N2 Vocabulary · Test 66

専念 (せんねん) means 'to devote oneself to / to concentrate fully on (something).' 勉強に専念する is a standard expression meaning 'to focus entirely on studying.' The sentence says the person quit their part-time job to concentrate on studying for an approaching exam.

• 1特定 (とくてい) means 'to specify/identify.' 勉強に特定する is not a meaningful collocation.
• 2統一 (とういつ) means 'to unify/standardize.' This is used for making things uniform (e.g., 規格を統一する), not for focusing on something.
• 4注目 (ちゅうもく) means 'to pay attention to / to focus on (as an object of interest).' While 勉強に注目する could mean 'to turn one's attention to studying,' it doesn't convey the sense of devoting oneself entirely. 勉強に注目することにした sounds like 'decided to pay attention to studying,' which is weaker than the intended meaning of concentrating fully.

• 専念せんねん — to devote oneself to, concentrate fully on
• 特定とくてい — to specify, identify
• 統一とういつ — to unify, standardize
• 注目ちゅうもく — to pay attention to, to take notice of

The correct option is 4. 格好 (かっこう) refers to one's appearance, especially their attire, outfit, or getup. The phrase ちゃんとした格好で行く (to go in proper attire) is a very common collocation meaning to dress appropriately for an occasion. The speaker is wondering if they should dress up properly for the graduation party.

• 1様子 (ようす) means 'state,' 'condition,' or 'situation' (e.g., the state of the weather, or someone's mood). You cannot use 様子で行く to mean dressing up for an event.
• 2容姿 (ようし) refers to a person's physical appearance, particularly their facial features or figure. Since you cannot change your physical features just to go to a party, ちゃんとした容姿で行ったほうがいい is unnatural.
• 3外見 (がいけん) means 'outward appearance' and is often used in contrast to inner qualities (e.g., 外見より中身 'substance over outward appearance'). While it relates to appearance, it is not used to describe dressing appropriately for a specific occasion like 格好 is.

• 格好かっこう — appearance, figure, attire, getup
• 様子ようす — state, condition, situation
• 容姿ようし — appearance (especially facial features/figure)
• 外見がいけん — outward appearance
• ちゃんとした — proper, decent, appropriate

夢中に (むちゅうに) means 'absorbed in / engrossed in.' The pattern 〜に夢中になる means 'to become absorbed in something.' The sentence says 'I had become so absorbed in reading that I forgot the time I promised to meet my friend.' 読書に夢中になる is a natural, common expression.

• 1好調に (こうちょうに) means 'prosperously / going well.' This describes a favorable condition or trend (e.g., business is going well), not a state of deep concentration.
• 3頑固に (がんこに) means 'stubbornly.' This describes someone refusing to change their opinion or attitude, not being absorbed in an activity.
• 4強引に (ごういんに) means 'forcibly / in a pushy manner.' This describes doing something by force or coercion, not losing track of time while reading.

• 夢中むちゅう — absorbed in, engrossed in (〜に夢中になる)
• 好調こうちょう — prosperous, going well
• 頑固がんこ — stubborn, obstinate
• 強引ごういん — forcible, pushy, high-handed

The correct option is 1. 「ごろごろ」 is an onomatopoeic word that describes idling away time or lying around lazily, very commonly used with the phrase 「ベッドでごろごろする」 (to lie around in bed doing nothing). In this context, the speaker woke up early and stayed in bed for a while, making this the perfect fit.

• 2「ぶらぶら」 means to stroll aimlessly, wander around, or to dangle/swing loosely. It is typically used for walking around outside (e.g., 街をぶらぶらする) or something hanging, not for lying in bed.
• 3「ゆらゆら」 means to sway or swing gently back and forth, like a boat on the water or a candle flame. It does not describe a person's action of resting in bed.
• 4「うろうろ」 means to pace restlessly, wander about in confusion, or be flustered. It implies anxious or aimless movement, which contradicts the relaxed context of staying in bed early in the morning.

• ごろごろ — idling, lying around lazily (often in bed)
• ぶらぶら — strolling aimlessly, dangling
• ゆらゆら — swaying gently back and forth
• うろうろ — pacing restlessly, wandering about in confusion
