托福考試輔導(dǎo):語法講解(46)

字號:

第二節(jié) 狀語
    句子中除了主謂結(jié)構(gòu)外,還可能包含表示時(shí)間、地點(diǎn)、方式等內(nèi)容的狀語,通常由副詞、介賓短語來承當(dāng)。
    如:At night, I don’t go out very often., 此句中at night, very often都是狀語
    介賓短語作狀語是填空題的重要考點(diǎn),若空格處或空格所在部分之后是完整的主謂句,且兩部分之間多以逗號隔開,若選項(xiàng)中無從句結(jié)構(gòu)或分詞,此時(shí)空格處需填入介賓短語作狀語。
    例題:
    (1)
    ----irritating effect on humans, the use of phenol as a general antiseptic has been largely discontinued.
    (A) Its
    (B) Where its
    (C) Since its
    (D) Because of its
    答案:D
    解釋:此句主干完整, 主語是the use of phenol as a general antiseptic, 謂語是has been largely discontinued, 逗號之前應(yīng)是狀語. A構(gòu)成名詞短語, 與該句主語發(fā)生沖突; B、C欲構(gòu)成從句, 但缺少從句的謂語動(dòng)詞; D恰好構(gòu)成表示原因的狀語, 短語because of 之后常接名詞或動(dòng)名詞表原因, 如: He failed the exam because of his carelessness.
    (2)
    ----a child, sculptor Anne Whitney showed an eager intellect and artistic talent that her parents recognized and encouraged.
    (A) Has been
    (B) It was while
    (C) She was
    (D) As
    答案:D
    解釋:此句主干完整, 主語是sculptor, 謂語動(dòng)詞是showed, 之后是帶有定語從句的賓語, 需填入狀語. A、B、C 中的has been、was與showed相沖突, 違背謂語原則. 介詞詞組As a child 相當(dāng)于When she was a child.
    (3)
    .----, snakes frequently subdue their prey without injecting poison.
    (A) Contrary to general belief
    (B) General belief contrary to
    (C) Belief contrary to general
    (D) Contrary belief general to
    答案:A
    解釋:給出部分是完整的句子, 從選項(xiàng)中可見此處缺少狀語, be contrary to是固定詞組, 表示“與……相反”, 介詞to后需接賓語, 只有A符合上述條件
