知识点名称:实义动词的过去式,形容词的比较级,形容词的最高级,不定式

考点名称:实义动词的过去式
  • 表示一般过去式的动词通常用动词的过去式形式来表示,而动词的过去式是在动词原形的基础上变化的。
    动词的过去式可分为规则动词和不规则动词。
  • 实意动词过去式变化规则:

    分类构成例句
    一般情况下在词尾直接加edask—asked
    work—worked
    以不发音的e结尾只加d

    love—loved

    dance—danced

    以辅音字母加y结尾变y为i,再加-edtry—tried
    study—studied
    以一个元音字母和一个辅音结尾的
    重读音节结尾的动词
    先双写末尾一个字母,再加edstop—stopped
    permit—permitted
    “-ed”的读音规则1.在清辅音后面读[t],如:help—helped[helpt]
    2.在浊辅音或元音后读[d],如:learn—learned
    3.在[t]和[d]后读[id],如:want—wantedneed—needed
    注:以l结尾的动词,尾音节重读时,双写l,如control—controlled;
    尾音节不重读时,双不双写都可以,如travel—traveled/traveled。
    特例:picnic—picnicked,另外还有很多动词的过去式是不合乎上述规则的,常见的有:
    常用的有:
    begin—began,         bring—brought,        come—came,        draw—drew,
    drink—drank,          drive—drove,          eat—ate,                feel—felt,

考点名称:不定式
  • 动词不定式:
    指由to加上动词原形(而且只能是动词原形)所构成的一种非限定性动词,但在有些情况下to可以省略。
    动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。
  • 动词不定式可以作以上各种成分,但它毕竟是动词,所以有动词的属性。
    动词不定式及其短语还可以有自己的宾语、状语,虽然动词不定式在语法上没有表面上的直接主语,但它表达的意义是动作,这一动作一定由使动者发出。
    这一使动者我们称之为逻辑主语,其形式如下:
    时态主动形式 被动形式 
    一般式(not) to do(not) to be done
    完成式(not) to have done(not) to have been done
    进行式(not) to be doing 
    完成进行式(not) to have been doing 
  • 不定式的用法:
    1、不定式作主语
    例如:To remember this is very important.
    注意:为了避免头重脚轻,在许多情况下,通常都将作主语的不定式置于句子后部,而在句首主语位置使用形式主语it。
    例如:It is very important to remember this.
    2、不定式作表语
    例如:He seems to be ill.
    注意:不定式作表语主要有三种情况,一是用于seem, appear, prove等系动词之后的不 定式(尤其是to be),
    二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形,
    三是表示想法、约定、义务、命令、可能性、命运等,如: 
    You are to come when I call.
    3、不定式作宾语
    例如:I can not afford to buy a car.
    注意:
    ①不定式不仅用作动词的宾语,还可用作个别介词(but, except)的宾语。
    例如:I had no choice but to wait.
    ②当作宾语的不定式后跟有宾语补足语时,通常要用形式宾语it代替不定式,并将真正的宾语不定式置于宾语补足语之后
    例如:I find it difficult to learn Japanese well.
    4、不定式作宾语补足语
    例如:Who taught you to drive?
    5、不定式作定语
    例如:I have a question to ask you.
    注意:有的名词(如way, chance, right等)后用作不定式可换成of doing sth.
    如:It is the best way to do (of doing) it.
    但是以下名词后接不定式作定语时通常不能换成of doing sth.
    attempt  courage  decision  effort  fortune  failure  invitation  wish
    6、不定式作状语
    例如:I went to France to learn French.
