TOPIK Practice – TOPIK I 어휘 [Vocabulary] 1–5 (1/12/2026) – temperature

정답: A. 더워서

How to solve: The sentence states that the air conditioner was turned on. Air conditioners are used when it's hot. Therefore, the blank should be filled with a word indicating 'because it's hot'. '더워서' (because it's hot) is the correct choice.

A — '더워서' means 'because it's hot'. This fits the context of turning on an air conditioner.

B — '추워서' means 'because it's cold'. This would lead to turning on a heater, not an air conditioner.

C — '따뜻해서' means 'because it's warm'. While pleasant, it doesn't typically necessitate turning on an air conditioner.

D — '시원해서' means 'because it's cool'. This would not be a reason to turn on an air conditioner; rather, one might turn it off or enjoy the coolness.

정답: B. 차가운

How to solve: The sentence contrasts winter, where warm coffee is preferred, with summer. In summer, people generally prefer cold drinks. Therefore, the blank should be filled with an adjective meaning 'cold' that can describe a drink.

A — '뜨거운' means 'hot'. This is suitable for winter, not summer drinks.

B — '차가운' means 'cold (to the touch/temperature)'. This is appropriate for describing a cold drink in summer.

C — '더운' means 'hot (weather/air)'. While summer weather is hot, '더운' is not typically used to describe a drink's temperature.

D — '추운' means 'cold (weather/feeling)'. Like '더운', it describes weather or a feeling, not the temperature of a drink.

정답: C. 온도

How to solve: The sentence states that 'the room is a bit cold' because something is 'too low'. The element that is typically 'low' and causes a feeling of coldness in a room is its temperature. '온도' (temperature) is the appropriate word.

A — '날씨' means 'weather'. Weather refers to the atmospheric conditions outside, not inside a room.

B — '습도' means 'humidity'. While humidity can affect comfort, it's not typically described as 'low' in a way that directly makes a room feel 'cold' in the same sense as temperature.

C — '온도' means 'temperature'. If the room's temperature is low, it makes the room feel cold. This fits perfectly.

D — '바람' means 'wind'. While wind can make a room feel cold if it enters, it's not an inherent property of the room itself that is 'low'.

정답: B. 영하

How to solve: The sentence indicates that the weather is 'very cold'. When referring to degrees and very cold temperatures, 'below zero' is typically used. '영하' means 'below zero'.

A — '영상' means 'above zero'. This would imply warmer weather, contradicting '많이 추워요' (very cold).

B — '영하' means 'below zero'. This is consistent with 'very cold' weather and a temperature like 5 degrees (meaning -5 degrees Celsius).

C — '보통' means 'usually' or 'normal'. It's an adverb and doesn't fit into the context of describing a temperature value.

D — '높다' means 'to be high'. This describes a characteristic and doesn't fit before a degree value in this context.

정답: B. 더위

How to solve: The sentence states 'in summer, it's hard because I suffer a lot from ______'. The word that fits this context and is commonly associated with difficulty in summer is 'heat'. '더위' means 'heat (as a noun, the state of being hot)'. The idiom '더위를 타다' means 'to be sensitive to heat' or 'to suffer from heat'.

A — '눈' means 'snow' or 'eye'. Snow is not relevant to summer heat.

B — '더위' means 'heat' (noun). The phrase '더위를 타다' is a common idiom meaning to be sensitive to or suffer from the heat, which is very relevant to summer.

C — '비' means 'rain'. While it rains in summer, it's not what primarily makes summer hard in terms of 'suffering from' in this context.

D — '바람' means 'wind'. Wind usually brings relief in summer, not hardship.
