there be句型
there be句型的概念:
英语中的there be结构主要表示某处存在有某物,所以通常被称为存在句。其中的there为引导词,无词义,be为谓语动词,therebe后面的名词为句子主语。therebe结构的否定式和疑问式:
&1、否定式:there be结构的否定式通常应将否定词置于动词be之后: 如:There is not any bread left. 没有一点面包了。 &&&&&&& There isn't anything I can do for you. 我帮不了你什么忙。若谓语中包括有助动词或情态动词,通常将否定词置于助动词与情态动词之后: 如:There can't be so many mistakes. 不可能有那么多错误。 &&&&&&& There shouldn't be any doubt about it. 对此不应有什么怀疑。 &&&&&&& There haven't been any parties in weeks. 好几个礼拜没开过晚会了。另外注意以下类型的否定式: 如:There doesn't seem to have been any difficulty over the money question. 在钱的问题上似乎没发生什么困难。 2、疑问式:there be结构的疑问式通常应将否定词置于动词be之后: 如:Is there any good film on? 映什么好电影吗? &&&&&&& Is there room for me in the car? 车子里还有我坐的地方吗? &&&&&&& Are there any letters for me? 有我的信吗? 若谓语中包括有助动词或情态动词,通常将助动词或情态动词移至句首构成疑问式: 如:Has there been an accident? 出事了吗? &&&&&&& Have there been any new developments? 有什么新的发展吗? &&&&&&& Can there have been so much rain there?那儿会下过那么多雨吗?另外注意以下类型的疑问式: 如:Uncle Jesse, why do there have to be poor people like those? 杰西叔,为什么一定要有他们那样的穷人? there be结构的谓语形式:1、主谓一致问题:&若只有一个主语,谓语的数则取决于该主语的数;若有几个主语并列,则通常是与靠近的主语保持一致: 如:There is a man at the door. 门口有个人。 &&&&&&& There are some girls in the room. 房间里有几个女孩。 &&&&&&& There is a pen and some books on the desk. 桌上有一支钢笔和一些书。 2、时态问题:there be结构的时态由其中的谓语动词be来体现,它可以有一般现在时、一般将来时、一般过去时、现在完成时以及过去完成时等多种时态形式: 如:There is going to be[will be] an English film tonight. 今晚将有一场英语电影。 &&&&&&& There was a lot to be done. 有很多事要做。 &&&&&&& There were some children swimming in the river. 有些小孩在河里游泳。 &&&&&&& There have been many such accidents. 已发生了好几起那样的事故。 &&&&&&& There had been two seafights between them. 他们之间发生了两场海战。 3、与情态动词连用:there be结构有时可以与情态动词连用: 如:There may be a storm tomorrow. 明天可能有风暴。 &&&&&&& There used to be a hospital here. 原来这里有家医院。 &&&&&&& He felt there must be something wrong. 他感到准有什么问题。 &&&&&&& There might still be hope. 可能还有希望。 &&&&&&& There ought to be a comma here. 这儿应有一个逗号。 4、动词be换成其他动词:有时可将there be中的动词:be换为live, remain, seem, appear, exist, stand, lie, come等: 如:Once upon a time there lived a man known by the name of Joe Beef. 从前有个人名叫乔·比夫。&&&&&&&&&There seems[appears] something the matter with her. 她好像是出了什么事似的。 &&&&&&& There existed different opinions on this problem. 对这个问题曾有不同看法。 &&&&&&& There remained just twenty-eight pounds. 只剩28英镑了。 &&&&&&& At the top of the hill there stands an old temple. 在小山顶上有一座古庙。 5、与其他动词搭配使用:there be结构有时可与其他动词搭配使用,构成一种复合谓语: 如:There seemed to be nobody about, so I went in. 附近似乎没有人,因此我就走了进去。 &&&&&&& There happened to be a man walking by. 恰好有一个人从旁经过。
therebe结构的非谓语形式: 基本结构:there be结构的非谓语形式有两种基本结构,即there being和there to be:1、there being结构该结构的主要用法有: (1)用作状语: 如:There being nothing else to do, we went home. 由于没什么其他的事要干,所以我们就回家了。 &&&&&&& There having been no rain, the ground was dry. 由于没有下雨,所以地面很干。【注】有时可与状语从句转换: 如:There being no further business(=As there was no further business), I declared the meeting closed. 由于没有别的事了,我宣布闭会。 (2)用作介词宾语: 如:There is now some hope of there being a settle ment of the dispute. 现在有点希望可以解决这次争端。 2、There to be结构该结构的主要用法有: (1)用作动词宾语:该结构可用作某些动词(如like, prefer, hate, want, mean, intend, expect, consider等)的宾语: 如:I don't want there to be any misunderstanding. 我可不希望有任何误解。 &&&&&&& Students hate there to be too much homework. 学生讨厌做太多的家庭作业。 &&&&&&& We expect there to be more discussion about this. 我们期望能对此展开更多的讨论。【注】在let there be结构中,动词be不带to: 如:Don't let there be any noise. 不允许有任何吵闹。 &&&&&&& Let there be no mistake about it. 这事不要出错。 (2)用作介词for的宾语: 如:They asked for there to be another meeting. 他们要求再开一次会议。【注】用作介词宾语一般用there being,但用作介词for的宾语时,只能用there to be。比较:They planned on there being another meeting. 他们打算再开一次会议。 &&&&&&&&&&& They planned for there to be another meeting. 他们打算再开一次会议。几个重要句型和结构:

提问者采纳
而不了解其用法。换言之. You don&#39。 He slept until ten o&#39. 自从我生病以来:I have not heard from him since I lived in Shanghai,则表示动作和状态延续到现在(说话时刻), and is still studying it now,第二句不对,我们已换了三个校长了,他屡次给我写信, get married等, once,表示&quot、月.He has never been to see me since I have been ill,since引导的从句持续动词的一般过去时和现在完成时所表示的意思恰好相反;做……直到……&quot。 一. 4) It is +一段时间+ since从句 It is two years since I became a postgraduate student 5. Since I’ve been at this school。 由此可见, not at all,与表示持续意义的as long as(象……一样长;现在完成时为过去发生的.自从我病愈以来, last. 他一直睡到10点;t need to describe her。 I have lived here for more than twenty years,后者是口语说法.;m sorry to keep you waiting,此处不再多述。 二. will be 答案A, half past six)? (强调起床的动作已发生过了。as soon as、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的动词的过去时时. Considerable time has elapsed since we have been here. 她已从巴黎回来了, already,强调动作, in1980。) Who hasn&#39. had met B。 一般过去时的时间状语,就再也没有收到他的信: He has studied very hard since he came to our school,他们已换了三个校长了。 I worked here for more than twenty years,如live. White? It is half a month since he was a League member,将该句译为。Remember是持续性动词,sleep的动作结束时,引导条件状语从句. Sleep 为持续性动词,强调的是影响,他从未来看过我,这一结构中。(表经历) 2) 用于till /s already been sent for。 It’s been quite some time since I was last in London我离开伦敦已很长时间了;也可表示持续到现在的动作或 状态。其构成。如.延续动词与瞬间动词 1) 用于完成时的区别 延续动词表示经验1,前者以肯定的语法形式反映着否定的逻辑内容。 2, die. 4,即“醒来”时, up to now,several times告知为反复发生的动作, till &#47,则从句表示的时间是“从那持续动作或状态结束时算起”, and is still getting married now, leave.比较过去时与现在完成时 1)过去时表示过去某时发生的动作或单纯叙述过去的事情,since引导的从句绝对不能用否定式的谓语动词来表示否定意义,在这种结构中,强调过去的事情对现在的影响, become、日期。 本文开始出现的那个句子就可以译为“自从我离开上海, finish。”而实际上这个句子的译文并非如此. 句子中如有过去时的时间副词(如 yesterday。 You haven’t come to see me for two months。如.---I&#39. have met C. have been B: How long is it since you lived in Shanghai。 2)过去时常与具体的时间状语连用. (我现在已不在这里工作,其表示的时间的起点应从动作发生之时算起:并非有for 作为时间状语的句子都用现在完成时,而现在完成时通常与模糊的时间状语连用.他退团(不当团员)半个月了,应用现在完成时关于since. I ___ here only a few minutes、若since引导的状语从句的谓语动词是终止性的过去时.自从我离开这所学校。) I have seen this film. A, study。 这里has lived表示动作的持续性,我知道她的模样. 他已完成了那项工作; 瞬间动词用于否定句。例如. It’s two months since you didn’t come to see me. Some new oilfields have been opened up since 1976, they have hclock. 注意。 (错)Tom has written a letter to his parents last night. = Tom began to study Russince的用法主要有两点,或无时间状语;t come back until ten o&#39。) Why did you get up so early, 具体的时间状语 共同的时间状语,…ago, go; 瞬间动词表示行为的结 果: It is a long time since he didn’t study English. meet 答案B. (现在我仍在这里工作. My aunt has worked in a clinic since 1949;ve known him since then:“开始居住”时算起. 3: yesterday。 He has never been to see me since I was ill;只要……)连用。 She returned yesterday,他学习就非常努力。) 小窍门. 她是昨天回来了. 比较since和for Since 用来说明动作起始时间,持续到现在, always:1。因此此句可理解为“自从他(开始)住在那儿起, last week。 I have been here since 1989, yet, in October: I saw this film yesterday. ---Oh。) I have finished my homework now,电影的内容已经知道了. 或 Harry has been married for six years。 Since I was at this school. 不少人会望文生义.自从他来到我们学校, just now,那么正确的含义是什么呢. had been C,我们每年都去野营、钟点,for用来说明动作延续时间长度. I ___ until: this morning,不能使用现在完成时。 应注意的是。前者是规范说法,要用过去时,lately 现在完成时的时间状语 for。 He has been in the League for three years,他就屡次给我写信:He has written to me frequently since I was ill. (强调看的动作发生过了, tonight. I have not heard from my uncle for a long time, since, in 1960)时:6B 词义辨析语句连贯尽(as long as)作者所能记忆的, know,我就一直没收到他的来信”,this April,我们不妨再多举几个例子看看, now。 试比较, week. ---Will somebody go and get Dr,时间的起点应从,before.自从我到这所学校,它应改为 Harry got married six years ago。 典型例题 1. since的四种用法 1) since +过去一个时间点 (如具体的年,下面两句都错了。) She has returned from Paris,joined为短暂行为, recently,在使用时就会造成错误, so far: 当现在完成时+一段时间,不能与表示段的时间状语连用。 He has completed the work. 2) (错) Harry has got married for six years,可能为不公平竞争, ever. 自从我病愈以来。(从句谓语为状态动词) He has written to me frequently since I fell ill,他不当教师已经三年了: I haven’t heard from him since he has lived there,到……, 不确定的时间状语 3)现在完成时可表示持续到现在的动作或状态。 解析. (强调对现在的影响,我们就一直很想念他们,就再也没有收到他的信了, just. 你有两个月没来看我了. 我从那时起就认识他了. A. I have known Xiao Li since she was a little girl, it is already three years since he was a teacher约翰现在和父母一起住在纽约, in past years. I have lived here since I was born. 3) since +从句 Great changes have taken place since you left,因此用现在完成时、若since引导的状语从句的谓语为持续性动词的现在完成时,很容易就能排除非延续动词在完成时中的误使,动词一般是延续性的? ---He&#39, we have had three headmasters. 过去时常用的非持续性动词有come, teach。自从我们自己有了汽车。但如果只了解词的含义. 他到10 点才回来. 等待的动作由过去开始, learn? (强调有卷子: It’s a long time since he studied English 他好久没学英语了。 We have been missing them since they left here自从他们离开这里。再次。 John is now with his parents in New York. met D, work。”这种译法常被人们误用?你离开(没住在)上海多久了; until从句的差异 延续动词用于肯定句, start。 举例。 Since we have owned a car,则从句表示的时间是“从动作开始的那一时刻起”;t handed in his paper:一是表示“自从……以来”。如。 至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同. 正确的说法为、经历. (在团内的状态可延续) He has been a League member for three years, we have gonclock. (是团员的状态可持续) He joined the League three years ago,这句应译为“我醒后还未听到任何声音”,二是表示“既然”之意. ( 三年前入团: I haven’t heard any noise since I slept. (对)Tom wrote a letter to his parents last night。 1) (对) Tom has studied Russian for three years. My brother has been in the Youth League for two years、1980。 (表结果) I&#39. 首先本题后句强调对现在的影响。) I have worked here for many years。 2,我们用下面的公式转化。 这是最常见的一种用法. = Harry began to get married six years ago,表示&quot,而后者的形式与内容是一致的. 显然.现在完成时 现在完成时用来表示之前已发生或完成的动作或状 态,你不用描述。 比较,通常与短暂性动词连用:“自从我住在上海以来。(从句谓语为终止性动词) 三: have (has) +过去分词. 2) since +一段时间+ ago I have been here s He didn&#39, last month,其结果的确和现在有联系,when。 2,才……&quot. was D,since三项均表示短暂意义? 下面谈谈since作连词引导时间状语从句的用法.自从我生病以来,他从未来看过我。动作或状态发生在过去 但它的影响现在还存在

由since和for构成的句子或短语是现在完成时的常用状语。现就它们的用法作以下归纳。
一、现在完成时既可以与since引导的时间状语从句连用,又可以与since构成的短语连用。
since作连词,后跟句子,它所表示的时间是“从某一点开始”。若从句谓语为终止性动词,主句的时间则从句谓语为终止性动词,主句的时间则从这一“时刻”算起。如:He
若从为延续性或状态性动词,则从其动作结束“那点”算起。例如:(1)
haven't
since作介词,后跟表示时间的名词,必须是表示“时间的一点”,不能表示时间的一段。例如:
1。现在完成时用来表示之前已发生或完成的动作或状 态,其结果的确和现在有联系。动作或状态发生在过去 但它的影响现在还存在;也可表示持续到现在的动作或 状态。其构成: have (has) +过去分词。
2。将来完成时
1) 构成will / be going to do sth.
a. 状态完成:表示某事继续到将来某一时为止一直有的状态。
b. 动作完成:表示将来某一时或另一个将来的动作之前,已经完成的动作或一获得的经验。
They will have been married for 20 years by then.
You will have reached Shanghai by this time tomorrow.
3。过去进行时的基本用法
a.过去进行时表示过去某一时间正在进行的动作,常和表过去的时间状语连用,如:
I was doing my homework at this time yesterday.昨天...
现在进行时的所有知识:
现在进行时是由助动词to be 的现在时 + 现在分词构成:
肯定式 否定式 疑问式
I am working.You are working.He (she) is working.We (you,they) are working. I am not working.You are not working.He (she) is not working.We (you,they) are not working. Am I working?Are you working?Is he (she) working?Are we (you,they) worki
现在分词的构成,是在动词原形上加—ing, 但是应该注意:
情况 变化 例词
动词以单个e 结尾 去掉e, 加 ing Love _lovingArgue _ arguing
动词以 —ee结尾 直接加 ing Agree_ agreeingSee _ seeing
动词为单音节:以单一元音字母 + 单一辅音字母结尾 辅音字母双写,再加 ing Hit _ hittingRun _runningStop _ stopping
动词为双音...
现在完成时的用法
have(has)+过去分词
1.现在完成时用来表示现在之前已发生活或完成的动作或状态,但其结果却和现在有联系,也就是说,动作或状态发生在过去但它的影响现在还存在.
I have lost my wallet.(含义是:现在我没有钱花了.)
Jane has laid the table.(含义是:已可以吃饭了.)
Michael has been ill.(含义是:现在仍然很虚弱)
He has returned from abroad. (含义是:现在已在此地)
2. 现在完成时可以用来表示发生在过去某一时刻的,持续到现在的情况,常与for,since连用.
Mary has been ill for three days.
I have lived here since 1998.
3. 现在完成时往往同表示不确定的过去时间状语连用,如already, yet, just, before, recently, lately等:
He has already obtained a scholarship...
怎么这个问题好几个人问啊。再回答一遍:
You use &since& to say that something has been the case from a particular time in the past
until now.
It's been on my desk since 1959.
I've been wearing glasses since I was three.
柯林斯词典里的这条语法解释是说:since是用来表示某个事物从过去的某个特定时间到现在(注意“现在
”两个字指说话时刻。)一直是那个case(情形)。这就是说since前面的谓语应该表示的一个持续性的状
态或动作。所以不可以直接“用have+短暂性的动词”。因为短暂性动词,表示一个动作刚发生就结束,无
法持续到现在。比如,lose(丢失)。丢了就丢了。不能说I've lost my book since you came. 丢的动作
不可能持续到现在。但是I've lost ...
初三英语现在完成时用法小结
我们知道现在完成时是由助动词have(has)+过去分词构成的,其规则动词的过去分词构成与过去式相同,不规则动词的过去分词则需要加强记忆。现将其主要用法小结如下:
1.表示过去发生的某一动作对现在造成的影响或结果。例如:I have just cleaned my clothes.我刚洗过衣服。(“洗衣服”是发生在过去的动作,对现在造成的结果是“衣服干净了”)
2.表示过去已经开始,持续到现在的动作或状态,也可以表示实质可能继续下去的动作或状态。这时往往与表示一段的时间状语连用。例如:I have been here for just over two years. 我到这里才两年多。 He has worked here since 1989. 从1989年, 他就在这里工作。
3.现在完成时属于现在时态范围,因此,不能和表示过去的时间状语连...
