often 后面用 do 还是 does
“often” 是频度副词,本身不决定后面用 “do” 还是 “does”,关
键取决于句子的主语和时态(通常用于一般现在时)。具体规则如下:
1. 当主语是第一人称(I/we)、第二人称(you)或复数名词 /
代词时,用 do
I often do my homework in the evening.(我经常在晚上做作业。)
You often do sports on weekends.(你 / 你们经常在周末做运
动。)
They often do housework together.(他们经常一起做家务。)
Dogs often do funny things.(狗经常做些有趣的事。)
2. 当主语是第三人称单数(he/she/it 或单数名词 / 代词) 时,
用 does
He often does his own cooking.(他经常自己做饭。)
She often does yoga in the morning.(她经常在早上做瑜伽。)
The cat often does this trick.(这只猫经常玩这个把戏。)
My father often does the gardening.(我爸爸经常做园艺。)
总结
“do” 和 “does” 的选择由主语的人称和数决定(一般现在时中),
与 “often” 无关。第三人称单数用 “does”,其他情况用 “do”。
