announce和declare的用法

announce和declare的用法
announce和declare的用法

announce更接近于汉语“公布”、“告知”的意思,它所涉及的是一件对方原来不知道的事。如:The accident was announced to his family by telephone. 已将事故用电话告诉了他的家属。The date of his visit has not been announced. 他来访的日期尚未公布。declare含有庄严宣告或交代清楚的意思,它所涉及的事不一定是对方所不知道的。如:The accused declared himself to be innocent. 被告宣称自己无罪。Fighting has been going on for a year, but war has not yet been declared. 仗已打了一年,但并没有宣战。以上各句中的announce 与declare不可互换。但有时两个词用在同一句中都说得通。如:The government announced ( declared ) the danger to be past. 政府宣布危险已经过去。

“declare”有一种很常见的用法可以归纳为如下公式:

declare + sth/sb + (to be) adj/noun (其中括号内的内容可省略,adj表示形容词,noun表示名词)

The leader declared the meeting (to be) open. (to be可以省略)

领导宣布会议开始。

又比如:

The chairman declared this meeting (to be) closed.

主席宣告散会。

而“announce”则没有这种用法(上述的那个公式);

declare还含有"正式地,来自官方"的意思。比方说"宣战"就得用declare,宣布会议、仪式、典礼等开始或结束也用declare,如果宣布获奖名单什么的annouced 和declare 都可以。

语法上来讲,announce后面只能接名词和从句作宾语。而declare 不仅可以接名词和从句作宾语,也接“宾语+名词/形容词”的结构,The leader decalred the meeting open就是这种句型,announce不能用这种句型。

感官动词用法 Prepared on 22 November 2020

“感官”动词用法小结 我们学过了五个与人的感觉有关的动词,它们是look,sound,smel l,taste,feel,我们可称之为“感官”动词。它们的用法有着许多相同点,但也有不同之处,现就此作一小结。 一、这五个动词均可作连系动词,后面接形容词作表语,说明主语所处的状态。其意思分别为“看/听/闻/尝/摸起来……”。除look 之外,其它几个动词的主语往往是物,而不是人。例如:These flowers smell very sweet. 这些花闻起来很香。 The tomatoes feel very soft. 这些西红柿摸起来很软。 The music sounds beautiful. 二、这些动词后面也可接介词like短语,like后面常用名词。例如: Her idea sounds like fun. 她的主意听起来很有趣。 He looks like his father. 三、这五个感官动词也可作实义动词,除look(当“看起来……”讲时)只能作不及物动词外,其余四个既可作及物动词也可作不及物动词,其主语通常是人。例如:

She smelt the meat. 她闻了闻那块肉。 I felt in my pocket for cigarettes. 我用手在口袋里摸香烟。 He tasted the soup and added some salt. Miss Wang asked us to look at the blackboard. 四、taste,smell作不及物动词时,可用于“taste / smell + of + 名词”结构,意为“有……味道 / 气味”。例如: The air in the room smells of earth. 房间里的空气有股泥土味。 The bread taste of sugar. 五、它们(sound除外)可以直接作名词,与have或take构成短语。例如: May I have a taste of the mooncakes 我可以尝一口这月饼吗 May I have a look at your photo 六、其中look,sound,feel还能构成“look / sound / feel + as if +从句”结构,意为“看起来/听起来/ 感觉好像……”。例如: It looks as if our class is going to win. 看来好像我们班要获胜了 It sounds as if the rain is very heavy.

because,since,as,for的用法区别

because、since、as、for的用法区别 because、since、as、for这几个词都是表示“原因”的连词,语气由强至弱依次为:because→since→as→for。其中because、since和as均为从属连词,引导原因状语从句;而for是并列连词,引导并列句。 ?because because表示直接原因,它所指的原因通常是听话人所不知道的,其语气最强。常用来回答why的提问,一般放在主句之后,也可以单独存在例如: (1)Istayed at home because it rained. 因为下雨,我呆在家里。 (2)B ecause Lingling was ill, she didn’t come to school. 玲玲因为生病,没有上学。 (3)—Why is she absent? 她为什么缺席? —Because she is sick. 因为她病了。 (4)此外,在强调句型中只能用because。例如, It was because I missed the early bus that I was late for school. 我上学迟到是因为我错过了早班车。 ?since since侧重主句,从句表示显然的或已为人所知的理由,常译为“因为、既然”,语气比because稍弱,通常置于句首,表示一种含有勉强语气的原因。例如: (1)Si nce he asks you, you’ll tell him why. 他既然问你了,那就告诉他为什么吧。 (2)Si nce everyone is here, let’s start. 既然大家都到齐了,我们就是出发吧。 (3)Since I understood very little Japanese, I c ouldn’t follow the conversation. 我日语懂得不多,因而听不懂对话。 ?as as是常用词,它表示的“原因”是双方已知的事实或显而易见的原因,由于理由不是很重要,含义与since相同,但语气更弱,没有since正式,常译为“由于,鉴于”。从句说明原因,主句说明结果,主从并重。例如:

中考英语:since与for用法

现在完成时态中的since 与for 1. 实例: We have studied English for more than 2 years. 我们学英语已有两年多时间了。 She has been ill since last Sunday. 她从上周星期天一直病到现在。 2. 用法说明: (1) 介词for 短语表示一个时间段,指某个动作或情况到现在为止已持续了多久,提问时用how long;since 作为介词,接一个时间名词,作为连词,引导一个时间状语从句(从句动词一般是短暂性动词),since 表示“自…以来”,指某个动作或情况从过去某一点时间一直持续到现在,因此,与for 或since 引出的时间状语连用的句子(或主语)谓语动词必须是持续性的(如上面两句中的动词study 和be) (2) 英语中有些动词的意义不能持续,表示的是一瞬间就结束的动作,这些动词被称为非持续性动词或短暂性动词,常见的如come, leave, go, lose, see, begin, start, arrive, bec ome, die, buy, borrow, close, join, reach, fall, get up 等。这类动词可以用于完成时态,但在肯定句中不能与表示动作延续的时间状语for 或since 短语连用。如:正:He has come back. 他已回来。 误:He has come back for three days. 若要表示“他回来已三天了”这样的意思,可以将动词改为延续性动词,或改变时间状语,或改用别的句型等,如译为: He has been back for three days. (改变谓语动词) He has been back since three days ago. (改变谓语动词) He came back three days ago. (改变时间状语及动词时态) It’s three days since he came back. (改变句型) (3) 非持续性动词用于完成时态,在肯定句中不能与for 或since引出的短语(或句子)连用,但在否定句中是可以的,因为一个非延续性动词一旦被否定即成为状态,而状态总是可以延续的。如:(https://www.sodocs.net/doc/1711585746.html,) I haven’t seen him for a long time. 我很久没见到他了。 He hasn’t come here for some time. 他有段时间没来了。 I haven’t heard from her since she left. 自他离开以后,我一直没收到她的来信。

It's too dangerous. 她告诉我不要快骑自行车,那太危险了。 Please tell me something about yourself.请告诉我关于你自己的一些事情。 3、speak的意思是“说话”,作不及物动词时,通常指说话的能力和方

式;作及物动词时,其后的宾语为某种语言。speak to sb.表示“同某人说话”。 eg. Would you like to speak at the meeting? 你要在会上发言吗? Bob speaks Chinese quite well. 鲍勃汉语说得相当好。 Joe can speak a little Chinese. 乔能说一点儿汉语。 May I speak to Mr. Green? 我可以同格林先生通话吗?

tell地用法和常见搭配

tell的用法和常见搭配 tell的中文含义是:说;告诉;讲述。 例句:Tell him to wait for a few minutes, please. 请告诉他等几分钟。 tell一般用作及物动词,常用于tell somebody to do something这个结构中,表示“要某人做某事”,如:Tell the kids to be quite, please. 请告诉孩子们保持安静。类似的结构还有ask somebody to do something。 tell还常用于tell somebody something和tell somebody about something这两个结构中。两个结构都有“告诉”的意思,它们的区别是:tell somebody something告诉某人某事(往往是不需要解释、说明的事);tell somebody about something向某人讲述某事(往往含有解释、说明的意味)。试比较: Tell me your phone number. 告诉我你的。 Please tell me something about your school life. 请给我讲讲你的校园生活吧。 常用搭配: tell somebody to do something 告诉某人去做某事 tell somebody something 告诉某人某事 tell somebody about something 向某人讲述某事 speak, talk, say, tell的用法区别 这四个词的用法辨析是中考英语中考得最经常的同义词辨析之一。综观各省市的中考英语真题情况,我们发现,中考对这四个词的考查主要侧重于其用法差异和习惯表达方面的不同。因此,本文拟在这两个方面谈谈它们的具体用法和区别。 一、用法方面的区别 1.speak 强调单方的“说”或“讲”,一般用作不及物动词,要表示“对某人说(某事)”,可用 speak to [with] sb (about sth)。如: Please speak more slowly. 请说慢一点。 I spoke to [with] the chairman about my idea. 我跟主席说了我的想法。
