    同族词都是一家人

      在《前缀一加,词义转变》中提到同族词(见1月17日《中英合谈》)。所谓同族词(family words)便是由同个词根衍生出来的一群实词。例如:“art”(艺术)名词是“art”和“artist”,形容词是“artistic”,副词是“artistically”。虽然这四个字的语音、词形、词类和词义都不同,但都来自共同的词根。

      同族词既然是由同一词根派生而成,它们之间便有“血脉”关系,而且在词义上,也常有相似之处。

      学习英语词汇时,可以利用同族词这特色把每组词集中起来,用对比方式,辨别每个词的词义和不同用法,然后加以记忆和运用,假以时日,不难水到渠成,词汇丰富。

      下面便是两组同族词的意思及其用法:

      Ⅰauthorise(动词)授权、批准

       authorisation(名词)授权、委任

       authoritative(形容词)权威的、命令式的

       authority(名词)权力、职权、权威

       authorities(名词)当局

    ① Dr Li has authorised David to act for him in his absence.

    ② The Ministry for Finance authorised the payment of annual increments.

    ③ One needs special authorisation to enter such a building.

    ④ This news came from an authoritative source, so it must be reliable.

    ⑤ The Commander-in-chief spoke in an authoritative tone.

    ⑥ As a senior officer, Jason is entitled to have authority over the clerical staff.

    ⑦ Who gave you authority to implement the new salary scheme?

    ⑧ Dr Wong is an authority on language teaching.

    ⑨ The authorities concerned must see to it that the same thing will not recur.

       Ⅱclear(形容词)清楚的、明白的、无嫌疑的、债务已清的;

          (副词)远离的

          (动词)清除、解除。

        clearance(名词)清除、许可(证)

            (修饰语)清货

        clearing (名词)林中空旷的

        clearly(副词)清楚地

    ① The speaker's voice is clear enough to be heard.

    ② Can you make your last point clearer?

    ③ The suspect was clear of suspicion.

    ④ The gambler hopes to be clear of debts soon.

    ⑤ Unauthorised persons are advised to keep clear of the premises.

    ⑥ The police have cleared the road of obstruction.

    ⑦ If there exists misunderstanding among friends, please clear it up.

    ⑧ Have you seen any slum clearance?

    ⑨ The plane must get clearance for take-off.

    ⑩ Before Christmas, shopping centres have the habit of holding annual clearance sales.
