初二上英语新目标各单元知识点总结(DOC 14页).docx

1、U1 where did you go on vacation?1.短语：decide to do决定decide on/uponfeel like2.语法：一般过去时口诀：过去式之歌过去式构成有方法，一般词尾加ed。如果词尾有个e，直接加d就可以。辅音字母y在尾，变y为i加ed。“一辅重闭”作尾巴，双写之后ed加。标准过去式加ed，少量不规则分别记。am和is对was，are要变were没问题。have和has用had，do和does变did。一般过去时表示过去某个时间发生的动作或存在的状态。常和表示过去的时间状语连用。如：lastyear,yesterday等；也可表示过去经常反复发生的动

2、作，常和often,always等频率副词连用。1.一般过去时的形式：动词be:第一人称单数和第三人称单数用was,其余的人称一律用were。动词have:一律用had,没有人称和数的变化。行为动词：一律用过去式，没有人称和数的变化，行为动词的过去式有两类，一类是规则动词，另一类是不规则动词。3. 复合不定代词something,somebody,someone,anything,anybody,anyone,nothing,nobody,noone,everything,everybody,everyone等。（1）它们在句中可用作主语、宾语或表语，但不能用作定语。（2）something,

3、someone等和anything,anyone等的区别与some和any的区别一样，前者一般用于肯定句，后者一般用于否定句、疑问句或条件句。具体使用时应注意以下几个语法特点：特点1其定语修饰语的位置：复合不定代词受定语修饰时，定语应放在它们后面。如：Thereisnothingwrongwiththeradio.这收音机没有毛病。Haveyouseenanyoneanybodyfamous?你见过名人吗?特点2复合不定代词与指示代词：指人的复合不定代词若用作主语，其谓语动词一般用单数，相应的人称代词和物主代词也用单数he,him,his(不一定指男性)。但在非正式文体中常用复数代词they,

4、them,their。如：Ifanybodycomes,askhimthemtowait.要是有人来，让他等着。指事物的复合不定代词若用作主语，谓语动词只能用单数，相应的人称代词也只能用it，而不用they。如：Everythingisready,isntit?一切都准备好了，是吗?特点3其后是否接of短语：anyone,everyone等只能指人，不能指物，且其后一般不接of短语。若是指物或后接of短语，可用anyone,everyone(分开写)。如：anyoneoftheboys(books)孩子们(书)当中的任何一个(本)everyoneofthestudents(schools)每一

5、个学生(一所学校)4.enough 形容词副词前，to do 后5. few,afew,little,alittle虽然都表示“少”，但（1）few,afew是可数的,little,alittle是不可数的。（2）afew,alittle含肯定意味，few,little含否定意味。这里所谓的“肯定意味”和“否定意味”应该这样来理解：同样是半杯水，口渴者会认为：Thereislittlewaterintheglass.而不口渴的人则会认为：Thereisalittlewaterintheglass.6. because是连词，其后接句子；becauseof是复合介词，其后接名词、代词、动名词、w

Here are the results of the activity survey of Green High School.本句为倒装句here, there, out, in, up, down等副词开头并起强调作用时，可采用倒装结构，将副词置于句首，主谓语交换位置就好。其中主语须为名词，谓语的单复数形式由名词的数来决定。结构：Here+谓语+主语Here comes a bu

9、s.
