much和many的用法

Many和Much用法 ①many和much都作“许多”解，但many用于修饰可数名词，而much修饰不可数名词。例如： 1. China has many oil fields. 中国有许多油田。 2. In our view, there is much oil here. 在我们看来，这里有许多石油。 ②代词many和名词much用法举例： 1. Many of the students want to sum up the past experience before going on. 许多学生（原意为：学生中间有许多人）要总结一下过去经验在继续干。 2. Much of the waste acid is utilized. 废酸中大部分被利用了。 Many of the workers were at the meeting. Much of the time was spent on learning. ③“much（副词）+比较级”作“……得多”解： 1. The sun is much large than the moon. 太阳比月亮大得多了。 2. This problem seems much more difficult than that one. 这道题似乎比那道题难得多。 ④副词much修饰动词、过去分词时作“十分”解： 1. We all love Beijing very much. 我们大家都非常热爱北京。 注：上述两种句子，一般不能用very代替much。 ⑤ many和much的一些常用词组： many a time 许多次 how many books 多少书 how much water 多少水 as much (many) as 像……那么多 much加不可数名词，如much milk many加可数名词复数，如many apples How many加可数名词复数，如How many pears How much加不可数名词，如How much water How much也可用于问价钱，如How much are the apples？意思是这些苹果多少钱？这是How many与How much的最大区别 Some和any 既可以修饰可数名词又可以修饰不可数名词，some常用在肯定句中，而any则常用在否定和疑问句中。因此 some和any 的用法主要是考虑用在肯定句、疑问句还是否定句中，与名词的可数与否无关。 some意为“一些”，可作形容词和代词。它常修饰可数名词复数。如：some books一些书，some boys一些男孩，也可修饰不可数名词，如：some water一些水，some tea一些茶叶，some常用在肯定句中。any 意为“任何一些”，它也可修饰可数名词复数或不可数名词，常用于疑问句和否定句。如： s --I have some tea here. 我这儿有些茶叶。 --Do you have any friends at school? 你在学校有些朋友吗? --I have some English books我有英语书 但在表示建议，反问，请求的疑问句中，或期望得到肯定回答时，多用some而不用any。如： Would you like some coffee? 你要不要来点咖啡?

How many和 how much的用法

How many和how much的用法 所谓的名词，即是指物品、动、植物，以及地方的名称。但有些东西是可以数得出来的，而有些则是数不出来的。数得出来的东西，便称为可数名词，数不出来的东西，即称为不可数名词。平时所见的可数名词有椅子、桌子、人、树木等；而根本数不出来的不可数名词有水、空气、感情等，但有些则是太小，或平时也没有细数者，如头发、沙子、稻米等，亦归为不可数名词。依此推想，你可以想到有哪些可数名词？哪些不可数名词呢？试各举五个例子： 但在英语中，有些名词的归类却不是我们平时的可数、不可数概念，如fish（鱼）、fruit（水果）等，这点需要特别的注意。 做笔记的方式：平时在学得一个新名词时，随时不忘随手在名词后标上注记，可数名词记为[C]，不可数名词记为[U]。 many 和much 的差别： 这两个字虽然都是，很多的意思，但many 后面是接可数名词，而much 后面是接不可数名词，例：1．Do you have many books?（books 为可数名词复数，故前用many。） 2．Do you have much homework?（homework 为不可数名词，故前用much。） How many ...? 的用法： 我们平时说话时，总会说或听到这样的句子： 1．你有几本书？（或你有多少本书？） 2．他有几张卡片？（或他有多少张卡片？） 3．Mary 今天有几堂课？（或Mary 今天有多少堂课？） 上述三个例句最大的特色是，都有几???或多少???的问数量之词，都把它们译成英文看看，是不是也都有相似的字出现？ 4．How many books do you have? 5．How many cards does he have? 6．How many classess does Mary have today? 若以一个表格的方式，将上述的句子做分类，你应该可以归纳出这样一个表： How many＋可数复数名词＋do/does＋主词＋have？ 其实How many …? 的使用还不只于此，上述句型中的动词，并不只限于have，先看看底下的例子：7．How many candies do you eat every morning? 你每天早上吃多少糖果？） 8．How many letters does she write every day? 她每天写多少信？） 想想看：试试将底下的句子翻译成英文。 1．你每天看多少本书？ 2．Tom每天晚上吃多少热狗？ 3．他有多少朋友呢？ 4．这群学生每天打几场篮球赛？ 5．Amanda 每天读几科？ How much ...? 的用法： 上述的句型，因为是用many 的关系，只限用于问多少可数名词时，若是要问不可数名词的数量时，则将many 为much 即可，例： 9．How much money do you get? （你拿到多少钱？）

when,while,as的区别

一、根据从句动作的持续性来区分 1.“主短从长”型：即主句是一个短暂性的动作，而从句是一个持续性动作，此时三者都可用。如： Jim hurt his arm while [when, as] he was playing tennis. 吉姆打网球时把手臂扭了。 As [When, While] she was waiting for the train, she became very impatient. 她在等火车时，变得很不耐烦。 注意：as用于引出一个持续性动词表示“在……期间”时，其谓语通常只能是那些含有动作和发展意味的动词，一般不能是那些不用于进行时态的动词(如be, seem, love, want, agree, see, know, have 等)，所以下面一句中的while不能换为as： A：I’m going to the post office. 我要去邮局。 B：While you are there, can you get me some stamps? 当你在邮局时，能帮我买几张邮票吗? 若主句与从句表示的是两个几乎同时发生的动作，含有类似汉语“刚要……就”“正要……却”的意思，英语一般要用as(也可用when)，且此时通常连用副词just。且此时，从句一般用进行时，主句用短暂性动词的一般时态。【注意与六区别】 I caught him just when [as] he was leaving the building. 他正要离开大楼的时候，我把他截住了。 Just as [when] the two men were leaving, a message arrived. 就在这两个人要离开的时候，突然有了消息。 2.“主长从长”型：即主句和从句为两个同时进行的动作或存在的状态，且强调主句动作或状态延续到从句所指的整个时间，此时通常要用while。如： I always listen to the radio while I’m driving. 我总是一边开车一边听收音机。 He didn’t ask me in; he kept me standing at the door while he read the me ssage. 他没有让我进去，他只顾看那张条子，让我站在门口等着。 但是，若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时，则习惯上要用as。如： He swung his arms as he walked. 他走路时摆动着手臂。 I couldn’t remember a story to tell the children, so I made one up as I went along. 我想不出有什么故事可给孩子讲了，只好现编现讲。 3.“主长从短”型：即主句是一个持续性动作，而从句是一个短暂性动作，此时可以用a s或when，但不能用while。如：

while、when和as的用法区别

as when while 的区别和用法 as when while的用法 一、as的意思是“正当……时候”,它既可表示一个具体的时间点，也可以表示一段时间。as可表示主句和从句的动作同时发生或同时持续，即“点点重合”“线线重合”；又可表示一个动作发生在另一个动作的持续过程中，即“点线重合”， 但不能表示两个动作一前一后发生。如果主句和从句的谓语动词都表示持续性的动作，二者均可用进行时，也可以一个用进行时，一个用一般时或者都用一般时。 1、As I got on the bus，he got off. 我上车，他下车。（点点重合）两个动作都是非延续性的 2、He was writing as I was reading. 我看书时，他在写字。（线线重合）两个动作都是延续性的 3、The students were talking as the teacher came in. 老师进来时，学生们正在讲话。（点线重合）前一个动作是延续性的，而后一个动作时非延续性的 二、while的意思是“在……同时（at the same time that )”“在……期间(for as long as, during the time that）”。从while的本身词义来看，它只能表示一段时间，不能表示具体的时间点。在时间上可以是“线线重合”或“点线重合”，但不能表示“点点重合”。例如： 1、He was watching TV while she was cooking. 她做饭时，他在看电视。（线线重合） 2、He was waiting for me while I was working. 我工作的时候，他正等着我。（线线重合） 3、He asked me a question while I was speaking. 我在讲话时，他问了我一个问题。（点线重合）

第七--when-while-as-区别及练习.

When while as区别 一、根据从句动作的持续性来区分 1、“主短从长”型：即主句是一个短暂性动作，而从句是一个持续性动作，此时三者都可用。如： Jim hurt his arm while［when， as］ he was playing tennis. 吉姆打网球时把手臂扭伤了。 2、“主长从长”型：即主句和从句为两个同时进行的动作或存在的状态，且强调主句动作或状态延续到从句所指的整个时间，此时通常要用while。 I always listen to the radio while I’m driving. 我总是一边开车一边听收音机。 He didn’t ask me in; he kept me standing at the door while he read the message. 他没有让我进去，他只顾看那张条子，让我站在门口等着。 但是，若主句和从句所表示的两个同时进行的动作含有“一边……一边”之意时，则习惯上要用as。如： He swung his arms as he walked. 他走路时摆动着手臂。 3、“主长从短”型：即主句是一个持续性动作，而从句是一个短暂性动作，此时可以用as 或when，但不能用while。如： It was raining hard when [as] we arrived. 我们到达时正下着大雨。 二、根据主句与从句动作是否同时发生来区分 1、若主句与从句表示的是两个同时发生的短暂性动作，含有类似汉语“一……就”的意思，英语一般要用as (也可用when)。如： The ice cracked as [when] I stepped onto it. 我一踩冰就裂了。 2、若主句与从句表示的是两个几乎同时发生的短暂性动作，含有类似汉语“刚要……就”“正要……却”的意思，英语一般要用as(也可用when)，且此时通常连用副词just。如： I caught him just when [as] he was leaving the building. 他正要离开大楼的时候，我把他截住了。 三、根据是否具有伴随变化来区分 若要表示主句动作伴随从句动作同时发展变化，有类似汉语“随着”的意思，英语习惯上要用as，而不用when或while。如： The room grew colder as the fire burnt down. 随着炉火逐渐减弱，房间越来越冷。 注：若不是引导从句，而是引出一个短语，则用with，不用as。如： With winter coming on, it’s time to buy warm clothes. 随着冬天到来，该买暖和衣裳了。 四、根据从句动作的规律性来区分 若暗示一种规律性，表示“每当……的时候”，英语一般要用when。如： It’s cold when it snows. 下雪时天冷。 五、根据主从句动作的先后顺序来区分 若主句与从句所表示的动作不是同时发生，而是有先后顺序时，一般要用when。

many-more与much-more的区别

many more与much more的区别 [1] much修饰more只是一种用法。如果不是一定把它们都当成固定词组，而可以是单词的组合的话，它们的用法有区别。 many more本身不是一个整体。比如“many more people”就是很多其他的人、更多的人这种意思。它的后面加上可数名词复数，实际上是这样一种用法：more可以置于数词或者any，some，no，a few，a little，many，much的后面，表示另外的、附加的、超过的。 much more的意思比较丰富，它后面加的是不可数名词。除了与many more 一样也有上述用法外，它还可以作为比较级。这时，more就是一个简单的比较级的形容词，而much是修饰比较级的副词，相同用法还有eg.much bigger，much hotter等，语法结构相同。和much一样具有修饰比较级作用的还有rather，even，a little等等。 同时，more不仅可以单独作为比较级，而且还可以和形容词一起构成比较级，这时的much就是修饰整个比较级而不是单纯修饰much的了。如much more beautiful。但是不用把它想的太复杂，它和more直接作比较级时语法相同，只不过much后面的比较级长了一点而已。 [2] many more后接一个名词一定是个复数可数名词。若不接名词，则more 本身就被看作是一个复数名词，表示复数概念。eg.： ①Some students are against the plan, but many more support it. 一些同学反对这项计划，但是有更多人支持它。 ②We have many more left. 我们还剩下很多。 much more后接一个名词，这个名词一定是个不可数名词。若不接名词，则more本身就被看作是一个不可数名词。如： ①The farmers have produced much more rice. 这些农夫收了更多的稻谷。 ②She has much more to do. 她还有很多事要去做。 many more不可能修饰形容词和副词，而much more和far more, even more, still more 等一样，可以修饰形容词和副词，表示“更加”。eg. ①This TV set is much more expensive. 这台电视机要贵得多。 ②He worked much more carefully on the new design. 在这项新的设计上，他工作努力得多了。

many和much的用法

many和much的用法（作形容词和代词）A many和much many（形容词）用在可数名词之前。 much（形容词）用在不可数名词之前。 He didn’t make many mistakes． 他没犯多少错。 We haven’t much coffee． 家里的咖啡不多了。 many和much的比较级和最高级形式相同，都是more和most： more mistakes／coffee更多的错误／咖啡 most men／damage 几乎全部的男士／几乎所有的损害 many，much，more，most可作代词使用： He gets a lot of letters but she doesn’t get many． 他收到的信很多，可她的信不多。 You have a lot of free time but I haven’t much． 你有许多空闲时间，可我没有。 more和most的用法较灵活，many和much在否定动词后面用得比较多（见上文的例子），但many和much 在肯定动词和疑问动词后用法较受限制。 B many和much与肯定动词连用 many前加上a good／great时可与肯定动词连用。many与much用so／as/too修饰时也可以与肯定动词连用。 I made a good many friends there． 我在那里交了许多朋友。 He has had so many jobs that．

他做过了这么多种工作，以致…… She read as much as she could． 她尽量多读书。 They drink too much（gin）． 他们（杜松子酒）喝得太多了。 many是宾语或宾语的一部分而前面不加任何修饰语时，常常被 a lot/lots of（+名词）或a lot，lots （代词）代替。much是宾语或宾语的一部分时常常被a great／good deal of（+名词）或agreat／good deal （代词）代替： I saw a lot／lots of seabirds．I expect you saw a lot too． 我看到了许多海鸟。想必你也看到了许多。 He spends a lot／lots of/a great deal of money on his house． 他在房子上花很多钱。 既可以用many也可以用a lot（of）作主语或作主语的一部分， 但这里的much通常由其他形式代替。 但much在正规英语中是允许这样用的： Much will depend on what the minister says． 很多事要取决于部长怎么说。 试将肯定句和否定句作一比较： He hasn’t won many races． 他没有赢过几次比赛。 You’ve won a lot／lots of races．／You’ve won a lot．／You’ve won a greatmany（races）． 你赢过多次比赛。 He didn’t eat much fruit． 他没有吃多少水果。 She ate a lot/lots／a great deal of fruit．／She ate a lot／a great deal．
