何時用ed,何時用ing當形容詞?

請問英文裡的動詞字尾+ed或ing時,可以變成形容詞,那怎樣的動詞是加ed,哪些是用ing?再麻煩舉例一下

在新聞內看到這句,我不確定這句是否只是個分詞構句,extracting和ed / ing的形容詞無關,若無關這句的句子如何拆解?

Surgery found that ※extracting※ plasma by centrifuging it leads to the release of significant levels of growth factors which may promote wound healing and collagen growth

謝謝 Louis 老師, 拍謝點數有限..,容我再問一個句子:

But the New York Times quoted an unnamed investigator as saying that one of the pilots had left the cockpit and had been unable to get back in.

句中的as代表什麼意思,as saying 開始 怎麼沒有主詞....?

    Surgery found that ※extracting※ plasma by centrifuging it leads to the release of significant levels of growth factors which may promote wound healing and collagen growth.

    這裡的extracting是「動名詞」(gerund),當作名詞子句的主詞,其動詞是leads。

    主要子句是Surgery found that xxx.

    形容詞子句which may promote wound healing and collagen growth,修飾先行詞factors

    「分詞構句」是用來當修飾語的,可以是~ing或~ed等分詞形成。

    及物動詞的「過去分詞」用來當修飾語或補語時,有被動及完成的意思:

    Henry is drinking boiled water.(被煮過的水;修飾語)

    不及物動詞的「過去分詞」只有完成的意思:

    The milk was all gone.(已經沒了;補語)

    及物或不及物動詞的「現在分詞」當修飾語或補語時,有主動或同時發生的意思:

    The little girl came running.(同時發生;主動;修飾語)

    Boring teachers make students bored.(前者是主動的修飾語:令人厭煩的;後者是被動的受詞補語:感到厭煩)

    Camping out last summer, we saw a bear.(分詞構句是修飾述部的副詞性質的修飾語,簡單式分詞表示與述部同時發生)

    I like to stay home reading novel and listening to music.(這也是分詞構句)

    Having failed twice, he didn't want to try again.(分詞也可以有完成式,表示時間較主句的動詞早)

    If you quote someone as saying something, you repeat what they have written or said.

    to quote xxx as xxx

    as是配合動詞quote使用的介系詞

    He quoted Mr. Polay as saying that peace negotiations were already underway.

    She was quoted in the Express by an unnamed source as saying: "I won't bail out those two silly girls."
