✏️ TOEIC文法:to do と doing の使い分け方をマスターしよう
以下はTOEICで繰り返し出てくる動詞です。
この動詞の後には **doing(〜すること)**が来るのか、**to do(〜すること)**が来るのか。
ただそれだけを覚えてください。
✅ 【doing(〜すること)】が後に来る動詞(動詞+ing)
この動詞の後には 必ず -ing形 を使います。
avoid doing → We avoided taking unnecessary risks.
enjoy doing → He enjoys working with numbers.
consider doing → They are considering expanding to Europe.
finish doing → I just finished reading the report.
suggest doing → She suggested meeting next week.
⚠️ TOEICの罠:「suggest to meet」は不正解。
to を入れないで!
✅ 【to do】が後に来る動詞(動詞+to動詞)
このパターンの動詞の後は 必ず to + 動詞の原形。
decide to do → He decided to cancel the trip.
expect to do → We expect to finish by Friday.
hope to do → I hope to join the team soon.
offer to do → She offered to help with the project.
plan to do → They plan to expand next year.
want to do → I want to improve my score.
⚠️「planning expanding」や「hoping joining」などは全部バツ!
✅ 【人 + to do】が必要な動詞(動詞+人+to動詞)
このパターンの動詞は、人(目的語)を挟んでから to + 動詞。
ask someone to do → She asked him to wait.
tell someone to do → They told me to call back.
remind someone to do → I reminded her to submit the form.
advise someone to do → He advised me to apply early.
encourage someone to do → They encouraged us to try again.
⚠️「They encouraged to try again」みたいに、人が抜けてる文は不正解。
⚠️ 【意味が変わる】doing も to do も両方使えるけど注意
このタイプの動詞はどちらも文法的に正しいけど、意味が変わります。
stop doing → 行動をやめる
She stopped smoking.(彼女は喫煙をやめた)stop to do → 別の行動のために一度止まる
She stopped to smoke.(彼女はタバコを吸うために立ち止まった)
remember doing → 過去にやったことを覚えている
I remember meeting him last year.remember to do → 忘れずにやる
Remember to lock the door.
try doing → 試しにやってみる
Try restarting the app.try to do → 頑張ってやる
Try to finish today.
⚠️ TOEICの問題では意味の違いをよく狙ってきます!
✅ TOEIC頻出:前置詞の後は「doing」だけ!
前置詞(at, in, about, for, without など)の後は 必ず -ing形。
She’s good at negotiating.
They succeeded in winning the bid.
Before leaving, please lock the door.
⚠️「She’s good at to negotiate」はNG!
