(2)由prefer构成的短语: 1)prefer A to B意为“喜欢A胜过B、比起B来更喜欢A”,此短语中A和B的形式一样, 可以是名词、代词或者动名词,但必须两个词形式统一。例如: We prefer apples to oranges. 比起桔子来我们更喜欢苹果。 My grandma prefers taking a walk to sitting in front of the TV. 我奶奶宁愿去散步而不愿看电视。 2)prefer to do something rather than do something宁愿做某事,而不愿意做某事 此短语中prefer 的后面用动词不定式,than的后面用省略to的动词不定式。例如: They prefer to stay at home and watch TV, rather than go out for a walk. 他们宁愿呆在家里看电视,也不愿意出去散步。 3. too many &too much (1)too many 意为“太多,大量的”,后跟可数名词复数。例如: There are too many books in the room.

初中英语语法精讲动词不定式用法(教案)

动词不定式用法 动词不定式没有人称和数的变化,在句中不能独立作谓语。但动词不定式具有名词、形容词和副词特征,在句中可以作主语、宾语、宾语补足语、定语、表语和状语等多种成分。另外,动词不定式具有动词特点,可以有自己的宾语和状语,组成动词不定式短语。动词不定式的肯定形式是to+do;其否定形式是not to+do。 下面以动词不定式在句中的作用来予以详细说明。 1.作主语 可以直接作主语。如:To see is to believe. 但在英语中,常用it作形式主语,真正的主语即动词不定式放在后面。如: It's wrong to play tricks on other people. It's our duty to keep our environment clean and tidy. 点击规律:动词不定式在句中作主语时,常放在It is +adj +(for sb.)+(not)to do sth句型中,表示说话人对客观事件的决断,意为:做…..是……的,it仅作形式主语,真正的主语是to do sth It is very interesting to read.读书是有趣的 It is useful to read.看书是有用的 It is healthy to run every day.每天跑步是健康的 It is a little difficulty for me to work out this question.解出这道题对我来说有点难 It is bad not to finish homework.不完成作业是糟糕的 It is bad to be late for school.迟到是糟糕的 It is+adj+of sb +(not)to do sth该句型通常表示说话人对客观事件的惊讶、兴奋、懊悔、难过等感叹情绪,与It is +adj +(for sb.)+(not)to do sth的意义不同。 It is very kind of you to tell me the truth.你能告诉我事实,真是太好了 It is stupid of him to do such a silly thing.他做那件傻事,真是太笨了 It is very clever of you to work out this question. 你能解出这道题目,真是太聪明了 It is very wise of you to read this novel. 你看这本小说,真是太明智了 这个句型中用介词of而不是for的原因是这里的形容词是用来形容人的品质性格的。 类似的词有:careless,careful,clever,considerate,foolish,good,impolite,kind,naughty,nice,silly,stupid,friendly 因此区分是用It is +adj +(for sb.)+(not)to do sth还是It is+adj+of sb +(not)to do sth,要

一名词的分类: 1.名词可以分为专有名词和普通名词,专有名词是某个(些)人,地方,机构等专有的名称,如Beijing,China等。普通名词是一类人或东西或是一个抽象概念的名词,如:book,sadness等。普通名词又可分为下面四类:1)个体名词:表示某类人或东西中的个体,如:gun。 2)集体名词:表示若干个个体组成的集合体,如:family。 3)物质名词:表示无法分为个体的实物,如:air。 4)抽象名词:表示动作、状态、品质、感情等抽象概念,如:work。 二,名词变复数: 2 名词复数的不规则变化1)child---children foot---feet tooth---teeth mouse---mice man---men woman---women 注意:由一个词加man 或woman构成的合成词,其复数形式也是-men 和-women,如an Englishman,two Englishmen。但German不是合成词,故复数形式为Germans;Bowman是姓,其复数是the Bowmans。 2)单复同形,如deer,sheep,fish,Chinese,Japanese ,li,jin,yuan,two li,three mu,four jin等。但除人民币的元、角、分外,美元、英镑、法郎等都有复数形式。如:a dollar, two dollars; a meter, two meters。 3)集体名词,以单数形式出现,但实为复数。例如: people police cattle 等本身就是复数,不能说a people,a police,a cattle,但可以说a person,a policeman,a head of cattle, the English,the British,the French,the Chinese,the Japanese,the Swiss 等名词,表示国民总称时,作复数用,如The Chinese are industries and brave.中国人民是勤劳勇敢的。 4)以s结尾,仍为单数的名词,如: a. maths,politics,physics等学科名词,一般是不可数名词,为单数。 b. news 为不可数名词。 c. the United States,the United Nations 应视为单数。 The United Nations was organized in 1945. 联合国是1945年组建起来的。 d. 以复数形式出现的书名,剧名,报纸,杂志名,也可视为单数。例如: "The Arabian Nights" is a very interesting story-book. 《一千零一夜》是一本非常有趣的故事书。 5)表示由两部分构成的东西,如:glasses (眼镜)trousers,clothes等,若表达具体数目,要借助数量词pair(对,双);suit(套); a pair of glasses; two pairs of trousers等。 6)另外还有一些名词,其复数形式有时可表示特别意思,如:goods货物,waters水域,fishes(各种)鱼。 物质名词和抽象名词可以借助单位词表一定的数量,如a glass of water 一杯水/ a piece of advice一则建议。 5. 定语名词的复数 名词作定语一般用单数,但也有以下例外。 1) 用复数作定语。例如: sports meeting 运动会students reading-room 学生阅览室talks table 谈判桌the foreign languages department 外语系2)man, woman, gentleman等作定语时,其单复数以所修饰的名词的单复数而定。 例如:men workers women teachers gentlemen officials 3)有些原有s结尾的名词,作定语时,s保留。例如: goods train (货车)arms produce武器生产customs papers 海关文件clothes brush 衣刷4)数词+名词作定语时,这个名词一般保留单数形式。例如: two-dozen eggs两打鸡蛋 a ten-mile walk 十英里路two-hundred trees 两百棵树 a five-year plan.一个五年计划

高考英语语法专题精讲精练-定语从句

语法专题一:定语从句 1. 定语从句的几个基本概念: 1) 先行词:即被定语从句修饰的名次或代词,通常位于定从的前面。 2) 先行词在从句中担当成份:根据不同成份,用相应的关系代词或关系副词。 3) 关系代词:即先行词在定从中作主、宾、表、定。 作主语:指物,则用that, which引导,且不能省略;指人,用that, who引导,不省略。 作宾语:即及物动词宾语和介词宾语:指物,用that, which引导,可省略; 指人,用that, who, whom引导,可省略。 注意:如将介词提到了定从之首,先行词指人,只能用whom; 指物只能用which。 作表语:一般指人、指物皆用that, 可省略。 作定语:指人、指物皆用whose,不省略。 4) 关系副词:即先行词在定从中作状语,指时间用when, 地点用where, 原因用why,亦 可用介词+which替代。 所谓作状语:即先行词不能直接放入从句中,需要有一个介词连接,而从句中却没有这个介词。 5) 非限制性定语从句:即用逗号与主句或先行词分开,用于补充说明。 (1) which: 用于指代先行词(物),或整个主句,不能省略。 (2) who / whom: 用于指代先行词(人),不能省略。 (3) all / some of + which / whom: 用于指代先行词的部分。 (4) as为关系代词,“正如、就像”的意思, 引导定从时可置于句首、句中或句末。 注意:在非限制性定从中,不能用that。 2. 一些特殊用法: 1) 一般只用that引导从句的情况: (1) 限制性定语从句中,当先行词被强调,如被any, every, each, few, little, no, some, the only, the very等修饰时; (2) 先行词是不定代词all, few, little, much, something, nothing, anything等时; (3) 先行词被序数词或形容词的最高级所修饰时; (4) 先行词既有人又有物时; (5) 当句中已有who时,为避免重复。 2) 一般只用which引导从句的情况: (1) 引导非限制性定语从句,指前面的某名词或它前面的整个主句时; (2) 引导介词、介词短语提前的定语从句时; (3)当先行词为集体名词时,着眼于整体,用which;着眼于各个成员,用who; (4) 替代某些固定短语中的指示代词,如this, that等, 引导定从。 3) 由as引导的定语从句的几种常见情况: (1) as引导非限制性定语从句,说明整个主句的内容,和which引导定语从句代替整个 句子的区别是:which不能放在句首,而as则可以;在句中,as有“正如”、“就象” 之意,而which则没有此意; (2)当先行词前有the same,such修饰时,或在“so / as…as”结构中,表示“那样…… 以致”,后用关系代词as引导限制性定语从句; (3) 在such…as结构中,as为关系代词,替代先行词,引导的是定语从句;在such…that 结构中,that为连词,引导的是一个完整的结果状语从句。
