「will」と「be going to」の使い方

B1 英検2級 中級

will + base verb / be going to + base verb

説明

Use "be going to" for a plan or a future result that is clearly understood now. Use "will" for a decision made now, a promise, an offer, or a prediction based on what you think.

For example, "I'm going to study tonight." Here, "I'm" means "I am," and "going to" shows a plan already decided before speaking. "study" is the main verb, and "tonight" gives the time. Japanese often uses one future form, like "〜するつもりです" or "〜します," but English often chooses between "will" and "be going to."

例文

  • I'm going to study tonight. 今夜は勉強するつもりです。
  • She's going to visit her grandmother tomorrow. 彼女は明日、おばあさんを訪ねる予定です。
  • Are you going to stay here? ここにいるつもりですか。
  • We won't be late. 私たちは遅れません。
  • I think it will rain later. あとで雨が降ると思います。
  • The dark clouds mean it's going to rain soon. 黒い雲が出ているので、もうすぐ雨が降りそうです。

よくある間違い

Japanese learners often use "will" for a plan that was already decided.

Wrong: "I will meet my friend after work."

Right: "I'm going to meet my friend after work."

If the plan already exists, "be going to" is usually better.
