英语学习,背诵单词是一个持久的过程,同学们可以利用自己的业余时间背诵和记忆单词,比如说是等车的时间,或是早晨刷牙的时间。下面是小编为大家整理的有关高二英语必修五知识点总结,希望对你们有帮助!
【一般过去时】
一般过去时表示过去某一时候或某一段时间所发生了的事情或存在的状态。常与过去时间yesterday, this morning, just now, a moment ago, in May, last night / year / week, once upon a time, the other day, before …, when – clause, in the past连用。如:
What did you do yesterday? 昨天你干了什么?
I met Lin Tao this morning. 今天上午我会到了林涛。
I was there a moment ago. 刚才我在那儿。
2. 一般过去时的应用
Liu Ying was in America last year. 刘英去年在美国。
Jim rang you just now. 吉姆刚才给你打了电话。
(2) 表示过去经常或反复发生的动作。常接时间副词often, usually, always, sometimes, every day / week, etc. 如:
We often went out for a walk after supper. 我们过去常在晚饭后散步。
We usually played together. 我们通常一起玩。
[page]
一般过去时的谓语动词要用动词的过去式。动词过去式的构成分规则变化和不规则变化两种形式,不规则变化通常需要逐个记忆,规则变化则遵循以下原则:
(1) 一般在动词后加-ed。如:play—played, offer—offered, weigh—weighed, destroy— destroyed, sign—signed.
(2) 在以字母e结尾的动词后,只加-d。如:like—liked, provide—provided, hate — hated, date—dated。
(3) 在以“辅音字母+y”结尾的动词后,则改y为i,再加—ed。如:supply—supplied, fly—flied, study— studied.
(4) 在以单短元音的重读闭音节结尾且,末尾只有一个辅音字母的动词后,双写最后一个辅音字母,再加-ed。如:plan—planned, refer—referred, regret—regretted, ban—banned.
4. 特别说明
有些动词的过去时,如:expect, hope, intend, plan, wanted 等一般过去时,后接不定式的完成时;或它们的过去完成时接不定式的一般式,都可表示过去未曾实现的意图、打算或希望。如:
I hoped to have been invited to his wedding party. —I had hoped to be invited to his wedding ceremony. 我本希望他来邀请我参加他的婚礼。
I intended to have joined their games. —I had intended to join their games. 我本打算参加他们的比赛。
【现在完成进行时】
现在完成进行时表示某动作从过去某个时间开始,一直延续到现在,并且还有可能持续下去。如:
We have been waiting for him for two hours. 我们等他等了两个小时。
现在完成进行时由“have /has been + 现在分词”构成。
3. 现在完成进行时的应用
现在完成进行时所用的时间状语:this month / week / year, these days, recently / lately, in the past few + 时间段, since +时间点, for + 时间段。如:
They have been building the bridge for two month. 两个月来他们一直在修桥。
They have been planting trees this month. 这个月来他们一直在植树。
(1) 现在完成时强调动作的完成,而现在完成进行时强调动作的延续,因此,表示动作的完成,只能用现在完成时,而不能用现在完成进行时。如:
He has changed his idea. 他改变了想法。
(2) 在表示动作的延续时,虽然既可用现在完成时,也可用现在完成进行时,但现在完成进行时强调动作的进行。因此在需要明确表示动作还要持续下去时,应用现在完成进行时。如:
We have been studying here for two years. 我们在这儿已经学习了两年了。
(3) 有些延续性动词(如 keep, learn, live, stay, study, work等),用于现在完成时或现在完成进行时的区别不大。如:
I have lived here for many years.=I have been living here for many years. 我在这儿住了多年了。
1 系动词
系动词亦称联系动词(Link Verb),作为系动词,它本身有词义,但不能单独用作谓语,后边必须跟表语(亦称补语),构成系表结构说明主语的状况、性质、特征等情况。说明:有些系动词又是实义动词,该动词表达实义时,有词义,可单独作谓语。例如:
He fell ill yesterday. 他昨天病了。(fell是系动词,后跟补足语,说明主语情况。)
He fell off the ladder. 他从梯子上摔下来。fell是实义动词,单独作谓语。
用来表示主语状态,只有be一词。例如:
He is a teacher. 他是一名教师。(is与补足语一起说明主语的身份。)
2)持续系动词
用来表示主语继续或保持一种状况或态度,主要有keep, rest, remain, stay, lie, stand。例如:

The search proved difficult. 搜查证实很难。
His plan turned out a success. 他的计划终于成功了。(turn out表终止性结果)

1)协助主要动词构成谓语动词的词叫助动词。被协助的动词称作主要动词。助动词自身没有词义,不可单独使用。例如:
