托福考試輔導(dǎo):語(yǔ)法講解(51)

字號(hào):

第三節(jié) 并列句中的省略
    并列句中當(dāng)后面的分句與前面有相同部分時(shí)可進(jìn)行省略,以避免重復(fù),省略時(shí)前后要盡量保證結(jié)構(gòu)的平衡
    如:I major in history and my brother in chemistry.
    He was eager to win her heart, but didn’t know how.
    TOEFL中有少量題目涉及這一語(yǔ)言現(xiàn)象
    例題:
    (1)
    The photoperiodic response of algae actually depends on the duration of darkness, ----.
    (A) the light is not on
    (B) and not on light
    (C) but is not on the light
    (D) is not on light
    答案:B
    解釋?zhuān)嚎崭袂笆蔷渥拥闹髦^語(yǔ), A, D可先排除;正確的搭配是depend on, 而不是is on, C也有誤;B是省略了的并列句,相當(dāng)于and does not depend on light, 符合語(yǔ)法
    (2)
    Nebraska has floods in some years, ----
    (A) in others drought
    (B) droughts are others
    (C) while other droughts
    (D) others in drought
    答案:A
    解釋?zhuān)嚎崭袂笆峭暾闹髦^句,逗號(hào)不能連接句子,故主謂結(jié)構(gòu)B可先排除;C從句少謂語(yǔ);D語(yǔ)義不明;A是簡(jiǎn)略的平行結(jié)構(gòu),相當(dāng)于and drought in others (other years)
