關係代名詞:The strength....

課本例句:

The strength, toughness, and elasticity of silk continue to fascinate scientists, who wonder what gives this natural material its unusual qualities.

請問上述例句為什麼 scientists和who之間要加逗號?不加可以嗎?變成:

The strength, toughness, and elasticity of silk continue to fascinate scientists who wonder what gives this natural material its unusual qualities.

請解釋一下,謝謝。

    ...scientists, who wonder what gives this natural material its unusual qualities

    加逗號代表後面的形容(who wonder what gives this natural material its unusual qualities)是"非必要的," 因為指出是哪幾位科學家並不是本句的重點.

    所以即使沒有後面的形容, 本句依舊可以表達的很完整:

    The strength, toughness, and elasticity of silk continue to fascinate scientists.

    例如:

    @The Professor who teaches Chemistry 101 is an excellent lecturer. 本句中沒有加逗號是因為如果沒有後面的形容"who teaches Chemistry 101,"

    -->The Professor is an excellent lecturer. 那根本就不知道是指哪位Professor.

    @The Professor Wilson, who teaches Chemistry 101, is an excellent lecturer. 此句有加逗號是因為如果沒有後面的形容"who teaches Chemistry 101,"

    -->The Professor Wilson is an excellent lecturer. 本句依然可以指出是哪位Professor.
