第六章代詞
    代詞顧名思義,用來替代前面出現(xiàn)過的成分,以使語言簡(jiǎn)練、避免重復(fù)。
    代詞種類繁多,包括人稱代詞(如:I, him)、物主代詞(如:her, ours, their)、反身代詞(如:yourself, themselves)、指示代詞(如:that, these)、不定代詞(如:every, any)、疑問代詞、關(guān)系代詞等。這里集中講解人稱代詞和物主代詞,其他類型的代詞在其他章節(jié)中分別闡述
    第一節(jié) 人稱代詞
    人稱代詞分為兩類:主格和賓格,人稱代詞的格變化是TOEFL中的一個(gè)常考考點(diǎn)
    考點(diǎn)一 主格
    主格代詞分別是:
    第一人稱:I , we(復(fù)數(shù))
    第二人稱:you(單復(fù)同)
    第三人稱:he, she, it, they(復(fù)數(shù))
    主格代詞在句中作主語,填空題缺少主語時(shí),有時(shí)填主格代詞
    例題:
    (1)
    Long before children are able to speak or understand a language, ----communicate through facial expressions and by making noises.
    (A) however
    (B) they
    (C) furthermore
    (D) who
    答案:B
    解釋:空白前分別是本句的從句和主句,主句中缺少主語, 只有B代詞可獨(dú)立作主語
    (2)
    Every individual cell, whether its exists as an independent microorganism or is part of a complex creature, has its own life cycle.
    應(yīng)改為:it
    解釋:物主代詞its不能與動(dòng)詞exist連用,應(yīng)改為人稱代詞作從句的主語
