最近閱讀文章有看到下列標題
Ottawa Public Health or a health care provider has instructed me to
self-isolate because I have been in close contact with a person" who is being
tested for COVID-19" or has COVID-19.
想請教非常基礎的文法問題....想請問為什麼這邊不是who is tested for
而是 who is being tested 呢?
這個是文法內的哪一部分呢?我應該往"現在分詞"用法的方向搜尋?
感謝大家....
