this habit.He once paid a visit to a town，where accommodation was free.One morning something awesome happened to him.He was jogging near the boundary when he was targeted by some soldiers，who hid themselves behind a steep bank of a shallow river，just opposite to him.Sharp whistles of the bullets urged him to flee as fast as possible.Luckily，he narrowly escaped being killed，by pure coincidence.He sucked in deep breaths before calming himself down.This event made him aware of the truth that caution is the parent of safety.‎ 默写识记 ‎◆默写单词 ‎1．witness vt. 　 当场见到；目击 n. 目击者；证人；证据

cars had a headon crash.The traffic was held by the accident.I hurried closer to the scene and the meantime I called for an ambulance.I managed to help the injured drivers and three other people out

done ‎[教材原句]　A large wiselooking turtle was passing so close to ‎ me that I could have touched it.‎ 一只长相聪慧的大海龟紧贴着我的身旁游过，伸手便可触及。‎ could have done sth.意为“本来能做某事(却没做)”，表示一种责备、埋怨或训斥等语气，与should have done sth.的意思差不多。另外，might have done sth.“本来会做某事(却没做)”也表示同样的语气。‎ You could have warned me she was coming.‎ 你本应该告诉我她要来的。‎ I could have lent you the money.Why didn't you ask me?‎ 我本来可以把钱借给你的，你为什么没有向我借呢？‎ could have done与might have done也可表示推测语气，意为“可能做了某事”，could多用于否定句或疑问句中，这时与can have done和may have done用法相同。‎ She couldn't/can't have been to London，for she knows nothing about it.‎ 她不可能去过伦敦，因为她对伦敦一无所知。‎ He might/may have gone to sleep，for the light is turned off.‎ 他可能已经睡觉了，因为灯已经熄灭了。‎ It was a time when...‎ ‎[教材原句]　It was a time when the killer whales，or “killers” as they were then called，helped the whalers catch the baleen whales that were on their annual migration.‎ 那个时期，虎鲸(当时被称为“杀手”)帮助捕鲸人在每年须鲸迁徙时捕捉须鲸。‎ It was a time when...意为“那是一个……的时期”，when引导的是一个定语从句。而There was a time when...则意为“曾经……‎ ‎；那时候一度……”。‎ It was a time when no one felt safe even staying at home.那个时期，人人自危，即使待在家里也感觉不安全。‎ There was a time when this kind of music was very popular.这种音乐曾经很流行。‎ where引导地点状语从句 ‎[教材原句]　The water was quite shallow but where the reef ended，there was a steep drop to the sandy ocean floor.‎ 水很浅，但到了珊瑚礁的尽头，就有一个陡坡，一直下降到满是沙子的海底。‎ where the reef ended是地点状语从句。where引出的地点状语从句一般放在主句之后，但在一些谚语中、表示抽象意义的句子中或强调地点状语时，常把地点状语从句放在主句之前。此时的where大体相当于in/at the place where，所以不可像引导定语从句的where那样换成in/at which。‎ Don't leave the medicine bottle where the children can get it.不要把药瓶放在孩子们够得着的地方。‎ Where there is a will，there is a way.有志者，事竟成。‎ As far as I'm concerned，you are free to go wherever you like.‎ 就我个人而言，你愿意去哪里就去哪里。‎ 即时演练 Ⅰ.[原创]语境填空 ‎1．Where the road
