技高高一適用 · A2–B1字彙 · 原形動詞不能自己當謂語,只能出現在特定情境,尤其是 be
❌ 學生常錯:He will is happy. / To is happy / Don't is late.
✔ 正確:He will be happy. / To be happy / Don't be late.
觀念:平常當謂語,be要看主詞變 am / is / are / was / were。但出現在6大情境中,永遠只用原形 be,三單也不加s!
| 情況 | I | He / She / Ken | They | 6大情境中 |
|---|---|---|---|---|
| 現在 | am | is | are | 永遠 be will be / to be Don't be / better be |
| 過去 | was | was | were | |
| 三單現在 | He is / He plays(要變形) | |||
點擊英文單字可查詞+發音。例:be careful
Ken will be late. (Ken會遲到。)
They can fix the computer. (他們會修電腦。)
❌ He will is busy. ✔ He will be busy. |三單也不加s:He can play,不是plays。
子點:do/does/did問句否定也是屬於這個情境:Does Ken play basketball? / He does not watch TV.

提醒:make/have + be很少見,多用形容詞:make me happy。看到be多半是let it be。
