三、考查過去分詞用作狀語

過去分詞用作狀語的典型特征是：表被動，可視為其前省略了“主語（即主句主語）+助動詞be”。這類過去分詞（短語）通常可根據(jù)具體的語境轉(zhuǎn)換成相應(yīng)的狀語從句——即表原因的過去分詞短語可轉(zhuǎn)換成原因狀語從句，表條件的過去分詞短語可轉(zhuǎn)換成條件狀語從句，等等。如：

1. _________ for the breakdown of the school computer network, Alice was in low spirits. (福建卷)

A. Blaming                           B. Blamed

C. To blame                         D. To be blamed

【說明】此題答案選B。根據(jù)句意可知，Alice與blame為被動關(guān)系，故選過去分詞。Blamed for…在此表原因，故可轉(zhuǎn)換成原因狀語從句：Because she was blamed for the breakdown of the school computer network…

2. _________ in the mountains for a week, the two students were finally saved by the local police. (江蘇卷)

A. Having lost                      B. Lost

C. Being lost                        D. Losing

【說明】此題答案選B。lose oneself in 為固定短語，其意為“在……迷路”，由于題中沒有oneself，所以可以斷定the two students與lose是被動關(guān)系，故用過去分詞。Lost in the mountains for a week在此表時間，可轉(zhuǎn)換成時間狀語從句：After they had been lost in the mountains for a week…

注：有時用作狀語的過去分詞前帶有自己的“引導(dǎo)詞”。如：

3. No matter how frequently _________, the works of Beethoven still attract people all over the world. (廣東卷)

A. performed                      B. performing    

C. to be performed              D. being performed

【說明】此題答案選A。performed為they are performed之省略。

4. When _________help, one often says, “Thank you.” Or “It’s kind of you.” (福建卷)

A. offering                          B. to offer

C. to be offered                   D. offered

【說明】此題答案選D。“給某人提供幫助”說成英語是offer sb help，根據(jù)句意可知，one與offer為被動關(guān)系，即當(dāng)一個人說“謝謝”時，他應(yīng)當(dāng)是“被”提供了幫助，所以空格外填過去分詞。When offered help…可視為When he is offered help…之省略。
