      1. 介賓短語的托福語法講解

        時間:2020-09-13 13:01:59 托福(TOEFL) 我要投稿

        關于介賓短語的托福語法講解

          導語:介賓短語是小編上學的時候覺得容易上手的一塊,但是小編最近發現很多在托?荚嚨耐瑢W們在介賓短語這一塊很不熟練,下面小編就為大家分享一篇過于托?荚嚨腵介賓短語干貨!

        關于介賓短語的托福語法講解

          介詞不能單獨使用,而必須和其他詞連用,這些詞稱作介詞的賓語,它們共同構成的介賓短語常在句中作狀語,作名詞的后置定語,有時作某些動詞的賓語補足語

          考點一 名詞作介詞賓語

          大部分介詞的賓語都是由名詞(包括代詞)充當的,如:under the tree, during the day, 這一考點在題中多次出現

          例題:

          (1)

          The development of mechanical timepieces spurred the search for ----with which to regulate them.

          (A) more accurate than sundials

          (B) more accurate sundials

          (C) sundials more accurately

          (D) more accurately than sundials

          答案:B

          解釋:search for缺少賓語, 只有B是表達無誤的名詞詞組, 可以作賓語;其他選項的比較形式都有錯。

          (2)

          Different species of octopuses may measure anywhere from two inches to over thirty feet in long.

          應改為:in length.

          解釋:long 是形容詞, 不能單獨接在介詞之后, 其名詞形式length與in構成介賓短語, 表示長度

          考點二 動名詞作介詞賓語

          名詞作賓語時,之后不能再接賓語,這一缺陷可由動名詞彌補。

          如:before doing the job , after getting back

          改錯題中常把應該用動名詞作賓語的地方誤用為名詞或不定式,需留心陷阱

          例題:

          (1)

          The Conestoga wagon, used for to carry heavy loads over long distances, originatedaround 1725 in a region of Pennsylvania occupied by the Conestoga Indians.

          應改為:carrying.

          解釋:不定式不能作for的賓語, 改為動名詞即可

          (2)

          Copper sulfate, spread in judicious amounts, kills algae ----harming fish or aquatic invert-ebrates.

          (A) does not

          (B) but does no

          (C) except

          (D) without

          答案:D

          解釋:harming 是動名詞形式, 因此要求前面的詞是介詞或可接動名詞的動詞. A B 可首先排除; C 雖是介詞, 但與句意不符.

          (3) Mary Ann Hardy was known for her skill to paint miniature watercolor portraits on ivory.

          應改為:in painting

          解釋:后置定語修飾名詞,什么方面的技能,不能用不定式。
