct) → I wonder how she escaped. (indirect)

常見錯誤

Can you show me how I can make sushi?' (correct but wordy)
Can you show me how to make sushi?
💡Use the shorter how + to-infinitive pattern when the subject is the same.
I don't know how does this work.
I don't know how this works.
💡In embedded questions, keep subject-verb order.

2.副詞A2
釋義

used after a specific event or situation to ask for an update about someone's health, mood, or wellbeing

例句

How is your father after his knee surgery?

how + be + subject + after [event]

I called the clinic to ask how the patient was feeling this morning.

how + subject + be + feeling

同義詞
  • in what state

    more formal; used in written medical or formal contexts

文法句型

how + be + subject

how + be + subject + feeling/doing

用法筆記

Unlike sense 6 (WELL-BEING), this sense asks about a specific condition after a particular event — an illness, exam, move, or other change — and expects a detailed answer rather than a short social reply.

常見錯誤

How is your father does after the operation?
How is your father after the operation?
💡Do not add do/does when be is the main verb.

3.副詞A1
釋義

used to ask for an evaluation of an event, activity, or experience that has happened or is happening

例句

How was your trip to the Grand Canyon?

how + be for asking about an experience

How did Yael's first cooking class at the community centre go?

how + did + subject + go

同義詞

文法句型

how + be + subject

how + did + subject + verb

用法筆記

Very common after events that have just finished. The verb is usually be, go, or turn out. Expects an evaluative answer (good/bad/fun/boring).

常見錯誤

How was your weekend?' 'I was fine.' (mixing up experience vs condition)
It was great, thanks.
💡This sense asks about the experience, not your physical state.

4. used at the start of an exclamation to express strong feelings such as surprise,

4.副詞B1
釋義

used at the start of an exclamation to express strong feelings such as surprise, pleasure, or admiration about a quality or action

例句

How beautiful the mountains looked in the morning light!

how + adjective + subject + verb exclamation

How quickly the children grew up and started school!

how + adverb + subject + verb exclamation

同義詞
  • what (a/an)

    used with nouns: What a beautiful mountain!; how is used with adjectives/adverbs

文法句型

how + adjective + subject + verb

how + adverb + subject + verb

用法筆記

Follows the fixed pattern how + adjective/adverb + subject + verb. Do not use do/does/did — the subject comes directly after the adjective or adverb. Compare: How quickly she runs! (exclamation) vs How quickly does she run? (question).

常見錯誤

How she runs quickly!' (wrong word order)
How quickly she runs!
💡The adjective/adverb must come right after how, before the subject.

5. used in rhetorical questions to express strong surprise, shock, or disapproval a

5.副詞B2
釋義

used in rhetorical questions to express strong surprise, shock, or disapproval at something that seems unreasonable or unacceptable

例句

How could Beatrix leave without saying goodbye to anyone?

how + could + subject + verb for disapproval

How can anyone spend that much money on a pair of shoes?

同義詞
  • I can't believe

    less direct; states the speaker's reaction rather than questioning

文法句型

how + modal/could + subject + verb

how + can/could + subject + be + adjective

用法筆記

These are rhetorical questions — they do not expect an answer. The speaker's real purpose is to express a strong feeling. The stronger versions use how dare (anger) or how could (shock/disappointment).

常見錯誤

How could he does that?
How could he do that?
💡After a modal verb, use the base form of the verb, not the -s form.

6. used as part of a greeting formula to ask in a general way how someone is, witho

6.副詞A1
釋義

used as part of a greeting formula to ask in a general way how someone is, without expecting a detailed answer

例句

Saira greeted me with a warm smile and said, "How are you?"

standard greeting: how are you

How are you doing this fine morning, Mr. Chen?

how + be + subject + doing

同義詞

文法句型

how + be + subject

how + be + subject + doing

how are things/life

用法筆記

Commonly used as an opening greeting. The expected reply is usually short and positive (Fine, thanks / Good, you?), even when things are not perfect. This is a social routine, unlike sense 2 (CONDITION) which asks for a specific update after an event.

常見錯誤

How are you?' 'I am not very good, my back hurts.' (over-sharing in casual greeting)
I'm fine, thanks. And you?
💡In most casual greetings, a short positive reply is the social norm, even if you are not feeling 100%.

7. a set phrase used upon being introduced to someone in a formal context

7.副詞B1
釋義

a set phrase used upon being introduced to someone in a formal context

例句

How do you do? My name is Christopher, and I work in the finance department.

How do you do? followed by self-introduction

When Adaeze met her boss's husband, he said 'How do you do?' and shook hands.

How do you do? during introductions

文法句型

How do you do?

用法筆記

This fixed phrase expects the same expression in reply: 'How do you do?' It is not a genuine question about the other person's state. Almost exclusively British English and quickly becoming old-fashioned.

常見錯誤

How do you do? I'm fine, thank you.
How do you do?' replied with the same phrase.
💡'How do you do?' is a formal greeting, not a question about health, so the correct reply is the same phrase.

8. used to request that a person elaborate on information they have already mention

8.副詞A2
釋義

used to request that a person elaborate on information they have already mentioned when you need more detail

例句

You said the project is behind schedule — how? Did the team run into unexpected problems?

standalone how? after a statement

Élise asked her professor, 'How exactly does that theory apply to real-world situations?'

how + exactly + clause

同義詞
  • in what way

    more formal and explicit than standalone 'how?'

  • why

    asks for a reason rather than a method or mechanism

文法句型

how? (standalone)

how + clause?

用法筆記

Frequently used alone as a one-word question ('How?') after the speaker has made a claim. Can also introduce a full clause asking for the mechanism or reasoning behind a statement.

常見錯誤

How? You are saying the meeting is cancelled.' (no comma or context)
The meeting is cancelled.' 'How? I thought everyone had confirmed.
💡'How?' as a standalone question needs a preceding statement to refer back to.

9. used to check whether the person you are speaking to is satisfied with something

9.副詞B1
釋義

used to check whether the person you are speaking to is satisfied with something you have offered, prepared, or arranged for them

例句

How is your room, sir? Would you like extra pillows or a different view?

how + is + noun? — service context

Heloísa held up the dress and asked, 'How does this look on me?'

同義詞

文法句型

how + is/does/are + noun phrase?

用法筆記

Subject is typically a concrete thing you have provided (a room, a meal, a piece of work). The question expects a positive or negative evaluation, not a simple yes or no.

常見錯誤

How does the food? It is good.' (missing verb)
How does the food taste?' or 'How is the food?
💡'How' needs a verb like 'is', 'looks', or 'tastes' after the subject.

10. used as a short response to express that you share the same opinion, feeling, or

10.副詞B1
釋義

used as a short response to express that you share the same opinion, feeling, or experience as the person who just spoke

例句

Adaeze complained about the traffic. Her colleague said, 'How true! I was stuck too.'

how true — agreeing with a statement

'The kids have grown so much.' 'How they have!' said Aunt Mei with a smile.

how + subject + verb — emphatic agreement

同義詞
  • I agree

    more direct and less emotional than 'How true!'

  • exactly

    similar emphatic agreement but used as a single word

文法句型

how + adjective!

how + subject + verb!

用法筆記

Common patterns are 'How true!' (for factual agreement), 'How + subject + verb!' (for emphatic confirmation), and 'How + adjective!' (for emotional agreement). Distinguish from adverb sense 4 which uses 'how' for general emphasis without agreeing with another speaker.

常見錯誤

How true! I have never thought about it before.' (contradicts agreement)
How true! That is exactly what I was thinking.
💡'How true' signals that you already agree; it does not introduce a new or opposite idea.

11. used at the start of questions before an adjective, adverb, or words such as muc

11.副詞A1
釋義

used at the start of questions before an adjective, adverb, or words such as much, many, old, far, and long, in order to learn the size, number, age, distance, or cost of something

例句

How much does this jacket cost? I really like the colour and the style.

how + much — asking price

Cyrus asked the receptionist how long the train ride from Taipei to Kaohsiung takes.

how + long — asking duration

同義詞

文法句型

how + adjective/adverb?

how + much/many/long/far/old + noun/verb?

用法筆記

This is the most basic and frequent pattern for using 'how'. The adjective or adverb always comes immediately after 'how': 'how big', 'how quickly', 'how often'. In indirect questions, word order changes to subject + verb: 'She asked how old he was.'

常見錯誤

How old is he?' 'He has thirty years old.
How old is he?' 'He is thirty years old.
💡In English, 'old' goes with 'be', not 'have'. Taiwanese learners sometimes use 'have' by transfer from Chinese 幾歲.

how — conjunction

how — noun
