成人三級英語高分語法指導(dǎo)二

字號:

有些形容詞本身就具備“最、極”的含義,所以就沒有級和比較級。如:absolute(絕對的),unique(獨一無二的),infinite(無限的),round(圓的),right(對的),correct(正確的),wrong(錯誤的),perfect(完美的),這類形容詞往往被稱為絕對形容詞對于most來講,除了構(gòu)成某些詞級外,most的用法有幾點需要注意,經(jīng)常成為改錯題的考點:
    1、當(dāng)most表示大多數(shù)時,之前不加the,并且有兩種形式來表示大多數(shù),分別為:most + 名詞
    如:most people,most Indian tribes;most + of + 限定詞+ 名詞或代詞,如:most of his paintings,most of us,most of the modern artists
    2、most有時意思等同于very,此時most之前用不定冠詞
    如:
    a most lovely girl,a most impressive proposal
    例題:
    (1)The most substances expand in volume when they are heated.
     A        B   C     D
    答案:A
    應(yīng)改為:Most
    解釋:most只有在表示形容詞級作定語時需加定冠詞,此句表示“大多數(shù)”,沒必要加the
     Aluminum is the most abundant metal in the crust of the Earth,but the nonmetals oxygen
     A          B      C
    and silicon are more still abundant.
     D
    考點:程度副詞
    答案:D
    應(yīng)改為:still more
    解釋:程度副詞still修飾比較級more時,應(yīng)置于其前。
    幾點參考規(guī)則:
    1、多數(shù)副詞放在修飾的動詞之后,若動詞有賓語則放在賓語之后,如:She sings very well.
    I met your uncle(動詞的賓語)just now.
    I met just now your uncle (錯)
    2、副詞修飾形容詞、介詞短語、副詞時常放在被修飾成分之前,如:These two are only slightly different.
    right after this,very smoothly
    當(dāng)然,副詞enough是一個例外,要放在修飾成分的后面,如:I am not good enough to do this job. (對)
    I am not enough good to do this job. (錯)
    3、表示頻率的副詞常放在實意動詞之前,be動詞之后,如:He often/ always/ rarely/seldom/never play(實意動詞) tennis、He is always here at 8'clock.(be動詞之后)
    4、部分副詞的位置沒有一定的規(guī)定,原則上接近被修飾詞即可,如:only,even,still,perhaps。
