以下是一般现在时态的记忆口诀:
主语加s,动词原形不变;
主语不可数,动词不加s;
第三人称单数,动词加s;
特殊动词有所变,Do、Does不得跑。
简单来说就是,一般现在时态中,主语若是第三人称单数,动词要加上s后缀,而动词否定形式则要加上do not或does not。例如:
- I eat breakfast every day.
- You drink coffee in the morning.
- He eats lunch at noon.
- She works in the city.
- It rains a lot in the tropics.
- They drive to work together.
- The book costs $10.
- My cat sleeps all day.
这些句子中,第三人称单数主语he、she、it都需要在动词后面加上s,而其他主语则直接使用动词原形。
