2. 分詞短語作定語，放置于中心名詞后面
解題要點(diǎn) 分詞短語作后置定語在TOEEL考題中出現(xiàn)頻率非常高。因而，考生務(wù)必熟記這一結(jié)構(gòu)和用法。實(shí)際上，分詞短語作后置定語。皆是定語從句的省略形式。

(2) The slide rule used sliding scales with marks ------- numbers and their logarithms.
(A) representing
(B) represented
(C) are represented
(D) they are representing

(4) The bison know for the hump over its shoulders is usually called a buffalo in North America. (91.1)
[答案] A 此句主語是The bison ,謂語是系詞is ,劃線A部分應(yīng)當(dāng)為分詞短語，修飾名詞The bison .A應(yīng)改為known for。

[答案] D 修飾名詞books應(yīng)用分詞生語ever written。
3. 分詞短語作狀語
解題要點(diǎn) 在句了意義非常清楚明確時(shí)，狀語從句通常可以簡略為分詞短語，但有一個(gè)先決條件。此分詞短語的邏輯主語應(yīng)與句子的主語為同一人或物，此類分詞短語通常置于句首。
全真例題分析

(A) Founded
(B) Founding
(C) To found
(D) Having founded
[答案] A 分詞短語表示時(shí)間，其邏輯主語即是句子主語The Boston Latin School.

4. 現(xiàn)在分詞表達(dá)主動(dòng)的.概念;過去分詞表達(dá)被動(dòng)的概念
全真例題分析
(1) Tudging to be the best boxer of his time, sugar Ray Robinson lost only 3 out of 137 fights (94.1)
[答案] A 此分詞短語與其邏輯上的主語sugar Ray Robinson 是被動(dòng)的關(guān)系(Sugar was judged to be…) 故應(yīng)用過去詞Tudped to be.
(2) During the Colonial days, the Iroquois had an agricultural economy basing mainly on corn with supplementary crops of pumpkins ,beans, and tobacco.
[答案] B通常我們說to be based on ，這個(gè)短語表示被動(dòng)概念(基于，以…為基礎(chǔ))，所以應(yīng)改用過去分詞based。
(3) Per capita income is a nation*s entire income dividing by the number of people in the nation.
[答案] B根據(jù)句意及分詞dividing后面的介詞by，可以推斷這個(gè)分詞短語表達(dá)的是被動(dòng)的概念，因此，應(yīng)用過去分詞divided by。
(4) Clementine Hunter*s primitive paintings have been exhibited at various galleries. Included one at the Smithsonian Institution in Washington. D.C.
[答案] D 分詞in cluded與其邏輯的主語paintings并無被動(dòng)的關(guān)系，不應(yīng)用過去分詞，應(yīng)改為慣用現(xiàn)在分詞短語in cluding + 名詞賓語的結(jié)構(gòu)
