選修8 Unit 3 課堂輔導(dǎo)
a. driven b. being driven c. to drive d. having driven「解析」 答案a.句意為：受更大蔬菜需求的驅(qū)動，農(nóng)民已經(jīng)建了更多的溫室。本題考查非謂語動詞。因為farmers和drive之間是被動關(guān)系，所以用過去分詞短語作狀語，表示原因。
4. only after you have had that recognition can you say that you are truly an inventor. 只有獲得了認證，你才可以說是一個真正的發(fā)明者。（p.21）
「點撥」 以 only開頭的句子，如果only修飾的是句子的狀語或狀語從句，句子或主句要部分倒裝，但only修飾主語時，句子不倒裝。如：only the students in class 3 can do the exercises. 只有三班的同學(xué)才能做這些練習(xí)。
「考例」
only after my friend came ______. （，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+狀語從句開頭時主句用倒裝語序，應(yīng)把句中的系動詞、情態(tài)動詞或助動詞提前，本題是被動語態(tài)，因此答案為c.
phrases set out「原句再現(xiàn)」 bell never set out to invent the telephone and what he was trying to design was a multiple telegraph. （p.25）
[點撥] set out在上句中的意思是“開始，著手做某事”。set out還可以表示“動身，出發(fā)”，后常跟介詞for. [辨析] set about也有“開始，著手做某事”的意思，但是這兩個短語在用法上有所不同：set about后接doing sth.，而set out后接to do sth.。
[拓展] 與set有關(guān)的短語：set off 出發(fā)，動身（后常接介詞for），引爆；set up 建立，創(chuàng)立；set sb. free 釋放；set aside 留出，抽出，忽視；set down 記下，寫下， 放下；set foot in/on 踏上；set sail 揚帆起航；be set in 以……為背景；set fire to sth. = set sth. on fire 放火燒某物；set sb. an example = set an example to sb. 給某人樹立榜樣。
[小試] 用上述短語填空。
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. many shelters would be ______for victims whose houses were damaged in the big earthquake. 6. the man who __________ the supermarket has been caught.
