Question 1

Kenji is writing a diary entry. He writes: 「きのう、としょかんで べんきょう 。あした、また いきます。」

Which verb form correctly completes Kenji's sentence about what he did yesterday?

  1. します (shimasu) — present/future tense, indicating a habitual or upcoming action at the library
  2. しました (shimashita) — past tense, indicating the studying action was completed yesterday (correct answer)
  3. しています (shite imasu) — present progressive, indicating studying is currently ongoing right now
  4. しません (shimasen) — present negative, indicating he does not study at the library
Explanation: When reading a Japanese diary entry or sentence, always pay close attention to time words — they tell you exactly which verb tense belongs in the blank. Here, きのう (kinou) means "yesterday," which signals that the action happened in the past and is now completed. Japanese uses the ～ました (mashita) ending to express past tense for polite speech. The verb する (suru, "to do") becomes しました (shimashita) in the polite past form, making B the correct choice. The full sentence reads: "Yesterday, I studied at the library" — a completed action, perfectly matching きのう. Looking at the wrong answers: A) します (shimasu) is the present/future tense, used for habitual actions or future plans (which is actually why the second sentence uses いきます — "I will go again tomorrow"). Using します here would clash with きのう. C) しています (shite imasu) is the present progressive, meaning something is currently happening right now — Kenji is writing his diary, not studying at the library at this moment, so this tense is out of place. D) しません (shimasen) is the present negative form, meaning "does not study," which completely contradicts the context — Kenji clearly did study, which is why he's writing about it. A useful study tip: scan for time expressions first (きのう = yesterday → past tense; あした = tomorrow → future/present tense; いま = now → progressive). These words are your fastest clue for choosing the correct verb form in Japanese.

Question 2

A student reads this sentence: 「まいにち あさ ろくじに おきます。でも、きょうは しちじに おきました。」

What is the most accurate interpretation of the relationship between the two verb forms used in this passage?

  1. Both verbs describe future intentions — the speaker plans to wake up at 6 AM every day and also at 7 AM today
  2. The first verb describes a habitual present routine, while the second describes a specific past event that deviated from that routine today (correct answer)
  3. Both verbs describe completed past events — the speaker used to wake up at 6 AM and also woke up at 7 AM in the past
  4. The first verb describes an ongoing present action and the second describes a future plan that will occur later today
Explanation: When reading Japanese sentences, pay close attention to verb endings — they carry critical information about tense and aspect that shapes the entire meaning of a sentence. In this passage, 「おきます」uses the dictionary/present-habitual form (non-past), which in Japanese expresses either a current routine or a future intention depending on context. Here, 「まいにち あさ ろくじに」("every morning at 6 AM") makes it clearly a habitual routine — something the speaker does regularly. The second verb, 「おきました」, ends in 「ました」, which is the polite past tense form, indicating a completed action. Combined with 「きょうは」("as for today") and 「でも」("but/however"), the sentence explicitly signals a contrast: the usual habit versus what actually happened today. This confirms that B is correct — the first verb describes an ongoing daily habit, and the second describes a specific past event that broke from that routine. A is wrong because neither verb is expressing future intention here — the context clues (「まいにち」and 「きょうは でも」) anchor both statements to habitual present and completed past, not future plans. C is wrong because it misreads 「おきます」as past tense — the non-past form does not carry past meaning, and interpreting both as past events ignores the habitual marker 「まいにち」. D is wrong because 「おきます」describes a routine, not an ongoing action happening right now, and 「おきました」is past tense, not a future plan. A helpful tip: always look for time expressions like 「まいにち」, 「きょう」, or 「でも」alongside verb endings — they work together to reveal tense and context.

Question 3

Yuki says: 「いま、おふろに はいっています。でんわに でられません。」

Why does Yuki use 「はいっています」 rather than 「はいります」 in this context?

  1. 「はいっています」 expresses a completed past action, meaning Yuki already finished her bath before the call came
  2. 「はいっています」 expresses a habitual routine, meaning Yuki takes baths regularly and never answers the phone during them
  3. 「はいっています」 expresses a future intention, meaning Yuki is planning to take a bath and cannot answer the phone then
  4. 「はいっています」 expresses an action currently in progress at the time of speaking, consistent with the time word 「いま」 (now) (correct answer)
Explanation: When you see a verb followed by 「ています」, your first instinct should be to ask: what kind of verb is this, and what does it tell us about timing? This question tests your understanding of how 「ています」 interacts with action verbs to describe ongoing states. 「はいる」 (to enter/to get in) is an action verb. When you attach 「ています」 to action verbs, it typically describes an action currently in progress — similar to the English present progressive "is doing." Here, Yuki is saying right now, she is in the middle of bathing, which is why she cannot come to the phone. The time word 「いま」 (now) is your strongest clue — it anchors the action firmly in the present moment, confirming that D is correct. Choice A is a common trap. While 「ています」 can sometimes describe a resultant state (e.g., 「結婚しています」 means "is married," implying a completed event), 「おふろにはいっています」 describes an ongoing process, not a finished one. If Yuki had already finished, she could answer the phone. Choice B mistakes 「ています」 for a habitual expression — habits are typically conveyed with plain form verbs plus frequency words (e.g., 「毎日はいります」). Choice C confuses 「ています」 with future intention, which would more naturally use 「はいります」 or 「はいるつもりです」. Study tip: Train yourself to spot 「いま」 + 「ています」 as a reliable signal for currently in progress. When you see them together, think present progressive first before considering other meanings of 「ています」.

Question 4

Read the following conversation: A: 「もう しゅくだいを しましたか。」 B: 「いいえ、まだ 。」

Which option correctly completes B's response using 「まだ」 (still/not yet) in a grammatically and contextually appropriate way?

  1. 「していません」— present negative, meaning 'I have not done it (yet),' naturally paired with 「まだ」 to express incompletion (correct answer)
  2. 「しませんでした」— past negative, meaning 'I did not do it,' typically used when reporting a past decision rather than an ongoing incomplete state
  3. 「しています」— present progressive positive, meaning 'I am doing it now,' which contradicts the negative response initiated by 「いいえ」
  4. 「しました」— past affirmative, meaning 'I did it,' which directly contradicts the negative opener 「いいえ」 and the word 「まだ」
Explanation: When you see 「まだ」 paired with 「いいえ」 in Japanese, your first instinct should be to think about how incompletion is expressed. 「まだ」 means "still" or "not yet," and it signals that an action or state is ongoing in its unfinished form — not simply that something didn't happen in the past. This is why A (「していません」) is correct. The present negative form 「していません」 expresses that the homework has not been done and remains undone, which pairs naturally with 「まだ」. The full sentence 「まだ していません」 translates smoothly as "I haven't done it yet," perfectly answering A's question about whether the homework is complete. B (「しませんでした」) is past negative, meaning "I did not do it." While grammatically a negative form, it implies a completed decision in the past rather than an ongoing incomplete state. 「まだ」 requires a sense of continuation, so the past tense clashes with its meaning. C (「しています」) is present progressive and positive, meaning "I am doing it now." This directly contradicts the 「いいえ」 that opens B's response — you cannot say "no" and then confirm an ongoing action. D (「しました」) is past affirmative, meaning "I did it." This is doubly wrong: it contradicts both 「いいえ」 and 「まだ」, since it would mean the task was completed. A useful pattern to remember: まだ + ていません is the standard formula for "not yet" in Japanese. Whenever you see 「まだ」 in a negative response, look for the 「〜ていません」 ending.

Question 5

Hana writes: 「ちいさいとき、まいにち うみで およいでいました。でも、いまは もう およぎません。」

What do the contrasting verb forms in Hana's sentences reveal about the temporal structure of her statement?

  1. Both verbs are in the same tense — they both describe past habitual actions, and the contrast is only about location, not time
  2. The first verb 「およいでいました」 describes a habitual ongoing past activity during childhood, while 「およぎません」 describes the present situation where that activity no longer occurs (correct answer)
  3. The first verb 「およいでいました」 describes a single completed past event, while 「およぎません」 describes a future plan to stop swimming permanently
  4. The first verb 「およいでいました」 is present progressive tense describing swimming happening right now in the past, and 「およぎません」 is a polite refusal to swim in the future
Explanation: When you see contrasting verb forms in Japanese, your first instinct should be to analyze the tense and aspect of each verb separately before looking at how they interact. Japanese verb endings carry rich temporal information, so unpacking them is the key to understanding what a speaker is communicating about time. Here, 「およいでいました」 is built from the te-form of 「およぐ」 (to swim) combined with 「いる」 in past tense — forming the past progressive/habitual pattern 「〜ていました」. Paired with 「ちいさいとき」 (when I was little) and 「まいにち」 (every day), this clearly describes a repeated, habitual activity in the past. Then 「およぎません」 is the plain negative non-past form, meaning "do not swim" — describing the current, present situation. The word 「もう」 (no longer/anymore) reinforces that this is a present-tense contrast with the past habit. Answer B captures this perfectly: childhood habitual activity versus present-day cessation. Answer A is wrong because the two verbs are not the same tense — 「〜ていました」 is past, while 「〜ません」 is present. The contrast is explicitly temporal, not merely locational. Answer C misreads 「およいでいました」 as a single completed event (which would be 「およぎました」, simple past), and incorrectly calls 「およぎません」 a future plan — it describes present habit, not future intention. Answer D confuses the function of 「〜ていました」; it doesn't mean "present progressive set in the past" like a narrative flashback, and 「およぎません」 is not a refusal — it's a factual present-tense statement. Study tip: Always decompose Japanese verb forms piece by piece — stem, te-form, auxiliary, and politeness ending — and note any time words nearby. They almost always confirm the tense the verb endings suggest.

Question 6

Taro makes the following statement: 「きょうの ごご、ともだちと えいがを みます。でも、きのうの よる、チケットを かいました。」

A student argues that Taro should have used 「みました」 in the first sentence because he bought the tickets yesterday. What is the flaw in this argument?

  1. The student is correct — since the tickets were purchased in the past, the movie-watching event is also considered past and requires past tense
  2. The student is correct that the tense should match, but the error is that 「かいました」 in the second sentence should actually be changed to 「かいます」 to match the future event
  3. The student is wrong — verb tense in Japanese is determined by when the action itself occurs, not by related past actions; 「きょうの ごご」 (this afternoon) is a future time, so non-past tense 「みます」 is correct (correct answer)
  4. The student is wrong, but only because 「みます」 can optionally mean past tense in casual speech, making both forms acceptable in this sentence
Explanation: When you see a question about verb tense in Japanese, the key principle to anchor yourself to is this: Japanese verb tense is determined by when the action itself takes place, not by the circumstances surrounding it. In Taro's statement, 「きょうの ごご」 (this afternoon) clearly places the movie-watching event in the future relative to when he is speaking. Because the action of watching — 「みる」 — hasn't happened yet, the non-past form 「みます」 is exactly correct. The fact that he already bought the tickets yesterday is simply background information about a separate action. Those two events exist on their own points in time and are conjugated independently. This is why C is correct: tense follows when the action occurs, full stop. A reflects a common logical trap — assuming that because a related event (buying tickets) happened in the past, the main event must also be treated as past. Japanese doesn't work this way. Each verb describes its own action on its own timeline. B compounds the error in A by suggesting that 「かいました」 should be changed to match the future event. This reverses the logic entirely — Taro genuinely did buy the tickets last night, so 「かいました」 (past tense) is perfectly appropriate for that action. D is simply fabricated. 「みます」 does not carry an optional past-tense meaning in casual speech. Non-past forms cover present habits and future events — nothing more. A useful study tip: whenever you see a time expression like 「きのう」, 「きょう」, or 「あした」, let that word guide your tense choice, not surrounding context.

Question 7

A student sees two sentences: ① 「さんねんまえ、にほんに すんでいました。」 ② 「いま、にほんに すんでいます。」

A classmate claims both sentences mean essentially the same thing because both use the -te iru form. What is the critical error in the classmate's reasoning?

  1. The classmate ignores that the -te iru form changes meaning entirely when combined with different time expressions — sentence ① describes a past ongoing state using 「さんねんまえ」, while sentence ② describes a current ongoing state using 「いま」 (correct answer)
  2. The classmate is correct — both sentences describe an ongoing state, so they have the same meaning regardless of the time expressions used
  3. The classmate is almost right, but the error is that sentence ① uses past tense while sentence ② uses present tense, which means the -te iru form is grammatically wrong in sentence ①
  4. The classmate is correct that the -te iru form has the same meaning in both, but is wrong that the sentences are identical because the locations mentioned are different
Explanation: When you see a question involving 〜ています (te iru form), don't just look at the verb ending — always check the time expression surrounding it. The te iru form is flexible: it can describe an ongoing state in the present or the past, depending on the temporal context provided by words like 「いま」(now) or 「さんねんまえ」(three years ago). This is exactly why A is correct. Sentence ① uses 「さんねんまえ」to anchor the ongoing state in the past — "Three years ago, I was living in Japan." Sentence ② uses 「いま」to anchor it in the present — "Right now, I am living in Japan." The te iru form itself stays the same grammatically, but the time expression completely shifts the meaning. The classmate's error is treating the verb form in isolation while ignoring the words that give it temporal context. B is wrong because it assumes the time expressions are irrelevant — they are, in fact, the entire reason the sentences differ in meaning. C introduces a false claim: the te iru form in sentence ① is not grammatically wrong. Japanese allows te iru to express past ongoing states naturally when paired with a past time marker. There is no error in its usage. D is wrong because it misidentifies location as the source of difference — both sentences actually mention the same location (にほん/Japan), so this reasoning is factually off and misses the real issue entirely. Your study tip: always read te iru sentences with their time expressions. The form doesn't change — the context does all the work.

Question 8

Which sentence correctly uses a time expression with a verb form to describe a future plan in natural Japanese?

  1. 「らいしゅう、ともだちに あいました。」— uses past tense with the future time word 'next week'
  2. 「きのう、えいがを みます。」— uses present/future tense with the past time word 'yesterday'
  3. 「あした、にほんごを べんきょうします。」— uses present/future tense with the future time word 'tomorrow' (correct answer)
  4. 「せんしゅう、かいものを します。」— uses present/future tense with the past time word 'last week'
Explanation: When describing plans or events in Japanese, the time expression and verb tense must logically match. Japanese uses the present/future form (dictionary form or ます-form) for future events, and the past form (ました-form) for completed events. A mismatch between the time word and verb form makes a sentence unnatural or grammatically incorrect. Choice C, 「あした、にほんごを べんきょうします。」is correct because あした (tomorrow) is a future time word, and べんきょうします is the present/future tense ます-form. These match perfectly, and the sentence naturally means "Tomorrow, I will study Japanese." This is exactly how you express a future plan in Japanese. Choice A is wrong because らいしゅう (next week) points to the future, but あいました is past tense. You cannot say you "met" someone next week — the tenses contradict each other. Choice B makes the opposite error: きのう (yesterday) is a past time word, but みます is present/future tense. Saying you "will watch" a movie yesterday is logically impossible. Choice D pairs せんしゅう (last week) — another past time word — with します, the present/future form. Like B, this creates an illogical contradiction between when the event happened and the verb form used. A useful study tip: always scan both the time word and the verb ending in a sentence. Ask yourself, "Is this time word pointing to the past or future?" Then confirm the verb ending matches. This matching strategy will help you quickly eliminate incorrect options on tense-based questions.

Question 9

Which of the following sentences contains a grammatical error in the pairing of a time expression and verb form?

  1. 「おととい、ゆうごはんを たべました。」— 'the day before yesterday I ate dinner'
  2. 「らいねん、だいがくに はいります。」— 'next year I will enter university'
  3. 「まいあさ、こーひーを のみます。」— 'every morning I drink coffee'
  4. 「あさって、ともだちに あいました。」— 'the day after tomorrow I met my friend' (correct answer)
Explanation: In Japanese, matching your time expression to the correct verb tense is essential. Past-tense time words (like おととい, "the day before yesterday") pair with ～ました forms, while future or habitual time words pair with ～ます forms. When you see a question like this, scan each sentence for whether the time word points to the past, present/future, or habitual — then check if the verb form agrees. Option D is the problematic sentence: 「あさって、ともだちに あいました。」 Here, あさって means "the day after tomorrow" — a future time expression — but あいました is the past tense of あう ("to meet"). You cannot have already met someone the day after tomorrow, so the tense is logically and grammatically contradicted. The correct form should be あいます, aligning with the future context. The other options are all grammatically sound. Option A uses おととい ("the day before yesterday") with たべました (past tense) — a perfect match, since that event already happened. Option B pairs らいねん ("next year") with はいります (non-past/future form), correctly expressing a future intention. Option C uses まいあさ ("every morning") with のみます, which appropriately uses the non-past form to describe a habitual action — a very common and correct pattern in Japanese. A useful study tip: create a mental checklist of time words sorted by category — past (きのう、おととい), future (あした、あさって、らいねん), and habitual (まいにち、まいあさ) — and always verify the verb ending matches. Mismatched time-and-tense pairings like D are a classic trap on Japanese grammar questions.
