英文過去分詞?快!幫幫忙!

1. visited (過去式), visited (過去分詞)
2. watched (過去式), watched (過去分詞)
3. swam (過去式), swum (過去分詞)
4. cycled (過去式), cycled (過去分詞)

其實一本好的字典你查原型動詞後應該會把過去式(past tense),過去分詞(past participle),甚至現在進行式(+ing的continuous)都會標示的。

swam 不是 swim 的過去分詞, swum 才是過去分詞

Swim
swam (past tense 過去式)
swum (past participle 過去分詞)
swimming (present participle 現在分詞)
