英语opposite reaction 的意思是相反的反应

帮你百度了一下，好像是个新杂志刊号。

modify的名词形式：改进；修改；改变

考察dynamic和dynamical的区别，我发现原来很多人也搞不清楚，而在词典中，这两个词经常是混用的。当然Dynamic还可以是一个名词而Dynamical只能是一个形容词。Dynamic做名词时，其实就是dynamics的单数形式，表示一种基本的或动态的力，特别是那种导致、促进或影响发育、发展或稳定性的力。

mass是质量

negotiate的名词是negotiation。negotiation读音：英［nu026au02ccɡu0259u028au0283iu02c8eu026au0283n]，美［nu026au02ccɡou028au0283iu02c8eu026au0283n]。释义：n.谈判；转让；顺利的通过。例句：The negotiation of lease rights is still under discussion.租赁权的转让问题还在讨论中。复数：negotiations。短语：negotiation date议付日期。restricted negotiation限制议付。negotiation element协商单元。negotiation的近义词mediation读音：英［u02ccmiu02d0diu02c8eu026au0283n]，美［u02ccmiu02d0diu02c8eu026au0283n]。释义：n. 仲裁；调停，居中调停；调解。例句：There are certainly a number of different types of mediation and arbitration types of scenarios available to you.你们肯定会找到几种解决和仲裁方式。形容词：mediative。短语：verbal mediation言语中介。chemical mediation [医］化学间介作用。mediation board调解委员会。

other及其变化形式很多，有以下几种：the other, others, the others, another 等。它们的用法现归纳如下；1.other可作形容词或代词，做形容词时，意思是“别的，其他”，泛指“其他的（人或物）”。如： Do you have any other question(s)? 你还有其他问题吗？ Ask some other people. 问问别人吧！ Put it in your other hand. 把它放在你另一只手里。 2.the other指两个人或物中的一个时，只能用the other，不能用another，此时的other作代词。如： He has two daughters. One is a nurse, the other is a worker. 他有两个女儿，一个是护士，另一个是工人。 the other后可加单数名词，也可加复数名词，此时的other作形容词。如： On the other side of the street，there is a tall tree. 在街道的另一边，有一棵大树。 Mary is much taller than the other girls. 玛丽比其他的女孩高得多。 He lives on the other side of the river. 他住在河的对岸。 3.others是other的复数形式，泛指“另外几个”，“其余的”。在句中可作主语、宾语。如： Some of us like singing and dancing, others go in for sports. 我们一些人喜欢唱歌和跳舞，其余的从事体育活动。 Give me some others, please. 请给我别的东西吧！ There are no others. 没有别的了。 4.the others意思是“其他东西，其余的人”。特指某一范围内的“其他的（人或物）”。是the other的复数形式。如： Two boys will go to the zoo, and the others will stay at home. 两个男孩将去动物园，其余的留在家里。 the others=the other +复数名词，这在第2条中已经有所介绍。希望对你有所帮助，呵呵。

可数

other,不单独使用,常与复数名词连用,表示 其他的(人或物)例:Ask some other people. 问其他人吧泛指别的人或物时,用others 也在一定范围内,但不是全部例:Some are in the classroom ,others are on the playground after class. 课后,一些学生在教师里,另一些在操场上.

1. 主语单一原则 主语单一指的是句子中必须有主语，而且必须唯一，这一原则在主句和从句中都是适用的。 例1.____in the desert is mainly due to the limited supply of desert water. (a) plants are widely spaced (b) the spacing of plants is wide (c) plants to be spaced widely (d) the wide spacing of plants （01/99 12） key： d 分析：空格后的介词短语不能做主语，判断它是主语的修饰语，而空格处应填入主语。（d）中的名词短语做主语，正确。 2. 谓语单一原则 例2.experiments related to the sense of smell are more easilyer_____than those related to perception of color. (a) setting them up (b) to set up (c) set up (d) set up those (01/97 14) key：c 分析：主句谓语动词是被动语态，easily是副词，修饰set up。（注意，在考试中还有一个经常考的考点是主语 + 系动词 + 不定式表示被动意义，如the book is easy to read. “easy” 是形容词，所以后面用不定式。 3. 主谓结构 例3. copper_____used by humans and is second only to iron in its utility through the ages. (a) the first metal (b) was the first metal (c) the first metal that (d) being the first metal (10/98 7) key：b 分析：由and连接的并列的句子可以看出，前面应该是一完整的句子结构，现在缺少谓语成份。只有(b)有谓语动词was。used by humans过去分词做定语修饰metal。 4. 宾语成份 。常考类型包括：及物动词后的宾语成份，激磁后需加的宾语成份，某些词或词组带双宾语的固定用法。 例4.formerly called natural philosophy,physics has retained_____of understanding the structure of the nature world and explaining natural phenomena. (a) its original aim (b) it aimed originally (c) its original aim was (d) aiming originally （10/98 3） key：a 分析：主语缺少宾语，只有(a)是名词性短语，可以作为句子的宾语。of 后面的成份作为宾语的修饰成份。 . 定语成份 句子定语成份一般是指做句子主语和宾语成份的修饰词，一般为形容词和形容词短语，也有分词形式的定语，一般把它归为分词结构这一考点中。 例5.jupiter,the closest of the giantplanets to earth,has_____solid surface and is surrounded by zones of intense radiation. (a) not (b) nor (c) no (d) neither (10/96 7) key：c 分析：空格处缺少宾语solid surface 的修饰语，仅c符合条件。 6. 表语成份 常考内容包括名词，形容词和介宾短语。 例6.the pulitzer prize has been_____in american literature for more than seventy years. (a) the award most prestigious that (b) the most prestigious award (c) a prestigious award that most (d) most prestigious award (01/97 15) key：b 分析：全句缺少表语。award是表语中心词，前面是形容词最高级修饰。 7. 状语成份 常考的状语成份为：介宾短语做状语，形容词短语做状语，分词短语做状语，不定式做状语等。 例7.direct information on the chemical composition of the moon because available in 1969_____of the first apollo mission to land on the moon. (a) with the return (b) returning (c) when returned (d) and the return (01/98 5) key：a 分析：空格前主句结构完整，应填入辅助成份，(b)(c)均无法与后面的成份衔接，(d)and连接的成份无法与前面平行，又不是一个单句成份，(a)是介词短语做状语。 名词性从句 名词性从句是指定完整的句子中以名词形式出现的从句成份，主要包括主语从句，宾语从句，表语从句，补语从句。 8. 主语从句 例8._____touching in o henryu2019s stories is the gallantry with which ordinary people struggle to maintain their dignity. (a) most is (b) it mostly is (c) is it most (d) what is most (05/98 5) key：d 分析：(a)(b)(c)都会造成主句谓语动词重复，（d）what引导的名词性从句做主语。 9.宾语从句 从句是主语的宾语。格式：sub+vt+从句引导词+句子 例9.astronomers estimate ______called the pleiades in the constellation taurus is 415 light-years away from earth. (a) that a loose cluster of stars (b) a loose cluster of stars is (c) that is a loose cluster of stars (d) there is a loose cluster of stars (08/01 11) key：a 分析： estimate是及物动词，后面的空格应该是宾语，或者宾语从句。(a)从句的谓语是后面的is。（b）（c）（d）其谓语和后面的谓语矛盾了，一个句子只能有一个谓语 10.表语从句 11.同位语 同位语是toefl语法每次必考的内容之一，一般做主语或是宾语的同位语，句子的主干已经完整，同位语作为一个插入成份作补充说明之用。 同位语成份根据位置不同可分为前位同位语和后位同位语，即同位语分别在主语的前面或后面，另外还有that引导的同位语从句。 例11。the liberty bell, formerly housed in independence hall, --- in philadelphia, was moved to a separate glass pavilion in 1976. (a) which a historic building (b) a historic building which (c) was a historic building (d) a historic building （05/01 12） key：d 分析：句子有完整的主谓宾，空格部分成分是主语的同位语 (a) (b)从句少谓语；(c) 后边已经有谓语了，此处又没有从句引导词，was多余。 12.关系词用法 关系词分关系代词和关系副词，关系代词有who/whose/whom,which,that,what,关系副词有where,when,why,how等，主要引导定语从句，宾语从句，主语从句表语从句等。 例12。generally, the representatives ------ a legislature are constitutionally elected by a broad spectrum of the population. (a) who they compose (b) who compose (c) ad compose (d) compose (01/01 3) key：b 分析：这是一个主从句。主语representatives 后已经有了谓语其后的空格应该是个从句。 （a） 从句有个多余的主语they ；(c)解释不通；(d) 无从句引导词，形成2个谓语。 13.连词用法 两个句子之间，一般要有连接词。常见的连词有： 对等连词，连接两个并列的句子：and,or,but,whereas,so,for,等等。 连接主语和从句的连词： if,when,while,where,unless,since,until,as,because,although,as soon as,even,if,even though,as if,等等。 例13。in the arctic tundra, ice fog may form under clear skies in winter, ____ coastal fogs or low stratus clouds are common in summer. (a) because of (b) whereas (c) despite (d) that (08/00 6) key：b 分析：空格前后为两个完整的分句,则空格处应填一个连词,连接前后两个句子.despite为介词，because of 不跟句子。 14.省略结构 在状语从句中，“主语+be动词”常常有省略现象，这是允许的，但必须保证两个成份同时存在或同时省略。 15.比较结构 比较结构常考内容为：比较级的表达，比较的对等成份，最高级的冠词的应用。比较级后半部分可倒装或不倒装。 16.倒装结构 倒装是toefl必考语法点之一，一般而言，在以下几种情况下，要用倒装结构。 ? 否定副词提前，? 主句倒装。如hardly,rarely,not only,not until等。 ? only + 介词短语/副粗短语做状语提前，? 后主句倒装。 ? so + 形容词/副词提前，? 后倒装。 ? 表语提前，? 用倒装结构。 例16。 among the first plants to grow on the land regions of the earth _____, which in prehistoric times grew to immense size (a) were horsetail rushes (b) horsetail rushes (c) horsetail rushes were (d) and horsetail rushes （01/99 1） key：a 分析：amongu2026u2026引导的介词短语放在句首，且没有用逗号隔开，后面的谓语部分应该倒 装，只有a符合条件。（b）缺全句谓语 ；（c）如果earth后面有逗号，且were后面还有表语成分则可；（d）and 引起并列连接，可是本句中无法有符合逻辑的并列成分。 17.特定句型 toefl每次考试的语法中，都有一些特定句型的考题。主要可归纳为以下几类： ? 强调句型。 ? 虚字句型。 ? 应变句型。 18.固定搭配 在英语表达中，有些词或词组有着其特有的用法，在这里作为考点单列出来，作为固定搭配，希望引起大家注意。 make possible sth/that. 例18。 during the decades after the united states civil war, a host of technical advances made possible ______and uniformity of railroad service. (a) a new integration (b) for a new integration (c) that a new integration (d) and a new integration (08/01 14) key：a 分析： （b）made 后面没有了宾语；（c）that后面没有谓语，无法构成从句；（d）made后面没有了宾语，而且and 前后也不是平行结构。 2. 改错部分 这一部分除了涉及选择填空部分的基于句子结构分析的句法考点外，更多的是侧重对词的考查，要求考生的词的词性，成份，语态，搭配等都有清楚的认识。因为词的变化和搭配多种多样，很难全部掌握，因此本部分往往是影响语法最后高分获得的关键所在。19.冠词用法 冠词用法在每次toefl考试中都会出现，主要考查：a/an的混用，a/an的遗漏，定冠词 调和the的多余或遗漏。 例19。since the advent of rock music in the 1950"s the popular music of the a b united states has become a significant musical influence around world. c d key：d around the world (10/99 29) 分析：world应加冠词the表特指。 20.动名词用法 动名词是由动词变化而来，和名词一样可以做主语，宾语，表语，同时也具有动词的功能，后可以加宾语或副词修饰，这又是它区别于一般名词的特性。 一般来说，动名词也有逻辑主语，如果与主语不一致时，必须加上所有格形式。若要表示被动或完成时态，前用being + 分词或having + 分词。 21.动词不定式 动词不定式在 toefl考试中主要考察3知识点：不定式后动词要用原形，不定式记号“to”的省略，不定式的特殊语意。 例21。there were once only eight major lakes or reservoirs in texas, but today a b there are over 180, many built to storing water against periodic droughts. c d key：d to store (08/01 21) 分析：此处的to 是不定式，后面应该接动词原形。 22.分词结构 分词包括现在分词和过去分词，主要表示主动和被动的区别。一般分词结构在句中的成份为状语，可以表示原因，时间，条件，伴随等，也可作为定语修饰名词，要注意分词和逻辑主 语的搭配。 例22。the first fiction writer in the united states to achieve international fame a b c was washington irving, who wrote many stories, included " rip van winkle" and d "the legend of sleepy hollow". (01/00 23) key：d including 分析：d前面已经是一个完整的句子，d改为including做伴随状语,说明前面的主句。 23.平行结构 一些固定的搭配和连词连接相同的成分，根据这个结构就可判断相应的错误所在。这些词包括and,or,but,,bothu2026andu2026,as well as,rather than,other than,notu2026 butu2026,eitheru2026oru2026,nitheru2026noru2026,the sameu2026asu2026,suchu2026asu2026,not onlyu2026but alsou2026等，平行结构是遵循对等原则，包括词性平行，名词单复数平行，时态平行。 例23。three fundamental aspects of forest conversation are the protection of a immature trees, the use of proper harvesting methods, and provide for an b c environment that supports reproduction. （01/00 24） d key：c provision 分析：考点是平行结构,and表示并列,所以c应当用名词. 24.动词的语态 动词的语胎主要是指主动与被动的区分。 例24。the one-fluid theory of electricity was proposing by benjamin franklin, a b a man famous for his wide interests and great attainments. （08/01 37） c d key：b proposed 分析：由by sb.可知，这是个被动语态。b错。 25.动词的时态 时态包括过去式，过去完成式，现在式，现在完成式，将来式等，要根据时间状语和句子的意思来区分。26.主谓一致 主谓一致指谓语动词的形式和主语搭配要一致。 27.代词用法 主要考查内容为：所有格，反身代词的误用，代词指代时人称和数上的不一致。 例27。polar bears are bowlegged and pigeon-toed, adaptations that enable this a b massive animals to maintain their balance as they walk. （01/00 20） c d key：b these 分析：人称代词单复数的误用。句中谓语动词are提示a bears正确,则b this应该用其复数形式。28.介词用法 介词用法主要考查介词的多余，遗漏和介词的误用等。 29.名词单复数 常考知识点为复数名词的变形，集合名词，不可数名词的用法，单复数同形的情况，名词做形容词时的形式。 一般来是单数可数名词前有冠词修饰，若无冠词则要用复数形式，或前有a/an修饰的名词应是单数形式，前有many.a great number of,a few或数词等修饰词时，名词一般用复数，而有a great deal,a great amount of,much,a little等修饰时，后一般为不可数名词。当名词做形容词修饰其他名词时，一般用单数形式，特殊如：sales tax,sports program,systems engineering等。 例29。the ability to talk is one of the skill that make humans different from a b c the rest of the animal world. (01/00 18) d key：b kills 分析：one of 后面要加名词复数。 30.词序 常考知识点为：修饰词与被修饰词位置颠倒，系表位置颠倒等。 例30。caves are formed by the chemical or action mechanical of water on soluble a b rock, by volcanic activity, and by earthquakes. （01/00 21） c d key：a mechanical action 分析：除了定语后置(n.+adj.),其它都是adj+n。 31.词的误用 这是toefl考试中考查最频繁的一类题型，包括： ? 词性的错用。（如平行结构中） ? 限定词的错用。 ? 表“人”和表“物”的词的错用。 例31。having gained a reputation as a daring, intrepid journalist, nellie bly a became the first female report assigned to the eastern front during the first b c d world war. (10/99 19) key：c reporter 分析：此处为“记者”

《高中英语语法-主谓一致》由留学liuxue86.com我整理。本内容整理时间为05月12日，如有任何问题请联系我们。 主谓一致 语法复习二、主谓一致 在英语句子里,谓语受主语支配,其动词必须和主语在人称和数上保持一致,这就叫主谓一致。寻其规律,大致可归纳为三个原则,即语法一致、逻辑意义一致和就近一致原则。 (一)语法一致原则:语法上一致就是谓语动词和主语在单、复数形式上保持一致。 1、以单数名词或代词、动词不定式短语、动名词短语或从句作主语时,谓语动词一般用单数形式;主语为复数时,谓语动词用复数形式。如:His father is working on the farm. / To study English well is not easy. / What he said is very important for us all. / The children were in the classroom two hours ago. / Reading in the sun is bad for your eyes. 注意:由what引导的主语从句,后面的谓语动词多数情况用单数形式,但若表语是复数或what从句是一个带有复数意义的并列结构时,主句的谓语动词用复数形式。如:What I bought were three English books. / What I say and do is (are) helpful to you. 2、由连接词and或both u2026 and连接起来的合成主语后面,要用复数形式的谓语动词。如:Lucy and Lily are twins. / She and I are classmates. / The boy and the girl were surprised when they heard the news. / Both she and he are Young Pioneers. 注意:① 若and所连接的两个词是指同一个人或物时,它后面的谓语动词就应用单数形式。如:The writer and artist has come.; / ② 由and连接的并列单数主语前如果分别有no, each, every more than a (an) , many a (an)修饰时,其谓语动词要用单数形式。如:Every student and every teacher was in the room.. / No boy and no girl likes it. 3、主语为单数名词或代词,尽管后面跟有with, together with, except, but, like, as well as, rather than, more than, no less than, besides, including等引起的短语,谓语动词仍用单数形式;若主语为复数,谓语用复数形式。如:Mr Green, together with his wife and children, has come to China. / Nobody but Jim and Mike was on the playground. / She, like you and Tom, is very tall. 4、either, neither, each, every 或no +单数名词和由some, any, no, every构成的复合不定代词,都作单数看待。如:Each of us has a new book. / Everything around us is matter. 注意:① 在口语中当either或neither后跟有"of+复数名词(或代词)"作主语时,其谓语动词也可用复数。如:Neither of the texts is (are) interesting. ② 若none of后面的名词是不可数名词,它的谓语动词就要用单数;若它后面的名词是复数,它的谓语动词用单数或复数都可以。如:None of us has (have) been to America. 5、在定语从句时,关系代词that, who, which等作主语时,其谓语动词的数应与句中先行词的数一致。如:He is one of my friends who are working hard. / He is the only one of my friends who is working hard. 6、如果集体名词指的是整个集体,它的谓语动词用单数;如果它指集体的成员,其谓语动词就用复数形式。这些词有family, class, crowd, committee, population, audience等。如:Class Four is on the third floor. / Class Four are unable to agree upon a monitor. 注意:people, police, cattle等名词一般都用作复数。如:The police are looking for the lost child. 7、由"a lot of, lots of, plenty of, the rest of, the majority of + 名词"构成的短语以及由"分数或百分数+名词"构成的短语作主语,其谓语动词的数要根据短语中后面名词的数而定。如:There are a lot of people in the classroom. / The rest of the lecture is wonderful. / 50% of the students in our class are girls. 注意: a number of"许多",作定语修饰复数名词,谓语用复数;the number of"u2026的数量",主语是number,谓语用单数。 8、在倒装句中,谓语动词的数应与其后的主语一致。如:There comes the bus./ On the wall are many pictures. / Such is the result. / Such are the facts. (二)逻辑意义一致原则:逻辑意义一致就是谓语动词的数必须和主语的意义一致(因有时主语形式为单数,但意义为复数;有时形式为复数,但意义为单数)。 1、what, who, which, any, more, all等代词可以是单数,也可是复数,主要靠意思来决定。如:Which is your bag? / Which are your bags? / All is going well. / All have gone to Beijing. 2、表示"时间、重量、长度、价值"等的名词的复数作主语时,谓语动词通常用单数形式, 这是由于作主语的名词在概念上是一个整体,如:Thirty minutes is enough for the work. 3、若英语是书名、片名、格言、剧名、报名、国名等的复数形式,其谓语动词通常用单数形式。如: "The Arabian Nights"is an interesting story-book. 4、表数量的短语"one and a half"后接复数名词作主语时,其谓语动词可用单数形式(也可用复数。如:One and a half apples is (are) left on the table. 5、算式中表示数目(字)的主语通常作单数看待,其谓语动词采用单数形式。如:Twelve plus eight is twenty. / Fifty-six divided by eight is seven. 6、一些学科名词是以 -ics 结尾,如:mathematics, politics, physics 以及news, works等,都属于形式上是复数的名词,实际意义为单数名词,它们作主语时,其谓语动词要用单数形式。如:The paper works was built in 1990. / I think physics isn"t easy to study. 7、trousers, glasses, clothes, shoes, 等词作主语时,谓语用复数,但如果这些名词前有a (the) pair of等量词修饰时,谓语动词用单数。如:My glasses are broken. / The pair of shoes under the bed is his. 8、"定冠词the + 形容词或分词",表示某一类人时,动词用复数。 (三)就近一致原则:在英语句子中,有时谓语动词的人称和数与最近的主语保持一致。 1、当两个主语由either u2026 or, neither u2026 nor, whether u2026 or u2026, not only u2026 but also连接时,谓语动词和邻近的主语一致。如:Either the teacher or the students are our friends. / Neither they nor he is wholly right. / Is neither he nor they wholly right? 2、there be句型be动词单复数取决于其后的主语。如果其后是由and连接的两个主语,则应与靠近的那个主语保持一致。如:There are two chairs and a desk in the room.. 注意:Here引导的句子用法同上。 练习:主谓一致 1.I, who____ your friend, will try my best to help you with your English.

一、详细释义： , n. , 治疗，治愈，疗法 , 例句： ,Prevention is always more sensible and less costly than cure.,预防总是比治疗更明智，而且花费更少。, 例句： ,Doctors are searching for a cure that will wipe out cancer.,医生们正在寻找消灭癌症的医疗方法。, （被）硫化；（被）加工处理 [I,T] , 例句： ,The tobacco leaves are cured in wood- *** oke.,菸叶是用木材的烟所加工储存的。, v. , 治疗，治愈；矫正 [I,T] , 例句： ,When I left the hospital I was pletely cured.,出院时，我已经完全痊愈了。, 例句： ,He tried to cure his child of the habit.,他试着去矫正他孩子的那种习惯。, 二、词义辨析： , cure,treat,heal,remedy ,这些动词都有“治疗、医治”之意。cure主要指治愈疾病。treat普通用词，指接受并诊治病人。heal侧重指治愈伤口、伤痛如灼伤等。remedy着重用药物对病人进行治疗。, 三、词义辨析： , drug,medicine,medication,remedy,cure,chemical ,这些名词都有“药”之意。drug普通用词，含义广泛，可指任何用于预防或治疗肉体上或精神上疾病的药品。用复数形式，多指毒品。medicine普通用词，可指药物的总称，也指一切有利于健康的东西。medication指医生开给病人用的一切药物，从最简单的阿斯匹林到最复杂的药物。remedy普通用词，侧重指对恢复健康有效的药品或治疗方法。cure比remedy更强调使身体恢复健康的疗法或良药。chemical多指工业或化学中的药品，有时也指医药中的药品。, 四、相关短语： ,faith cure,n. 信仰疗法, 一、参考例句： ,Prevention is better than cure.,防胜于疗。,Drastic measures were taken to cure inflation.,为了处理通货膨胀， *** 采取了严厉措施。,Aspirin is a wonderful cure for colds.,阿斯匹林是治感冒的妙药。,This shampoo will cure your dandruff.,这种洗发水可除掉头皮屑。,There is still no cure for AIDS.,The only cure for grief is action.,行动是治疗心灵创伤的唯一灵丹妙药。,If it can cure nothing else, it at least can cure man of megalomania.,它如果不能治愈别的疾病，至少能够治愈人类的狂妄自大的。,Scientists are in search of a cure for the disease.,科学家们正在寻找治疗这种疾病的方法。,Prevention is always more sensible and less costly than cure.,预防总是比治疗更明智，而且花费更少。,Scientists are trying hard to find a cure for cancer.,科学家们正努力寻找治疗癌症的方法。

chemical trends化学趋势trends[英][trendz][美][trendz]n.趋势( trend的名词复数 ); （海岸、河流、道路等的）走向; 流行; 时尚; v.伸向( trend的第三人称单数 ); 趋向; 倾向; 使趋向; 例句:1.This unusual marriage of interests reflects two trends. 这种不寻常的利益联姻反映了两种趋势。

chemical screens释义化学屏幕screens英-[skri:nz]美-[skri:nz]释义n. 屏幕（screen的复数）；卡位v. 遮蔽；拍电影（screen的第三人称单数形式）

第一种说法是错的。millions of数百万的；数以百万计的用法说明： 类似 millions of 的还有： dozens of; scores of; hundreds of; thousands of.....这些短语有几个共同点：1. 都是表示一个大概，模糊的数量。2. 都是只能修饰可数名词的复数形式。例句筛选：1.Chemical plants throughout the United States produce millions of pounds of melamine a year.美国的化工厂每年生产数以百万磅的三聚氰胺。2.fter millions of years in this position the new moon was drawn into a collision at a speed of less than three kilometres per second.几百万年后，此状况下的新月亮以低于每秒3公里的速度要对撞了。

insole的意思是鞋垫。insole主要用作为名词，第三人称复数形式为insoles。意思有鞋垫，中底，内底，鞋内底。同义词有innersole。双语例句1、Additionally，the part on the surface of the insole body for foot arch is provided with a projection corresponding with the foot arch。此外，在脚心所处的鞋垫主体表面的部位设有与脚心相对应的隆起部件。2、The insole（EVA sock liner）that the PT-03 comes with is a standard foam insert that provides a bit of cushion but no support。附带的鞋垫（EVA鞋垫）是标准的泡沫鞋垫，提供了一点减震性，但没有提供支撑性。3、The machine is applicable to the insole molding of men and women"s shoes and for easy lasting。本机适用男女鞋中底定型使其贴楦以利结帮。4、These resins are widely used for nonwoven insole，chemical tablets，LiXin cloth and related industries。上述树脂在无纺布中底板、化学片、丽新布及相关行业得到广泛应用。

d 有逗号。所以which。是句号就是them。

1/ some other people 可以用,或者说 some others也行 看下面我给你的解释 other后既可接可数名词复数形式又可接不可数名词,如：可数,other pencils 其它的铅笔,other students 其他的学生.不可数other tea 别的/其它的茶,other information 别的/其它消息. the other 定指其它的……,其后可接可数名词和单数,如： the other book 另外的一本书, the other map 另一张地图, 其后也可跟可数名词的复数形式,如： the other flowers 其他的花朵,the other teachers 其它的老师们,还可以接不可数名词,如：the other water 剩下的水,the other beer 别的啤酒 2/ others 其用法相当于复数名词,此词不能用作定语,表示的意思是“不具体的某些东西”,如： This chemical is poisonous .Others are poisonous ,too .( others = other chemicals ) 但是如果others前用了the ,则表示具体的别的东西.如： I don"t want these books .Please give me the others .( the others = the other books others 和some对比使用时,是“有些”的意思而不是做“其他”讲,如:Some cleaned the windows,others mopped the floor.有的擦窗户,有的擦地板. the others 是“其余的”意思,表示在一个范围内的其他全部,如:This dictionary is better than the others.这本字典比别[其余]的好. the other 是其中的“另一个”,如:Give me the other one; not this one.给我那一个,不是这一个. 两个中的“另一个”是“the other”; 不定数目中的“另一个”是“another” ,如:This glass is broken.Get me another.这个杯子坏了,给我另拿一个来.(在许多杯子中的一个) 3/ B因为 dances动词三单形式,而动词后面必须跟副词修饰而不是形容词,所以用well,good 是形容词,修饰名词或代词等等.后半句为“好的一天”很明显,后半句横线处应为形容词的词性

millions of 数百万的 eg. millions of people 数百万人million of 是错的

Other 表示“另一个或另一些”是泛指，当形容词或代词用 Others 表示“另一些”，是泛指。是代词，后面不能再加名词 The others 是特指 The other与other同义，是特指 Another 表示“另一个”，是泛指。如： I have two pens. One is red and the other is green.. Some people like singing, others like dancing. I don”t like this one. Please give me another one. the other 是特指的另外一个 other 是除自己外的“别人” others是其他人，一般是3个或以上 another是两个人中，除自己外的另外一个人 other 表示“其他的”或者“另一些” 是形容词 后面加名词 如果是可数多用复数 some children like apples, other children like bananas. the other 表示范围内的另一个（范围内一共两个） we have two hands. one is on the left, the other is on the right. the others表示范围内的另一些（范围总数通常多于两个个）后面不能加名词 There are 40 students in our class, three are American, the others are Chinese. another 另外的一个（有任意性）后面加可数名词单数,也可以不加名词直接使用。 I have eaten an apple, but I still want another(apple). other后既可接可数名词复数形式又可接不可数名词，如：可数，other pencils 其它的铅笔，other students 其他的学生。不可数other tea 别的/其它的茶，other information 别的/其它消息。 the other 定指其它的u201eu201e，其后可接可数名词和单数，如： the other book 另外的一本书， the other map 另一张地图， 其后也可跟可数名词的复数形式，如： the other flowers 其他的花朵，the other teachers 其它的老师们，还可以接不可数名词，如：the other water 剩下的水，the other beer 别的啤酒 others 其用法相当于复数名词，此词不能用作定语，表示的意思是“不具体的某些东西”，如： This chemical is poisonous . Others are poisonous , too . ( others = other chemicals ) 但是如果others前用了the ，则表示具体的别的东西。如： I don"t want these books . Please give me the others .( the others = the other books another，作形容词时，是指在原有的基础上再加一（些），表示“再一（些）”或“另外一个（些）”的意思。 another还可作代词，意思与作形容词时一样。another作形容词时，是指在原有的基础上再加一（些），表示“再一（些）”或“另外一个（些）”的意思，在心理上至少有三个。 another还可作代词，意思与作形容词时一样。 the other也是既能作形容词，又能作代词。但它一般用来表示总数为二时的“另外一个”，经常与one搭配。 other也能既作形容词又可作代词，意思是“别的，另外的”。 others只能作代词，意思是“其它的人（物或事等）”，常用来泛指。 the others也只能作代词，意思与others相近，但常用来特指。 another与other的区别。 ①Some students like English and other students (others) like physics. 有些学生喜欢英语，有些学生喜欢物理。 【解析】other表示“别的”，“另外的”，只能与复数名词连用。但other前有冠词the即可与单数名词连用。如： I have two pens. One is blue. The other (pen) is black. 我有两枝钢笔。一支是蓝色的，另一支是黑色的。 ②John did better than all the other players in the sport. 在那项运动中John比所有别的运动员都出色。 【解析】the other加复数名词指的是一定范围内“所有其余的人或事物”，是特指；而other加复数名词却是没有明确范围的“另外的人或事物”。如： We must think more of other comrades. 我们必须多想想别的同志。 ③ This shirt is too large for me. Please show me another. 这件衬衫我穿太大。请另外拿一件我看看。（一般商店不会只有两件衬衫） 【解析】another, the other作代词的用法。The other表示“两个数量中的另一个”，表示特指，总数为俩；another表示“总数为三个以上中任意的另一个”，表示泛指。如： His parents both work in a hospital. One is a doctor and the other is a nurse. 他父母都在一家医院工作。一个是医生，一个是护士。（父母为两个人） 其他习惯用法one another, from oneu201eto another, the other day = a few days ago，every other day/ week/year， someu201e, othersu201e，如： I met Mr. Smith in the park the other day. 前几天我在公园里碰见了Smith先生。 While at the university, he went to the library every other day. 在大学时他每隔一天去图书馆一次。 Some people like football, others like volleyball. 有些人喜欢足球，有些人喜欢排球。 They are very different from one another. 他们互相之间差别很大。 When Americans moved from one place to another, they took their dialects with them. 当美国人从一个地方迁移到另一个地方时， other指另外的人或物；other泛指别人，可与some连用；the other 指两个中的另一个，常和one连用；the others表示其余所有的人或物；another则泛指另一个。 回答者：萧萧羽禺 - 魔法学徒 一级 4-15 15:41 other 可以做形容词，表示其他的，比如other people其他的人。 也可以做代词，但是做代词时一般不以原形出现，一般用以"the other"或者以复数形式“others”出现。 others 和some对比使用时, 是“有些”的意思而不是做“其他”讲, 如:Some cleaned the windows, others mopped the floor. 有的擦窗户, 有的擦地板。 the others 是“其余的”意思, 表示在一个范围内的其他全部, 如: This dictionary is better than the others. 这本字典比别[其余]的好。 the other 是其中的“另一个”, 如:Give me the other one; not this one. 给我那一个, 不是这一个。 两个中的“另一个”是“the other”; 不定数目中的“另一个”是“another” , 如:This glass is broken. Get me another. 这个杯子坏了, 给我另拿一个来。(在许多杯子中的一个) any other 刚指其他一切的什么、、、 another 指另一个，没有固定的范围。比如：this dress is dirty,please change another one for me.这件裙子脏了，再给我换一件吧。 another的意思是另一个（许多），比如你去买手表，售货员给你推荐一个，但是你不喜欢，这时你就可以说：“请给我另一个。”（Please give me another one）。这时就用another other的意思是其他的，后面接名词 others的意思是别人，someu201eu201eothersu201eu201e的意思是一些u201eu201e另一些u201eu201e the other的意思是另一个（两个），oneu201eu201ethe otheru201eu201e的意思是一个u201eu201e另一个，比如说一对双胞胎就可以说一个u201eu201e另一个u201eu201e，这时的另一个就用the other the others是“其余的”意思, 表示在一个范围内的其他全部, 如： This dictionary is better than the others. 这本字典比别其余的好。 例句解析 ①Some students like English and other students (others) like physics. 有些学生喜欢英语，有些学生喜欢物理。 【解析】other表示“别的”，“另外的”，只能与复数名词连用。但other前有冠词the即可与单数名词连用。如： I have two pens. One is blue. The other (pen) is black. 我有两枝钢笔。一支是蓝色的，另一支是黑色的。 ②John did better than all the other players in the sport. 在那项运动中John比所有别的运动员都出色。 【解析】the other加复数名词指的是一定范围内“所有其余的人或事物”，是特指；而other加复数名词却是没有明确范围的“另外的人或事物”。如： We must think more of other comrades. 我们必须多想想别的同志。 ③ This shirt is too large for me.

mice的意思是老鼠。用法：1. 确保使用复数形式：由于mice是mouse的复数形式，所以只能在需要表达多只老鼠的情况下使用mice。如果只是单独指代一只老鼠，需要使用mouse。2. 表达数量和状态：在表达多只老鼠的状态或情况时，mice可以表示数量或状态。例如，"There are five mice in the room"指的是房间里有五只老鼠，而"There is a problem with mice in the house"则指房子里有老鼠问题。3. 注意固定词组的用法：在一些固定的词组中，mice被用来表示多只老鼠。例如，"catch mice"表示捕捉老鼠，"field mice"指野鼠。4. 注意大小写：在书写时，mice需要大写。小写的mice通常是指Multiple Integrated Laser Engagement System（多功能激光验战系统）的缩写。总之，mice是一个表示“老鼠”的复数形式。在表达数量或状态是指代多只老鼠时，需要使用mice。mice双语例句：1. There are mice running around in the barn. (谷仓里有老鼠乱窜。)2. The experiment involved exposing mice to a certain chemical. (实验涉及将老鼠暴露在某种化学物质下。)3. We set up traps to catch the mice that were plaguing the house. (我们设置了陷阱，以捕捉骚扰房屋的老鼠。)4. The study found that the behavior of the mice changed depending on the type of food they were given. (研究发现，老鼠的行为取决于他们所食用的食物的种类。)5. The farmer"s cat is a skilled mouse catcher. (那个农夫的猫是一只技艺高超的老鼠捕手。)6. The lab uses mice for medical research. (该实验室利用老鼠进行医学研究。)
