白話解釋

句型是：主詞 + have / has + 過去分詞。

答
答案與解析
- She has already seen the movie.
解析：現在完成式要用 has + 過去分詞 seen。
- I have gone to school.
解析：have 後面要接過去分詞 gone。
- He has finished his homework.
解析：第三人稱單數要用 has，加上過去分詞 finished。
- We have visited the park.
解析：have 後面接過去分詞 visited。
- They have lived here since 2020.
解析：have + 過去分詞 lived，表示從 2020 年起持續到現在。
