小学英语语法基础知识大全蓝本

小学英语语法汇总(蓝本) 可数名词与不可数名词“分家” 一、可数名词与不可数名词的区别 可数名词是可以按个数来计算的普通名词,分为个体名词(表示某类人或事物中的个体,如worker, farmer, desk, factory等)和集体名词(表示作为一个整体来看的一群人或一些事物,如people, family 等)。不可数名词是不能按个数来计算的普通名词,分为物质名词(表示无法分为个体的物质,如meat, rice, water, milk, orange 等)和抽象名词(表示动作、状态、情况、品质等抽象概念,如work, homework, time, health, friendship等)。 强调:不可数名词默认为单数,用is或者was;不要根据some、any、a lot of等词去作判断。 二、可数名词的家务事 可数名词有单数和复数两种形式。指一个人或一件事物时,用单数形式;指两个或多个人或事物时用复数形式。名词由单数形式变成复数形式的规则如下: 1. 一般的名词词尾直接加-s 。如:book → books house → houses day → days 读音:清辅音后读[s],浊辅音和元音后读[z]。 2. 以s,ss,ch,sh, x 结尾的在词尾加-es 。如:bus → buses glass → glasses watch → watches dish → dishes box → boxe s 读音:[iz] 3. 以"辅音字母+y"结尾的,将y改为i再加-es。如city → cities factory → factories 读音:[z] 4. 以f 或fe 结尾的,将f或fe改为v再加-es。如:half → halves leaf → leaves knife → knives wife → wives thief-thieves 读音:[z] 5. 特例(常考) ①child →children mouse→mice ②man →men woman→women policeman →policemen (规律:man →men) ③tomato →tomatoes potato → potatoes [注:黑人英雄土豆西红柿加es其余加-s,,如:photo → photos ] h ero →h eroes negro→negroes 读音:[z] ④foot → feet tooth → teeth [ oo变ee] ⑤sheep, Chinese, Japanese, fish单、复数同形 ⑥people单数形式表示复数意义,要求谓语动词用复数;people的复数形式peoples通常指"多个民族"。 三、不可数名词的家务事 1. 不可数名词没有复数,作句子主语时,谓语动词用单数形式。如:The food is very fresh. 2. 有的不可数名词也可以作可数名词,有复数形式,但意义发生变化。如:water (水) → waters (水域) orange (橘汁) → oranges (橘子) 3. 很多的不可数名词表示泛指时为不可数,表种类时就可数,意义不发生变化。如:fruit → fruits food → foods fish → fishes hair → hairs 4. 计算不可数名词的数量,要在数词和不可数名词之间加上“量词+of”如:a glass of water a piece of paper a bottle of juice 5.判断步骤: ↗如是am、is或was→原形 读句子→读该单词→认识该单词→理解意思→看be动词 ↘如是are或were→加s或es

英语语法基本基础知识——时态

英语的时态问题 英语的时态可以分为:“时”(time) 和“体”(aspect)(又称为态)。时是指动作发生的时间,体是指动作发生时的状态。时间与体就象是坐标里的横轴和纵轴,它们的结合交织出了瞬息万变的时空,也构成了英语动词的时态问题。 时间分为:过去,现在,将来,过去将来 体分为:一般(在某个时间点), 进行(延续某个时间段), 完成(完成某个时间段) 完成进行(延续某个完成的时间段) 如此以来,英语中就有16种时态变化,现在就用动词为write例,看看它们的形式。 注意:里面的斜体字部分,由于时态过于复杂,几乎没有人真正去应用它们,可以忽略不记。 下面就常用的12种时态,(其中还有三种相对用的较少的,请注意)。具体分析一下。 一.一般现在时 表示现在的时间“点”上发生的动作或者状态,常用于以下的情况 1、经常重复发生的动作或存在的状态,多与often, always, usually, sometimes, everyday, 等时 间状语连用。 He takes a walk after supper everyday My mother and father work at the same company. 2、表示性格,特征,能力。 Mr. Smith hates fish and never eats any. 3、表示客观真理或者普遍事实。

The sun rises in the east. 二.一般过去时 表示过去某时发生的动作或者状态,常和表示过去某个时间“点”的时间状语(yesterday, last week, 3 years ago, in 1987)连用 She bought a car last week. He came to help me at that time. 三.一般将来时 表示将来的时间“点”上发生的动作或者状态。 The train will arrive soon. We shall know the news tomorrow. 四.过去将来时 过去某个时间“点”上将要发生的动作或状态。 I asked her where she would spend her holiday. I told my father that I should go home next Monday. 五.现在进行时 表示现在的时间“段”上正在延续进行的动作或者状态。 I’m doing some washing. What are you doing? 六.过去进行时 在过去某一个时间“段”正在延续进行的动作。 I was working in my office at eight o’clock yesterday evening. He was making a phone call when I saw him. 七.将来进行时 在将来某个时间“段”正在发生的动作,一般表示一种猜测和未来的计划,一般不太常用。What will you be doing at 3 o’clock tomorrow afternoon? (明天下午三点你将在做什么哪) 八.现在完成时 表示动作在一个时间“段”的完成,而且这个时间段是从过去某一点延续到现在的。经常跟时间状语since 1987,for 10 hours , by the last year相连。 My brother has been ill for 3 days. I have not seen her since 1991. 九.过去完成时 在过去的某个时间“段”里动作的完成,从过去的一点再到过去的另一点。或者称为过去的过去。 He said that he had written her a letter. Helen rang me up after I had gone to sleep.

英文日期表示方法

月份名称词 January n. 一月,正月(略写为 Jan.) February n. 二月(略写为 Feb.) March n. 三月(略写为 Mar.) April n. 四月(略写为 Apr.) May/mei/ n. 五月 June n. 六月(略写为 Jun.) July n. 七月(略写为 Jul.) August n. 八月(略写为 Aug.) September n. 九月(略写为 Sept.) October n. 十月(略写为 Oct.) November n. 十一月(略写为 Nov.) December n. 十二月(略写为 Dec.) 英文日期表达英文日期表达方式 [一]书写方面先看下面的两个例子: 1. 1986 年 10 月 23 日→October 23(rd), 1986 2. 2002 年 1 月 17 日→January 17(th), 2002 从上面的例子可以看出,英语日期的表达与汉语不同。英语表达的顺序为\"月、日、年\",因此 2004 年 11 月 8 日就可写成 November 8th, 2004,还可表示为 November eighth, 2004。另外,也可写成\"日、月、年\",8th November, 2004 即 the eighth of November, 2004。 [二] 朗读方面在朗读时,"月份"一般直接用英语读出;"日"则要读成"the 序数词";年份,一般分为两个单位来读,前两个数为一个单位,后两个数为一个单位。 1982 年读作nineteen eighty-two, 1900 年读作 nineteen hundred。如果是三位数,先读第一位,再把后两个数合起来读。如:984年可读为nine eighty-four,757 年读成 seven fifty-seven。另外,像 2000 年一般读成 two thousand, 2001 年则读成 two thousand and one,以此类推,2004 年应读成 two thousand and four。 January 12th, 1993 读成 January the twelfth, nineteen ninety-three。 英语日期的表示法:英语中月份和星期名称都是专有名词(独一无二的东西比如月亮太阳),它们的首字母必须大写,并且前面无需用冠词。用英语表示日期,其顺序为“月日年”,日和年之间需用逗号隔开。如:August 2nd, 2003(2003 年 8 月 2 日)也可以用“日月年”来表示。如:10th May,2003(2003 年 5 月 10 日)。 英语日期前介词的使用:若指在哪一年或哪一月,则用介词 in,若具体到某一天,则需用介词 on 美英的表达方式是有差别的在日期方面,美英的表达方式是有差别的。以日为先,

英语时间表达法总结

英语时间表达法(一) 英语时间通常用以下两种方式表达: 1.直接表达法: 1) 整点表达法: 用“基数词+o’clock”来表示整点,(o’clock要用单数),当然“o’clock”也可省略不写。 例:十一点钟: eleven o’clock 十二点钟: twelve o’clock 2) 非整点表达法: 用“基数词按钟点 + 分钟”的顺序直接写出时间。 (与整点表达法不同的是结尾无需加o’clock) 例:九点十分: nine ten 八点四十分: eight forty 2.间接表达法 1) 用“分钟+ past +钟点”来表示:(“past”是介词,意思是“过”) 条件:分钟数少于或等于30分。 例:七点二十分 twenty past seven 三点十二分: twelve past three 2) 用“(60分钟-原分钟数) + to + (原钟点数+1)”来表示:(“to”是介词,意思是“差”) 条件:原分钟数大于30分。 例:二点五十分 ten to three 意思是三点差十分。(其中的分钟数ten是由60分减去原分钟数五十分 得到的,钟点数three是由原来的钟点数2加1得到的) 七点四十二分: eighteen to eight 注: 1.当分钟数为15时,可用 a quarter (一刻钟)表示。 如:十点十五分: a quarter past ten 三点四十五分: a quarter to four 当分钟数为30时,可用 half (半)表示。 如:五点三十分: half past five 一点半: half past one (在直接表达法中,十五分钟不能用a quarter 表示,只能用基数词fifteen表示,三十分钟不能用half表示,只能用基数词thirty来表示) 2.若想表明所说时间是上午,只需在时间后加上am。 如:It’s six thirty am. (现在是早上六点三十分) 若想表达下午,只需在时间后加上pm。 如:It’s six thirty pm. (现在是下午六点三十分) 3.如果表达的时间不是很精确,可以时间前加about(大约) 如:It’s about seven o’clock (现在大约七点钟) 4.在时间前面应用介词“at”表示“在” 如:I go to school at seven ten. (我在七点十分上学) 英语时间表达法(二) 用英语表达时刻主要有以下两种方法: ?直接表示法(先时后分)。如: 9 : 25 读作: nine twenty-five 12 : 30 读作: twelve thirty ; twelve-thirty ?添加介词表示法(先分后时)。如: ( 1 )表示“几点过几分”(在 30 分钟之内),用介词 past ,其结构是“分钟 +past+ 钟

英语倍数表达法基本句型

一. 表达倍数的三个基本句型 1.“A+be动词/谓语动词+倍数+as+形容词/副词原级+as+B”,表示“A正好是B的多少倍”。例如: Asia is four times as large as Europe. 亚洲的面积是欧洲的四倍。 This big stone is three times as heavy as that one. 这块大石头的重量是那块的三倍。 The plane flew ten times as high as the kite. 那架飞机的飞行高度是那只风筝的十倍。 2. “A+be动词/谓语动词+倍数+形容词/副词比较级+than+B”,表示“A比B大(长、高、宽等)多少倍”。例如: This rope is twice longer than that one. 这根绳子比那根绳子长两倍(是那根绳子三倍长)。 This hall is five times bigger than our classroom. 这个大厅比我们的教室大五倍(是我们教室的六倍大)。 The car runs twice faster than that truck. 这辆小车的速度比那辆卡车快两倍(是那辆卡车的三倍快)。 3. “A+be动词+倍数+the size/height/length/width, etc+of+B”,表示“A正好是B的多少倍”。例如: This street is four times the length of that one.这条街是那条街的四倍长。 This hill is four times the height of that small one.这座山的高度是那座小山的四倍。 除表达倍数的三个基本句型外,我们还要掌握其基本句型的7种变形。 1. “ ... times as many/much+名词+as+被比对象”。例如: There is four times as much water in this pot as in that one.这个壶里装的水是那个壶里的四倍。 There are six times as many students as we expected.学生数量是我们预期的六倍。 2. “ ... times+more+名词(可数或不可数)+than+被比对象”。例如: There are five times more books in our library than in yours.我们图书馆里的书比你们图书馆多五倍多。 We have produced twice more grain this year than we did last year. 我们今年生产的粮食是去年的两倍多。 3.“ ... times+over+被比对象”。例如: The grain output in that village is twice over that of 2002. 那个村的粮食产量是2002年的两倍多。 4. “ ... times+that+of+被比对象”。例如: In this workshop, the output of July was times that of January. 这个车间7月份的产量是1月份的倍。 5. “...times+compared with+被比对象”。例如: The number of the students in our school has increased 4 times compared with 1980. 我们学校的学生人数比1980年增加了四倍。 6. “...times+what+从句”。例如: The production is now three times what it was ten years ago. 现在的产量是十年前的三倍。
