1、初中英语语法难点及教学策略,贵阳十中 余 嬿,一、引 言,英语作为语言的一种，其学习也要遵循它的基本规律。,英语语法能力的掌握是掌握其它诸多 能力的基础。,有了一定的语法基础，对于学生能 准确的表达、正确的理解,有着 至关重要的作用。,我在初中英语语法教学中的一些方法,演绎归纳穿插教学法比较教学法图表教学法表格教学法口诀教学法,1.演绎，归纳穿插教学法：,案例一：语法：一般将来时一、概念：即将发生的动作或存在的状态。二、构成：主语+will/be going to+V原+其它三、标志词：tomorrow next in+将来的段时间等,例如：,我们明天要去看电影。We will go to s

2、ee a movie tomorrow.2.我和我的父母下个星期天要去看我的爷爷奶奶。My parents and I will/are going to see my grandparents next Sunday.,案例二：I like music that I can dance to.先行词 指物 关系代词 作宾语 可省I like musicians who write their own songs.先行词 指人 关系代词 作主语 不可省She likes singers who sing the words clearly.先行词 指人 关系代词 作主语 不可省He doesn

3、t like songs that are too loud.先行词 指物 关系代词 作主语 不可省,2.比较教学法：案例三：,1.tomorrow,at home.free this night,you.you,English well.a doctor,the sick boy.,+，+,If,If,If,it,I,主语,rains,am,V原/现三单,we,I,主语,will,can,Will/can,stay,help,V原,If,If,If,I,he,主语,+，+,were,were,V过去式,I,he,主语,would,could,would/could,study,help,V原

4、,3.图表教学法,4.表格教学法：,me,us,you,HerHimit,them,5.口诀教学法：,1）名词由单数变为复数，以o结尾的词有：Negro,hero,tomato,potato.我们可以这样说：黑人，英雄吃土豆和西红柿。2）名词由单数变为复数，以f(fe)结尾的词有：leaf,half,wife,knife,self,wolf,thief.我们可以这样说：树叶，半数自己数，妻子拿刀去割粮，然后窜出一只狼，就像强盗逃命忙。3）基数词变序数词的口诀：一，二，三要全变，八去t,九去e,ve要用f替，y变成ie,th最后加上去，若是碰到几十几，只变个位就可以。,区别：sometimes,

5、some times,sometime,some time,口诀：有“s”是“有时”，无“s”是“某时”，有“s”分开“好几次”，无“s”分开“一段时”,二、英语句子结构和英语句子成分讲解及练习,1.She came 主+不及物动词 2.She likes English。主+及物动词+宾语3.She is hungry.主+系+表4.She gave Tom a gift 主+及物动词+间接宾语+直接宾语,5.She bought a book for me.主+动词+直接宾语+间接宾语6.She makes her mother angry 主+动词+宾语+宾语补足语7.The teach

23、在关系，即：它指存在的有，通常带有一个地点状语，意为“某地（时候）有某人/某物”。句式中的主语只能为表泛指的名词或名词词组。Eg:1.There is a blackboard in the classroom.2.There are five minutes to go.3.There are two old women and a man waiting for you at the gate.4.There is a pen and two pencils on the desk.,从上面例句可以看出，该句式中be动词的单复数形式取决于以下两种情况：（1）该句式中只有一个主语，主语为单数

24、时，be动词用单数；主语若为复数，be动词也用复数。（2）该句式中有几个并列主语，则按就近原则处理，即与靠近be动词的第一个主语保持一致。例如：1.There_ a tree in front of the building.2.There _ three apples on the table.3.There _ only two pens,a dictionary and a textbook on the desk.,is,are,are,拓展：There be句式中，be动词有各种变化形式。（1）be动词有时态变化，可以为一般现在时、一般过去时、现在完成时、过去完成时、将来时等。例如：

25、1.There are a lot of people in the meeting-room.2.There was little left.3.There have been many such traffic accidents in the past few years.4.When he got there,he found there had been no one waiting for him in the room.5.Without air,there would be no living things.6.There is going to be a storm tomo

26、rrow morning.,（2）There be句式中，be之前可以有情态动词。常用句型为：There may be sb./sth+某地.(可能有某人/某物在某地)There must be sb./sth+某地.(一定是有某人/某物在某地)There may be some people who dont like the film.2.There must be something visiting the homes in our neighborhood.,互动二：英语中时态的教法,一般现在时 一般过去时一般将来时现在进行时现在完成时现在完成时进行时过去完成时过去将来时,Now:一般现在时：do does现在进行时：be doingPast:一般过去时：did现在完成时：have/has done现在完成进行时：have/has been doing过去完成时：had doneFuture:Will/shall doBe going to doBe to do,以动词do为例,Thanks for your listening!,
