【考點(diǎn)】 break down可作及物動(dòng)詞,作“破壞;使失效”解。也可作不及物動(dòng)詞,常表示“(計(jì)劃,談判等) 受挫折、失敗”或“感情失去控制”或“(機(jī)器)停止運(yùn)轉(zhuǎn)”。
【考例】 News reports say peace talks between the two countries______ with no agreement reached.(NMET 2003)
A. have broken down
B. have broken out
C. have broken in
D. have broken up
【解析】由with no agreement reached (沒(méi)達(dá)成任何協(xié)議)這一提示可知,全句要表達(dá)“和談失敗”之意。而break up“驅(qū)散,分開(kāi)”;break in “插嘴”;break out“爆發(fā)”,都不符合句意,可排除。break down意為“(談判等)失敗”,符合句意,故選A。
2. She spends much of her time telling others about her disease and encouraging people to learn how to protect themselves. (Reading)
【考點(diǎn)】 及物動(dòng)詞encourage的意思是“鼓勵(lì)”,表示“鼓勵(lì)某人做某事”用encourage sb. to do sth.。
【考例】 My advisor encouraged ______ a summer course to improve my writing skills. (北京2004)
A. for me taking B. me taking

【考點(diǎn)】 過(guò)去完成進(jìn)行時(shí)的構(gòu)成是“had+ been+ doing”,表示從過(guò)去某時(shí)間開(kāi)始到過(guò)去另一時(shí)間為止,該動(dòng)作一直在持續(xù)進(jìn)行著,它具有過(guò)去完成時(shí)和過(guò)去進(jìn)行時(shí)二者的特征。
【考例】 The crazy fans ______ patiently for two hours’ and they would wait till the movie star arrived.(重慶2004)
A. were waiting
B. had been waiting
C. had waited
D. would wait
【解析】從and后的分句可知電影明星還沒(méi)有到,所以當(dāng)時(shí)還在“等”,體現(xiàn)了進(jìn)行時(shí)態(tài);從第一分句的時(shí)間狀語(yǔ)for two hours可知是過(guò)去完成時(shí),由此可知用過(guò)去完成進(jìn)行時(shí),故選B。
