of course 与surede的区别
of course 与surede的区别

certain与sure的区别英语中的sure和certain是近义形容词,均有“肯定的;确信的;有把握的”的意思,它们的用法也大体相似,许多情况下可以通用,但它们之间也有一些差别,现归纳如下:一、相同点

1.两者都能用于“be sure/certain + about /of短语”句型中,表示“对(某事)有把握”。主语必须是人,about/of之后多跟名词、代词。如:I am sure/certain of his returning. 我确信他会回来。He is quite sure/certain of /about it. 他对这事很有把握。

2. 两者都能用于be sure/certain to do sth句型中,表示“一定会做某事”,主语可以是人,也可以是物。如:Spring is sure/certain to follow winter. 冬天过后一定是春天。They are sure/certain to come. 他们一定会来的。

3. 两者都能用于“be sure/certain +从句”句型中,表示“确信……”,主语只能是人,而不能是物。如:Tom is sure/certain that I put the key on the table. 汤姆确信我把钥匙放在桌子上了。We are sure/certain that the book will be of great help to us.我们相信这本书对我们会有很大帮助。

4.两者都能用于“make sure/certain +从句”结构中,表示“确定;弄清楚”,主语只能是人。如:You must make sure/certain when the bus will leave. 你必须弄清汽车何时出发。

5.“I ' m not sure…”与“I ' m not certain…”意思相同。如:I ' m not sure/certain where he is. 我不能确定他在哪儿。I ' m not sure/certain how to do it. 我不能确定如何做这件事。

二、不同点

1. “I ' m sure…”与“I ' m certain…”均可译为“我深信(确)信……”,但两者的含义却不同。前者表示一种主观上的判断或感觉,事实并不一定如此。后者强调的则是客观事实,意为主语已经知道后面的内容是既定的事实。试比较下面一组句子:I ' m sure he didn ' t steal it. He isn ' t that kind of person. 我确信他没偷,他不是那种人。I ' m certain he didn ' t break the cup.

I broke it myself. 我敢肯定他没有打碎那个茶杯,(因为)那个茶杯是我打碎的。

2. 如果it作为形式主语代替从句时,则其后的表语用certain,而不能用sure。如:It isn ' t certain whether he will give us a report next Monday. 下星期一他是否来为我们作报告还不能确定。

3.两者在作定语时含义不同:sure意为“可靠的;无误的”;而certain若修饰可数名词,意为“某一;某些;某种;一些”,若修饰抽象名词,表示程度,意为“有点;有些”。如:The letter was sent by a sure hand. 信已由一位可靠的人寄出了。He made a sure answer. 他回答得准确无误。A certain person called on me yesterday. 昨天有个人来找过我。

4.在祈使句中常用sure,不宜用certain。如:Be sure and remember what I told you. 千万要记住我对你讲的话。Be sure to write and tell me all the good news. 务必写信告诉我所有的好消息。

5. 口语中,sure常作副词,用在肯定答语中替代surely,这时与of course,certainly意思相当,而certain不可作副词用。如:—Would you please turn down the radio a little bit? 请你把收音机音量拧小点,好吗?—Sure/of course/certainly. 当然可以。certainly与surely用法比较区别一表示客观论断,意为“无疑地”、“肯定地”、“确实地”,两者常可换用(注:通常用于被修饰词语之前)。如:He will surely [certainly] fail. 他肯定会失败。The results are surely [certainly] satisfactory. 结果确实令人满意。区别二表示主观看法, 意为“想必”、“一定”、“我相信”等义,通常只用surely。此时它表示既相信又不肯定或感到惊讶(有时几乎相当于一疑问句,书写时可用问号),通常置于句首或句末,若主语是人称代词,有时也可紧跟在主语

之后。如:You can do something to help him, surely. 你总可以想点办法帮他一下吧。Surely that?s Jim over there? I thought he was in Paris. 那边想必是吉姆吧? 我还以为他在巴黎呢! You surely [Surely you] don?t believe that. 想必你不会相信那种话吧。比较:That?s certainly a plain-clothes policeman. 那肯定是个便衣警察。(表客观论断) Surely that?s a plain-clothes policeman. 那一定是个便衣警察吧。(表示主观看法) 注:若用于否定句,则更强调说话者的怀疑态度,可译为“不见得会”、“不一定会”。如:Surely you are not going alone. 你不见得会一个人去吧!of course 一定,当然=without doubt of course在口语中的用法表示:当然;自然。如:He was late again,of course. 自然他又迟到了。Of course I…ll help you. 我当然会帮你。Of course,I wish both of you well. 当然我希望你们俩身体健康。He was joking. Of course I…m not a poet. 他是在开玩笑,我当然不是诗人。通常在对话中用作回答。如:A:Are you coming with us?你和我们一起去吗?B:Of course. 当然啦。A:Will you be able to come to the meeting?你能来开会吗?B:Of course. 当然能来。A:May I book your dictionary?我可借你的字典吗?B:Yes,of course. 当然可以。有时与not连用。如:A:Were you glad to leave?你愿意离开吗?B:Of course not. 当然不愿意。A:Do you want lost the game?你起输掉这场比赛吗?B:Of course not. 当然不想

介词on 和about的辨析

we shall be pleased to send you the necessary information___ our machine tools. 为什么选择on而不是about? 简单区分,about通俗大众;on学术【专业】性强 on与about 二者都是介词,意为“关于,论及”等,一般情况下,二者可以互相替换,但二者有点区别:about常用于简单的或浅显的论述等,是一般用语,多用于讲故事,谈话;思考等; on多用于系统论述或专题讲演、论著等,具有学术性,如:The teacher told us a story about Lei Feng. It's very moving. He will give us a talk on the history of the Party.他将给我们做个关于党史的报告。 正误例析今天下午我们将听一个关于非洲历史的演讲。 误:We're going to listen to a lecture about African history his afternoon. 正:We're going to listen to a lecture on African history this afternoon. 析:介词about和on都可以作“关于”解。on表示一本书、文章或演讲是严肃的、学术性的,可供专门研究这一问题的人们参考;about则表示其内容比较通俗,一般人都可阅读。 on多用于较严肃的或有关学术的场合,也表示关于某人或某事物的详情,常与talk,speak,report,lecture等词连用。 about常用于比较一般和随便的场合,表示关于某人或某事的详情,常与talk,speak, tell, hear,write, read,think等词连用。 about 的意义更广泛,on表示“关于。。。”通常只表示关于某学科,论题等如:We need to write an essay on this issue. 我们需要写一篇关于这个议题的论文。 This is an artical on biology。这是一篇关于生物学的文章。 这些用法在不正规场合,如口语中,可以用about代替,意思不变。 但about可以表示关于任何东西。

be about to的含义及其用法

be about to do: 1) 表示即将发生的动作,在时间上指最近的将来。如: We are about to start. 我们就要出发了。 The new school year is about to begin. 新学年开学在即。 2) 在含有be about to do的句子中,不能再加时间状语。如:Wrong: The medical team is about to start immediately. Right: The medical team is about to start. 医疗队就要出发了。 附:be to do 用法的详细讲解: 一般说来,“be to do”这个结构有两种语法意义,其一是连系动词be+动词不定式做表语,其二是be to是一个独立词汇单位,具有情态含义,可以把它叫做情态习语(modal idiom)。 一、be +动词不定式, 不定式做表语,表示主语和表语在概念上是等同的。如: The problem is to find a solution. His plan is to clean the room. My wish is to be a doctor. 二、be to +动词不定式中的be to用作情态习语, 这时的be to do表示: “计划”、“安排”、“义务”、“应该”、“可能”、“命运”等。(have to, ought to)。如: He is to have a holiday. (表示将来) The committee is to meet today. (表示计划、安排)

You are to go to the hotel where rooms have already been booked for you. 1. 表示“将”、“计划”、“安排”。(意思接近于be going to) 如:Their daughter is to get married soon. Who is to question him? It was the last film at the cinema,which was to close next day. After dinner they were to go to a movie. was/ were to do 表示过去曾经计划要做的事,或者过去应当做的事,而且从现在的角度来看已经实现了。如: I felt nervous because I was soon to leave home for the first time. I was to play Juliet. The expedition was to start in a week’s time. was/ were to have done, 表示“本打算”、“本计划”或“本应当”做的事而没有做成或没有发生。如: I was to have seen him last Wednesday, but he didn’t come. We were to have been married last year. 2. 表示“义务”、“应该”。(意思接近于should, must, ought to, have to) 如: No one is to leave the building. 谁也不得离开这楼房。 You are not to smoke in this room.=You are not supposed to smoke in this room.

to和for的用法有什么不同(一)

to和for的用法有什么不同(一) 一、引出间接宾语时的区别 两者都可以引出间接宾语,但要根据不同的动词分别选用介词to 或for,具体应注意以下三种情况: 1. 在give, pass, hand, lend, send, tell, bring, show, pay, read, return, write, offer, teach, throw 等之后接介词to。如: 请把那本字典递给我。 正:Please hand me that dictionary. 正:Please hand that dictionary to me. 她去年教我们的音乐。 正:She taught us music last year. 正:She taught music to us last year. 2. 在buy, make, get, order, cook, sing, fetch, play, find, paint, choose, prepare, spare 等之后用介词for 。如: 他为我们唱了首英语歌。 正:He sang us an English song. 正:He sang an English song for us. 请帮我把钥匙找到。 正:Please find me the keys. 正:Please find the keys for me. 能耽搁你几分钟吗(即你能为我抽出几分钟吗)? 正:Can you spare me a few minutes?

正:Can you spare a few minutes for me? 3. 有的动词由于用法和含义不同,用介词to 或for 都是可能的。如: do sb a favor=do a favor for sb 帮某人的忙 do sb harm=do harm to sb 对某人有害 在有的情况下,可能既不用for 也不用to,而用其他的介词。如: play sb a trick=play a trick on sb 作弄某人 请比较: play sb some folk songs=play some folk songs for sb 给某人演奏民歌 有时同一个动词,由于用法不同,所搭配的介词也可能不同,如leave sbsth 这一结构,若表示一般意义的为某人留下某物,则用介词for 引出间接宾语,即说leave sth for sb;若表示某人死后遗留下某物,则用介词to 引出间接宾语,即说leave sth to sb。如: Would you like to leave him a message? / Would you like to leave a message for him? 你要不要给他留个话? Her father left her a large fortune. / Her father left a large fortune to her. 她父亲死后给她留下了一大笔财产。 二、表示目标或方向的区别 两者均可表示目标、目的地、方向等,此时也要根据不同动词分别对待。如: 1. 在come, go, walk, move, fly, ride, drive, march, return 等动词之后通常用介词to 表示目标或目的地。如: He has gone to Shanghai. 他到上海去了。 They walked to a river. 他们走到一条河边。
