-Oh，it's hard to do that．

Answer 1

分析 ---考試前，老師們總是告誡學(xué)生盡量避免犯以前犯過的錯(cuò)誤．
---很難做到．

解答 答案：are always told to try to avoid making mistakes that they made before．這里是表示經(jīng)常always的動(dòng)作，用一般現(xiàn)在時(shí)，告誡某人做某事tell sb do sth，主語students是動(dòng)詞tell的承受者，故用一般現(xiàn)在時(shí)的被動(dòng)語態(tài)am/is/are+過去分詞，tell的過去分詞是told，改為被動(dòng)語態(tài)的時(shí)候需加上動(dòng)詞不定式符號(hào)，故be told to do sth，主語students復(fù)數(shù)，故are，盡力做某事try to do sth，避免做某事avoid doing sth，犯錯(cuò)make mistakes，故are always told to try to avoid making mistakes，mistakes作為先行詞，植物，用關(guān)系詞that引導(dǎo)的定語從句，之前犯的錯(cuò)誤表示的是過去的事情用一般過去時(shí)，make的過去式made，故 that they made before，故答案是are always told to try to avoid making mistakes that they made before．

點(diǎn)評(píng) 在make，let，have等使役動(dòng)詞和see，watch，notice，hear，feel等感官動(dòng)詞后的復(fù)合賓語中，動(dòng)詞不定式不帶to．
