例句

collocation: natural beauty / natural resources

  • unprocessed

    focuses on the absence of human alteration or refinement

  • artificial

    made by human skill, imitating something natural

常見錯誤

This sofa is made of natural leather.
This sofa is made of genuine leather.
💡Most leather is a processed material, so 'natural' sounds odd; 'genuine' fits better for real leather.

2. describing a quality, skill, or behaviour that someone is born with, rather than

2.形容詞B1
釋義

describing a quality, skill, or behaviour that someone is born with, rather than one they learn or develop through practice

例句

Young children have a natural curiosity about the world around them.

collocation: natural curiosity / natural instinct

Ramón has a natural talent for languages and speaks four fluently.

collocation: natural talent / natural ability

同義詞
  • innate

    formal synonym for qualities present from birth, common in academic contexts

  • inborn

    emphasises that the quality existed at birth

  • instinctive

    describes automatic, unlearned behaviours or reactions

反義詞
  • learned

    acquired through study or experience rather than present at birth

  • acquired

    gained over time, not part of one's original nature

用法筆記

Frequently used before nouns such as 'talent', 'ability', 'instinct', 'gift', 'curiosity', and 'charm' to describe fixed, inborn qualities rather than acquired ones. Distinguish from sense 1 (IN NATURE), where 'natural' modifies concrete objects or physical phenomena, not personal traits.

常見錯誤

She is natural at swimming.
She is a natural swimmer.' or 'She has a natural ability for swimming.
💡'Natural' as a modifier before a noun is the usual pattern for this sense.

3. describing someone who acts in a relaxed and real way, without pretending to be

3.形容詞B2
釋義

describing someone who acts in a relaxed and real way, without pretending to be different or trying to impress others

例句

Anna is very natural on stage and never seems nervous.

Christopher tried to act natural when his boss walked into the room.

collocation: act natural / look natural

同義詞
  • genuine

    emphasises sincerity; not pretending to have different feelings from one's real ones

  • unaffected

    suggests the person is not trying to impress or put on an act

  • spontaneous

    describes behaviour that arises naturally without planning or constraint

反義詞
  • fake

    behaving in a way that is not one's true self

  • forced

    suggesting effort or strain rather than relaxed ease

  • affected

    putting on a mannerism to impress others

用法筆記

Commonly used in the fixed phrase 'act natural' (stay calm and behave normally in a tense situation). When describing inanimate things like photographs, videos, or performances, it means 'not forced or posed.' Distinguish from sense 1 (IN NATURE), which applies to physical substances and phenomena, and sense 6 (NORMAL & EXPECTED), which applies to situations and reactions.

常見錯誤

She acted naturally during the job interview' (adverb needed).
She acted natural during the job interview.
💡After 'act,' the adjective 'natural' is idiomatic in informal English.

4. describes food or drink that is in its original, pure state, containing no artif

4.形容詞B1
釋義

describes food or drink that is in its original, pure state, containing no artificial chemicals, preservatives, or colourings

例句

Many families now choose natural foods that contain no preservatives.

collocation: natural food / natural ingredients

This yoghurt contains only natural ingredients and no added sugar.

同義詞
  • organic

    a certified farming standard requiring no synthetic pesticides or fertilisers

  • wholesome

    suggests food that is good for health because it is natural and unprocessed

  • unrefined

    describes foods like whole grains that have not been processed to remove natural components

反義詞
  • processed

    food that has been altered from its natural state, often with additives

  • artificial

    containing man-made chemical substances rather than natural ones

用法筆記

When applied to food, 'natural' is not a strictly regulated term in many countries, so products labelled 'natural' may still undergo some processing. It contrasts with 'organic,' which is a certified farming standard. Distinguish from sense 1 (IN NATURE), where 'natural' describes anything found in the physical world rather than only food.

常見錯誤

I only eat natural food, so I buy frozen dinners.
I buy fresh vegetables and natural ingredients, not processed frozen dinners.
💡'Natural food' refers to unprocessed or minimally processed products, not just any edible item.

5. describes a parent who conceived or gave birth to a child, as distinguished from

5.形容詞B2
釋義

describes a parent who conceived or gave birth to a child, as distinguished from a step-parent or adoptive parent

例句

Her natural mother gave birth at the age of seventeen.

collocation: natural mother / natural father / natural parent

Ishaan was adopted as a baby and later found his natural father.

同義詞
  • biological

    the more common and neutral modern term for a birth parent

  • birth

    used before 'parent/mother/father' to identify the parent involved in the child's birth

反義詞
  • adoptive

    describes a parent who legally takes on parental responsibility for a child not born to them

  • foster

    describes a temporary carer who is not a child's permanent legal parent

用法筆記

Primarily a legal or formal term. In everyday conversation, 'biological parent' or 'birth parent' is more common. The word 'natural' in this sense can sound dated to some speakers. Distinguish from sense 2 (INBORN ABILITY), which also refers to birth origins but applies to skills and traits, not family relationships.

常見錯誤

My natural parents raised me from birth.
My biological parents raised me from birth.
💡If someone was raised by their birth parents, there is no need to specify 'natural' or 'biological' at all.

6. happening in the usual way that most people would expect, without being unusual

6.形容詞A2
釋義

happening in the usual way that most people would expect, without being unusual or surprising

例句

It is natural to feel nervous before a job interview.

pattern: It is natural + to-infinitive

Making mistakes is a natural part of learning a new skill.

同義詞
  • normal

    the closest synonym; interchangeable in most contexts but slightly less formal

  • expected

    focuses on anticipation and social norms rather than inherent nature

  • understandable

    shifts emphasis from statistical normality to emotional reasonableness

反義詞
  • unusual

    not happening often or not typical

  • abnormal

    deviating from what is considered typical or standard

  • surprising

    causing a feeling of unexpectedness rather than natural acceptance

文法句型

it is natural + to-infinitive

it is natural + that-clause

用法筆記

Most common in the fixed constructions 'it is natural + to-infinitive' and 'it is natural + that-clause.' The intensifier 'only' (it is only natural that…) is a common collocation in this sense. Distinguish from sense 3 (RELAXED & GENUINE), which describes a person's manner or style, not the expected nature of an event or feeling.

常見錯誤

It's natural if she cries.
It's natural for her to cry.' or 'It's natural that she cries.
💡The common patterns are 'it is natural for [someone] to [verb]' or 'it is natural that [clause].'

7. describing a musical note that is played at its normal pitch, not raised by a sh

7.形容詞C1
釋義

describing a musical note that is played at its normal pitch, not raised by a sharp (♯) or lowered by a flat (♭)

例句

The piece has a B natural in the second bar instead of B flat.

pattern: [note name] + natural, e.g. 'B natural'

Élise played an F natural where the sheet music said F sharp.

反義詞
  • sharp

    a note raised by one semitone from its natural pitch

  • flat

    a note lowered by one semitone from its natural pitch

文法句型

[note name] + natural

用法筆記

Used after the name of a note (e.g., 'A natural,' 'E natural'). The written symbol is ♮. This sense belongs to musical terminology and is not used in general conversation. Distinguish from sense 2 (INBORN ABILITY) where 'natural' is a general adjective — here it is a post-positioned modifier in music notation.

natural — noun

natural — adverb
