鏈接•提示
此句型為連詞＋過(guò)去分詞作狀語(yǔ)的用法。過(guò)去分詞作狀語(yǔ)時(shí)，其邏輯主語(yǔ)應(yīng)該和主句的主語(yǔ)一致，且表示被動(dòng)的動(dòng)作。有時(shí)為了更準(zhǔn)確地表示主句和從句之間的邏輯關(guān)系，在過(guò)去分詞的前面使用連詞，相當(dāng)于該連詞引導(dǎo)的狀語(yǔ)從句（從句謂語(yǔ)動(dòng)詞為被動(dòng)）。
練：a beam of light will not bend round comers unless______to do so with the help of a reflecting device.
a.having been made b.being made c.made d.you make
提示:分析句子結(jié)構(gòu)和句子的意思，unless應(yīng)該引導(dǎo)狀語(yǔ)，但句子不完整。可補(bǔ)全句子內(nèi)容為unless it is made to do so，所以正確答案為c項(xiàng)。
答案:c
辨析

即時(shí)練習(xí):
the picture of the park ________memories of our class trip last year.
a.called up b.reminded c.turned up d.came up
提示:call up打電話；使回憶起；召集；remind sb.of...使某人回憶起（賓語(yǔ)為人）；turn up出現(xiàn)；到達(dá)；把……開(kāi)大/擰大；come up上升；提出。根據(jù)句意此處應(yīng)表示“……使我想起了去年我們班的旅行”。

三者都有“盡管”之意，但詞性不同。前兩者為介詞，后跟名詞，通常情況下可換用。而though 是連詞，后跟句子。
