「考例」 ______ by a greater demand of vegetables， farmers have built more green houses.（2007，浙江） A. Driven B. Being driven C. To drive D. Having driven「解析」 答案A.句意为：受更大蔬菜需求的驱动，农民已经建了更多的温室。本题考查非谓语动词。因为farmers和drive之间是被动关系，所以用过去分词短语作状语，表示原因。 4. Only after you have had that recognition can you say that you are truly an inventor. 只有获得了认证，你才可以说是一个真正的发明者。（P.21） 「点拨」 以 only开头的句子，如果only修饰的是句子的状语或状语从句，句子或主句要部分倒装，但only修饰主语时，句子不倒装。如：Only the students in class 3 can do the exercises. 只有三班的同学才能做这些练习。 「考例」 Only after my friend came ______. （2005，福建） A. did the computer repair B. he repaired the computer C. was the computer repaired D. the computer was repaired 「解析」 答案C.以Only+状语从句开头时主句用倒装语序，应把句中的系动词、情态动词或助动词提前，本题是被动语态，因此答案为C. Phrases set out「原句再现」 Bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. （P.25） [点拨] set out在上句中的意思是“开始，着手做某事”。set out还可以表示“动身，出发”，后常跟介词for. [辨析] set about也有“开始，着手做某事”的意思，但是这两个短语在用法上有所不同：set about后接doing sth.，而set out后接to do sth.。 [拓展] 与set有关的短语：set off 出发，动身（后常接介词for），引爆；set up 建立，创立；set sb. free 释放；set aside 留出，抽出，忽视；set down 记下，写下， 放下；set foot in/on 踏上；set sail 扬帆起航；be set in 以……为背景；set fire to sth. = set sth. on fire 放火烧某物；set sb. an example = set an example to sb. 给某人树立榜样。 [小试] 用上述短语填空。 1. He was quite eager to __________ his hometown since he had left there 30 years ago. 2. You‘d better __________ some time every day to practise your spoken English. 3. The secret of famous writers’ success is to_________ everything that comes to them. 4. The school should __________ finding solutions to pollution of plastic bags around it. 5.
