2017届高三广东北师大版英语一轮复习学案： M2 unit 4 Cyberspace（1） 1. come true 指愿望实现,预言成真,不可用于被动语态 His wish to be an actor has come true. 他想当演员的愿望实现了。 与come true 同义的有realize, 但它是及物动词, 可用于被动语态。 She worked hard to realize her dream. 她为了实现她的梦想而努力工作。 2. cause, reason与excuse ①三个词都可以作名词，cause是自然造成某种结果的原因；reason指在事实的基础上通过逻辑判断出来的理由，常与for短语连用；excuse表示“辩解，借口”，指为某一行为所做的解释，可以是真的，也可以是托词。 make up an excuse 编造一个借口 Too much work is no excuse for not studying. 工作太多并不是不学习的借口。 Heart trouble is one of the most serious causes of death among old people. 心脏病是导致老年人死亡的最重要的原因之一。(不用reason) The reason (why) I was absent yesterday is that I was sick. 我昨天缺席的原因是我生病了。(不用cause) We have no reason to disbelieve him. |
