more than 的用法

简简单单的“more than”,用法可多呢!

more than的常见用法如下:

1) 后跟名词,表示“不只,不仅仅,甚于”;

2) 后跟数词,表示“……以上,多于……,……有余”;

3) 后跟形容词或副词,在语义上表示很高的程度,常常译为“非常,十分,更加”。

Napoleon, as a character in Tolstoy’s War and Peace, is more than once described as having “fat little hands.”

下面是些好例子:

● A. “More than+名词”表示“多于……”、“非但……尤其是”如:

1)Modern science is more than a large amount of information.

2)Jason is more than a lecturer; he is a writer, too.

● B. “More than+数词”含“以上”或“不止”之意,如:

3)I have known David for more than 20 years.

4)Let's carry out the test with more than the sample copy.

● C. “More than+形容词”等于“很”或“非常”的意思,如:

5)In doing scientific experiments, one must be more than careful with the instruments.

6)I assure you I am more than glad to help you.

● D. 在“More...than...”中,肯定“more”后面的而否定“than”后面的,约等于“是……而不是……”如:

7)The difference between pure linguistics and applied linguistics is more apparent than real.

8)This book seems to be more a manual than a text.

9)Catherine is more diligent than intelli-gent.

10)Hearing the loud noise, the boy was more surprised than frightened.

● E. “More than”或“More...than...”+含“can”的分句时表示“否定意”,如:

11)That's more than I can do.

12)Don't bite off more than you can chew.

13)In delivering his lecture, Jason makes sure not to include more things than the students can understand.

● F. “No more...than...”表示“不……;不如……”,如:

14)I can no more do that than anyone else.

15) A learner can no more obtain knowledge without reading than a farmer can get good harvest without ploug hing.”

“No more…...than...”的语义,也可用“not any more than...”来取代,因此15 可以变成16。

16) A learner cannot... any more than ...”同样的,17可以变成18:

17)Dr Hu is no more a poet than Dr Wu is a philosopher.

18)Dr Hu is not a poet any more than Dr Wu is a philosopher.

此外,“more than”也在一些惯用语中出现,如:

19)More offen than not (经常),people tend to pay attention to what they can take rather than what they can give.

20)All of us are more than a little concerned about(非常关心)the current economic problems.

总之,“more than”看似简单,其实很有内涵,味道隽永

no more than /not more than

在数量上进行比较时,no more than = only, 意为“仅仅,只有”;

not more than=at most, 意为“至少,不超过”。例如:

There are no more than ten people in the room. 房间里只有十个人。

I have not more than 20 books.我最多有20本书。

在程度上进行比较时,no more than有“两者都不”之意,表示说话者主观上嫌其少(差、不足、不好)等;not more than含有“不及、不多于”之意。只反映实际情况,无任何语气。

This book is no more interesting than that one.这本书并不比那本书有趣。

This story is not more interesting than that one.这个故事不如那个故事有趣。more than: 除了有“多于”的意思外,还有“不只,不仅”的意思。例如:

[例句]

He is more than kind.

他不只是仁慈而已。

英语中more than 的用法比较复杂,它除了用于比较结构外,还可以与名词、形容词、动词或从句等连用,表达不同的含义。下面是more than 结构的一些常见用法

1. more than 结构后跟名词表示“不只是”;“不仅仅”等。例如:

(1) However, we must consider more than the beginning of the motion.

然而,我们必须考虑的不只是运动的初始阶段。

(2) Peace is more than the absence of war.

和平不只是意味着没有战争。

2.more than 用来修饰形容词、分词和动词,表示所修饰的词份量不重或含义不够,而加以说明,译成汉语可为“非常”,相当于“very”或“much”。例如:

(1) He is more than selfish.

他非常自私。

(2) He is more than happy about it.

他对此事极为高兴。

(3) I am sure conditions over there will more than satisfy your requirements.

我相信那边的条件会极大地满足你的要求。

3.more than 后接单数名词,谓语动词用单数。例如:

(1) More than one person has been concerned in this.

这里涉及的不止是一个人。

(2) More than one member protested against the proposal.

不止一个成员反对这个建议。

4. more A than B 结构。用来比较两种说法的正确程度,即前一种说法(A 项)比后一种说法(B项)要正确一些,表示“与其……不如……”。在这个句型里,more 后不能用形容词或副词的比较级形式,而要用原级形式,此外还可用名词、代词、动词、介词短语等。例如:

(1) He is more good than bad.

与其说他坏不如说他好。

(2) It is more a poem than a picture.

与其说这是一幅画,不如说这是一首诗。

5. more than 或more... than 后接从句,可表示否定意义。例如:

(1) The beauty of Hangzhou is more than words can describe.

杭州景色之美是说言所不能描述的。

(2) That is more than I can tell you,sir.

这一点我是不能告诉你的,先生。

(注意:在这种句型中,more than 后常接含有can 或could 的从句,表示“……不能”。)

对于下列表示否定意义的句子,有的语法学家认为在than 后面省略了when,有的认为省掉了it,也有的认为than 用作关系代词,因而并无省略。这类句子在理解上并不困难,结构上变化也不大,从实用出发,可将其视为一种句型来学习。例如:

a. You spent more money than was intended to be spent.

你花掉的钱比原计划的要多。(原计划要花的钱没有这么多。)

b. This is more money than is needed.

这笔钱比需要的多。(需要的钱没有这么多。)

c. We often advise him not to drink more wine than is good for his health.

我经常建议他不要饮酒太多,以免有害健康。

6. more than 结构可以由far,much,a little,slightly,hardly,nothing,no 等词修饰,一般置于more than 结构前。例如:

(1) This little man was hardly more than one meter fifty tall.

这个小个子男人身高仅1.5米。

(2) She could have thought of nothing more likely to please her brother than this praise of Maggie.

她本该想到没有比赞扬玛琪更能使她哥哥高兴的了。

(在这里,nothing more ... than 表示最高级的意思。)

学法用法工作总结

学法用法工作总结 学法用法工作总结(一) 加强依法治校,全面提高师生法制意识和学法用法自觉性是学校一项重要战略任务。近年来,我校坚持组织领导、建章立制、课内与课外、校内与校外相结合,将普法依法治理工作纳入学校重要议事日程,普法经费足额到位;结合实际,有针对性地开展学法用法活动,保证和促进了学校法制教育走上规范的管理和依法运行的轨道。 一、加强领导,形成依法治校的工作机制 组织建设是开展依法治校工作的根本保证。学校成立依法治校领导小组,由校长、党支部书记任组长,德育副校长、法制副校长任副组长,政教处、教务处、总务处、保卫科、团委负责人为成员,学校与交警队、消防队、派出所等单位建立了共建关系,保卫科负责具体抓落实工作,把依法治校工作摆上重要议事日程,做到依法治校工作与学校各项工作同计划、同实施,并把目标任务分解到各个处,确保依法治校工作齐抓、共管,各司其职、各负其责,层层抓落实的工作格局。 二、建章立制,确保依法治校的顺利实施 建章立制是落实依法治校的具体措施,依照宪法、法律、法规和规章结合学校实际情况,我校制定了一系列规章制度,如各处室管理制度、教职员工考核奖惩制度、德育规章制度等,保证学校各部门、各岗位工作有序高效运作,使学校法制管理走上了规范化、制度化轨

道。此外,学校通过板报、标语、横幅、集会、校园网、家校短信平台等形式,向全体师生和广大家长广泛宣传,在校报《校园之声》和校园广播《青春之音》上开辟专栏,进行宣传。通过广泛宣传,使“法律进校园”活动深入人心,增强了师生学法、守法的积极性和自觉性。 三、推进依法治教,构建法制校园。 我们开展“法律进校园”活动作为把依法治教、依法治校的前提,不断加大工作力度,积极实施,稳步推进。一是建立完善学校学法用法工作制度;二是加强学校领导、教职工的普法学法工作,号召全体教师自觉学法律、讲权利、讲义务、讲责任,进一步增强法制观念和法律素质。组织广大教师深入学习《宪法》、《教育法》、《教师法》、《刑法》、《治安管理处罚法》、《道路交通安全法》、《食品卫生法》等,在学法、用法和守法、护法中发挥表率作用。三是进一步建立健全符合法律法规、工作条例的学校管理制度,形成具有法治理念的校园秩序和文化氛围,使学校成为学生参与法治实践,培养法制观念,提高法制素质的重要场所。学校将管理制度汇编成册,装订成书,教师人手一册,加强了制度管理的透明度和执行的自觉性。 四、加强法制教育,普及法律知识。 1、立足课堂,充分发挥青少年法制教育主渠道作用。

morethan的详细用法

一、 more than 1. more than 可放在数词之前,意为“超过;不止;以上”,用于此意义时可与 over 互换使用。例如: Altogether more than 70 percent of the surface of our planet is covered by water. 整体说来,我们这个星球表面有 70% 以上都为水所覆盖。 2. more than 可放在名词之前,表示“不只是;不仅仅”。例如: Hibernation is more than sleep. 冬眠不仅仅是睡眠。 Bamboo is used for more than building. 竹子不只是用于建筑。 3. more than 用于形容词或副词前,作“非常;十分”解,与 very 同义。例如: She is more than careful in doing things. 她做事非常细心。 In class, he listens more than attentively. 在课堂上,他听讲十分认真。 4. more than 之后接含有 can 的从句时,常表示否定意义。此时,从句中的谓语动词必须是及物动词,并且与句子的主语呈现逻辑上的动宾关系。例如: This secret is more than we can let out. 这个秘密我们是不能泄露的。(主语 secret 是 let out 的逻辑宾语) 比较:less than 后面接形容词、副词时,意为“不;很少;不到”,具有否定意义。例如: a) We were busy and less than delighted to have company that day. 那天我们很忙,不高兴有客人来。 b) The young man is less than twenty years old. 这个年轻人不到 20 岁。 二、more … than 1. more … than 意为“与其……不如……”;“是……而不是……”,常可与“ rather than ”或“ not so much … as”互换使用。例如: He is more like a spear than anything else. = He is like a spear rather than anything else. = He is not so much like anything else as like a spear.

红景天的用法总结

红景天用法汇总 1. 简介 红景天是历朝历代帝王延寿抗衰老的首选之品,也是各朝名医心领神仪的名贵药材。红景天生长在深山大川、悬崖峭壁之上,红景天的足迹往往在人迹罕见的冰川脚下、在白雪覆盖的林海深处,红景天几乎统治了2000公尺雪线生长带,以其生命不衰的顽强生存意识,成为历代皇家御用药材。据《神农本草经》(2200年)记载红景天被列为上品:“主大热生疮、身热烦、邪恶气”。红景天含有具有生物活性的微量元素钙、镁、铁、铅、锌、银、钴、镉、钼、钛、镭等21种。还有人体所需要的十几种氨基酸,其中几种是人体必须的而体内有不能合成的氨基酸,含有丰富的维生素。 2. 食用方法 每日用量:保健3g,治病6g-12g(仅作参考)。 服法:泡开水当茶喝。红景天性寒多服也不会造热生火,且消炎清热,可常年服用。 1)活血消肿:红景天(泡高度白酒) 2)美容润肤:红景天(熬汤汁)+牛奶(敷脸) 3)抗疲劳、抗高原反应:红景天(泡水当茶) 3. 红景天功效1 具有抗缺氧、抗寒冷、抗疲劳、抗微波辐射、抗毒、抗瘟疫、双向调解功能。其具有提高工作效率,补充心脑血氧浓度、抗氧化,延缓人体细胞介质水渗透互换,改善微循环作用,大量增加抗体,提高免疫力,使之延缓衰老,防治老年疾病等功能。 1)抗缺氧作用:红景天可增强人体对缺氧的耐受性,降低氧耗量,同时又加大动脉氧压差,提高氧的利用率,保护肌体脏器官在低氧环境中不受损害,使细胞代谢旺盛。 2)抗疲劳作用:功效类似人参,可明显提高运动员的无氧阀,降低心肌和脑组织的血乳酸值,加快清除疲劳,恢复体力,可提高运动成绩和人们的工作效率,增强记忆能力。 3)双向调节作用:能使“亢进”的功能下降,也能使衰弱的肌体兴奋,从正负两方面使肌体趋向正常。对糖尿病、甲亢、甲低,高低血压病有明显的治疗作用,对高血压患者的降压作用优于复方降压片。 4)活血化淤作用:防止缺氧使血液流变的发生“粘、浓、聚”变化形成血栓,还可用于妇女月经不调、红崩、白带,外用止血消肿等。 5)抗病毒作用:能阻止病毒颗粒的吸附,保护细胞不受病毒的损害,并有一定抑制病毒的作用。 6)抗衰老悦颜健美作用:能消除自由基能力,阻止过氧化反应,抑制此处褐素形成和堆积,从而提高细胞生命力,延缓细胞衰老。 7)抗幅射、抗癌作用:抑制癌细胞,减轻化疗、放疗的副作用。 8)提气升阳,清音利喉作用:慢性咽炎成了歌唱家、教师、公务人员的顽症,泡水常服可消除顽疾。 4. 红景天功效2 红景天可以补气清肺;健脾益气,活血化瘀、益智养心;收涩止血;散瘀消肿。主要针对气虚体弱;病后畏寒;气短乏力;肺热咳嗽;咯血;白带腹泻;跌打损伤;烫火伤;神经症;高原反应等症状。 红景天可以泡水喝,不过这样红景天中的有效成分不能够充分的溶解到水中。相比之下,煎煮会好些,一般先将红景天浸泡3到4个小时,然后用小火煎煮40分钟,让红景天中的有效成分能够溶解出来。当然还有红景天胶囊,提取出来的红景天,更能够容易被人体吸收。.红景天,藏语名:苏罗玛保。在民间被喻为“长生不老草”和“九死还魂草”。盛产于青藏高原,生长在海拔3500—5000米的高寒地段,在缺氧、低温、干燥、狂风、强紫外线辐射的恶劣环境里具有极强的生命力。
