8、动词的过去时,则从句表示的时间是“从动作开始的那一时刻起”。例如:He has studied very hard since he came to our school.自从他来到我们学校,他学习就非常努力。若since引导的状语从句的谓语动词是持续性动词或表示状态动词的过去式时,则从句表示的时间是“从动作或状态结束时算起”。例如:I havent heard any noise since I slept. sleep为持续性动词,sleep的动作结束时,即“醒来”时,所以这句应译为“我醒后还未听到任何声音”。5.

21、 teacher,not daring to look up.这个小男孩站在老师面前不敢抬头。Ive never dared (to) ask her.我从来不敢问她。拓展：dare可用作情态动词,用作情态动词时,意思是“敢”,其后接动词原形,通常只用于否定句或疑问句以及if或whether之后,一般不用于肯定句。例如:Dare you tell her the truth?你敢告诉她事实真相吗?I dont know whether he dare try.我不知他是否敢试一试。I darent ask her for a rise.我不敢要求她加薪。(2)for表目的“为了”。如:What
22、 did you do that for?你干吗这样做?Thats what were here for.这正是我们来的目的。易错警醒在通常情况下,英语不用for doing sth.来表示目的。如:他去那儿看他叔叔。误:He went there for seeing his uncle.正:He went there to see his uncle.但是,若一个动名词已名词化,则可与for连用表目的。如:He went there for swimming.他去那儿游泳。(swimming已名词化)10. Now shes not shy anymore and loves singin
23、g in front of crowds.现在她不再害羞,喜欢在众人面前唱歌。not. anymore也等于not.any more或no more,意思是“不再”。例如:The baby no more cried.=The baby didnt cry any more.这个小孩不再哭了。辨析：no more,not.any more,no longer与not. any longerno longer(=not.any longer),主要用来表示时间或距离的“不再”,意在对现在的情况和过去的情况加以比较,所以多用于现在时。它一般修饰延续性动词,表示某个动作或状态不再延续下去。例如:Yo

26、l you be able to cure him,Doctor?医生,你能把他治好吗?辨析：be able to与canbe able to强调通过努力而获得的能力,而can则强调自身已具有的能力。如:She can sing the song in English.她能用英语唱这首歌。He will be able to sing this song in English in a few minutes,too.几小时之后,他也能用英语唱这首歌。be able to强调一种结果,而can只强调一种可能。如:Luckily,he was able to escape from the bi

28、ble to通常不这样用。The man cant be my teacher.那个人不可能是我的老师。易错警醒can有被动语态,主语为人或物皆可,而be able to只接不定式的主动形式,不接表示被动的不定式,也不可用无生命的名词作主语。例如:The work is able to be done by him.(误)He is able to do the work.(正)例1 How does Jack usually go to work?He _drive a car,but now he _there to lose weight.A. used to;is used to wa
